A weak dollar in overseas markets and selling of the US currency by exporters and banks supported the rupee in opening trade, forex dealers said.
Further, a higher opening in the domestic equity market and strong FII inflows influenced the rupee uptrend, they added.
On Friday, the rupee had lost 5 paise to end at 65.46 against the US currency on dollar demand from importers and suspected RBI intervention, ending its four-day dream run.
