Indian markets are expected to open a tad lower on Thursday as the global sentiments are weak. The US government's debt yields added to a steep decline in March as the yield on the closely monitored 10-year treasury note dipped to a 14-month low and the US yield curve is only exacerbating matters by inverting. However, there seems to be good news from the weather office as the IMD has predicted robust monsoon in 2019 provided there is no unexpected El Nino phenomenon. Volatility is likely to be elevated in today’s session on the back of March series derivatives expiry. At the time of writing, the SGX Nifty was trading lower by 35 points at 11,411.
