Again, the all-time low level was set at Rs170.48 on Wednesday last. According to currency dealers, higher external payments put pressure on the dollar’s demand. They said the hike in the international oil and food prices remained one of the major reasons for the rupee depreciation. They said that widening of trade deficit and the current account deficit also deteriorated the market sentiments.
