Below is a useful diagram from McKinsey & Company that compares the money used to assist the economies after the outbreak of Covid-19 and the GFC in 2017. Governments allocated US$10 trillion for economic stimulus in just two months—and for some countries, their response as a percentage of GDP was nearly ten times what it was in the financial crisis of 2008–09.
Countries in Europe have allocated around US$4 trillion which is approximately 30 times than that of the Marshall Plan in today’s value – the Marshall Plan was valued at $15bn in 1948. The size of government responses are unprecedented and they, with central banks, are moving into new territory. Global debt is estimated to reach US$300 trillion by the March quarter in 2021 with global GDP taking a huge hit. However unlike the GFC there seems to be an end point once an effective vaccine has been found but many jobs and businesses have gone and it will take time before new ones appear.
