## Key takeaways

- Tracker mortgages and many savings accounts move within days of a base rate change, while fixed-rate deals only reprice when they expire.
- Banks pass rate rises to borrowers faster than to savers, and the gap between those speeds is a large part of their margin.
- The full effect of a rate decision takes 18 months to two years to work through the economy, which is why the Bank acts on forecasts rather than current inflation.

Eight times a year, the Bank of England's Monetary Policy Committee votes on the base rate, and the announcement is compressed into a single headline number. What that number does to an individual household depends almost entirely on which financial products they hold and when they took them out.

The fastest transmission is through tracker mortgages, which are contractually pegged to the base rate and usually move within a billing cycle. Standard variable rates follow at the lender's discretion, typically within weeks. The slowest channel is the fixed-rate mortgage. A household two years into a five-year fix feels nothing at all until the deal expires, at which point the accumulated change arrives in one jump. This is why economists talk about rate decisions working with "long and variable lags": millions of fixes expire on different dates, so a single decision drips into the economy over years.

Savings rates travel the same road in the other direction, and noticeably more slowly. Banks have long been criticised for repricing loans faster than deposits, and the difference between those two speeds is a meaningful part of their net interest margin. Easy-access accounts often lag a rate rise by months, while fixed-term savings bonds reflect market expectations of future rates rather than the current base rate itself.

## Beyond mortgages and savings

The base rate also shapes prices that never mention it. Credit card and overdraft rates sit far above it but drift with it. Business loans reprice quickly, which feeds into what firms charge customers. Annuity rates and pension transfer values move with long-term interest rates, which respond to where markets think the base rate is heading rather than where it is today.

That last point explains a common confusion. Fixed mortgage deals sometimes fall while the base rate holds steady, or rise before any announcement. Lenders price fixes from swap rates, which are the market's forecast of the base rate over the life of the deal. By the time the committee votes, the expected decision is usually already in the price.

For households, the practical lesson is to know your own transmission speed. Anyone on a tracker should stress-test their budget against further movement in either direction. Anyone approaching the end of a fix can usually lock a new deal three to six months early, keeping the option to switch if pricing improves before completion. Savers holding cash in an account that never seems to move have the strongest case of all for shopping around, because the lag on deposits is the one part of the system that rewards attention.
