MUMBAI: The Reserve Bank of India has likely used part of the initial inflows from its foreign-currency deposit drive to unwind a portion of its massive foreign exchange forward book, economists said, helping the central bank reduce near-term obligations.The RBI's package of measures aimed at supporting the rupee attracted more than $20 billion as of July 17, with more than ‌four-fifths coming from ⁠foreign ⁠currency non-resident (FCNR) deposits mobilised by banks.Also Read: RBI plans unified code for foreign investment in equity instrumentsSince these dollars are swapped with the RBI for rupees, they would ​typically be expected to boost India's foreign-exchange reserves.

However, reserves rose only by about $3 billion ​between the introduction of the measures and July 10, the latest date for which reserve data is available.The central bank likely used part of the inflows to offset its short-dollar positions in the forward market, especially in ⁠the near-term ‌maturity buckets, according to economists at Citi, HDFC Bank and IDFC First Bank.The RBI's net short dollar forward book stood at a record $106.6 ⁠billion as of May 31, reflecting its heavy use of forwards to cushion the rupee from volatile oil prices and weak capital flows.
