Will Goldman Sachs report a standardized CET1 ratio below 12.0% in Q2 2026 earnings?

The math suggests Q2 at Q1 pace gets CET1 to roughly 12.1-12.3%, which is close to but not below 12.0%. To breach 12.0% requires an additional adverse driver — either PCL acceleration, a large market risk RWA inflation, or an earnings miss that reduces capital accretion. Each of these individually has moderate probability (~30%) but the compound probability of breach is lower. Management is also likely to moderate buybacks modestly in response to the Q1 trajectory, which would prevent breach.

The 150bps single-quarter drop was unusual and reflects deliberate capital deployment at a pace that isn't indefinitely sustainable. Management is clearly aware of the buffer dynamics and will adjust if needed. The PCL build is early-cycle concerning but $315M isn't at a level that threatens capital. Market risk RWAs inflated but volatility may moderate in Q2. I estimate 20% — meaningfully possible but below base case.

I give slightly more weight to the compound scenario where PCL accelerates, market RWAs continue expanding, and the buyback pace stays high because management committed to it publicly. Under that scenario, CET1 could breach 12.0% without a single dramatic event. The 110bps buffer is genuinely thin — if anything unexpectedly adverse happens in Q2, the breach is possible. But base case management response would moderate before breach.

GS management has tools to prevent a breach — slow buybacks, defer balance sheet growth, hold earnings. They will use them if approaching 12.0%. The base case is modest CET1 decline to ~12.2-12.4% in Q2, not a breach. Historical pattern: banks rarely breach capital floors because management acts preemptively. 18% reflects the scenario probability, not the arithmetic probability.

The Q1 deployment pace was deliberately aggressive to position for a favorable regulatory window. Management likely has internal target for Q2 that preserves at least 100bps buffer. A breach below 12.0% would be a reputational hit management wants to avoid. I estimate 20% — not base case but not negligible given the compound scenario risks.

The thin buffer is genuine. If Q2 brings any combination of: further market risk RWA inflation (Middle East, credit stress), PCL at $400M+, buybacks at $4B+, and balance sheet growth continuing — the math gets tight. I weight these individually but allow for compound risk. Base case is ~12.1-12.3% exit, breach probability 20-25%.

A 150bps drop in one quarter is unusual and the 110bps buffer is notably thin. Another similar quarter would breach. Management is unlikely to repeat the exact pace but is also unlikely to abruptly slow. Expected outcome: moderate slowing with CET1 landing around 12.1-12.3%, not below 12.0%. Probability of breach: 20-25%.

Direct calculation: Q1 earnings $5.6B added ~55bps capital; Q1 buybacks $5B + dividends $1.4B removed ~70bps; balance sheet growth removed ~40bps; market RWAs removed ~30bps; net ~85bps decline (actual was 150bps, so additional 65bps from other factors). Q2 similar math suggests modest continued decline. Breach requires incremental adverse factor.

22% probability. The Q1 trajectory is clearly stressing the capital plan, but management discipline + earnings accretion + likely moderation prevent breach in base case. Tail risk from credit events or Basel III disappointment could push through, but both are relatively low probability.
