THE Covid-19 pandemic has triggered the most severe recession in nearly a century and is causing enormous damage to people’s health, jobs and well-being, according to the OECD’s latest Economic Outlook.

As restrictions begin to ease, the path to economic recovery remains highly uncertain and vulnerable to a second wave of infections. Strengthening healthcare systems and supporting people and businesses to help adapt to a post-Covid world will be crucial, it says.

The containment measures brought in by most governments were necessary to slow the spread of the virus and limit the death toll, but they have also closed down business activity in many sectors and caused widespread economic hardship.

Policymakers have used a vast array of exceptional measures to support healthcare systems and people’s incomes, as well as to help businesses and stabilise financial markets.

With little prospect of a vaccine becoming widely available this year, and faced with unprecedented uncertainty, the OECD has taken the unusual step of presenting two equally likely scenarios – one in which the virus is brought under control, and one in which a second global outbreak hits before the end of 2020.

If a second outbreak occurs, triggering a return to lockdowns, world economic output is forecast to plummet 7.6% this year, before climbing back 2.8% in 2021. At its peak, unemployment in the OECD economies would be more than double the rate prior to the outbreaks, with little recovery in jobs next year.

If a second wave of infections is avoided, global economic activity is expected to fall by 6% in 2020 and OECD unemployment to climb to 9.2% from 5.4% in 2019.

The economic impact of strict and relatively lengthy lockdowns in Europe will be particularly harsh. Euro area GDP is expected to plunge by 11 ½ per cent this year if a second wave breaks out, and by over 9% even if a second hit is avoided, while GDP in the United States will take a hit of 8.5% and 7.3% respectively, and Japan 7.3% and 6%. Emerging economies such as Brazil, Russia and South Africa, meanwhile, face particular challenges of strained health systems, adding to the difficulties caused by a collapse in commodity prices, and their economies plunging by 9.1%, 10%, and 8.2% respectively in case of a double hit scenario, and 7.4%, 8% and 7.5% in case of a single hit. China’s and India’s GDPs will be relatively less affected, with a decrease of 3.7% and 7.3% respectively in case of a double hit and 2.6% and 3.7% in case of a single hit.
