There is no single delay. Financial markets can react quickly to a central bank’s decision or to expectations about its next move, but banks and other lenders pass those changes on to customers unevenly—over weeks or months, by different amounts, or only when a product resets. Your country, provider, product and contract terms determine what happens to your rate.
Why a central bank’s move does not instantly change your rate
Markets may move before the announcement
A policy rate generally sets the price of overnight or short-term money; it is not the rate customers directly pay on a mortgage or earn in a savings account. Markets also price expectations of future policy into longer-term rates. As a result, mortgage and other market rates may shift ahead of an announced policy change. The Bank of England says this initial market stage typically happens relatively quickly when financial markets are stable: its explanation of monetary policy transmission.
Lenders set customer rates using other factors
Retail rates reflect more than the central bank’s policy rate. Lenders consider market benchmarks, their own funding costs, competition, credit risk, leverage and wider credit conditions. A policy-rate change therefore does not guarantee an equal or immediate change in each borrowing or savings rate.
Products and contracts determine the remaining delay
Variable-rate products can be repriced sooner, depending on their stated benchmark, terms and provider decisions. Fixed-term products may be priced using market rates when offered, but an existing borrower’s scheduled payment usually does not change until the fixed term ends or the borrower refinances. Deposits and unsecured credit may adjust gradually or slowly.

How quickly different products can respond
| Product | What may move first | What to check |
|---|---|---|
| Savings account | A provider may change a variable rate after market rates move, but pass-through can be gradual or limited. | Whether the rate is fixed or variable; any bonus period or notice requirement; and the provider’s rate-change terms. |
| New fixed-rate mortgage | The rate offered on a new deal can respond to longer-term market rates and expectations, sometimes before a policy decision. | The deal’s offer date, rate validity and eligibility conditions. |
| Existing fixed-rate mortgage | The borrower’s scheduled rate generally stays in place during the fixed term. | The fixed-term end date and any refinancing or reset provisions in the contract. |
| Variable-rate mortgage | The rate may change sooner if its benchmark or the lender’s terms provide for it. | The named benchmark, adjustment rules and next reset date. |
| Personal loan or credit card | Rates may track policy changes less closely because unsecured borrowing includes wider credit spreads. | Whether the rate is fixed or variable and the agreement’s repricing terms. |
What UK evidence shows about pass-through
UK examples illustrate why a policy-rate move is not a one-for-one promise. After the Bank of England cut Bank Rate by 25 basis points in August 2024, the average quoted rate on UK instant-access deposits had fallen by 11 basis points by October 2024—slightly less than half the policy-rate reduction, according to the Bank’s November 2024 Monetary Policy Report.
In its February 2026 Monetary Policy Report, the Bank described pass-through to sight deposits as low and gradual. It also reported that quoted personal loan rates had eased slightly while credit-card rates remained close to recent highs, consistent with slower adjustment. These are UK market observations from those reports, not forecasts for a particular account, loan or country.

The timing of mortgage changes also depends on how borrowers are financed. The Bank reported in its August 2024 Monetary Policy Report that about 85% of UK mortgages were on fixed terms. That is a dated UK statistic, not a current global estimate; it helps explain why a policy move may leave many existing mortgage payments unchanged until a deal ends.
How to find out when your own rate could change
- Identify your country and product. The relevant central-bank rate and local lending conventions differ by country.
- Check whether your rate is fixed or variable. For a variable rate, find the benchmark or provider discretion stated in the agreement. For a fixed rate, note the term-end date.
- Look for the adjustment or reset terms. Review your account or loan agreement for notice periods, repricing rules, bonus periods and any limits on changes.
- Ask the provider about the next applicable date. A central-bank announcement alone does not establish when your individual account or payment will change.
Rate changes and the wider economy follow different timelines
A market rate or customer rate can begin moving well before monetary policy has had its full effect on household spending, business activity and inflation. A 1999 Bank of England explanation estimated that a policy change’s peak effect on demand and production could take up to about a year, with fuller effects on inflation taking up to a further year. Those are historical estimates about broad economic effects, not a current forecast or a timetable for an individual product. The Bank’s 1999 explanation also noted that in some cases it could be several months before official rate changes affected payments made by some mortgage holders or received by savings deposit holders.
