Mortgage Rates Are Rising Again: What Borrowers Should Know

The 10-Second Takeaway

After a relatively calm start to 2026, the mortgage market has been hit by a sudden volatility spike.

Rising energy prices linked to Middle East tensions have pushed swap rates higher, which lenders use to price fixed mortgages. As a result, mortgage rates have moved back above 5%, and lenders have started withdrawing products from the market.

Hundreds of deals have been pulled or repriced in recent days, and the window for sub-4% deals appears to be closing quickly.

If your mortgage deal ends within the next six months, securing a rate now could act as an insurance policy against further increases while still allowing flexibility if rates fall later.

After several months of gradually improving mortgage pricing, the UK mortgage market has experienced a sharp reversal on 11 March 2026.

Average mortgage rates have climbed back above the 5% threshold, and lenders are withdrawing products while financial markets react to global developments.

The key driver behind this sudden shift is the movement in swap rates.

Swap rates are the financial instruments lenders use to price fixed-rate mortgages. When expectations around inflation or interest rates change, swap rates can move quickly, forcing lenders to adjust their mortgage pricing.

Recent geopolitical tensions in the Middle East have pushed energy prices higher, raising concerns that inflation may remain elevated for longer than previously expected. This has caused swap rates to rise sharply and mortgage pricing to follow.

Mortgage Rates Cross the 5% Mark Again

Current UK mortgage averages now look like this:

Only a week ago, average two-year deals were closer to 4.84%, highlighting how quickly the market can change.

Lenders Are Withdrawing Mortgage Deals

Another clear sign of market volatility is the number of products being withdrawn by lenders.

Several major lenders have recently removed deals while repricing them, including:

• HSBC
• Barclays
• Nationwide
• NatWest
• Santander

Industry estimates suggest around 50 to 60 mortgage products were withdrawn in a short period, with many returning later at higher rates.

Lenders such as HSBC and Santander often lead the market in pricing. When they withdraw deals, it is often seen as a “canary in the coal mine” for the wider mortgage industry, signalling that other lenders may soon follow with similar repricing.

A similar pattern occurred during the early stages of the Ukraine conflict, when lenders withdrew products before relaunching them at higher pricing.

The Shift in Interest Rate Expectations

Mortgage markets are also reacting to changing expectations around central bank policy.

At the start of 2026, many analysts expected the Bank of England to begin cutting interest rates early this year.

However, market sentiment has shifted.

Recent forecasts suggest:

• The probability of a March rate cut has dropped from around 80% to roughly 20%
• Many economists now expect the Bank of England to hold the base rate at 3.75%
• Some analysts believe rate cuts may not happen at all during 2026

While forecasts can change quickly, these expectations have already influenced mortgage pricing.

A Double Shock for Many Homeowners

Many borrowers approaching remortgage are already facing a significant increase in monthly payments.

During the pandemic, many homeowners secured mortgage rates close to 1% or 2%.

As those deals expire, borrowers are moving onto rates closer to 5%, which can significantly increase monthly repayments.

In fact, many borrowers are experiencing what we described in a previous article as the double shock when remortgaging in 2026, where homeowners leaving ultra-low pandemic mortgage deals suddenly face much higher repayments.

If mortgage rates continue to rise, this gap could become even larger for borrowers who delay securing a new deal.

Why Many Borrowers Secure a Rate Six Months Early

One advantage of the UK mortgage system is that borrowers can often apply for a new mortgage up to six months before their current deal ends.

Most mortgage offers remain valid for three to six months, depending on the lender.

This allows borrowers to secure a rate today and still complete their remortgage when their current deal expires.

This strategy offers two key benefits.

• If rates rise further, the borrower keeps the lower rate secured earlier.
• If rates fall later, borrowers can often switch to a cheaper product before completion.

Why Waiting Can Be Risky

Mortgage products can disappear very quickly during volatile markets.

A deal available today may not be available tomorrow if lenders withdraw or reprice their products.

Importantly, the mortgage rate is usually only secured once a full application has been submitted.

Simply receiving an illustration or quote does not guarantee the rate will still be available later.

Two-Year vs Five-Year Fix: Which Is Better?

Borrowers often ask whether a two-year or five-year fixed rate is better.

The answer depends on individual circumstances.

Some borrowers prefer two-year deals to retain flexibility if interest rates fall in the near future.

Others choose five-year deals for longer-term payment stability.

Buyers Should Also Be Aware

This volatility also affects people currently buying property.

If buyers delay their mortgage application while waiting for rates to fall, there is a risk that current deals may disappear or return at higher pricing.

During uncertain markets, acting sooner may help secure a mortgage rate before further changes occur.

Check Your Mortgage Options Early

Is your mortgage deal ending within the next six months?

Securing a rate early may help protect you against further increases while still giving you flexibility if rates fall later.

You may wish to speak to a qualified mortgage adviser who can review your options and help secure a suitable deal for your circumstances.
