This document, published in December 2010 by the Basel Committee on Banking Supervision, presents the international framework relating to the measurement, standards, and monitoring of liquidity risk in the banking sector, within the Basel III regulatory initiative. It covers liquidity standards applicable to internationally active banks, focusing on two key ratios: the Liquidity Coverage Ratio (LCR) and the Net Stable Funding Ratio (NSFR). The scope includes international banks, with globally harmonized parameters, while allowing some leeway for national authorities to adapt certain parameters according to local specificities. The document spans approximately 53 pages, of which the first 31 pages are provided for this summary. It is superseded by later publications in 2013 and 2014.
The document addresses the strengthening of the international regulatory framework on banking liquidity risk management, in response to weaknesses revealed by the 2007-2008 financial crisis. It aims to improve banks' resilience to financial and economic shocks, thereby reducing contagion risks to the real economy (p. 7). Two main standards are introduced: the Liquidity Coverage Ratio (LCR) to ensure short-term resilience over 30 days by maintaining a sufficient stock of high-quality liquid assets to cover net cash outflows under a severe stress scenario (p. 9-10), and the Net Stable Funding Ratio (NSFR) to promote a stable funding structure over a one-year horizon (p. 7). These standards are internationally harmonized but incorporate elements of national discretion, which must be transparent (p. 8, 13). The LCR requires that the value of high-quality liquid assets be at least equal to 100% of expected net cash outflows over 30 days, calculated according to a scenario combining idiosyncratic and systemic shocks, including notably partial loss of deposits and funding, collateral requirements linked to rating downgrades, and drawings on committed credit lines (p. 15-18, 50-54). Eligible liquid assets are classified into two levels (Level 1 unlimited, Level 2 limited to 40% of the stock after haircut), with strict criteria on quality, liquidity, and central bank eligibility, and haircuts applied to Level 2 (p. 14-17). The document also details the calculation methods for cash outflows and inflows, with differentiated run-off rates according to the nature of deposits, counterparty quality, and stability of operational relationships (p. 18-29). Complementary monitoring tools are provided to track liquidity by currency, funding concentration, and other indicators (p. 5). A transitional period is established to allow banks to comply progressively, with LCR effective January 1, 2015, and NSFR effective January 1, 2018 (p. 8-9). In conclusion, these standards aim to strengthen liquidity risk management and supervision by imposing global minimum requirements while allowing local adaptation, to prevent future crises and protect financial stability.
The financial crisis beginning in 2007 highlighted major shortcomings in banks' liquidity risk management, even for those with adequate capital levels (p. 7). This crisis revealed how quickly liquidity can evaporate and how prolonged illiquidity can be, requiring central bank interventions to support money markets and certain institutions. In response, the Basel Committee published in 2008 the "Principles for Sound Liquidity Risk Management" to improve the management and supervision of this risk. However, these principles require rigorous implementation. To strengthen this framework, the present document introduces two minimum international standards: the LCR to ensure short-term resilience under severe 30-day stress, and the NSFR to promote a stable funding structure over a one-year horizon (p. 7-8). The objective is to reduce financial contagion risk to the real economy, improve banking sector resilience, and harmonize regulatory practices globally while considering national specificities (p. 8, 13). The document also specifies the scope of application, transitional arrangements, and complementary monitoring tools for effective supervision (p. 8-9).
1. Objectives of liquidity standards:
- The LCR aims to ensure that banks hold a sufficient stock of high-quality liquid assets to cover net cash outflows over 30 days under severe stress, combining idiosyncratic and systemic shocks (p. 7, 9, 17-18).
- The NSFR encourages a stable funding structure over a one-year horizon, reducing reliance on volatile short-term funding (p. 7, 25).
2. Definition and composition of the stock of high-quality liquid assets (HQLA):
- Assets must be easily and immediately convertible into cash without significant loss of value, and ideally eligible for central bank facilities (p. 11, 24).
- Fundamental characteristics include low credit and market risk, ease of valuation, low correlation with risky assets, and listing on developed markets (p. 11-12).
- Assets are classified into two levels: Level 1 (cash, central bank reserves, high-quality sovereign securities) with no limit and no haircut, and Level 2 (lower-rated sovereign securities, high-quality corporate bonds and covered bonds) limited to 40% of the stock after a minimum 15% haircut (p. 14-17).
- Specific treatments are provided for jurisdictions with insufficient liquid assets, including contractual central liquidity facilities, use of controlled foreign currency assets, and possible extension of Level 2 with increased haircuts (p. 16-18).
3. Calculation of net cash outflows:
- Outflows are calculated by multiplying the balances of liabilities and off-balance sheet commitments by specific run-off or drawdown rates depending on the nature of funds and counterparty category (p. 50-51).
- Retail deposits are divided into "stable" (minimum 5% run-off) and "less stable" (minimum 10%), with criteria related to deposit insurance coverage, client relationship nature, and early withdrawal possibility (p. 18-20).
- Wholesale funding is segmented according to counterparty nature and operational relationship stability, with run-off rates ranging from 5% to 100% (p. 20-23).
- Secured funding is treated according to the quality of underlying assets, with funding loss rates ranging from 0% (Level 1) to 100% (others) (p. 23-24).
- Additional needs related to rating downgrade clauses, collateral valuation changes, and refinancing of structured securities are integrated (p. 24-26).
- Drawings on committed credit lines are accounted for with differentiated drawdown rates depending on client nature (p. 26-27).
4. Limitation of cash inflows:
- Cash inflows considered are only contractual flows from performing exposures, capped at 75% of outflows to avoid excessive dependence (p. 29).
- Reverse repos and securities borrowing are treated according to collateral quality and nature of short positions (p. 29-30).
5. Operational and management requirements:
- Liquid assets must be unencumbered, continuously available, and managed by the liquidity management function (p. 26-29).
- Banks must periodically test the liquidity of these assets on the market (p. 12).
- The ratio must be continuously complied with and monitored by currency, with specific monitoring tools to detect imbalances (p. 32-37).
6. National discretion and transparency:
- Certain parameters, notably run-off rates and specific treatments, may be adapted by national authorities, subject to transparency and publication (p. 8, 13, 51, 100).
7. Transitional period and implementation:
- An observation period begins in 2011, with LCR implementation on January 1, 2015, and NSFR on January 1, 2018, allowing banks to adjust portfolios and practices (p. 8-9, 40).
- Rigorous monitoring is planned to assess impacts on markets and the economy, with possible revisions (p. 8-9).
Established facts:
- The financial crisis demonstrated that adequate capital levels alone do not guarantee banking resilience without rigorous liquidity management (p. 7).
- The LCR requires banks to hold a stock of high-quality liquid assets covering at least 100% of net cash outflows over 30 days in a stress scenario combining idiosyncratic and systemic shocks (p. 9-10, 17-18).
- Liquid assets are classified into Level 1 and Level 2, with strict criteria and quantitative limits, to ensure availability even under stress (p. 14-17).
- Cash outflows are calculated according to differentiated run-off rates by deposit type, counterparty, and funding nature, integrating drawings on committed credit lines and needs related to rating downgrade clauses (p. 18-29).
- Cash inflows are capped at 75% of outflows to avoid excessive dependence (p. 29).
Assumptions:
- The stress scenario combines several elements observed during the 2007-2008 crisis, assuming notably a rating downgrade of up to three notches, partial loss of deposits and funding, and drawings on credit lines (p. 17-18).
- Run-off and drawdown rates are internationally harmonized, but some are left to national discretion, with transparency obligations (p. 51).
- Intraday liquidity is not covered by the LCR (p. 31).
Interpretations:
- The implementation of the LCR and NSFR should strengthen banks' capacity to absorb liquidity shocks in the short and medium term, thus reducing systemic risks (p. 7-9).
- The classification of liquid assets and applied haircuts aim to avoid forced sales and confidence degradation in markets (p. 11-13).
- Limiting cash inflows to 75% of outflows ensures banks maintain a real liquidity buffer (p. 29).
Uncertainties:
- The effectiveness of the standards will depend on rigorous implementation and banks' capacity to actively manage liquidity (p. 7).
- Some parameters left to national discretion could lead to divergences in application and international comparability (p. 8, 13).
- Treatment of foreign currencies and alternative options for jurisdictions with insufficient liquid assets remain to be finalized after the observation period (p. 16-18).
- Treatment of intraday liquidity risk is not yet defined (p. 31).
The Basel Committee concludes that implementing the LCR and NSFR standards is essential to strengthen the banking sector's resilience to liquidity risks, by imposing harmonized minimum requirements internationally while allowing adaptation to national specificities (p. 7-9, 13). It recommends that banks continuously comply with these standards, complemented by more severe internal stress tests and rigorous management practices (p. 19). Supervisory authorities must ensure rigorous, transparent, and consistent implementation, with close monitoring of impacts on markets and the economy, and be ready to adjust standards based on observations during the transitional period (p. 8-9, 100). The Committee emphasizes the importance of prudent management of liquid assets, diversification of funding sources, and control of risks related to foreign currencies (p. 12, 32-37). Finally, it foresees an observation period starting in 2011, with LCR effective January 1, 2015, and NSFR effective January 1, 2018, to allow banks to adapt progressively (p. 8-9, 40).
