The US has sanctioned Iran’s Persian Gulf Strait Authority, which manages Hormuz passage requests, with Treasury Secretary Bessent saying the action targets Iranian tolls and maximum pressure on Tehran continues.

Summary:
Sources: US Treasury Department Office of Foreign Assets Control SDN list; Treasury Secretary Scott Bessent, 28 May 2026
- The US Treasury added the Persian Gulf Strait Authority to its Specially Designated Nationals list via the Office of Foreign Assets Control
- The Persian Gulf Strait Authority is the body Iran established to manage passage requests through the Strait of Hormuz
- Treasury Secretary Bessent said the action specifically targets Iran’s Hormuz toll regime and that the Treasury is maintaining maximum pressure on Iran
- Iran closed the Strait of Hormuz after the US and Israel launched military operations against Iran on February 28
- The Persian Gulf Strait Authority published a map last week reaffirming Tehran’s claims to a wide stretch of water on either side of the chokepoint
- The Strait of Hormuz carries approximately one fifth of global oil supply
Treasury Secretary Scott Bessent said the United States is maintaining maximum pressure on Iran as Washington sanctioned the Persian Gulf Strait Authority, the body Tehran established to manage passage requests through the Strait of Hormuz and collect tolls from vessels seeking to transit the waterway.
The designation was made by the Treasury Department’s Office of Foreign Assets Control, which added the authority to its Specially Designated Nationals list on Wednesday. The SDN list, which runs to thousands of named individuals and entities, carries sweeping consequences: any person or organisation subject to US jurisdiction is prohibited from dealing with a listed party, and foreign entities risk secondary sanctions exposure if they engage with designated bodies.
Bessent was direct about the intent. The action targets Iran’s Hormuz toll regime, the mechanism by which Tehran has sought to monetise and formalise its claim to authority over one of the world’s most critical energy chokepoints. By sanctioning the administrative body that processes those passage requests, Washington is making clear it regards any compliance with Iranian toll requirements as a sanctionable act, raising the legal risk for shipping companies, insurers, and flag states operating in the region.
The Strait of Hormuz has been closed to normal commercial traffic since Iran shut it following the outbreak of hostilities on February 28, when the United States and Israel launched military operations against Iran. The strait is the conduit for approximately one fifth of the global oil supply, and its closure has been a primary driver of the energy price pressures that central banks from Washington to Frankfurt to Seoul have spent this week describing as a significant inflation risk.
The Persian Gulf Strait Authority had signalled its intentions publicly only last week, publishing a map reaffirming Tehran’s claims to a wide stretch of water on either side of the chokepoint, a move that drew immediate international attention and set the stage for Wednesday’s sanctions designation.
The action sits alongside a broader maximum pressure campaign that has operated across financial, diplomatic, and military tracks throughout the conflict. Earlier on Wednesday, US forces struck a site near Bandar Abbas and intercepted Iranian drones in an incident whose accounts from the two sides contradicted each other almost entirely. The Iranian parliament’s national security committee earlier restated Tehran’s four non-negotiable red lines, including authority over the strait, as unchanged. The SDN designation of the body administering that authority makes the US position on that claim equally clear.

Sanctioning the body Iran set up to manage Hormuz passage requests is a direct challenge to Tehran’s toll regime and its broader claim to authority over the strait. The move raises the legal and operational risk for any entity that engages with the Persian Gulf Strait Authority, potentially chilling even nominal compliance with Iranian passage requirements. For oil markets, the designation reinforces that the US has no intention of legitimising Iranian control over the chokepoint, keeping the transit risk premium intact. Combined with Wednesday night’s duelling accounts of the Bandar Abbas drone incident, the sanctions action signals that the maximum pressure framework is being applied across diplomatic, financial, and military tracks simultaneously.

Next Move Markets desk view
For active traders, this brief should be read through the lens of energy markets rather than as a standalone headline. The key question is whether the theme behind US sanctions Iran’s Hormuz toll body as Bessent vows maximum pressure on Tehran can influence positioning beyond the first reaction. That means watching supply headlines, inventory data, OPEC policy, transport routes and geopolitical risk together, not in isolation.
A richer trading read comes from separating the catalyst from confirmation. The catalyst explains why markets are paying attention; confirmation comes from price action, liquidity and cross-asset behavior after the headline is digested. If those signals do not align, traders should treat the move as fragile and keep risk tighter.
What traders should watch next
- Whether the headline changes physical supply expectations or only short-term sentiment.
- How Brent and WTI react around recent technical ranges after the first volatility spike.
- Inventory data, OPEC communication and shipping-route risk that can confirm the theme.
- Currency moves and global growth expectations that may offset energy-specific catalysts.
Risk context
This article is a market-intelligence brief, not a trade recommendation. Before acting on the theme, traders should define invalidation, position size and the time horizon of the setup. The same headline can support a short-term reaction and still fail as a multi-session trend if liquidity, policy expectations or broader sentiment move the other way.
Scenario map
The base case is that traders keep this theme on the radar while waiting for confirmation from supply headlines, inventory data, OPEC policy, transport routes and geopolitical risk. A stronger continuation scenario requires follow-through after the first reaction, preferably with related assets moving in the same direction. A failure scenario develops if the headline is quickly absorbed, volatility fades and price returns inside the previous range.
For energy markets, the most useful approach is to compare the article theme with live market behavior. If the market confirms the narrative, pullbacks can become more constructive. If the market rejects it, the headline becomes background noise rather than a trading driver.
Execution discipline
- Define the level first: traders should know where the idea is invalidated before thinking about upside or downside.
- Separate news from setup: US sanctions Iran’s Hormuz toll body as Bessent vows maximum pressure on Tehran may explain attention, but entry quality still depends on timing, liquidity and risk/reward.
- Watch confirmation: a clean move usually appears across related markets, not only in one isolated instrument.
- Control exposure: if volatility expands, smaller position sizing can be more professional than chasing the headline.
Next Move Markets treats this kind of brief as a starting point for preparation: identify the driver, map the scenarios, then wait for the market to prove which path is actually being priced.
