Iran Warns Third Countries That Supporting New U.S. Sanctions Constitutes an Act of War

Iran’s top security official warned on August 24, 2026, that any nation participating in or backing new United States economic sanctions against Tehran will be treated as a hostile state, characterizing the enforcement mechanism as an act of war.

The warning, issued by Supreme National Security Council Secretary Mohsen Rezaei, follows an announcement by U.S. Treasury Secretary Scott Bessent detailing a sweeping financial offensive aimed at isolating Tehran. Rezaei stated that countries aligning with the U.S. pressure campaign would face direct retaliatory measures. He further reiterated threats that Iran could block oil exports through the Strait of Hormuz and the broader Persian Gulf if the economic restrictions continue to tighten.

The escalation broadens the scope of the bilateral dispute between Washington and Tehran, directly targeting third-party governments and international entities that cooperate with the enforcement of secondary sanctions.

U.S. Financial Offensive Unveiled

The exchange follows Treasury Secretary Scott Bessent's introduction of "Operation Economic Outcast" during a press conference in Washington. Described by U.S. officials as an "economic D-Day," the initiative targets five sectors of the Iranian economy, including digital assets, technology, gold, aviation, and shipping.

The Treasury Department also announced sanctions targeting roughly 60 entities, individuals, and vessels across multiple jurisdictions accused of enabling Iran to procure sensitive technology or market its oil. While the administration demanded that international partners sever commercial ties with Tehran, the Treasury stopped short of imposing immediate sweeping penalties on major trading nations, instead indicating that violators would face defined timelines to comply or risk being cut off from the U.S. dollar-based financial system.

Broader Regional Context

The latest round of economic pressure arrives nearly six months into an ongoing conflict between the United States and Iran that has heavily restricted commercial traffic and energy shipments through the Strait of Hormuz. With bilateral diplomatic channels largely at an impasse, both sides have increasingly relied on financial pressure and strategic leverage points in the Gulf to influence foreign policy outcomes.
