Some governments have responded to alarms about possible COVID-19-related food shortages much as consumers would: By trying to hoard food. A number of countries have limited exports of key staple food commodities to protect domestic supplies.

They conclude that international rice markets are particularly sensitive to such restrictions by large exporters—modeling shows they could significantly boost global prices and push millions of poor rice consumers into hunger.
