The U.S. Treasury market is signaling that current interest rate levels are insufficient to curb potential economic overheating. As traders increase bets that the Federal Reserve could raise rates again by at least 25 basis points as soon as October this year, the yield on the 2-year U.S. Treasury note has surged to a high not seen in over a year, around 4.15%, significantly above the Fed's policy target range of 3.5% to 3.75%. This divergence, which began in March, reflects a market repricing of policy-sensitive assets. Last week's stronger-than-expected non-farm payrolls data intensified market expectations for rate hikes and reinforced concerns about inflationary pressures and the risk of an AI-driven economic boom overheating. This week's upcoming release of May CPI and PPI figures is anticipated to further corroborate this trend.
Climbing Treasury Yields Exert Tightening Pressure on Fed
Jack McIntyre, a portfolio manager at Brandywine Global Investment Management, noted, "Interest rates are restrictive to some degree, but until a new economic variable emerges, U.S. Treasury yields could remain elevated." The yield on the policy-sensitive 2-year Treasury is trading around 4.15%, well above the upper bound of the Fed's target range. The 30-year Treasury yield has reached 5.19%, approaching its 2023 highs. The rise in U.S. Treasury yields has spread across the entire yield curve, creating policy pressure for the Fed's new Chair, Kevin Warsh. Warsh is set to chair his first monetary policy meeting and press conference next week. Warsh has previously advocated for looser policy, arguing the current stance is overly restrictive. However, the bond market is growing increasingly concerned that the Fed may be falling behind in addressing inflation and overheating risks.
Andrzej Skiba, head of U.S. fixed income at RBC Global Asset Management's BlueBay, pointed out that AI spending is fueling economic activity, leading him to worry for the first time about potential signs of the U.S. economy overheating. Two inflationary storms are gathering strength: the energy shock from the Middle East and the AI spending boom. First, the Middle East shock. The average price for Brent crude in May rose further to $103.7 per barrel, while the U.S. retail gasoline spot average has climbed to $4.61 per gallon. The pass-through effects of surging oil prices have spread more broadly—data from the Institute for Supply Management (ISM) shows the input price index hovering near its highest level since April 2022, with 16 industries, including paper, machinery, and primary metals, reporting rising raw material costs. Secondly, AI spending is also becoming an inflation concern. Skiba stated, "For the first time in a while, we are starting to consider the scenario where the U.S. economy genuinely begins to overheat." Accelerated capital expenditure is boosting demand for capital, thereby pushing up the neutral rate and making the economy more inflation-prone than it appears on the surface.
Meanwhile, former President Trump publicly pressured the Fed via media on June 7th, calling for the benchmark rate to be "slashed dramatically to 1% or lower," claiming "we built this country on low interest rates." The bond market has issued its sharpest protest yet against Warsh's dovish leanings through persistently rising yields.
Divergence in Short-Term Yields Highlights Focus on "Neutral Rate"
The yield on the 2-year Treasury has consistently traded above the upper bound of the Fed's policy rate since March, with a current premium of about 40 to 50 basis points. This is the market voting with its actions: policy is no longer restrictive and may even be too accommodative. The divergence between short-term U.S. Treasury yields and the policy rate serves as another reminder that Fed policy often lags market movements. A similar pattern of the market leading was seen during the late 2021 to early 2022 rate hike cycle. Currently, investors and analysts are refocusing on the Fed's long-term measure of the "neutral rate"—the theoretical borrowing cost that neither stimulates nor restrains economic growth. The FOMC's March projection for the long-run neutral rate was around 3.1%. Analysis suggests the ongoing AI capital expenditure boom is pushing the neutral rate higher by increasing capital demand. Market pricing currently implies a real, inflation-adjusted neutral rate of about 1.8%, significantly above the Fed's estimated median of 1.1%. This is a potential "landmine" that Warsh must navigate carefully in his first press conference. If he believes the neutral rate is higher than the Committee's estimate, then holding rates steady means policy is effectively no longer restrictive, making a rate hike potentially necessary. If he leans towards maintaining the Committee's current lower estimate, he must confront the risks of persistently rising bond yields and climbing inflation expectations.
Anshul Pradhan, head of the rates strategy team at Barclays, pointed out that the debate over accelerating labor market demand and monetary policy restrictiveness could push assumptions for the neutral rate higher, affecting the entire yield curve, not just the short end. Kevin Flanagan, head of investment strategy at WisdomTree, believes the appropriate level of the neutral rate is crucial for Warsh's policy formulation, noting his predecessor Powell had previously hesitated over whether a 3.5% neutral rate was appropriate.
Have Treasuries Already Done the Fed's Job? High Yields Impact Mortgages and Corporate Borrowing
Currently, the 10-year U.S. Treasury yield sits around 4.5%, directly raising the cost of mortgages and corporate borrowing. Research estimates that the recent rise in Treasury yields is equivalent to the Fed having raised rates by about 75 basis points. Analysts note that this yield increase could support the Fed in holding rates steady in the near term, but if inflation data continues to run above target, the Fed will have to consider further hikes. Investors will also closely watch upcoming Consumer Price Index (CPI) data and the potential impact of international events, such as oil price increases stemming from conflict involving Iran, on inflation. Flanagan concluded, "If the CPI does not show a clear uptick in inflation, the bond market sell-off could be limited, or we might even see a modest rally. But fundamentally, a 4% yield level has become the new normal for the entire yield curve."
