The UK mortgage market is experiencing significant changes as swap rates soar, leading to increased mortgage pricing across various lenders. This surge is largely attributed to geopolitical tensions, particularly the escalating conflict between the US and Iran, which has driven oil prices to $100 per barrel for the first time since May. As a result, borrowers are facing higher costs for their mortgages.

What are the latest changes in the mortgage market?

As of July 22, the two-year swap rate rose from 3.993% to 4.258%, while the five-year swap rate increased from 4.034% to 4.316%. These changes have led to various lenders adjusting their mortgage rates. Nationwide has raised rates on several products for existing borrowers, including a two-year fixed additional borrowing product at 60% loan to value (LTV), which increased from 4.37% to 4.6%. Additionally, the rate for a 75% LTV deal rose from 4.46% to 4.68%. The fee-free five-year fixed options also saw price hikes.

Which lenders are increasing their rates in the mortgage market?

Nationwide is not alone in its rate adjustments. HSBC has announced its second rate increase of the week, effective from July 27, while Accord has raised new business rates for fixed residential mortgages up to 90% LTV by 0.2%. Notably, TSB has lifted rates on its two-year fixed residential purchase and remortgage products by up to 0.2%, with new rates starting at 4.59% for a deal at 60% LTV. Virgin Money has also adjusted its product transfer rates, increasing residential pricing by as much as 0.23%.

What does this mean for borrowers and landlords?

The rising swap rates and subsequent mortgage pricing hikes mean that borrowers and landlords will face higher costs when securing new mortgages or refinancing existing ones. For example, Nationwide’s two-year fixed product at 60% LTV now costs 4.6% with a £999 fee, which could impact affordability for many. Landlords looking to invest in buy-to-let properties will also see increased rates, as all new business rates for buy-to-let (BTL) mortgages have risen by 0.1%. This trend suggests that prospective buyers and current homeowners should act swiftly if they are considering locking in a rate before further increases occur.

What should borrowers watch for next in the mortgage market?

Borrowers should stay alert to further changes in the mortgage market, particularly as lenders continue to respond to fluctuating swap rates. With geopolitical tensions affecting economic stability, it is important for borrowers to monitor their options closely. Those looking to switch or secure a mortgage should consider comparing rates actively to find the best deal available. For ongoing updates, check our mortgage rate comparison tool.
