Top reasons why a common currency is a bad idea

When the Euro happened, there was widespread belief in the market that it was the way to go.  There were talks about a South Asian currency or even a South East Asian currency.  What was never thought about was how different countries developing at different pace, different societies and political situations could band about on a common currency.

A good article here mentions about the top 10 reasons why the Euro will fail.  You can supplement these theories to other economies too and see why the fundamental argument for a common currency is a non-starter.

1. One interest rate cannot be suitable for everyone

One size cannot fit all!
