Il Nuovo Postiglione - Crises slowing economic growth worldwide: IMF chief

And beyond the humanitarian tragedy and economic crises, the war has exposed fractures in the international system at a time when global cooperation is the only solution, she said.

The war hit as the world was struggling to recover from the ongoing impact of the Covid-19 pandemic, and has caused an acceleration of inflation that endangers the gains of the past two years.

"To put it simply: we are facing a crisis on top of a crisis," Georgieva said in a speech ahead of the spring meetings of the IMF and World Bank.

"The economic consequences from the war spread fast and far, to neighbors and beyond, hitting hardest the world's most vulnerable people," she said.

Families already were struggling with higher energy and food prices and "the war has made this much worse."

The IMF is due to release its updated economic forecasts on Tuesday, which Georgieva said will further downgrade the estimate for global growth that was cut to 4.4 percent in January.

"Since then, the outlook has deteriorated substantially, largely because of the war and its repercussions," she said, and 143 countries will suffer downgrades.

While most will still achieve positive growth, the future is "extraordinarily uncertain," and she warned of a deep divide between rich and poor countries.

- 'Clear and present danger' -

After a decade of low inflation, prices worldwide have surged amid strong demand for goods that outstripped supply as economies began to return to normal, but the Russian invasion of Ukraine in late February and the sanctions imposed on Moscow pushed fuel and food prices up sharply.

Ukraine and Russia are major grain producers, and Russia also is a key source of energy for Europe.

"The root cause of what we face today is the war and it is the war that must end," Georgieva said in a discussion following her speech to the Carnegie Endowment for International Peace.

Inflation, which has hit a four-decade high the United States, "has become a clear and present danger," she said, noting the trend will likely last longer than expected.

"This is a massive setback for the global recovery," she said.

It also complicates policymaking: major central banks are raising interest rates to contain prices, but that increases borrowing costs for emerging markets and developing nations, which face high debt burdens.

"This is the most universally complex policy environment of our lifetime," she said.

- 'Fragmentation' -

Ending the war and the pandemic are top priorities, but can only be addressed through international cooperation, said Georgieva, who warned of the growing "fragmentation of the world economy into geopolitical blocs."

The IMF leader, who grew up in Cold War-era Bulgaria, lamented, "I have never thought that I would live to see another war in Europe of the magnitude of the tragedy that is happening in Ukraine."

She noted that the end of the Cold War ushered in "a new era of rapidly increasing prosperity... because of an integrated global economy."

Fractures in that system impair the ability to address the current crises and future challenges, but also could cause a "tectonic shift" that would reshape global supply chains.

"The threat to our collective prosperity from a breakdown in global cooperation cannot be overstated," she said.
