BENGALURU: Indian shares dropped on Monday after their longest winning run since last October, after index heavyweight Reliance Industries slid following a weaker-than-expected earnings report, while markets eyed policy cues from the upcoming central bank meetings.

The NSE Nifty 50 index was down 0.59% at 16,621.05, as of 0457 GMT, while the S&P BSE Sensex slipped 0.65% to 55,709.97, after rising for six straight sessions. Last week, the indexes rose more than 4% each in their best performances since February 2021 amid expectations that inflation had peaked.

"Results and macroeconomic cues are very key triggers for the market as it consolidates following a sharp pullback," said Mayuresh Joshi, head of equity research at William O'Neil & Co in India.

"While rate hikes are a given, there are expectations that inflation will start receding in coming months. What needs to be seen is how much growth and spending will come down."

The U.S. Federal Reserve is expected to deliver another 75-basis point interest rate hike later this week as it looks to tackle stubbornly high inflation, while India's central bank is set to meet next week to decide on policy.
