However, state government debt may also be attractive for some of the wrong reasons. There are market imperfections and those imperfections could lead to potentially dangerous situations. In effect, there is an implicit sovereign guarantee for state government debt issued by any of the 29 states. Due to that, there is not much difference between state debt yields despite wide variations in state ratings. No Indian state has ever defaulted. It would be incumbent on the Centre (and the RBI) to ensure that no state ever does default, especially to foreign creditors. But against the backdrop of implicit guarantees, creditors are likely to look for the highest available yields, assuming that the default risk is effectively zero. Going purely by yields, the states with the worst financial policies are also likely to be the most attractive from an investor's viewpoint because the highest yield will be associated with the states that have the lowest ratings. Thus, it is possible that West Bengal (rated BBB-plus) could place larger quantities with FPIs than Gujarat (A-plus) because West Bengal will surely offer somewhat higher yields.
This factor - implicit sovereign guarantees for all - could in itself raise questions about the relevance of the rating system. It could lead to topsy-turvy situations with major misallocations. States raise debt for multiple reasons, of which only some are sensible. Many states, for example, subsidise power to consumers and raise debt to service the losses their electricity boards incur as a result. Some states are quite large and their gross domestic product could be equivalent to that of small countries. So the state government debt market could, in some senses, be considered analogous to the euro zone: states with widely different fiscal positions and economies of different sizes are unified in a single currency market. The Greece crisis points to the problems that can arise from distortions in such markets. Ways must be found to guide states towards greater fiscal responsibility. Unless the curbing of profligate expenditure goes hand in hand with this liberalisation, helpful access to more funding could lead to problems down the line.
