How the Bank of England base rate affects savings

The Bank of England base rate, also called Bank Rate, is the single most important interest rate in the UK, and it is the rate the Bank of England itself sets¹. It stands at 3.75% and has been at this level since December 2025². For a saver, the interest rate on an account tells you how much money will be paid into your account, as a percentage of your savings¹, and the base rate is one of the main influences on where those savings rates sit.

The important thing to understand is that the base rate does not automatically change what your savings earn. Only a small group of accounts, known as trackers, are contractually tied to it. For everything else, your provider decides whether and when to respond, and it is free to move rates by any amount, or not at all. This page explains how the base rate is set, how decisions pass through to savings rates, how different types of account respond, and what you can do when rates change.

What the base rate is and who sets it

The base rate is the core interest rate in the UK, and setting it is the Bank of England's job¹. The Bank sets an interest "base rate" for the whole of the UK⁸, and it is the rate at which the Bank lends to other banks, which is why it ripples out into almost every other interest rate in the economy, from mortgages and loans to savings accounts.

The rate itself is set each month by the Monetary Policy Committee (MPC), with the aim of keeping inflation at about 2%⁹. More precisely, the MPC aims to keep inflation as close as possible to the target of 2%². The committee is a group of nine people with a variety of backgrounds, responsible for setting Bank Rate⁴. The membership structure is set out in the Bank of England Act 1998, and the wider structure in the Bank of England and Financial Services Act 2016⁵.

The MPC's purpose is not to reward savers or help borrowers directly. Its objective is to keep inflation low and steady, aiming for the Government's 2% target¹⁰. When the MPC raises the base rate, borrowing becomes more expensive and saving becomes more attractive, which tends to reduce spending in the economy and, over time, the pace of price rises. When it cuts, the effect runs the other way. Savings rates are a consequence of that machinery, not its target.

The base rate is 3.75% and has been held since December 2025

The base rate currently stands at 3.75%, and it has been at this level since December 2025². As of September 2026, the MPC had voted 6-3 in favour of holding the base rate for the sixth month in a row⁷, so the rate has been unchanged for half a year.

The hold follows a long period in which the direction was downwards. Four base rate cuts in 2025, in February, May, August and December, helped push rates down from their peak¹¹. Before that, 2024 saw the base rate cut four times, each by 0.25 percentage points, in February, May, August and December².

What happens next is genuinely uncertain. The Bank of England indicated in early 2026 that it would continue to slowly reduce the base rate during the year, with it possibly stabilising by the end of the year¹¹, and a forecast from the Office for Budget Responsibility, the government's independent economic watchdog, predicted the base rate would stabilise in 2026¹². But the recent 6-3 votes show the committee is divided, and a forecast is not a promise. Savers should treat predictions of cuts as possibilities, not certainties.

How a base rate change reaches your savings rate

A base rate change reaches your savings account through one of three routes, depending on the type of account you hold. Understanding which route applies to you is the key to knowing what any headline rate decision actually means for your money.

For a tracker account, the link is contractual. The rate is defined as following the base rate, so a decision by the MPC passes through automatically under the account's terms⁶. For an ordinary variable account, there is no automatic link at all. HSBC, for example, states that its savings accounts are not directly linked to the base rate, so there is no immediate change when the base rate moves, but the bank reviews its rates after a base rate change¹³. NS&I says the same about its Direct Saver: the 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 change¹⁴. For a fixed-rate account, nothing happens at all until the term ends: the rate is fixed for the agreed period regardless of what the MPC does.

The same principle applies to borrowing, which is worth knowing if you have both savings and debts. A variable rate on a loan can change at any point, typically reflecting a change in the Bank of England's base rate¹⁵. Standard variable rates on mortgages can be influenced by changes in the base rate, and lenders often increase their SVR in the days and weeks after a base rate rise¹⁶, but each lender sets its own SVR at whatever level it wants¹⁶. The pass-through is faster and more complete on the borrowing side than on the savings side, which is a long-standing source of complaint from consumer groups.

There are also rules about how you are told. A firm should inform a banking customer of the current rate of interest that applies to a savings account on the telephone or in a branch, at the customer's request¹⁷. And under the Payment Services Regulations 2017, changes in interest rates may be applied immediately and without notice where they are based on reference rates provided to the user, or where the change is more favourable to the user¹⁸. That is why a tracker can move without waiting for a letter.

Variable, fixed and tracker savings: how each one responds

The three types of account respond to a base rate change in completely different ways, and the differences matter when you are choosing where to put money.

Tracker accounts are the only savings products with a built-in link. A tracker rate is a type of variable rate that tracks a base rate, such as the Bank of England base rate, for either a set period or an open period of time²⁰. On the savings side, MoneyHelper describes tracker bonds that track a particular index or rate, for example inflation or the Bank of England base rate, over a set period from six months to five years¹⁹. The Co-operative Bank's Base Rate Tracker Savings Account is a variable easy access account that tracks the Bank of England base rate, with its rate set a fixed margin below the base rate⁶.

Variable accounts, which include most easy access accounts, are the most common type and the least predictable. The provider can change the rate at any time, and the base rate is only one influence among several. NS&I's Direct Saver wording is typical: the rate can change when the base rate changes, or when rates in the general savings market change¹⁴. A provider is equally free not to pass on a rise.

Fixed-rate accounts are unaffected by base rate decisions during their term. The trade-off is access: your money is locked away, and the rate you signed up for is the rate you get, whether the base rate later rises or falls. When the term ends, the account matures and you choose what to do next, at which point the prevailing base rate matters again.

A cut does not always mean a lower rate straight away

When the base rate falls, savings rates tend to follow, but not instantly and not uniformly. After the base rate cut of 6 February 2025, the average instant-access savings rate dropped by 0.13 percentage points²¹, a move that took weeks to feed through and was smaller than the cut itself.

Providers move at different speeds and by different amounts. HSBC states that its savings accounts are not directly linked to the base rate, so a base rate change brings no immediate change to savings rates, though rates are reviewed afterwards¹³. NS&I reserves the right to change its variable rates when either the base rate or the wider savings market moves¹⁴, which means its rates can change even when the MPC has held the base rate, and can stay put even after a cut.

Tracker accounts have their own notice rules, and these differ depending on the direction of the change. Under the Co-operative Bank's Base Rate Tracker terms, the new interest rate applies without notice, no more than 14 business days following a base rate change⁶. For a change that increases the rate, the bank tells customers within 30 days after it has happened. For a change that decreases the rate, customers get personal notice at least two months before the change is made⁶. So a tracker can fall before you receive the letter telling you about it, but a rise applies just as quickly.

The practical lesson is to check your own account's terms rather than assume. The summary box that comes with every savings account states whether the rate is variable or fixed and what notice the provider must give. The FCA's rules require a firm to tell you the current rate of interest on your savings account on request, by phone or in branch¹⁷, so you can always ask directly. Our guide to reading a savings summary box explains each part, and when a savings provider changes your rate covers your rights when a cut is announced.

How the base rate has moved: from rises to cuts

The base rate has been on a full round trip over the past five years, from near zero to a multi-decade high and most of the way back down. Understanding that history helps explain why savings rates are where they are today.

The starting point was extraordinarily low. Since December 2021, Bank Rate increased from 0.1% to 5%²². The rises came fast: the Bank Rate went from 0.1% to 1.25% by July 2022²³, and the Bank of England raised the base rate eight times in 2022²⁸. Over the tax year 2022 to 2023, the base rate increased from 0.75% to 4.25%²⁴. The peak was 5.25%, the level Bank Rate reached from August 2023²⁵. For context, the base rate was 0.5% in 2014²⁹, and the 7.5% level that applied for some time in 1998 was described as a twenty-year high when that consultation was written²⁹.

Then came the cuts. In 2024 the base rate was cut four times, each by 0.25 percentage points, in February, May, August and December². In February 2025 the Bank lowered the base rate from 4.75% to 4.5%²⁶. Four further cuts followed in 2025, in February, May, August and December¹¹, bringing the rate to 3.75%, where it has stayed since December 2025². As of September 2026 the MPC had held the rate for the sixth month in a row⁷.

The pattern has not been smooth. Decisions have sometimes been close: in March 2025 the nine-person MPC voted 8-1 to keep the rate unchanged, with one member voting for a cut to 4.25%²¹, and in July 2025 the vote was 6-3¹². The MPC concluded at one point that "a gradual and careful approach [to reducing the base rate] is appropriate"²¹. For savers, the lesson of this period is that the base rate can move quickly in both directions, and that long holds, like the current one, can end abruptly.

When the Monetary Policy Committee decides

The MPC meets to look at the evidence and make a decision about every six weeks⁴, which works out at eight scheduled decisions a year³. The decision, with minutes of the meeting, is published at midday on the Thursday at the end of each meeting week⁵. Each of the nine members has a vote, and the split is published, which is how markets gauge how likely the next change is²¹.

The committee also has the power to make unscheduled changes to the base rate if it thinks it necessary³. This is not theoretical: the MPC used this power in March 2020, when it reduced the base rate due to the potential effects of the coronavirus on the economy². Unscheduled moves are rare, but savers should know they can happen outside the normal calendar.

As for the next decision, the recent reporting disagrees with itself, and it is worth being honest about that. One source dated 17 September 2026 says the next MPC meeting is scheduled for Thursday 5 November, with one further meeting this year in December⁷. Another, from the same month, gives the Bank's next rate decision as 17 September³⁰, and a third gives 5 October. The Bank of England publishes the definitive schedule of MPC meeting dates on its website, and that is the place to check rather than relying on news reports. What is consistent across the sources is the shape of the year: eight meetings, decisions at midday on a Thursday, and a December meeting that is usually the last of the year⁵.

Inflation, the base rate and what your savings are really earning

The base rate only tells half the story of what your savings are earning. The other half is inflation. If inflation is higher than the interest rate you earn, the spending power of your savings may still decrease, even though the balance is growing³¹. MoneyHelper makes the same point about fixed-rate bonds: your original investment will not hold its value in real terms, its buying power, if the interest you are getting is less than the rate of inflation over the investment period¹⁹.

The relationship works like this. The MPC raises the base rate to bring inflation down¹⁰, and its aim is to keep inflation as close as possible to 2%². Higher rates tend to mean higher savings rates, so a saver's nominal return usually improves when the Bank is fighting inflation. But the real return, what your money can buy, depends on the gap between your rate and inflation. In its November 2025 reporting, the Bank judged inflation to have peaked and projected it to slow to 3.2% by March 2026³². As of 17 September 2026, 76% of savings accounts offered a rate higher than inflation⁷, which means roughly a quarter did not: those accounts were losing spending power even while paying interest.

Tax takes a further slice, and it is about to take a bigger one. From 6 April 2027, the government will increase the savings basic rate to 22%, the savings higher rate to 42% and the savings additional rate to 47%³³. In practice, a basic-rate taxpayer will face a 22% charge on savings interest, higher-rate taxpayers 42%, and those in the additional rate 47%³⁴. The starting rate for savings is currently 0%²⁷, and the personal savings allowance and ISA rules determine how much of your interest is taxed at all. Our guides to how tax on savings interest works, the personal savings allowance and Cash ISAs cover this in detail.

The practical point is that the headline base rate is only the starting point for working out what you are really earning. A savings rate above the base rate can still be below inflation, and an above-inflation rate can still be cut back by tax. Checking all three, the account rate, inflation and your tax position, is what tells you whether your savings are actually growing in real terms.

Base rate changes and Cash ISAs

Cash ISA rates respond to the base rate in exactly the same indirect way as ordinary savings rates: the base rate influences the savings market, providers set their Cash ISA rates with reference to that market, and no Cash ISA is contractually required to follow the base rate. NS&I's Direct ISA is a typical example: the rate is variable, so NS&I can change it 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 change³⁵.

What makes a Cash ISA different is not how its rate moves but how the interest is taxed. Interest earned in a Cash ISA is free of income tax under the ISA rules, which is why Cash ISAs versus ordinary savings is a question about your tax position rather than about rates. That distinction is about to matter more, because the tax rates on savings interest outside an ISA are rising from April 2027³³.

One related change concerns stocks and shares ISAs rather than Cash ISAs. Recent legislation introduces a flat rate charge of 22% on any interest paid on cash held in a stocks and shares ISA and an innovative finance ISA, charged by the ISA manager to HMRC and representative of the savings basic rate³⁶. This does not affect a Cash ISA, where interest remains tax-free, but it is a reason to know which type of ISA you hold.

So when the base rate moves, expect Cash ISA rates to drift in the same direction as the wider market, with the same delays and the same variation between providers, but do not expect an automatic pass-through. The tax treatment inside the wrapper is fixed by law; the rate inside it is set by the provider.

Fixing before a cut: what changes and what does not

When cuts are forecast, many savers wonder whether to lock into a fixed-rate bond before rates fall. The mechanics are simple: a fixed rate is immune to base rate cuts during its term, so if the MPC cuts, a fixed bond taken out beforehand keeps paying the higher rate until maturity¹⁹. If the MPC holds or raises instead, the same bond keeps paying a rate that may then look uncompetitive, and your money stays locked in.

The forecast record argues for humility here. In early 2026 the base rate was forecast to be cut in March¹¹, yet by September 2026 the MPC had held the rate for the sixth month in a row⁷. Savers who fixed in anticipation of a spring cut spent those months locked in at rates that may not have beaten what was available on the open market. Forecasts from the OBR and from the Bank itself pointed to gradual reductions and stabilisation during 2026¹¹, but a gradual path still includes long pauses, which is exactly what happened.

What does not change when you fix is access. Fixed-rate bonds normally bar withdrawals during the term, so the money needs to be genuinely spare. When the term ends, the account matures and you choose a new home for the money at whatever rates then apply; our guide to what happens when a fixed-rate savings account matures covers that step. The comparison between easy access and fixed-rate savings sets out the trade-off in full: certainty and usually a higher rate, in exchange for access.

What savers can do when rates change

When the base rate moves, the savers who benefit are usually the ones who check their accounts rather than assume. The single most effective habit is to know what rate you are earning and what type of account it is, because the response to a base rate change depends entirely on that. A firm should tell you the current rate on your savings account on request, by phone or in branch¹⁷, and every account's summary box states whether the rate is variable or fixed.

If you hold a variable account, a base rate change is a prompt to compare. Providers are not obliged to pass on rises¹³, and after the February 2025 cut the average instant-access rate fell by only 0.13 percentage points²¹, so the gap between the best and worst accounts tends to widen at exactly these moments. Moving money between accounts is straightforward, and our guide to switching savings accounts explains the process. The different account types, from easy access to notice accounts and fixed-rate bonds, are compared in our guide to types of savings account.

If you hold a tracker, there is nothing to do: the rate follows the base rate under the account's terms⁶, with the timing and notice rules set out above. If you hold a fixed-rate bond, a base rate change changes nothing until maturity, though it is worth knowing what you will do when the term ends.

Two protections are worth remembering. First, notice rules: a provider must give advance notice of a rate cut on a variable account under its terms, and the Co-operative Bank's tracker terms, for example, require two months' personal notice before a decrease⁶. Second, deposit protection: whatever happens to rates, money in a UK-regulated savings account is protected up to the FSCS limit, which does not change with the base rate. Our guide to how FSCS protection works for savings covers that separately.

Finally, the base rate is only one piece of the wider economy, and its history shows how much it can move.
