The Indian rupee weakened against the US dollar due to a strong greenback in international markets. However, the rupee was supported by foreign institutional investor (FII) inflows and falling crude oil prices. The dollar index, which measures the strength of the greenback against other currencies, was trading higher. Brent crude futures also declined due to signs of weakening demand in China and an increase in US crude stockpiles. In the domestic equity market, the BSE Sensex and NSE Nifty both recorded losses.
