The Liquidity Coverage Ratio (LCR) is indeed calculated as the ratio between high-quality liquid assets and net cash outflows over a 30-day period. This ratio is a key component of Basel III, a set of international banking regulations developed by the Basel Committee on Banking Supervision. The LCR is designed to ensure that banks have enough high-quality liquid assets on hand to survive a severe liquidity stress scenario lasting 30 days. High-quality liquid assets are those that can be easily and immediately converted into cash with little or no loss of value. Net cash outflows are the total expected cash outflows minus total expected cash inflows occurring in the next 30 days. The LCR must be greater than or equal to 100%, indicating that a bank has enough liquid assets to cover its total net cash outflows for 30 days.

Choice A is incorrect. The ratio between stable funding and high-quality liquid assets is not the Liquidity Coverage Ratio (LCR) according to Basel III. This ratio refers more to the Net Stable Funding Ratio (NSFR), another standard introduced by Basel III, which aims to promote resilience over a longer-term structural horizon by requiring banks to fund their activities with sufficiently stable sources of funding.

Choice B is incorrect. The LCR does not involve a ratio between high-quality liquid assets and total assets. Total assets include both liquid and illiquid assets, whereas the LCR specifically focuses on high-quality liquid assets that can be readily converted into cash in times of stress.

Choice D is incorrect. The ratio between stable funding and net cash outflows in a 30-day period does not define the LCR as per Basel III regulations. This choice seems to mix elements from both the LCR and NSFR standards but does not accurately represent either.

Things to Remember

• Basel III: Basel III is a global regulatory framework on bank capital adequacy, stress testing, and market liquidity risk. It aims to strengthen the regulation, supervision, and risk management within the banking sector.
