Rupee depreciates 10 paise against dollar in opening trade

At the Interbank Foreign Exchange (Forex) market, the domestic unit traded 10 paise down at 46.63 a dollar.

It had closed 14 paise higher at 46.53/54 against the dollar in yesterday's volatile trading session.

The Reserve Bank on Wednesday tightened the guidelines for external commercial borrowings by withdrawing relaxations provided to companies to raise money from overseas debt markets, raising fears that capital inflows would be adversely impacted.
However, dollar's weakness overseas kept rupee's losses limited.
