Briefing Summary
AI-generatedAs of March 30, 2026, the war in Iran and the blockage of the Strait of Hormuz are causing rising French mortgage rates. This is due to the increase in state bond rates, particularly the 10-year OAT, which reached levels not seen since 2009. Consequently, many banks are increasing their rates for April, by an average of 0.10 points, with some raising them by as much as 0.30 points. This increase in rates, now between 3.30% and 3.50% for a 20-year loan, negatively impacts French citizens planning to buy property. The rising OAT rate is directly linked to increasing mortgage rates for individuals.
