Quantitative easing vs. tightening

Why the balance sheet became a policy tool

When the policy rate is already near zero, the Committee cannot cut it further to loosen conditions. Buying longer-dated assets is the alternative it chose: it bids up their price, pushes down their yield, and lowers borrowing costs at maturities the short rate does not reach directly.

That is not an emergency of nature. The short rate is at the floor because earlier decisions put it there. Quantitative easing is what comes next when the Committee wants still easier money and the overnight rate has no more room.

QE, mechanically

The Fed buys Treasury securities and agency mortgage-backed securities from dealers, and pays with newly created reserve balances. Both sides of its balance sheet grow: securities on the asset side, reserves owed to banks on the liability side.

That is money creation. Coverage often walks it back — reserves are not dollar bills; banks may park them; the “money multiplier” is not what a textbook drew. All of that can be true in a given month. None of it undoes the decision. The central bank chose the size of the balance sheet and paid by creating the corresponding liabilities. Whether those reserves sit parked or finance spending later, the stock was enlarged on purpose.

Friedman drew the line that still applies: government spending financed by creating money is inflationary; financed by taxes or by borrowing from the public, it is not, by itself. QE is the creating-money half of that line, applied to whatever paper the Fed is buying.

See what causes inflation for how that stock shows up, later, in the price level.

QT, mechanically

Quantitative tightening is the reverse, and it is usually less active than the name. The Fed holds securities that mature on a schedule. Rather than reinvesting the proceeds, it allows a capped amount to roll off each month. The balance sheet shrinks and no asset is sold.

Two things follow. First, “the Fed is selling bonds” is usually wrong as a description. Second, the pace is bounded by what actually matures — if less than the cap matures in a month, the reduction is smaller, regardless of intent. Tightening that can only go as fast as the calendar is a slower instrument than the easing that created the stock.

The reserves that disappear were never currency in a wallet. They are still a withdrawal of base money. QT is the Committee choosing a smaller balance sheet, just as QE was choosing a larger one.

Who pays

When QE suppresses long yields, anyone who must live on the return from a safe bond — retirees, pension funds, insurance accounts — is paid less. When the extra money later shows up as a higher price level, households on fixed incomes and anyone holding cash pay again. Those are transfers, not residuals.

QT works in the other direction: yields have more room to rise, and new borrowers pay more. Existing holders of long bonds can lose on price. There is no setting of the balance sheet that is free.

Open market operations are the daily plumbing that holds the funds rate in its range. QE and QT are the same desk, in size, used as a second policy instrument.

Reading the releases

The weekly H.4.1 release is the primary record of the balance sheet, published every Thursday. Its headline line is total assets; the composition beneath it shows which holdings are running off and how fast. The figure on this page is the stamped stock. A story that treats the balance sheet as background colour, and the policy rate as the only decision, is leaving the larger lever out.

How to read the coverage

• “Printing money” — crude, and in one respect exact: the Fed pays by creating reserves. Ask what happened to the stock, not whether anyone handed out banknotes.
• “The Fed is selling bonds” — usually false under QT. Look at runoff caps and what actually matured.
• “QE is just swapping assets” — the private holder has a Treasury; the banking system has new reserves. The swap enlarges base money.
• “The balance sheet is a technical residual” — it is a chosen stock. The H.4.1 line is the record of that choice.
