UK mortgage market
Base Rate Holds at 3.75%, but Mortgage Rates Are Rising. What Is Happening?

The Bank of England has once again kept the Base Rate at 3.75%, marking the sixth consecutive hold.
It might therefore seem reasonable to expect mortgage rates to remain relatively stable too.
However, some lenders have recently been increasing their mortgage rates.
So why can mortgage rates rise when the Bank of England has not increased the Base Rate?
The answer lies in how lenders price their mortgages, what is happening to swap rates and what financial markets expect may happen next.
Bank of England keeps the Base Rate at 3.75%
The Monetary Policy Committee voted to maintain the Bank Rate at 3.75%.
However, the vote itself demonstrates that there are different views within the Committee.
The decision was made by six votes to three, with three MPC members preferring an increase to 4%.
One of the major considerations is inflation.
UK inflation has risen to 3.1%
UK CPI inflation increased to 3.1% in August, up from 2.9%.
Inflation matters to the mortgage market because it is one of the factors considered by the Bank of England when setting monetary policy.
Energy and fuel prices, alongside geopolitical uncertainty, have added further complexity.
However, this does not make another Base Rate increase automatic. The Bank of England has to consider broader economic conditions, while some current inflationary pressure originates from global factors that domestic interest rates cannot directly control.
For mortgage borrowers, there is another important point:
mortgage rates can move without a change in the Base Rate.
Base Rate and mortgage rates are not the same
This is one of the most important distinctions for borrowers to understand.
When the Bank of England holds the Base Rate, it can be tempting to assume lenders should keep their mortgage rates unchanged too.
Mortgage pricing does not work quite like that.
The Base Rate is important, but lenders also consider their funding costs, swap rates, expectations for future interest rates, risk and competition within the mortgage market.
As a result, mortgage pricing can react to expectations about the future before the Bank of England makes its next decision.
What are swap rates?
Swap rates are particularly relevant to the pricing of fixed-rate mortgages.
In simple terms, they help reflect the cost and market expectations associated with funding over a particular period.
If financial markets expect interest rates to remain higher for longer, swap rates may rise.
That can increase the cost associated with providing fixed-rate mortgage products.
A lender may therefore increase its mortgage rates even while the Bank of England Base Rate remains unchanged.
This is why “Bank of England holds interest rates” does not necessarily mean “mortgage rates stay the same.”

Why can mortgage products change so quickly?
The mortgage market can react quickly to new financial and economic information.
If swap rates, inflation expectations or funding costs change, lenders may reprice their products.
Sometimes this means increasing a rate. In other cases, an existing product may be withdrawn and replaced.
At the same time, lenders are competing for customers.
Different banks and building societies have different lending targets, which means they do not necessarily respond to market conditions in exactly the same way.
It is therefore possible to see some lenders increasing rates while others continue to offer competitive deals for particular types of borrowers.
Will mortgage rates continue to rise?
There is no certainty.
Markets will continue to watch inflation, energy prices, economic data, swap rates and future Bank of England decisions.
Each of these could influence mortgage pricing.
Trying to identify the perfect time to take a mortgage or remortgage purely by predicting future interest rates can therefore be difficult.
Rates can move in either direction.
Is your fixed-rate mortgage coming to an end?
If your current fixed mortgage deal ends within the next few months, you do not necessarily need to wait until the final weeks to explore your options.
Starting a mortgage review earlier can provide more time to compare what is available.
This may include looking at your existing lender's options, remortgaging to another lender, associated fees, different fixed-rate periods and how different products could affect your monthly repayments.
It means a decision can be based on actual available options rather than solely on predictions about future rates.
What if you are buying a property?
The same principle applies to First Time Buyers and home movers.
The mortgage rate matters, but it is only one part of the lending decision.
Income, deposit, existing commitments, credit history, mortgage term and property type can all affect the products and borrowing options available.
This is why an advertised headline mortgage rate does not necessarily represent the rate available to every borrower.
Base Rate at 3.75% – what should borrowers remember?
The Bank of England has kept the Base Rate unchanged, but that does not mean the mortgage market has stopped moving.
Mortgage rates can change independently of the latest MPC decision because lenders also respond to swap rates, funding costs and expectations about future economic conditions.
Rather than relying solely on predictions about the next interest-rate move, borrowers can look at what is available based on their individual circumstances.
