A key mortgage rate in Britain has risen to within a whisker of a high struck late last year after former prime minister Liz Truss' "mini-budget", figures from data provider Moneyfacts showed on Monday.

Average two-year fixed rates stood at 6.63%, up from 6.54% on Friday and a fraction below their peak of 6.65% on Oct. 20.

Mortgage rates have climbed sharply in recent weeks as investors increased their bets on how high the Bank of England will raise interest rates to fight high inflation.
