Oil approaches $100 a barrel as Iran strikes widen in Persian Gulf

Brent crude pushed close to $100 a barrel in the session covered here, after Iran struck a U.S. military base in Jordan and hit shipping in the Gulf, according to wire reports. The moves follow earlier tanker strikes and mark an escalation traders had been watching for weeks. The jump matters because it raises the odds that a real supply disruption, not just a fear premium, starts showing up in physical oil markets. Gulf shipping lanes carry a large share of the world's seaborne crude, and any prolonged threat to tankers pushes up insurance costs and freight rates even before a single barrel is lost. What is unresolved is whether this is a peak in tension or the start of a longer conflict. Currency markets showed a related flight-to-safety move, with the yen holding near a seven-month high against the dollar as investors sought shelter.
