On a stretch of water barely 33 kilometres wide at its narrowest point, the stakes could hardly be higher. The Strait of Hormuz, through which roughly a fifth of all globally traded oil passes, has become the site of a renewed series of attacks on commercial vessels — incidents that are accelerating a quiet but consequential diplomatic conversation between Tehran and Muscat about how energy flows might be redirected away from this perennial flashpoint. The attacks, whose precise attribution remains a matter of dispute among Western intelligence agencies, have sharpened anxiety in shipping markets from Singapore to Rotterdam. Insurance premiums for vessels transiting the strait have risen sharply, and several major carriers have already begun re-evaluating their routing options.

The incidents follow a pattern that analysts at the International Crisis Group have described as calibrated provocation — aggressive enough to signal leverage, restrained enough to stop short of outright war. What makes the current moment distinctive is the parallel track of diplomacy running alongside the violence. Iran and Oman — which has long served as a discreet back-channel between Tehran and the West — are understood to be in advanced discussions over a pipeline or overland corridor that would allow Iranian oil exports to bypass the strait entirely and reach Omani ports on the Arabian Sea. Such a route would reduce Iran's own vulnerability to a potential blockade, while offering Muscat a significant economic and geopolitical dividend.

The arrangement, if it materialises, could redraw the energy map of the broader Middle East.
