UK Mortgage Market Faces Turmoil as Iran Conflict Drives Interest Rates Up

The UK mortgage market has been thrown back into a state of turbulence not seen since the aftermath of the 2022 mini‑Budget, as lenders scramble to reprice deals in response to global instability triggered by the U.S. Israel war with Iran.

Average rates on two‑year fixed mortgages have now climbed above 5%, reaching their highest level since last August, according to data from Moneyfacts. Five‑year fixes have also risen, marking their most expensive point since mid‑2024.

Little or no warning

The sudden shift has caught borrowers off guard. Nearly 500 mortgage products have been withdrawn in just 48 hours, the steepest contraction in available deals since the Truss–Kwarteng fiscal shock.

Lenders are reacting to sharp movements in gilt yields, which have become increasingly volatile as markets reassess the likelihood of Bank of England rate cuts this year.

Before the conflict erupted, investors had broadly expected the Bank to begin easing borrowing costs. That optimism evaporated as oil prices surged, raising the prospect of renewed inflationary pressure.

With Brent crude still more than 20% higher than before the war and reaching over 40% increase at one stage, expectations of cheaper mortgages have been replaced by fears of a prolonged period of elevated rates.

Timing

For homeowners approaching the end of a fixed deal, the timing is particularly painful. The average two‑year fix has jumped from 4.84% to 5.01% in less than four days, while five‑year rates have risen from 4.96% to 5.09%.

First‑time buyers, already squeezed by high prices and stagnant supply, face a shrinking pool of products and rising monthly costs.

The wider cost‑of‑living picture is also darkening. Petrol and diesel prices continue to climb as Middle East supply disruptions ripple through global energy markets.

With inflation risks resurfacing, the path for mortgage rates now hinges on how the conflict evolves — and whether markets can regain their footing.

Fuel up, energy costs up and mortgage rates up – all in just a weekend – that didn’t take long.

UK mortgage rates fall in January 2024

Mortgage rates down

Mortgage lenders have started 2024 by cutting interest rates.

The UK’s biggest lender, the Halifax, has cut some interest rates by nearly a full 1%, with other lenders expected to follow suit. HSBC has announced it will also make cuts in January.

Halifax is reducing its rates, with interest on a two-year fixed deal being cut by up to 0.83%. HSBC is due to reduce rates on its two-year fixed rate for remortgages (for someone with at least 40% equity in their home) falling below 4.5% for the first time since early June last year.

UK house prices experience biggest yearly decline since 2009

UK House Prices Fall

The Nationwide Building Society says house prices are 5.3% lower compared to August last year, in the biggest annual decline since 2009.

Nationwide said the drop represented a fall of £14,600 on a typical home in the UK since house prices peaked in August 2022. It also said higher borrowing costs for buyers had led to a slowdown in activity in the housing market. Mortgage approvals are also about 20% below pre-Covid levels.

After 14 rate increases from the Bank of England – a two year fixed rate mortgage is now touching 6.7%

Since December 2021, the Bank of England (BoE) has raised interest rates 14 times in row in a bid to clamp down on rising inflation in the UK. The bank’s base rate now stands at 5.25%. This has led to lenders raising their mortgage rates, putting increased pressure on homebuyers.

The average two-year fixed mortgage rate on Friday was 6.7%, while the average five-year fix was 6.19%.

Average house prices in the UK peaked at £273,751 in August 2022 but fell to £259,153 last month.

U.S. mortgage rates are high! Could they reach 8%?

Interest rates

The latest U.S. mortgage rates are the highest they have been in decades.

The average 30-year fixed-rate mortgage rose to 7.23% in the week ending 25th August 2023, up from 7.09% the week before, according to latest bank reports from U.S. This is the highest level since June 2001, when it was 7.24%.

The rate on a 30-year fixed mortgage increased to 7.31% in the week ended 18th August 2023, according to Mortgage Bankers Association data. This is the highest level since late 2000.

The 30-year fixed mortgage rate averaged 7.16% with 0.68 points as of August 16, according to U.S. News. This is up from 7.09% with 0.7 points the previous week. The adjustable-rate mortgage increased to 7.6%.

Inflation driving interest rates up

The rise in mortgage rates is driven by indications of ongoing economic strength and inflation pressures, which have also pushed up Treasury yields and the Federal Reserve’s interest rate expectations.

Higher mortgage rates make home buying more expensive and reduce the affordability of homeownership. They also discourage existing homeowners from selling or refinancing their homes, which contributes to the low inventory of available homes for sale.

As a result, home sales have declined and home prices have soared in many markets. Will interest rates touch 8%?
