Monetary policy

Last updated

Monetary policy is the policy adopted by the monetary authority of a country that controls either the interest rate payable on very short-term borrowing or the money supply, often targeting inflation or the interest rate to ensure price stability and general trust in the currency. [1] [2] [3]

Monetary authority entity which controls the money supply of a given currency, generally a central bank

In finance and economics, a monetary authority is the entity which controls the money supply of a particular currency, often with the objective of controlling inflation, interest rates, real GDP or the unemployment rate. With its monetary tools, a monetary authority is able to effectively influence the development of short-term interest rates for that currency, but can also influence other parameters which control the cost and availability of money.

Interest rate Percentage of a sum of money charged for its use

An interest rate is the amount of interest due per period, as a proportion of the amount lent, deposited or borrowed. The total interest on an amount lent or borrowed depends on the principal sum, the interest rate, the compounding frequency, and the length of time over which it is lent, deposited or borrowed.

In the United States, federal funds are overnight borrowings between banks and other entities to maintain their bank reserves at the Federal Reserve. Banks keep reserves at Federal Reserve Banks to meet their reserve requirements and to clear financial transactions. Transactions in the federal funds market enable depository institutions with reserve balances in excess of reserve requirements to lend reserves to institutions with reserve deficiencies. These loans are usually made for one day only, that is, "overnight". The interest rate at which these deals are done is called the federal funds rate. Federal funds are not collateralized; like eurodollars, they are an unsecured interbank loan.

Further goals of a monetary policy are usually to contribute to the stability of gross domestic product, to achieve and maintain low unemployment, and to maintain predictable exchange rates with other currencies.

Gross domestic product market value of goods and services produced within a country

Gross domestic products (GDP) is a monetary measure of the market value of all the final goods and services produced in a specific time period, often annually. GDP (nominal) per capita does not, however, reflect differences in the cost of living and the inflation rates of the countries; therefore using a basis of GDP per capita at purchasing power parity (PPP) is arguably more useful when comparing differences in living standards between nations.

Unemployment People without work and actively seeking work

Unemployment, or joblessness, is a situation in which able-bodied people who are looking for a job cannot find a job.

Monetary economics provides insight into how to craft an optimal monetary policy. In developed countries, monetary policy has been generally formed separately from fiscal policy, which refers to taxation, government spending, and associated borrowing. [4]

Monetary economics is the branch of economics that studies the different competing theories of money: it provides a framework for analyzing money and considers its functions, and it considers how money, for example fiat currency, can gain acceptance purely because of its convenience as a public good. The discipline has historically prefigured, and remains integrally linked to, macroeconomics. This branch also examines the effects of monetary systems, including regulation of money and associated financial institutions and international aspects.

Fiscal policy use of government revenue collection and spending to influence the economy

In economics and political science, fiscal policy is the use of government revenue collection and expenditure (spending) to influence a country's economy. The use of government revenues and expenditures to influence macroeconomic variables developed as a result of the Great Depression, when the previous laissez-faire approach to economic management became discredited. Fiscal policy is based on the theories of the British economist John Maynard Keynes, whose Keynesian economics indicated that government changes in the levels of taxation and government spending influences aggregate demand and the level of economic activity. Fiscal and monetary policy are the key strategies used by a country's government and central bank to advance its economic objectives. The combination of these policies enables these authorities to target the inflation and to increase employment. Additionally, it is designed to try to keep GDP growth at 2%–3% and the unemployment rate near the natural unemployment rate of 4%–5%. This implies that fiscal policy is used to stabilize the economy over the course of the business cycle.

A tax is a compulsory financial charge or some other type of levy imposed upon a taxpayer by a governmental organization in order to fund various public expenditures. A failure to pay, along with evasion of or resistance to taxation, is punishable by law. Taxes consist of direct or indirect taxes and may be paid in money or as its labour equivalent. The first known taxation took place in Ancient Egypt around 3000–2800 BC.

Monetary policy is referred to as being either expansionary or contractionary. Expansionary policy occurs when a monetary authority uses its tools to stimulate the economy. An expansionary policy maintains short-term interest rates at a lower than usual rate or increases the total supply of money in the economy more rapidly than usual. It is traditionally used to try to combat unemployment in a recession by lowering interest rates in the hope that less expensive credit will entice businesses into expanding. This increases aggregate demand (the overall demand for all goods and services in an economy), which boosts short-term growth as measured by gross domestic product (GDP) growth. Expansionary monetary policy usually diminishes the value of the currency relative to other currencies (the exchange rate). [5]

In economics, a recession is a business cycle contraction when there is a general decline in economic activity. Recessions generally occur when there is a widespread drop in spending. This may be triggered by various events, such as a financial crisis, an external trade shock, an adverse supply shock or the bursting of an economic bubble. In the United States, it is defined as "a significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in real GDP, real income, employment, industrial production, and wholesale-retail sales". In the United Kingdom, it is defined as a negative economic growth for two consecutive quarters.

In macroeconomics, Aggregate Demand (AD) or Domestic Final Demand (DFD) is the total demand for final goods and services in an economy at a given time. It is often called effective demand, though at other times this term is distinguished. This is the demand for the gross domestic product of a country. It specifies the amounts of goods and services that will be purchased at all possible price levels.

Exchange rate rate at which one currency will be exchanged for another

In finance, an exchange rate is the rate at which one currency will be exchanged for another. It is also regarded as the value of one country's currency in relation to another currency. For example, an interbank exchange rate of 114 Japanese yen to the United States dollar means that ¥114 will be exchanged for each US$1 or that US$1 will be exchanged for each ¥114. In this case it is said that the price of a dollar in relation to yen is ¥114, or equivalently that the price of a yen in relation to dollars is $1/114.The government has the authority to change exchange rate when needed.

The opposite of expansionary monetary policy is contractionary monetary policy, which maintains short-term interest rates higher than usual or which slows the rate of growth in the money supply or even shrinks it. This slows short-term economic growth and lessens inflation. Contractionary monetary policy can lead to increased unemployment and depressed borrowing and spending by consumers and businesses, which can eventually result in an economic recession if implemented too vigorously. [6]

Inflation increase in the general price level of goods and services in an economy over a period of time

In economics, inflation is a sustained increase in the general price level of goods and services in an economy over a period of time. When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation reflects a reduction in the purchasing power per unit of money – a loss of real value in the medium of exchange and unit of account within the economy. The opposite of inflation is deflation, a sustained decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index, usually the consumer price index, over time.

History

Monetary policy is associated with interest rates and availability of credit. Instruments of monetary policy have included short-term interest rates and bank reserves through the monetary base. [7] For many centuries there were only two forms of monetary policy: (i) Decisions about coinage; (ii) Decisions to print paper money to create credit. Interest rates, while now thought of as part of monetary authority, were not generally coordinated with the other forms of monetary policy during this time. Monetary policy was seen as an executive decision, and was generally in the hands of the authority with seigniorage, or the power to coin. With the advent of larger trading networks came the ability to set the price between gold and silver, and the price of the local currency to foreign currencies. This official price could be enforced by law, even if it varied from the market price.

Monetary base portion of the commercial banks reserves that are maintained in accounts with their central bank plus the total currency circulating in the public

In economics, the monetary base in a country is the total amount of bank notes and coins circulating in the economy. This includes:

Credit loan

Credit is the trust which allows one party to provide money or resources to another party wherein the second party does not reimburse the first party immediately, but promises either to repay or return those resources at a later date. In other words, credit is a method of making reciprocity formal, legally enforceable, and extensible to a large group of unrelated people.

Seigniorage, also spelled seignorage or seigneurage, is the difference between the value of money and the cost to produce and distribute it. The term can be applied in two ways:

Paper money originated from promissory notes called "jiaozi" in 7th century China. Jiaozi did not replace metallic currency, and were used alongside the copper coins. The successive Yuan Dynasty was the first government to use paper currency as the predominant circulating medium. In the later course of the dynasty, facing massive shortages of specie to fund war and their rule in China, they began printing paper money without restrictions, resulting in hyperinflation.

With the creation of the Bank of England in 1694, [8] which acquired the responsibility to print notes and back them with gold, the idea of monetary policy as independent of executive action began to be established. [9] The goal of monetary policy was to maintain the value of the coinage, print notes which would trade at par to specie, and prevent coins from leaving circulation. The establishment of central banks by industrializing nations was associated then with the desire to maintain the nation's peg to the gold standard, and to trade in a narrow band with other gold-backed currencies. To accomplish this end, central banks as part of the gold standard began setting the interest rates that they charged, both their own borrowers, and other banks who required liquidity. The maintenance of a gold standard required almost monthly adjustments of interest rates. The gold standard is a system under which the price of the national currency is measured in units of gold bars and is kept constant by the government's promise to buy or sell gold at a fixed price in terms of the base currency. The gold standard might be regarded as a special case of "fixed exchange rate" policy, or as a special type of commodity price level targeting. Nowadays this type of monetary policy is no longer used by any country. [10]

During the period 1870–1920, the industrialized nations set up central banking systems, with one of the last being the Federal Reserve in 1913. [11] By this point the role of the central bank as the "lender of last resort" was understood. It was also increasingly understood that interest rates had an effect on the entire economy, in no small part because of the marginal revolution in economics, which demonstrated how people would change a decision based on a change in the economic trade-offs.

Monetarist economists long contended that the money-supply growth could affect the macroeconomy. These included Milton Friedman who early in his career advocated that government budget deficits during recessions be financed in equal amount by money creation to help to stimulate aggregate demand for output. [12] Later he advocated simply increasing the monetary supply at a low, constant rate, as the best way of maintaining low inflation and stable output growth. [13] However, when U.S. Federal Reserve Chairman Paul Volcker tried this policy, starting in October 1979, it was found to be impractical, because of the highly unstable relationship between monetary aggregates and other macroeconomic variables. [14] Even Milton Friedman later acknowledged that direct money supply targeting was less successful than he had hoped. [15]

Therefore, monetary decisions today take into account a wider range of factors, such as:

Monetary policy instruments

Conventional instrument

The central bank influences interest rates by expanding or contracting the monetary base, which consists of currency in circulation and banks' reserves on deposit at the central bank. Central banks have three main tools of monetary policy: open market operations, the discount rate and the reserve requirements.

An important tool with which a central bank can affect the monetary base is open market operations , if its country has a well developed market for its government bonds. This entails managing the quantity of money in circulation through the buying and selling of various financial instruments, such as treasury bills, company bonds, or foreign currencies, in exchange for money on deposit at the central bank. Those deposits are convertible to currency, so all of these purchases or sales result in more or less base currency entering or leaving market circulation. For example, if the central bank wishes to lower interest rates (executing expansionary monetary policy), it purchases government debt, thereby increasing the amount of cash in circulation or crediting banks' reserve accounts. Commercial banks then have more money to lend, so they reduce lending rates, making loans less expensive. Cheaper credit card interest rates boost consumer spending. Additionally, when business loans are more affordable, companies can expand to keep up with consumer demand. They ultimately hire more workers, whose incomes rise, which in its turn also increases the demand. This tool is usually enough to stimulate demand and drive economic growth to a healthy rate. Usually, the short-term goal of open market operations is to achieve a specific short-term interest rate target. In other instances, monetary policy might instead entail the targeting of a specific exchange rate relative to some foreign currency or else relative to gold. For example, in the case of the United States the Federal Reserve targets the federal funds rate, the rate at which member banks lend to one another overnight; however, the monetary policy of China is[ when? ] to target the exchange rate between the Chinese renminbi and a basket of foreign currencies.

If the open market operations do not lead to the desired effects, a second tool can be used: the central bank can increase or decrease the interest rate it charges on discounts or overdrafts (loans from the central bank to commercial banks, see discount window). If the interest rate on such transactions is sufficiently low, commercial banks can borrow from the central bank to meet reserve requirements and use the additional liquidity to expand their balance sheets, increasing the credit available to the economy.

A third alternative is to change the reserve requirements. The reserve requirement refers to the proportion of total liabilities that banks must keep on hand overnight, either in its vaults or at the central bank. Banks only maintain a small portion of their assets as cash available for immediate withdrawal; the rest is invested in illiquid assets like mortgages and loans. Lowering the reserve requirement frees up funds for banks to increase loans or buy other profitable assets. This is expansionary because it creates credit. However, even though this tool immediately increases liquidity, central banks rarely change the reserve requirement because doing so frequently adds uncertainty to banks’ planning. The use of open market operations is therefore preferred.

Unconventional monetary policy at the zero bound

Other forms of monetary policy, particularly used when interest rates are at or near 0% and there are concerns about deflation or deflation is occurring, are referred to as unconventional monetary policy. These include credit easing, quantitative easing, forward guidance, and signaling. [16] In credit easing, a central bank purchases private sector assets to improve liquidity and improve access to credit. Signaling can be used to lower market expectations for lower interest rates in the future. For example, during the credit crisis of 2008, the US Federal Reserve indicated rates would be low for an "extended period", and the Bank of Canada made a "conditional commitment" to keep rates at the lower bound of 25 basis points (0.25%) until the end of the second quarter of 2010.

Further heterodox monetary policy proposals include the idea of helicopter money whereby central banks would create money without assets as counterpart in their balance sheet. The money created could be distributed directly to the population as a citizen's dividend. This option has been increasingly discussed since March 2016 after the ECB's president Mario Draghi said he found the concept "very interesting". [17]

Nominal anchors

A nominal anchor for monetary policy is a single variable or device which the central bank uses to pin down expectations of private agents about the nominal price level or its path or about what the central bank might do with respect to achieving that path. Monetary regimes combine long-run nominal anchoring with flexibility in the short run. Nominal variables used as anchors primarily include exchange rate targets, money supply targets, and inflation targets with interest rate policy. [18]

Types

In practice, to implement any type of monetary policy the main tool used is modifying the amount of base money in circulation. The monetary authority does this by buying or selling financial assets (usually government obligations). These open market operations change either the amount of money or its liquidity (if less liquid forms of money are bought or sold). The multiplier effect of fractional reserve banking amplifies the effects of these actions on the money supply, which includes bank deposits as well as base money.

Constant market transactions by the monetary authority modify the supply of currency and this impacts other market variables such as short-term interest rates and the exchange rate.

The distinction between the various types of monetary policy lies primarily with the set of instruments and target variables that are used by the monetary authority to achieve their goals.

Monetary Policy:Target Market Variable:Long Term Objective:
Inflation TargetingInterest rate on overnight debtA given rate of change in the CPI
Price Level TargetingInterest rate on overnight debtA specific CPI number
Monetary AggregatesThe growth in money supplyA given rate of change in the CPI
Fixed Exchange RateThe spot price of the currencyThe spot price of the currency
Gold StandardThe spot price of goldLow inflation as measured by the gold price
Mixed PolicyUsually interest ratesUsually unemployment + CPI change

The different types of policy are also called monetary regimes, in parallel to exchange-rate regimes. A fixed exchange rate is also an exchange-rate regime; The gold standard results in a relatively fixed regime towards the currency of other countries on the gold standard and a floating regime towards those that are not. Targeting inflation, the price level or other monetary aggregates implies floating the exchange rate unless the management of the relevant foreign currencies is tracking exactly the same variables (such as a harmonized consumer price index).

Inflation targeting

Under this policy approach the target is to keep inflation, under a particular definition such as the Consumer Price Index, within a desired range.

The inflation target is achieved through periodic adjustments to the central bank interest rate target. The interest rate used is generally the overnight rate at which banks lend to each other overnight for cash flow purposes. Depending on the country this particular interest rate might be called the cash rate or something similar.

As the Fisher effect model explains, the equation linking inflation with interest rates is the following:

π = i - r

where π is the inflation rate, i is the home nominal interest rate set by the central bank, and r is the real interest rate. Using i as an anchor, central banks can influence π. Central banks can choose to maintain a fixed interest rate at all times, or just temporarily. The duration of this policy varies, because of the simplicity associated with changing the nominal interest rate.

The interest rate target is maintained for a specific duration using open market operations. Typically the duration that the interest rate target is kept constant will vary between months and years. This interest rate target is usually reviewed on a monthly or quarterly basis by a policy committee. [18]

Changes to the interest rate target are made in response to various market indicators in an attempt to forecast economic trends and in so doing keep the market on track towards achieving the defined inflation target. For example, one simple method of inflation targeting called the Taylor rule adjusts the interest rate in response to changes in the inflation rate and the output gap. The rule was proposed by John B. Taylor of Stanford University. [19]

The inflation targeting approach to monetary policy approach was pioneered in New Zealand. It has been used in Australia, Brazil, Canada, Chile, Colombia, the Czech Republic, Hungary, New Zealand, Norway, Iceland, India, Philippines, Poland, Sweden, South Africa, Turkey, and the United Kingdom.

Price level targeting

Price level targeting is a monetary policy that is similar to inflation targeting except that CPI growth in one year over or under the long term price level target is offset in subsequent years such that a targeted price-level trend is reached over time, e.g. five years, giving more certainty about future price increases to consumers. Under inflation targeting what happened in the immediate past years is not taken into account or adjusted for in the current and future years.

Uncertainty in price levels can create uncertainty around price and wage setting activity for firms and workers, and undermines any information that can be gained from relative prices, as it is more difficult for firms to determine if a change in the price of a good or service is because of inflation or other factors, such as an increase in the efficiency of factors of production, if inflation is high and volatile. An increase in inflation also leads to a decrease in the demand for money, as it reduces the incentive to hold money and increases transaction costs and shoe leather costs.

Monetary aggregates/money supply targeting

In the 1980s, several countries used an approach based on a constant growth in the money supply. This approach was refined to include different classes of money and credit (M0, M1 etc.). In the US this approach to monetary policy was discontinued with the selection of Alan Greenspan as Fed Chairman.

This approach is also sometimes called monetarism.

Central banks might choose to set a money supply growth target as a nominal anchor to keep prices stable in the long term. The quantity theory is a long run model, which links price levels to money supply and demand. Using this equation, we can rearrange to see the following:

π = μ − g,

where π is the inflation rate, μ is the money supply growth rate and g is the real output growth rate. This equation suggests that controlling the money supply’s growth rate can ultimately lead to price stability in the long run. To use this nominal anchor, a central bank would need to set μ equal to a constant and commit to maintaining this target.

However, targeting the money supply growth rate is considered a weak policy, because it is not stably related to the real output growth, As a result, a higher output growth rate will result in a too low level of inflation. A low output growth rate will result in inflation that would be higher than the desired level. [18]

While monetary policy typically focuses on a price signal of one form or another, this approach is focused on monetary quantities. As these quantities could have a role in the economy and business cycles depending on the households' risk aversion level, money is sometimes explicitly added in the central bank's reaction function. [20] After the 1980s, however, central banks have shifted away from policies that focus on money supply targeting, because of the uncertainty that real output growth introduces. Some central banks, like the ECB, have chosen to combine a money supply anchor with other targets.

Nominal income/NGDP targeting

Related to money targeting, nominal income targeting (also called Nominal GDP or NGDP targeting), originally proposed by James Meade (1978) and James Tobin (1980), was advocated by Scott Sumner and reinforced by the market monetarist school of thought.

Central banks do not implement this monetary policy explicitly. However, numerous studies shown that such a monetary policy targeting better matches welfare optimizing monetary policy compared to more standard monetary policy targeting. [21]

Fixed exchange rate targeting

This policy is based on maintaining a fixed exchange rate with a foreign currency. There are varying degrees of fixed exchange rates, which can be ranked in relation to how rigid the fixed exchange rate is with the anchor nation.

Under a system of fiat fixed rates, the local government or monetary authority declares a fixed exchange rate but does not actively buy or sell currency to maintain the rate. Instead, the rate is enforced by non-convertibility measures (e.g. capital controls, import/export licenses, etc.). In this case there is a black market exchange rate where the currency trades at its market/unofficial rate.

Under a system of fixed-convertibility, currency is bought and sold by the central bank or monetary authority on a daily basis to achieve the target exchange rate. This target rate may be a fixed level or a fixed band within which the exchange rate may fluctuate until the monetary authority intervenes to buy or sell as necessary to maintain the exchange rate within the band. (In this case, the fixed exchange rate with a fixed level can be seen as a special case of the fixed exchange rate with bands where the bands are set to zero.)

Under a system of fixed exchange rates maintained by a currency board every unit of local currency must be backed by a unit of foreign currency (correcting for the exchange rate). This ensures that the local monetary base does not inflate without being backed by hard currency and eliminates any worries about a run on the local currency by those wishing to convert the local currency to the hard (anchor) currency.

Under dollarization, foreign currency (usually the US dollar, hence the term "dollarization") is used freely as the medium of exchange either exclusively or in parallel with local currency. This outcome can come about because the local population has lost all faith in the local currency, or it may also be a policy of the government (usually to rein in inflation and import credible monetary policy).

Theoretically, using relative purchasing power parity (PPP), the rate of depreciation of the home country’s currency must equal the inflation differential:

rate of depreciation = home inflation rate – foreign inflation rate,

which implies that

home inflation rate = foreign inflation rate + rate of depreciation.

The anchor variable is the rate of depreciation. Therefore, the rate of inflation at home must equal the rate of inflation in the foreign country plus the rate of depreciation of the exchange rate of the home country currency, relative to the other.

With a strict fixed exchange rate or a peg, the rate of depreciation of the exchange rate is set equal to zero. In the case of a crawling peg, the rate of depreciation is set equal to a constant. With a limited flexible band, the rate of depreciation is allowed to fluctuate within a given range.

By fixing the rate of depreciation, PPP theory concludes that the home country’s inflation rate must depend on the foreign country‘s.

Countries may decide to use a fixed exchange rate monetary regime in order to take advantage of price stability and control inflation. In practice, more than half of nations’ monetary regimes use fixed exchange rate anchoring. [18]

These policies often abdicate monetary policy to the foreign monetary authority or government as monetary policy in the pegging nation must align with monetary policy in the anchor nation to maintain the exchange rate. The degree to which local monetary policy becomes dependent on the anchor nation depends on factors such as capital mobility, openness, credit channels and other economic factors.

In practice

Nominal anchors are possible with various exchange rate regimes.

Type of Nominal AnchorCompatible Exchange Rate Regimes
Exchange Rate TargetCurrency Union/Countries without own currency, Pegs/Bands/Crawls, Managed Floating
Money Supply TargetManaged Floating, Freely Floating
Inflation Target (+ Interest Rate Policy)Managed Floating, Freely Floating

Following the collapse of Bretton Woods, nominal anchoring has grown in importance for monetary policy makers and inflation reduction. Particularly, governments sought to use anchoring in order to curtail rapid and high inflation during the 1970s and 1980s. By the 1990s, countries began to explicitly set credible nominal anchors. In addition, many countries chose a mix of more than one target, as well as implicit targets. As a result, after the 1970s global inflation rates, on average, decreased gradually and central banks gained credibility and increasing independence.

The Global Financial Crisis of 2008 sparked controversy over the use and flexibility of inflation nominal anchoring. Many economists argued that inflation targets were set too low by many monetary regimes. During the crisis, many inflation-anchoring countries reached the lower bound of zero rates, resulting in inflation rates decreasing to almost zero or even deflation. [18]

Implications

The anchors discussed in this article suggest that keeping inflation at the desired level is feasible by setting a target interest rate, money supply growth rate, price level, or rate of depreciation. However, these anchors are only valid if a central bank commits to maintaining them. This, in turn, requires that the central bank abandon their monetary policy autonomy in the long run. Should a central bank use one of these anchors to maintain a target inflation rate, they would have to forfeit using other policies. Using these anchors may prove more complicated for certain exchange rate regimes. Freely floating or managed floating regimes have more options to affect their inflation, because they enjoy more flexibility than a pegged currency or a country without a currency. The latter regimes would have to implement an exchange rate target to influence their inflation, as none of the other instruments are available to them.

Credibility

The short-term effects of monetary policy can be influenced by the degree to which announcements of new policy are deemed credible. [22] In particular, when an anti-inflation policy is announced by a central bank, in the absence of credibility in the eyes of the public inflationary expectations will not drop, and the short-run effect of the announcement and a subsequent sustained anti-inflation policy is likely to be a combination of somewhat lower inflation and higher unemployment (see Phillips curve#NAIRU and rational expectations). But if the policy announcement is deemed credible, inflationary expectations will drop commensurately with the announced policy intent, and inflation is likely to come down more quickly and without so much of a cost in terms of unemployment.

Thus there can be an advantage to having the central bank be independent of the political authority, to shield it from the prospect of political pressure to reverse the direction of the policy. But even with a seemingly independent central bank, a central bank whose hands are not tied to the anti-inflation policy might be deemed as not fully credible; in this case there is an advantage to be had by the central bank being in some way bound to follow through on its policy pronouncements, lending it credibility.

Contexts

In international economics

Optimal monetary policy in international economics is concerned with the question of how monetary policy should be conducted in interdependent open economies. The classical view holds that international macroeconomic interdependence is only relevant if it affects domestic output gaps and inflation, and monetary policy prescriptions can abstract from openness without harm. [23] This view rests on two implicit assumptions: a high responsiveness of import prices to the exchange rate, i.e. producer currency pricing (PCP), and frictionless international financial markets supporting the efficiency of flexible price allocation. [24] [25] The violation or distortion of these assumptions found in empirical research is the subject of a substantial part of the international optimal monetary policy literature. The policy trade-offs specific to this international perspective are threefold: [26]

First, research suggests only a weak reflection of exchange rate movements in import prices, lending credibility to the opposed theory of local currency pricing (LCP). [27] The consequence is a departure from the classical view in the form of a trade-off between output gaps and misalignments in international relative prices, shifting monetary policy to CPI inflation control and real exchange rate stabilization.

Second, another specificity of international optimal monetary policy is the issue of strategic interactions and competitive devaluations, which is due to cross-border spillovers in quantities and prices. [28] Therein, the national authorities of different countries face incentives to manipulate the terms of trade to increase national welfare in the absence of international policy coordination. Even though the gains of international policy coordination might be small, such gains may become very relevant if balanced against incentives for international noncooperation. [24]

Third, open economies face policy trade-offs if asset market distortions prevent global efficient allocation. Even though the real exchange rate absorbs shocks in current and expected fundamentals, its adjustment does not necessarily result in a desirable allocation and may even exacerbate the misallocation of consumption and employment at both the domestic and global level. This is because, relative to the case of complete markets, both the Phillips curve and the loss function include a welfare-relevant measure of cross-country imbalances. Consequently, this results in domestic goals, e.g. output gaps or inflation, being traded-off against the stabilization of external variables such as the terms of trade or the demand gap. Hence, the optimal monetary policy in this case consists of redressing demand imbalances and/or correcting international relative prices at the cost of some inflation. [29]

Corsetti, Dedola and Leduc (2011) [26] summarize the status quo of research on international monetary policy prescriptions: "Optimal monetary policy thus should target a combination of inward-looking variables such as output gap and inflation, with currency misalignment and cross-country demand misallocation, by leaning against the wind of misaligned exchange rates and international imbalances." This is main factor in country money status.

In developing countries

Developing countries may have problems establishing an effective operating monetary policy. The primary difficulty is that few developing countries have deep markets in government debt. The matter is further complicated by the difficulties in forecasting money demand and fiscal pressure to levy the inflation tax by expanding the base rapidly. In general, the central banks in many developing countries have poor records in managing monetary policy. This is often because the monetary authorities in developing countries are mostly not independent of the government, so good monetary policy takes a backseat to the political desires of the government or is used to pursue other non-monetary goals. For this and other reasons, developing countries that want to establish credible monetary policy may institute a currency board or adopt dollarization. This can avoid interference from the government and may lead to the adoption of monetary policy as carried out in the anchor nation. Recent attempts at liberalizing and reform of financial markets (particularly the recapitalization of banks and other financial institutions in Nigeria and elsewhere) are gradually providing the latitude required to implement monetary policy frameworks by the relevant central banks.

Transparency

Beginning with New Zealand in 1990, central banks began adopting formal, public inflation targets with the goal of making the outcomes, if not the process, of monetary policy more transparent. In other words, a central bank may have an inflation target of 2% for a given year, and if inflation turns out to be 5%, then the central bank will typically have to submit an explanation. The Bank of England exemplifies both these trends. It became independent of government through the Bank of England Act 1998 and adopted an inflation target of 2.5% RPI, revised to 2% of CPI in 2003. [30] The success of inflation targeting in the United Kingdom has been attributed to the Bank of England's focus on transparency. [31] The Bank of England has been a leader in producing innovative ways of communicating information to the public, especially through its Inflation Report, which have been emulated by many other central banks. [32]

The European Central Bank adopted, in 1998, a definition of price stability within the Eurozone as inflation of under 2% HICP. In 2003, this was revised to inflation below, but close to, 2% over the medium term. Since then, the target of 2% has become common for other major central banks, including the Federal Reserve (since January 2012) and Bank of Japan (since January 2013). [33]

Effect on business cycles

There continues to be some debate about whether monetary policy can (or should) smooth business cycles. A central conjecture of Keynesian economics is that the central bank can stimulate aggregate demand in the short run, because a significant number of prices in the economy are fixed in the short run and firms will produce as many goods and services as are demanded (in the long run, however, money is neutral, as in the neoclassical model). However, some economists from the new classical school contend that central banks cannot affect business cycles. [34]

Behavioral monetary policy

Conventional macroeconomic models assume that all agents in an economy are fully rational. A rational agent has clear preferences, models uncertainty via expected values of variables or functions of variables, and always chooses to perform the action with the optimal expected outcome for itself among all feasible actions – they maximize their utility. Monetary policy analysis and decisions hence traditionally rely on this New Classical approach. [35] [36] [37] [38]

However, as studied by the field of behavioral economics that takes into account the concept of bounded rationality, people often deviate from the way that these neoclassical theories assume. [38] [39] Humans are generally not able to react fully rational to the world around them [37] – they do not make decisions in the rational way commonly envisioned in standard macroeconomic models. People have time limitations, cognitive biases, care about issues like fairness and equity and follow rules of thumb (heuristics). [39]

This has implications for the conduct of monetary policy. Monetary policy is the final outcome of a complex interaction between monetary institutions, central banker preferences and policy rules, and hence human decision-making plays an important role. [36] It is more and more recognized that the standard rational approach does not provide an optimal foundation for monetary policy actions. These models fail to address important human anomalies and behavioral drivers that explain monetary policy decisions. [40] [36] [37]

An example of a behavioral bias that characterizes the behavior of central bankers is loss aversion: for every monetary policy choice, losses loom larger than gains, and both are evaluated with respect to the status quo. [36] One result of loss aversion is that when gains and losses are symmetric or nearly so, risk aversion may set in. Loss aversion can be found in multiple contexts in monetary policy. The "hard fought" battle against the Great Inflation, for instance, might cause a bias against policies that risk greater inflation. [40] Another common finding in behavioral studies is that individuals regularly offer estimates of their own ability, competence, or judgments that far exceed an objective assessment: they are overconfident. Central bank policymakers may fall victim to overconfidence in managing the macroeconomy in terms of timing, magnitude, and even the qualitative impact of interventions. Overconfidence can result in actions of the central bank that are either "too little" or "too much". When policymakers believe their actions will have larger effects than objective analysis would indicate, this results in too little intervention. Overconfidence can, for instance, cause problems when relying on interest rates to gauge the stance of monetary policy: low rates might mean that policy is easy, but they could also signal a weak economy. [40]

These are examples of how behavioral phenomena may have a substantial influence on monetary policy. [38] Monetary policy analyses should thus account for the fact that policymakers (or central bankers) are individuals and prone to biases and temptations that can sensibly influence their ultimate choices in the setting of macroeconomic and/or interest rate targets. [36]

Central bank public institution that manages a states currency, money supply, and interest rates

A central bank, reserve bank, or monetary authority is an institution that manages the currency, money supply, and interest rates of a state or formal monetary union, and oversees their commercial banking system. In contrast to a commercial bank, a central bank possesses a monopoly on increasing the monetary base in the state, and also generally controls the printing/coining of the national currency, which serves as the state's legal tender. A central bank also acts as a lender of last resort to the banking sector during times of financial crisis. Most central banks also have supervisory and regulatory powers to ensure the solvency of member institutions, to prevent bank runs, and to discourage reckless or fraudulent behavior by member banks.

Money supply total amount of monetary assets available in an economy at a specific time


The money supply is the total value of money available in an economy at a point of time. There are several ways to define "money", but standard measures usually include currency in circulation and demand deposits. Each country’s central bank may use its own definitions of what constitutes money for its purposes.

Economic policy refers to the actions that governments take in the economic field

The economic policy of governments covers the systems for setting levels of taxation, government budgets, the money supply and interest rates as well as the labour market, national ownership, and many other areas of government interventions into the economy.

In modern monetary policy, a devaluation is an official lowering of the value of a country's currency within a fixed exchange-rate system, in which a monetary authority formally sets a lower exchange rate of the national currency in relation to a foreign reference currency or currency basket. The opposite of devaluation, a change in the exchange rate making the domestic currency more expensive, is called a revaluation. A monetary authority maintains a fixed value of its currency by being ready to buy or sell foreign currency with the domestic currency at a stated rate; a devaluation is an indication that the monetary authority will buy and sell foreign currency at a lower rate.

An open market operation (OMO) is an activity by a central bank to give liquidity in its currency to a bank or a group of banks. The central bank can either buy or sell government bonds in the open market or, in what is now mostly the preferred solution, enter into a repo or secured lending transaction with a commercial bank: the central bank gives the money as a deposit for a defined period and synchronously takes an eligible asset as collateral. A central bank uses OMO as the primary means of implementing monetary policy. The usual aim of open market operations is—aside from supplying commercial banks with liquidity and sometimes taking surplus liquidity from commercial banks—to manipulate the short-term interest rate and the supply of base money in an economy, and thus indirectly control the total money supply, in effect expanding money or contracting the money supply. This involves meeting the demand of base money at the target interest rate by buying and selling government securities, or other financial instruments. Monetary targets, such as inflation, interest rates, or exchange rates, are used to guide this implementation.

Impossible trinity

The impossible trinity is a concept in international economics which states that it is impossible to have all three of the following at the same time:

Floating exchange rate

A floating exchange rate is a type of exchange rate regime in which a currency's value is allowed to fluctuate in response to foreign exchange market events. A currency that uses a floating exchange rate is known as a floating currency. A floating currency is contrasted with a fixed currency whose value is tied to that of another currency, material goods or to a currency basket.

Inflation targeting is a monetary policy where a central bank follows an explicit target for the inflation rate for the medium-term and announces this inflation target to the public. The assumption is that the best that monetary policy can do to support long-term growth of the economy is to maintain price stability. The central bank uses interest rates, its main short-term monetary instrument.

Central Bank of Chile the central bank of Chile

The Central Bank of Chile is the central bank of Chile. It was originally created in 1925 and is incorporated into the current Chilean Constitution as an autonomous institution of constitutional rank. Its monetary policy is currently guided by an inflation targeting regime.

Monetary inflation is a sustained increase in the money supply of a country. Depending on many factors, especially public expectations, the fundamental state and development of the economy, and the transmission mechanism, it is likely to result in price inflation, which is usually just called "inflation", which is a rise in the general level of prices of goods and services.

Currency intervention monetary policy operation

Currency intervention, also known as foreign exchange market intervention or currency manipulation, is a monetary policy operation. It occurs when a government or central bank buys or sells foreign currency in exchange for their own domestic currency, generally with the intention of influencing the exchange rate and trade policy.

A fixed exchange rate, sometimes called a pegged exchange rate, is a type of exchange rate regime in which a currency's value is fixed or pegged by a monetary authority against the value of another currency, a basket of other currencies, or another measure of value, such as gold.

A flexible exchange-rate system is a monetary system that allows the exchange rate to be determined by supply and demand.

Sterilization (economics) economic action taken by a central bank

In macroeconomics, sterilization is action taken by a country's central bank to counter the effects on the money supply caused by a balance of payments surplus or deficit. This can involve open market operations undertaken by the central bank whose aim is to neutralize the impact of associated foreign exchange operations. The opposite is unsterilized intervention, where monetary authorities have not insulated their country's domestic money supply and internal balance against foreign exchange intervention.

Monetary policy is the monitoring and control of money supply by a central bank, such as the Federal Reserve Board in the United States of America, and the Bangko Sentral ng Pilipinas in the Philippines. This is used by the government to be able to control inflation, and stabilize currency. Monetary Policy is considered to be one of the two ways that the government can influence the economy – the other one being Fiscal Policy. Monetary Policy is generally the process by which the central bank, or government controls the supply and availability of money, the cost of money, and the rate of interest.

Fear of floating refers to situations where a country prefers a fixed exchange rate to a floating exchange rate regime. This is more relevant in emerging economies, especially when they suffered from financial crisis in last two decades. In foreign exchange markets of the emerging market economies, there is evidence showing that countries who claim they are floating their currency, are actually reluctant to let the nominal exchange rate fluctuate in response to macroeconomic shocks. In the literature, this is first convincingly documented by Calvo and Reinhart with "fear of floating" as the title of one of their papers in 2000. Since then, this widespread phenomenon of reluctance to adjust exchange rates in emerging markets is usually called "fear of floating". Most of the studies on "fear of floating" are closely related to literature on costs and benefits of different exchange rate regimes.

A distributional effect is the effect of the redistribution of the final gains and costs derived from the direct gains and cost allocations of a project. A project has a direct-profit redistribution effect and a direct-cost redistribution effect. But whether it is profit or cost, the redistribution effect can be expressed as a benefit to a group of people or department or region, and the loss to another party. In theory, the indirect profit and indirect costs can also be derived from the redistribution effect, and valued.
