"The strength in the rupee was mainly attributed to weakness in the US dollar and sharp gains in the euro," said Abhishek Goenka, CEO of India Forex Advisors.
The rupee shifted between gains and losses after a news report that the Reserve Bank of India is considering closing the forex swap window for oil companies, which the RBI later clarified was still open, Goenka said.
The RBI said in a release that the oil marketing companies swap window remains operational and that any tapering of the facility will be done in a calibrated manner.
