Why Mortgage Rates Don’t Always Follow the Base Rate

It is a common assumption that mortgage rates move in line with the Bank of England base rate. While the base rate plays an important role, it is not the only factor influencing what borrowers are offered.

In reality, mortgage pricing is shaped by a range of moving parts, and understanding these can help explain why rates sometimes rise even when the base rate remains unchanged.

The role of the base rate

The base rate is set by the Bank of England and directly affects variable and tracker mortgages. When the base rate changes, these products typically move in the same direction.

However, fixed-rate mortgages, which are often the most popular choice, are not directly tied to the base rate. Instead, the base rate is one of the factors, along with other mechanisms, that impact mortgage interest rates.

What are swap rates?

Swap rates are one of the key drivers behind fixed mortgage pricing. These are influenced by financial markets and reflect expectations about future interest rates, inflation and wider economic conditions.

Lenders use swap rates to price fixed-rate deals, which means mortgage rates can change based on market sentiment rather than current base rate decisions.

This is why borrowers may see rates increase even when the base rate is held.

Market expectations matter

Mortgage pricing is forward-looking. If markets expect interest rates to rise in the future, swap rates can increase in advance, pushing mortgage rates higher.

Equally, if there is confidence that rates will fall, swap rates may decrease, leading to more competitive mortgage deals.

This dynamic can sometimes feel counterintuitive, particularly when headlines focus solely on base rate announcements.

Other factors influencing mortgage rates

Lenders also consider a range of additional factors when setting rates. These include funding costs, competition within the market and their appetite for lending.

During periods of uncertainty, lenders may price more cautiously, which can lead to higher rates or the withdrawal of certain products.

What this means for borrowers

For borrowers, this means that waiting for a base rate change does not always result in better mortgage deals. In some cases, rates may move ahead of any official decision.

Understanding that mortgage pricing is influenced by both current conditions and future expectations can help set more realistic expectations.

A broader perspective

Mortgage rates are shaped by more than a single headline figure. By looking at the wider picture, borrowers can better understand why rates move the way they do and make more informed decisions as a result.
