Bank Rate, currently 3.75%, is the reference point for most UK rates. Last reviewed: 1 July 2026 | MONEY GUIDES | | ------------ | Interest is the cost of borrowing money, or the reward for saving it, expressed as a percentage of the amount involved. In the UK, most lending and savings rates are set with reference to the Bank of England's Bank Rate, currently 3.75%. | KEY FACTS A lending rate is what a borrower is charged; a savings rate is what a saver earns.Bank Rate, set by the Bank of England, is the main reference point for UK rates.Higher rates generally discourage borrowing and encourage saving; lower rates do the opposite.Not every rate moves in step with Bank Rate: fixed products react to swap rates instead. | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ## How lending rates and savings rates relate to each other If someone borrows £100 at a 5% annual lending rate, they owe £105 a year later. If someone saves £100 in an account paying 5% a year, they have £105 a year later. The mechanics are identical; the direction of who pays whom is reversed. How different products relate to Bank Rate | Rate Type | Who Pays Whom | Typical Link to Bank Rate | | ----------------------- | -------------------- | ----------------------------------- | | Tracker mortgage | Borrower pays lender | Direct, contractual | | Fixed mortgage | Borrower pays lender | Indirect, via swap rates | | Easy access savings | Bank pays saver | Tends to track over time | | Fixed-rate savings bond | Bank pays saver | Locked at opening, unaffected after | ## Why interest rates change the wider economy, not just individual accounts When rates rise, borrowing becomes more expensive and saving becomes more rewarding, which tends to reduce how much people and businesses spend. When rates fall, the reverse tends to happen. The Bank of England uses this mechanism deliberately, adjusting Bank Rate to try to keep inflation close to its 2% target. | Worked Example: Same rate, opposite effect A person with a £10,000 personal loan at 8% pays roughly £800 a year in interest. A person with £10,000 in a savings account at 4% earns roughly £400 a year. Both figures move if the underlying rate environment shifts, but in opposite directions for the borrower and the saver. | | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | This article is general information, not financial or legal advice.

Fixed mortgage pricing is driven by swap rates, which reflect market expectations of future Bank Rate movements. Lenders can reprice fixed deals in anticipation of a decision, before the Monetary Policy Committee has actually met. | Related Guides [What Is the Bank of England Bank Rate?](https://www.kaeltripton.com/what-is-the-bank-of-england-bank-rate/)[What Is Inflation?](https://www.kaeltripton.com/what-is-inflation-uk/) | | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Sources [Bank of England: Interest rates and Bank Rate](https://www.bankofengland.co.uk/monetary-policy/the-interest-rate-bank-rate?ref=kaeltripton.com) | | -------------------------------------------------------------------------------------------------------------------------------------------------------- | | Update 6 November 2026: Bank Rate raised to 4%The Bank of England raised Bank Rate from 3.75% to 4% on 5 November 2026, the first increase since August 2023\.
