Iran war’s big winners: Wall Street, weapons firms, AI and green energy

A US-Israeli war on Iran in 2026 has led the IMF to downgrade global growth forecasts due to damaged energy infrastructure and the shutdown of the Strait of Hormuz. The global economy faces potential recession, with developing nations hit hardest by rising commodity prices and shipping crises. Despite the grim outlook, some industries are thriving. Wall Street investment banks are profiting from increased trading volume driven by market volatility. The war has also created opportunities for weapons firms, artificial intelligence companies, and the green energy sector. These industries benefit from the uncertainty and changing demands caused by the conflict.

Asian stocks declined on Friday, April 17, 2026, despite Wall Street's record high, as investors awaited further developments in U.S.-Iran talks and the potential extension of the Iran war ceasefire. The Nikkei 225, Kospi, Hang Seng, Shanghai Composite, and S&P/ASX 200 all experienced losses. Oil prices also fell, with Brent crude dropping 1.1% to $98.31 per barrel and U.S. crude down 1.4% to $89.90 a barrel, following a surge since the war's beginning. Optimism surrounding a possible ceasefire extension grew after President Trump indicated openness to it and Iran expressed cautious optimism. The International Energy Agency warned of potential jet fuel shortages in Europe due to the ongoing conflict and the closure of the Strait of Hormuz.
