One more reason for the fall of the rupee, as propounded by some economists, is the overseas non-deliverable forward (NDF) market that is not sanctioned by the Reserve Bank of India.
An NDF is a non-deliverable forward contract where financial institutions buy forward dollars (that is, they book dollars now for delivery at a predetermined future date) in the Indian market and at the same time sell a similar amount of dollars in an overseas market -- or vice-versa -- so that on the delivery date they make a profit or loss, which is the difference between both the rates.
