COVID-19 pandemic has made the natural levels of inflation variable, and therefore monetary policies set by governments may fail to bring inflation under control and maintain levels according to expectations, for example, most countries are trying to maintain inflation between 2%-5%.
Now we have an energy crisis and I believe that the dollar is linked in one way or another to the price of a barrel of oil, which prices most things in our lives, and with the fluctuation of energy prices, political risks and others, it will become difficult to maintain low inflation levels and a price of 100 dollar per barrel of oil without high inflation more than 5%.
Therefore, I do not think that governments will succeed in keeping inflation rates under control during the next three years.
This is the problem that Biden will face all his presidency. He took over from a guy who distributed more than %50 of the giveaways to companies (check the covid relief packages, less than %50 went to individuals each time he did it) and that caused the dollar to be inflated. Now Biden will have to explain to people that he did not caused it, I mean sure maybe a part of it but he took over a nation that printed more than %20+ of debts amount in a single year, yes thats right, for the past 250 or so years, %20+ of the debt amount got printed in just one year. So of course Biden is responsible for some stuff but not all of it. He will be seen as the president who had bad inflation during his term. Quite similar to Obama taking over Bush 2008 crisis, it always happens, a republican president leaving a bad economy to be replaced bye a democrat.
