Indian equity benchmarks BSE Sensex and NSE Nifty50 are likely to open lower on Wednesday as Dalal Street returns to trade after a day's holiday. Equities elsewhere around the world fell as investors awaited a key reading on inflation in the US for more clarity on the course of the Fed's hikes in COVID-era interest rates. Singapore Exchange (SGX) Nifty futures — an early indicator of the Nifty50 index — fell as much as 45 points or 0.3 percent to 17,495.5 ahead of the opening bell on Dalal Street.
