World's poorest countries rocked by commodity slump and strong dollar

Jubilee Debt Campaign warns that developing countries are struggling to make debt payments as revenues deteriorate

The collapse in global commodity prices and a stronger US dollar have depleted the public coffers of some of the world's poorest countries and will leave them as much as $61bn (43bn) worse off this year, a report has warned.

The Jubilee Debt Campaign said that countries that relied on exports of commodities such as metals and oil had seen government revenues hit by a global markets rout last year that knocked the prices of crude oil, iron ore, copper and other raw materials to multi-year lows.
