Escalation following Iranian attacks on ships and US personnel pushes crude higher and fuels inflation fears.
Published
The US launched new airstrikes on Iranian targets around the Strait of Hormuz on Tuesday, escalating tensions after Iranian attacks on commercial vessels and US military personnel. The strikes quash hopes that an exchange of fire over the weekend would not presage a wider renewal of hostilities in the Middle East.
Oil prices had already risen following the first exchange of direct attacks between the two nations. The latest escalation pushed crude higher still, adding to concerns about energy costs in an already strained global economy. Markets are closely monitoring the situation for further developments.
The conflict escalation also rippled through fixed-income markets, sending Treasury yields to their highest levels of the day. Investors fret that the renewed Middle East hostilities could trigger a new bout of inflation, complicating the Federal Reserve's policy path forward.
US Central Command announced the strikes following Iranian attacks on ships operating through the strategically vital Hormuz Strait, through which a significant portion of the world's oil supply passes. The market reaction reflects heightened uncertainty about supply disruptions in one of the world's most critical energy chokepoints.
