What it concludes

• Physical currency used to correlate closely to the total supply of money, but abstraction through banking and paper instruments helps money move and grow.
• Fractional-reserve banking creates money when loans are issued, operating on the reality that not all depositors withdraw funds at once.
• Historically, moving money physically between different banks was inefficient and risky, leading to the development of checks, clearinghouses, and standardized routing.
• The 1860s National Currency Acts and the Federal Reserve Act of 1913 centralized processing and modernized check clearing in the United States.
• Modern digital payment networks like ACH, SWIFT, and Wise enable fast, secure domestic and international transfers by replacing physical cash movement with ledger entries and messaging systems.
