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.
