Why savings rates are moving now
Some of the UK’s leading savings rates have been rising again, even though the Bank of England has kept Bank Rate at 3.75%. Fixed savings rates have been particularly active, while competition has also pushed some Cash ISA rates higher.
At first, that can seem contradictory. If Bank Rate has not gone up, why would a bank or building society suddenly pay more interest to savers?
The reason is that Bank Rate influences savings rates, but it does not set them. Banks and building societies decide what interest rates to offer, taking into account competition, their own funding needs and conditions in financial markets as well as the current Bank Rate.
Savings rates are moving even though Bank Rate is still 3.75%
The Bank of England kept Bank Rate at 3.75% at its September meeting. Six members of the Monetary Policy Committee voted to leave it unchanged, while three preferred an immediate increase to 4%.
At the same time, the savings market has been moving. Moneyfacts reported on 24 September that most leading fixed savings rates had risen again as providers increased rates across their ranges. By 25 September, leading fixed-rate bonds were paying more than 5% across several terms, while the highest five-year fixed rate listed by Moneyfacts had reached 5.33% AER.
Cash ISAs have also been affected. On 22 September, Moneyfacts reported increased competition across easy-access and fixed Cash ISAs, with leading fixed Cash ISA rates of 4.82% for one year, 4.98% for two years and 5.25% for five years.
That does not mean savings rates everywhere have suddenly increased. Easy-access rates have behaved differently from fixed rates, and individual providers continue to offer very different returns. What has changed most clearly is the pricing towards the competitive end of the fixed savings market.
Bank Rate influences savings rates, but it doesn’t set them
Bank Rate is the interest rate set by the Bank of England. It influences interest rates throughout the economy, including the rates available on mortgages, loans and savings accounts.
But a Bank Rate of 3.75% does not mean a savings account has to pay 3.75%. A bank or building society can offer more or less than this depending on how it wants to price a particular account.
This is why savings rates do not necessarily move at the same time, or by the same amount, as Bank Rate. Our analysis of why savings rates did not rise as quickly as Bank Rate during the previous rate cycle shows how the relationship between the two can change over time.
The same principle also works in the other direction. Savings providers do not have to wait for the Bank of England to increase Bank Rate before deciding to offer a higher rate.
Why are some savings providers raising rates now?
There is rarely one explanation for a change in savings rates across the market. Several factors can influence how providers price their accounts.
Why savings rates can rise without a Bank Rate increase
Interest rate expectations
Savings providers operate in financial markets that are continually adjusting to expectations about future interest rates. Those expectations can change even while Bank Rate itself remains unchanged.
Competition for savings
Banks and building societies compete for deposits. If one provider increases a rate to attract savers, others may respond with higher rates or new accounts of their own.
Provider funding needs
Customer deposits are a source of funding for banks and building societies. A provider that wants to attract more deposits may decide it is worthwhile offering a more competitive savings rate.
Wider market rates
The cost and value of money over future periods are reflected in financial-market interest rates. These can move before the Bank of England changes Bank Rate.
Current conditions show why expectations can matter. UK CPI inflation rose from 2.9% in July to 3.1% in August, according to the Office for National Statistics. Inflation therefore remains above the Bank of England’s 2% target.
The September Bank Rate decision also showed that views within the Monetary Policy Committee are not unanimous. Three of its nine members wanted to increase Bank Rate from 3.75% to 4% immediately.
Financial markets have also changed. In the minutes of its September meeting, the Bank of England said short-term market interest rates had risen and that the perceived probability of a near-term increase in Bank Rate had increased.
None of this means that Bank Rate is certain to rise. The Bank of England’s September Market Participants Survey actually showed a median expectation for Bank Rate to remain at 3.75% at both the November and December meetings. Expectations can change as new economic information becomes available.
The important point for savers is that savings providers do not operate only on the basis of today’s Bank Rate. The wider interest-rate environment can start changing before the Monetary Policy Committee makes another decision.
Why can fixed savings rates move before Bank Rate?
This relationship is particularly important for fixed-rate savings accounts.
With an easy-access account, the interest rate is normally variable, which means the provider can change it in the future. A fixed-rate account works differently. The provider agrees to pay a particular rate for a specified period, such as one, two or five years.
That means a provider offering a fixed account today has to think beyond today’s Bank Rate. It is making a commitment about what it will pay savers over the months or years ahead.
Expectations about future interest rates and wider financial-market conditions can therefore influence the rate a provider is prepared to offer. If those expectations change, fixed savings rates can move even though the Monetary Policy Committee has not changed Bank Rate.
This also helps explain why different fixed terms do not necessarily pay progressively higher rates. Our guide to easy-access vs fixed-rate savings explains the wider differences between keeping money accessible and fixing an interest rate for a defined period.
Does this mean all savings rates are going up?
No. Headlines about rising savings rates usually refer to particular parts of the market or the most competitive accounts available at that point in time.
Moneyfacts data illustrates the difference. Its September savings trends report showed that the average one-year fixed savings rate had increased for six consecutive months, reaching 4.28% at the beginning of September. Average longer-term fixed rates had also increased. In contrast, the average easy-access savings rate remained at 2.53% for a third consecutive month, while the average easy-access Cash ISA rate fell to 2.71%.
This creates an important distinction between what is happening to the most competitive rates in the market and what an individual saver is actually earning.
Someone who has held the same savings account for several years may therefore see headlines about rates above 5% while the rate on their own account remains considerably lower. Our guide to switching savings accounts for a better rate explains what to consider when comparing an existing account with other options.
Why are Cash ISA rates rising too?
Cash ISAs are part of the same competitive savings market. The ISA wrapper changes the tax treatment of the interest, but banks and building societies still decide what rate to offer on their Cash ISA accounts.
Competition has recently been particularly visible in fixed Cash ISAs. Moneyfacts reported on 22 September that leading rates had increased across several fixed terms, including 4.82% AER for one year, 4.98% for two years and 5.25% for five years.
The tax treatment does not mean a Cash ISA will necessarily pay more than an ordinary savings account. Rates can differ between providers, account types and terms, and those differences can change over time.
If you are unfamiliar with the tax wrapper itself, our guide to what a Cash ISA is explains how these accounts work and how the ISA allowance applies.
Will savings rates keep rising?
It is not possible to know from the recent increases alone whether savings rates will continue rising.
Future pricing will depend partly on what happens to inflation and expectations for Bank Rate, but competition and individual providers’ funding requirements will continue to matter as well.
The Bank of England’s next scheduled Bank Rate decision is on 5 November 2026. However, savings rates can change before then. Providers can launch, withdraw or reprice accounts whenever their commercial and funding decisions change.
This means the next Bank Rate announcement is important, but it is not the only event capable of changing the savings market.
What should savers look at besides the headline interest rate?
Higher headline rates can attract attention, but the interest rate is only one part of a savings account.
An easy-access account may include a temporary bonus or restrictions on the number of withdrawals. A notice account may require advance warning before money can be taken out, while a fixed-rate account may restrict access or impose an interest penalty for withdrawing money early.
Minimum deposits, maximum balances and the way interest is paid can also vary. A high advertised rate may therefore apply to an account that works very differently from another account offering a slightly lower rate.
Our guide to comparing savings accounts explains how these features can be considered alongside the headline interest rate.
Conclusion
There is no contradiction between Bank Rate remaining at 3.75% and some savings rates rising.
Bank Rate is an important influence on the savings market, but banks and building societies set their own account rates. Expectations about future interest rates, movements in financial markets, competition for deposits and individual providers’ funding needs can all affect what they are prepared to pay savers.
The recent increase in fixed savings and Cash ISA rates is a useful example of that relationship in practice. Savings rates can begin moving before the Bank of England changes Bank Rate itself — and different parts of the savings market can move in different directions at the same time.

Methodology
This article uses current Bank of England monetary policy information, Office for National Statistics inflation data and current UK savings market data to explain why savings rates can change even when Bank Rate remains unchanged. Bank of England evidence is used to establish the current Bank Rate, the September 2026 Monetary Policy Committee decision and changes in market interest-rate expectations. ONS data is used for the latest UK inflation position. Moneyfacts market data is used to illustrate recent movements in leading fixed savings and Cash ISA rates. The article explains established factors that can influence savings pricing, including competition for deposits, provider funding requirements and wider market interest rates, rather than attempting to predict future savings rates or Bank Rate.
Limitations
Savings rates and individual products can change at short notice, so rates mentioned in this article describe the market at the stated dates and may subsequently change. Leading rates do not represent the rates available to every saver or show that the whole savings market is moving in the same direction. Several factors can influence how banks and building societies price savings accounts, and a change in a particular provider’s rate should not automatically be attributed to one factor unless the provider has stated its reason. This article does not predict future savings rates, Cash ISA rates or Bank Rate. Market conditions described are the current position as at 26 September 2026.
