Rising for the sixth straight day, the rupee strengthened by 8 paise to 63.32 against the dollar in early trade on Tuesday at Interbank Foreign Exchange on sustained selling of the American currency by exporters and banks.
Forex dealers said increased capital inflows as well as higher opening in the domestic equity supported the rupee. They said, however, greenback's strength against other currencies overseas capped the gains.
The rupee had ended higher by 4 paise to 63.40 against the US currency in Monday's trade following consistent selling of dollar by banks and exporters.
