CIR Afternoon Update — April 17, 2026
Crude oil prices suffered one of their steepest single-session drops in years on Friday afternoon as Iran's announcement that the Strait of Hormuz is open to commercial shipping triggered a massive wave of long-side liquidation across energy markets.
Hormuz Declared Open — WTI Crashes Nearly 10%
According to OilPrice.com, Iran's Foreign Minister Abbas Araghchi announced Friday that the Strait of Hormuz is "completely open" to commercial shipping for the duration of the US-Iran ceasefire. The declaration drew an immediate response from President Trump, who acknowledged the opening on Truth Social. WTI crude fell approximately 9.6% on the session to $85.57/bbl, while Brent Crude declined 7.4% to $92.03/bbl — reflecting the market's rapid reassessment of the geopolitical risk premium that had been built into crude prices since the US-Israel strikes on Iran in late February.
Tankers Begin Moving, But Questions Remain
According to OilPrice.com citing Bloomberg vessel tracking data, at least eight crude carriers began advancing toward the Hormuz chokepoint within hours of the announcement. Five vessels that had been idling north of Dubai moved first, followed by three more positioned roughly 70 miles west. A Pakistan-flagged Aframax tanker — the Shalamar — became the first vessel to clear the Strait with crude cargo since the blockade began. Despite the early signs of movement, Iran has not offered all tankers a blanket green light, with state-linked media floating the possibility of restricting passage for ships tied to "hostile" countries.
Significant Caveats Remain
According to OilPrice.com, the US naval blockade on Iranian ports remains in effect. Hundreds of tankers remain stranded across the Persian Gulf, and major ship owners are taking a wait-and-see approach. Analysts note that even if the passage holds, the backlog of vessels will take considerable time to clear, and Middle East producers face disrupted logistics and output that analysts suggest could take up to two years to fully recover.
