On September 17, 2019, interest rates on overnight repurchase agreements (or "repos"), which are short-term loans between financial institutions, experienced a sudden and unexpected spike. A measure of the interest rate on overnight repos in the United States, the Secured Overnight Financing Rate (SOFR), increased from 2.43 percent on September 16 to 5.25 percent on September 17. During the trading day, interest rates reached as high as 10 percent. The activity also affected the interest rates on unsecured loans between financial institutions, and the Effective Federal Funds Rate (EFFR), which serves as a measure for such interest rates, moved above its target range determined by the Federal Reserve.
This activity prompted an emergency intervention by the Federal Reserve Bank of New York, which injected $75 billion in liquidity into the repo markets on September 17 and continued to do so every morning for the rest of the week. On September 19, the Federal Reserve's Federal Open Market Committee also lowered the interest paid on bank reserves. These actions were ultimately successful in calming the markets and, by September 20, rates had returned to a stable level. The Federal Reserve Bank of New York continued to regularly provide liquidity to the repo market until June 2020.
The causes of the rate spike were not immediately clear. Economists later identified its main cause to be a temporary shortage of cash available in the financial system, which was itself caused by two events taking place on September 16: the deadline for the payment of quarterly corporate taxes and the issuing of new Treasury securities. The effects of this temporary shortage were exacerbated by declining level of reserves in the banking system. Other contributing factors have been suggested by economists and observers.
Banks and financial institutions analyze their cash reserves on a daily basis, and assess whether they have an excess or a deficit of cash with respect to their needs. Banks that do not have sufficient cash to meet their liquidity needs borrow it from banks and money market funds with excess cash. This type of lending generally takes place overnight, which means that the cash is repaid the next day. [1] [2] [3]
Repurchase agreements, commonly referred to as repos, are a type of loans that are collateralized by securities and are generally provided for a short period of time. [4] [5] Although repos are economically equivalent to secured loans, they are legally structured as a sale and subsequent repurchase of securities. [1] [6] There are two steps in a repo transaction. First, the borrower sells their securities to the lender and receives cash in exchange. Second, the borrower repurchases the securities from the lender by repaying the cash amount they received plus an additional amount, which is the interest. [5] [7] This structure allows lenders to provide loans with very little risk, [5] [8] [9] and borrowers to borrow at low rates. [9]
The repo market is used by banks, financial institutions and institutional investors to borrow cash to meet their overnight liquidity needs [5] [10] [11] or to finance positions in the market. [12] In this context, the repurchased securities are most often Treasury securities, [5] [9] but can also be agency securities [lower-alpha 1] and mortgage-backed securities. [14] The broad measure of the interest rate for overnight loans collateralized by Treasury securities is the Secured Overnight Financing Rate (SOFR), which is administered by the Federal Reserve Bank of New York. [15] The daily volume of repo transactions is generally estimated to be around $1 trillion; hence, according to economists at the Bank for International Settlements, "any sustained disruption in this market [...] could quickly ripple through the financial system". [16]
The U.S. repo market is broadly divided into two segments: the tri-party market and the bilateral market. The tri-party market involves large, high-quality dealers borrowing cash from money market funds. This segment is called "tri-party" because a third party, the bank BNY Mellon, provides various services to market participants. The bilateral market involves large dealers lending to borrowers, such as smaller dealers and hedge funds. A common practice is for dealers to borrow cash on the tri-party market to lend it to their clients on the bilateral market. [17] [18]
Federal funds are funds that are loaned or borrowed by financial institutions overnight to meet their liquidity needs. Unlike repos, federal funds are unsecured. [19] [20] According to economist Frederic Mishkin and finance professor Stanley Eakins, the term "federal funds" is misleading: "federal funds have nothing to do with the federal government", and "[t]he term comes from the fact that these funds are held at the Federal Reserve bank". [19] The repo market and the federal funds market are theoretically separate. However, there are significant links and interactions between the two, and shocks in one market can transmit themselves to the other. [21]
The interest rate on federal funds is an important component of U.S. monetary policy. [3] [20] To implement its monetary policy, the Federal Reserve's Federal Open Market Committee determines a target range for the federal funds rate. [3] [20] Although the Federal Reserve cannot directly control the rate, which is primarily determined by the forces of supply and demand, [1] it can influence it by adjusting the interest rate on reserve balances held by banks at the Federal Reserve, [3] or by buying (or selling) securities from (or to) banks. [1] The measure of the interest rate on federal funds is the Effective Federal Funds Rate (EFFR), which is calculated as the effective median interest rate of overnight federal funds transactions on any business day. It is published by the Federal Reserve Bank of New York. [1] [22]
Before September 2019, both the SOFR and the EFFR were quite stable. [16] [17] The EFFR had remained within the FOMC's target range on all but one day since 2015. The SOFR was slightly more volatile, especially around quarter-end reporting dates, but had rarely moved more than 0.2 percentage points on a single day. [2] [17] On Monday, September 16, the SOFR was at 2.43 percent, an increase of 0.13 percentage points compared to the previous business day (Friday, September 13). The EFFR was at 2.25 percent, an increase of 0.11 percentage points from September 13. [17] The EFFR was trading at the upper limit of the Federal Reserve's target range, which was 2 to 2.25 percent. [2] [23]
On the morning [2] of Tuesday, September 17, interest rates on overnight repo transactions experienced a sudden and unexpected [2] [17] [24] increase. [2] [25] During the trading day, interest rates on overnight repo transactions went as high as 10 percent, [25] [26] with the top 1 percent of transactions reaching 9 percent. [17] [24] The SOFR benchmark increased by 2.3 percentage points and reached 5.25 percent for the day. [15] [27] The strains in the repo market quickly spilled into the federal funds market, [2] [17] and the EFFR moved above the top of its target range, to 2.3 percent. [17] [24]
Beginning on the morning of Tuesday, September 17, the Federal Reserve Bank of New York (or New York Fed) began to take action to restore market stability. Shortly after 9 a.m., it announced that it would begin to lend cash to borrowers on the repo market, in an amount of up to $75 billion. [2] [17] [28] The New York Fed would accept as collateral Treasury securities, agency debt securities and agency mortgage-backed securities. [2] [17] [28] Interest rates began to decrease shortly after the announcement. [17] [28] Most repo trading occurs early in the morning, and had therefore taken place before the New York Fed's announcement: as a result, only $53 billion was borrowed from the New York Fed by market participants. [17] [28] [lower-alpha 2]
On the afternoon of September 17, repo rates remained relatively elevated, since market participants were uncertain whether the New York Fed would continue its intervention on the following days. These concerns were alleviated when the New York Fed announced at 8:15 a.m. the following morning (Wednesday, September 18) that it would conduct a second $75 billion overnight lending operation. [28] Repo rates then stabilized and federal funds rates returned closer to the Federal Reserve's target range. [2] [17]
On September 19, the Federal Open Market Committee lowered the interest rate paid on reserves balances held by banks, in an effort to lower the EFFR, which tends to trade slightly above the rate paid on bank reserves. [2] [17] This decision also reduced the chance that the EFFR would return to levels above the Federal Reserve's target range. [17] Meanwhile, the New York Fed continued to lend a daily amount of $75 billion overnight to market participants every morning of the week, through Friday, September 20. [17] [29] All three operations were fully subscribed. [lower-alpha 3] [17] On September 20, the New York Fed announced that it would continue to perform daily overnight operations through October 10. [17] [29]
The actions of the Federal Reserve and the New York Fed were successful in calming the market activity: by September 20, the rates on overnight repo transactions had sunk to 1.75 percent [31] and the rates on federal reserve funds decreased to 1.9 percent. [32]
The New York Fed continued to offer liquidity to market participants for several months, in an effort to control and limit volatility. [33] In June 2020, the New York Fed tightened its operations on the repo market, after seeing "substantial improvement" in market condition. [34] [35] From June 2020, market participants stopped using the Fed's liquidity facility. [36] In January 2021, the New York Fed discontinued its repo facility altogether, citing a "sustained smooth functioning" of the market. [36]
The cause of September 2019 market events was not immediately clear, [5] with The Wall Street Journal characterizing the event as a "mystery". [23] Over time, market observers and economists have suggested a combination of several factors as the causes of the rates hike. [5] [12]
Two developments took place in mid-September that reduced the amount of cash available in the system and thus put stress on the overnight funding market. [2] [17] [37]
Firstly, quarterly corporate taxes were due on September 16, 2019. As a result, a substantial amount of cash was withdrawn from clients' accounts and was paid to the Treasury. Over a period of a few days, taxpayers withdrew more than $100 billion out of the banking system and money market funds to pay their taxes. [lower-alpha 4] [2] [17] This reduced the amount of cash available in the system and, specifically, in the repo market, since banks and money market funds generally lend their excess cash in the repo market. [2] [17] [39]
Secondly, new Treasury securities were settled on September 16, meaning that their price was paid by their purchasers on this date. [17] [39] The total amount paid by buyers in exchange for Treasury securities was $54 billion, [2] [17] which was withdrawn from their bank and money markets accounts. [2] However, "[a] substantial share of newly issued Treasury debt is typically purchased by securities dealers, who then gradually sell the bonds to their customers." [2] Between the moment dealers purchase newly issued Treasury securities and the moment they are able to sell them to customers, they finance their purchase by lending the securities on the repo market. [2] [17] [39] Thus, there were more Treasury securities to be financed in the market on September 16, but less cash available to borrowers to purchase them. [2] [17] [39]
As a result, the increased rate for overnight funding seemed to stem from a temporary increase in the demand for cash and a simultaneous, temporary decline in the supply of cash, [2] [17] [39] leading to a shortage of cash available in the system. [5] [23] [40]
The temporary cash shortage is nevertheless insufficient to explain the intensity of the movements observed in September 2019. The effects of the temporary cash shortage seemed to have been exacerbated by broader market trends. [2] [16] [17] [41]
The events of September 2019 have been associated with the declining level of reserves in the banking system. [2] [17] [41] "Reserves", in this context, means the cash held by banks in accounts at the central bank. The main function of reserves is for banks to make payments to each other, generally as a way to settle transactions that have taken place between their customers. Reserves can be increased by government spending, which results in cash being transferred from government accounts to bank accounts. [42] By contrast, the government can decrease reserves by selling government bonds, such as Treasury securities, to investors, which results in cash being transferred from bank accounts (and thus reserves) to government accounts. [37] [42] [43]
During and after the financial crisis of 2007–2008, the Federal Reserve stimulated the economy by purchasing trillions of dollars of Treasury securities and mortgage-backed securities from banks and investors. As a result, reserves increased from around $10 billion at the end of 2007 to a peak of $2.8 trillion in 2014. [2] [17] [44] In October 2017, the Federal Reserve began to reduce the size of its assets, [2] [17] [41] most notably by stopping its purchases of Treasury securities and by letting its existing stock of Treasuries expire. [42] [45] As a result, reserves began to decline gradually, [2] [17] [41] and financial institutions began to hold an increasing amount of Treasury securities themselves. [17] [42] According to economists at the Bank for International Settlement, this trend was particularly pronounced in the four main banks that are active as lenders in the repo market: since 2018, their holdings of liquid assets became increasingly skewed towards Treasury securities, which made it more difficult for them to lend their cash when demand rises. [16] [46]
In mid-September 2019, the supply of reserves in the banking system amounted to $1.4 trillion, their lowest point since 2011. [17] [47] Economists and analysts have suggested that such a low amount of reserves may have exacerbated the liquidity shortage experienced on September 17. [2] [17] [42] [48]
According to Jamie Dimon, the CEO of JP Morgan, the bank had the cash and the willingness to deploy liquidity in the repo markets but was prevented from doing so by regulations on bank liquidity. [49] Liquidity regulations require banks to hold a stock of liquid assets (such as cash) at all times to survive crisis scenarios, such as bank runs. [50]
Some economists have acknowledged that liquidity regulations may have prevented banks from lending more cash on the repo markets in September 2019, thus contributing to the cash shortage. [51] [lower-alpha 5] Other researchers have taken a different view. They have argued that the inability of banks to deploy liquidity quickly to profit from the high rates was not caused by the liquidity regulations themselves, but by the more prudent risk-management framework put in place by banks after the 2007-08 crisis. [52] They have also pointed out that other significant lenders on the repo market, such as money market funds and pension funds, were similarly reluctant to lend in mid-September 2019, despite not being subject to banking regulations. [17]
Economists and market observers have suggested other factors as possible causes of the mid-September spike:
The Federal Reserve System is the central banking system of the United States. It was created on December 23, 1913, with the enactment of the Federal Reserve Act, after a series of financial panics led to the desire for central control of the monetary system in order to alleviate financial crises. Over the years, events such as the Great Depression in the 1930s and the Great Recession during the 2000s have led to the expansion of the roles and responsibilities of the Federal Reserve System.
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.
The monetary policy of The United States is the set of policies which the Federal Reserve follows to achieve its twin objectives of high employment and stable inflation.
The money market is a component of the economy that provides short-term funds. The money market deals in short-term loans, generally for a period of a year or less.
A repurchase agreement, also known as a repo, RP, or sale and repurchase agreement, is a form of short-term borrowing, mainly in government securities. The dealer sells the underlying security to investors and, by agreement between the two parties, buys them back shortly afterwards, usually the following day, at a slightly higher price.
In macroeconomics, 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.
In the United States, the federal funds rate is the interest rate at which depository institutions lend reserve balances to other depository institutions overnight on an uncollateralized basis. Reserve balances are amounts held at the Federal Reserve. Institutions with surplus balances in their accounts lend those balances to institutions in need of larger balances. The federal funds rate is an important benchmark in financial markets and central to the conduct of monetary policy in the United States as it influences a wide range of market interest rates.
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.
The discount window is an instrument of monetary policy that allows eligible institutions to borrow money from the central bank, usually on a short-term basis, to meet temporary shortages of liquidity caused by internal or external disruptions.
Bank rate, also known as discount rate in American English, is the rate of interest which a central bank charges on its loans and advances to a commercial bank. The bank rate is known by a number of different terms depending on the country, and has changed over time in some countries as the mechanisms used to manage the rate have changed.
The overnight rate is generally the interest rate that large banks use to borrow and lend from one another in the overnight market. In some countries, the overnight rate may be the rate targeted by the central bank to influence monetary policy. In most countries, the central bank is also a participant on the overnight lending market, and will lend or borrow money to some group of banks.
The Term Auction Facility (TAF) was a temporary program managed by the United States Federal Reserve designed to "address elevated pressures in short-term funding markets." Under the program the Fed auctions collateralized loans with terms of 28 and 84 days to depository institutions that are "in generally sound financial condition" and "are expected to remain so over the terms of TAF loans." Eligible collateral is the same as that accepted for discount window loans and includes a wide range of financial assets. The program was instituted in December 2007 in response to problems associated with the subprime mortgage crisis and was motivated by a desire to address a widening spread between interest rates on overnight and term interbank lending, indicating a retreat from risk-taking by banks. The action was in coordination with simultaneous and similar initiatives undertaken by the Bank of Canada, the Bank of England, the European Central Bank and the Swiss National Bank.
On March 17, 2008, in response to the subprime mortgage crisis and the collapse of Bear Stearns, the Federal Reserve announced the creation of a new lending facility, the Primary Dealer Credit Facility (PDCF). Eligible borrowers include all financial institutions listed as primary dealers, and the term of the loan is a repurchase agreement, or "repo" loan, whereby the broker dealer sells a security in exchange for funds through the Fed's discount window. The security in question acts as collateral, and the Federal Reserve charges an interest rate equivalent to the Fed's primary credit rate. The facility was intended to improve the ability of broker dealers to access liquidity in the overnight loan market that banks use to meet their reserve requirements.
The Term Securities Lending Facility (TSLF) was a 28-day facility managed by the United States Federal Reserve offering Treasury general collateral (GC) to the primary dealers in exchange for other program-eligible collateral. It was created to combat the liquidity crisis in American banks that had begun in late 2007, part of the broader financial crisis of 2007-2008. The facility was open from March 2008 through January 2010.
The U.S. central banking system, the Federal Reserve, in partnership with central banks around the world, took several steps to address the subprime mortgage crisis. Federal Reserve Chairman Ben Bernanke stated in early 2008: "Broadly, the Federal Reserve’s response has followed two tracks: efforts to support market liquidity and functioning and the pursuit of our macroeconomic objectives through monetary policy." A 2011 study by the Government Accountability Office found that "on numerous occasions in 2008 and 2009, the Federal Reserve Board invoked emergency authority under the Federal Reserve Act of 1913 to authorize new broad-based programs and financial assistance to individual institutions to stabilize financial markets. Loans outstanding for the emergency programs peaked at more than $1 trillion in late 2008."
An overnight indexed swap (OIS) is an interest rate swap (IRS) over some given term, e.g. 10Y, where the periodic fixed payments are tied to a given fixed rate while the periodic floating payments are tied to a floating rate calculated from a daily compounded overnight rate over the floating coupon period. Note that the OIS term is not overnight; it is the underlying reference rate that is an overnight rate. The exact compounding formula depends on the type of such overnight rate.
The interbank lending market is a market in which banks lend funds to one another for a specified term. Most interbank loans are for maturities of one week or less, the majority being overnight. Such loans are made at the interbank rate. A sharp decline in transaction volume in this market was a major contributing factor to the collapse of several financial institutions during the financial crisis of 2007–2008.
The overnight market is the component of the money market involving the shortest term loan. The overnight market is primarily used by banks and other financial institutions. Lenders agree to lend borrowers funds only "overnight" i.e. the borrower must repay the borrowed funds plus interest at the start of business the next day. Given the short period of the loan, the interest rate charged in the overnight market, known as the overnight rate is, generally speaking, the lowest rate at which banks lend money.
Central bank liquidity swap is a type of currency swap used by a country's central bank to provide liquidity of its currency to another country's central bank. In a liquidity swap, the lending central bank uses its currency to buy the currency of another borrowing central bank at the market exchange rate, and agrees to sell the borrower's currency back at a rate that reflects the interest accrued on the loan. The borrower's currency serves as collateral.
Secured Overnight Financing Rate (SOFR) is a secured overnight interest rate. SOFR is a reference rate established as an alternative to LIBOR. LIBOR had been published in a number of currencies and underpins financial contracts all over the world. Deeming it prone to manipulation, UK regulators decided to discontinue LIBOR in 2021.
