Benchmark indices BSE Sensex and NSE’s Nifty 50 are likely to open lower on Tuesday following losses in global markets over escalating US-China tensions. Moreover, tension in Jammu and Kashmir over scrapping of Article 70 and continued foreign capital outflow may also weigh on the markets. Asian stocks declined after US designated China a currency manipulator. Indian shares ended over 1 percent lower in the previous session over selloffs in global equities. At 7.05 AM, the SGX Nifty futures traded 81.50 points, or 0.75 percent, lower at 10,788, indicating a negative start for the Sensex and the Nifty 50.
