Risk Weighted Assets - Basel III sets guidelines
Risk-weighted assets are used to determine the minimum amount of capital that must be held by banks and other financial institutions in order to reduce the risk of insolvency. The capital requirement is based on a risk assessment for each type of bank asset.
Risk-weighted assets are used to determine the minimum amount of regulatory capital that must be held by banks to maintain their solvency. This minimum is based on a risk assessment for each type of bank risk exposure: credit, market, operational, counterparty and credit valuation adjustment risks. The riskier the asset, the higher the RWAs and the greater the amount of regulatory capital required.

capital charges
An amount of money equal to how much a business has tied up in assets multiplied by the weighted average cost of those assets. The computation of the economic profit of a business by its finance department involves subtracting its capital charge from its net operating profit.

company’s weighted average cost of capital (WACC)
Average interest rate a company must pay to finance its assets.
term repo
Under a term repurchase agreement (term repo), a bank will agree to buy securities from a dealer and then resell them back to the dealer a short time later at a pre-specified price. The difference between the re-purchase and sale prices represents the implicit interest paid for the agreement.
on-the-run
On-the-run Treasuries are the most recently issued U.S. Treasury bonds or notes of a particular maturity. On-the-run Treasuries are the opposite of “off-the-run” Treasuries, which refer to Treasury securities that have been issued before the most recent issue and are still outstanding. Media mentions about Treasury yields and prices generally reference on-the-run Treasuries.
If another set of Treasury notes get issued in the next month, those become the new on-the-run Treasuries, and the previously issued Treasuries are considered off-the-run. This cycle continues as each new batch is created, with every group other than the newest run deemed off-the-run for the rest of its associated time, until it is cashed in upon reaching maturity.
The most actively traded Treasuries at any point in time are those that are considered on-the-run. Due to the increased activity, they tend to have a higher initial cost and lower yield than off-the-run notes. This causes on-the-run Treasuries to be more liquid, as finding a buyer tends to be simpler than off-the-run options. This leads to more investments relating to hedging than to longer-term investments.
initial + variation margin payments
Variation margin – the other type of collateral – is paid daily from one side of the trade to the other, to reflect the current market value of the trade. Initial margin is held to cover the losses that could arise in the period between the defaulter’s last variation margin payment and the point at which the surviving party is able to hedge or replace the trade.
In cleared trades, this period is set at anywhere from five to seven days – so initial margin on a large portfolio can become a very significant commitment.
IM is posted when the trade is executed and then adjusted as necessary throughout the life of the trade. For centrally cleared trades, counterparties post IM to the clearing house; in non-cleared trades, to each other. It is usually posted in cash, government bonds or letters of credit.
bank’s risk-weighted capital buffer
A capital buffer is mandatory capital that financial institutions are required to hold in addition to other minimum capital requirements. Regulations targeting the creation of adequate capital buffers are designed to reduce the procyclical nature of lending by promoting the creation of countercyclical buffers as set forth in the Basel III regulatory reforms created by the Basel Committee on Banking Supervision.
Note that capital buffers differ from, and may exceed the reserve requirements set by the central bank.

In December 2010, the Basel Committee on Banking Supervision released official regulatory standards for the purpose of creating a more resilient global banking system, particularly when addressing issues of liquidity. Capital buffers identified in Basel III reforms include countercyclical capital buffers, which are determined by Basel Committee member jurisdictions and vary according to a percentage of risk-weighted assets, and capital conservation buffers, which are built up outside periods of financial stress.
LEVERAGE RATIO
The Basel III Tier 1 leverage ratio, first introduced in 2009, is a capital adequacy tool that measures a bank’s Tier 1 capital divided by its total exposures, including average consolidated assets, derivatives exposures and off-balance sheet items. Regulators and policy-makers believe that an underlying cause of the 2008 financial crisis was excessive leverage in the banking system, and so the intent behind the Basel III leverage ratio is to constrain the degree to which the bank can leverage its capital and improve the extent to which it can sustain negative shocks to its balance sheet.
The Basel standards require banks to maintain a Tier 1 leverage ratio of at least 3%. Global systemically important banks should maintain an extra leverage ratio buffer, which the Basel Committee agreed in December 2017 to set at 50% of a bank’s risk-weighted capital buffer.
National regulators have implemented their own versions of the Basel III leverage ratio in their respective jurisdictions. As the methodology does not take into account the risk weighting of specific assets, banks say it punishes certain businesses like clearing – where the real risks are offset by client margin held – or assets held at the central bank that are theoretically riskless.
However, many regulators consider a risk-insensitive leverage ratio an essential complement to the risk-based capital ratios that also form part of capital adequacy regimes. Regulators say one of the lessons of the crisis was that risk-weighted measures can misrepresent a bank’s actual safety and soundness, and so the leverage ratio is a necessary “backstop”.
supplementary leverage ratio (SLR)
The supplementary leverage ratio is the US implementation of the Basel III Tier 1 leverage ratio, with which banks calculate the amount of common equity capital they must hold relative to their total leverage exposure. Large US banks must hold 3%. Top-tier bank holding companies must also hold an extra 2% buffer, for a total of 5%. The SLR, which does not distinguish between assets based on risk, is conceived as a backstop to risk-weighted capital requirements.
financial backstop
A term used in the financial industry to mean credit support or backup funds for a financial instrument or transaction. For example, bank revolving credit loans are often obtained to backstop commercial paper in the event that the commercial paper issuer defaults on its payments.
bank revolving credit loans
A revolving loan facility is a form of credit issued by a financial institution that provides the borrower with the ability to draw down or withdraw, repay, and withdraw again. A revolving loan is considered a flexible financing tool due to its repayment and re-borrowing accommodations. It is not considered a term loan because, during an allotted period of time, the facility allows the borrower to repay the loan or take it out again. In contrast, a term loan provides a borrower with funds followed by a fixed payment schedule.
net stable funding ratio
The net stable funding ratio is a liquidity standard requiring banks to hold enough stable funding to cover the duration of their long-term assets. For both funding and assets, long-term is mainly defined as more than one year, with lower requirements applying to anything between six months and a year to avoid a cliff-edge effect. Banks must maintain a ratio of 100% to satisfy the requirement.
value-at-risk
Value-at-risk is a statistical measure of the riskiness of financial entities or portfolios of assets. It is defined as the maximum dollar amount expected to be lost over a given time horizon, at a pre-defined confidence level.
