Interest rates increased on Thursday, raising concerns among investors about the large government debt, significant borrowing by tech companies, and the Federal Reserve’s stance on inflation. The yield on the 10-year Treasury note, a critical benchmark for mortgage rates, climbed back to 4.69%. This followed attempts by Treasury Secretary Scott Bessent to control longer-term borrowing costs by announcing an expansion of the bond buyback program from $2 billion to $4 billion per operation starting next month. The aim is to boost the prices of 10-year to 30-year bonds, as bond yields drop when their prices rise.
Bessent mentioned on CNBC that the bond repurchase program could exceed $4 billion, indicating flexibility in their strategy. He stated, “We believe that the yields don’t reflect the underlying fundamentals.” Higher bond yields lead to increased borrowing costs for both consumers and businesses, a scenario the Trump administration wants to avoid. Rising mortgage rates have already impacted home purchases. Despite President Donald Trump’s demands for the Federal Reserve to lower rates, financial markets mainly drive these increases. On Thursday, the 30-year bond yield rose to 5.23%, slightly down from its high earlier in the week.
In response to market jitters, Bessent indicated that the Trump administration plans to unveil a strategy to reduce the federal budget deficit soon. He attributed the current deficit spikes partly to tariff refunds, a transient issue. Although the national debt recently surpassed $40 trillion after breaching $39 trillion in April, the Congressional Budget Office projects an annual deficit exceeding $2 trillion this year, an unusual figure outside of recession periods.
According to Gennadiy Goldberg from TD Securities, resolving the deficit largely depends on Congress’s actions, not the Treasury. He remarked, “The market remains skeptical about Treasury’s ability to backstop these issues.” Another factor influencing rising yields is the substantial debt being accrued by Big Tech companies to build AI data centers. This increases the supply of bonds, pushing down prices and raising yields.
Inflation continues to be a concern as oil prices rise, influenced by the uncertainty surrounding the war with Iran, impacting tankers’ access to the Persian Gulf. Prices climbed on Thursday after President Trump threatened severe economic actions against Iran. Brent crude’s price is near $94 per barrel compared to approximately $72 before the conflict began.
The Federal Reserve typically counters inflation by increasing its benchmark interest rate to slow down economic activity. However, new Fed Chair Kevin Warsh has not indicated whether this step will be taken. In a July press conference, he caused confusion over the approach towards rate increases and hinted at potentially changing the Fed’s preferred inflation measure, currently set at 2%. With inflation exceeding this target for over five years, reaching 3.7% in June, uncertainty surrounds the Fed’s commitment to addressing it. Mark Cabana from Bank of America Securities suggests the uncertainty about tackling inflation contributes to elevated borrowing costs.
Warsh emphasized that he prefers financial markets to set interest rates based on economic conditions rather than speculative Fed actions. However, Bessent’s interventions might conflict with this objective, prompting markets to anticipate potential Treasury measures to curb rates. Warsh faces pressure to clarify his strategy next Friday in a speech at an annual Fed conference in Jackson Hole, Wyoming. The market currently questions Warsh’s stance and whether he will articulate an improved plan.
After ending Jerome Powell’s term, Trump appointed Warsh, previously criticized for not reducing rates. This has raised questions about Warsh’s willingness to cut rates to align with Trump’s preferences. Following the Fed’s late July meeting, shorter-term bond yields dipped while longer-term yields rose, which BNP Paribas strategists interpreted as an unusual reaction possibly indicating the Fed’s intent to maintain lower benchmark rates.
Despite Bessent’s talk of billion-dollar bond buybacks, the scale of the Treasury market implies limited impact from such measures. Analysts at Macquarie estimate that to finance its operations, the U.S. government will need to issue nearly $550 billion in bonds this quarter. History shows that government efforts in the bond market yield temporary relief without significantly reducing borrowing costs if fiscal conditions, inflation, or supply issues remain challenging, as noted by UBS Wealth Management strategists.
