Emerging Asia exports further ride its downward trajectory in 3Q15

They weakened for the fourth straight quarter.

Fitch Ratings says Emerging Asia's exports weakened for the fourth straight quarter in 3Q15, underperforming other emerging regions in volume terms.

According to a release from Fitch Ratings, emerging Asian currencies have weakened less, on average, than those of other major emerging regions on a real trade-weighted basis, partly explaining the divergence.

Global trade growth has been weak since 2009, the release said. Part of the explanation likely lies in the flattening of the US trade deficit since 2013 - previous US recoveries saw the deficit carry on rising.

This is related to the shale oil revolution and to a shift in US savings behaviour, according to Fitch Ratings.
