"Investors were in a cautious mode in anticipation of the release of US inflation statistics, which will set the tone for the next FED policy meeting. The US CPI inflation during July is projected to remain high, in line with June inflation levels. This, along with strong job data, will compel the FED to keep taking a tough approach to rein in high inflation levels," said Vinod Nair, Head of Research at Geojit Financial Services.
