Mumbai: The rupee dropped 13 paise to 83.19 in the opening session on rising demand for the US dollar by bankers and importers, dealers at the Foreign Exchange said.

The domestic unit was seen as weak owing to a strong dollar against other world currencies and a weak opening in the equity market.

The rupee recorded intraday highs and lows at 83.12 and 83.22, respectively, the dealer added.
