Monetary policy, demystified.
The Fed has four tools, one mandate with two halves, and a 9-to-18-month lag between pulling a lever and you feeling it. Here is the lever, and here is the feeling.
Monetary policy is a short menu. Four tools, used in different combinations depending on where inflation and unemployment are. The funds rate is the headline, the one everyone watches. The balance sheet is the quieter lever that moves long rates when the funds rate is already pinned. Reserve requirements exist but are effectively off. Forward guidance is the Fed telling you what it is going to do next, which moves markets before it moves rates. Read the table left to right and you have the whole playbook in one screen.
— Fed monetary policy tools
| Tool | How it works | Effect on inflation | Effect on growth | Recent use |
|---|---|---|---|---|
| Fed funds rate | Sets the overnight bank-to-bank lending rate | Direct, via demand | Direct, with a 9 to 18 month lag | 525 bps of hikes 2022-2023, cuts from late 2024 |
| QE / QT | Fed buys or sells Treasuries and MBS to move long rates and bank reserves | Diffuse, via asset prices and credit | Supports valuations, easier financial conditions | Balance sheet peaked 2022 at $9T; QT reduced to ~$6.8T by 2026 |
| Reserve requirements | Minimum share of deposits banks must hold | Theoretically large, practically dormant | Constrains lending capacity | Cut to 0% in March 2020, still there |
| Forward guidance | Fed publicly telegraphs the rate path via statements, SEP dots, and press conferences | Reshapes expectations before any rate move | Moves long rates and financial conditions today | 'Higher for longer' in 2023; 'data dependent' 2024-2025 |
— Dovish vs hawkish
Dovish = cares more about jobs than inflation right now. Hawkish = cares more about inflation than jobs right now.
The labels are about priorities, not personalities. The Fed has a two-part mandate, stable prices and maximum employment, and those two halves pull in opposite directions most of the time. A dove is voting, this meeting, for the employment side. A hawk is voting, this meeting, for the inflation side. Same person, different meeting, different label.
The market reads every Fed communication as a tilt on that dial. Dovish surprise, yields fall and stocks rally. Hawkish surprise, yields rise and the rate-sensitive parts of the S&P get hit. Strategists will tell you Powell was dovish or Waller was hawkish as if it were a fixed trait. It is not. It is a read on which half of the mandate the voter thinks is under more pressure this quarter.
Which is why you can have a 'dovish hike,' where the Fed raises rates but signals it is the last one, and the bond market rallies anyway. The direction of the move matters less than what it implies about the next three. Forward guidance is the whole ballgame.
