The rupee strengthened further by 27 paise to close at a four-month high of 69.58 against the US currency on Friday, extending gains for a fourth day in a row aided by easing crude oil prices and firm stock markets.
The rupee traded firm against the US currency despite a firm dollar overseas, signalling a change in sentiments of forex speculators, analysts said.
At the Interbank Foreign Exchange (Forex), the rupee opened higher at 69.68, and soon gathered momentum to touch a high of 69.57.
The domestic unit, however, pared some gains and settled the day up by 27 paise at 69.58 a dollar, a level not seen since August 1.
On Thursday, the rupee had vaulted 77 paise to a three-month high of 69.85 per US dollar.
"The INR remained unchanged today despite dollar strength, signaling changing sentiments amongst forex speculators, a rise in FII inflows and crude stabilising below $60," said Sunil Sharma, Chief Investment Officer, Sanctum Wealth Management.
