Strait of Hormuz: Iran demands vessel approval, raises risk of shipping disruption

The Strait of Hormuz crisis escalated after Iran’s IRGC issued a radio warning to international shipping. It demanded mandatory authorization for any vessel transiting the Strait of Hormuz, saying ships attempting passage without permission would face destruction. The alert challenges a U.S.-brokered de-escalation plan that was expected to reopen the route after a short pause in U.S. military actions. Traders and shipping operators also point to on-the-ground signs: patrol aircraft operating in the Persian Gulf, commercial vessels remaining anchored outside the strait, and increased Iranian naval activity near key lanes. With the Strait of Hormuz moving about 21 million barrels per day, analysts say Iran is using disruption leverage in sanctions talks. Insurers and shipping firms are reassessing war-risk premiums and rerouting options, adding cost and time because pipelines have limits and detours via Suez or around the Cape are slower. Markets reacted quickly: Brent futures rose roughly 4.2%. For crypto traders, the key transmission is macro risk sentiment. Higher oil-price volatility can tighten liquidity and weaken correlations with risk assets—matching broader crypto weakness. Bitcoin extended losses near $65,730, Ether slipped below $1,980, and the overall crypto market value fell about 4% to around $2.35T, with the Crypto Fear & Greed Index in “extreme fear.” Focus over the next days on liquidity and how strongly crypto risk tracks energy and geopolitical escalation.
