To truly understand QE and QT, you have to look under the hood of the Federal Reserve itself. The Fed’s balance sheet is the ultimate "dashboard" for its operations. It is a weekly report (known as the H.4.1 report) that shows exactly what the Fed owns and what it owes .

The Asset Side: What the Fed Owns

An asset is anything of value that the Fed has purchased. Because the Fed can create its own currency to buy things, its "purchasing power" is theoretically unlimited, constrained only by political will and the risk of inflation .

1. U.S. Treasury Securities

This is the largest category of assets. These are essentially loans made to the U.S. government.

Treasury Bills: Short-term debt (maturities of 1 year or less) .
Treasury Notes: Medium-term debt (2 to 10 years) .
Treasury Bonds: Long-term debt (more than 10 years) .
As of early 2025, the Fed held over $4.2 trillion in these securities .

2. Mortgage-Backed Securities (MBS)

These are "bundles" of home mortgages. When the Fed buys these, it is providing liquidity directly to the housing market. By 2025, the Fed owned roughly $2.2 trillion in MBS .

3. Loans to Banks

The Fed also acts as a "bank for banks." It provides short-term loans to commercial banks through the "discount window" or "repo market" to ensure they have enough cash to meet their daily obligations .

The Liability Side: What the Fed Owes

In the world of central banking, "money" is actually a liability. This can be confusing for beginners, but think of it this way: a dollar bill in your pocket is a "promise" from the Fed.

1. Currency in Circulation

Every physical dollar bill in the world is technically a liability of the Federal Reserve. As of 2025, there were about $2.3 trillion in Federal Reserve notes (cash) circulating globally .

2. Bank Reserves

This is the most important liability for QE and QT. When the Fed buys a bond from a bank, it doesn't give the bank cash; it increases the bank's "reserve balance" at the Fed. These are digital deposits that banks keep at the Fed, similar to how you keep money in a checking account. These reserves reached over $3.3 trillion by 2025 .

3. Reverse Repurchase Agreements (Reverse Repos)

This is a tool the Fed uses to "soak up" extra cash from the system. The Fed "borrows" money from banks and money market funds overnight, giving them Treasury bonds as collateral. This helps the Fed keep interest rates from falling too low .

How the Fed Funds Itself

A common question is: "Does the Fed use my tax dollars?" The answer is no.
The Federal Reserve is self-funding. It pays its operating expenses using the interest it earns on the trillions of dollars of Treasury bonds and MBS it owns . In fact, the Fed usually makes so much profit that it sends billions of dollars back to the U.S. Treasury every year .

Indicators the Fed Watches

The Fed doesn't just decide to do QE or QT on a whim. They watch a specific set of "dashboard gauges" to decide when to act .

Consumer Price Index (CPI): A lagging indicator that measures the retail price of a basket of goods. If CPI is too high, the Fed might start QT .
Producer Price Index (PPI): A leading indicator that measures the costs for businesses. If PPI rises, it usually means CPI will rise a few months later, giving the Fed an early warning .
The Yield Curve: A leading indicator that compares short-term and long-term interest rates. If the curve "inverts" (short-term rates become higher than long-term rates), it often signals a recession is coming, which might prompt the Fed to start QE .
Personal Consumption Expenditures (PCE): The Fed’s preferred measure of inflation. They target a 2% annual increase in the PCE .

Assets (What the Fed Owns)	Liabilities (What the Fed Owes)
Treasury Securities: Loans to the government .	Currency: Physical cash in circulation .
Mortgage-Backed Securities: Support for housing .	Bank Reserves: Digital cash held by banks .
Loans to Banks: Emergency liquidity .	Reverse Repos: Temporary cash "soaking" .

Frequently Asked Questions about the Balance Sheet

Q: Who owns the Federal Reserve?
A: It’s a mix of public and private. The Board of Governors is a government agency, but the 12 regional Federal Reserve Banks are set up like private corporations owned by their member commercial banks .

Q: What happens if the Fed's balance sheet gets too big?
A: A massive balance sheet can lead to "market distortions." It means the Fed is a dominant player in the bond market, which can make it harder for private investors to determine the "true" price of bonds .

Q: Does the Fed ever "go broke"?
A: No. Because the Fed can create its own currency, it cannot run out of money. However, if it creates too much money, the value of that money (its purchasing power) can drop significantly .

Q: How often does the Fed report its balance sheet?
A: Every Thursday, the Fed releases the H.4.1 report, which provides a snapshot of the balance sheet as of the previous Wednesday. Investors watch this closely to see if the Fed is actually following through on its QT or QE promises .
