Rupee is world's most undervalued currency:
The Indian rupee is the world's most undervalued currency, trading at around 61% below its 'actual' price against the dollar, The Economist's latest Big Mac Index has found.
The Indian rupee opened at a record low of 50.50 per dollar on Thursday as a sharp fall in Asian share prices raised worries of foreigners cutting local equity holdings and repatriating the funds.
