The IMF on Tuesday upgraded its eurozone growth forecast despite Brexit uncertainty, but warned that low inflation, heavy debt and an ageing population could hurt the economy's recovery down the road.

In its latest world outlook, the IMF said the eurozone would reach 2.1 percent expansion in 2017 and growth would then slow to a still healthy 1.9 percent in 2018. This was an improvement from the previous estimate of 1.9 percent for 2017 and 1.7 percent in 2018.
