How the pandemic became stagflationary

IT HAS BEEN a summer of unpleasant surprises for the world economy. America, Europe and China are growing more slowly than investors had hoped. Consumer prices are rising uncomfortably fast, especially in America. Even in the euro area, used to tepid inflation, prices in August were 3% higher than a year earlier, the most in a decade. Economies are troubled by shortages of parts and labour, slow and expensive shipping and the bewildering variation of lockdown measures.The spread of the Delta variant is to blame, but the way the pandemic is affecting the economy is shifting. The world had become accustomed to the virus battering growth, as waves of infection caused a sudden stop in activity, and prices moderated or even fell. Delta, by contrast, looks like a stagflationary force that is sapping growth less dramatically but firing up inflation.
