How U.S. Banks Should Rethink Credit Card Strategy in a Potential 10% APR Cap Environment
However, the policy discussion around a potential 10% APR cap on credit cards introduces structural uncertainty that banks can no longer ignore. Legislative proposals such as the “10 Percent Credit Card Interest Rate Cap Act” (S.381, 119th Congress) would limit APR to 10% inclusive of finance charges and restrict fee-based circumvention mechanisms (Congress.gov, 2025).
Even if such a cap is not enacted immediately, regulatory and political pressure is clearly increasing.
According to the CFPB Credit Card Market Report (2025), average APRs on general-purpose credit cards exceeded 25% in 2024, and interest charges totaled more than $160 billion that year. These figures highlight how central pricing flexibility is to current portfolio economics (CFPB, 2025).
If yields were materially compressed toward 10%, profitability in revolver-heavy portfolios would likely decline significantly. The issue is not cyclical volatility — it is potential structural redesign.
What a 10% APR Cap Would Change in Practice
Credit card interest represents one of the largest sources of consumer lending income in the United States. The CFPB reports that interest charges on credit cards exceeded $160 billion in 2024 (CFPB, 2025).
If allowable APR were reduced from the current mid-20% range to 10%, the interest cushion that absorbs:
- credit losses,
- operating expenses,
- and capital costs
would narrow materially.
Under such a scenario:
- Subprime-heavy revolving portfolios would become more economically fragile,
- The loss buffer per account would shrink,
- Fee structures would face closer regulatory examination, particularly given anti-avoidance language in proposed legislation (S.381, 2025),
- Underwriting standards would likely tighten.
CFPB data also shows large differences in approval rates across credit tiers, with substantially higher approval rates for superprime applicants compared to subprime segments (CFPB, 2025). If pricing flexibility is constrained, lower-credit segments become harder to justify on a risk-adjusted basis.
The strategic question shifts from:
“How do we defend current margins?”
to:
“How do we redesign portfolio architecture?”
Why the Traditional Revolving Model Is Exposed
The revolving credit card model depends on three core variables:
- Customer behavior,
- Macroeconomic stability,
- Pricing flexibility.
When pricing flexibility declines, behavioral volatility remains — but compensation narrows.
Historically, higher APRs allowed issuers to offset higher expected loss rates in certain segments. If APR is capped, that balancing mechanism weakens. Subprime or revolver-dominated portfolios, which often exhibit materially higher net charge-off rates than prime transactor segments, become structurally more sensitive to economic stress.
This does not eliminate the viability of credit cards. It changes the economic drivers.
Duration, repayment design, and revenue diversification begin to matter more than headline APR.
Installment Architecture as a Structural Adjustment
One practical response to yield compression is the expansion of installment functionality within credit card portfolios.
Instead of relying solely on open-ended revolving balances, issuers can allow customers to convert specific purchases into fixed-term repayment schedules.
This approach changes the economic profile:
- Cash flows become more predictable.
- Behavioral volatility decreases.
- CECL forecasting becomes more precise.
- Duration management improves.
Installment conversion does not eliminate credit risk. However, it shifts risk from indefinite behavioral carry to structured amortization.
In a lower-yield environment, structured repayment becomes a strategic stabilizer.
The Role of Secured and Hybrid Card Structures
Another adjustment likely to gain relevance is the expansion of secured or partially secured credit card programs.
Deposit-backed or collateral-enhanced products:
- Reduce loss given default,
- Improve capital stability,
- Provide controlled exposure to near-prime segments.
Rather than exiting certain risk bands entirely, banks can redesign exposure using collateral components that protect downside risk.
This is not retrenchment. It is risk recalibration.
From Interest-Centric to Ecosystem-Centric Revenue
If interest margins narrow, interchange and partnership economics gain relative importance.
High-FICO transactors — customers who pay balances in full — traditionally generate less interest income but meaningful interchange revenue. In a compressed APR environment, this segment becomes strategically more attractive.
Large issuers’ public filings demonstrate how diversified card portfolios include significant non-interest revenue streams alongside interest income (see, for example, Capital One 2024 Form 10-K, SEC, 2025). While interest income remains important, portfolio mix and usage-driven revenue materially influence overall profitability.
Similarly, embedded POS financing, merchant-funded promotions, and retail installment programs shift part of the economic base away from rate-sensitive revolving balances.
The structural evolution can be summarized as:
Interest-driven portfolio → Diversified revenue portfolio.
Banks that proactively diversify revenue streams reduce reliance on regulatory-sensitive pricing.
Precision Risk Management as a Core Profit Lever
When yield flexibility narrows, marginal improvements in loss performance have outsized impact.
For example, in a $10 billion credit card portfolio, a 5 basis point (0.05%) reduction in net losses represents $5 million annually in preserved pre-tax income.
AI-driven underwriting and portfolio management tools can support:
- Early delinquency detection,
- Dynamic credit line adjustments,
- More granular segmentation,
- Improved loss forecasting.
In a capped-rate environment, predictive accuracy becomes a primary competitive differentiator.
Pricing power declines; risk intelligence rises.
Technology Architecture as a Strategic Constraint
Redesigning card strategy is not solely a credit decision. It is also a technology decision.
Many legacy card platforms were built around traditional revolving logic and may not easily support:
- Hybrid installment overlays,
- Rapid fee-structure adjustments,
- Real-time AI integration,
- Accelerated product experimentation.
In stable regulatory conditions, slower product cycles may be tolerable. In transitional conditions, they become limiting.
- Architecture affects speed,
- Speed affects adaptability,
- Adaptability affects competitiveness.
Scenario Planning: Preparing for Multiple Outcomes
Boards should model both regulatory outcomes:
If no cap is enacted:
- Gradual diversification toward installment and ecosystem revenue strengthens resilience.
If a cap is enacted:
- Subprime revolving exposure likely contracts,
- Installment deployment accelerates,
- Risk modeling precision becomes critical,
- Revenue diversification becomes urgent.
A probabilistic planning approach — rather than binary thinking — enables balanced capital allocation.
The banks that prepare early will adjust at lower operational cost.
Conclusion: The Card Business Is Entering a Structural Transition
The U.S. credit card market is not disappearing. It is evolving.
Regulatory scrutiny, potential pricing constraints, and capital sensitivity are increasing the importance of:
- Portfolio structure,
- Repayment design,
- Revenue diversification,
- Risk intelligence,
- Technology flexibility.
Future profitability will depend less on maximizing APR and more on optimizing architecture.
