In 2021, Sri Lanka banned chemical fertiliser imports. Rice yields collapsed by a third or more in a single season. Tea production dropped to its lowest since 1995, costing $425 million in export revenue. Food inflation hit 94.9 percent. The country defaulted on $51 billion in external debt on April 12 2022, the first sovereign default in its history. Six point seven million people, 28 percent of the population, became food insecure. The president fled the country on July 9 as protesters occupied his residence. That crisis was caused by a policy decision. One man banned one input. This crisis is caused by a strait.

The Haber-Bosch process converts atmospheric nitrogen into ammonia, the feedstock for urea, the fertiliser that grows the rice that feeds South and Southeast Asia. The process requires natural gas. The gas that feeds the Haber-Bosch plants in Qatar, Saudi Arabia, and the UAE transited the Strait of Hormuz. The strait has been effectively closed for five weeks. Urea spot prices hit $687 per tonne on April 2, up from approximately $500 before the war. Southeast Asian granular urea reached $750. Bangladesh shut four of its five state urea factories on March 5 due to gas rationing. The gas that grows the food is trapped behind the same chokepoint as the gas that powers the economy.

The kharif planting season runs April through June. Seeds not planted in April do not produce rice in October. Fertiliser not applied at sowing does not improve yields at harvest. The FAO projects fertiliser prices averaging 15 to 20 percent higher in the first half of 2026. Commodity analysts project 15 to 20 percent kharif yield losses if the shortage extends through May, and 12 to 18 percent global food price rises by year-end. India says its stockpile is “comfortable.” That claim will be tested by June. The food crisis is not a forecast. It is a planting calendar colliding with a naval blockade.

Bangladesh imports 95 percent of its petroleum and shut four of five state urea plants within a week of the blockade. Pakistan’s textile mills are dark. Sri Lanka reactivated the same QR fuel rationing system it deployed during the 2022 collapse, the crisis that this one now threatens to repeat through a different mechanism. In 2022, the cause was a president who banned imports. In 2026, the cause is a strait that blocks them. The chemistry is identical. The nitrogen is absent. The rice will not grow. The only difference is that in 2022, the ban could be reversed. In 2026, the strait cannot be opened by executive order. It requires either a military operation or a negotiation with the organisation that privatised it.

Russia is filling the gap with crude oil, not fertiliser. India’s Russian crude imports surged 90 percent in March. China sits on reserves and resells LNG at a profit. Neither is shipping urea to Bangladesh. The world is redirecting hydrocarbons but not nitrogen. The molecule that powers the car and the molecule that grows the crop derive from the same feedstock, trapped behind the same waterway. The world is solving for the first and ignoring the second.

Sri Lanka’s 2022 default took eleven months from fertiliser ban to sovereign collapse. The Hormuz closure is five weeks old. The kharif window closes in June. The trajectory is the same. The velocity is faster. And the number of countries on the path is not one. It is twelve.
