The rupee today breached the 63-level for the first time against the US currency in late evening trade at the Interbank Foreign Exchange market on higher demand for dollar, particularly from oil importers.
The currency tumbled by Rs 1.65 to 63.30, despite a series of measures by RBI and government measures to arrest the local currency's slide.
Meanwhile, the BSE benchmark Sensex fell by 291 points to end at over 4-month low of 18,307.52 today, as the investor sentiment had taken a hit with rupee touching new lows.
