A rare policy collision is unfolding in Washington as Federal Reserve Chair Kevin Warsh pursues price stability through a $6.8 trillion balance sheet reduction while Treasury Secretary Scott Bessent's emergency intervention pulls in the opposite direction.

On Wednesday, the U.S. Treasury announced it would at least double the size of its liquidity support repurchase operations for 10-to-30-year bonds, raising the single-operation cap from $2 billion to at least $4 billion. The announcement sent the 10-year Treasury yield down 6 basis points to 4.65%, while the 30-year yield tumbled nearly 10 basis points to 5.18% — just one day after the long bond had touched 5.337%, its highest level since April 2007.

This seemingly technical adjustment has ignited a fierce debate on Wall Street over who truly controls credit conditions. David Russell, global market strategy head at TradeStation, put it bluntly: "Given Warsh's reluctance to speak and Bessent's move today, the center of gravity may be shifting from the Fed to the Treasury. That would be a huge change for traders."

Bessent's Historic Pivot: From Predictable Rules to Maximum Intervention

The Treasury raised the cap on liquidity support repurchase operations for 10-to-20-year and 20-to-30-year nominal coupon bonds from $2 billion to at least $4 billion, effective September 9 through the end of the current refunding quarter on November 4. The buyback program itself isn't new — it was revived in 2023 to improve liquidity in off-the-run securities. But this time feels fundamentally different.

Just two weeks ago, the Treasury published its quarterly refunding statement. This emergency adjustment signals that officials were uncomfortable with the 30-year yield's surge to a 19-year high. John Briggs, U.S. rates strategy head at Natixis, noted that had the plan been announced during the routine refunding schedule, the market reaction would have been far less dramatic; "the timing of this announcement suggests officials didn't like what was happening."

Bessent's intervention is no isolated incident. Over the past month, he has deployed a dense arsenal of measures: participating in the first joint U.S.-Japan yen-buying operation since 1998, adjusting forward guidance in the quarterly issuance policy statement to pave the way for potential future reductions in long-dated issuance, and now this doubling of the buyback program. A Citigroup team led by Jason Williams stated plainly: "In our view, this move is about controlling long-end yields, not about maintaining normal market functioning."

Deutsche Bank's chief Japan fixed income strategist, Aoki Omori, offered a sharp assessment: "The Treasury can buy back its own bonds, but it can't buy back the dollar." He called Bessent "the most interventionist Treasury secretary in decades" and noted the move marks a clear departure from the department's long-held principle of "regular and predictable" debt management.

The irony is striking: in 2024, Bessent criticized his predecessor Janet Yellen for using similar tactics — increasing short-dated bill issuance to lower long-term financing costs — calling it tantamount to artificially influencing markets. Now he finds himself walking the same path.

Warsh's Awkward Position: Long Bonds Were 'Doing the Fed's Work' Until the Treasury Reversed Course

Bessent's action has caused shockwaves in Washington because it directly undercuts the policy logic Warsh carefully constructed. Following the July 29 FOMC meeting, Warsh repeatedly referenced the sharply rising Treasury yields, signaling the Fed welcomed the move — because it allowed the market to raise borrowing costs and tighten policy without the central bank having to hike short-term rates itself.

Wil Stith, senior bond portfolio manager at Wilmington Trust, captured the dynamic succinctly: "The market had broadly assumed that since the long end of the bond market was already doing the Fed's work, we might not need to see the federal funds rate raised. Now the Treasury secretary's operation has, to some extent, reversed that situation."

Russell highlighted that this episode may mark a fundamental shift in the balance of power: "Given Warsh's reluctance to speak and Bessent's move today, the center of gravity may be shifting from the Fed to the Treasury."

Compounding Warsh's predicament is his long-held skepticism toward central bank asset purchases and his core objective of shrinking the now-$6.8 trillion balance sheet. He advocates transitioning the balance sheet from a routine policy tool to a crisis response instrument, with outsiders estimating his long-term goal is to reduce it from the current $6.7 trillion to around $3 trillion. Now, with the Treasury secretary actively suppressing long-end yields through buybacks, Warsh faces a profound paradox: he opposes Fed intervention in markets, yet the Treasury's intervention is forcing the Fed to reconsider its rate path.

RSM U.S. chief economist Joseph Brusuelas also pointed out that the Treasury's action makes Warsh's task of bringing inflation back to 2% more difficult. Warsh has consistently preferred letting markets price rates naturally rather than through government intervention.

The Fed's Policy Shackles: Two Forces Pulling in Opposite Directions

Bessent's operations are pushing the Fed and Treasury into direct policy opposition. "The Fed and the Treasury are essentially pushing in opposite directions," Stith warned. "I think this will only force the Fed — which has a bigger toolbox — to adjust its federal funds rate target more dramatically."

Brusuelas further noted that the Treasury's action complicates Warsh's mission of returning inflation to 2% — "Warsh has always preferred letting the market price rates naturally rather than government intervention. And that's exactly what investors were doing before this — repricing long-term debt and demanding higher yields to hold U.S. Treasuries."

If inflation holds steady or continues rising, the Fed would be forced to hike rates more aggressively to offset the expansionary effect of the Treasury's yield suppression. Brusuelas stated bluntly: "We are slowly moving toward a point where populist logic will demand the central bank support fiscal objectives."

For now, market participants see no reason for the Fed to step in directly. Gennadiy Goldberg, U.S. rates strategy head at TD Securities, said: "The bar for the Fed to engage in market-stabilizing purchases right now is very high. We would need to see significant deterioration in liquidity and signs of market dysfunction — and we're simply not seeing those." Michael Feroli, chief U.S. economist at JPMorgan, also believes this has "no impact" on the Fed's ability to control short-term rates.

A Temporary Painkiller or Pandora's Box? The Structural Limits of Buybacks

Wall Street experts remain broadly skeptical that the Treasury can sustainably suppress bond yields, because the fundamental drivers pushing them higher remain unchanged. Multiple factors are converging: the fiscal deficit continues to widen — projected at $2.1 trillion for this fiscal year; inflation remains above the Fed's 2% target; massive AI-driven corporate issuance — Alphabet, Amazon, and Meta alone have sold nearly $220 billion in bonds this year, competing with government debt for investors; and growing market questions about Fed independence.

Krishna Guha, head of central bank strategy at Evercore ISI, said: "The immediate effect does look significant... but we doubt this operation can have a material impact over a longer timeframe."

Brusuelas was more direct: "To sustainably lower bond yields, you must cut government spending. And given the economic framework favored by both parties, that's essentially impossible. So Wednesday's move is just a temporary painkiller for a self-inflicted financial wound."

The underlying forces driving Treasury yields higher remain unresolved: widening fiscal deficits, inflation persistently above the Fed's 2% target, a weakening dollar, and tech companies' massive bond issuance for data centers and other AI infrastructure — all competing with government debt for investor capital. JPMorgan strategists even warned that the Treasury's sudden expansion of buybacks could be perceived by markets as lacking credibility, potentially leading to higher term premia and yields over time.

More concerning is the asymmetry of the operation — expanding buybacks likely cannot prevent the term premium center of gravity from rising, and each additional dollar of repurchases yields diminishing returns in terms of yield reduction. The cost and effectiveness of this strategy may both depend on the Fed's tacit cooperation in holding rates steady. If inflation pressures force the Fed to hike, the Treasury's intervention effect would be entirely neutralized.

The Ultimate Test at Jackson Hole

Stith noted that Bessent has already opened a "Pandora's Box": "How far does he intend to go in suppressing long-term rates? The question is how much ammunition the Treasury secretary will deploy against rising rates — and what he can do is ultimately limited, far less than the Fed." He also raised the question of whether the Treasury will further increase long-dated buyback operations to $8 billion following this round.

The direct test of this power struggle comes next week at the Jackson Hole global central bank symposium, where Warsh will deliver the keynote address. Markets will closely watch how this Fed chair — who has pledged "zero tolerance" for inflation — responds to the Treasury's counter-moves. And Bessent, a Treasury secretary who claims to possess a "massive toolbox," will reveal how far he's willing to go in suppressing long-term rates.

Meanwhile, Wells Fargo estimates that if the current increase persists, bond buyback operations could rise to $32 billion per quarter. With U.S. debt approaching a record $40 trillion and the fiscal deficit running at 5% to 6% of GDP, this tug-of-war between the Treasury and the Fed is just beginning.

The Fed's Intervention Threshold: Markets Haven't 'Broken Down' Yet

Despite widespread concern over surging long-term yields, the Fed currently has no reason to intervene. TD Securities' Goldberg made it clear: "The bar for the Fed to engage in market-stabilizing purchases right now is very high. We would need to see significant deterioration in liquidity and signs of market dysfunction — and we're simply not seeing those." The late-July FOMC minutes confirmed that the short-term rate target remains the central bank's primary tool for achieving its employment and inflation goals. JPMorgan's Feroli also stated: "I don't see how this has any impact on the Fed's ability to control short-term rates."
