Global maritime trade depends on fewer than a dozen narrow passages. These corridors, some barely a few kilometres wide, funnel the energy, raw materials, and manufactured goods that sustain the global economy. When one is disrupted, the effects cascade: rerouting absorbs fleet capacity, freight rates spike, insurance premiums rise, and delivery timelines stretch, all of which feed directly into consumer prices and corporate margins.
The Suez Canal and its southern approach through the Bab el-Mandeb Strait historically carry roughly 12% to 15% of global maritime commerce, including a significant share of Asia-to-Europe container traffic and energy flows. The Strait of Hormuz carried roughly 20 million barrels per day before the conflict, approximately one-fifth of global petroleum liquids consumption, more than a quarter of seaborne oil trade and around 15% of global LNG trade, according to World Bank and EIA data. The Panama Canal, while smaller in trade share by weight, is critical for trans-American energy and container flows, particularly to the US East Coast.
What makes the current environment particularly consequential is the simultaneity of stress. Multiple chokepoints are under pressure at the same time, from different causes: renewed conflict in the Red Sea, the closure of Hormuz formally announced by Iran on 4 March 2026, and climate-driven draft restrictions at Panama. This convergence narrows the rerouting options available to shipping operators and compounds the inflationary impact.
