US Tightens Iran Sanctions, Adds 60 Entities Amid Oil Market Turmoil

The U.S. Treasury Department on May 19 sanctioned 12 individuals and 48 corporate entities and vessels connected to Iran's energy trade, escalating its "extreme pressure" campaign as negotiations to end the wider conflict with Tehran show little progress.

"Every additional dollar the Kremlin earns from this licence helps Putin finance his illegal war against Ukraine and kill innocent Ukrainians," Democratic senators Jeanne Shaheen and Elizabeth Warren said in a statement, criticizing a separate waiver on Russian oil that complicates the U.S. stance.

The new sanctions target 19 transport vessels, including oil and chemical tankers, and 29 trade and shipping companies, among them the Amin Exchange. The move comes as Brent crude, the international benchmark, trades near $109 per barrel. The ongoing Iranian blockade of the Strait of Hormuz—a chokepoint for over 20 percent of global oil—and a counter-blockade by the U.S. continue to disrupt global supply chains and elevate energy prices.

The latest sanctions aim to cripple Iran's primary revenue source but risk further tightening a global oil market already strained by the conflict that began in late February. With Iran demanding the full release of frozen assets and insisting on its "non-negotiable" right to nuclear enrichment, the move complicates fragile, Pakistan-mediated negotiations and increases the risk of further escalation in the Persian Gulf.

A Two-Front Economic War

The Treasury's action against Iranian entities comes just days after it extended a sanctions waiver for Russian seaborne oil, a move intended to "stabilize the physical crude market," according to Treasury Secretary Scott Bessent. This dual approach highlights the difficult position of the Trump administration as it attempts to punish adversaries without causing a spike in domestic gasoline prices. The Russian waiver has been criticized by Democratic senators as an "indefensible gift" to Vladimir Putin.

The sanctions against Iran are more direct, adding the entities to the Office of Foreign Assets Control's (OFAC) Specially Designated Nationals (SDN) list, effectively cutting them off from the U.S. financial system. This action is part of a broader strategy to force Tehran back to the negotiating table on terms acceptable to Washington.

Stalled Negotiations and Hardline Stances

Despite talk of potential deals, both sides remain far apart. President Trump has stated he is giving Iran a "limited period of time" to make a deal, while Iranian officials have warned that any new U.S. aggression will be met with a "stronger response."

Tehran's peace proposals have included demands for a complete withdrawal of U.S. forces from the region, reparations for war damages, and the lifting of all sanctions. U.S. officials have reportedly countered with proposals for a 20-year ban on uranium enrichment, which Iran has rejected. The cost of the 80-day conflict has already exceeded $85 billion for the United States, according to estimates from Iran's Fars news agency.

India, a major importer of Russian crude, has stated it will continue its purchases regardless of waivers, prioritizing its energy security. This underscores the challenge the U.S. faces in enforcing a global consensus on sanctions, particularly when energy markets are volatile.
