Iran on Friday said that the Strait of Hormuz is “completely open” for all commercial vessels. “In line with the ceasefire in Lebanon, the passage for all commercial vessels through the Strait of Hormuz is declared completely open for the remaining period of the ceasefire,” Foreign Minister Abbas Araghchi said in a post on X.

He said the passage of ships would need to be along the route that Iran’s Ports and Maritime Organisation had announced.

Confirming the development, US President Donald Trump said the Strait of Hormuz is now fully open. Trump on Thursday announced a 10-day ceasefire between Lebanon and Israel. He, however, said the US blockade of Iran “will remain in full force” until Tehran reaches a deal with Washington to end the war.

“The ​Strait of ⁠Hormuz is completely open and ready ‌for business and full passage, but the naval blockade will remain in full force and effect as ⁠it ⁠pertains to Iran, only, until such time ⁠as ‌our transaction ​with Iran is ‌100% complete,” he wrote on Truth Social ‌in ​all ​caps.

The US-Israeli attack on Iran, which started on February 28, has killed thousands ⁠of people and ⁠destabilised the Middle East. The conflict also effectively closed the Strait of Hormuz, through which ⁠a fifth ‌of the world’s oil and liquefied ​natural gas transits, threatening the worst oil ‌shock in history.

War Premium: Current Price vs Pre-War Baseline (~$70)

⚠ Despite today’s crash, Brent remains ~$19/barrel above pre-war levels. Markets are still pricing in residual war risk — peace is not yet fully priced in.

📍 Key Catalyst

Strait of Hormuz Fully Reopens

Iran declares the strategic waterway fully open. Oil tankers can now exit the Persian Gulf and reach global markets — the clearest signal yet that supply disruption fears are easing.

Trump: War “Should Be Ending Pretty Soon”

President Trump’s late-Thursday statement was his most optimistic assessment yet. Combined with the Hormuz reopening, it drove Wall Street to a third straight week of big gains from its late-March bottom.

⚠ Caution Flag

War Premium Still Embedded in Oil

Despite today’s 10%+ crash, Brent crude at $89.13 remains well above its pre-war level of ~$70. A $19/barrel war premium indicates financial markets are not yet fully confident the conflict is over.

📉 Inflation Relief

Treasury Yields Ease as Oil Falls

Falling oil prices are easing inflation pressure. The 10-year US Treasury yield dropped to 4.24% from 4.32% late Thursday — a meaningful move signalling reduced inflation expectations in bond markets.

Stocks and bond prices jumped, while oil and the dollar fell sharply after Iran’s announcement. Oil dropped as much as 10% to below $90 a barrel immediately after the news, while short-dated government bond yields tumbled as investors priced out the likelihood of near-term rate hikes, especially in Europe, and stocks surged.

The dollar, which has acted as a safe-haven since the start of the war in late February, fell sharply against the euro, pound and yen.

The International Monetary ‌Fund this week ​lowered its forecasts ​for global ​growth and warned the global economy risked tipping into recession if the conflict was ​prolonged.

Trump had said on Thursday that ⁠talks could happen as soon as this weekend, although that was looking increasingly unlikely by Friday afternoon, given the ‌logistics of ⁠assembling officials in the Pakistani capital, Islamabad, where the talks are expected to take place.
