To drive inflation lower, central banks may need to raise interest rates by an additional 2 percentage points, on top of the 2-percentage point increase already seen over the 2021 average, it said.
But an increase of that size, along with financial-market stress, would slow global gross domestic product growth to 0.5% in 2023, or a 0.4% contraction in per–capita terms, which would meet the technical definition of a global recession, it added.
Malpass said policymakers should shift their focus from reducing consumption to boosting production, including efforts to generate additional investment and productivity gains.
Previous recessions showed the risk of allowing inflation to stay elevated for long while growth is weak, the bank said, noting that the 1982 recession triggered more than 40 debt crises and ushered in a decade of lost growth in many developing economies.
