Global financial markets have staged a tentative comeback in recent weeks, with major stock indices clawing back losses sustained during March’s energy-driven rout — yet analysts warn that the underlying pressures driving that sell-off are far from resolved.
The S&P 500 ended the first quarter of 2026 down 4.6%, though the headline figure conceals a more turbulent story beneath the surface. Technology stocks bore the brunt of the pain, with the so-called “Magnificent 7” firms falling more than 11% as a group, while the broader equal-weighted index held up considerably better. By mid-April, a cautious optimism had returned to trading floors, with stocks continuing their climb on hopes that diplomatic efforts to ease the US-Israel conflict with Iran could bring some stability to energy markets.
The Energy Shock at the Centre of It All
The root cause of this volatility is a supply shock with few modern parallels. US and Israeli strikes on Iran disrupted flows through the Strait of Hormuz, with nearly 20 million barrels of oil and significant volumes of liquefied natural gas currently restricted. Brent crude briefly surged above $110 per barrel, prompting Goldman Sachs to sharply revise its 2026 oil price forecast upward to an average of $85 a barrel, from an earlier estimate of $77. UK gas prices doubled in a matter of days following the initial strikes, with the benchmark briefly topping 165p per therm — a level not seen since the year after Russia’s invasion of Ukraine.
The human and economic consequences have rippled well beyond the oil market. QatarEnergy, one of the world’s largest exporters, suspended production of aluminium, methanol, and fertiliser components following military attacks on its facilities. Analysts at UBS describe the situation as a “renewed energy-driven supply shock” that has pushed inflation higher and made traditional portfolio diversification harder, as conventional safe havens have proved unreliable.
Central Banks in a Difficult Position
For policymakers, the shock has sharpened an already uncomfortable dilemma. The US Federal Reserve has moved firmly into “wait-and-see” mode, raising its 2026 inflation forecast to 2.7%. The Bank of England, the European Central Bank, and the Bank of Japan have all signalled a more hawkish bias, with the ECB’s Christine Lagarde explicitly flagging the possibility of responding to a persistent inflation overshoot. Rate cut expectations that dominated market sentiment at the start of the year have largely been scaled back.
Recovery, But With Caveats
Regional equity performance has been highly uneven. Japan’s Nikkei fell 12.6% in March alone, while the FTSE 100 — bolstered by its energy-heavy composition — declined a more modest 3.9% and remains up 6.8% year-to-date. The speed of the recent equity rebound has drawn comparisons to the V-shaped recovery of April 2025, when the S&P 500 recouped a 10% plunge within a single month.
Yet analysts at Man Group caution that such rebounds are not a reliable signal of structural resilience, and that markets must now price in the possibility of policy U-turns and further geopolitical shocks. “Supply shocks do eventually end,” UBS notes — but whether the global economy can navigate this one without tipping into recession remains the question markets are yet to answer.
