Maritime traffic through the Strait of Hormuz declined sharply this week, with daily transits falling to just seven vessels on Thursday, half the volume recorded the day before, Belgian shipping analytics firm Kpler said in a social media update on Friday.
Of the seven vessels, four were outbound from the Persian Gulf and three inbound. Three of the ships were identified as having links to Iran, Kpler noted.
Meanwhile, the U.S. Department of Treasury warned Friday that any shippers paying tolls to Iran for passage through the strategic waterway are at risk of punitive sanctions.
The Office of Foreign Assets Control (OFAC) under the department said the United States is aware of "Iranian threats to shipping" and demands for payments to receive safe passage through the strait, and the demands may include several payment options, including fiat currency, digital assets, offsets, informal swaps, or nominally charitable donations made to the Iranian Red Crescent Society.
"OFAC is issuing this alert to warn U.S. and non-U.S. persons about the sanctions risks of making these payments to, or soliciting guarantees from, the Iranian regime for safe passage," an OFAC advisory said. "These risks exist regardless of payment method."
The Strait of Hormuz handles roughly 20 percent of the world's seaborne oil flows. Iran tightened its grip on the vital waterway after Israel and the United States launched their joint strikes on Iran on Feb. 28. The U.S. imposed a naval blockade targeting ships going to and from Iran.
