The International Monetary Fund (IMF) on Tuesday slashed the global growth forecast for 2022 to 3.2 percent, down by 0.4 percentage point from the April projection, according to its newly released update to the World Economic Outlook (WEO).

Several shocks have hit the world economy already weakened by the COVID-19 pandemic, including higher-than-expected inflation worldwide -- especially in the United States and major European economies -- triggering tighter financial conditions, and further negative spillovers from the Ukrainian crisis, the WEO update said.

The global economy "is facing an increasingly gloomy and uncertain outlook," IMF chief economist Pierre-Olivier Gourinchas told a virtual press conference Tuesday, noting that many of the downside risks flagged in the IMF's April WEO have begun to materialize.

"Inflation has also broadened in many economies, reflecting the impact of cost pressures from disrupted supply chains and historically tight labor markets," he said.

Global inflation has been revised up due to food and energy prices, and is anticipated to reach 6.6 percent in advanced economies and 9.5 percent in emerging markets and developing economies this year -- upward revisions of 0.9 and 0.8 percentage point respectively, according to the WEO update.

In 2023, disinflationary monetary policy is expected to bite, with global output growing by just 2.9 percent, it said.

"There is one overwhelming priority at this point, and it is to bring back price stability in advanced economies and in emerging markets," Gourinchas told reporters.

Going forward, it's very clear that the tightening by major central banks is going to have a continued effect on the rest of the world, he noted.

First, there's going to be reduced demand and economic activity at the global level, which will weigh on countries that rely a lot on the export sector for growth, he said.

Second, the tightening in the U.S. and other central banks is also leading to a major appreciation of the U.S. dollar against emerging market currencies, increasing inflation pressures in these countries, he said.

Third, there is a general tendency by investors to move away from emerging market economies and seek safe havens in a cycle like this, investing in U.S. treasuries or other safe assets, Gourinchas said, noting that there has been "persistent" capital flows moving out of emerging markets in the last four or five months.

"So things have not been too disorderly up until now, but of course we are concerned as to whether this might continue in the future," he told reporters.

Gourinchas noted that the risks to the outlook are "overwhelmingly tilted to the downside."

Downside risks include: the Ukrainian crisis could lead to a sudden stop of European gas imports from Russia, inflation could remain stubbornly high if labor markets remain overly tight or inflation expectations de-anchor, or disinflation proves more costly than expected, and tighter global financial conditions could induce a surge in debt distress in emerging markets and developing economies, he explained.

In a plausible alternative scenario where some of these risks materialize, inflation will rise and global growth will decelerate further to about 2.6 percent this year and 2 percent next year -- a pace that growth has fallen below just five times since 1970, he said.

"So 2 percent is really a sort of a low number for the global economy. That's a sense in which we're getting close, really close to a global recession," he told reporters.

Under this scenario, both the United States and the euro area will experience near-zero growth next year, with negative knock-on effects for the rest of the world, he added.
