G20 meets are usually considered to be jamborees where there is a lot of discussion on how the world economy should behave and how countries should foster growth through consensus. At times, it would not be more than a repetition of the earlier summits. But the recent one had a specific purpose on an aspect that, prima facie, has not really dominated the economic space, but has covertly been playing in the background, i.e. exchange rates.

The dollar has been falling against the euro and this has been unnatural because the euro region is
