CD rates broadly track the federal funds rate, but that only sets the backdrop. The spread between banks comes from how badly each needs deposits, its cost structure, the term you pick, and whether the offer is a promotional product designed to win new customers.

The policy rate sets a ceiling, not a specific price
The federal funds rate is what banks charge each other overnight, and it anchors the general cost of money in the economy. When it rises, the return banks are willing to pay you for a deposit tends to rise too, because deposits are one of several ways a bank funds its lending, and it competes against those other sources. When it falls, deposit rates follow, typically with a lag rather than moving in lockstep.
None of that sets the number on any single bank's rate sheet. It sets the range those numbers cluster around. Two banks operating under the identical policy-rate backdrop can quote 12-month CDs a full two percentage points apart, and the policy rate explains none of that gap.
The shape of the yield curve decides which term pays most
Rates are not one number, they are a curve across terms, and its shape reflects what the market expects rates to do next. When the market expects rates to hold or rise, longer terms typically pay more, compensating you for locking up money for longer. When the market expects rates to fall, the curve can invert: short CDs pay more than long ones, because a bank that sees rate cuts ahead does not want to guarantee today's higher rate for years.
That inversion is the reason longer always pays more is not a reliable rule. Check the actual rate at each term on offer rather than assuming the curve slopes the way it usually does. An inverted curve is also a signal worth noting on its own, since it reflects what the broader market expects, not just what one bank happens to be offering.
A bank's own appetite for deposits matters more day to day
A bank growing its loan book needs funding to support those loans, and a CD is one of the cheaper ways to raise it, so that bank will pay up to attract deposits. A bank sitting on more deposits than it can profitably lend out has no reason to compete on rate at all, and its CD sheet will sit well below the market's better offers regardless of what the Fed is doing. This single factor, how badly a specific institution wants your money right now, explains more of the day-to-day spread than the policy rate does.
That funding need can also shift quickly. A bank expanding into a new region or pushing a new lending product may run an aggressive CD promotion for a few months and then quietly let it lapse once the funding target is met, which is one reason the same bank's rate sheet can look completely different from one quarter to the next.
A worked comparison of two real offers
Suppose two banks both quote a 12-month CD, compounded daily, on the same $10,000 deposit. Bank A, sitting on excess deposits, offers 3.50% APY: $10,000 matures at $10,350, a flat $350 of interest. Bank B, actively competing for new funding, offers 4.50% APY: $10,000 matures at $10,450, a flat $450 of interest. Same deposit, same term, the same insurance protection either way, and a $100 difference in outcome that has nothing to do with risk and everything to do with which bank you picked.
Overhead explains why online banks consistently pay more
A bank with a branch network is funding rent, staff and cash logistics at every location, and that cost has to come from somewhere, often from paying less on deposits. An online-only bank skips that cost structure entirely and routinely passes the saving through as a higher rate, since rate is close to the only lever it has to compete for customers who will never walk into a branch.
Promotional and odd terms are priced to resist comparison
A 7-month or 13-month CD does not sit on the standard rate table next to the usual 6- and 12-month columns, which gives a bank room to price it aggressively as a new-customer offer without repricing its entire standard lineup. For the saver willing to treat it as a one-off rather than a recurring rate, that odd term is frequently the best number on the page.
A rate that looks unusually high relative to the rest of a bank's sheet is worth a second look rather than automatic suspicion. It is far more often a genuine promotional push for deposits than a sign of trouble, since FDIC insurance protects the deposit regardless of why the bank is offering an attractive rate.
What the national average rate is actually telling you
A widely quoted national average CD rate is dragged down by large banks with big branch networks and deposits they do not need to chase, so it understates what a competitive institution is currently paying. Treat it as a floor to beat, not a benchmark to be satisfied with, and compare against the actual best rate available to you for your term and balance instead. Pull the current rate for your specific deposit at three or four institutions, including at least one online bank and one credit union, rather than relying on a single average figure.
Sering ditanyakan
No. The policy rate sets the environment, but each bank prices its own deposits against its funding needs and its competition, so the relationship is directional rather than mechanical. A bank flush with deposits has little reason to pay up and may lag a policy increase for months; one trying to grow its balance sheet may lead. That is why online banks and credit unions competing hardest for deposits frequently pay well above large branch networks for the same term at the same moment. Timing is asymmetric too: rates tend to fall quickly when cuts are expected and rise slowly afterwards, because deposits are a cost. The practical takeaway is to compare actual quoted APYs across institutions rather than inferring what you should be getting from the policy rate.
