Crude Oil Plunges Nearly 5% as Hormuz Tankers Flow and Iran War Premium Evaporates (USO, BNO)

Crude oil prices fell sharply on Wednesday, extending a violent unwind of the war premium that had inflated barrels for months. Brent crude lost 4.33% to settle at $73.74 a barrel, while West Texas Intermediate (WTI) slid 3.92% to close at $70.34, with U.S. crude briefly dipping below the psychologically important $70 mark intraday. Both benchmarks notched their lowest settlements since before the U.S. and Israel launched military action against Iran in late February. The sell-off was driven by a powerful convergence of de-escalation signals. The decisive catalyst was the resumption of tanker transits through the Strait of Hormuz, the chokepoint through which roughly a fifth of global oil flows. Shipowners regained confidence to transit the passage following safety guarantees, and increasing vessel traffic eased the supply fears that had underpinned the rally. Adding to the bearish tone, President Trump signaled that the Strait would remain open without transit fees, removing another layer of risk pricing. Progress in U.S.-Iran peace negotiations compounded the move. A new U.S. sanctions waiver on Iranian crude purchases raised expectations that previously constrained Persian Gulf barrels could return to the global market, flooding traders with restored-supply scenarios. With Iran having halted offensive operations and the ceasefire holding, the immediate threat of a broader regional conflict — and the disruption to physical supply it implied — has receded sharply. The price action reflects a classic deflation of geopolitical risk premium. During the height of the conflict, fear of a Hormuz closure had pushed Brent well above $75-$80; with that tail risk fading, prices are reverting toward fundamentals. Analysts had flagged $70-$75 as the likely normalization range for both benchmarks once the ceasefire stabilized, and the market is now testing the lower end of that band. For equity investors, the move pressures energy producers and oilfield services names whose margins track the benchmark, while offering relief to refiners, airlines, and transportation-heavy sectors via lower input costs. Energy ETFs tied to crude futures, including the United States Oil Fund (USO) and United States Brent Oil Fund (BNO), moved lower in tandem with spot prices. The near-term risk skews bearish as long as Hormuz traffic normalizes and diplomatic momentum holds. However, the rapid drawdown leaves prices vulnerable to a sharp snap-back should the fragile ceasefire fracture or sanctions relief stall. For now, traders are pricing peace, and the path of least resistance for crude is lower.
