Roll up. Roll up. Good mortgage rates, going fast.

After a period when borrowers had been hoping rates would continue to fall, things have changed.

Rising bond yields and swap rates have increased the cost of funding mortgages. Lenders have responded by putting up rates and repricing deals.

And that means some of the attractive mortgage rates available today may not hang around for long.

Why are mortgage rates going up?

Fixed mortgage rates aren't driven by the Bank of England base rate alone.

They're heavily influenced by swap rates – essentially the market's view of where interest rates are heading in the future.

When swap rates rise, it becomes more expensive for lenders to fund fixed-rate mortgages. That can quickly feed through into the rates offered to borrowers.

And that's what we're seeing now.

Several major lenders have already increased mortgage rates, with the potential for further repricing if market pressures continue.

Don't wait until your mortgage ends.

If you're remortgaging, one of the biggest mistakes you can make is leaving everything until the last minute.

You can often start looking at your options several months before your existing deal ends.

That matters in a rising-rate environment.

Talk to Moat early, and we can look at your circumstances, search the market and show you what's available now.

If there's a deal worth securing, depending on the lender and your circumstances, you may be able to get the process underway well before your existing mortgage finishes

There's another good reason to start early.

Getting your remortgage organised doesn't necessarily mean you have to stop watching the market.

If rates rise, you may be pleased you've already secured a deal.

If rates fall before your new mortgage starts, depending on the lender and product, we can look again and see whether there's a better option available.

A small rate rise can mean a bigger monthly bill.

Even relatively small changes in mortgage rates can make a noticeable difference to your repayments. And the larger your mortgage, the greater the potential impact.

So waiting in the hope that a better deal will turn up can be a gamble, particularly when lenders are already moving rates in the opposite direction.
