Most of the arguments about Federal Reserve independence being made this month are really arguments about a two-paragraph press release issued on 4 March 1951. The man now chairing the Fed spent much of 2025 arguing that document needs rewriting. Understanding what it actually said is the difference between following the current dispute and guessing at it.

Short answer: the day the Fed stopped capping bond yields
Short answer: From the Second World War until 1951, the Federal Reserve held Treasury yields at fixed levels — roughly three-eighths of a percent on bills and a ceiling of 2.5% on long bonds — by buying whatever quantity of government debt was required to defend those levels. Monetary policy was therefore subordinate to debt management: the Fed could not tighten without breaking the peg. The Treasury-Fed Accord of March 1951 ended that arrangement and established that the Fed sets policy independently while the Treasury manages the debt. Every modern claim about central bank independence in the United States traces back to it.
What the peg actually did to the economy
A yield ceiling sounds technical and reads as harmless. Its consequence is not. If the central bank commits to keeping a bond yield below a set level, it surrenders control of its own balance sheet: whenever private demand is insufficient to hold yields down, the Fed must create reserves to buy the difference. The size of the money supply becomes a residual of how much the Treasury chooses to borrow.
That arrangement is tolerable during a war, when the priority is financing one, and intolerable afterwards. The Korean War made the point unavoidable. Consumer prices rose sharply through 1950 and into 1951 while the Fed remained contractually unable to raise rates in response. Officials were, in the phrase used at the time, an engine of inflation with no throttle.
| Before the Accord (1942-51) | After the Accord | |
|---|---|---|
| Who sets long yields | Fed, by decree, at 2.5% ceiling | The market |
| Fed balance sheet size | Determined by Treasury issuance | Determined by policy objectives |
| Response to inflation | Structurally blocked | Available |
| Treasury’s role | Effectively directs monetary policy | Manages debt issuance only |
How it was resolved, and why the method matters
The confrontation was not decorous. President Truman summoned the entire Federal Open Market Committee to the White House in January 1951 — the only time that has happened — and afterwards the administration issued a statement implying the Fed had agreed to maintain the peg. Marriner Eccles, a former Fed chair still serving as a governor, responded by releasing the Fed’s own memorandum of the meeting to the press, which showed no such agreement had been given.
The public contradiction forced a negotiation, and the negotiation produced the Accord. Its operative language committed both institutions to “minimize monetization of the public debt.” Thomas McCabe resigned as Fed chair shortly afterwards. His replacement was William McChesney Martin, who had negotiated the agreement on the Treasury’s side and was expected to be compliant. He then ran the Fed for nineteen years and became the most quoted defender of its independence in its history.
The lesson practitioners draw from the episode is not that independence was granted. It is that independence was taken, publicly and at some institutional cost, and that the people who took it expected to be replaced for doing so.
What Warsh proposed, in his own framing
In an April 2025 speech, before his nomination, Warsh said the spirit of the 1951 accord “is at odds with recent practice.” In July 2025 he was more explicit: “We need a new Treasury-Fed accord, like we did in 1951 after another period where we built up our nation’s debt and we were stuck with a central bank that was working at cross purposes with the Treasury.”
The substance behind the rhetoric concerns the balance sheet, which stood around $6.6 trillion after a decade of asset purchases. Warsh’s stated objective is a materially smaller Fed footprint in the bond market. The mechanism he floated would give the Treasury a greater say over major balance sheet adjustments, on the reasoning that large-scale asset purchases are a form of debt management and debt management is the Treasury’s job.
Read one way, that is a proposal to restore the 1951 division of labour rather than to overturn it: the Fed shrinks out of a market it should never have occupied so heavily, and stops doing something adjacent to fiscal policy. Read another way, it hands the Treasury influence over the size of the central bank’s balance sheet, which is the precise variable the 1951 negotiation was fought over. Both readings follow from the same proposal, which is why the reaction to it has been genuinely divided rather than performatively so.
| The two readings | Claim | Weakness of that claim |
|---|---|---|
| Restoration | QE blurred the line; shrinking the balance sheet sharpens it again | Treasury sign-off on Fed balance sheet decisions is not what 1951 established |
| Erosion | Any Treasury veto over the balance sheet subordinates policy to financing | The Fed already coordinates with Treasury operationally without losing independence |
Why the market reaction has been muted so far
Analysts at Bank of America concluded in February that a new accord would have minimal direct market impact, and the price action since has broadly supported that. The reason is that an accord is a statement of principle, not an instrument. The 1951 document changed behaviour because it removed a specific numerical commitment — the 2.5% ceiling — that traders could see and trade against. There is no equivalent number on the table now.
What would change the market’s view is any language that looks like a target for a yield or a quantity. The distinction between coordination and subordination is not philosophical when it reaches the tape; it is whether someone has committed to buying at a price.
What this article does not conclude
Nothing here judges whether a revised accord would be good policy, nor predicts whether one will be negotiated. No formal proposal has been published; the public record consists of speeches, interviews and secondary commentary on them, and the gap between a speech and a signed institutional agreement is wide enough to hold most of the disagreement about what it would mean.
The 1951 Accord itself is short and worth reading in the original — it is reproduced in full in the Federal Reserve’s historical archives, and the Brookings Institution maintains an accessible explainer of the surrounding events. Balance sheet figures come from the Fed’s weekly H.4.1 release and change every Thursday.
