Major investors are raising alarms that Treasury Secretary Scott Bessent's recent bond market moves are working against the Federal Reserve's fight against inflation, just as Fed Chair Kevin Warsh prepares to address the Jackson Hole symposium. The warning comes after Bessent unexpectedly announced last week that the Treasury would "at least double" its long-term bond repurchase program, a decision that drew widespread criticism from Wall Street.

Investors argue the initiative could undermine the Treasury's own credibility while also hampering the Fed's ability to curb inflation, which has resurfaced this year. The move, aimed at supporting the $32 trillion Treasury market after long-term borrowing costs climbed to 19-year highs, has also intensified pressure on Warsh, who is scheduled to speak Friday at the Kansas City Federal Reserve's Jackson Hole economic conference in Wyoming.

"I have a very negative view of the Treasury's logic and its haphazard intervention in the market. I believe this is a self-defeating strategy that will ultimately backfire," said Greg Peters, co-chief investment officer of credit at Prudential. "The market is looking to Warsh for signals, but I'm not sure what he can do under these circumstances."

Lisa Shalett, chief investment officer at Morgan Stanley Wealth Management, added that intervening in the Treasury market merely because of dissatisfaction with rising yields "isn't a defensible reason — it's purely discretionary." She noted, "No one wants to see a Treasury that acts unpredictably and arbitrarily." If Bessent continues attempting to influence yields in the world's most important bond market, "it would be an admission that Washington is deeply concerned about debt sustainability."

Bessent's unexpected intervention has heaped pressure on the Fed chair, with markets hoping he will ease investor concerns over fiscal and economic risks. The Trump administration's military actions in Iran have already pushed up costs for U.S. consumers and businesses. As Warsh heads to Jackson Hole, he faces pressure from both markets and some Fed rate-setting committee members to clarify what conditions would warrant a rate hike to bring inflation back to the Fed's 2% target. The latest U.S. inflation reading stands at 3.7%.

Bessent's expanded bond repurchase program is designed to lower long-term borrowing costs, which have surged in recent months due to inflation worries, increased government debt issuance, and heavy financing for the artificial intelligence boom. Warsh and Bessent, both protégés of hedge fund titan Stanley Druckenmiller, meet regularly and are widely seen as having a cordial personal relationship. But investors and economists point out that the policy priorities and strategic approaches of the Fed and Treasury are increasingly diverging.

Druckenmiller publicly stated this week that the plan to at least quadruple long-term bond repurchases to $4 billion was "a mistake." He wrote, "This is not liquidity management — it's outright price manipulation, and its negative effects far exceed what the $4 billion figure suggests." The Treasury's intervention has had limited actual impact on bond yields so far. However, if Bessent's efforts prove successful, they would push down mortgage rates and other financing costs, thereby stimulating the economy — at a time when several Fed officials have indicated the central bank should be doing the opposite by raising rates to contain inflation.

Three members of the Federal Open Market Committee voted for a rate hike at the July meeting, and other regional Fed presidents have since voiced support for a 25-basis-point increase in borrowing costs. Krishna Guha, vice chairman of Evercore ISI, said the Treasury's move not only unsettles investor sentiment but "also makes the FOMC uneasy." After implementing the intervention, Bessent asserted that rising U.S. government borrowing costs do not "reflect the true state of economic fundamentals."

In stark contrast, Warsh has emphasized that investors should rely more on economic data and market prices rather than waiting for so-called forward guidance from central bank officials on the trajectory of U.S. borrowing costs. Last month, the Fed chair stated that higher Treasury yields reflect objective economic realities, meaning U.S. borrowing costs should rightfully rise, adding that during his tenure the Fed has "strived not to interfere with market signals."

Guha noted, "Warsh's core stance is hard to reconcile with what the Treasury is currently doing. If the Treasury secretary publicly declares that market prices are wrong and directly intervenes in the bond market, it becomes very difficult for Warsh to call on the bond market to rely on its own price-discovery mechanism."

Market participants widely expect Warsh to use his Jackson Hole address to explain the policy logic behind his significant reduction of forward guidance and to demonstrate that, over more than five years, he has the ability to steer inflation toward the Fed's 2% target. Scott Barnard, fixed income portfolio manager at Westwood Capital, said Warsh's abandonment of forward guidance, combined with Bessent's efforts to suppress long-term yields, creates the impression that the Fed and Treasury are "moving in opposite directions."

With November's midterm elections approaching, the Trump administration is eager to lower borrowing costs. There are concerns that if Bessent's yield-management attempts continue to show little effect, the Fed could also face pressure to intervene in markets. Jason Furman, a Harvard professor who served as chairman of the White House Council of Economic Advisers under the Obama administration, warned, "If the Fed has to take government debt management into account when setting monetary policy, there's a risk of fiscal dominance."
