Asia-Pacific Markets Surge as US-Iran Deal Ends 107-Day War and Unlocks Oil Supply

Tokyo, Monday, 15 June 2026.
Stock markets across Asia soared by up to 5.7% on Monday after the US and Iran announced a historic deal to end their 107-day war, lifting sanctions and reopening the Strait of Hormuz—a critical chokepoint for 20% of global oil. The breakthrough sent oil prices plunging 4.5%, easing inflation fears just days before the US Federal Reserve’s rate decision. But the deal’s fine print reveals tensions: Iran will manage the strait under its sovereignty, while the US insists on toll-free access. With $24 billion in frozen assets at stake and nuclear talks looming, investors are betting on stability—even as Israel’s strikes in Lebanon and lingering infrastructure damage threaten a fragile peace.
