How Does Bank Rate Affect the Value of the Pound?

Bank Rate is 3.75%, and the Bank of England says higher interest rates can increase the value of the pound compared to other currencies¹. That single sentence is the whole of the direct link between the two. Bank Rate is not set to manage the exchange rate, and the pound moves on far more than one announcement.

What the link means in practice is that when UK interest rates look more attractive relative to rates elsewhere, money tends to move towards sterling, and the pound can strengthen. When rates are cut, or when markets expect cuts, that pull weakens. The effect is rarely clean or immediate, and it can be reversed within days by inflation figures, jobs data or events overseas.

For a household, the pound's value shows up in three places: the cost of holiday money and anything bought in another currency, the interest earned on savings, and the interest paid on variable-rate borrowing. This page sets out how each of those works, how Bank Rate reached 3.75%, and what happens next.

Bank Rate: 3.75% and what it is

Bank Rate is the rate of interest the Bank of England pays to commercial banks, building societies and financial institutions that hold money with it⁵. It is the core interest rate in the UK, and setting it is the Bank's job⁶. Because those institutions can earn Bank Rate by leaving money with the Bank of England, it sets the floor against which they price their own lending and savings.

It is 3.75% now, following the decision on 17 September 2026¹. Barclays describes it in the same terms: the rate the Bank of England charges other banks and other lenders when they borrow money, currently 3.75%⁷. The Monetary Policy Committee voted to hold the base rate at 3.75% at that meeting⁸.

The rate applies to institutions, not to you directly. What reaches your household is the second-round effect: the interest a bank pays on your savings, the rate on a variable mortgage, the cost of an overdraft. A variable rate can change at any point, typically reflecting a change in Bank Rate⁹.

Bank Rate is also not the only thing that sets the price of borrowing. Lenders price fixed mortgage deals off swap rates and gilt yields, which move on expectations of future Bank Rate rather than the current level, so a fixed deal can get more expensive even on a day when Bank Rate is held.

Higher rates can strengthen the pound

The Bank of England states the mechanism plainly: higher interest rates can also increase the value of the pound compared to other currencies³. HSBC puts it the same way: higher interest rates can increase a currency's value¹⁰.

The reasoning is about relative returns. If sterling deposits pay more than deposits in another currency, holding sterling becomes more attractive, demand for it rises, and its price in other currencies tends to rise with it. The reverse applies when UK rates fall or when markets expect them to fall faster than rates elsewhere.

Two qualifications matter for anyone planning around this. First, the Bank of England does not set Bank Rate to manage the pound. Its remit is inflation, and higher rates work on prices by reducing how much money is spent in the UK³. The currency effect is a by-product, not the target. Second, exchange rates respond to expectations as much as decisions. A hold that was widely expected can move sterling less than the wording of the announcement that follows it.

How Bank Rate has moved: from 0.1% to 5.25% and back down

The recent cycle is the clearest illustration of how far and how fast Bank Rate can travel. The Bank of England interest rate rose from 0.1% in December 2021 to 5.25% in August 2023⁴. Over that period the Bank raised interest rates 14 consecutive times¹¹, and the bank rate was increased 13 times from 0.25% to 5.25% between January 2022 and August 2023¹².

The peak of 5.25% in August 2023 is the figure to remember for the recent period¹¹. It is not the highest Bank Rate on record. In the years between 1975 and 2007, Bank Rate was 3.5% at its lowest point and 17% at its highest¹.

The descent since then has been gradual. The Bank of England reduced interest rates twice in 2024, in August and November, from 5.25% to 4.75%¹¹. In 2024 the base rate was cut four times, each by 0.25 percentage points, in February, May, August and December¹⁴. Interest rates were then lowered three times in 2025 by the Monetary Policy Committee, from 4.75% to 4%¹⁵. The Financial Ombudsman Service's own worked example of compensation interest shows the path in steps: 4.75% from 15 January 2025 to 5 February 2025, 4.50% from 6 February 2025 to 7 May 2025, and 4.25% from 8 May 2025 to 6 August 2025¹⁶.

What a Bank Rate change means for your borrowing, savings and holiday money

Borrowing. A base rate change affects existing lending customers with overdrafts or loans linked to the Bank of England base rate¹⁷. Where a loan is on a variable rate, a rise means you are likely to pay more interest on what you have borrowed¹⁸. Tracker products move fastest: Virgin Money's Current Account Tracker terms say changes in Bank Rate may be made at any time and will normally be applied on the same or the next business day¹⁹. Mortgage lenders have more room. Afin Bank says it will give notice of any change to Bank Rate and to your monthly payment within a reasonable time after the change, and that changes take effect immediately and may be notified after they have affected your monthly payment²⁰.

Savings. Banks set their own savings rates, and they do not have to follow Bank Rate. NS&I says its Direct ISA rate is variable and can be changed up or down from time to time, for example when the Bank of England base rate changes or when rates in the general savings market change²¹. Halifax says that for savings you might have with your bank, you could see an increase in the amount of interest you earn¹⁸, and that it might review the interest rate if Bank Rate changes²². Lloyds Bank's Easy Saver terms say the rate can change over time and may be reviewed if Bank Rate changes²².

Holiday money. This is where the currency link becomes concrete. A stronger pound buys more foreign currency for the same number of pounds, so the same holiday costs less in sterling terms. A weaker pound does the opposite. The rate you actually get also depends on the provider's margin, any commission and the day you transact, which is why the timing of one Bank Rate decision is a small part of the total cost.

Fixed or tracker: how each one behaves

The choice between a fixed and a variable rate is really a choice about who carries the risk of Bank Rate moving.

For anyone whose fixed deal is ending, the relevant question is not what Bank Rate is today but what deals cost now. Independent guidance notes that the base rate was forecast to be cut in March, which would put downward pressure on rates in the medium term²⁶, but forecasts change and are not commitments.

Where the pound's value reaches your money

The exchange rate is not a single number that applies to everyone. It depends on what you are doing.

• Buying holiday cash or loading a travel card: the rate offered by the provider, less any commission or fee.
• Spending on a card abroad: the card scheme's rate on the day, plus any non-sterling transaction fee your card charges.
• Sending money overseas: the provider's exchange rate plus its transfer fee, which together make up the total cost.
• Receiving income in another currency: the rate on the day the money is converted.

Because each of these has its own margin, two people changing the same amount on the same day can get different outcomes. The Bank Rate decision moves the underlying market rate; the provider's margin decides how much of that movement reaches you.

Next decision: Thursday 5 November

The Bank of England will announce its next decision on Thursday 5 November 2026¹. The Monetary Policy Committee's next meeting is scheduled for that date²⁷, and the next review is due on 5 November 2026⁸.

There is a conflict in the published material about the timetable. One Bank of England page gives the next decision as Thursday 5 November 2026¹, while another gives 17 September 2026²⁸. One provider page gives 5 November 2026⁸ and another gives 5 October 2026⁶.

On frequency, the sources also differ. Independent guidance says the base rate is usually voted on by the Monetary Policy Committee eight times a year², while the Bank of England describes making its decision on interest rates every six weeks or so¹. The two descriptions do not match exactly.

Bank Rate has been kept unchanged at 3.75% at the last four Monetary Policy Committee meetings²⁹. The decision is based on the financial state of the UK economy, including inflation, employment figures and consumer confidence³⁰. The Bank of England does not publish a forecast path for Bank Rate, so any expectation of a rise or a cut is a market or commentator view, not a commitment.

What protects you if a rate move goes wrong

The rules that matter here are about how a change is communicated and what you can do if it is not.

• Notice of changes. Lenders set their own notice terms. Afin Bank's terms say it will give notice of any change to Bank Rate and to your monthly payment within a reasonable time after the change²⁰.
• Variable rate terms. NS&I's Direct ISA terms state the rate is variable and can be changed up or down from time to time²¹.
• Complaints. If you are unhappy with how a firm has applied a rate change, you can complain to the firm first and then take the complaint to the Financial Ombudsman Service if it is not resolved.
• Compensation interest. From 1 January 2026, the Financial Ombudsman Service's compensation interest rate will track the Bank of England's base (average) rate plus 1%³¹.

Where the protection stops: Bank Rate itself is not a consumer protection. It is a monetary policy tool. Nothing in the rules guarantees that a savings rate will rise when Bank Rate rises, or that a mortgage rate will fall when Bank Rate falls. Standard variable rates can be influenced by Bank Rate without having to follow it²³.
