The cash-flow mismatches of the government are largely managed through issuance of treasury bills, access to the WMA facility from the RBI and issuance of CMBs when in deficit and through auctions of its cash balance in market (through RBI) and buybacks of securities from market, when in surplus. The limits for WMA for the first quarter of the Financial Year 2017-18 (April 2017-June 2017) was fixed at Rs60,000 crore.
