The US economy is growing at its fastest pace since 1984

President Joe Biden's $1.9 trillion stimulus package will boost the US economy and drive faster global growth this year, the International Monetary Fund said Tuesday, though it warned that many countries continue to suffer from the pandemic and are at risk of being left behind.

The US economy will surpass its pre-pandemic size as growth reaches 6.4% this year, the IMF said, up 1.3 percentage points from the group's forecast in January. The rebound will help the global economy expand 6% in 2021, an upgrade of 0.5 percentage points from the IMF's previous outlook. The estimates are broadly in line with Wall Street's expectations. "At $1.9 trillion, the Biden administration's new fiscal package is expected to deliver a strong boost to growth in the United States in 2021 and provide sizable positive spillovers to trading partners," the IMF said in a report. Other governments and central banks around the world have also pumped trillions into the global economy.
