The rupee has fallen to historic lows since an artificial cap on the currency was lifted last week to move it to a market-based exchange rate. That removed support previously provided by the country's currency exchange association.
Moving the rupee to a market-based exchange rate is one of several conditions set by the International Monetary Fund (IMF) to start talks over a ninth review of Pakistan's $7 billion bailout programme.
The IMF has announced its delegation are to arrive in
Islamabad on January 31 for talks through February 9.
