The UK mortgage market is experiencing a significant shift as swap rates surge, prompting lenders to raise mortgage pricing across various products. This increase is primarily driven by geopolitical tensions, specifically the escalating conflict between the US and Iran, which has led to rising oil prices and subsequently impacted swap rates. Borrowers and landlords should be aware of these changes, as they will affect mortgage affordability and options.

What are the current swap rate changes?

As of 22 July, the two-year swap rate increased to 4.258%, up from 3.993% last month. The five-year swap rate also saw a rise, climbing from 4.034% to 4.316%. These changes reflect the broader economic impact of geopolitical events, particularly the conflict in the Middle East and rising oil prices, which have reached $100 per barrel for the first time since May.

How are lenders responding in the mortgage market?

In response to the rising swap rates, several major lenders have adjusted their mortgage pricing. Nationwide has increased rates for existing borrowers, with the two-year fixed additional borrowing product at 60% loan to value (LTV) rising from 4.37% to 4.6%. Similarly, the deal at 75% LTV has increased from 4.46% to 4.68%. Other lenders, including HSBC and Accord, have also raised their rates, with HSBC implementing its second rate increase within the same week and Accord adjusting its fixed residential new business rates by 0.2% as of 24 July.

What does this mean for borrowers and landlords?

For borrowers and landlords, these rate increases signify a shift in the mortgage market that could affect affordability and borrowing options. Existing borrowers looking to switch or remortgage may find that their options are now more expensive. For instance, TSB has raised its two-year fixed residential purchase and remortgage rates by up to 0.2%, with new rates starting at 4.59% for a deal at 60% LTV with a £995 fee. Virgin Money has also adjusted its product transfer rates, increasing residential pricing by as much as 0.23%.

These changes are indicative of a broader trend where rising swap rates, rather than changes to the Bank of England base rate, are influencing mortgage costs. As Rachel Geddes from the Mortgage Advice Bureau noted, the effect for borrowers is similar: mortgages are becoming more expensive.

What should borrowers and investors watch next in the mortgage market?

As the mortgage market continues to adjust to these changes, borrowers and investors should keep an eye on further announcements from lenders regarding rate adjustments. With the current geopolitical tensions and their potential impact on the economy, it is important for those in the market to stay informed about mortgage rates and consider their options carefully. Monitoring current mortgage rates and comparing products will be essential for making informed decisions.

Frequently asked questions

How do rising swap rates affect mortgage pricing?

Rising swap rates typically lead to higher mortgage pricing as lenders adjust their rates to reflect increased costs associated with borrowing. This means that borrowers may face higher interest rates on new and existing mortgage products.

What should I do if my mortgage rate increases?

If your mortgage rate increases, consider reviewing your options for remortgaging or switching to a different lender. It’s also advisable to consult with a mortgage advisor to explore the best available rates and products.
