To answer your question, let’s look at the Federal Reserve Balance Sheet. Here is a very simplified example:
Note: Numbers in millions of dollars
| Assets |
|
|
Liabilities |
|
| Gold |
9,000 |
|
Federal Reserve Notes |
1,000,000 |
| Treasury Securities |
2,000,000 |
|
Member Bank Reserve Deposits |
1,000,000 |
| Bank Premises |
1,000 |
|
|
|
| Other Assets |

|
|
|

20,000 |
|
|
|
Other Capital Accounts |
5,000 |
|
|
|
|
|
| Total |
2,050,000 |
|
Total |
2,050,000 |
Member banks are required to deposit with the Fed a minimum amount of their reserves. For the above example, the total of these reserves are labeled “Member Bank Reserve Deposits” at $1,000,000 million (highlighted in yellow).
Let’s say the Fed decides to increase the money supply by $2,000,000 million over a period of time, then through Open Market Operations, it would purchase $2,000,000 million of treasury securities on the private market.
This is reflected on the balance sheet is as follows:
| Assets |
|
|
Liabilities |
|
| Gold |
9,000 |
|
Federal Reserve Notes |
1,000,000 |
| Treasury Securities |
4,000,000 |

For the above example, the amount labeled “Treasury Securities” (highlighted in yellow) increases from $2,000,000 million to $4,000,000 million, an increase of $2,000,000 million. This be be done by purchasing treasury securities from private security dealers, who in return receives checks from the Fed.
Notice the total amounts for the assets and liabilities plus capital accounts (both highlighted in green) are not equal. Per accounting rules, both total amounts must be in balance, i.e. equal to each other.
The private security dealers take the Fed issued checks, and deposit them into their respective member banks.
The Fed, upon check settlement, credits the respective member bank’s reserve deposit at the Fed, as follows:
| Assets |
|
|
Liabilities |
|
| Gold |
9,000 |
|
Federal Reserve Notes |
1,000,000 |
| Treasury Securities |
4,000,000 |
|
Member Bank Reserve Deposits |
3,000,000 |
| Bank Premises |
1,000 |
|
|
|
| Other Assets |
40,000 |
|

5,000 |
|
|
|
|
|
| Total |
4,050,000 |
|
Total |
4,050,000 |
For the above example, the amount labeled “Member Bank Reserve Deposits” has increased from $1,000,000 million to $3,000,000 million, an increase of $2,000,000 million.
Notice the total for both the assets and liabilities plus capital accounts (highlighted in green) are now equal to each other.
To answer your question, the Fed writes a check against nothing, payable to a security dealer, who then deposits the check at a member bank. Then once the check settles, the Fed credits the amount to the member bank’s reserve account at the Fed.
But of course, this is all done electronically, so in reality, no paper check is actually issued. The Fed directly credits the account, electronically.
To be candid, this is how it’s done in theory. I am not completely sure what the actual steps are, but this should provide a general idea.
