The rebound of the world economy was the great feature of the year 2021. Anticipated as strong rebounds, they were less strong for some than for others. Governments that injected money into public investment improved their recovery more than those that did not.
2021 has been the one with the highest inflation in the world since the 1970s with Brazil, Turkey and the United States leading the way, but followed by everyone else. The consequence is that central banks around the world initiated interest rate hikes as a way to contain inflation, so the GDP growth rate in 2022 will be very low overall.
It was a good year of economic rebound, but at the cost of high global inflation that central banks will have to face in the years to come. The recovery was rapid due to increases in government deficits and debt, and even so, spending still does not contribute to economic growth.
