Tanker traffic through the Strait of Hormuz fell in the past day to a two-month low, according to shipping data Monday, amid heightened safety worries after renewed strikes between the U.S. and Iran and attacks on ships.

Shipping industry sources said vessels were increasingly switching off their public AIS tracking transponders, making it difficult to ⁠determine the full number of ships crossing the waterway.

Based ⁠on available data, oil and gas tanker traffic fell to its lowest level since May 25, according to analysis from Kpler.

"Should the renewed escalation in the strait lead to another prolonged closure of ​Hormuz, the world will find itself in a much tougher spot," ship broker Gibson ​said ⁠in a report.

"With global inventories rapidly depleted in recent months, this is a recipe for much tighter supply, higher prices and significant downside risk for tanker markets."
