As the war in the Middle East continues, financial instability escalates at home, here in Britain. Headlines change daily, leading to a volatile mortgage market where lenders adjust products quickly. Consequently, for many homeowners and buyers, it can feel overwhelming. It is easy to feel unsure about the right next step.

At Harbour Mortgage Solutions, our role is to bring clarity, calm, and confidence to your financial decisions, especially in a volatile mortgage market. Unpredictability doesn’t have to lead to confusion. With the right guidance, you can stay firmly in control of your plans.

This article aims to answer many of the common questions we are hearing right now. Similarly, we want to give you the confidence to talk to us so you can navigate the changes with our expert help.

Why Are Mortgage Rates Moving So Much Right Now?

A volatile mortgage market is driven by several key factors, including:

1. Changes in inflation:

Inflation is the root driver of almost everything; that’s why there is always so much anticipation when inflation changes are announced.

How it works:

• Higher inflation means markets expect higher interest rates in the future.
• That pushes up swap rates (what lenders use to price fixed mortgages – learn more about swap rates here).
• The result: mortgage rates rise, even before any official rate change.

What’s happening to mortgages right now?

According to the House of Commons Library (as of 24th March 2026), previously anticipated interest rate cuts, which we highlighted at the beginning of the year in our blog ‘Mortgages in 2026‘, seem unlikely to materialise. Sadly, the conflict in the Middle East, leading to higher fuel and energy prices, is now likely to cause inflation to rise.

Consequently, markets are shifting from expecting rate cuts to anticipating possible hikes. The key point here is that inflation doesn’t just affect mortgages directly; it changes expectations, which move markets faster than policy.

2. Bank of England base rate decisions

The Bank of England base rate provides the anchor for the whole system. However, they do not form the whole story in a volatile mortgage market.

How it works:

The base rate sets borrowing costs for banks. This directly influences tracker and variable-rate mortgages immediately. Likewise, it also signals the Bank’s view on inflation, which can lead to anticipation and uncertainty, creating a volatile mortgage market.

What does this mean for borrowers?

Those on a tracker or variable-rate mortgage will see an immediate increase in their mortgage prices. However, fixed-rate mortgages are not directly priced off the Bank of England base rate. These are based on expected future rates (swap markets). That’s why mortgage rates can rise even when the base rate is unchanged, or fall before the Bank cuts rates.

This is what we have seen happening over the last couple of months. Initially, at the beginning of the year, mortgage lenders anticipated a cut in the base rate, so they began offering competitive, lower fixed-rate mortgage products. The war in the Middle East and its economic impact on the world are now causing lenders to predict a rise in the base rate. Consequently, they are re-evaluating the products they are offering.

3. Lender funding costs

This is the most important short-term driver right now.

How it works:

Lenders fund mortgages via customer deposits and wholesale markets (linked to the swap rate). As the funding costs rise, lenders must increase mortgage rates to maintain their margins.

What drives funding costs?

• Market interest rate expectations
• Inflation outlook
• Government bond yields
• Global financial stress

Unfortunately, swap rates and wholesale funding costs have surged due to inflation fears and global instability. This has contributed to a volatile mortgage market, with rapid repricing and the withdrawal of hundreds of mortgage deals. Therefore, in many respects, funding costs are the true pricing engine. Even with a stable base rate, rising funding costs lead to higher mortgage rates.

4. Shifts in risk appetite across the market

This is the final contributor to a volatile mortgage market, the human behaviour layer, on top of the maths. Risk appetite refers to how willing lenders are to offer cheap deals, lend to higher-risk borrowers, and compete aggressively.

How it works:

When risk appetite is low, lenders increase rates to price in risk. Likewise, they tighten their criteria by requesting bigger deposits and stricter checks. Finally, they pull deals quickly. However, when risk appetite is high, competition increases, which leads to lower rates.

What’s happening in mortgage markets now?

Certainly, lenders are more cautious due to the levels of uncertainty around inflation and world politics. Currently, mortgage providers are repricing and withdrawing their deals. Certainly, they do not want to be ‘too cheap’ and get flooded with demand, or be left exposed if conditions worsen.

The Big Picture – A Volatile Mortgage Market

At this moment in time, all four of these elements are moving at once:

• Inflation outlook → unstable (energy shocks)
• Base rate expectations → flipped from cuts to hikes
• Funding costs → rising quickly
• Risk appetite → falling

That combination leads to a volatile mortgage market because:

• There is rapid repricing (sometimes within days)
• Deals are being pulled suddenly
• Mortgage rates are rising even without policy changes – the base rate remains at 3.75%, for example, but mortgage rates are getting higher.

What Does This Mean For Homeowners?

If you’re approaching the end of your fixed rate or considering raising capital, now is the time to review your options early.
Product Transfers
Many lenders allow you to secure a new rate months in advance, giving you protection if rates rise and flexibility if they fall.
Remortgaging
If you’re exploring a new lender, we can assess affordability, criteria, and costs to ensure the solution aligns with your long‑term goals.
Early Repayment Charges
We’ll help you to understand whether switching early is beneficial or if waiting is the more cost‑effective route to take.

The key message is don’t leave it until the last minute. Early planning gives you more control.

What Does A Volatile Mortgage Market Mean for First-Time Buyers?

Volatility can feel intimidating, but it doesn’t have to derail your plans.

We’ll help you to focus on what you can control:

• Building your deposit
• Strengthening your credit profile
• Reducing unsecured debt
• Preparing documents early

At present, affordability is changing. What’s possible today may look very different next month. Therefore, personalised advice is more important than ever. The good news? Opportunities do still exist! Even in a volatile mortgage market, competitive products remain available, and we can help you navigate them with confidence.

Why Mortgage Headline Rates Can Be Misleading

Naturally, when we experience a volatile mortgage market, it is tempting to focus on the lowest rate advertised, but suitability is far more important than the headline number. A mortgage should be assessed on:

• Fees
• Flexibility
• Overpayment options
• Term length
• Long-term affordability
• Your personal goals
