The Covid-19 pandemic and subsequent lockdown measures have thrown the world economy in turmoil. Even as countries are reopening, the World Bank predicts this year, the globe will have its deepest global recession in 80 years.

The pandemic, which has infected some seven million people worldwide, led countries to order citizens to stay at home and business to grind to a halt.

Worldwide gross domestic product – the broadest measure of economic growth – will contract 5.2 percent in 2020, according to a report by the World Bank. That’s despite the unprecedented fiscal and monetary policy support governments around the world have been rolling out. Trillions of dollars have been deployed to help companies stay in business, keep cash in consumers wallets and let financial markets function properly.

Still, advanced economies, such as the United States or Europe, are projected to shrink by 7 percent. America’s economy is expected to contract by 6.1 percent before rebounding in 2021.

This quarter will almost certainly be the worst for the Western world, but most of Asia felt the brunt of the outbreak in the first months of the year.

China, the world’s second largest economy, is projected to grow 1 percent this year, down from 6.1 percent in 2019, before bouncing back.

The pandemic recession will probably leave deep scars: Investments will stay lower in the near term, and global trade and supply chains will erode to some extent. On top of that, millions of people have been laid off, causing the biggest blow to America’s labor market since the Great Depression. The US Federal Reserve has stressed its concern about laid-off workers getting detached from the labor force as a result of the crisis.

The recession would be even worse if it took longer than expected to bring the pandemic under control, or if financial stress forced a number of companies into bankruptcy.

On Monday, a monthly survey from the American National Association of Business Economics found that a second wave of infections was the biggest risk to the US economy.

Emerging economies are in particular danger, because their health care systems are less resilient and they are more exposed to woes in the global economy through supply chains, tourism and reliance on commodity and financial markets, the World Bank report said.

At the same time, low oil prices, which collapsed in April, could help jump starting the economy in the initial stages of reopening, the World Bank acknowledged.
