Gulf standoff shocks markets
Markets are treating the U.S.–Iran confrontation as a real threat to energy and shipping, pushing Brent above $100 a barrel and sending investors into the dollar as a safe haven. U.S. moves toward a blockade of Iranian ports are what's being priced in, and analysts warn that sustained disruption through the Strait of Hormuz — which handles roughly 10% of global trade — would force long reroutes around the Cape of Good Hope, lengthen transit times and raise freight and insurance costs.

Oil and currency markets are now trading the United States-Iran confrontation as a direct threat to Gulf energy exports and commercial shipping. (reuters.com) In early Asian trading on Monday, April 13, the dollar rose to its highest level in a week as investors moved into safe-haven assets after weekend talks between Washington and Tehran failed. Reuters reported that U.S. moves to begin a blockade of Iranian ports were a central driver of that shift. (reuters.com) Oil moved even faster. Brent crude rose above $100 a barrel and United States crude climbed above $104 after President Donald Trump said on Sunday, April 12, that the United States Navy would start blockading Iranian ports and shipping. (reuters.com) (cbsnews.com) The Strait of Hormuz is a narrow sea lane between Iran and Oman that carries about 20.9 million barrels a day of oil, or roughly one-fifth of global petroleum liquids consumption in the first half of 2025. The United States Energy Information Administration calls it the world’s most important oil transit chokepoint. (eia.gov) The same passage also carried about one-fifth of global liquefied natural gas trade in 2024, mostly from Qatar. That means any sustained disruption hits not only crude buyers, but also power markets and industrial fuel supply chains. (eia.gov) Shipping markets already have a recent model for what rerouting looks like. During the Red Sea crisis, the United Nations Conference on Trade and Development said ships avoided the Suez Canal and sailed around the Cape of Good Hope, extending voyage distances, transit times and operating costs. (unctad.org) United Nations trade data show the detour around southern Africa pushed up delays, fuel use and insurance costs, while arrivals around the Cape of Good Hope surged 89 percent. The agency said longer routes also lifted global vessel ton-mile demand by 3 percent and container ship demand by 12 percent. (unctad.org 1) (unctad.org 2) Washington says the pressure is aimed at Tehran’s shipping and exports, not at closing the waterway to all traffic. Reuters reported the U.S. military said the blockade would apply to vessels entering or leaving Iranian ports, while commercial traffic to non-Iranian ports would still be allowed. (reuters.com) (usatoday.com) Energy analysts are still pricing a wider risk: disruption, retaliation or miscalculation in a waterway with few easy substitutes. The Energy Information Administration said in an April 7 release that even limited Hormuz closures can force production shut-ins and fill storage quickly in exporting countries that depend on the route. (eia.gov) That is why traders are bidding up oil, buying dollars and watching shipping lanes as closely as battle lines. For now, the market signal is simple: the Gulf is being priced as a supply shock, not just a diplomatic crisis. (reuters.com) (eia.gov)
