In an annual report, the World Bank, which lends money to poorer countries for development projects, said it had slashed its forecast for global growth this year by nearly half, to just 1.7%, from its previous projection of 3%. If that forecast proves accurate, it would be the third-weakest annual expansion in three decades, behind only the deep recessions that resulted from the 2008 global financial crisis and the pandemic in 2020.

Though the United States might avoid a recession this year — the World Bank predicts the U.S. economy will eke out growth of 0.5% — global weakness will likely pose another headwind for America’s businesses and consumers, on top of high prices and more expensive borrowing rates. The United States also remains vulnerable to further supply chain disruptions if COVID keeps surging or the war in Ukraine worsens.

And Europe, long a major exporter to China, will likely suffer from a weaker Chinese economy.

The World Bank report also noted that rising interest rates in developed economies like the United States and Europe will attract investment capital from poorer countries, thereby depriving them of crucial domestic investment. At the same time, the report said, those high interest rates will slow growth in developed countries at a time when Russia’s invasion of Ukraine has kept world food prices high.

The impact of a global downturn would fall particularly hard on poorer countries in such areas as Saharan Africa, where the World Bank predicts per capita income will grow just 1.2% in 2023 and 2024. That is such a tepid pace that poverty rates could rise.

“Weakness in growth and business investment will compound the already devastating reversals in education, health, poverty, and infrastructure and the increasing demands from climate change,” said David Malpass, president of the World Bank.

The report follows a similarly gloomy forecast a week earlier from Kristina Georgieva, the head of the International Monetary Fund, the global lending agency. Georgieva estimated on CBS’ “Face the Nation” that one-third of the world will fall into recession this year.

“For most of the world economy, this is going to be a tough year, tougher than the year we leave behind,” Georgieva said. “Why? Because the three big economies — U.S., E.U., China — are all slowing down simultaneously.”

The World Bank projects that the European Union’s economy won’t grow at all next year after having expanded 3.3% in 2022. It foresees China growing 4.3%, nearly a percentage point lower than it had previously forecast, and about half the pace that Beijing posted in 2021.

The bank expects developing countries to fare better, growing 3.4% this year, the same as in 2022, though still only about half the pace of 2021. It forecasts Brazil’s growth slowing to 0.8% in 2023, down from 3% last year. In Pakistan, it expects the economy to expand just 2% this year, one-third of last year’s pace.

Other economists have also issued bleak outlooks, though most of them not quite as dire. Economists at JPMorgan are predicting slow growth this year for advanced economies and the world as a whole, but they don’t expect a global recession. Last month, the bank predicted that slowing inflation will bolster consumers’ ability to spend and power growth in the United States and elsewhere.

“The global expansion will turn into 2023 bent but not broken,” the JPMorgan report said.
