Today I was researching on earlier similar economic shocks as current Trump Circus. I found 1971, Nixon Shock was equally big when he abolished Dollar linkage to Gold ie 35 USD to one Ounce of Gold. This rate was fixed since 1944 Bretton Wood Agreement.

Then to counter US deficits, he allowed dollar to get devalued against German mark as well as Japanese Yen. USD devalued from 3.51 to 1.6 in just 10 years.
It devalued similar against Japanese yen from 360 to 227 till 1980 and to 95 yen in 1995.

Japan has coped up 300 percent currency appreciation in 25 years because of innovation and JIT.

I need to learn more about Macro economics and politics of 1970 era to reach some insights but Now imagine if USD devalues against INR by just 30 percent not 300 percent in next 5 years ie 60 rupees to one USD, what will happen to Indian Exports and especially to Indian IT industry.

Just a question to ponder to design our future.
