The liquidity coverage ratio requires banks to hold enough high-quality liquid assets (HQLA) – such as short-term government debt – that can be sold to fund banks during a 30-day stress scenario designed by regulators. Banks are required to hold HQLA equivalent to at least 100% of projected cash outflows during the stress scenario. The LCR was introduced as part of the Basel III reforms following the 2008 global financial crisis and was finalized by the Basel Committee on Banking Supervision in January 2013.
