TL;DR

  • •borrowers can expect higher costs across various mortgage products.

The UK mortgage market is experiencing significant upheaval as rising swap rates lead to increased mortgage pricing across various lenders. This shift is primarily driven by geopolitical tensions, particularly the escalating conflict between the US and Iran, which has resulted in oil prices reaching $100 per barrel for the first time since May. Borrowers are now facing higher costs as lenders adjust their offerings in response to these market changes.

What are the current changes in the mortgage market?

As of July 22, the two-year swap rate increased significantly to 4.258%, up from 3.993% the previous month, while the five-year swap rate rose from 4.034% to 4.316%. These increases have prompted several lenders to adjust their mortgage pricing. For instance, Nationwide has raised rates for existing borrowers, with the two-year fixed additional borrowing product at 60% loan to value (LTV) now at 4.6%, up from 4.37%. Similarly, the 75% LTV deal has increased from 4.46% to 4.68%.

Which lenders are increasing their mortgage rates?

Multiple lenders have announced rate hikes in response to the rising swap rates. HSBC is set to implement its second rate increase this week, effective from July 27. Accord has also raised its fixed residential new business rates by 0.2% as of July 24, while TSB has increased its two-year fixed residential purchase and remortgage rates by up to 0.2%. Virgin Money has adjusted its product transfer rates, with residential pricing increasing by as much as 0.23%.

What does this mean for borrowers and landlords in the mortgage market?

For borrowers and landlords, these rate increases signify a shift towards higher mortgage costs. Existing borrowers with products from lenders like Nationwide and TSB will see their rates rise, making it more expensive to manage their mortgage payments. Landlords seeking buy-to-let (BTL) mortgages will also feel the impact, as BTL rates have risen by 0.1% across new business products. This trend could affect affordability and borrowing capacity, especially for first-time buyers and those looking to remortgage.

What should borrowers watch for next in the mortgage market?

Borrowers should keep a close eye on further developments in the mortgage market as lenders continue to adjust their rates in response to ongoing economic factors. With the Bank of England base rate remaining unchanged, the primary driver of these changes is the rising swap rates. It is essential for borrowers to stay informed about potential rate hikes and consider locking in current rates before they increase further. For those looking to compare options, checking mortgage rate comparison tools can provide insight into the best available deals.
