Net stable funding ratio


During the financial crisis of 2007–2008, several banks, including the UK's Northern Rock and the U.S. investment banks Bear Stearns and Lehman Brothers, suffered a liquidity crisis, due to their over-reliance on short-term wholesale funding from the interbank lending market. As a result, the G20 launched an overhaul of banking regulation known as Basel III. In addition to changes in capital requirements, Basel III also contains two entirely new liquidity requirements: the net stable funding ratio and the liquidity coverage ratio . On October 31, 2014, the Basel Committee on Banking Supervision issued its final Net Stable Funding Ratio.
Both ratios are landmark requirements: it is planned that they will apply to all banks worldwide if they are engaged in international banking.

Net stable funding ratio (NSFR or NSF ratio)

The net stable funding ratio has been proposed within Basel III, the new set of capital and liquidity requirements for banks, which will over time replace Basel II. Basel III has been prepared within the Basel Committee on Banking Supervision of the Bank for International Settlements. Various components of Basel III are being implemented in different jurisdictions and Basel committee reports progress on the state of implementation through its Regulatory Consistency Assessment Programme which is published on a semi-annual basis.
Net Stable Funding ratio seeks to calculate the proportion of Available Stable Funding via the liabilities over Required Stable Funding for the assets.
These components of stable funding are not equally weighted: see page 21 and 22 of the Consultative Document dated December 2009 for the detailed weights.
Some of the weights for longer term or "structural term assets" are as follows
The consultative document will be amended.

NSFR

Implementation

As the Basel Committee on Banking Supervision does not have the power to issue legally binding regulation, the Basel III standards have to be implemented by national authorities. Consequently, there are differences among countries with respect to both content and timing.
The NSFR has become a minimum standard by 1 January 2018. However, implementation has been delayed in many countries. Less than half of the G20 members had implemented the rules by 2018. Among those that lag behind are the US, the EU, Switzerland and Japan. The compliant countries include Australia, Brazil, China, Indonesia and Russia.
Over time NSFR calibration will be reviewed as proposals are developed and industry standards implemented.

Off-balance sheet categories

As mentioned above, off-balance sheet categories are also weighted as they contribute to both the assets and liabilities. This is best explained by the potential for contingent calls on funding liquidity. Therefore, once the standard is in place, off-balance sheet commitments will need to be funded, with the stable funding.
This may help prevent the excessive use of the shadow banking system, including special purpose entity and structured investment vehicle, as these conduits often benefit from liquidity facilities granted by the bank which created them.
