The Fed's rate-cut era is over. Markets now debate a hike

The man in the headline has already left. Jerome Powell, who as chairman of the Federal Reserve spent 2025 steering interest rates down, ended his term in May; the Senate confirmed Kevin Warsh, a long-time conservative critic of the Powell order, on a 54-45 vote, and he was sworn in on May 22nd. It is Warsh who gives the keynote address at the Jackson Hole symposium on Friday, and the market he faces has already done the repricing the speech is supposed to cause — in the opposite direction from the cheap-money story that opened 2026.

That reversal is the real storm, and it did not begin with a speech. The Fed's policy rate has not changed all year: it sits at 3.50-3.75%, the range reached after a year of cuts in 2025, and has been held there for five consecutive meetings. What has changed is what investors expect the next move to be. In January markets assumed the direction of travel was still down, and as late as spring respectable banks were pencilling cuts into their 2026 forecasts. By late August the assumption had inverted. After July's inflation report — personal-consumption-expenditure prices up 3.7% on a year earlier, or 3.3% excluding food and energy, nearly double the 2% target — futures priced a rate rise at the September 15-16 meeting at 44%, up from about a third before the data. Traders place strong odds on at least one increase before the year is out; the remaining cut forecasts have been pushed into 2027.

The cause was not a central banker but a war. Conflict with Iran, which brought the Strait of Hormuz close to closure, delivered an oil shock that pushed American inflation back up: headline PCE reached 4.1% in May, eased in June as crude slipped, then stuck at 3.7% in July. The OECD now expects the conflict to slow world growth and keep inflation elevated into 2027. More consequential than any single month is the arithmetic of expectations: inflation has run above the Fed's 2% target for more than five years, which is precisely the condition that convinces households and firms that above-target prices are permanent rather than temporary.

It is against that background that the opening day of the symposium sounded less like the polite seminar of legend and more like a show of force. Three regional Fed presidents argued, in effect, that the current rate is not high enough. "I don't know what we're restricting currently with the rate policy that we're at today," said Jeffrey Schmid of the Kansas City Fed. "I believe now is the time to act," said Beth Hammack of Cleveland, citing workers she had met in Erie, Pennsylvania. Austan Goolsbee of Chicago gave the operative warning: his biggest short-run fear is that "inflation is not under control."

The technical case is that the neutral rate — the setting that neither stimulates nor restrains — has risen, to perhaps 3.5-4%, as government deficits, an AI investment boom and post-pandemic habits have all pushed it up. If neutral sits that high, a policy rate of 3.50-3.75% is not squeezing the economy; it is, at best, holding it in place. That is a genuinely harder situation than the Fed has faced in years, because it means the obvious remedy for sticky inflation is not patience but an actual increase.

Enter the new chairman's second contribution to the storm: he has abolished the Fed's most important piece of machinery. For a decade, the Powell and Yellen Feds told the market roughly what they intended to do, far in advance. Warsh has refused. "Market participants are learning to play the ball and not the referee," he said in July; his Jackson Hole speech is expected to "frame the big questions" rather than answer them. Removing the anchor has a mechanical effect. When the central bank will not say what it will do, every inflation print becomes a coin toss, and bondholders demand more compensation for guessing. That is one reason the long end of the Treasury market — not the policy rate, which has been idle all year — has done the storm's work. The 30-year yield, near 5.2%, sits at a 19-year high; the 10-year hovers around 4.7%, close to the top of its recent range; 30-year mortgage rates have been pushed to about 6.75%.

The second force pushing long yields up is the state of the government's finances, which are deteriorating in plain view: publicly held debt of $32.2 trillion, a deficit of $2.1 trillion this year, and interest payments absorbing roughly 15% of federal spending. And here the storm takes a stranger turn. Treasury Secretary Scott Bessent, alarmed that yields had risen about 70 basis points since the war began, responded not by letting the market clear but by intervening in it. In mid-August the Treasury said it would roughly double its monthly buybacks of long-dated bonds, to at least $4 billion, possibly funding the purchases from the $1 trillion pile in its bank account. Yields are "not reflecting the underlying fundamentals," Bessent declared.

The sums are trivial next to a $32 trillion debt; $4 billion a month cannot move a market that size by force. The significance is institutional. The fiscal authority is now openly working to suppress the very yields that the monetary authority's inflation fight implies, and the objections have come from every direction. The Treasury's own advisory committee warns that the move flouts its guidance on the maturity mix — short-term bills already make up 22.2% of the debt, above the committee's recommended ceiling. Stanley Druckenmiller, who made his fortune betting on bond-market reality, attacked the intervention. The dollar fell sharply when the announcement landed, and Bank of America, which calls the whole episode a "key risk event," says the greenback is "on the back foot" and vulnerable to an extended sell-off if Warsh disappoints. The bond-market rally the announcement produced was brief; yields resumed their climb within days.

The deeper point is that debt management has begun to move into territory that used to belong to monetary policy. "We're slowly moving to the point where the logic of populism is going to insist that the central bank support fiscal objectives," says Joseph Brusuelas of RSM. That is not a neutral development. President Trump, who installed Warsh, wants lower rates to cut the cost of financing his administration's borrowing; Bessent's buybacks serve the same end through the back door. Goolsbee offered the warning from the podium: where political authorities interfere with the central bank, he said, "inflation comes roaring back."

So what happens at the September 15-16 meeting? The committee is genuinely split, and that is the honest answer to the question every rate-sensitive investor is asking. Three members — Hammack, Kashkari and Logan — voted for a hike in July; four more votes would hand the hawks a majority. Warsh has refused to say where he stands, and the banks are as divided as the committee: Morgan Stanley and Stifel expect a speech that offers markets little, while Bank of America warns that if Warsh does not damp the long end, yields could jump toward 5.5%. If that happened, the pain would spread from Treasuries to mortgages, to housing, and to the long-duration growth stocks whose entire value rests on distant earnings discounted at low rates.

The storm is therefore not a weather event but a question of whether a shock becomes a regime. The case for a fade is real: energy prices have risen far less than after Russia's invasion of Ukraine, and inflation already cooled between May and June before stalling. If the oil effect passes and price pressures roll over, markets will price this autumn's hikes back out, the bond market will calm, and the 10-year may never test 5%. The case for persistence is equally real: the longer inflation sits near 4%, the more it seeps into rents, car prices, wages and expectations, and the more the Fed must choose between hiking into a cooling economy and watching its credibility dissolve.

Either way, the cheap-money assumption that underpinned the last decade of portfolios is gone, and it was killed by a war and a fiscal intervention, not by any single speech. The deeper lesson of this Jackson Hole may be institutional. A central bank that refuses to guide, a treasury that intervenes, a bond market left to do the thinking on its own — each improvisation is reasonable in isolation, and together they are why the 30-year yield sits at levels not seen since before the financial crisis while the policy rate has not moved in a year. The referee has stopped signalling. The players, on the evidence, are heading for a collision.
