Introduction
Swap rates hold significant sway on mortgage rates, particularly the Sterling Overnight Index Average (SONIA) swap rates within the UK market. We will look into what swap rates are and their effect on mortgage rates.
What is an Interest Rate Swap?
Interest rate swaps involve a contractual deal where two parties exchange sets of interest payments over a pre-agreed duration. This financial instrument is fundamental in understanding how lenders manage the risk associated with interest rate fluctuations.
The Role of SONIA Swap Rates
SONIA, which overtook the London Interbank Offered Rate (LIBOR) in 2021, has become the foundation of interest rate benchmarks in the sterling markets.
For mortgages, these swap rates are a defence mechanism for lenders against the volatility of interest rates, providing a safeguard to lock in profit margins irrespective of fund cost changes, such as variations in the base rate.
Not all banks will rely on swap rates; some may choose natural hedges like savings bonds. Lenders that use swap rates have a range of term options, ranging from 1 to 30 years, depending on their risk management strategies.
Swap rates are essentially the market’s temperature check on future Bank interest rates, rooted in expectations and broader economic indicators like inflation and general economic health.
Understanding 2-year and 5-year UK Swap Rates
The 2-year and 5-year swap rates represent the collective market forecast of interest rates over the next two or five years, respectively. These are critical benchmarks for lenders in pricing their mortgage offerings as the majority of mortgages are written with a fixed rate of 2 or 5 years.

The Volatility of Swap Rates
Swap rates can be volatile. Factors stirring this volatility include base rate rises, inflation concerns, market sentiment, and geopolitical tensions.
Impact of Swap Rates on Mortgage Rates
It is key to note that swap rates primarily influence fixed-rate mortgages. A higher swap rate leads to an escalated mortgage rate, on top of the lender’s risk and appetite considerations. Volatile swaps can unsettle lenders’ pricing strategies as they increase their margin, and, sometimes leading to a temporary withdrawal of products from the market as they recalibrate.
Current Mortgage Rate Trends
While it’s not possible to predict future market movements with absolute certainty, mortgage rates will likely remain responsive to inflation trends and base rate projections which are reflected in the swap rates.
Other Factors that affect Mortgage Rates
Beyond swap rates, a multitude of elements factor into mortgage pricing. These include the Bank of England base rate, lender-specific goals, competitive positioning, and service capacity, among others.
An uptick in the base rate directly affects tracker mortgages but does not alter the monthly payments for existing fixed-rate mortgages until the term concludes and remortgaging is required.
