“While a small percentage of a country’s currency exists in the form of physical cash, the majority exists in digital form, created whenever a financial institution backed by the central bank lends. New money is not created when currency bills are printed, but rather whenever new debt is issued.”

“Keep in mind that these debts are always tied to some interest rate. The interest is already embedded in the contract of debt issuance. Therefore, whenever Ahmad makes a deposit at the bank, he’s essentially telling the bankers “please create more money by issuing debt, and you can make money off of this debt through interest”.

Essentially, every dollar is created through interest. This point is also made in Tariq El Diwany’s book, ‘The Problem with Interest’:
“Bank money cannot be created other than by a loan, and therefore almost inevitably bears interest as a condition for its existence.”
