Global economic growth is beginning to show signs of fatigue while many countries, particularly in Asia, are struggling to curb the highly contagious Delta variant of the coronavirus and have been forced into some form of lockdown. The spectre of elevated inflation, which the market has long feared, is also haunting investors. Economists at Bank of America downgraded their forecast for U.S. economic growth to 6.5% this year, from 7% previously, but maintained their 5.5% forecast for next year. "As for inflation, the bad news is it"s likely to remain elevated near term," they said in a note, pointing to their latest read from their proprietary inflation meter which remains high. "The good news is ... we are likely near the peak, at least for the next few months, as base effects are less favourable and shortage pressures rotate away from goods towards services." U.S. Federal Reserve Chair Jerome Powell has repeatedly said any inflation flare-up is expected to be transitory, indicating monetary policy will remain supportive for some while yet. read more Yet, markets remain hard to convince.
