OECD doubles 2021 US growth prediction to 6.5% after Joe Biden's $1.9 trillion stimulus bill

• The OECD ramped up its growth forecast for the US economy in 2021 to 6.5% from 3.2% in December.
• It said the $1.9 trillion stimulus package "will provide a significant near-term boost to activity."
• The organization upped its global growth forecast for 2021 to 5.6% from 4.2% in December.

Huge government stimulus and the rollout of coronavirus vaccines will give the US economy a major boost in 2021, according to the OECD, which more than doubled its forecast for US growth on Tuesday.

The Paris-based economic organization now expects the US economy to grow 6.5% in 2021, up from a prediction of 3.2% in December. The economy shrank 3.5% in 2020 as coronavirus hit, the worst downturn since 1946.

In a report on the world economy, the OECD said Joe Biden's $1.9 trillions stimulus plan would also boost economies around the world, especially Canada, Mexico, the eurozone and China. It now expects the global economy to grow 5.6% in 2021, up from 4.2% in December.

"The significant fiscal stimulus in the United States, along with faster vaccination, could boost US GDP growth by over 3 percentage points this year, with welcome demand spillovers in key trading partners," the report said.

However, it said there were risks on the horizon, including that "slow progress in [global] vaccine rollout and the emergence of new virus mutations resistant to existing vaccines would result in a weaker recovery, larger job losses and more business failures."

Biden's flagship $1.9 trillion stimulus package could be passed by the House on Tuesday after it was approved by the Senate at the weekend. The legislation would send $1,400 checks directly to most taxpayers, and comes after a $900 billion stimulus package was passed in December.

The OECD said in its report Tuesday that "there would be a clear immediate boost from stimulus payments to households, which represent around one-fifth of the overall package of measures."

It roughly estimated the stimulus could raise US output by around 3% to 4% on average in the first full year of the package. The package "will provide a significant near-term boost to activity if enacted in full," it said.

In 2022, the OECD expects the US economy to expand 4%, up from its 3.5% prediction in December.

The organization added the US's major trading partners also stand to benefit, with up to a 1 percentage point boost to output in Canada and Mexico, and up to 0.5 percentage points in the eurozone and China.

The OECD - an economic organization of 37 member countries - said the stimulus package would cause inflation to rise by around 0.75 percentage points a year in 2021 and 2022. But it said the effect after that "is likely to be modest."

China's economy is expected to grow 7.8% in 2021, down from the OECD's 8% prediction in December. Eurozone growth is expected to come in at 3.9%, up from December's 3.6% prediction.
