NEW YORK, September 23 — The Strait of Hormuz, the narrow waterway that carries roughly a fifth of the world’s oil supply in normal times, remains the center of one of the worst maritime shipping disruptions in decades, six months after the United States and Israel went to war with Iran and the strait was closed. Traffic through the strait has dropped by 95 percent, according to reporting on the shipping disruption.
The waterway is about 33 kilometers (21 miles) wide at its narrowest point, bounded to the north by Iran and to the south by the United Arab Emirates and Oman’s Musandam Peninsula. Think of it like a single highway ramp serving an entire region’s export economy.
There is no fully adequate alternative route for most of the volumes that move through it, which is why the strait has no equal in global energy logistics.
Why this one waterway matters so much
The strait is the primary export route for Saudi Arabia, Iraq, Kuwait, Qatar, Bahrain, and the United Arab Emirates, as well as Iran itself. Qatar’s liquefied natural gas exports, among the largest in the world, also depend on it. When the strait closes, those flows do not simply shift to another lane.
Oil prices surged to nearly a six-week high amid a wave of strikes between the United States and Iran in the strait. More recently, prices dived on signs of diplomacy, after a rare meeting between Iran and its Persian Gulf neighbors renewed hope for a deal that could fully reopen the strait.
The diplomatic track runs through New York
United States and Iran officials are meeting in New York to discuss ending the war. That meeting is the current focus of efforts to resolve the closure. The crisis has reshaped global energy flows.
Asia suffered some of the worst economic fallout because the region is heavily reliant on Gulf oil and gas that normally flows through the strait, and it is now looking to store oil and gas closer to home. Saudi Arabia has been left hanging in its fight against an Iranian ally threatening crude’s other chokepoint, the Bab el-Mandeb Strait, which links the Red Sea to the Gulf of Aden and sits between Yemen and the Horn of Africa.
Refineries become the new bottleneck
Analysts at McKinsey & Company have framed the situation as a question of energy security beyond the Strait of Hormuz crisis. The Centre for Economic Policy Research has described the episode as the 2026 Hormuz shock and analyzed energy markets under chokepoint stress. The Wall Street Journal has reported that refineries are now the main chokepoint for global energy supplies, a shift that matters because even if crude can be rerouted, refining capacity cannot be relocated quickly.

The story is an energy industry story above all: it is about oil and gas flows, shipping, refining, storage, and the price signals that connect them. The core facts are these — the strait is 33 kilometers wide at its narrowest, roughly one fifth of world oil supply normally passes through it, traffic is down 95 percent six months into the war, and the diplomatic track now runs through a meeting in New York between United States and Iran officials.
The Bab el-Mandeb Strait remains the other vulnerable chokepoint under pressure. What to watch next: whether the New York talks produce a deal that could fully reopen the strait, and whether refinery capacity — the bottleneck that cannot be moved — keeps global energy supplies tight even if crude starts flowing again.
