The Long-run Determinants of Indian Government Bond Yields

This paper investigates the long-term determinants of Indian government bonds' (IGB) nominal yields. It examines whether John Maynard Keynes's supposition that short-term interest rates are the key driver of long-term government bond yields holds over the long-run horizon, after controlling for various key economic factors such as inflationary pressure and measures of economic activity. It also appraises whether the government finance variable--the ratio of government debt to nominal income--has an adverse effect on government bond yields over a long-run horizon. The models estimated here show that in India, short-term interest rates are the key driver of long-term government bond yields over the long run. However, the ratio of government debt and nominal income does not have any discernible adverse effect on yields over a long-run horizon. These findings will help policymakers in India (and elsewhere) to use information on the current trend in short-term interest rates, the federal fiscal balance, and other key macro variables to form their long-term outlook on IGB yields, and to understand the implications of the government's fiscal stance on the government bond market.
