WASHINGTON

Treasury Secretary Scott Bessent's $6 billion repurchase of 10- to 20-year bonds backfired Wednesday, with the 10-year yield surging to 4.85 percent—its highest level since November 2023—immediately after the announcement at 11 a.m. ET.

The operation was designed to reduce supply and pull yields lower. Instead, the market sold off. The 20-year hit 5.3 percent and the 30-year followed higher. By 4 p.m. ET, yields had retreated from intraday highs but remained well above pre-announcement levels.

Equity markets buckled under the weight. The Nasdaq Composite fell 0.6 percent and the S&P 500 dropped 0.5 percent.

Bessent had characterized recent yield moves as a "fever" driven by narrative rather than fundamentals, telling Breitbart on Tuesday that his job was to "push things back towards equilibrium." The framing suggested the secretary believed yields had decoupled from economic reality.

Yields have climbed steadily since January, accelerating sharply in late July after Federal Reserve Chair Kevin Warsh stopped short of committing to aggressive inflation-fighting measures at a news conference.

Inflationary pressures have mounted from multiple directions: geopolitical risk tied to the Iran conflict and tariff uncertainty under President Trump's trade agenda, which has raised import prices across categories.

Wall Street observers say the Treasury has exhausted its credibility in the market. Legendary investor Stanley Druckenmiller warned in a Wall Street Journal opinion piece last month that "Once markets believe Treasury is defending a price, every rise in yields becomes a test of official resolve, and the operations must grow to survive the tests." One Point BFG Wealth Chief Investment Officer Peter Boockvar underscored the dynamic Wednesday, noting that if investors believe fundamentals warrant higher yields, they will continue testing official resolve.

Many market participants argue the fundamentals do support a higher yield environment. U.S. national debt surpassed $40 trillion weeks ago—a level never before recorded—forcing the Treasury into deeper reliance on international buyers to absorb its issuance at current yields. That structural reality is difficult for any buyback operation to overcome.
