Trump wants to cap credit card interest rates at 10%. But such limits could harm consumers, experts warn

U.S. credit card APRs have risen from under 15% four years ago to over 21% by 2024, with many consumers facing rates above 30%. President Trump has proposed a one-year 10% cap on credit card interest effective Jan. 20, following a separate Sanders–Hawley proposal for a five-year 10% cap, while the Durbin–Marshall Credit Card Competition Act would force large issuers to support alternative networks and targets the dominant Visa/Mastercard swipe fees (about $93 billion in 2022). Analysts and industry groups warn that simultaneous caps on APRs and swipe-fee reductions would materially curtail issuer revenue, threaten rewards programs, reduce credit access for higher-risk borrowers and could push some consumers toward costlier alternatives.

Analysis

Market structure: A 10% APR cap and swipe‑fee reform would transfer tens of billions of revenue away from card issuers and networks and toward merchants/consumers, compressing issuer NIMs and forcing a retrenchment of unsecured credit. Winners: merchants, fintechs that can offer alternative routing or fixed‑fee models, and lenders with secured/dually diversified funding. Losers: pureplay card issuers and rewards‑funded ecosystems; V/MA face direct pressure on interchange volumes and pricing power.

Risk assessment: Tail risk is legislative passage (low probability today but high impact) that could cut card interest revenue by 30–60% for unsecured portfolios and reduce Visa/Mastercard interchange take rates by 10–25% over 12–24 months. Near term (days–weeks) expect volatility spikes around committee votes and the Jan 20 election; medium term (3–12 months) expect credit tightening and higher delinquencies as issuers tighten underwriting. Hidden dependencies include airline/hotel loyalty partnerships and securitization cash flows that rely on interest margins; disruption could impair ABS spreads and bank loss provisioning.

Trade implications: Tactical short exposure to V (V) and MA (MA) via 3–6 month put spreads sized 0.5–1.5% portfolio each is prudent; pair trade long diversified balance‑sheet banks (JPM, BAC) vs short card‑centric issuers (COF, SYF) for 3–12 months. Buy protection on consumer unsecured ABS or increase IG allocation by 2–4% as a credit hedge; expect options IV to rerate on legislative headlines so favor defined‑risk structures. Entry window: build positions on committee votes/hearing days; unwind partial exposure if no bill traction in 90 days.

Contrarian angles: Markets may be overpricing instantaneous doom for V/MA—networks can pivot to data/merchant products, surcharges, or fixed routing fees, as seen post‑Durbin (2011) where revenue recovery occurred over 24–36 months. The consensus underestimates issuer behavioral responses: higher annual fees, tighter underwriting, and shift to secured products could preserve aggregate profitability; this creates mispricings in front‑month options and midcap credit that can be exploited.

Key Decisions for Investors

• Establish a combined 1.6% portfolio short via 3–6 month put spreads on V (0.8%) and MA (0.8%); use 10% OTM puts bought and 15% OTM puts sold to limit cost—target asymmetric payoff if legislation advances within 90 days.
• Initiate a 2% pair trade: long JPM (1.2%) / short COF (0.8%) for 3–12 months anticipating diversified deposit & trading income to outperform card‑dependent origination; set stop‑loss at 10% adverse move.
• Allocate 2–3% to IG corporate bonds (5–10y) and/or buy protection on consumer unsecured ABS (or ABS CDS equivalent) to hedge rising delinquencies; target IG yield pickup of 50–100bp over Treasuries as a buffer.
• If congressional committee votes or public hearings occur within 30 days, increase hedges: add another 0.5–1% short on V/MA and roll into longer dated (9–12 month) protection if bill gets bipartisan momentum; if no bill progress in 90 days, reduce option hedges by 50%.
