Details of Oil Supply Interruption in Hormuz in Report

20 PERCENT OF OIL SUPPLY WAS PASSING THROUGH HORMIS

Before the US/Israel-Iran War, approximately 20 percent of global oil supply and approximately 20 percent of global LNG trade passed through the Strait of Hormuz.

During the peak period of the outage, 14 percent of global oil and gas supplies were disrupted. According to the report, this rate corresponded to approximately twice the impact of oil shocks in the 1970s and approximately six times the peak impact of the Russia-Ukraine War in 2022.

The direct impact on natural gas was more limited. Approximately 3 percent of global gas supply was affected. Although one fifth of global LNG trade passes through the Strait of Hormuz, it was stated that LNG's share in global gas supply is less than 15 percent.

A DAILY DEFICIT OF 15.5 MILLION BARRELS HAS CREATED

While approximately 21 million barrels of oil per day passed through the Strait of Hormuz in the last quarter of 2025, approximately 3.3 million barrels of this flow continued during the crisis period.

According to the report, the oil supply-demand gap that needed to be replaced in the global system was calculated as approximately 15.5 million barrels per day, due to the increase in oil stocks of China and other countries before the crisis and the halt of these purchases.

Approximately 35 percent of this shortfall was covered by rerouting through alternative pipelines and increased production outside Hormuz.

Thanks to more intensive use of Saudi Arabia's East-West Crude Oil Pipeline and the United Arab Emirates' pipeline to Fujaira, an additional daily flow of approximately 4.7 million barrels of oil was brought to the market from outside the Strait of Hormuz.

Additional production from producers other than Hormuz, especially Brazil, Kazakhstan, the USA and Venezuela, contributed approximately 500 thousand barrels per day.

The use of oil stocks covered 20 percent of the deficit. Approximately 3.5 million barrels of oil per day were used from global stocks. Approximately 2.5 million barrels of this came from the coordinated stockpile use of International Energy Agency members, and approximately 1 million barrels came from China.

Approximately 45 percent of the remaining amount was offset by a decrease in oil consumption of 6.8 million barrels per day.
