NextFin News - The cornerstone of U.S. President Trump’s domestic agenda—a sweeping plan to revive the American dream of homeownership—is hitting a geopolitical wall as the escalating war in Iran sends shockwaves through the U.S. mortgage market. Just months after the administration unveiled a series of aggressive measures to lower housing costs, the conflict has triggered a sharp reversal in borrowing conditions, threatening to neutralize the impact of the president’s signature housing policies.
The shift is most visible in the sudden retreat of prospective buyers. Mortgage applications plunged 10% in the week ending Wednesday, according to data from the Mortgage Bankers Association (MBA). Refinancing activity, which had shown signs of life earlier in the year, dropped 15% over the same period. This cooling of demand follows a rapid ascent in borrowing costs; the 30-year fixed mortgage rate climbed to 6.38% this week, a 16-basis-point jump that marks its highest level since last September. The move tracks a broader sell-off in the bond market, where the 10-year U.S. Treasury yield has surged 51 basis points since the onset of the Iran conflict, reaching 4.47% on Friday.
Joel Kan, deputy chief economist at the MBA, attributed the decline in applications to a combination of higher rates and general economic uncertainty fueled by rising energy costs. The war has reignited fears of "higher-for-longer" inflation, as oil prices react to potential supply disruptions in the Middle East. For U.S. President Trump, the timing is particularly difficult. His administration had recently introduced a controversial 50-year mortgage product designed to lower monthly payments for first-time buyers. However, with base rates rising, the mathematical advantage of stretching a loan over five decades is being eroded by the higher interest expense required to attract investors to these long-dated securities.
The conflict also complicates the enforcement of the "Stopping Wall Street from Competing with Main Street Homebuyers" executive order signed by U.S. President Trump in January 2026. While the order aims to ban large institutional investors from purchasing single-family homes to increase supply for families, the current market volatility may achieve that goal through less desirable means. Institutional buyers are already pulling back as the cost of capital rises, but they are being joined by the very families the president intended to help, who are now priced out by the 6%-plus mortgage environment.
Not all analysts agree that the war will permanently derail the housing recovery. Torsten Sløk, chief economist at Apollo Global Management, suggested in a recent note that markets may be overreacting to the geopolitical premium. Sløk, known for his data-driven and often contrarian macroeconomic views, argued that the underlying U.S. economy remains resilient and that the Iran war may not have the sustained inflationary impact currently priced into Treasury yields. His perspective serves as a reminder that while the immediate data is grim, the long-term trajectory of the housing market still depends heavily on domestic supply-side reforms rather than foreign policy alone.
The tension between the White House’s populist housing goals and the realities of a wartime economy is creating a policy vacuum. If oil prices remain elevated, the Federal Reserve may be forced to delay any anticipated rate cuts, further anchoring mortgage rates at levels that make the president’s 50-year mortgage and anti-Wall Street measures feel like secondary concerns for the average buyer. For now, the "real progress" once touted by the administration has been replaced by a cautious wait-and-see approach from both lenders and borrowers.
