CD Rates May 2026 Top 4.30% APY

The best certificate of deposit rates for May 2026 are holding steady between 4.10% and 4.30% APY, giving savors a narrow window to lock in returns above 4%. GECU currently leads the market for a 1-year term at 4.23% APY, while Sullivan Bank offers the top 5-year rate at 4.30% APY [1]. A survey of eight online banks conducted in mid-May found the average top rate across standard terms between 6 months and 5 years sits at roughly 4.10% APY [2].

The yield curve remains relatively flat, meaning investors gain little yield by extending their lock-up period. Bread Savings offers a uniform 3.85% APY across most terms, and LendingClub’s 11-month promotional rate at 4.15% beats many standard longer-term options [2]. This structure suggests that shorter terms or "odd-term" promotions often provide better value than long commitments. For those seeking liquidity without a lock-up, SoFi offers a high-yield savings account at 4.50% APY, though that rate is variable and subject to change [1].

CD rates loosely track the federal funds rate with a lag of 30 to 90 days, reflecting the Federal Reserve’s recent policy stance [2]. Large national banks like Chase, Bank of America, and Wells Fargo consistently offer lower rates than online banks and credit unions [1]. Institutions like E*TRADE offer competitive rates with no minimum deposit, while credit unions frequently provide higher yields known as share certificates [1][2]. All listed options carry FDIC or NCUA insurance, protecting deposits up to $250,000 per depositor [1].

The primary decision for savers is whether to lock in these fixed rates now or bet on a potential rate drop by utilizing shorter terms that offer similar yields.
