The rupee weakened to 64.13 as the dollar edged higher against the yen on Monday, pulling away from last week's near 4-month low, with rising tensions between the United States and North Korea seen as the key to the near-term outlook.
The dollar rose 0.3 per cent to 109.52 yen, getting some respite after having fallen to as low as 108.72 yen on Friday, its lowest since April 19.
The domestic unit opened strong by 14 paise at 63.99 at the Interbank Foreign Exchange market today. It hovered in a range of 64.13 and 63.93 before quoting at 64.13, down 14 paise at 4.45 pm local time.
The rupee had lost 5 paise to close 64.13 against the US currency on Friday due to sustained demand for the American currency from importers and corporates.
Meanwhile, the broader NSE index ended higher by 83.35 points or 0.86 per cent at 9,794.15, its biggest one-day percentage gain since July 10. The benchmark BSE index closed up 235.44 points or 0.75 per cent at 31,449.03, its biggest gain since July 19.
