The Arab Spring cost $614 billion in lost growth to Arab countries, a new UN survey has found.

The report, the first of its kind by a major economic body, estimates that conflicts in the region between 2011 and 2015 led to a net loss of $613.8 billion in economic activity, equivalent to 6 per cent of the region's GDP.

To reach the figure, the UN's Economic and Social Commission for Western Asia (ESCWA) used growth projections made before 2011. The calculation includes direct and indirect effects of the conflicts, including refugee arrivals and falls in tourism.

The ESCWA also calculated that countries in conflict since 2011 and countries experiencing spill-over together have had a fiscal balance shortfall of $243.1 billion, $217.9 billion more than had been projected.

"The economic and political uncertainty that has characterised the Arab region in the wake of the 2011 transitions and upheaval continues to restrain the region’s prospects for growth, job creation and stability," the ESCWA says in the survey.
