Liquidity risk measures

Published: 25th March 2017 by William Webster

Banks are required to measure the inflows and outflows of cash over a designated period (30 days). This is undertaken for business as usual and stressed conditions. To make stress testing relevant the scenarios are designed by the individual bank.

This analysis leads to banks holding High Quality Liquid Assets (HQLA). These are used to cover liquidity shortfalls in times of stress.

The Liquidity Coverage Ratio (LCR) is the key measure. It compares the HQLA held with the net cash outflows under stressed condition and thereby indicates whether the bank is sufficiently liquid.

By calculating the LCR banks undertake a detailed examination of their balance sheets. This involves evaluating all the factors that affect cash inflows and outflows. The process needs regular (at least annual) updating.

Regulators review and evaluate how a bank has undertaken the assessment. Should the assessment be insufficiently detailed a regulatory “add-on” may result.

The following explanation is high level and the rules and methods vary between different banks and different jurisdictions.

The FSA presumes that every firm must be self sufficient for liquidity purposes unless a waiver is granted. The systems and controls requirement applies to all firms from Q4 2009 and will have no phased or transitional introduction. This is a summary of the CP.

In a world where regulators are focusing on liquidity and capital it's easy to overlook market risk. In many firms this means interest rate exposure. In the UK with Bank Rate at an all time low it's tempting to think that hedging fixed rate assets is just a waste of money. After all why pay 3.25% on a 5 year swap when 3 month Libor is only 51 basis points? Surely matching the interest basis on assets and liabilities ends up costing you 274 bps doesn't it?

A contractual cash flow report for a bank will show you that liabilities have shorter maturities than assets. That's because running liquidity risk generally makes money. But it has risks. Lack of confidence can lead to a real shortage of cash. That's why banks hold liquidity buffers. But measuring liquidity risk goes beyond what is contracted. It needs to assess the behaviour of markets and individuals. It's why stress testing is in vogue. Stress testing can't predict the future but it can give you an estimate for your liquidity buffer. It's likely to be a lot bigger than previously and it's going to cost your firm more, that's unless you can pass the cost on through transfer pricing.

7th November 2009

Policy Statement 09/16 Strengthening liquidity standards refers to earlier consultation papers CP08/22, CP09/13 and CP09/14 and the comments received. In general whilst the FSA acknowledges many of the issues raised little has altered in the final policy. Firms will be expected to be self sufficient for liquidity purposes. Senior management is responsible for reviewing the level of liquidity, compliance and reporting to the Board. The FSA highlights that many firms have been unable to identify and report contractual cash flows on a regular basis. This will be unacceptable. Non compliance will be treated with regulatory sanction. How a firm is subject to Individual Liquidity Adequacy Standards (ILAS) depends on the size of the firm and the risks it presents. The ILAS framework comprises an Individual Liquidity Adequacy Assessment (ILAA), a Supervisory Liquidity Review Process (SLRP) and Individual Liquidity Guidance (ILG). Firms are obliged in the ILAA to undertake robust stress testing. The purpose of this is to show that the firm fully understands its liquidity risk. ILAS firms will need to report the stress test results in their ILAA. Liquidity management systems, controls and stress testing are all board responsibilities. The ILG is the amount of liquid resources the FSA expects a firm to hold. This will contain "guidance" on the amount of the liquid asset buffer and the firm's funding profile. As an incentive for firms to improve their systems and controls, the FSA will increase the amount of liquidity the firm must hold. Deposits at the central bank and tradable securities issued by the central bank will count towards the buffer. Holding currency denominated bonds should take into account potential problems in the FX market. For this reason a domestic bank with mainly sterling liabilities must hold its buffer in gilts. The FSA now require firms to price the cost of liquidity into products. This should mean that the cost of holding the liquidity buffer is passed on to those customers that create a stressed outflow requirement. The new regime will be phased in. The scope and application of the new rules will depend on the importance of the firm and its ability to create systemic risk.

31st January 2009

This CP sets out the FSA's plans to reform the liquidity regime. It requires firms to undertake a much more rigorous analysis of their liquidity position. This includes the effect of stressed conditions on their business. The firm will submit what it considers to be an appropriate liquidity buffer to the regulator. The FSA will then decide whether it is sufficient. In determining the buffer the FSA will also assess the firm's systems and management. If these are considered weak the buffer will be increased accordingly. The liquidity buffer can only be held in liquid assets. The FSA's view is that this primarily means Gilts, sovereign debt or central bank deposits. The FSA makes it clear, "The responsibility of adopting a sound approach to liquidity risk management is on firms and their senior management".
