The Indian rupee weakened to a two-month low on Tuesday as foreign investors continued to sell. It finally closed at 96.43 against the dollar, down 13 paise from the previous session. Oil prices hovered above $100 a barrel during the day before retracing to $98.45. A strengthening dollar index and rising US yields further added to the pressure, weighing on emerging-market currencies. The rupee remains the worst-performing Asian currency this calendar year, falling 7.3%.
