NEW YORK (BLOOMBERG) - The global middle class shrank for the first time in decades last year because of the Covid-19 pandemic, with almost two-thirds of households in developing economies reporting they suffered a loss in income, according to two new estimates based on World Bank data.
In a study published Thursday (March 18), researchers at the non-partisan Pew Research Center found that the ranks of the global middle class - those "middle income" and "upper-middle income" people earning US$10-US$20 (S$13.44 - S$26.89) and US$20-US$50 per day respectively - fell by 90 million people to almost 2.5 billion last year.
That helped swell the ranks of the poor, or those living on less than US$2 a day, by 131 million, Pew estimated.
The Pew data on the middle class actually understates the impact because an estimated 62 million high-income people, or those earning US$50 or more per day, dropped into the middle tier as a result of the pandemic, said Mr Rakesh Kochhar, the study's author.
That suggests the number of people who went into the crisis as members of the global middle class and fell out actually topped 150 million last year, according to Pew's estimates - more than the population of France and Germany combined.
"In modern history it is hard to come up with examples where you saw such a sharp downturn in global economic growth," Mr Kochhar said in an interview.
The impact also may not be over. Concerns are growing about the potential consequences of a slower recovery in emerging economies and the continuing fallout from the crisis.
Brazil's central bank on Wednesday announced its biggest increase in its policy rate in a decade in response to growing fears of inflation. Economists are also watching the possible fallout for emerging nations of rising US Treasury yields and a strengthening dollar as the US economy accelerates.
If the Pew estimate holds true in actual World Bank income data still being gathered, it would mark an end to a pattern that has seen the global middle class expand without fail since the 1990s thanks to the rapid growth of developing economies like China and India.
When Pew last calculated the number of the world's middle-income earners - or those with incomes of US$10-US$20 per day - in 2011, they made up 13 per cent of the global population.
By 2019, that had grown to nearly 18 per cent, Mr Kochhar said, with an average of 50 million people a year joining the middle-income ranks over the past decade.
In a separate paper published Monday based on surveys of 47,000 households in 34 developing countries with a collective population of almost 1.4 billion people, researchers at the World Bank found that 36 per cent of households saw job losses last year and almost two-thirds saw incomes fall.
The result was the first increase in global poverty seen since the Asian financial crisis of 1997-98, the bank's researchers wrote.
As in many rich countries, the surveys of countries ranging from Burkina Faso to Colombia, Indonesia and Vietnam show the burden of the economic hit disproportionately fell on women, young people and the self-employed in urban centers.
But they also point to the consequences that slower recoveries are expected to have. While the US has unleashed unprecedented fiscal rescue efforts for its economy, many developing economies have had smaller resources to draw on.
According to the World Bank, as of September 2020, advanced economies had on average spent 7.4 per cent of gross domestic product on rescuing businesses and people hit by the pandemic versus 3.8 per cent of GDP in emerging markets and 2.4 per cent in low-income developing countries.
With countries like the US moving rapidly to vaccinate their populations and extending their government rescue efforts since then - as with the passage through Congress last week of President Joe Biden's US$1.9 trillion American Rescue Plan - the gap has only grown further since then.
The World Bank expects the ranks of the world's poor to continue to grow this year. Its estimate show as many as 124 million people fell below its US$1.90 line for extreme poverty in 2020. That number of new poor is projected to continue growing this year to as many as 163 million people.
What happens next to the ranks of the global middle class will depend heavily on the recoveries in key countries like India and remains hugely uncertain, Mr Kochhar said. If growth bounces back as the coronavirus is vanquished this episode may end up being just "sharp scary roller-coaster ride that is over - in geological time - is over in a flash," he said.
But growth may also be slower to return in many developing countries, he said.
South Asia accounted for more than a third of the decrease in the ranks of the middle class seen last year, according to Pew. Going into 2020, India's economy was expected to grow at a rate of almost 6 per cent over the year. The World Bank now estimates India's GDP will have contracted by 9.6 per cent in the fiscal year to March 31.
