Base rate increase: what does it mean for your mortgage and savings?

Bank of England agrees 12th successive base rate hike
Bank of England

The Bank of England has increased the base rate for the 12th time in a row, taking the figure to 4.5%.

Members of the Bank's Monetary Policy Committee (MPC) voted for a 0.25 percentage point rise as they try to lower stubbornly high inflation.

The rise - which has taken the base rate to its highest level since October 2008 - is unwelcome news for mortgage holders who are facing heightened interest rates in the midst of a cost-of-living crisis.

Here, Which? takes a look at what yet another increase could mean for homeowners and savers.

Bank of England raises base rate to 4.5% 

The MPC has voted by a majority of 7-2 to increase the base rate by 0.25 percentage points. 

The current rate base is a far cry from the historic lows of December 2021, when it stood at just 0.1%.

The graph below shows how the base rate has changed since July 2008, using data from the Bank of England.

Committee members set the base rate as part of the Bank's efforts to keep inflation at 2%. Inflation currently measures 10.1% - more than five times the target.

The Bank of England anticipates inflation will 'fall quickly' this year and its 2% target will be met in late 2024. As it stands, however, inflation has proved stubborn - lingering around the 10% mark since last summer.

The Bank admits it will take longer for inflation to fall due to food prices remaining elevated.

Why does the base rate matter?

When the Bank of England lends money to commercial banks, the amount of interest they must pay back is determined by the base rate.

A higher base rate means lenders are charged more, and these costs are usually passed on to customers in the form of interest rate rises. 

Theoretically, a higher base rate should mean mortgages get more expensive and savings accounts pay more interest on your money, but that isn't always the case.  

Will this be the last base rate increase?

The latest rise had been anticipated by experts for weeks, but what happens in the future is open for debate.

There is widespread belief that the base rate is near its peak and will begin to head in the opposite direction, but economists are split on when that will be. Some suggest the rate will fall next month, while others believe we could see yet more increases in the coming months.

Ellie Henderson, from Investec Economics, said: 'What is clear is that the days of successive interest rate hikes in this economic cycle are limited, but the exact endpoint is clouded with uncertainties.'

Results of the next meeting will be published on Thursday 22 June.

What does the base rate rise mean for my mortgage?

The majority of homeowners have a fixed-rate mortgage, which means the rate stays the same for a set period – usually two or five years. 

If you've got a fixed-rate deal, you won't be immediately affected by the base rate change and will instead continue to pay the same amount until the end of your fixed term. 

When you come to remortgage, however, you're highly likely to find that deals have become more expensive

With rates rising, it's important to remember to switch deals at the end of your fixed term. If you don't, you'll be moved on to your lender's standard variable rate (SVR), which is more expensive and leaves you vulnerable to further base rate rises.

The graph below shows the relationship between base rate changes and mortgage rates for two and five-year fixes, using data from Moneyfacts.

Tracker, discount and standard variable rate mortgages

Tracker mortgages follow the base rate plus a set margin – for example, the base rate plus 1%. If you're on this type of deal, your rate will go up by 0.25 percentage points straight away, so borrowers will face immediate increases in their bills.

Discount mortgages work slightly differently. They provide a discount on your lender's SVR – for example, the SVR minus 1%.

Repayments on discount mortgages won't go up automatically due to the base rate rise, but there's a good chance your lender will increase its SVR by some or all of the rise in the coming days or weeks.

Higher rates will also have an impact on renters, as buy-to-let landlords will likely pass on increased costs to their tenants. 

What does the base rate rise mean for savings?

In theory, the base rate rise should lead to better interest rates on savings accounts. However, there's no guarantee your provider will pass on the latest increase – at least not immediately. 

Savings rates have been on the rise recently, but even the best current rates are nowhere near matching inflation. 

If you're thinking of switching to get a better rate, now is a good time to shop around to see what deals are available and whether you can take advantage of increased competition in the market. 

Rachel Springall, finance expert at Moneyfacts, said: 'Challenger banks and building societies are currently paying some of the best returns, so it is always worth considering the more unfamiliar brands that have the same deposit protections in place as a big high street bank.'

'Banks must do more to encourage saving'

Banks have been urged to do more to encourage saving, yet some of the biggest names are still only offering around 0.7% interest on instant access Isa and savings accounts. 

This week, the Treasury Committee called on banks to increase their savings rates. 

Committee chair Harriett Baldwin MP said: 'The UK’s biggest banks are continuing to squeeze record profits from their loyal savers. In a high interest rate environment banks must do more to encourage saving.'
