Countries of Asia and the former Soviet Union are the most vulnerable zones to the depreciations of ruble and yuan, Bloomberg reports.

“While Azerbaijan and Georgia have devalued their exchange rates over the past year, others including Armenia, Tajikistan, Moldova, Mongolia and Nigeria remain at risk,” Bloomberg experts say.

Kazakhstan has already allowed the tenge to drop, and Vietnam marked down the dong for the third time this year after the yuan’s decline last week.

According to expert Ilan Solot, the pressure is increasing, especially for those who are commodity exporters and those linked by trade with Russia.
