Important information - the value of investments and the income from them can go down as well as up, so you may get back less than you invest.

The Bank of England kept interest rates on hold at 3.75% in July following an easing of inflation in June - but financial markets are predicting borrowing costs may soon be on the rise again.

The Monetary Policy Committee (MPC) voted 6-3 to keep rates on hold on Thursday. The decision was expected - headline Consumer Price Index (CPI) inflation has been edging lower and was confirmed as rising by 2.6% annually in June. That is ahead of the Bank’s 2% target but slightly below expectations. The Bank raises rates to combat higher inflation.

Inflation is expected to rise again, however, with renewed fighting in the Middle East pushing oil and future energy prices higher. 

Prices in the bond market reflect where investors believe rates are headed in the future. Prior to the latest rates decision, markets had been predicting the next movement in rates to be upwards, with a quarter-point rise most likely to arrive at the 5 November MPC meeting. A further rise is then possible next Spring. Any rise beyond that looks uncertain, according to current market levels.

That represents a slight softening of expectations - as many as three quarter-point rises were being predicted earlier this month.

The Bank must decide how much higher energy prices caused by the Middle East conflict are likely to become embedded. A spike in energy prices will push the headline level of inflation higher, but the Bank may not raise rates in response if it believes the rise is temporary - higher UK borrowing costs cannot bring down global energy prices.

The Bank will be wary, however, that higher energy prices can cause a wider inflationary spiral if they result into higher wages to meet those higher prices. This is what happened following Russia’s invasion of Ukraine.

Much depends, then, on the labour market - and here the backdrop is generally supportive of lower rates. Unemployment stuck at 4.9% in the three months to May, slightly ahead of the same period as before, while wage growth slowed in the same period to 3.4% for regular earnings (excluding bonuses) and 4.3% for total earnings (including bonuses). This extra ‘slack’ in the labour market makes it arguably less likely that high energy prices will translate into higher ingrained inflation.

Elsewhere in the world, the US Federal Reserve kept rates on hold at its latest rate-setting meeting, held a day before the Bank of England’s decision.

The next UK interest rate decision is scheduled for 17 September 2026 followed by MPC meetings on:

  • 5 November 2026
  • 17 December 2026
  • 4 February 2027

How rates have changed

The path ahead for interest rates, as implied by market prices, has changed significantly following the outbreak of the conflict in the Middle East. 

The chart below shows the implied level of interest rates from 16 February 2026, just before the conflict broke out, then more recent readings on 22 July and 28 July 2026. This is based on market prices for government bonds with different lengths of maturity.

You can see how the path for rates on 16 February - prior to the outbreak of fighting - was downwards. Expectations rose significantly after fighting broke out. The reading for 22 July shows that expectations rose to price in as many as three quarter-point rate rises over the year. Those expectations have moderated slightly over the past week and the most likely course - based on 28 July market prices - is for just two more rises.

As such, rates are expected to peak at 4.25% next year, although a further rise is possible. Please note that these prices are indicative and will change daily.

Where next for mortgage rates?

As a general rule, if the Bank of England moves interest rates then mortgage rates tend to follow. Ultimately, however, it is up to lenders to decide the rates they offer and changes to mortgage deals can often run ahead or behind changes in the Bank rate.

Mortgage rates jumped in line with the rising expectations for rates in the coming year. As recently as 3 March 2026, the best rate on a five-year fixed rate mortgage was 3.75% but this has now climbed to 4.38%1. Reports from the mortgage market suggest that many of the best deals have been pulled from sale.

Where next for savings rates?

Savings rates have climbed in line with the rise in interest rate expectations, although rates are ultimately set by account providers based largely on competition in the savings market.

The best rate currently available for Cash ISA accounts is 4.51%2 although this includes a time-limited boost to the rate which falls away after a year.

Cash options - the best ways to save

There are a number of potential homes for money if you decide to hold it in cash.

It makes sense to shield your cash returns from tax if you can, which means using part of your £20,000 annual ISA allowance to hold cash. Cash ISAs do this job - although any allowance you use for cash cannot then be used for investments.

Non-ISA cash accounts also exist but returns are potentially subject to tax at your rate of income tax, subject to certain allowances.

For this reason, some savers choose Premium Bonds, where there is no guaranteed rate of interest but monthly prizes are paid instead. Prizes are tax-free but the rates of return on Premium Bonds have also been falling. Moreover, you have to have above average luck in order to get those rates.

An increasingly popular cash option is to move cash savings to an investment account but utilise assets which produce a cash-like return while rates remain somewhat attractive. That would allow you to take advantage of above-inflation returns from cash while it lasts, but also leave you ready to switch to investments if and when that suits you.

Cash funds or money market funds held inside investment accounts can do this job. The Fidelity Cash Fund is the best-selling cash fund on the Fidelity Investing platform.
