Saudi Aramco chief executive Amin Nasser warned each week the Strait of Hormuz stays shut could shave roughly 100 million barrels from global oil supply, and could push Brent crude above $90 a barrel. Speaking on company’s earnings call, he said current crisis has already erased about a billion barrels of deliveries, although some flow has been rerouted via alternative ports and strategic reserves.

Nasser added the shock represents the largest energy‑supply disruption since records began, a claim underscored by Aramco’s 25% rise in quarterly net profit. The Iranian‑backed conflict has choked a route that handled roughly 20% of world oil and gas trade, prompting buyers to tap U.S. strategic petroleum reserves and seek longer‑haul tanker routes, in the near term.

If the strait remains closed for several more weeks, analysts expect full market normalization not until 2027, extending price volatility and pressuring refiners dependent on Middle‑East feedstocks. Investors will watch how alternative logistics and reserve releases mitigate the shortfall, but the prolonged bottleneck could reshape trade patterns and reinforce the strategic value of diversified export corridors for global trade.
