2008: rice export bans amplify a thin-market crisis

India banned non-basmati rice exports (partial ban Oct 2007; outright ban effective 1 Apr 2008). Vietnam halted commercial rice sales for March–April 2008, then extended the halt through June despite a bumper harvest. Egypt, Cambodia, Brazil and Indonesia followed with bans or curbs. With only about 30 million tonnes of rice traded worldwide each year — and thin tradable stocks, demand pressure, input costs, and importer stock-building already priming the market — a handful of exporters closing the tap spooked importers — the Philippines and Bangladesh scrambled to build stocks — and Thailand floated the idea of an OPEC-for-rice, which scared markets further.

NPR (10 Apr 2008): 'Demand is up, production is down, and major exporters like Vietnam and India are limiting overseas shipments of rice. The shortage is creating concern about the possibility of social unrest.' FAO (12 May 2008): international rice prices had 'soared by 76 per cent between December 2007 and April 2008' and would remain 'extremely firm, at least until the third quarter of 2008, unless restrictions on exports are eased.'

  Record harvests arrived, panic ebbed — more than a quarter of the price came back off by year-end.

USDA ERS, writing in September 2008 while prices were still falling, found the surge was 'not due to poor harvests, a surge in demand, or a tight global supply situation': 2007-08 production was the largest on record and ending stocks actually rose. That was the contemporary diagnosis; the fuller read is that export restrictions amplified underlying pressure from thin tradable stocks, demand, input costs, and importer stock-building — and the honest uncertainty was how long the bans would last. India's stayed through 2009.

The bans were real and they did move prices — but they amplified a crisis already underway: tradable stocks were thin, demand and input costs were running hot, and importers were scrambling to build stocks. Record 2007–08 harvests and rising ending stocks did not stop the spike, because the panic was about who could access the thin traded margin. Once harvests arrived and the scramble eased, prices fell more than a quarter from the April peak (USDA ERS, Sep 2008).
