Barclays has cut mortgage rates days before an expected Bank Rate rise. How fixed rates really get set
Barclays cut fixed rates two days before an expected Bank Rate rise. Why that can happen, and what swap rates and lender margins tell you.
Barclays cut fixed mortgage rates by as much as 0.30 points on Tuesday 3 November 2026 (Mortgage Soup, 2 November 2026), two days before the Bank of England is widely expected to raise Bank Rate from 3.75% to 4% (What Mortgage, 2 November 2026).
A rate rise on the way and a lender cutting anyway looks like a contradiction. It isn't, and the reason explains how most UK mortgages are priced.
Bank Rate isn't what sets a fixed rate
Bank Rate feeds through to tracker mortgages almost straight away (What Mortgage). Fixed rates work differently.
Lenders mostly fund themselves through deposits and other money tied to short-term rates, so promising a fixed rate for two or five years leaves them exposed if those costs climb. They cover that risk with interest rate swaps. In the words of the lenders' trade body, "A swap rate is the cost to a lender of protecting itself against future interest rate movements" (IMLA).
Swaps look forward. "Swap rates move on what financial markets expect to happen to interest rates in the future, not where they are today," says Nick Mendes of John Charcol (What Mortgage).
This year shows it clearly.
| Benchmark | December 2025 | 30 October 2026 |
|---|---|---|
| Bank Rate | 3.75% | 3.75% |
| Two-year swap (estimate) | 3.54% | 4.74% |
| Five-year swap (estimate) | 3.70% | 4.78% |

Bank Rate hasn't moved since 18 December 2025 (Bank of England), yet swaps are more than a point higher. Fixed rates climbed with them, and most lenders have already priced in this week's expected rise (What Mortgage). So a rise on Thursday wouldn't by itself push fixes up.
Why a lender can cut now
Swaps have eased a little: down 0.04 to 0.05 points in the week to 30 October (Mortgage Compare). The 10-year gilt yield, another funding benchmark, fell below 5.3%, its lowest in more than a month (Walter's Watch, 30 October 2026).
The rest is competition, and it shows in the gap above swaps. Barclays' five-year remortgage fix at 60% loan to value (LTV) fell from 5.32% to 5.10% (The Intermediary, 2 November 2026), about 0.32 points above the five-year swap estimate. The market average five-year fix was 6.00% on 2 November (Moneyfacts via HomeOwners Alliance), about 1.22 points above it.
That gap covers more than a lender's margin. Averages span the whole market, including bigger loans against a home's value, and fees differ too. Barclays' own fee-free two-year purchase fixes show the LTV effect: 5.20% at 75% and 5.30% at 80% (Mortgage Soup).
Brokers disagree on what it means. "Barclays has blinked first and now the fun starts," says David Stirling of Mint Wealth, who suggests a possible mini price war. Elliott Culley of Switch Mortgage Finance thinks Barclays had priced too high, and doesn't see it as a sign rates are falling (both Brit Brief, 2 November 2026).
What moves fixes from here
Thursday's decision matters less for fixes than the signal on what follows. Markets price further rises in 2027, and if the Bank points to fewer, swaps could ease. Fidelity International's Conor Parle expects "slightly fewer rate hikes than markets currently expect" (HomeOwners Alliance, 2 November 2026).
Plenty of households will feel the outcome: about 2.3 million face a mortgage renewal in 2027 (The Independent, 2 November 2026).
What a small cut means in practice
On an illustrative GBP 200,000 loan over 25 years, the free Overpayment calculator in Stresst shows 5.32% at GBP 1,207 a month and 5.10% at GBP 1,181. Keep paying GBP 1,207 at 5.10% and, with that rate held for the full term, the loan clears a year sooner with GBP 7,529 less interest.

The worked example above came out of the Stresst app, and you can run your own in a couple of minutes. Overpayment and the Remortgage Calculator are free, and a 7-day free trial opens Premium tools such as UK Affordability.
With the Bank of England deciding on Thursday, this is a good week to know where your own loan stands. On iPhone, Stresst is in beta through Apple's TestFlight app.
