The rupee on Friday tanked by a massive 55 paise to close at over one-month low of 54.80 a dollar, strengthening on global markets tracking favourable US job data and oil-related forex payments by Indian refiners.

“The factors that hit rupee on Friday are mainly external. Favourable US job data pushed up the dollar. Additionally, the Greenback strengthened against yen. On the domestic front, heavy dollar demand from oil importers kept the local currency weak,” said N.S. Venkatesh, Head (Treasury) at IDBI Bank.

The rupee commenced the day sharply lower at 54.57 against previous close of 54.25 at the Interbank Foreign Exchange (Forex) market.

As the day progressed, it recovered some ground and rose to 54.44 but again plunged later to 54.81, before settling down at 54.80, a fall of 55 paise, or 1.01 per cent, against the dollar from its previous close. This is the rupee’s lowest level since April 5 this year, when it had hit a low of 54.81.

Foreign institutional investors put Rs. 544.11 crore into local equities today, according to BSE provisional data.

The dollar index, which tracks the performance of the greenback versus a basket of six other major currencies traded positively after US new claims for unemployment benefits dropped to the lowest level in more than five years.

Meanwhile, the BSE benchmark Sensex rose to 20,082.62, a net rise of 143.58 points.
