Like it did in 2009, the Reserve Bank of India could look at launching an exclusive dollar purchase window for state-owned oil importers to meet their oil payments and, in turn, support the falling rupee. The Indian currency today fell to an over two-year low of 52.16 rupees a dollar due to panic purchases by oil companies. The central bank had introduced special market operations for state-owned oil companies to convert their oil bonds into dollars, after the rupee hit an all-time low of 52.18 a dollar on Mar 3, 2009. The move was successful in providing liquidity and financial stability to oil companies, which otherwise would have tapped the foreign exchange market and put pressure on the rupee. Dealers peg oil importers' dollar demand around $6 bln on a monthly basis. "If RBI does this (exclusive dollar purchase window), the demand for the dollar should ease, hence smoothening the fall in the rupee," said a treasury official with a large state-owned oil company.
