Difficulty attracting foreign investors to India's bond market. After adjusting for consumer inflation India's three month Treasury bill pays a negative 2.3%, according to Citi. Official foreign funds data for India shows as of Dec. 16, 2013, that foreigners used up only 32% of the quotas assigned to them in the bond market. If they were to use up the entire quota this would be $81 billion compared to the deficit for the year ending March of $50 billion. Foreign investors also have to deal with the risk that the currency could depreciate as in the summer of 2013, for which they need higher interest rates. The RBI increased interest rates twice since Rajan's taking office in September 2013. During 5 months of 2013 foreigners made a net withdrawal of $12.9 billion.
