Deposit betas, and why your savings rate moves slower than the base rate
Banks pass rate changes through at different speeds. Understanding deposit beta helps explain what happens to your savings return next.
What deposit beta means
It describes how much of a market-rate move is passed to depositors. A lower beta means the account rate changes less than the underlying benchmark.
Why products differ
Competition, funding needs, account behavior and product design all influence how quickly rates move. Two accounts at the same bank can behave differently.
What to watch
Look beyond the introductory rate. Check the ongoing rate, balance tiers, fees and notice requirements before switching.
