Major bourses in Asia showed lacking direction on Friday, ahead of Fed Chair Powell’s speech at the Jackson Hole summit. Traders weighed the PBoC’s move to make its biggest weekly cash injection into China’s banking system since February against rising the Delta strain cases globally. The Shanghai Composite led the gains and is on track to surge more than 2.5% weekly. The Nikkei 225 fell, however, as weekly foreign outflows in Japanese stocks hit the highest in over 3 months.
