The Reserve Bank of India (RBI) has announced major changes to how banks will have to value state government bonds, with far-reaching implications for the bond market and for state and central finances. Currently, state government bonds are accounted for on banks’ books using a straightforward yield-to-maturity approach; all state government debt, irrespective of which state has issued it, is marked up at 25 basis points above the yield of the equivalent Union government security, or G-Sec. This enforced uniformity will soon end, to be replaced with a valuation that is more closely tied to observed market prices. This is relatively easy to do for those state government securities that are regularly traded; for those that are not, the RBI said that “the valuation shall be based on the state-specific weighted average spread over the yield of the central government securities of equivalent maturity, as observed at primary auctions”. More will be known about this mechanism when detailed guidelines are issued next week, but the implications of the shift are already clear.
