The answer is simple, every country printed lot of money in 2020 to keep their economy alive while there is worldwide lockdown so now the results are coming due to that excess money in the circulation. Also another reason is war between Russia and Ukraine affected the economy all around the world, increased the cost of fuel so people lost their spending power now feeling the loss to the value for the money they own.
Even during the global pandemic, there was talk that the consequences of this would be very tangible for many countries. I'm not sure if this has affected the whole world, in my opinion the Scandinavian countries did not succumb to this panic very much and they did not have such significant restrictions. Therefore, their position and economy is in a much better condition.
They did not follow everyone else, did not succumb to the herd principle, but decided to make decisions on their own, to some extent I support this approach, as we see it was right.
But besides the pandemic, there are a number of significant reasons that affect the global economy. In any case, it is also cyclical, after a period of development, there is always a decline.
