Two referees, one market: America's fight over the price of its own debt

TWO REFEREES, ONE MARKET. That is where the American government now finds itself, and the contest is over the price of its own money. On August 19th the Treasury said it would at least double the amount of long-term debt it buys back, in a transparent attempt to drive long-term yields down. Late last month the Federal Reserve's policy committee had held its rate steady in a 9-3 vote, with three officials pressing to raise against inflation that will not die. Two arms of the same government, pulling in opposite directions. Gregory Daco, chief economist at EY-Parthenon, calls it a government with "two referees". Whether rates end up higher or lower matters less than the question the spectacle raises: who, in this arrangement, is allowed to set them?

Scott Bessent, the treasury secretary, presents his operation as housekeeping. The Treasury will at least double the maximum size of its buying of ten-, twenty- and thirty-year bonds, from $2bn to at least $4bn, between September 9th and November 4th. Its stated purpose is liquidity: buying older, less actively traded "off-the-run" securities so that big institutional balance sheets free up room for newer, more liquid issues and stop pushing yields higher. The timing is not neutral. The thirty-year yield had just touched a nineteen-year high above 5.3%, and the ten-year had pushed above 4.7%, its highest since 2007, lifted by the oil shock from the war with Iran, by the borrowing needs of artificial-intelligence data centres and by the Treasury's own voracious financing. The announcement shaved as much as ten basis points off the thirty-year, to about 5.2%, and brought the ten-year to roughly 4.65%. Within a day most of the relief had gone.

The giveaway is in the funding. The Treasury will not replace the bonds it retires with more long-term debt. It will pay for the purchases by selling short-term bills, which already account for 22.2% of outstanding federal debt, above the 20% ceiling recommended by the Treasury Borrowing Advisory Committee, the market's own advisory body. A debt manager that quietly converts long-term bonds into short-term bills is making a bet that short rates stay low, and handing the taxpayer the risk of rolling the debt over. That risk is not abstract: roughly a third of marketable federal debt matures each year, so a large slice of the balance sheet is constantly being repriced. If rates rise, the bill arrives immediately rather than decades from now.

Against this, Kevin Warsh, who took the Fed's helm in May, runs a deliberately contrary regime. In July the committee left its policy rate at 3.5-3.75% for a fifth consecutive meeting, citing "somewhat tighter financial conditions" arriving through higher market-based rates — a polite way of saying that the long end was doing the Fed's tightening for it. Mr Warsh has withheld forward guidance, telling markets to "play the ball, not the referee", and says he wants the bond market to take the wheel in setting the price of money. In his view high long-term yields are not a nuisance but the main channel through which tight policy reaches the economy, sparing the Fed the need to raise short rates and disciplining a Congress that overspends. He has promoted shrinking the central bank's footprint, a "reverse Operation Twist" in which maturing holdings are reinvested in short-dated debt, which would push long-term yields higher still. Every dollar the Treasury spends pulling long yields down, in other words, is a dollar of the tightening Mr Warsh has chosen not to deliver.

The reversal of positions is dizzying. Mr Bessent spent 2024 denouncing his predecessor, Janet Yellen, for loading the federal balance sheet with short-term bills to disguise the cost of overspending, and last year criticised the Fed's bond-buying for holding yields down. Now he runs a shrunken version of both policies at once. When a finance ministry starts buying its own long-dated debt in order to steer the level of yields, it has left the province of debt management for the murkier territory of monetary policy by other means. George Saravelos of Deutsche Bank calls the approach "a soft form of financial repression". It is a technique with a long and dishonourable pedigree; the bill always arrives.

Would that the trick worked. The sums are tiny against a market of roughly $31trn of marketable federal debt. Barclays estimates the expanded buying adds about $64bn a year, some 15% of the annual supply of twenty- and thirty-year bonds; Krishna Guha of Evercore ISI dismisses it as "a very small-scale Operation Twist" that "changes almost nothing" about the fundamentals — and the fundamentals are the problem. The term premium, the extra return investors demand for holding long-dated debt, is not a liquidity glitch. It is the price of arithmetic: a budget deficit of $2.1trn this year, net interest payments of $963bn in the first ten months of the fiscal year, a gross federal debt that has passed $40trn. Buying a sliver of the supply addresses none of this. It treats the symptom of fiscal incontinence while the disease flourishes.

The side effects are worse. By leaning on the long end, the Treasury mutes the market's own disciplining mechanism just when inflation is stubborn. Brij Khurana of Wellington Management argues that the longer the state holds long-term yields down, the more the Fed may eventually have to raise short rates; and, because so much debt has been shifted into bills, those hikes hit the budget almost at once. The dollar slipped nearly 0.8% against a basket of currencies, importing inflation through costlier imports. Officials have even leaned on the currency market, supporting the yen to keep Japanese investors from dumping Treasuries and worsening the rout. A government that set out to borrow more cheaply therefore ends up with higher short rates, a weaker currency, stickier inflation and a debt pile that reprices faster. That is not clever shopkeeping. It is the anatomy of fiscal dominance, the point at which a finance ministry stops trying to be creditworthy and starts trying to set its own terms.

None of this is a failure of co-ordination, though Mr Bessent offers that defence, insisting there is "no connection" between his operations and the Fed's decisions. There is a connection; it simply runs through the market, and it exists precisely because the Treasury now occupies ground where the rate-setter is supposed to stand. The neatest charter for the division of labour was written by the Treasury Borrowing Advisory Committee, which warned that buybacks should serve liquidity, not reshape the debt profile: reshaping is the job of issuance, on transparent schedules. A restored boundary would look like this. Buybacks confined to genuine off-the-run liquidity, their funding disclosed before the first operation. The Fed left to be the referee. And, above all, a government that borrows less. The Congressional Budget Office projects debt held by the public climbing from about 99% of GDP to roughly 120% by 2036. There is no exotic instrument that converts that trajectory into cheap money. The only durable way for a government that wants lower borrowing costs to get them is to shrink the deficit that sets them.

The signals, then, were never truly mixed. The Treasury and the Fed know exactly where they would like rates to end; they disagree, violently, about who should do the orchestrating. The real message of the past week is that the question is no longer whether American interest rates will rise or fall, but whether the world's benchmark safe asset is priced by an independent central bank and a functioning market — or by a finance ministry that believes its own money. Markets forgive many fiscal sins. The repurchase of one's own debt to deny the price is not among them. A government that wants cheap money should earn it, by behaving like a borrower whose word is good. That means fixing the deficit, not repressing the market.
