"Global growth is slowing sharply, with further slowing likely as more countries fall into recession," World Bank President David Malpass said, adding his worry that these trends would persist, with devastating consequences for emerging market and developing economies.
Synchronized interest rate hikes under way globally and related policy actions were likely to continue well into next year, but might not be sufficient to bring inflation back down to levels seen before the Covid-19 pandemic, the bank said.
Unless supply disruptions and labor-market pressures subsided, the global core inflation rate, excluding energy, could stay at about 5 per cent in 2023, nearly double the five-year average before the pandemic.
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 per cent in 2023, or a 0.4 per cent 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.
World Bank vice president Ayhan Kose said a recent tightening of monetary and fiscal policies would help cut inflation, but the highly synchronous nature of the measures could compound the situation and steepen the global growth slowdown.
The study suggested that central banks could combat inflation without touching off a global recession by communicating their policy decisions clearly, while policymakers should put in place credible medium-term fiscal plans and continue to provide targeted relief to vulnerable households.
