Trump’s Proposed 10% APR Cap Could Crimp Capital One’s Card Income

COFCOF

President Trump’s proposal to cap credit card APRs at 10% would force Capital One to reduce typical card rates well below its current average, squeezing net interest margins. The cap could cut card interest income and customer fee revenue, potentially prompting tighter lending standards or reduced rewards offerings.

1. Revenue and Earnings Estimates

Capital One Financial is projected to report fourth-quarter revenues of approximately $8.5 billion, representing year-over-year growth of roughly 7.8%. Wall Street’s consensus earnings per share estimate stands at $4.10, down 3% from last year’s fourth-quarter result. Analysts attribute the EPS dip to normalization of net interest margins following elevated funding costs in the first half of 2025. Despite the EPS moderation, revenue estimates remain upwardly revised by 2.5% over the past month as credit card spending continues to strengthen.

2. Loan and Card Growth Metrics

Card loan balances are expected to increase by 9.5% year-over-year, driven by a 12% uptick in new account originations and a 6% rise in average consumer spending per account. Total managed loans, including auto and commercial segments, are forecast to expand by 5.2%, reflecting disciplined underwriting and sustained demand in unsecured credit portfolios. Net charge-off rates are projected at 2.35%, modestly above the 2.20% recorded in Q4 2024 but in line with peer bank averages under current credit conditions.

3. Discover Acquisition and Synergies

Following the announced Discover Financial Services deal, Capital One expects to realize $300 million in annual pre-tax cost synergies by 2027. Integration costs of about $200 million will be recognized this quarter, temporarily pressuring operating efficiency. Management forecasts cross-sell revenue uplift of $150 million in Q4, stemming from joint marketing of co-branded cards and the rollout of Discover’s loyalty platform to Capital One’s 65 million cardholders. Investors will closely watch guidance on net interest margin stabilization and the pace of synergy capture once the transaction closes.
