In response to Operation Epic Fury, Tehran turned to asymmetric leverage, relying on its capacity to disrupt shipping through the Strait of Hormuz and drive up global oil prices.
Anticipating market volatility, the US Treasury issued a targeted sanctions waiver designed to stabilize oil markets while preserving financial pressure on Tehran.
Yet as the waiver framework evolved from an India-specific mechanism into a more generalized policy, it continued in practice to serve Indian refiners, redirecting sanctioned crude away from China and toward India.
The Russian test case
On March 5, Treasury issued a waiver allowing Indian refiners — IOC, BPCL, HPCL, and Reliance Industries — to purchase already-produced Russian crude cargoes that were on the water.
When Treasury expanded the waiver on March 12–13, Indian refiners remained the only significant buyers of the authorized Russian barrels. The expansion continued to apply only to cargoes already on the water, did not restore formal banking channels, and did not lift underlying sanctions.
