The global brokerage firm further said that the Reserve Bank of India would need to raise USD 40 billion by March 2016, just to maintain import cover at the present eight months.
It said the factors that are supporting the Indian rupee include softening of oil prices, the continuation of gold import curbs and rising FII equity inflows.
"We expect the RBI to hold Rs 58-62/USD for now even though the US Dollar has strengthened below 1.30/Euro," BofA-ML said in a research note, adding that rising FII equity inflows at USD 9.6 billion so far this fiscal has also led to a helping hand to the rupee.
The rupee today recovered by 15 paise to 60.24 against the dollar in early trade on increased selling of the American currency by exporters and banks amid sustained foreign fund inflows.
"We continue to expect RBI Governor Raghuram Rajan to buy FX at Rs 58+/USD to guard against contagion," the report noted.
Rajan has also said that RBI is preparing for any rate hikes by the US Federal Reserve by building an adequate level of foreign exchange.
"Any emerging market today is going to look at the currency volatility and say 'whatever money comes in, I'm going to be careful about it, I'm going to build some reserves..," he had said in Chicago last week.
According to the BofA-ML report, restrictions on gold imports is expected to contain the current account deficit at 1.7 per cent of GDP in FY15.
The rupee would price-in the eventual liberalisation of gold imports and this in turn would push up the current account deficit to 2.4 per cent of GDP in FY16, especially if pent up demand leads to a jump in gold imports, it added.
According to BofA-ML gold price is expected to be at USD 1375/oz in 2015.
