Rate History and Federal Reserve Tracking

Both Discover and Capital One track their savings rates closely with the federal funds rate. When the Fed raised rates from 2022 through 2024, both banks increased their APY in lockstep. As the Fed has begun cutting rates in late 2025 and early 2026, both have lowered their rates accordingly.

Historically, Discover has maintained a slight edge of 0.10% to 0.20% over Capital One. This pattern has held consistently over the past three years, suggesting Discover prioritizes rate competitiveness slightly more than Capital One, which invests more in physical presence and technology.

If rates continue declining through 2026 as expected, both accounts will likely settle in the 3.50% to 4.00% APY range by year end. The relative gap should remain similar.

Frequently Asked Questions

Is the 0.15% APY difference between Discover and Capital One significant?

On a $25,000 balance, the 0.15% difference equals $37.50 per year. On $100,000, it equals $150 per year. For most savers, this is a marginal difference. Account features, customer service, and convenience should weigh more heavily in your decision than a fraction of a percent.
