The rupee erased its early loss against the dollar this morning and was up marginally by two paise at 55 rupees 65 paise a short while ago. The gain was attributed to the mild selling of the American currency amid its weakening against other currencies in the overseas forex markets.Earlier in its opening trade the rupee resumed slightly lower at 55 rupees 69 paise a dollar as against the last closing level of 55 rupees 67 paise.
