Indian equity benchmarks BSE Sensex and NSE Nifty50 are likely to open higher on Tuesday tracking gains across most of their Asian peers, shrugging off overnight losses on Wall Street, as investors digested remarks from Fed officials about plans for hikes in benchmark interest rates. Singapore Exchange (SGX) Nifty futures — an early indicator of the Nifty index — gained as much as 68 points or 0.4 percent to 18,445.5 ahead of the opening bell on Dalal Street.
