MSCI"s index of EM stocks (.MSCIEF) fell 0.5%, with China blue chips (.CSI300) and Hong Kong stocks (.HSI)sliding 1.5% and 0.8% respectively as a lockdown in Xian city to curb the spread of COVID-19 continued for the seventh day. Russian stocks (.IMOEX) fell 0.8%. Turkey shares (.XU100) jumped about 1.2%, while South African shares (.JTOPI) inched up.

"Regardless of how "variant risks" play out, the process of emerging from the COVID tunnel will be fraught with more heat than light... Especially in EM economies hit by mounting deficits and debt," Mizuho analysts wrote in a note. "If caught wrong-footed, this may trigger credit risk warning lights. Above all, with a hawkish Fed set to lead rate hikes, higher global yields and a stronger USD means hot money could leave EM economies out in the cold." An index of riskier currencies gained for a seventh straight session. China"s yuan edged higher, while South Africa"s rand firmed 0.2%. Higher oil prices just about kept exporter Russia"s rouble from slipping into the red. Turkey"s lira was down around 2% at 12 per dollar on the day, bringing losses so far this week to 12%. The beleaguered currency had rebounded more than 50% from record lows around 18 last week, after the country announced some support measures. Despite the central bank promising support, worries persisted over soaring Turkish inflation and unorthodox monetary policy. A Reuters poll saw annual inflation topping 30% this month. The lira is down 38% in 2021.
