The rupee was trading strong at 66.69 due to increased dollar selling by banks and exporters amid a volatile trade in the domestic equity market.

Forex dealers said the dollar faced some headwinds against other currencies overseas after core US inflation rose less than forecast in September. Continued inflows by foreign funds too supported the rupee uptrend.

The domestic unit opened strong by 5 paise at 66.68 at the Interbank Foreign Exchange market today. It hovered in a range of 66.84 and 66.66 before quoting at 66.69, up 4 paise at 3.05 pm local time.

The rupee had gained 15 paise to end at 66.73 yesterday on fresh bout of dollar selling amid weak overseas sentiment.

Meanwhile, the benchmark BSE Sensex was trading down by 66 points or 0.24 per cent at 27,992.09.

In the overseas markets, sterling hit an eight-day high on Wednesday, building on its strongest one-day gains in over three months on a trade-weighted basis, after a UK government lawyer said parliament would have to ratify any deal to take Britain out of the EU.

The dollar stepped back from a seven-month high against an index of currencies on Wednesday after US consumer prices showed a moderation in underlying inflation, prompting markets to trim bets on a December Federal Reserve rate hike.
