The BoE Just Held at 3.75% for the Sixth Straight Month. Your 4.66% Fixed Rate Is a Bet Against Every Signal the Market Is Sending.

The mortgage market is pricing fixes as if the base rate were still 4.50%. It isn't. It's 3.75%, and it's been falling — from 5.25% in August 2023, to 5.00%, 4.75%, 4.50%, 4.25%, 4.00%, and finally 3.75% in December 2025. That's 150 basis points of cuts in 28 months.

And yet the spread between the base rate and fixed mortgage rates has widened. In a normal market, a 5-year fix at 75% LTV might sit 0.50-0.75% above the base rate. Today it's 0.91% above. Lenders are pricing in a risk premium that the data doesn't support. The Financial Conduct Authority tracks mortgage market pricing, and the spread between the base rate and fixed-rate mortgages is at its widest since early 2024. — and borrowers are paying it.

Let's put numbers on this. At 3.75% base rate, a tracker at base + 0.21% (the best available at 60% LTV) gives you 3.96%. The cheapest big-six 5-year fix at 75% LTV is 4.66%. The spread is 0.70 percentage points. On a £200,000 mortgage: £75 a month, £900 a year, £4,500 over five years. That's the certainty tax.

Yes, UK gilt yields have risen from 4.43% in February to 4.94% in May — a 51-basis-point increase. Fixed-rate defenders point to this and say: swap rates are rising, fix now before they go higher.

This gets the causal chain backwards. Gilt yields are rising partly because the market expects the Bank of England to hold rates higher for longer — not because it expects them to rise. There's a difference between "rates staying at 3.75% through 2026" and "rates climbing back to 5.25%." The gilt market is pricing the first scenario. Fixed-rate mortgage premiums are pricing something closer to the second.

More importantly, gilt yields reflect the government's borrowing costs, not your mortgage rate destiny. The spread between gilts and mortgage rates has been unusually wide since the mini-budget episode of 2022, and lenders have been slow to compress it on the way down. They were quick to reprice upward when rates rose. They're slow to reprice downward as rates fall. That asymmetry is the lender's profit margin — not a signal you should act on.

The case for fixing always invokes the nightmare: inflation spikes, the Bank panics, rates hit 7%, and your tracker payment explodes. It's a compelling story. It's also a story that requires ignoring everything the Bank of England has said and done for the past two years.

CPI inflation is at 3% — above the 2% target, but a long way from the 11.1% peak of October 2022. UK services output is shrinking, according to the latest PMI data. The economy is losing speed. The Bank of England's own forecasts project inflation falling back toward target through 2026. The US Federal Reserve has held at 3.63% — comparable to the UK — and is facing similar disinflation dynamics.

Central banks don't raise rates into a slowing economy with inflation trending down. They just don't. The last hiking cycle (2021-2023) was a response to a global supply shock, a post-pandemic demand surge, and an energy crisis — three events that are not repeating. The Bank of England MPC minutes from June 2026 show a committee more concerned about downside growth risks than upside inflation risks. To bet on a rate reversal is to bet on a new crisis that the bond market, the central bank, and every major forecaster is not predicting.

That's not insurance. That's paying for flood cover on a house at the top of a hill.

Fixed-rate advocates warn about the SVR trap: your tracker deal ends, and you drop onto a 6.49% standard variable rate. This is a real risk — but only if you're passive. The solution is not to pay £4,500 extra over five years to avoid it. The solution is to remortgage.

You can lock in a new rate up to six months before your current deal ends. If you take a 2-year tracker today at 3.96%, you start looking for your next deal in 18 months. By then, if the cutting cycle continues, you're fixing into a rate that could be 3.25% or lower. Even if rates stay flat, you're remortgaging onto another tracker or a fix at roughly the same level.

The SVR argument only works if you assume the borrower does nothing while their deal expires. That's not financial planning — it's inertia. And paying £4,500 to protect yourself from your own inertia is an expensive workaround for setting a calendar reminder.

MoneyHelper recommends starting the remortgage process 6 months ahead — plenty of time to avoid SVR. For more on remortgaging strategy, see our mortgages hub.

Fixed rates make sense for one group: borrowers who cannot absorb any increase in their monthly payment. If your budget is stretched to the point where an extra £100 a month would cause genuine hardship, fix. The insurance is worth it — not because the risk is high, but because the consequence is unaffordable.

For everyone else — households with a savings buffer, dual incomes, or slack in their monthly budget — the tracker is the rational choice. You're being asked to pay £4,500 over five years to protect against a scenario with a low single-digit probability. The expected value is negative by a wide margin.

Consider this: if you invested that £75 monthly saving into a stocks and shares ISA returning 7% nominal, you'd have £5,380 after five years. Add that to the £4,500 in direct savings, and the tracker holder is nearly £10,000 ahead of the fixer — before we even discuss the possibility of rates falling further and widening the gap.

The comfortable consensus — "just fix, it's safer" — is expensive. It always has been. Lenders price fixes to make money, not to do you a favour. The margin embedded in today's fixed rates is unusually wide by historical standards. You're being charged a premium for fear that the data doesn't justify.
