US stocks on Thursday closed lower after the European Central Bank kept key interest rates steady but disappointed some by not announcing additional measures to boost Europe's sluggish economy. US consumer credit surged up by $17.7 billion in July after climbing by an upwardly revised $14.5 billion in June. Economists had expected consumer credit to rise by $15.6 billion compared to the $12.3 billion increase originally reported for the previous month," according to a report by SMC global.

The Indian rupee also fell in early trade on Friday for the second consecutive session. The currency opened at 66.57 per dollar, down 16 paise compared to previous day's closing value of 66.41 a dollar.
