GS (Goldman Sachs) is the clearest beneficiary. Goldman is the most trading-intensive of the major U.S. banks, meaning its risk-weighted asset base under the old market-risk rules was disproportionately large. A reduction in standardized RWA calculations directly compresses the denominator in Goldman's capital ratio, freeing equity without requiring the firm to shrink. Goldman already raised its quarterly dividend 33% in mid-2025 and was one of six large banks collectively spending roughly $32 billion on buybacks in a single quarter in early 2026. Looser RWA rules mean the buyback authorization grows, not shrinks.
MS (Morgan Stanley) is in the same position. Morgan Stanley's Stress Capital Buffer was cut from 5.1% to 4.3% effective October 2025, and in June 2026 the firm announced a $20 billion share repurchase authorization alongside a $0.15 dividend increase. Basel III Endgame relief compounds this: lower standardized capital requirements mean Morgan Stanley can run its equity trading and wealth-management balance sheet harder without breaching ratio floors.
JPM (JPMorgan Chase) benefits as well, though less dramatically than its pure-play capital-markets peers. JPMorgan announced a $50 billion buyback authorization following the 2026 stress test cycle. As the largest U.S. GSIB, any reduction in the GSIB surcharge or RWA methodology translates directly into buyback capacity, even if the proportional RWA relief is smaller for a more diversified franchise.
BAC (Bank of America) stands to gain on its trading desk. BofA's markets division generates a meaningful share of total revenue, and RWA relief on market-risk positions would free capital that management can redirect toward capital returns — an area where BofA has historically lagged peers on a per-share basis.
Who is exposed
Non-bank financial firms that compete with bank trading desks on a level playing field lose their structural advantage when big banks can carry larger books. Specifically, market-making fintechs and broker-dealers without the deposit-funding backstop that banks enjoy face competitors who can now operate with a lighter capital load. More concretely, SCHW (Charles Schwab) competes with bank wealth-management and brokerage platforms. If MS and GS accelerate their direct-to-retail wealth pushes with capital freed from regulatory excess, Schwab's fee compression risk increases. Schwab also carries its own interest-rate sensitivity from its bond portfolio, meaning it has less room to compete on price as bank-affiliated wealth platforms expand.
The play / What to watch
The comment period on the revised proposals closed June 18, 2026. Watch for the final rule release — any further softening of the market-risk framework (specifically the Fundamental Review of the Trading Book, or FRTB, implementation) would be a second-order catalyst for GS and MS trading revenue. Track CET1 ratio disclosures in Q2 and Q3 earnings: if the ratio climbs above management targets, buyback acceleration is the mechanical result. The deregulation trade here is not a rumor — it is arithmetic.
