New US sanctions may target global shipping and finance, while Iran threatens to block all Gulf oil exports, escalating crude market risks.
The US is poised to announce its most stringent sanctions on Iran, potentially forcing allies to choose between compliance or secondary penalties. These measures could extend beyond direct trade to disrupt shipping, insurance, and financial intermediaries, tightening global oil logistics even without physical disruptions.
Iran’s security chief has threatened to halt all oil exports from the Persian Gulf, not just the Strait of Hormuz, marking a significant escalation. Markets have priced in partial disruptions, but a total blockade would exceed current expectations. Tehran also hinted at targeting US financial markets, adding volatility beyond energy infrastructure.
Crude benchmarks, tanker freight rates, and regional equities are expected to face heightened volatility ahead of Monday’s announcement. Downside risks dominate if the sanctions provoke immediate Iranian retaliation, amplifying supply concerns.
