Because banks don’t just make up mortage rate figures for fun, it goes by the swap rate (how much it costs the bank).
Other posters keep referring to a crystal ball, you don’t need a crystal ball to see where the rates are going. Look at my previous posts over the last couple of years.
Interest rates are set by the central banks and are influenced by the treasury yield rate (10 year for destination, 2 year for direction). BoE follows the Federal Reserve as do all other central banks as the US $ is the worlds reserve currency (for now)
If central banks did not raise rates in line with inflation then the economy would end up in an inflationary spiral. See Turkey as an example of what happens when you cut interest rates in the face of inflation.
We are currently behind the US in raising rates, as are the EU and Japan which is why all currencies are currently falling against a very strong US $.
So ultimately to gain direction of rates, you would need to look at the US 10 year treasury rate, which still rising.

So yes the BoE deputy may of stated that he expects rates to fall (once the US yields are under control) but they also said there wouldn’t be inflation and if it was it would be transitory. Just look at the US housing market it’s a good indicator of where we will be by next year.
