Banks balk at President Trump's call for 1-year, 10% cap on credit card interest

President Trump renewed a campaign pledge to cap credit-card interest rates at 10% within a year, a proposal researchers say could save consumers roughly $100 billion annually while materially reducing industry revenue and prompting cuts to rewards. Average credit-card APRs currently run about 19.65%–21.5%; the plan faces unified opposition from banks and trade groups and uncertain implementation routes (executive action vs. legislation) even as lawmakers from both parties have proposed similar bills. The proposal, paired with a deregulatory track record (including a recent Capital One/Discover merger and a weakened CFPB), creates political risk for card issuers and could materially reprice credit-card economics if enacted.

Analysis

Market structure: A 10% one-year cap would transfer roughly $100B/year from issuers to consumers per researchers — implying a ~50%+ cut in average card APR income (from ~20% to 10%) on revolvers. Direct losers are issuers and specialty consumer banks (Capital One COF, Synchrony SYF, Discover/merged entity) and credit-card-backed ABS investors; winners include rate-insulated deposit franchises (JPM, MS) and alternative lenders/BNPL (AFRM, PYPL). Large diversified banks can offset with interchange, annual fees and Treasury/markets revenue, compressing small-issuer margins and accelerating consolidation.

Risk assessment: Tail risks include rapid legislative passage or an executive action (high-impact, low-probability) forcing immediate repricing of issuer equity and ABS spreads, or conversely a legal block and industry lobbying reversing moves. Immediate (days) volatility around headlines, short-term (weeks–months) credit repricing and earnings-impact revisions, long-term (quarters) underwriting tightening and reduced unsecured supply. Hidden dependencies: issuers can offset ~20–50% of lost interest via rewards cuts, annual fees and stricter underwriting; migration to unregulated lenders would raise consumer default risk and ABS tail loss.

Trade implications: Implement short exposure to high-card-concentration issuers while hedging systemic spread risk: favor options put spreads on COF and SYF (6–9 month expiries) sized as 1–3% portfolio bets, and pair with 1–2% long positions in JPM or MS as safe-haven banking exposure. Buy protection against ABS/widening via a small position in HY CDX 5Y or long HYG/TCI put structures (size 0.5–1% portfolio) for a 3–12 month hedge. Opportunistic longs in AFRM/PYPL (1% each) if consumer demand shifts to BNPL, but cap positions if CFPB targets BNPL within 90 days.

Contrarian angles: Markets may overprice the legislative probability — if passage probability ≤30% the sell-off is a short-term binary trade; issuers’ ability to cut rewards and increase fees means eventual EPS hit could be smaller than headline APR math implies. Historical parallels (usury caps, CARD Act) show partial mitigation via product redesign and credit tightening rather than wholesale industry collapse. Unintended consequence: credit supply contraction could boost prime-card profitability and reduce charge-offs, offsetting some interest revenue loss over 6–12 months.

Key Decisions for Investors

• Establish a 2% portfolio short position in Capital One (COF) via a 6-month put spread (buy ATM put, sell 25% OTM put) sized to limit max loss; reduce or exit if Senate/House bill fails to gain 15+ co-sponsors or if White House clarifies no executive action within 60 days.
• Implement a relative-value pair: overweight JPMorgan (JPM) +2% vs short COF -2% for 3–9 months to capture dispersion; thesis: JPM diversified fee/markets offsets card-rate hit concentrated in COF.
• Buy defensive ABS/credit protection: allocate 0.75% portfolio to HY CDX 5Y protection or alternatively buy 3-month ATM puts on HYG sized to hedge consumer ABS widening; adjust if ABS OAS widens >50bps.
• Take a tactical 1% long in Affirm (AFRM) or PayPal (PYPL) expecting share gains from constrained card supply; cap exposure and exit if CFPB issues BNPL regulation or if the original bill attains >40% Senate support within 90 days.
• Trigger-based sizing: monitor for bill introduction or White House executive-order signal in next 30 days — if formal legislative text appears with >10 GOP co-sponsors, double short sizes within 5 trading days; if no material progress in 60 days, trim shorts by 50%.
