The life-and-death oil battle around the Strait of Hormuz

A global choke point under siege

The Strait of Hormuz carries roughly 20% of the world’s oil — about 20 million barrels per day (bpd) out of a global consumption of roughly 100 million bpd. Since February 28, it has been reported that Iran moved to seal the waterway and roughly 16 million bpd of supply was removed from the market. The shortfall has been partly made up — an estimated 4 million bpd — via increased flows through Saudi east–west pipelines, an Emirati bypass pipeline and continued Iranian shipments. It has been reported that satellite-traffic analysis shows many tankers briefly “going dark” and slipping out of the Gulf; other tracking data reportedly indicate Iran exported at least 11.7 million barrels in the 12 days before full-scale hostilities, averaging about 1 million bpd, with much of that oil likely headed east.

Iran’s tactical and economic leverage

Iran has long sought to blunt a maritime choke by developing alternative export points. Kharg Island (哈尔格岛), the Persian Gulf’s main loading hub, has been rebuilt as a de facto “oil island” where crude is piped in and loaded onto tankers because Iran lacks many deepwater ports. It has been reported that the United States struck military targets on Kharg on March 14 but held fire on oil-loading infrastructure — a calibrated warning. Tehran’s public posture is stark: it has been reported that the Islamic Revolutionary Guard Corps (IRGC) receives roughly half of export-related profits, a revenue stream described by some analysts as a “lifeline,” and Tehran has vowed that attacks on its energy infrastructure will be met with immediate strikes on companies linked to the United States.

Winners, losers and China’s buffer

Who benefits? Commodity exporters such as Russia have been big beneficiaries of higher prices; the Financial Times estimated Moscow earned an extra $1.3–$1.9 billion in the conflict’s first 12 days. The US is a mixed case — a seller of energy but also a heavy consumer wrestling with inflation. Europe’s exposure is smaller than China’s in volume terms, but Europe pays structurally higher prices for alternative supplies. China’s dependence on Hormuz is substantial: roughly 6 million bpd of the Strait’s flows go to China, and the immediate closure would create a gap of about 5 million bpd against China’s import profile (about 11.55 million bpd). Beijing’s cushions are notable. It has been reported that China’s government-led strategic petroleum reserves total about 1.4 billion barrels — enough to cover current shortfalls for many months — and policy shifts (EV adoption, domestic renewables and pipeline imports, notably from Russia) have reduced China’s short-term sensitivity to seaborne disruptions.

Strategic ripple effects and the long view

This is not just an energy story. Sanctions, naval posturing and the potential for wider conflict are forcing sovereign wealth reallocations and infrastructure planning: Gulf funds may repatriate capital to rebuild, and proposals for overland pipelines or even canals are back on the table. Markets will watch both military moves and the slow structural responses — storage fills, new trade routes, and accelerated clean-energy deployment. Oil remains a literal life-and-death strategic asset. Who will pay the price; who will build the bypass; and how long can the world absorb a squeezed Hormuz? Those are the questions now shaping geopolitics and global trade.
