Mumbai: The rupee depreciated 36 paise to 79.51 against the US dollar in opening trade on Thursday, as disappointing macroeconomic data and US-China tensions weighed on investor sentiment.
At the interbank foreign exchange, the rupee opened at 79.21 against the US dollar, then fell to 79.51, registering a decline of 36 paise over the last close.

India's exports dipped, though marginally, for the first time in 17 months in July, while the trade deficit tripled to a record USD 31 billion, fuelled by over a 70 per cent rise in crude oil imports.
