Money Printing in general
First of all, we need to make a distinction between money creation by central banks and fractional-reserve banking. Usually, the term money printing or “printer goes brrrrrr” refers to the creation of new central bank money, which is primarily created by central banks through:
- Open Market Operations: Buying government securities, which injects money into the banking system by increasing bank reserves. This is often done electronically, not by physically printing money.
- Quantitative Easing (QE): Purchasing assets to inject money directly into the economy, aiming to stimulate economic activity by increasing the money supply.
- Setting Reserve Requirements: Although less about creating money, lowering reserve requirements can indirectly influence money creation by allowing banks to lend more, but as of recent policy changes, this has been set to zero in some systems, shifting focus to interest rates.
- Interest on Reserves: By adjusting the interest rate paid on reserves, central banks influence how much banks are willing to lend, thereby indirectly affecting money creation.
This is the first step of money creation, although printing money is usually connected to one of the aforementioned processes, the second step creates much more money through the expansion of credit.
The Mechanics of Fractional-Reserve Banking
The Concept
In fractional-reserve banking, banks accept deposits from customers and only keep a small fraction of these deposits in reserve, lending out the rest. This practice essentially creates new money because:
- Deposits: When you deposit money, say $1,000, into a bank, that money doesn’t just sit there.
- Reserves: If the reserve requirement is 10%, the bank keeps $100 as reserves.
- Loans: The remaining $900 can be loaned out. Here’s where money creation begins.
Note: Current reserve requirements of the FED (Source) and the ECB (Source) are set at 0% respectively 1%.
Example Calculation of Money Creation
- Initial Deposit: You deposit $1,000 into Bank A.
- Bank A’s Action:
- Keeps $10 (1%) as reserve.
- Loans out $990 to another customer.
- The $990 Loan: This $990, when spent, might end up in Bank B as someone’s deposit.
- Bank B’s Action:
- Keeps \(9.9 (1% of \)990) as reserve.
- Can loan out $980.1
- Continuation: This process repeats, with each cycle creating new deposits from loans.
The Deposit Multiplier (m) can be calculated as:
- m = 1 divided by Reserve Ration = 1 / Reserve Ration
If the reserve ratio is 1%:
- m = 1 / 1% = 1 / 0.01 = 100
This means, theoretically, an initial deposit of $1,000 could expand to:
- \(1,000 times 100 = \)100,000
- However, in practice, this is tempered by factors like cash holdings, loan demand, and banks holding excess reserves.
Historical and Economic Context
- Evolution from Goldsmiths: The system has its roots in the practices of goldsmiths who issued notes for gold deposits, which eventually circulated as money. This practice evolved into the modern banking system where notes (now digital entries) represent claims on money.
- Regulation and Central Banking: Over time, central banks like the Federal Reserve in the U.S. were established to regulate this process, provide stability, and act as lenders of last resort. The Fed’s tools include setting reserve requirements, though this has become less relevant with the shift to a 0% reserve requirement.
Criticisms and Alternatives
- Risk of Bank Runs: Critics argue that fractional-reserve banking makes the system vulnerable to bank runs, where too many depositors demand their money back at once, which the bank cannot cover since most of the money is loaned out.
- Vollgeld Initiative and Full-Reserve Banking: Movements like Switzerland’s Vollgeld Initiative have proposed shifting to full-reserve banking, where banks must hold 100% of deposits in reserve, preventing them from creating money through lending. However, this would significantly alter how banks operate and make profits. *** Modern Adjustments**: The move to a 0% reserve requirement in the U.S. reflects a shift towards using other monetary policy tools like interest rates on reserves to control money creation and economic stability.
Real-World Implications
- Money Supply Control: While banks create money through loans, central banks like the Federal Reserve influence this through monetary policy, adjusting how much money banks can create.
- Economic Stability: The zero reserve requirement might seem to allow infinite money creation, but in reality, banks are constrained by capital requirements, risk assessments, and economic conditions.
Conclusion
Fractional-reserve banking is a dynamic system that significantly influences economic growth by expanding the money supply through debt. While it allows for economic expansion, it also introduces risks of instability, which central banks attempt to mitigate through various policy tools. Understanding this system helps demystify how money flows and grows within an economy, showcasing both its capacity for economic stimulation and its inherent risks. As we move forward, debates continue on how best to balance these aspects to foster economic stability and growth. In 2009, a new system called Bitcoin emerged that could redefine the rules for money creation.
