Why They Rise and Fall"},"content":{"rendered":"

One month a bank offers 5% on a CD; a year later the same bank offers 3.5%. Nothing about the bank changed \u2014 so what actually moves CD rates? Understanding the answer tells you when to lock, when to wait, and why the rate you’re offered today won’t last.<\/span><\/p>\n

Quick answer:<\/b> CD rates are driven mainly by the <\/span>Federal Reserve’s benchmark interest rate<\/b>. When the Fed raises rates, CD rates climb within weeks; when it cuts, they fall. On top of that, a bank’s need for deposits and the term length fine-tune the exact rate you’re offered. See what any rate earns with our free <\/span>CD rate calculator<\/span><\/a>.<\/span><\/p>\n

1. The Federal Reserve (the Biggest Factor)<\/b><\/h2>\n

The Fed sets the federal funds rate \u2014 the rate banks charge each other for overnight loans. It’s the anchor for nearly every short-term rate in the economy, including CDs. <\/span><\/p>\n

When the Fed hikes to fight inflation, banks can earn more lending money, so they raise CD rates to attract deposits. <\/span><\/p>\n

When the Fed cuts to support the economy, CD rates drop. <\/span><\/p>\n

This is why CD rates moved from near-zero in 2021 to 5%+ in 2023 \u2014 the Fed’s fastest hiking cycle in decades. Track the pattern in our <\/span>historical CD rates guide<\/span><\/a>.<\/span><\/p>\n

2. The Bank’s Need for Deposits<\/b><\/h2>\n

Banks fund their lending with deposits. A bank aggressively growing its loan book needs cash, so it offers above-market CD rates to pull it in. <\/span><\/p>\n

A bank already flush with deposits has no reason to compete, so it pays the bare minimum. <\/span><\/p>\n

This is why <\/span>online banks usually beat brick-and-mortar banks<\/b> \u2014 they have lower costs and often want deposits more, so they pass higher rates to you. It’s also why shopping around can find a rate a full percentage point above the national average.<\/span><\/p>\n

3. The Term Length<\/b><\/h2>\n

Normally, longer terms pay higher rates \u2014 the bank rewards you for committing money longer. But not always. <\/span><\/p>\n

When markets expect the Fed to cut soon, banks sometimes pay <\/span>more<\/span><\/i> on short CDs than long ones (an “inverted” curve), because they don’t want to lock in high rates for years. <\/span><\/p>\n

That’s why a 6-month CD occasionally beats a 5-year CD \u2014 the market is pricing in future cuts. Compare terms with our <\/span>CD comparison calculator<\/span><\/a>.<\/span><\/p>\n

4. Promotions and Odd Terms<\/b><\/h2>\n

Banks use non-standard terms \u2014 7, 9, 11, 13 months \u2014 for promotional offers to attract new money. These promos often beat the bank’s own standard rates, but they usually renew into a mediocre standard term, so watch the <\/span>auto-renewal<\/span><\/a>.<\/span><\/p>\n

Why Are CD Rates “So Low” (or High)?<\/b><\/h2>\n

It depends entirely on your reference point. Compared to the 2010s (near zero), today’s mid-4% rates are excellent. Compared to 1981 (17%+), they’re modest. <\/span><\/p>\n

The honest measure is <\/span>the rate minus inflation<\/b> \u2014 a 4.5% CD against 3% inflation gives a ~1.5% real return, which is historically respectable. When people say rates are “low,” they’re often comparing to a recent peak, not to history.<\/span><\/p>\n
