The COVID-19 pandemic is increasingly a concern for developing countries. This column shows that most developing countries rely heavily on imports to meet their needs of medical supplies essential to combat COVID-19. Recently imposed export restrictions by leading producing countries could thus cause significant disruptions in supplies for developing countries and might further contribute to price increases of medical supplies. Taking multiplier effects into account, prices for medical supplies are estimated to rise by up to 23% on average. Tariffs and other restrictions to imports further impair the flow of critical products to developing countries.
