100 Days of War: US-Israel Conflict With Iran Leaves Thousands Dead and Global Markets Shaken

One hundred days after the outbreak of the US-Israel war on Iran, the conflict continues to reshape the Middle East and impact the global economy despite ceasefire efforts and ongoing diplomatic negotiations.

According to data compiled by Al Jazeera, more than 7,000 people have been killed since fighting began on February 28, 2026. The casualties include 3,593 deaths in Lebanon, 3,468 in Iran, 29 in Gulf countries, 26 Israelis, and 13 American soldiers.

Lebanon Bears the Heaviest Burden

Although a ceasefire between Israel and Lebanon took effect in April, military operations have continued in southern Lebanon. Israeli forces now control nearly 20 percent of Lebanese territory, advancing farther north than initially declared objectives.

The conflict has displaced more than one million Lebanese residents, while widespread destruction of towns and villages has forced many families from their homes.

Iran has also suffered large-scale displacement, with more than three million people reportedly uprooted during the first weeks of the war as air strikes targeted infrastructure and civilian areas.

Strait of Hormuz Disruption Shakes Global Trade

The war has severely affected shipping through the Strait of Hormuz, one of the world's most important energy routes.

Before the conflict, around 100 ships passed through the strait daily. Since the fighting began, traffic has fallen dramatically to an average of fewer than seven ships per day. Hundreds of vessels remain stranded, disrupting oil and gas exports and increasing transportation costs worldwide.

The reduced flow of energy supplies has created significant pressure on global markets and raised fears over long-term supply shortages.

Rising Oil and Fuel Prices Worldwide

Global oil prices have surged since the war started. Brent crude rose from approximately $70 per barrel before the conflict to nearly $120 at its peak, before settling around $100.

The increase has affected consumers worldwide. Reports indicate that petrol prices have risen in at least 146 countries. Nigeria is among the nations experiencing substantial increases, with fuel costs reportedly more than 50 percent higher than before the conflict.

Higher energy prices have also pushed up the costs of food production, transportation, fertilizers, and many everyday products, contributing to inflation across multiple regions.

Financial Markets Face Volatility

International stock markets initially suffered heavy losses as investors reacted to fears of a prolonged regional conflict and energy crisis.

While some markets later recovered, especially technology-focused indexes in the United States, investors continue to react sharply to developments in the conflict and diplomatic negotiations.

Analysts warn that prolonged instability could slow global economic growth and increase the risk of recession.

Peace Talks Continue Without Breakthrough

Several rounds of negotiations between the United States and Iran have taken place, including talks hosted by Shehbaz Sharif in Islamabad.

A ceasefire agreement brokered in April temporarily reduced hostilities, but disagreements over Iran's nuclear programme and continuing military actions have prevented a lasting settlement.

Political analysts say mistrust between Washington and Tehran remains a major obstacle to reaching a comprehensive peace agreement.

Uncertain Road Ahead

As the conflict enters its fourth month, sporadic attacks continue despite diplomatic efforts. The humanitarian crisis in Lebanon and Iran remains severe, while disruptions to energy supplies continue to affect economies around the world.

With negotiations repeatedly stalling and military operations ongoing, the prospects for a permanent resolution remain uncertain.
