The United States has announced a fresh round of sanctions targeting Iran’s oil industry, intensifying economic pressure on Tehran amid ongoing tensions linked to the closure of the Strait of Hormuz in the Middle East conflict.
The latest measures, unveiled by the U.S. Department of the Treasury, focus on more than two dozen individuals, companies, and vessels allegedly involved in Iran’s oil transportation network. The move marks a significant escalation in Washington’s efforts to disrupt what it describes as illicit oil trading operations tied to the Iranian regime.
In a statement, the Treasury’s Office of Foreign Assets Control (OFAC) said the sanctions specifically target a network linked to Mohammad Hossein Shamkhani, identified as a key figure in Iran’s oil shipping operations. He is the son of the late Ali Shamkhani, a senior Iranian security official.
According to the U.S. authorities, the network has been instrumental in facilitating the movement of Iranian oil through covert channels, enabling Tehran to bypass existing sanctions and generate revenue despite international restrictions.
Announcing the decision, U.S. Treasury Secretary Scott Bessent said the measures were part of a broader strategy to intensify economic pressure on Iran’s leadership and disrupt its financial networks.
“Treasury is moving aggressively by targeting regime elites that attempt to profit at the expense of the Iranian people,” Bessent stated. “Under President Donald Trump’s leadership, we will continue to cut off Iran’s illicit smuggling operations and networks linked to destabilising activities.”
He also issued a warning to global financial institutions, stressing that the United States is prepared to deploy all available tools, including secondary sanctions, against entities that continue to support Iran’s oil trade or facilitate transactions linked to it.
The announcement comes shortly after Washington allowed a temporary easing of restrictions on Iranian oil shipments at sea. The 30-day waiver, granted on March 20, was intended to ease pressure on global energy markets affected by the ongoing conflict in the region.
During the waiver period, officials estimate that approximately 140 million barrels of Iranian oil entered international markets, helping to stabilise supply amid disruptions caused by the crisis.
However, Bessent confirmed that the waiver, which is set to expire on April 19, will not be renewed, signaling a return to stricter enforcement of sanctions.
In addition to targeting Iran’s oil logistics network, the United States has also warned countries and companies against purchasing Iranian crude. U.S. officials indicated that buyers could face secondary sanctions if they continue such transactions.
“We have made it clear to countries that if you are buying Iranian oil or holding Iranian funds in your financial systems, we are prepared to act,” Bessent told reporters at the White House.
He added that Washington expects major importers, including China, to reconsider their purchases of Iranian oil in light of the renewed enforcement measures.
The U.S. State Department also weighed in, stating that the sanctions are part of a broader effort to significantly reduce Iran’s revenue streams, particularly at a time when tensions in the region remain high.
Officials accused Tehran of attempting to “hold the Strait of Hormuz hostage” by maintaining its closure, a move that has disrupted one of the world’s most critical النفط transit routes. The strait serves as a vital corridor for global oil shipments, and any prolonged disruption has far-reaching implications for international energy markets.
By targeting key players in Iran’s oil export infrastructure, Washington aims to curtail the country’s ability to finance its activities and exert pressure for a change in behavior.
Analysts say the renewed sanctions could further strain global oil supply chains, especially if enforcement measures significantly reduce the volume of Iranian crude reaching international markets. They also warn of potential geopolitical fallout, as affected countries weigh the risks of compliance against their energy needs.
For Iran, the tightening of sanctions represents another challenge in navigating economic constraints amid escalating regional tensions. For the United States, it signals a continued reliance on economic tools to pursue strategic objectives in the Middle East.
As the situation unfolds, global markets and diplomatic actors alike will be closely watching the impact of the new sanctions and the broader implications for stability in the region.
