US Treasury Sanctions Iranian Strait Authority Over Hormuz Control

WASHINGTON — The U.S. Treasury Department announced sanctions Wednesday against the Persian Gulf Strait Authority, designating the Iranian entity for its role in controlling vessel transit through the strategically vital Strait of Hormuz.

The move, effective immediately, targets the authority’s operations and financial networks, marking a significant escalation in U.S. efforts to pressure Tehran over maritime security and regional influence. The Treasury Department stated the sanctions are intended to disrupt the authority’s ability to manage and profit from the passage of commercial shipping through the narrow waterway, which serves as a critical chokepoint for global energy supplies.

The Persian Gulf Strait Authority is responsible for overseeing navigation, safety, and toll collection for vessels transiting the Strait of Hormuz. The U.S. government contends that the authority’s control over the strait enables Iran to leverage maritime traffic for political and economic gain, including the potential to disrupt global trade flows.

Treasury officials emphasized that the sanctions will prohibit U.S. persons from engaging in transactions with the designated entity and will freeze any assets the authority holds within the United States. The designation also warns foreign financial institutions that facilitating transactions for the authority could expose them to secondary sanctions.

The Strait of Hormuz connects the Persian Gulf to the Gulf of Oman and the Arabian Sea. It is one of the world’s most important shipping lanes, with approximately 20 million barrels of oil passing through the strait daily. Any disruption to traffic in the waterway could have immediate and severe consequences for global energy markets.

Iran has long maintained that it has the right to regulate traffic through the strait, citing national security concerns and the need to protect its territorial waters. Tehran has previously warned that external interference in the region could lead to instability.

The sanctions come amid heightened tensions in the Middle East, where diplomatic relations between the United States and Iran remain strained. The U.S. has repeatedly called for the free and safe passage of commercial vessels through international waterways, arguing that Iran’s actions threaten global economic stability.

It remains unclear how Iran will respond to the new sanctions or whether the authority will alter its operations in the strait. The designation adds to a growing list of U.S. sanctions targeting Iranian entities involved in regional security and maritime activities. Analysts are watching closely to see if the measure will impact shipping insurance rates or prompt further diplomatic friction between Washington and Tehran.
