Depreciation of rupees against US dollars?

Answer 1

Well, this is not something that can be answered in a single sentence. But to give an overall picture without getting into the deeper details, the reason would be:

"Exchange Rate is nothing but the price of a Currency in the International Market. If the demand for the dollar is higher than its supply, the Rupee should depreciate. If it is the other way round, it should appreciate"

The Key reason for this would be the global economic scenario. The economic situation, world over is very volatile. People are worried about the safety of their investments. Because of risk aversion on the part of people, US Dollar regained its place as a Safe Haven. People still believe that the US Dollar is much safer than any other currency in the world and hence are accumulating the US Dollar. This effectively means that, the demand for the Dollar is going up which essentially means the price of other currencies (Exchange Rate) may be affected.
