Oil pushed near $92 on Strait of Hormuz tension, lifting Exxon and moving about $500 billion in market value.
What happened
Tension around the Strait of Hormuz, the narrow sea lane that carries a large share of the world's oil, sent crude near $92 a barrel. Oil is up 6.4% over the past week. Exxon rose with it. The move touched roughly $500 billion of market value across energy names.
Why it matters
When oil traders fear a supply chokepoint, they bid up the price of every barrel already flowing, because the ones still coming might not arrive. That flows straight to oil producers like Exxon, who sell the same output for more. It also spreads out: gold is up 3.3% as buyers seek a safe place, while chip stocks are pulling back inside their uptrend. Oddly, defence stocks are fading, trailing the market by 2.8% over the week, so this looks like an oil-supply scare more than a broad war trade.
The case against
The overall market is slipping today even as its longer trend still reads constructive, and stress gauges read calm, not panic. Fear-driven oil spikes can reverse fast if the chokepoint stays open. If tankers keep moving through Hormuz, the premium in the price drains away and Exxon's gain goes with it.
What settles it
Whether oil holds its jump or slides back toward where it started the week. If the price gives up its gains, the Hormuz scare was noise, not a shift.
