Mumbai, May 23 - Recording its intra-day low of 56.21 for the sixth session in a row, the rupee also closed an an all-time low of 56.00, down by another 61 paise or 1.10 pct, against the Greenback on sustained heavy dollar demand from importers and some corporates amid weakness in the local stocks, extending losses for the third straight day in a row.

Firm dollar overseas and continued capital outflows also weighed on the rupee.

At the Interbank Foreign Exchange (Forex) market, the domestic unit opened weak at 55.65 a dollar from previous close of 55.39 and immediately touched a high of 55.52.

Later, it continued its downtrend to log a life-time intra-day low of 56.21 before recovering some ground on suspected intervention by the apex bank to close at 56, which was also to be an all-time closing low.

The Indian bemchmark sensex today closed down by 78.31 points or 0.49 pct after plunging by 156.85 points or 0.97 pct.

The dollar index was up by nearly 0.04 per cent against its major six rivals ahead of a meeting of European leaders with renewed fears that Greek would leave the euro bloc dampening appetite for riskier assets.

Mr. Pramit Brahmbhatt, CEO, Alpari Financial Services (India) said,"The INR plummeted close to 1.1 pct from its previous close on weak global currencies. The EURO tested its twenty one month low against dollar and also the GBP moved below the 1.5700 mark. The ongoing global weakness in currencies has led to the steep fall in INR." PTI
