Mortgage Rates on the Rise Again… Here’s What It Means If You’re Mid-Application
Keeping half an eye on mortgage rates this week? You’ll have noticed a few big names moving the wrong way. Halifax and Barclays have raised rates across large parts of their ranges. HSBC has followed suit. It comes just days after NatWest, Nationwide, Coventry and Virgin Money did the same.
None of this is random. It’s the latest ripple from the market volatility tied to the conflict in Iran. That volatility has pushed up swap rates, the rate lenders actually borrow at when they price a fixed mortgage deal. When swaps move, lenders reprice. They’ve been doing it in both directions over the past few months as the situation shifts.
Why Lenders Move Rates Even When the Base Rate Hasn’t
This is the bit that catches people out. The Bank of England base rate and your mortgage rate aren’t the same thing, and they don’t move together. Swap rates set the price of fixed deals. They reflect what the market expects over the next two, five or ten years, not what the Bank has actually decided today. That’s why a lender can hike its fixed rates in a week the Bank does nothing at all.
Tracker rates are a different story. They move in step with the base rate itself. That’s part of why this week’s changes included smaller tracker increases too, not just fixed-rate hikes.
What This Actually Means Depending on Where You Are
You haven’t applied yet. Rate rises like this are a good prompt to sort a mortgage agreement in principle sooner rather than later. Then you’ll know what you’re working with before you make an offer.
You’ve got an agreement in principle but haven’t picked a property. An AIP doesn’t usually lock your rate. The formal application does that, so there’s a decision to make about timing.
You’re mid-application with a rate on hold. Most lenders let you hold a rate for a set window, often 3-6 months, while your application and purchase move through the process. Have you already secured your offer? This week’s changes shouldn’t touch you.
Your current rate reservation is about to expire. This is where it’s worth a call sooner rather than later. Let your hold period lapse before you complete, and your lender could switch you onto whatever rate is on the shelf at that point.
Should You Rush to Lock In a Rate?
Not necessarily. It’s worth being wary of anything that pushes you towards a decision out of panic rather than fit. Rates have moved in both directions through 2026 as the situation with Iran has developed. Hikes followed cuts, then more hikes. Locking in isn’t really about guessing the next move. It’s about whether the rate on offer works for your budget today, given what you know now.

Frequently Asked Questions
Why do mortgage rates rise even when the Bank of England hasn’t changed the base rate? Swap rates set the price of fixed mortgage deals. They reflect what financial markets expect to happen to interest rates over the length of your deal, not the Bank’s rate on the day. Swap rates have been moving because of the conflict in Iran. That’s why lenders keep repricing without a base rate change.
Will my mortgage offer change if rates rise after I’ve applied? Usually not, provided you’ve already secured your rate through a formal application. Most lenders hold that rate for a set window while your purchase completes. Only if that hold period expires before you finish would new pricing apply to you.
Are tracker rates affected the same way as fixed rates? No. Tracker rates move directly with the Bank of England base rate, so they only change when the Bank moves. This week’s tracker increases were smaller than the fixed-rate changes for that reason.
Should I fix now before rates rise further? That depends on your own situation and timeline more than trying to predict the next move. Rates have gone up and down several times already this year. It’s worth talking it through rather than reacting to headlines alone.
How long can I hold a mortgage rate before it expires? It varies by lender, but a typical rate reservation window runs 3 to 6 months from application. Check your offer paperwork or ask your broker for your specific expiry date.
