Why is Sri Lanka bankrupt?
I dont think a country can become banckrupt like a business can.
It can run default but there is no international law that can force a country to pay his debts.
Why Sri-lanka runed default is due to many causes, but there is a initial cause : The debt.
After the country has faced difficulties due to loss of tourism, rating agencies have caused the change of the credit rates (around 15% if i good remember)
Sri-lanka needed therfore more income to refund the credit of the debt, but unfortunatly they had less income...
This is a lockdown system that finalize the "bankrupt" of a country already facing economic difficulties.
Now, the MFI decide of the politic of the country, or they will never again be able to have a healthy economy.
This imply, like for Greece, selling for nothing all the properties of the country (airports, ports, roads, national society etc etc).
