Mortgage Rates Begin Falling Despite Ongoing Iran War

After weeks of mortgage rate increases driven by the Iran conflict, there are now early signs that UK lenders may begin easing pricing at the margins. While this does not yet point to a sustained mortgage rate fall, it does suggest that the sharp upward pressure seen in recent weeks could be starting to stabilise.

However, property investors are still not breathing easy because they are not sure whether this marks the beginning of a gradual easing in borrowing costs or if this is simply a temporary pause with more hikes yet to come.

This article explores what is currently driving mortgage pricing, how geopolitical developments continue to influence lender behaviour, and what investors should be focusing on while conditions remain uncertain.

Iran War is Not Over. So, Why Are Mortgage Rates Falling?

When it began, the Iran war unsettled financial markets due to its impact on global energy supply. Disruptions to oil routes caused a rise in energy prices, which then fed directly into broader inflation forecasts.

When inflation expectations rise, financial markets adjust quickly. One of the key channels for this is the swaps market, which lenders rely on to price fixed-rate mortgages. Swap rates effectively represent the market’s forecast of future interest rates, and they respond almost immediately to changes in inflation and economic risk sentiment.

But as tensions seem to have eased in the past week and maritime traffic through the vital Strait of Hormuz appears to be returning to relative normalcy, the aforementioned inflation fears have softened. In response, swap rates have edged lower. This shift has allowed major lenders such as Halifax, HSBC, and Santander to reduce pricing on selected mortgage products.

On the surface, this appears to be a straightforward improvement for property investors. Lower swap rates generally translate into cheaper fixed-rate deals, which is why headline mortgage rates have begun to drift down.

However, the underlying picture is still uncertain. These improvements are not being driven by stronger UK economic fundamentals or sustained disinflation. Instead, they are largely the result of rapidly changing geopolitical sentiment. If global tensions flare again, or if energy markets tighten, swap rates could just as quickly reverse.

How Much Have Mortgage Rates Fallen?

Average UK two-year fixed mortgage rates have only seen a very marginal improvement.

At the height of the recent market disruption linked to the Iran war, average rates rose from around 4.83% to a peak of approximately 5.90%. Since then, they have eased slightly to about 5.87%.

In practical terms, this is not a meaningful reduction in borrowing costs. For most borrowers, the monthly repayment impact is almost negligible. Instead, what this movement reflects is a shift in market sentiment rather than a structural change in lending conditions. Property investors and lenders are essentially adjusting their expectations that the worst-case inflation scenario may not materialise.

However, it is important to be clear that this is not a confirmed downward trend in interest rates. If inflation expectations rise again or geopolitical risks re-escalate, borrowing costs could move higher just as quickly as they have recently eased.

Is the Pressure on UK Property Investors Only Coming From Mortgage Rates?

Mortgage rates tend to dominate property headlines, but they are only one part of a much wider financial environment shaping investment performance in the UK.

According to the Office for National Statistics, around 67% of UK adults reported that their cost of living had increased in March, with essentials such as food and fuel continuing to squeeze families. While this is often discussed as a household issue, it also feeds directly into the property market through affordability constraints and shifting demand dynamics.

For property investors, the key implication is not just higher borrowing costs, but the broader squeeze on disposable income across the economy. Even when demand for housing remains structurally strong, affordability limits how far those looking to buy or rent those houses can realistically move without resistance.

What Should Property Investors Do in the Present Market?

Property investors should not try to predict short-term movements in UK mortgage rates. Instead, they should focus on what can be controlled within an increasingly uncertain lending environment.

Rather than waiting for marginal improvements in pricing, they should prioritise deals that remain viable under current borrowing conditions. This means assessing investments based on today’s mortgage rates, not assuming that cheaper debt will materialise in the future.

A key part of this approach is stricter financial stress testing. Instead of modelling purchases against optimistic rate reductions, investors should run scenarios based on higher-for-longer borrowing costs to ensure cash flow remains stable even if refinancing becomes more expensive.

Alongside this, they should emphasise liquidity and financial buffers. Investors should recognise that volatility in interest rates, swap rates, and lender pricing is no longer a temporary phase, but a structural feature of the current market cycle.

Is There an Opportunity for Property Investors in a High-Interest Market?

Periods of uncertainty in the UK mortgage market tend to separate reactive buyers from more strategic property investors.

Although borrowing costs remain significantly higher than the ultra-low interest rate era, and overall market uncertainty is still elevated, these conditions are also creating selective opportunities for well-prepared investors.

When less experienced buyers step back due to volatility in mortgage rates and broader economic concerns, competition in certain segments of the property market typically reduces. This can result in more motivated sellers, greater scope for negotiation, and improved conditions for structuring deals.

In this environment, pricing flexibility also increases, not because fundamentals have improved, but because buyer demand becomes more cautious. That shift can allow experienced investors to secure assets on more favourable terms than would be possible in a highly competitive market. Then, there is also the fact that the UK property sector has always proven reliable in times of global upheavals.

However, these opportunities are only valuable if the underlying investment remains viable under realistic financial conditions. Deals that rely on optimistic assumptions about falling interest rates or improving affordability are significantly more exposed to risk.

Conclusion

Recent easing in UK mortgage rates should not be viewed as the start of a sustained fall, because it may not be. For property investors, the key point is that uncertainty remains embedded in the market. Rates can move quickly in either direction, meaning financing conditions are far from settled.

In this environment, success is not about timing the next move in interest rates, but about building strategies that remain viable regardless of fluctuations.
