Why are mortgage rates today rising even if central banks have not cut yet?

Markets price future inflation and growth. When oil jumps or data show sticky prices, bond yields rise. Lenders then add a spread to those yields, lifting fixed mortgage quotes. So mortgage rates today can move higher long before any policy rate cut arrives.

How does the 10-year Treasury yield affect UK mortgage pricing?

Global investors compare returns across markets. If the 10-year Treasury yield rises, gilt yields often move in the same direction. UK lenders fund and hedge off gilts, so higher gilt yields can nudge fixed-rate mortgages up. This is why mortgage rates today react to US bond moves.

What does this mean for the UK spring housing market?

Higher mortgage rates today can reduce buyer budgets and slow chains, pushing sellers to price more keenly. Cash buyers gain leverage. If inflation cools and yields fall, activity can stabilise. If yields stay high, expect fewer completions and longer marketing times into late spring.

Should I lock a rate now or wait for better pricing?

If you have a near-term completion, securing a rate with a free switch option is sensible. That protects you if mortgage rates today rise, but lets you improve terms if pricing falls. If your timeline is longer, monitor inflation and wage data and keep documents ready to act.
