The borrowing from the International Monetary Fund is a disaster.
That fund imposes a lot of catastrophic restrictions that burden many countries, so countries will not borrow from it.
you mean the World Bank because it is the one that grants loans and finances and not like the monetary fund that has harsher terms.
Countries will sell their reserves of gold and silver, and countries with the least reserves will print the money.
Printing more money will damage their economy itself because it will result into hyperinflation so getting loan is better than complete collapse.But selling their reserves could be a better option, anyway life after covid 19 is going to be tough because countries will starts to ask more taxes to compensate with the early losses so people might be thinking about moving to cryptos as soon as possible.
