Key Points
Brent crude surged past $100 per barrel, up 30% in July as tanker attacks escalate.
Iran, Houthis, and Ukraine target shipping in Hormuz, Red Sea, and Black Sea simultaneously.
65 vulnerable economies face $20 billion annual import cost rise and slower growth.
Western shipowners reroute vessels or sail with transponders off to avoid attacks.
Global oil supply faces a perfect storm. Attacks on tankers in the Strait of Hormuz, Red Sea, and Black Sea have sent Brent crude above $100 per barrel for the first time since May, a 30% jump in July alone. Iran, Yemen’s Houthis, and Ukraine are all targeting merchant vessels, collapsing the June ceasefire and forcing shipowners to reroute or sail with transponders off. The disruption threatens to push inflation higher across 65 vulnerable economies.
How the Strait of Hormuz became a war zone again
A US-Iran memorandum of understanding signed on June 17 briefly reopened the Strait of Hormuz and paused hostilities for 60 days. The deal collapsed on July 8 after renewed Iranian attacks on tankers. Iran has stepped up attacks this month to assert control over the corridor, which carries one-fifth of the world’s oil and gas. Ship traffic through Hormuz has plunged since the collapse. Dimitris Maniatis, CEO of maritime risk service Marisks, told CNBC: “After the collapse of the MOU, we have entered the worst phase of this conflict for merchant shipping.” At least 12 tankers have been struck this month in and around Hormuz, killing at least two seafarers.
Three shipping routes under fire simultaneously
The conflict has spread across three critical waterways. In the Red Sea, Yemen’s Houthi militants declared a maritime embargo against Saudi Arabia this week and fired on two Saudi tankers. Ukraine reports attacking more than 150 tankers and cargo ships in the Black Sea and Sea of Azov linked to Russia’s shadow fleet. The International Maritime Organization says 61 commercial ships have been attacked in the Persian Gulf, Strait of Hormuz, and Gulf of Oman since March 1, resulting in at least 17 deaths and dozens of injuries.
Oil prices break $100 as shipping routes collapse
Brent crude surged past $100 per barrel on Thursday, the highest level since May. Oil has jumped to about $87 per barrel, a one-month high, as the security situation deteriorated rapidly. Helima Croft, head of global commodity strategy at a major bank, told CNBC the oil market is now dealing with wars on multiple fronts. Western shipowners are now making plans to avoid the Bab el-Mandeb strait at the southern end of the Red Sea or to sail through it with transponders turned off. Some vessels are rerouting via longer, costlier paths to India and beyond.
Nearly 1 billion people face higher inflation and slower growth
The price spike threatens the world’s poorest economies. According to UNCTAD data, 65 of 75 vulnerable economies are highly exposed to oil price shocks. Import costs could rise by £20 billion per year globally, representing more than 5 percent of gross domestic product for some nations. Higher oil prices translate directly into higher inflation, tighter government budgets, and slower economic growth for countries that can least afford it. Nearly 1 billion people live in these vulnerable economies.
Final Thoughts
Oil supply disruptions across three war zones have pushed Brent above $100 per barrel, threatening global inflation and growth. For UK investors, energy stocks may benefit from higher prices, but broader economic weakness could pressure equity valuations. Monitor ceasefire negotiations closely.
