Capital Conservation Buffer

Q: Is the capital conservation buffer separate from the stress capital buffer?

For large banks subject to the Comprehensive Capital Analysis and Review (CCAR) stress tests, the CCB is replaced by the Stress Capital Buffer (SCB), which floors at 2.5% but can exceed it based on stress-test results.

Q: What happens if a bank falls into the buffer?

Section §217.11 caps the bank's eligible payout ratio: dropping deeper into the buffer caps dividends, buybacks, and bonuses at a progressively smaller share of net income for the prior four quarters.

Q: Does CBLR have a capital conservation buffer?

No. CBLR is a single 8% threshold (9% before July 1, 2026) with a grace period of up to four quarters down to 7%. The buffer architecture only applies to banks using the standard risk-based framework.

Also known as CCB

The Capital Conservation Buffer (CCB) is a 2.5% layer of CET1 capital that sits on top of the Basel III minimums. Banks operating inside the buffer face automatic restrictions on dividends, share buybacks, and discretionary bonuses.

How is CCB calculated?

CCB requirement: CET1 ratio ≥ 4.5% + 2.5% = 7.0%

The CCB is not a separate ratio. It is an additional cushion of CET1 that each bank must hold beyond the 4.5% CET1 minimum. The same 2.5% buffer applies on top of the Tier 1 (6.0% + 2.5% = 8.5%) and Total Capital (8.0% + 2.5% = 10.5%) minimums.

Why does CCB matter?

Operating inside the buffer doesn't make a bank undercapitalized. But it does limit the bank's ability to return capital. The deeper a bank dips into the buffer, the more severe the payout restriction: a bank with CET1 just above 4.5% can distribute almost nothing. The CCB is how regulators discourage capital depletion during stress without forcing immediate failure resolution.

How do you interpret CCB?

Healthy banks operate at least 100-200 bps above the buffer-included minimum (so above 9% CET1 for normal banks; higher for G-SIBs). Between 7% and 9% the bank meets the buffer and faces no regulatory payout limit, though the cushion is thin; below 7% the payout limits of 12 CFR 324.11 (217.11 at the Federal Reserve) apply.

What is a good CCB?

Range	Label	Interpretation
≥ 9% CET1	Above buffer	Unrestricted capital distributions.
7–9% CET1	Buffer met	No regulatory payout limit; thin management cushion.
5.75–7%	Restricted	Maximum payout ratio limited.
< 5.75%	Severely restricted	Approaching the 4.5% hard minimum.

Worked example

A community bank with 8.2% CET1 is 3.7 points above the 4.5% minimum: the full 2.5-point buffer plus 1.2 points of cushion. No regulatory payout limit applies, but with only 120 bps above the 7.0% buffer line it has little room to absorb losses before limits on dividends, buybacks and discretionary bonuses would begin.
