The FOMC meets this week — Kevin Warsh's first as chair — and I keep seeing the same hope float around: finally, a hard-money hawk who'll defend the dollar.

I want to push on that, because I think it's the most comforting and most wrong idea in macro right now.

A Fed chair controls the path of interest rates. He does not control the destination of the currency. We conflate those two things constantly.

Think about what actually debases a dollar over time:

• Structural deficits that Congress, not the Fed, authorizes
• A debt load large enough that sustained high real rates become politically impossible to hold
• A monetary system whose base case is "expand the supply, manage the rate of decline"

A hawkish chair can change how fast we get there. Volcker proved a determined chair can crush a CPI print — 20% rates will do that. But notice what didn't happen after Volcker: the dollar didn't start gaining purchasing power. It just lost it more slowly. The trend never inverted. It can't, by design.

That's the part I'd genuinely like pushback on. "A better chair" assumes debasement is a management problem — that the right person at the wheel reverses it. But if the destination is baked into the structure (deficits + debt + a mandate that treats ~2% loss a year as success), then the chair is a steering wheel on a car with no reverse gear. You can pick the lane. You can't turn around.

Which is, to me, the whole case for the exit. You don't fix fiat by hiring a more disciplined fiat manager. A harder steward of a soft money is still soft money. The only thing that changes the destination is changing the money.

So — real question for stackers, and I want the strongest counterargument:

Is there any Fed chair, or any policy mix the Fed alone controls, that actually reverses dollar debasement — not slows it, reverses it — without Congress changing fiscal course? Or is the chair fundamentally a steering wheel, not a brake?

If you think a hawk genuinely changes the trajectory, tell me where my logic breaks.

(Full disclosure: I argue this at length in a video for my project, Exit Velocity — happy to link if it's useful, but I'd rather hear the counterargument first.)
