Mortgage rates are climbing across the West as the conflict in Iran feeds higher borrowing costs. In the United Kingdom, the average quoted two‑year fixed mortgage at a 75 % loan‑to‑value jumped to 5.1% in April, up from 3.97 % at February’s end. The rise outpaces any recent central‑bank moves, squeezing home‑buyers and refinancers for first‑time buyers.

Germany sees a more modest lift, with ten‑year mortgage yields climbing roughly 0.3 percentage points to about 3.6 %. That adds roughly €1,000 to the annual cost of a new €350,000 loan, nudging total interest to €13,000. Across the Atlantic, U.S. thirty‑year mortgage rates have crossed the 6 % threshold, settling at 6.36%, the highest level since the Fed’s 2025 rate‑cut cycle began for consumers.

Lenders are passing on higher sovereign borrowing costs even though central banks have held policy rates steady, betting that inflation pressures will eventually force official hikes. The surge adds strain to already tight housing markets, raising monthly payments for borrowers and potentially dampening demand for new homes. Investors should watch credit spreads as mortgage‑backed securities adjust to the new rate environment in the near term.
