NextFin News - Shares of UK homebuilders have plunged roughly 30% since the outbreak of the conflict in Iran earlier this year, dragging valuations down to levels not seen since the 2022 market trough. According to a research note published by Goldman Sachs Group Inc. on Tuesday, this dramatic selloff has run too far, leaving investors excessively pessimistic about the sector's long-term profitability. The investment bank argues that the market has overreacted to near-term geopolitical shocks, ignoring the structural undersupply of housing in the United Kingdom.
The analysis, led by Goldman Sachs equity research analyst Rebecca Parker, reflects a structurally constructive stance on British residential developers. Parker, who initiated coverage on the sector in November 2025 with a highly positive outlook and buy ratings on three major builders, has long maintained that falling interest rates and demographic pressures will drive a multi-year recovery in homebuilding volumes. While her optimistic projections have previously been tested by macroeconomic volatility, her team continues to argue that the acceleration of earnings per share and the recovery of return on capital are not yet captured in current share prices.
This constructive view, however, does not represent a broad consensus across Wall Street or the City of London. While some institutions, including JP Morgan Chase & Co., have recently agreed that the risk-reward balance is turning positive with the sector trading at just 0.7 times tangible net asset value, the wider market remains deeply cautious. Most sell-side analysts and fund managers view the housebuilding sector with skepticism, pointing to the immediate operational headwinds that threaten to derail any near-term recovery.
The primary source of anxiety is the economic fallout from the ongoing conflict in the Middle East. The war has disrupted global supply chains and driven up energy costs, with some developers warning that the cost of building a new home has spiked by as much as €15,000 to €20,000. Major UK housebuilders have issued warnings that these rising material costs, combined with eroding profit margins, could push highly leveraged firms into a debt crunch. Furthermore, the conflict has revived fears of stagflation, making it highly uncertain whether the Bank of England can proceed with its planned monetary easing.
Goldman's bullish thesis rests on several critical assumptions that could easily prove invalid. Parker's team expects mortgage rates to decline by 78 to 86 basis points by December 2026, assuming the Bank of England cuts its benchmark rate steadily. They also rely on the UK government's ambitious target of delivering 1.5 million homes over five years to act as a powerful tailwind. Yet, if inflation remains sticky due to geopolitical tensions, mortgage rates are likely to stay elevated, further depressing homebuyer affordability. Under such a scenario, the projected recovery in residential investment—which Goldman's own economists previously warned could drag down UK gross domestic product—will fail to materialize, leaving investors who buy the dip exposed to further losses.
