Jun 20, 2026 (Bloomberg) \u2013Ships can consider transiting the Strait of Hormuz<\/a> along the southern route at any time of day with their signals on, a key naval information group said, as energy traders and shipowners look for clues about how quickly and safely Hormuz traffic can return to normal.\u00a0<\/p>\n

There\u2019s no obligation to coordinate with the US navy when sailing through the strait along the coast of Oman, the Joint Maritime Information Center, which liaises between navies and merchant shipping, said in an\u00a0advisory<\/a>. That\u2019s in contrast to an update Iran published this week, which said vessels can only transit the waterway with\u00a0Tehran\u2019s permission.\u00a0<\/p>\n

One oil supertanker appeared to be transiting using the southern route with its satellite signal switched on early Saturday. Significant spoofing and jamming<\/a> in the area make it tricky to guarantee the veracity of such signals, however. Two Chinese fuel tankers also appeared to be leaving via the Iranian route.<\/p>\n

Traffic through Hormuz, which before the war handled a fifth of the world\u2019s oil, surged on Thursday after a peace deal between the US and Iran came into effect but eased off again the next day as uncertainty emerged over a safe opening of the strait. The unclogging of supply has the potential to unleash a wave of trapped barrels onto the oil market, and crude prices are now more than 35% lower than their peak at the height of the war.<\/p>\n

\u201cMariners are advised that they may transit the southern route day or night with their AIS on, radars radiating, running lights on, and normal use of VHF,\u201d JMIC said, referring to the automated identification system from transponders, and very high frequency radio communications. \u201cCoordination with NCAGS is not mandatory. Ships may transit the southern route without coordination.\u201d<\/p>\n

Ships should be aware of potential congestion, and the possibility of mines in the strait, JMIC said, adding that clearing operations are expected. Pakistan\u2019s hydrographic service warned that a\u00a0mine<\/a> was spotted near Oman on Friday, though the US navy has previously said that the southern route is free of mines.<\/p>\n

The JMIC\u2019s latest update comes after the US military encouraged vessels earlier this week to transit Hormuz \u201cdark,\u201d meaning that ships should turn their transponders off, according to an\u00a0advisory seen by Bloomberg News.\u00a0<\/p>\n

Though co-ordination with the US<\/a> isn\u2019t necessary to transit, the advisory said that ships should communicate with the American navy for information regarding safe transit routes.\u00a0<\/p>\n

The JMIC also now assesses the security threat level in Hormuz is \u201cmoderate,\u201d a notch lower than the \u201csubstantial\u201d level before the signing of the deal.<\/p>\n
