Direct Answer
The Liquidity Coverage Ratio (LCR) is a prudential measure introduced under the Basel III reforms to promote the short-term resilience of the banking sector against liquidity shocks
The formula for LCR is the stock of High-Quality Liquid Assets (HQLA) divided by the total net cash outflows over the next 30 calendar days, which must be equal to or greater than 100 percent. HQLAs include cash, central bank reserves, and government securities
