"The Indian rupee is now at its real value," he told reporters.
He, however cautioned that "there should be no exuberance".
Extending its rising streak for the fourth straight day, the Indian rupee appreciated by 51 paise to trade at nearly four-month high of 60.90 against the dollar in early trade today on sales of the US currency by banks and exporters and sustained foreign capital inflows.
Besides, a higher opening in the domestic equity market, where the BSE Sensex soared to an all-time high of 21,483.74 points after BJP's victory in state Assembly elections and strengthening of other currencies against the US dollar overseas, also supported the local currency, forex dealers said.
The Indian rupee had touched a life time low of 68.85 against the dollar in the last week of August after the US Federal Reserve started discussions on tapering its fiscal stimulus.
A record current account deficit (CAD) on back of high gold imports too was pressuring the rupee value.
However, there has been significant improvement on the CAD as it narrowed to USD 5.2 billion or 1.2 per cent of GDP in the second quarter of the current fiscal. The deficit was at USD 21 billion, or 5 per cent of the GDP in the same period of last year.
