JMIC

On 7 July 2026, JMIC kept the strait of Hormuz at SEVERE, its highest threat level. Its advisory described continued mine risk and Iranian Revolutionary Guard attempts to hail vessels using automatic identification signals and divert them towards an Iranian-controlled northern corridor.

Two days later, tanker traffic had fallen to about two ships a day after three vessels were struck overnight. JMIC's role was to combine incident reports and issue a risk picture for commercial operators. It did not control the vessels, naval response or insurance market, but its published rating gave shipowners a common basis for assessing the route.

On 20 June 2026, a JMIC-linked advisory warned that the standard Strait of Hormuz traffic lanes might contain mines and identified a safer route through Omani coastal waters. US Central Command said 55 ships carrying 17 million barrels used that route that day.

The following day's traffic showed that commercial vessels could still cross despite Iran's closure declaration, because the route ran through adjacent Omani waters. For JMIC, the episode showed the practical value of combining military reporting with guidance that commercial crews could use. The centre supplied the warning and route assessment rather than directing individual voyages.
