Currently, the interbank trading rate of the currency is 98.30 per US dollar.
The strong gains by the Pakistani rupee have led to talk in the money market that the dollar will sell for as low as 98 rupee by the end of the fiscal year.
On Tuesday, it gained about 1.10, which led to the dollar selling at 99.95 in the interbank rates and at 100 rupee in the open money market.
This is the first time since last November that the Pakistani rupee had touched 100 per dollar mark in interbank trading.
On Monday, the Pakistani rupee had ended higher at 101.00/101.10 against the dollar as compared to Friday's close of 102.85/102.95.
