UK mortgage rates have risen for the first time since the Easter period, driven by renewed fighting in the Middle East that is reigniting inflation concerns among lenders.
Analysis from financial comparison site Moneyfacts indicates that 13 major lenders have increased borrowing costs in response to the escalating geopolitical risk.
The rate hikes present a significant political complication for Labour leader Andy Burnham as he prepares to enter Downing Street.
The move undermines efforts to stabilize household finances and comes at a time when the new administration is expected to face intense scrutiny over its economic management.
This development adds to a week of market volatility for UK assets.
Equity markets have faced renewed selling pressure as investors digest reports that Burnham is preparing a significant policy overhaul.
