As of September 1, 2026, the highest-yielding one-year certificate of deposit (CD) available to consumers offers an annual percentage yield (APY) of 4.35%. This rate stands a remarkable 2.64 percentage points above the FDIC's national average of 1.71% for the same term. For a saver depositing $10,000, this difference translates into an extra $264 in interest over a year—$435 at the top rate versus just $171 at the average.
The Federal Reserve's current target range for the federal funds rate, 3.50% to 3.75%, continues to anchor the deposit-pricing landscape. With the Fed holding steady since its July meeting, banks and credit unions are competing aggressively for deposits, particularly at the shorter end of the maturity curve.
September's Deposit Rate Snapshot
Across the broader CD market, the highest APY observed on September 1 was 4.50%, available on select three-, four-, and five-year terms. The one-year leader pays 4.35%, while the Fed's target ceiling sits at 3.75%. In contrast, the FDIC's average for a 12-month CD is just 1.71%, illustrating a wide dispersion between the best available rates and what most savers actually receive.
The Inverted Yield Curve
Notably, the national average CD curve is inverted, with the 12-month maturity offering the highest average yield (1.71%) and longer terms generally lower: 1.57% for two years, 1.34% for three years, 1.27% for four years, and 1.36% for five years. Even the shortest terms lag, with one-month at 0.22%, three-month at 1.14%, and six-month at 1.41%.
This inversion removes the traditional reward for locking up funds for longer periods. It also means that diligent savers who shop around can secure significantly better returns than the deposit-weighted average suggests.
Bank Profitability and Deposit Costs
Industry data underscores the selective nature of deposit pricing. In the second quarter, banks' net interest margin edged up to 3.32%, while domestic deposits grew by 0.8%. Quarterly bank profits reached $90.1 billion. This suggests that institutions are willing to pay up for targeted funding without repricing their entire deposit base, a strategy that benefits savers who are willing to compare offers.
What Savers Should Consider
While the headline APY is attractive, terms and conditions matter. The Consumer Financial Protection Bureau warns that early withdrawals typically trigger penalties, which can erode returns. Savers should compare maturity dates, APYs, and penalty schedules before committing. Additionally, federal deposit insurance covers up to $250,000 per depositor, per insured bank, per ownership category, so it's wise to stay within these limits.
The Federal Reserve's next policy decision is scheduled for September 16. Any shift in the target range could influence future CD rates, but for now, the competitive edge for one-year CDs remains substantial.
As the market stands, the spread between the best and average CD rates is the key signal: while funding costs are low on average, the most attractive offers are still priced aggressively. For savers, this means that taking a few minutes to shop for the highest APY can yield outsized rewards.
