The Credit Card Accountability Responsibility and Disclosure (CARD) Act of 2009 is a landmark piece of federal legislation designed to protect credit card users from “unfair, deceptive, and abusive” practices by lenders. Signed into law following the 2008 financial crisis, it fundamentally changed the relationship between banks and consumers.

Key Consumer Protections

1. Rate Hike Restrictions

  • 45-Day Notice: Banks must provide 45 days’ advance notice before increasing your interest rate or making significant changes to account terms.
  • First-Year Freeze: Lenders generally cannot increase the APR on a new account during the first 12 months.
  • Retroactive Protection: Rate increases generally apply only to new purchases, protecting your existing balance from sudden spikes (unless you are 60+ days late).

2. Fee Transparency and Limits

  • Late Fee Caps: Fees must be “reasonable and proportional” to the violation.
  • No Over-Limit Fees by Default: Banks cannot charge over-limit fees unless you specifically “opt-in” to allowing over-limit transactions.
  • Fee-Harvester Limits: For cards targeted at those with poor credit, total upfront fees cannot exceed 25% of the initial credit limit.

3. Payment and Billing Rules

  • Minimum Payment Warning: Every statement must show how long it will take to pay off the balance (and the total cost) if you only pay the minimum.
  • Standard Due Dates: Payments must be due on the same day each month, and banks must give you at least 21 days from the date the bill is mailed to pay it.
  • Fair Payment Allocation: If you have different APRs for different balances (e.g., a purchase vs. a balance transfer), any payment above the minimum must be applied to the highest-interest balance first.

The Role of the CFPB

While the Fed initially wrote the rules for the CARD Act, the Consumer Financial Protection Bureau (CFPB) is now the primary agency responsible for enforcing these rules and monitoring bank compliance.

Why It Matters Today

In a rising interest rate environment, the CARD Act is the only thing preventing banks from retroactively increasing the rates on your existing debt. While your Variable APR moves automatically with the Fed, your Bank Margin is protected by the 45-day notice requirement.
