I made reference of these countries and their currencies against the USD, from year 2000 to their recent years high, we could see theses currencies have been depreciating drastically. These are just a few, there are many more, their currencies has also been depreciating over the years.
A weak currency brings inflation. This does not help when US Fed started to rise it's interest since December 2015, these currencies has weaken even further. From the recent Fed's announcement, they are determine to have more hikes.
