Greece’s default on International Monetary Fund (IMF) payments has sent ripples through world financial markets. But nearly all countries carry debt – the international economy runs on debt.

John Metherell reported on this in Washington.

A snapshot of national debt worldwide: 

• In 2003, Argentina defaulted on a $3 billion debt to the IMF. Despite dire predictions at the time, the world economy did not collapse, but it did leave Argentina with a precarious economy.
• Puerto Rico is facing similar trouble. Earlier this week, its governor declared the island was unable to service a debt of about $72 billion. In a last minute move, Puerto Rico paid more than $1 billion in obligations on Wednesday, heading off for now a deepening financial crisis.
• The United States has a national debt of more than $18 trillion.
• Although China’s economy continues to expand – at a slower rate recently – the world’s second largest economy carries debts of more than $5 trillion.
• The U.K. owes in excess of $2 trillion; Spain — another Eurozone country that could be in similar trouble to Greece — has debts of more than $1 trillion; Switzerland owes about $120 billion.
• For many nations owing money, their citizens, children and grandchildren can expect to be paying for national debts for years to come.
