Capital Buffer
A capital buffer is an additional layer of capital that banks must hold above minimum regulatory requirements.
Meaning in Practice
In practice, capital buffers are designed to absorb losses during periods of financial stress. They sit above the minimum capital ratio and may include conservation or countercyclical components. Banks breaching buffers face restrictions on dividend distributions.
Why It Matters
Capital buffers enhance the resilience of banks during downturns. They reduce the likelihood of insolvency and protect depositors. Buffers also help smooth the credit cycle.
Market Impact
Higher buffer requirements can constrain capital distributions and lending. Markets often reassess bank valuations when buffer levels change. Strong buffers generally lower perceived default risk.
Example
During an economic expansion, regulators may require banks to build additional capital buffers to prepare for potential future losses.
