Iran War Disrupts Global Energy Supply, Raising Oil Prices and Straining Strategic Reserves
By Drooid · · How we work
Escalating Attacks on Key Shipping Chokepoints
Since the February 28 U.S.–Israel offensive against Iran began, attacks on vessels transiting the Strait of Hormuz have intensified. Maritime-security sources recorded at least 12 assaults on oil, LNG and LPG tankers during the week of September 28-October 5, the highest weekly total since the war’s outset. The United Nations International Maritime Organization logged nine incidents for the same period. Pressure has also mounted on the Bab al-Mandeb strait after Houthi forces seized ports in Yemen, forcing some shipments onto longer routes around Africa.
War’s Expansion and Energy-Market Shock
The conflict has spread to Yemen’s Houthi rebels, whose missile strikes on Saudi airports and Red-Sea facilities have further constrained maritime traffic. The 25th World Petroleum Council Energy Congress opened in Riyadh amid the turmoil, while the International Energy Forum—co-hosted by Italy (via videolink) and Nigeria—convened to address the fallout. The United States and Israel’s campaign, coupled with Iranian retaliation, has prompted governments to reassess energy-security strategies worldwide.
Data & Statistics
- Fossil fuels provide ? 81 % of global energy; oil 31.4 %, coal 25.9 %, natural gas 23.5 %.
- Before the war, the Strait of Hormuz carried about 20 % of global oil and gas shipments.
- Eritrea and Madagascar source ? 90 % of their oil from the Middle East; Pakistan 78 %, Japan 77 %, Kenya 77 %.
- South Korea obtains 31 % of its gas from the region, followed by India 29 %, Pakistan 27 %, Taiwan 26 %.
- Saudi Aramco’s Amin Nasser estimates < 6 billion barrels of commercial stocks remain, most not readily deployable.
- The International Energy Agency released a record 400 million barrels in March and plans an additional 100 million barrels of crude and diesel.
- U.S. Strategic Petroleum Reserve levels are at their lowest since 1982; China holds 1.4 billion barrels, the United States 413 million, Japan 263 million.
Official Statements & Responses
- Saudi Arabia’s Ministry of Energy confirmed the launch of the World Petroleum Council Energy Congress in Riyadh, emphasizing coordination of market responses.
- U.S. Secretary of State Marco Rubio asserted that oil flows through the strait are “close to normal levels,” despite ongoing attacks.
- The International Energy Agency announced readiness to release further oil from member reserves, prioritising diesel.
- The G7, in coordination with the IEA, agreed to immediately release 100 million barrels of diesel and crude to mitigate market volatility.
Conflicting Reports & Gaps
- Attack counts differ: maritime-security sources cite 12 incidents for the week of September 28-October 5, while IMO records nine.
- Flow assessments conflict: U.S. officials claim near-normal oil movements, whereas independent trackers note a drop from ? 15 million bpd in mid-September to 4 million bpd in early October.
- Data on the exact volume of emergency reserves available for immediate release remain unclear, with industry leaders warning that much of the reported stock is not “practically available.”
Verbatim Quotes
- “That’s probably the first time we’ve really seen a major constriction of a chokepoint,” — Richard Matthews, Gibson Shipbrokers
- “Estimates suggest less than 6 billion barrels of commercial inventories remain today with the vast majority not practically available,” — Amin Nasser, Saudi Aramco
What’s Next
The International Energy Agency is preparing to release an additional 100 million barrels of crude and diesel in the coming weeks, while market watchers anticipate further price volatility as attacks on tankers continue and regional diplomatic efforts evolve.
