Today’s Autumn Budget may have provided some much-needed encouragement for mortgage borrowers, with government borrowing costs falling immediately after the Chancellor’s announcement.

The important question for homeowners is simple: could this eventually mean lower mortgage rates?

Possibly — but we’re not there yet.

Why the Budget matters for mortgage rates

Mortgage rates aren’t determined by the Bank of England’s base rate alone.

Fixed mortgage pricing is heavily influenced by financial market expectations and, in particular, swap rates. These often move alongside government bond, or gilt, yields.

In the run-up to the Budget, government borrowing costs had risen sharply. The UK 10-year gilt yield reached around 5.52% earlier this month, putting additional pressure on the cost of funding fixed-rate mortgages.

Following today’s Budget, the 10-year gilt yield fell to around 5.32%.

That may not sound like a dramatic movement, but direction matters.

It suggests financial markets were at least partly reassured by the Chancellor’s plans for government borrowing and spending.

If that improvement continues, it could eventually give mortgage lenders more room to reduce fixed rates.

Mortgage rates have been moving higher

The Budget arrives after a difficult few months for mortgage borrowers.

Average new mortgage rates have moved towards 6%, with Moneyfacts data showing the average rate across new mortgages at approximately 5.88% immediately before the Budget.

Two-year fixed rates have been particularly affected, with the average moving close to 6%.

That means anyone whose existing mortgage deal is coming to an end could be facing considerably higher monthly payments than they have been used to.

Could mortgage rates now start falling?

It is too early to say.

One positive day in the bond markets does not automatically translate into cheaper mortgages tomorrow.

Lenders will want to see whether gilt and swap rates remain lower before making significant changes to their mortgage ranges.

There is also another major event approaching.

The Bank of England makes its next interest rate decision on 5 November. Bank Rate currently stands at 3.75%, and inflation remains above the Bank’s 2% target.

At its previous meeting, six members of the Monetary Policy Committee voted to keep rates unchanged, while three voted for an increase to 4%.

So there is still plenty of uncertainty.

What should mortgage borrowers do?

Our message remains the same: don’t try to predict exactly where mortgage rates will be in a few months’ time.

If your mortgage deal is approaching its end, start reviewing your options early.

In many cases, it may be possible to secure a new mortgage deal in advance and then continue monitoring the market. If better rates become available before completion, we can review the options again.

That gives you certainty without necessarily shutting the door on a better deal later.
