Why have mortgage rates gone up when the Bank of England base rate hasn’t changed?
We’ve had several clients asking this question recently, and it’s a completely fair one.
At first glance, it can feel confusing. If the Bank of England base rate hasn’t moved, why are mortgage rates increasing?
The answer lies in how mortgage pricing actually works.
Base Rate vs SWAP Rates: What’s the Difference?
While the Bank of England base rate often makes the headlines, it’s not the main factor lenders use to price fixed-rate mortgages.
Instead, mortgage rates are more heavily influenced by SWAP rates.
- Base rate = where interest rates are today
- SWAP rates = where markets expect interest rates to be in the future
SWAP rates reflect forward-looking expectations. Lenders use them to set pricing on fixed-rate deals because they’re effectively predicting what it will cost to lend money over the coming years.
Why Are SWAP Rates Rising?
Recently, SWAP rates have increased due to heightened global uncertainty.
Factors such as ongoing geopolitical tensions, including conflict in the Middle East, have made financial markets more cautious.
When uncertainty rises, markets tend to:
- Anticipate higher future borrowing costs
- Build in additional risk
- Push SWAP rates upward
As a result, lenders adjust their fixed mortgage rates, even if the base rate hasn’t changed.
What This Means for Mortgage Rates
In simple terms, mortgage rates can rise without any movement in the base rate because lenders are reacting to future expectations, not just current conditions.
This is why we sometimes see:
- Fixed mortgage rates increasing
- New deals being repriced
- Lenders adjusting products quickly
A Bit of Reassurance
It’s important to keep this in perspective.
- Markets can be volatile, but they also settle
- Short-term spikes don’t always lead to long-term trends
- If you’re on a fixed rate, you’re protected for now
- There are still competitive options available for those approaching renewal
What Should You Do Next?
If your mortgage deal is ending in the next 6 months, it’s worth reviewing your options sooner rather than later.
Planning ahead allows you to:
- Secure a rate now if needed
- Retain flexibility in case rates improve
- Avoid last-minute pressure
Final Thoughts: Don’t Panic – Plan Ahead

The key is not to react emotionally, but to make informed, proactive decisions.
