President Donald Trump has floated the possibility of deploying the military as an "intervention" tool in the bond market, a statement that has added a new layer of uncertainty to ongoing efforts to stabilize Treasury yields. The remark came in response to questions about Treasury Secretary Bessent's recent actions to address surging long-term yields, though Trump's answer left many observers puzzled.

The Treasury Department surprised Wall Street on Wednesday by announcing that it would "at least double" its buyback program for long-term US Treasuries starting next month. This move initially triggered a significant rally in long-dated bond prices, pulling the 30-year yield down noticeably from its highest level in 19 years, which was hit just days earlier. However, the decline proved short-lived as yields have since crept back upward.

On Friday afternoon, while speaking to reporters on the tarmac before boarding Air Force One, Trump was asked whether he had directed Bessent to intervene in the bond market and if the action originated from his own idea. Trump responded: "No, not at all. He's a very capable person, he did it on his own. He's very good at it. He has a great feel for bonds and interest rates, a very good natural instinct." When asked whether he had discussed other forms of intervention with Bessent and whether further measures might follow, Trump added: "We have many ways to intervene, this is just one of them." He then stated: "The ultimate intervention would be our military. If we have to use the military, we will."

Bessent had mentioned in an interview on Thursday that the administration possesses a "large policy toolbox" for stabilizing the bond market, but he declined to specify what other tools might be available. Following Trump's latest comments, it has become increasingly difficult to determine whether the two are even referring to the same set of options.

The recent climb in Treasury yields has been driven by market concerns over fiscal deficits, ballooning government debt, persistently elevated inflation, and a wave of debt issuance by technology companies financing massive investments in artificial intelligence. The current focus of market discussions centers on what tools Bessent might deploy if yields rise again, and whether the Federal Reserve could eventually be forced to step in should the Treasury's "firepower" prove limited.

Analysts have pointed out that the fundamental issue with Treasury intervention is that it requires funding. Currently, the Treasury is financing these operations mainly by reducing long-term debt issuance and increasing short-term debt. However, since total federal debt is constrained by the debt ceiling, the Treasury will eventually run out of ammunition. If that happens and yields spike once more, the Fed may feel compelled to purchase these bonds. Should such a scenario unfold, any internal discussions by Fed Chair Kevin Warsh about shrinking the central bank's balance sheet would lose practical relevance. Instead of exiting the fiscal arena, the Fed could find itself drawn further into it.

One potential next step for the Treasury involves adjusting the issuance structure of long-term bonds. The Treasury's latest quarterly debt issuance policy statement included revised language that has fueled widespread speculation that officials may consider reducing auction sizes for the longest-dated securities while concentrating any future issuance increases in lower-cost short and medium-term maturities.

Gregoire Pesque, global head of fixed income at French asset manager Amundi, stated that while Treasury buybacks can send signals to the market, buybacks alone are insufficient to reverse the overall direction of yields. He also suggested that the Fed may still need to raise interest rates to solidify its credibility in fighting inflation. Strategists at Goldman Sachs have echoed similar views, arguing that no matter how many measures the Treasury implements, the most effective way to push down yields is to bring inflation down.

This issue is expected to be a central topic when Fed Chair Kevin Warsh delivers his keynote speech at the Kansas City Fed's Jackson Hole Economic Policy Symposium next week. Currently, interest rate swap markets indicate that traders assign approximately a 40% probability to a Fed rate hike at the September meeting, while a full rate increase is not priced in until around the end of the year.
