Global oil prices top $91 a barrel after U.S. and Iran exchange fire for the first time in a month

The escalation marks the first direct exchange of fire between Washington and Tehran in a month, adding a fresh geopolitical premium to crude. Global benchmark prices have pushed above $91 a barrel as traders reassess supply risk in a region critical to global exports. The move is not just an energy story; it has quickly become a macro story.

The significance lies in timing. Every extra dollar in the price of oil now lands in a market that has suddenly rediscovered the possibility of another interest-rate hike. Higher energy costs feed into headline inflation, complicating the calculus for central banks, and for investors this shifts the focus from growth to the path of monetary policy.

What to watch is whether the conflict broadens and whether the price move holds, as well as how incoming inflation data and central bank commentary respond to rising energy costs. The situation remains fluid, and the market's reaction will depend on developments in the region as much as on economic data.
