How Central Bank Reserve Creation Differs from Physical Money Printing

Article Quant Q&A · Author: VDT-QHH
Read the original

Summary

The document discusses whether a central bank literally prints money or creates electronic reserves through its balance sheet. The answer uses a simplified lending example: a central bank supplies newly created funds to a commercial bank, which lends to a customer, and later receives principal and interest as the loan is repaid. It presents the example as a way to distinguish reserve creation from the everyday image of printing physical currency.

The account also suggests that returned principal can be removed from circulation and that interest income may be injected into the economy. This is an informal illustration, not a full description of central-bank operations or the banking system. Its claims about repayment, reserve balances, economic growth, and inflation are simplified and should not be treated as a general monetary model; the document supplies no evidence or discussion of the institutional details that determine those outcomes.

Key ideas

  • Central banks can create electronic reserve balances, so money creation is not limited to printing physical notes.
  • The response illustrates reserve creation through a simplified central bank, commercial bank, and borrower lending chain.
  • It describes repayment as returning principal and interest to the central bank, with principal removed afterward.
  • The example is highly simplified and does not establish a general relationship between reserve creation, growth, and inflation.

# Ray Dalio's claim in central bank print money


# Ray Dalio's claim in central bank print money












i'm learning about the financial market to start my journey becoming a quant.

I'm reading a book written by Ray Dalio, in which, there is a part where he claims:

> The central bank doesn’t literally “print money.” In doing this, it essentially borrows reserves from commercial banks that it pays a very short-term interest rate on.

I doubt it myself because as far as I know, the central bank does literally print money by adding electronics number in their balance sheet. But the reputation of Ray Dalio makes me doubt myself.

Could you please tell me what are your thoughts on this? Many thanks for your help!

I don't know what you're reading, but probably what Ray Dalio is implying is that if the Central Bank were to simply do that, you'd get inflation on the amount printed. Instead, what happens is a bit different.

In very simple terms (and made up percentages):

- You go to a retail bank and ask for 100_000 to start a business

- Retail bank lends you that money at 10%

- Retail bank asks central bank for that money, which is lent at 1%

- Central bank creates 100_000 out of thin air and gives it to Retail Bank

- Some years into the business, you pay Retail Bank the 100_000 plus 10_000

- Retail Bank pays Central Bank the 100_000 + 1_000.

- Central Bank deletes the 100_000 created out of thin air but now has 1_000

Those 1_000 represent economic growth and can be injected into the economy by the central bank without inflation.
