Global economic growth this year and next is expected to continue as the recovery solidifies broadly, but the overall figures mask large downgrades and ongoing struggles for some countries.
"The outlook for the low-income developing country group has darkened considerably due to worsening pandemic dynamics," IMF chief economist Gita Gopinath said.
The setbacks, which she blamed on the "great vaccine divide," will impact the restoration of living standards, and a prolonged pandemic downturn "could reduce global GDP by a cumulative $5.3 trillion over the next five years," she warned.
Meanwhile, advanced economies face "more difficult near-term prospects... in part due to supply disruptions."
That threatens to drive prices higher, especially in the United States, where growth this year will be slower than previously anticipated, even taking into consideration massive spending bills, according to the International Monetary Fund's latest World Economic Outlook.
Output worldwide is expected to grow 5.9 percent this year, only slightly lower that projected in July, before slowing to 4.9 percent in 2022, the report said.
But the wave of infections from the Delta variant of Covid-19 and the drastically lower vaccination rate in developing nations, along with supply bottlenecks, have slowed or pushed back the recovery in many economies.
"The dangerous divergence in economic prospects across countries remains a major concern," Gopinath said in a blog post on the new forecasts.
Advanced economies are expected to regain "pre-pandemic trend path in 2022 and exceed it by 0.9 percent in 2024," she said.
However, in emerging market and developing economies, excluding China, output "is expected to remain 5.5 percent below the pre-pandemic forecast in 2024."
Amid the danger of long-term scarring, "The foremost policy priority is therefore to vaccinate at least 40 percent of the population in every country by end-2021 and 70 percent by mid-2022," she said.
- Delicate US balancing act -
The world's largest economy has benefitted from massive fiscal stimulus, but the Delta wave has undermined progress, and the IMF slashed the United States' growth forecast for this year to six percent, a full percentage point off the July figure.
US growth is expected to slow to 5.2 percent next year, slightly faster than previously expected, but policymakers will face a delicate balancing act amid risks of rising inflation and lagging employment, the fund noted.
Production was slow to recover once the recovery began, creating bottlenecks, notably in semiconductors, and pushing prices higher, while wages also threaten to rise as employers compete for scarce workers.
Central banks must be prepared to act quickly in the face of worsening inflation risks.
"Monetary policy will need to walk a fine line between tackling inflation and financial risks and supporting the economic recovery," the IMF said.
The IMF endorsed the Federal Reserve's stated intention to start to pull back on stimulus by the end of the year, and prepare to lift interest rates in 2022.
But higher US interest rates will have spillover effects for other countries, which will see borrowing costs rise.
Gopinath cautioned that policymakers should avoid "unnecessary policy accidents that roil financial markets and set back the global recovery."
Those include failing to raise the US debt limit "in a timely fashion" or "escalating cross-border trade and technology tensions."
The report notes that trade frictions that predate the pandemic have yet to be resolved and "risk impeding the recovery."
