Single-family homebuilding in the United States dropped in May to its weakest level since last September, as higher mortgage rates and rising material costs squeezed builders. The pullback comes as financial markets bet heavily that the Federal Reserve will leave interest rates unchanged at its July meeting, a move that could keep borrowing costs elevated for months.
May's housing slump
Construction starts on single-family homes fell sharply last month, hitting an eight-month low. Builders cite two main pressures: mortgage rates that have climbed back above 7% and persistently high prices for lumber, concrete, and other inputs. The combination has made it harder for developers to start new projects, especially for entry-level homes where margins are thin.
“We're seeing a real slowdown in new projects,” said one builder in the Southeast, speaking on condition of anonymity because the company's internal data isn't public. “Permits are down, and we're not rushing to break ground unless we have a buyer lined up.” The drop follows a brief recovery earlier this year when rates dipped slightly, but that momentum has faded.
Rate expectations firm
On prediction market Polymarket, traders now see a 91.5% probability that the Fed will hold interest rates steady when it concludes its July policy meeting. That would keep the federal funds rate in the current 5.25%-5.50% range, the highest in more than two decades. The expectation has hardened after recent data showed inflation remaining stubbornly above the central bank's 2% target.
If the Fed does hold, mortgage rates are unlikely to fall significantly in the near term. That would extend the pressure on homebuilders, who have already scaled back plans. “There's no catalyst for a rate cut in July,” said a bond trader at a major bank. “The housing market is going to stay in this slow lane for a while.”
What the numbers mean for buyers
The decline in building is bad news for potential homebuyers already facing a tight inventory. Fewer new homes coming to market means less competition among sellers, which can keep prices from falling even as demand softens. The National Association of Home Builders reported that builder confidence dipped in May, and the latest starts data confirms that hesitation is translating into fewer projects.
Material costs are another wild card. Lumber prices spiked again in late spring after Canadian mills cut output, and concrete costs remain elevated due to fuel surcharges. Builders say they are passing those costs on to buyers, making new homes even less affordable.
The question now is whether the Fed's next move—expected to be a rate cut sometime later this year—will come soon enough to revive homebuilding. The prediction markets offer little hope for July, but traders will be watching the next inflation report due in mid-June for any sign that price pressures are easing.
