US-Iran Ceasefire: Impact on Global Markets and Oil Prices

Global stock markets surged and oil prices dropped sharply on April 8, 2026, following the announcement of a conditional two-week ceasefire between the United States, and Iran. The Dow Jones Industrial Average recorded its single largest one-day percentage gain since April 2025, jumping 1,325 points as investors reacted to the potential pause in a conflict that began on February 28, 2026.

The ceasefire, which was brokered by Pakistan, was announced by President Donald Trump on the evening of April 7, 2026. The agreement includes a suspension of U.S. Bombing and attacks on Iran, provided that the Islamic Republic of Iran ensures the COMPLETE, IMMEDIATE, and SAFE OPENING of the Strait of Hormuz.

Market Reactions and Index Performance

The response from financial markets on April 8, 2026, was overwhelmingly positive across multiple regions. In the United States, the S&P 500 closed up 2.5%, the Nasdaq Composite ended higher by 2.8%, and the Russell 2000 surged 2.9%.

International indices mirrored these gains. In Asia, Japan’s Nikkei 225 closed up nearly 5.4% and South Korea’s Kospi jumped more than 6.8%. Hong Kong’s Hang Seng ended the day 3% higher, and the ASX 200 in Australia gained 2.5%.

European markets also saw significant growth. Germany’s Dax climbed 4.7% and France’s CAC 40 ended the day 4.5% higher, while London’s FTSE 100 share index closed up 2.5%.

Strategists at JPMorgan Chase noted that the S&P 500 could continue to rise as euphoria returns to markets. The firm suggested that if the ceasefire is not a feint, the market is likely to view the agreement as a de facto end of the conflict, despite remaining economic damage across various regions.

Oil Price Volatility and Energy Impact

Global oil prices experienced a sharp decline following the news. The global benchmark oil price initially sank 15% to just under $92 per barrel before recovering slightly. US-traded oil dropped to approximately $96 per barrel.

Despite the drop, prices remain significantly higher than they were before the conflict began on February 28, 2026, when oil was trading at approximately $70 per barrel. Energy costs had escalated due to severe disruptions in Middle East supplies after Iran threatened to attack ships using the Strait of Hormuz in retaliation for U.S. And Israeli airstrikes.

Uncertainty Over the Strait of Hormuz

While markets responded positively, the operational status of the Strait of Hormuz remains contested. Iranian state TV reported that a first vessel had transited the chokepoint with Tehran’s permission following the ceasefire. However, shipping sources reported that the Iranian navy continued to threaten ships with destruction if they attempted to pass.

Further complicating the situation, an Iranian semiofficial news agency reported on April 8, 2026, that traffic in the Strait of Hormuz was suspended in response to Israeli attacks on Lebanon.

Regional Conflict and Infrastructure Damage

The ceasefire comes amid broader regional violence. On April 8, 2026, Israel launched its largest attacks to date on Lebanon, targeting the Iran-backed Hezbollah militia and destroying buildings, according to Lebanese authorities. Iran stated it was considering strikes against Israel in response.

oil industry sources report that Iran struck oil facilities in neighboring Gulf countries. These attacks included a major pipeline in Saudi Arabia that had been utilized to bypass the blockaded Strait of Hormuz. Missile and drone strikes were also reported in Kuwait, Bahrain, and the UAE.

Economic Outlook and Risks

Some economists have cautioned that the market’s optimism may be premature. Krishna Guha, head of economics and vice chairman at Evercore, stated in a memo on April 8, 2026, that We are not out of the woods yet.

Guha warned that the ceasefire could collapse and that the global economy will still face an initial inflation shock.

The U.S. Government has stated it has stopped its attacks on Iran but remains prepared to resume fighting if efforts to secure a more lasting peace agreement fail.
