Washington to announce new Iran sanctions as rial hits record low, Treasury Secretary nominee Bessent set to deliver update Monday

U.S. officials are preparing to announce a new round of sanctions against Iran Monday as the country’s currency, the rial, reached a record low, according to PBS NewsHour. The move, described as part of the administration’s effort to increase economic pressure on Tehran, comes against a backdrop of sustained U.S. restrictions and intensifying scrutiny of Iran-linked financial activity and other enabling networks.

PBS NewsHour said the announcement is expected to be delivered by Treasury Secretary nominee Scott Bessent as Washington finalizes the legal and regulatory steps needed to implement the package. The report framed the decision as an attempt to add further pressure on an economy already strained by previous U.S. sanctions, with additional consequences linked to enforcement actions including a U.S. naval blockade, which PBS said has contributed to the overall economic climate.

The sanctions decision arrives as Iran’s currency weakness accelerates. PBS reported that the rial’s decline to a record low Monday underscored the immediate economic stakes of Washington’s timeline, including how quickly markets respond to indicates of additional restrictions. Officials typically tie sanctions announcements to specific categories of conduct, target sectors, and outline compliance expectations for banks, traders, insurers, and other intermediaries.

While the PBS report did not provide details on which sectors or entities would be targeted in the new package, it characterized the overall approach as cumulative, with each step designed to make it harder for Iran to generate hard currency, conduct cross-border transactions, or access goods and services. In past sanctions regimes, packages often combine financial restrictions with controls related to shipping, procurement, and dealings with sanctioned parties, though specific elements of Monday’s new action were not spelled out in the report.

The expected announcement also raises questions about how U.S. enforcement and compliance mechanisms will apply in practice. U.S. sanctions authorities generally require banks and counterparties to screen transactions and institutions for prohibited links, and governments often publish licensing guidance for certain permitted activities. If sanctions expand, compliance teams may need to update due diligence processes quickly, with possible impacts for legitimate businesses that operate in regions where Iran-related transactions are already heavily scrutinized.

For Iran, the combination of currency pressure and tightened sanctions enforcement can affect household purchasing power and the broader cost of imports. For U.S. partners and maritime stakeholders, the report’s mention of a naval blockade points to the operational dimension of the policy, where interdictions and shipping restrictions can carry effects that extend beyond the targeted Iranian economy to regional trade routes.

Monday’s sanctions announcement is expected to be the central next step. After officials publish the final measures, affected entities and countries typically seek clarification on definitions, timelines, exemptions, and compliance standards. The PBS report suggested the new package is intended to continue a sustained campaign of economic pressure, with the rial’s record low acting as a measure of how closely developments in Washington track immediate conditions in Iran.
