CD rates are determined by a stack of forces working together: the Federal Reserve’s benchmark rate sets the baseline cost of money, and each bank prices its certificates of deposit off that baseline according to inflation, its own need for deposits, the term you choose, and competition from other institutions. That is why two banks can post different rates on the same day for the same term, and why rates drift even when the Fed holds steady. As of March 2026, the federal funds target sits at 3.50% to 3.75%, national average one-year CDs pay about 1.89%, and the most competitive banks are above 4%.
The Federal Funds Rate Sets the Floor
The Federal Open Market Committee sets the federal funds rate, the interest rate banks charge each other for overnight loans of reserve balances at the Fed. That single number ripples through the whole system because it determines the base cost of money for every bank in the country. When the FOMC raises its target, banks pay more to borrow and, in turn, pay more to depositors to attract funds.
No law ties CD rates to the fed funds rate at any fixed ratio, but the benchmark acts as a gravitational center. A bank pricing far below the prevailing range would struggle to bring deposits in the door; one pricing far above it would squeeze its own margins. The prime rate, used as a reference for many consumer products, historically tracks about 300 basis points above the federal funds target.
The FOMC meets eight times a year on a published schedule and announces rate decisions at the end of each meeting. CD rates at most institutions shift within days or weeks of a move, and sometimes in advance when a change is widely expected. The current spread between the 3.50%–3.75% target and the 1.89% national one-year average shows how much room banks have to price below the benchmark when they don’t need to compete hard for deposits.
Inflation and Real Returns
Inflation is the silent competitor for every CD rate. If prices are rising at 3% a year and your CD pays 2%, your purchasing power is shrinking even as your balance grows. Banks watch the Consumer Price Index closely when setting rates, because depositors will move money into Treasury securities or high-yield savings accounts if CDs fall too far behind.
The number that matters is the real return, roughly the CD’s rate minus inflation. Savers who focus only on the nominal rate can end up worse off in real terms. This is why CD rates climbed sharply in 2022 and 2023 when inflation surged, and why they’ve eased as price growth has moderated.
Forecasts feed into pricing too. When analysts predict a recession, banks expect the Fed to cut and may lower CD offerings preemptively. During expansion, expectations of higher future rates tend to push current yields up as banks compete for the deposits they’ll need to fund growing loan demand.
Bank Funding Needs and Competition
Banks use your deposit to fund loans, and the spread between what they pay you and what they charge borrowers is where they make money. When loan demand is strong, banks need more deposits and raise CD rates to pull cash in. When loan activity slows, the incentive to offer generous rates fades.
Regulation also plays a role. Large national banks must meet a liquidity coverage ratio of at least 1.0 on each business day, holding enough high-quality liquid assets to cover projected outflows over a 30-day stress scenario. When a bank’s liquidity position tightens, raising CD rates is one of the fastest ways to shore up the balance sheet.
Competition explains the rest of the variation. Online banks consistently pay more than traditional brick-and-mortar institutions because they don’t carry the overhead of branches, leases, and teller staff, and they redirect those savings into yield. The gap can run 1.5 to 2 percentage points above the national averages, which are dragged down by large traditional banks. A smaller community bank might also post an aggressive rate during a seasonal lending surge or when it needs to grow deposits quickly.
Brokered CDs
Brokered CDs, sold through investment firms rather than directly by banks, often carry slightly higher rates than what the issuing bank offers at its own counter. The brokered market is more competitive because dozens of banks bid for deposits at the same time. These CDs carry FDIC insurance like direct bank CDs, subject to the standard $250,000 per-depositor, per-bank, per-ownership-category limit. If you hold brokered CDs from multiple banks through the same brokerage, you have to track each issuing bank separately to stay within coverage.
Term Length and the Yield Curve
Longer lock-up periods generally mean higher rates. A bank that can count on your money for five years has more flexibility in how it deploys the capital than one holding a three-month deposit, and the extra yield compensates you for giving up access.
Under normal conditions, plotting rates across maturities produces an upward-sloping yield curve: six-month CDs pay less than one-year, which pays less than five-year. The relationship isn’t mechanical, though. In early 2026, national averages show a flatter pattern, with one-year CDs at 1.89% and five-year CDs at 1.69%. Shorter terms are actually paying more.
This inverted pattern shows up when the market expects rates to fall. Banks don’t want to lock in high rates for five years if they believe the Fed will cut aggressively, so they price long-term CDs lower. They still need short-term deposits and will pay up for them. For savers, that creates an unusual window where shorter CDs offer better returns with less commitment. Whether the curve is normal or inverted should shape whether you lock in a long term or stay short and reinvest as conditions change.
Rate Versus APY
Two CDs can advertise the same interest rate and pay different amounts depending on how often they compound. A CD that compounds daily calculates interest on your balance every day, including on previously earned interest. One that compounds monthly runs that calculation only 12 times a year. The difference is small on a single CD and grows with larger balances and longer terms.
The number to compare across offers is the annual percentage yield, or APY, not the stated interest rate. APY accounts for compounding frequency and shows what you’ll actually earn over a year. A 4.00% rate compounded daily produces a slightly higher APY than the same rate compounded monthly or quarterly. When shopping, the APY is the apples-to-apples number.
