Donald Trump's war on Iran could cause UK food prices to surge due to the soaring cost of fuel and fertiliser as the Strait of Hormuz – the narrow sea passage south of Iran – remains effectively impassable.
The blockade on fossil fuels through the strait is driving a spike in the cost of nitrogen and phosphate fertilisers – used for growing cereals and vegetables – and means farms now face a twin threat of higher fuel prices for machinery as well as for fertiliser as the conflict in Iran disrupts global supply chains.
