Standardized approach (counterparty credit risk)

Last updated

The standardized approach for counterparty credit risk (SA-CCR) is the capital requirement framework under Basel III addressing counterparty risk for derivative trades. [1] It was published by the Basel Committee in March 2014. [2] See Basel III: Finalising post-crisis reforms.

The framework replaced both non-internal model approaches: the Current Exposure Method (CEM) and the Standardised Method (SM). It is intended to be a "risk-sensitive methodology", i.e. conscious of asset class and hedging, that differentiates between margined and non-margined trades and recognizes netting benefits; considerations insufficiently addressed under the preceding frameworks.

SA-CCR calculates the exposure at default of derivatives and "long-settlement transactions" exposed to counterparty credit risk. It builds EAD as (i) a "Replacement Cost" (RC), were the counterparty to default today; combined with (ii) the "Potential Future Exposure" (PFE) to the counterparty. For the former: current exposure, i.e. mark-to-market of the trades, is aggregated by counterparty, and then netted-off with haircutted- collateral. For the latter: per asset class, trade "add-ons", as reduced by offsetting based on correlation assumptions, are aggregated to "hedging sets"; these are then aggregated to "netting sets", and offset by the counterparty's collateral (i.e. initial margin), which is subject to a "multiplier" that limits its benefit and applies a 5% floor to the exposure.

The SA-CCR EAD is an input to the bank's regulatory capital calculation where it is combined with the counterparty's PD and LGD to derive RWA; Some banks thus incorporate SA-CCR into their KVA calculations. Because of its two-step aggregation, capital allocation between trading desks (or even asset classes) is challenging; thus making it difficult to fairly calculate each desk's risk-adjusted return on capital. Various methods are then proposed here. [3] SA-CCR is also input to other regulations such as the leverage ratio and the net stable funding ratio.

In finance, a derivative is a contract that derives its value from the performance of an underlying entity. This underlying entity can be an asset, index, or interest rate, and is often simply called the underlying. Derivatives can be used for a number of purposes, including insuring against price movements (hedging), increasing exposure to price movements for speculation, or getting access to otherwise hard-to-trade assets or markets.

In finance, an interest rate swap (IRS) is an interest rate derivative (IRD). It involves exchange of interest rates between two parties. In particular it is a "linear" IRD and one of the most liquid, benchmark products. It has associations with forward rate agreements (FRAs), and with zero coupon swaps (ZCSs).

A credit default swap (CDS) is a financial swap agreement that the seller of the CDS will compensate the buyer in the event of a debt default or other credit event. That is, the seller of the CDS insures the buyer against some reference asset defaulting. The buyer of the CDS makes a series of payments to the seller and, in exchange, may expect to receive a payoff if the asset defaults.

Credit risk is the possibility of losing a lender holds due to a risk of default on a debt that may arise from a borrower failing to make required payments. In the first resort, the risk is that of the lender and includes lost principal and interest, disruption to cash flows, and increased collection costs. The loss may be complete or partial. In an efficient market, higher levels of credit risk will be associated with higher borrowing costs. Because of this, measures of borrowing costs such as yield spreads can be used to infer credit risk levels based on assessments by market participants.

Over-the-counter (OTC) or off-exchange trading or pink sheet trading is done directly between two parties, without the supervision of an exchange. It is contrasted with exchange trading, which occurs via exchanges. A stock exchange has the benefit of facilitating liquidity, providing transparency, and maintaining the current market price. In an OTC trade, the price is not necessarily publicly disclosed.

The Basel Accords refer to the banking supervision accords issued by the Basel Committee on Banking Supervision (BCBS).

Financial risk management is the practice of protecting economic value in a firm by managing exposure to financial risk - principally operational risk, credit risk and market risk, with more specific variants as listed aside. As for risk management more generally, financial risk management requires identifying the sources of risk, measuring these, and crafting plans to mitigate them. See Finance § Risk management for an overview.

The term Advanced IRB or A-IRB is an abbreviation of advanced internal ratings-based approach, and it refers to a set of credit risk measurement techniques proposed under Basel II capital adequacy rules for banking institutions.

Probability of default (PD) is a financial term describing the likelihood of a default over a particular time horizon. It provides an estimate of the likelihood that a borrower will be unable to meet its debt obligations.

Loss given default or LGD is the share of an asset that is lost if a borrower defaults.

Exposure at default or (EAD) is a parameter used in the calculation of economic capital or regulatory capital under Basel II for a banking institution. It can be defined as the gross exposure under a facility upon default of an obligor.

A central clearing counterparty (CCP), also referred to as a central counterparty, is a financial institution that takes on counterparty credit risk between parties to a transaction and provides clearing and settlement services for trades in foreign exchange, securities, options, and derivative contracts. CCPs are highly regulated institutions that specialize in managing counterparty credit risk.

Collateral has been used for hundreds of years to provide security against the possibility of payment default by the opposing party in a trade. Collateral management began in the 1980s, with Bankers Trust and Salomon Brothers taking collateral against credit exposure. There were no legal standards, and most calculations were performed manually on spreadsheets. Collateralisation of derivatives exposures became widespread in the early 1990s. Standardisation began in 1994 via the first ISDA documentation.

A Credit valuation adjustment (CVA), in financial mathematics, is an "adjustment" to a derivative's price, as charged by a bank to a counterparty to compensate it for taking on the credit risk of that counterparty during the life of the transaction. CVA is one of a family of related valuation adjustments, collectively xVA; for further context here see Financial economics § Derivative pricing. "CVA" can refer more generally to several related concepts, as delineated aside.

Basel III is the third Basel Accord, a framework that sets international standards for bank capital adequacy, stress testing, and liquidity requirements. Augmenting and superseding parts of the Basel II standards, it was developed in response to the deficiencies in financial regulation revealed by the financial crisis of 2007–08. It is intended to strengthen bank capital requirements by increasing minimum capital requirements, holdings of high quality liquid assets, and decreasing bank leverage.

The ISDA Master Agreement, published by the International Swaps and Derivatives Association, is the most commonly used master service agreement for OTC derivatives transactions internationally. It is part of a framework of documents, designed to enable OTC derivatives to be documented fully and flexibly. The framework consists of a master agreement, a schedule, confirmations, definition booklets, and credit support documentation.

Under the Basel II guidelines, banks are allowed to use their own estimated risk parameters for the purpose of calculating regulatory capital. This is known as the internal ratings-based (IRB) approach to capital requirements for credit risk. Only banks meeting certain minimum conditions, disclosure requirements and approval from their national supervisor are allowed to use this approach in estimating capital for various exposures.

Basel III: Finalising post-crisis reforms, sometimes called the Basel III Endgame, Basel 3.1 or Basel IV, are changes to international standards for bank capital requirements that were agreed by the Basel Committee on Banking Supervision (BCBS) in 2017 and are due for implementation in January 2023. They amend the international banking standards known as the Basel Accords.

An X-Value Adjustment is an umbrella term referring to a number of different “valuation adjustments” that banks must make when assessing the value of derivative contracts that they have entered into. The purpose of these is twofold: primarily to hedge for possible losses due to other parties' failures to pay amounts due on the derivative contracts; but also to determine the amount of capital required under the bank capital adequacy rules. XVA has led to the creation of specialized desks in many banking institutions to manage XVA exposures.

In finance, a zero coupon swap (ZCS) is an interest rate derivative (IRD). In particular it is a linear IRD, that in its specification is very similar to the much more widely traded interest rate swap (IRS).
