@itsdhiraj , assuming that you a US person ( citizen / GreenCard / Resident ) and with tax home in the USA, your functional currency is considered to be US$ and unless you are a business entity , generally currency losses are not recognizable ( not even under casualty losses because it is not usually an unforeseen event ).
Please read 26 USC 988 where these are dealt with. With very low probability of success, one could argue that a CD for a fixed time, is a forward looking contract ( only because the contract was in a non-functional currency and the risk should have been known ).
Sorry I could not give you good news.
Is there more I can do for you ?
