British mortgage approvals suffered their sharpest monthly drop since December 2023 in May, falling to 56,205 from 66,034 in April, according to Bank of England data. The contraction, which surprised analysts in London, was the most dramatic single data point in a synchronised global housing slowdown that has seen transaction volumes slide across France, India and Australia. The common driver is the sustained rise in sovereign bond yields—the benchmark for mortgage pricing—sparked by the US-Israeli war on Iran. France’s 10-year government bond yield reached 3.61% on Monday, a level that has fed directly into higher credit costs and eroded household purchasing power.

In France, the number of transactions fell by 11,000 units in March and April compared with a year earlier, according to the Fnaim estate-agency federation, which described the shift as a “real halt” after a brief recovery in 2025. India’s top seven cities recorded a 6% year-on-year drop in housing sales in the first quarter of 2026, data from consultant Anarock showed, with the Delhi-NCR and Mumbai regions among the worst hit. Anarock’s chairman pointed to the war’s disruptions and AI-related uncertainty in the IT sector as factors pushing buyers to the sidelines, even as developers increased new launches by 7%, signalling continued long-term confidence.

Australian markets are absorbing a double shock. Auction withdrawal rates in Sydney surged to a preliminary 39.5% on the final weekend of June, up from 21.9% a month earlier, Domain figures indicate, while Melbourne’s rate rose to 16.4%. Economists attribute the pullback not only to higher interest rates and cost-of-living pressures but also to recent federal budget changes to capital gains tax and negative gearing, which have dampened investor appetite. Prime Minister Anthony Albanese defended the reforms, citing Treasury estimates that house prices would still rise, albeit more slowly, and arguing the measures were needed to correct intergenerational inequity in home ownership.

Across markets, a pattern of seller resistance is emerging. French network Century 21 noted a contracting market where buyers’ margins are again being squeezed. In Melbourne, auctioneers report that vendors unwilling to accept lower prices are pulling properties before auction day, while opportunistic buyers make lowball offers. UK mortgage brokers observed that May’s data provided the first clear sign that larger numbers of borrowers were “sitting on their hands” amid inflation uncertainty and weaker consumer confidence.

The trajectory now hinges on whether the interim US-Iran peace agreement holds, which could ease bond yields and stabilise mortgage rates. Central bank policy meetings in Frankfurt and London will be scrutinised for any shift in tone. In Australia, the political debate over housing tax changes is set to intensify as clearance rates test multi-year lows, while developers across Asia-Pacific watch for any further erosion of buyer sentiment.
