Global financial markets rallied on Wednesday after a surprise ceasefire agreement between the United States and Iran eased fears of a prolonged conflict in the Middle East.
European stocks opened sharply higher, with the Brussels exchange jumping nearly 3% in early trading. The positive momentum quickly spread across Asia, where major indices posted strong gains. Japan’s Nikkei 225 surged more than 5%, while South Korea’s KOSPI climbed over 7%, reflecting investor relief in energy-dependent economies.
Markets in Hong Kong and Shanghai also advanced, rising close to 3% and 2% respectively, as geopolitical tensions temporarily cooled.
At the same time, energy markets moved in the opposite direction. European gas prices dropped dramatically, with the Dutch TTF benchmark falling nearly 20% shortly after trading began. Oil prices also declined amid expectations that supply disruptions would ease.
Central to this shift is the anticipated reopening of the Strait of Hormuz, one of the world’s most critical energy corridors. The narrow waterway handles a significant share of global oil and gas shipments, and any disruption there typically sends prices soaring.
The ceasefire, announced by Donald Trump via his Truth Social platform, includes a two-week suspension of military operations. The move follows escalating tensions and threats of large-scale strikes on Iranian infrastructure.
Meanwhile, the United Nations welcomed the agreement, urging both sides to fully comply and avoid further escalation.
Background: the US–Iran conflict
The US–Iran standoff has been one of the most volatile geopolitical flashpoints in recent decades. Tensions intensified after the Killing of Qasem Soleimani, a senior Iranian military commander, triggering a cycle of retaliatory threats and regional instability.
At the heart of the conflict are disputes over Iran’s nuclear ambitions, US sanctions, and influence across the Middle East. The Strait of Hormuz has repeatedly been used as leverage, with Iran threatening to block it in response to Western pressure—raising global energy security concerns.
Although this latest ceasefire is temporary, it signals a possible opening for diplomacy. However, analysts remain cautious, noting that previous de-escalation efforts have often been short-lived.
Why markets reacted so strongly
Markets surged for three main reasons:
- Reduced geopolitical risk: Investors moved back into equities as fears of war eased.
- Energy supply stability: Reopening the Strait of Hormuz lowers the risk of shortages.
- Falling energy costs: Lower oil and gas prices are positive for global economic growth.
