Stress Capital Buffer: Calculation, Calendar, and Breach Rules

The stress capital buffer is a bank-specific capital cushion the Federal Reserve sets each year for every large bank holding company, sized to what that firm’s own balance sheet would lose in a simulated severe recession plus what it plans to pay out in common stock dividends. It replaced the flat 2.5% capital conservation buffer in October 2020, and while 2.5% is still the floor no bank can go below, the actual requirement is now tailored to the firm.¹ In the August 2025 cycle, individual buffers ranged from the 2.5% floor at firms like JPMorgan Chase, Bank of America, and Wells Fargo to 11.5% at DB USA Corporation.²

Which Banks Have to Hold One

The rule reaches any top-tier U.S. bank holding company with average total consolidated assets of $100 billion or more over four consecutive quarters, plus U.S. intermediate holding companies of foreign banking organizations that clear the same threshold, and any nonbank financial company the Board designates by order. Once a firm crosses that line it stays covered until its assets sit below $100 billion for four straight quarters.¹

The Federal Reserve sorts these firms into Categories I through IV by size, complexity, and cross-border activity. Category I is the global systemically important banks. Categories II and III are large institutions with meaningful trading or cross-jurisdictional exposure. Category IV sits at the smaller end and gets one important break: those firms undergo supervisory stress testing every other year, in even-numbered calendar years, rather than annually. In the off years, their buffer is adjusted instead of recalculated from a fresh test.³ Community and regional banks under the $100 billion threshold are not subject to the buffer at all; they remain under the flat 2.5% capital conservation buffer.

How the Number Is Calculated

The buffer has two ingredients.

The first is the stress loss. Each year the Board publishes a severely adverse economic scenario, runs the bank’s balance sheet through it, and finds the quarter where common equity tier 1 (CET1) capital hits its lowest point. The difference between the starting CET1 ratio and that trough is the stress loss component.

The second is planned common stock dividends. The capital plan sets out the dollar amount of dividends the bank intends to pay across the fourth through seventh quarters of the nine-quarter planning horizon. That total is divided by the risk-weighted assets in the same quarter where CET1 bottomed out, producing a ratio.⁴

Add the two together, and that is the preliminary buffer. If the sum comes in under 2.5%, the floor applies and the buffer is set at 2.5%.⁴ A bank that holds up well in the stress test and plans modest dividends sits at the minimum. A bank with large projected losses or a heavy dividend plan ends up well above it.

Notice what is not in the formula: share repurchases. Only common stock dividends feed the dividend component. That distinction is deliberate, since buybacks can be paused quickly in a real downturn while a dividend cut sends a public signal management usually tries to avoid.⁵

The Annual Calendar

The buffer runs on a fixed yearly cycle.

By April 5, banks submit their capital plans to the Board and their Reserve Bank, including projected capital actions, planned dividends, and internal stress testing results.¹
By June 30, the Board provides preliminary notice of the bank’s buffer along with the supervisory stress test results.
By August 31, the Board issues the final buffer requirement and confirms the bank’s final planned distributions.
On October 1, the new buffer takes effect and stays in force until the next cycle supersedes it.⁶

p>The window between the June preliminary notice and the August final notice is where a firm can request reconsideration or adjust its planned dividends before the number locks in.

How It Fits Into Total Capital Requirements

The buffer does not stand alone. It sits on top of the 4.5% minimum CET1 ratio, and for the largest firms other buffers stack above it.

Take a straightforward case: a bank with a 3.5% stress capital buffer and no other surcharges needs a CET1 ratio of at least 8.0% to avoid any distribution restrictions.⁴ A global systemically important bank also carries a GSIB surcharge, calculated under two methods with the higher result applying, and that surcharge stacks directly on top of the buffer.⁷ A GSIB with a 2.5% buffer and a 3.5% surcharge needs CET1 of at least 10.5%.

A countercyclical capital buffer can also apply if the Board activates it. It has been set at 0% in the United States for the entire history of the stress capital buffer framework, so in practice it has not added to total requirements. If turned on, it would stack alongside the buffer and any GSIB surcharge.⁸

What Happens if a Bank Falls Into the Buffer

When CET1 drops into the buffer zone, distribution restrictions kick in automatically. No hearing, no negotiation. The limits scale with how deep the shortfall runs, measured in quartiles of the buffer.⁹

Above the full buffer, there are no payout limits.
In the top quartile (75%–100% of the buffer remaining), the bank can distribute no more than 60% of eligible retained income.
In the second quartile (50%–75%), the cap drops to 40%.
In the third quartile (25%–50%), it drops to 20%.
In the bottom quartile (below 25%), no distributions are permitted.

Eligible retained income is defined as the greater of the bank’s net income over the prior four quarters (net of distributions) or the average of those four quarters’ net income. Using the larger of the two keeps a single bad quarter from artificially zeroing out the allowance.¹⁰

The restrictions cover more than shareholder payouts. Dividends and share repurchases face the same limits, and discretionary bonus payments to senior executives are capped within the buffer zone as well. Management cannot redirect suppressed dividends into bonuses while the firm rebuilds capital.¹¹

Challenging the Number and Mid-Cycle Recalculations

A firm that thinks its preliminary buffer is wrong has 15 calendar days after receiving notice to submit a written request for reconsideration to the Board. The request must explain in detail why the buffer should be modified, and if the bank wants to introduce data it did not include in its original capital plan, it also has to explain why that information should be considered now.¹

An informal hearing can be requested as part of the reconsideration. The Board decides in its sole discretion whether to grant one, and if it does, the hearing must take place within 30 days of the request. The Board then has 30 days after the hearing, or after receiving the written request if no hearing is held, to affirm or modify the buffer. While the reconsideration is pending, the bank can keep making distributions consistent with the preliminary buffer’s automatic limits.

Outside the annual cycle, the Board can recalculate a buffer when a firm’s risk profile changes materially. Triggers include mergers and acquisitions, significant shifts in financial markets or the macroeconomic outlook, and situations where the Board concludes the firm’s internal stress scenarios no longer fit its business model.¹² When a mid-cycle recalculation happens, the Board does not average the new result with the prior year’s stress test, since blending old and new figures would distort what the firm now looks like. The bank can adjust its planned dividends and request reconsideration on the same terms as in the regular cycle.

What Changed From the Old Framework

Before October 2020, every large bank sat under a static 2.5% capital conservation buffer regardless of its own risk. The Board also ran the Comprehensive Capital Analysis and Review, which could produce a quantitative objection to a bank’s capital plan and effectively block planned dividends and buybacks for the whole year. The stress capital buffer folded both mechanisms into one: stress test results now flow directly into a firm-specific buffer that triggers automatic distribution limits when breached.⁵

Banks no longer need prior Board approval to raise dividends or launch buybacks beyond what their capital plan contemplated, so long as they stay above their buffer. The annual quantitative objection is gone. And the dividend assumption inside the stress test is narrower than it used to be, covering four quarters of planned common stock dividends rather than every planned distribution across the full nine-quarter horizon.
