The central bank of India announced concern about the fast growth in its currency's derivatives trading in the last three years. This prompted India's central bank to investigate foreign investing funds and have them prove that their investments would not speculated on the rupee alone.

The biggest jump of trade involving currency was experienced last June. This was the largest listed leap on the National Stock Exchange of India Ltd since January 2010. The futures and options trading involving the Indian rupee increased by 47% to a daily average INR387.7 billion.

India's rupee touched an unprecedented INR60.7650 per USD on June 26. On the same day, the Reserve Bank of India (RBI) asked overseas funds for proof that their individual accounts sought to limit currency risk on securities by means of using derivatives. The bank also inquired about the open positions of lenders that involved the rupee. Spokesperson for RBI did not immediately respond to an email sent outside of business hours in Mumbai.
