Goldman: Bessent's $4B Buyback Doubling Offers 20-40bp Relief, Not a Cure

Bessent doubled the long-end buyback cap to $4 billion per operation, but Goldman sees only temporary relief.

The Treasury doubled its long-bond buyback cap to $4 billion per operation, but Goldman Sachs sees only 20-40 basis points of temporary relief before structural fiscal forces reassert control over long-end yields.

"Operation Twist can affect term premium but cannot eliminate it. Such operations can change the path but rarely change the destination," said Vitali Meschoulam, macro strategist at Goldman Sachs.

The 30-year yield fell roughly 10 basis points Wednesday after the announcement, retreating from a 19-year high of 5.33 percent. By Thursday, the 10-year yield had climbed 3 basis points to 4.684 percent, essentially erasing the initial relief. The expanded program, effective Sept. 9 through Nov. 4, targets 10- to 30-year maturities and could repurchase close to 30 percent of projected annual issuance in that bucket — yet only about 2.4 percent of outstanding market debt.

The intervention addresses a symptom, not the cause. U.S. federal debt crossed $40 trillion this week, the fiscal deficit runs near 6 percent of GDP — double Bessent's stated 3 percent target — and AI infrastructure buildout is absorbing unprecedented capital. Goldman argues that until growth deteriorates, inflation decisively falls, or fiscal conditions improve, investors will keep demanding compensation for holding duration.

Buyback Scale Reaches 30% of Issuance, 2.4% of Outstanding Debt

The buyback expansion is the most aggressive market intervention since Bessent took office, and its immediate effect was unmistakable. The 30-year yield dropped from 5.33 percent to around 5.20 percent, while all three major U.S. stock indexes snapped losing streaks — the Dow rose 0.22 percent to 53,463.05, the S&P 500 gained 0.21 percent to 7,707.98, and the Nasdaq added 0.16 percent to 26,331.09.

But the scale is modest relative to the market it targets. Natixis estimates the expanded buybacks could reach close to 30 percent of projected issuance in the 10- to 30-year bucket, but that represents only about 2.4 percent of outstanding market debt in those maturities. John Briggs, head of U.S. rates strategy at Natixis, said the timing of the announcement made clear officials were unhappy with prevailing conditions, even if the Treasury ultimately does not buy bonds in large volumes.

The dollar has absorbed much of the pressure. With short rates anchored by Fed policy and long rates under intervention, the market's stress has shifted to the currency, which weakened following the announcement. The friction between Treasury's long-end management and the Fed's ongoing balance sheet reduction will be a key variable heading into the Jackson Hole symposium. Fed minutes from July showed three committee members voted for a rate hike, highlighting the divergence within the FOMC.

When Intervention Worked: 1961 Twist, 2011 MEP, Japan's YCC

Goldman's analysis draws on historical precedents where yield-curve interventions succeeded — and where they failed. The 1961 Operation Twist and the 2011 Fed Maturity Extension Program each delivered 10-20 basis points of long-end compression, but both operated when inflation was benign and growth was weak, with markets already inclined toward lower rates.

Japan's yield curve control was the most successful long-end suppression in history, but its conditions were exceptional: persistent deflation, abundant domestic savings, and broad investor acceptance of policy-set equilibrium yields. Once inflation returned, the cost of maintaining the cap escalated until the policy collapsed. Australia's yield target met a similar fate when markets judged that inflation and growth had fundamentally shifted.

The current environment differs sharply. Long-end yields are rising not from technical positioning but from three structural forces: expanding fiscal deficits increasing duration supply, persistent inflation uncertainty, and concerns that equilibrium real rates have shifted structurally higher. AI infrastructure spending — hyperscale data center capex, power infrastructure, and broader reindustrialization — is making capital scarcer and more expensive.

"Investors can typically tolerate weak growth, high inflation, or fiscal deterioration — but not all three simultaneously," Meschoulam said. Treasury buybacks and issuance restructuring are insensitive to these forces. They can influence the quantity of duration the market must absorb but cannot materially change inflation expectations, the fiscal trajectory, or the equilibrium real rate.

The most accurate reading of Bessent's move, Goldman concludes, is that it manages the market's perception of duration risk rather than eliminating the risk itself. The 10-year yield's return to 4.684 percent within 24 hours of the announcement suggests the market shares that assessment. Robin Brooks, senior fellow at the Brookings Institution, was more blunt: "This is less about solving the underlying problem — reducing debt and maintaining more modest budget deficits — and more about trying to manipulate the yield curve."
