A massive supply shock is hitting the energy market from two directions. The US is blocking Iranian oil sales while simultaneously Russia is banning diesel exports, squeezing global supply and sending oil prices surging.

## Idea

The US military strikes on Iran and the revocation of their oil sale waivers have instantly removed a major source of global supply, pushing oil prices up over 5% in a single day. At the exact same time, Russia announced a ban on diesel exports following Ukrainian attacks on their refineries, tightening the market even further. This one-two punch creates a severe supply squeeze. Oil majors like Chevron were already seeing heavy premarket activity, and as this geopolitical tension shows no signs of cooling, these companies are perfectly positioned to capture the sudden spike in energy prices.
