The August deadline for talks between the US and Iran came and went, as expected, with no resolution to the conflict. At time of writing, both sides were exchanging tit for tat attacks on ships in the Strait of Hormuz, with Iran claiming that it would be instituting a new ‘exclusion zone’, and no sign of a diplomatic resolution in sight. With the flow of ammonia, urea and other commodities like oil, LNG and sulphur from the Gulf still slowed to a trickle, the summer of high prices and demand destruction looks set to extend well into autumn at least.
