The bad news with China's reopening is that it will not only boost global growth, but also energy and commodity prices - hence inflation, the interest rate hikes from central banks and potentially the global Covid cases – which could then give birth to a new, and a dangerous Covid variant, which would, in return, bring the restrictive Covid measures back on the table, and hammer growth," said Ipek Ozkardeskaya at Swissquote Bank.
