The most dramatic signal of a global housing supply crunch came this week from Washington, where new data revealed that US home construction fell off a cliff in May. Housing starts plunged 15.4 percent to an annualised rate of 1.18 million units, the slowest pace in six years and far below all economist forecasts. Building permits also slipped, and single‑family starts edged lower, as homebuilders across the country opted to focus on clearing existing inventory rather than breaking new ground. The figures, viewed from New York and London, reinforce fears that high borrowing costs and stubborn affordability challenges are forcing a broad retrenchment in the world’s largest economy.

A parallel cooling is evident in Russia, though it manifests differently. In cities of over a million people, the price premium commanded by new‑build flats over secondary market homes is shrinking. In Nizhny Novgorod, the gap narrowed from 21 to 15 percent over the past year; in Perm, from 29 to 24 percent; and in Kazan, from 17 to 13 percent. Analysts in Moscow interpret this convergence as a sign that developers are losing pricing power, while buyers increasingly turn to cheaper existing stock. The trend suggests that even where construction continues, the appetite for expensive new units is waning.

In Tehran, the situation is starker. Construction projects have been halted or abandoned as builders confront a toxic mix of soaring land and material costs, scarce financing, and bureaucratic delays. According to local real estate representatives, loans that once covered a meaningful share of construction expenses have seen their effective contribution collapse. Meanwhile, the purchasing power of potential buyers has eroded so severely that completed homes often sit unsold. The Iranian case illustrates how macroeconomic instability can paralyse supply even where underlying housing need is acute.

Switzerland, by contrast, enjoys economic stability yet faces its own persistent housing shortage. Voters recently rejected an initiative to cap population growth, implicitly endorsing the view that the answer lies in building more homes. But construction volumes have fallen from an average of over 51,000 units per year before 2020 to fewer than 46,000 in the subsequent period, while household formation continues to rise. Swiss policymakers have identified the necessary solutions—streamlining permits, coordinating fragmented responsibilities—but implementation remains sluggish. The gap between political consensus and on‑the‑ground delivery has become a defining feature of the crisis.

Taken together, these snapshots reveal a global housing sector under severe strain, though the pressures vary by region. In the United States, the primary brake is demand‑side, as high interest rates deter buyers and discourage builders. In Iran, supply has been crushed by cost escalation and economic dysfunction. Russia’s narrowing price spread hints at a market quietly repricing risk. Switzerland’s paralysis, meanwhile, is a reminder that even wealthy nations struggle to translate identified solutions into cranes on the skyline. Without concerted policy action—whether through cheaper financing, regulatory reform, or direct public investment—the shortage of affordable, available homes is likely to deepen across much of the developed and emerging world.
