The credibility of the monetary guardian

CNBC reports that August inflation data has placed Kevin Warsh at a crossroads: his own public warnings about rising prices now demand a response, yet hesitation — perhaps from political calculation, perhaps from simple irresolution — would call into question whether he commands the institution he is meant to lead. This is, at its root, not a technical question about basis points. It is a question about institutional honesty, and that question I understand very well.

I never knew a central bank in its modern form — the Federal Reserve as it now exists was not within my experience, and I will not pretend otherwise. But I did know the problem it is meant to solve. The value of money is a public good. When it is debased — whether by a prince clipping coins or by a sovereign printing beyond his means — it is the consumer, and above all the working person whose wages are fixed in nominal terms, who suffers first and longest. The merchant with warehoused goods can raise his price tomorrow; the laborer cannot raise his wage with the same speed.

The institutional insight that matters here is one I argued at length in The Wealth of Nations: a body entrusted with a public function must be constituted so that its private interest aligns with its public duty, or failing that alignment, must be disciplined by rules it cannot easily bend. A central bank whose governor fears the displeasure of the executive will shade his judgment toward the executive's comfort. That is not a monetary policy; it is a form of sycophancy with macroeconomic consequences.

CNBC frames Warsh's dilemma as a choice between "acting on his inflation warnings" and "risking new doubts about his control." I would reframe it: the doubt about control is already there the moment a governor's known convictions are suspected to bend under pressure. Markets — and here I speak of the collective judgment of innumerable buyers and sellers of bonds, wages, and goods — are not deceived for long. If inflation is indeed rising and the response is muted for reasons of political convenience, the expectation of further inflation becomes self-fulfilling. The merchant who believes prices will be higher next month raises them this month; the laborer who believes the same demands wages that anticipate it. The governor's hesitation thus produces the very condition he hoped to avoid.

This is precisely why I argued that certain public functions — justice, defense, and I would now add the maintenance of a sound currency — cannot be left to the logic of private advantage without institutional guardrails. A central bank independent in law but dependent in practice is no independence at all. The framework must be honest; the actors within it must then be held to the framework.

What is to be done? The institutional answer is straightforward, even if the political one is not: the mandate must be clear, the criteria for action must be public, and the governor must be seen to follow them regardless of the political weather. This is not rigidity — prudent judgment always has its place — but it is accountability. A governor who has stated publicly that inflation is a danger and then declines to act when the data confirms that danger owes the public an explanation that rises above convenience. If that explanation is not forthcoming, the institution itself is weakened, and a weakened institution is a cost borne by every person who holds a wage, a savings account, or a fixed contract. That cost falls, as costs of institutional failure almost always do, most heavily on those least able to absorb it.
