What is the adequate level of forex of any country? What are the adequacy indicators used? -

I am not too sure abt the levels// it depends on various parameters like FDI, balance of payments and trade deficit/surplus, the external borrowings.. It is usually measured in the number of days/weeks months worth of exports that can be paid by the reserves. It is like the savings of an individual - if your income stop, how many months can you survive/ pay your expenses.
