The total amount of money owed by every single person and country in the world is US$215 trillion, but the world has only US$36.8 trillion in cash and bank deposits.
For purists, who believe “money” refers only to physical “narrow money” (bank notes, coins, and money deposited in savings or checking accounts), the total is somewhere around $36.8 trillion. If you’re looking at “broad money,” which isn’t just physical money and includes any money held in easily accessible accounts, the number is about $90.4 trillion.
As for money owed by every single person and country in the world, the grand total is $215 trillion, with some 33% of it borrowed in the last decade.
