Oil and gas shipping along a U.S.-protected corridor in the Strait of Hormuz showed signs of recovering Sunday, a day after a batch of vessels performed unexplained U-turns and detours in the vital energy corridor.

Six oil and gas freighters were observed navigating on a route that cleaves close to Oman¡¯s coast. Those are only what¡¯s observable, with many ships known to sail through with their transponders off to avoid digital detection. Western navies continue to say that, while traffic continues, the threat risk is ¡°substantial¡± and that the center of the strait has been mined. Two other small tankers exited the Persian Gulf by sailing closer to Iran.

The oil market is fixated on what¡¯s moving through Hormuz and how, a task that¡¯s become tougher because of ships trying to avoid the attention of Iran¡¯s military as they come and go. Over Friday and Saturday, at least eight vessels were seen U-turning as they sailed through along the Omani route. Four of them subsequently went on to sail northward toward the Iranian route, and exited the strait.
