Fixed rates have risen twice since September as markets price a November rate rise. Islay Robinson on why product speed now matters more than the rate.

Why Mortgage Rates Are Rising Even Though The Base Rate Has Not

The Bank of England held Bank Rate at 3.75% on 17 September. Since then, the UK's largest mortgage lenders have raised their fixed rates again, with lenders including HSBC, Barclays, NatWest, Santander and Lloyds among those repricing. Nothing about the base rate has changed. What has changed is what the market expects to happen next.

As of 22 September, interest rate futures put the odds of a quarter-point rise at the 5 November meeting at around 67%, against 33% for another hold. Days before the September decision, that split was close to the reverse. The market was also pricing the first rise by December. For borrowers with a mortgage deal ending in the next year, that shift matters because mortgage pricing follows market expectations as well as actual Bank Rate decisions.

How Far Fixed Rates Have Moved Since March

According to Moneyfacts data, the average five-year fixed mortgage rate has risen to 5.91%, up from 4.94% in early March. The average two-year fixed rate has also risen significantly from its spring level and was approaching 5.9% by late September.

The move has been substantial. In March, Moneyfacts recorded an average two-year fixed rate of 4.84% and a five-year fixed rate of 4.96%. By April, those averages had risen to 5.84% and 5.75% respectively as lenders responded to sharp movements in swap rates and inflation expectations.

These are market averages rather than the rates any individual borrower will be offered. The rate available to a particular borrower will depend on factors including loan size, loan-to-value, income, property and lender criteria. The direction of travel, however, has been clear since the spring.

The market has also experienced significant product churn. Moneyfacts recorded a record-low average mortgage product shelf life of eight days in April, after lenders withdrew 1,283 products in March as uncertainty over the future path of interest rates increased.

Islay's View: Where The Opportunity Sits

In my view, the headline figures are less important than what is happening beneath them. Prime London is not moving as one market, and buyers need to distinguish between properties where sellers are genuinely willing to negotiate and those where demand remains strong.

What I am seeing is a greater emphasis on certainty. Buyers who have their financing arranged before they find the property can move quickly when the right opportunity appears. At this level of the market, that can be just as important as the price being offered.

Why Lenders Are Repricing Before The Bank Acts

Fixed mortgage rates are influenced heavily by swap rates, which reflect market expectations for interest rates over the life of a mortgage. When expectations of higher rates become more firmly established, swap rates can rise and lenders may reprice their fixed products before the Monetary Policy Committee announces a change in Bank Rate.

The latest repricing has followed a renewed increase in inflation concerns and energy prices. The Bank of England said in September that crude and refined energy prices had risen further and remained volatile as a result of the conflict in the Middle East.

UK CPI inflation had already reached 3.1% in August, above the Bank's 2% target. The Office for National Statistics confirmed that CPI increased by 3.1% in the 12 months to August 2026, up from 2.9% in July.

The September MPC meeting also showed a clear division over the appropriate response. Six members voted to maintain Bank Rate at 3.75%, while three voted for an immediate increase to 4%. The Bank said the risks to the inflation outlook had become more tilted towards the upside.

The Bank's July Monetary Policy Report had already modelled an adverse scenario in which CPI inflation reached 4.5% in the second quarter of 2027, largely as a result of substantially higher energy prices. That was a scenario rather than the Bank's central forecast.

What Has Changed In Client Conversations

A month ago, much of the discussion around fixed-rate mortgages centred on whether borrowers should secure a rate or wait for the possibility of lower pricing later in the year. With market pricing now reflecting a greater possibility of higher Bank Rate, that conversation has changed for some borrowers whose deals are due to expire soon.

That is a general market observation, not a recommendation for every borrower. The appropriate decision depends on individual circumstances, including when the current mortgage deal ends, any early repayment charges and how much certainty the borrower wants over future payments.

Rates can fall as well as rise, and market expectations can change quickly. If energy prices ease or inflationary pressures prove more temporary than currently expected, swap rates and mortgage pricing could move in the other direction.

The Number To Watch Is Product Shelf Life, Not Just The Headline Rate

The figure I pay most attention to is not simply the average mortgage rate. It is how quickly lenders are changing and withdrawing products.

The average mortgage product shelf life fell to just eight days in April, according to Moneyfacts, its shortest period since records began in 2011. It subsequently recovered, reaching 14 days in June and 11 days in July as product availability improved.

That matters because the practical risk for borrowers is not simply that a rate may be slightly higher next week. A product can disappear altogether as lenders adjust their ranges.

Recent market movements have demonstrated how quickly this can happen. The Financial Times reported in September that major lenders had raised fixed mortgage rates as swap rates increased, with some lenders repricing for a second time within a week.

For borrowers, particularly those seeking larger or more complex mortgages, identifying suitable lenders and preparing an application efficiently can therefore become important when products are changing rapidly.

Buy-To-Let Borrowers Face The Same Pressure

Landlords are facing the same changes in fixed-rate pricing, alongside the affordability and rental stress-testing requirements that apply to buy-to-let lending.

The Bank of England's updated buy-to-let underwriting standards set out requirements around affordability assessment, interest-rate stress testing and portfolio landlords. The updated supervisory statement takes effect from January 2027.

For landlords whose mortgage deals end before spring 2027, the same consideration applies as for residential borrowers: the Bank of England's next decision is only one part of the pricing picture. Lenders can change their fixed-rate products before or after an MPC meeting as swap rates, funding costs and market expectations change.

This Is Not 2022, But The Market Has Become More Volatile

None of this approaches the disruption seen after the 2022 mini-Budget, when a large number of mortgage products disappeared from the market in a matter of days.

The current adjustment has been more gradual, although lenders have continued to reprice as swap rates and inflation expectations have changed. Moneyfacts' data shows that product availability recovered significantly after the disruption in March and April, even as fixed-rate pricing subsequently began moving higher again.

The key difference for borrowers is that the Bank Rate decision itself is no longer the only event to watch. Fixed mortgage pricing can move ahead of an MPC decision because lenders are responding to changes in wholesale funding markets and expectations for future interest rates.

What Borrowers Should Watch Before November

The more useful question for borrowers is not simply what the Bank of England will do on 5 November. It is how much of the market's expectations for that decision are already reflected in the mortgage products available today.

The Bank of England's September Market Participants Survey shows that the median expectation among respondents remained for Bank Rate to be 3.75% following the November meeting, although the upper quartile was 3.81%. By December, the upper quartile had moved to 4%, highlighting the uncertainty around the path ahead.

That is an important distinction between market pricing and consensus expectations. SONIA futures provide a real-time indication of what is being priced by financial markets, while the Bank's survey captures the expectations of a group of market participants. Neither is a guarantee of what the MPC will ultimately do.

For borrowers approaching the end of a fixed-rate period, the practical issue is therefore less about predicting the next Bank Rate decision and more about understanding how current mortgage pricing fits with their own refinancing timetable.

For high-value borrowers, business owners, international clients and those with complex income structures, lender assessment may require more detailed documentation and can take longer than a straightforward residential mortgage application.

The market is moving before the Bank does. For borrowers with refinancing decisions ahead, understanding that distinction is likely to remain important as November approaches.
