Major bourses in Asia traded mainly in the red on Tuesday, amid worries about the coronavirus Delta variant and its impact on the global economy. The Nikkei 225 led the losses, falling by 0.5%, due to an extension of the state of emergency until August 31st. Stocks in China (-0.5%) and Hong Kong (-0.3%) were also lower, led by a tumble in online gaming shares amid worries over further regulation. The Economic Information Daily, a Chinese state media, published an article that expressed concern over the amount of time spent by youths on online gaming. In Australia, the ASX ended 0.2% lower, as the RBA will continue the bond-buying program at the rate of $5 billion a week until early September and then $4 billion a week until at least mid-November. Stocks in South Korea gained (0.4%), however, rising for the second straight session, buoyed by chip giants and foreigner-buying.
