- The recent auction of $139 billion in medium-term U.S. Treasury bonds exhibited a tail and weak terminal demand pushed the 10-year U.S. Treasury yield up by 2.8 basis points to 4.338%.
- The end-investor participation rate for the 5-year Treasury fell to 87%, below the average of 89% over the last 12 auctions, reflecting market demands for higher liquidity discounts in anticipation of the Federal Reserve's prolonged high-rate policy.
- With geopolitical stalemates and the upcoming Federal Open Market Committee (FOMC) meeting, JPMorgan Chase (JPM:US) projects that the benchmark interest rate may remain at its current level until the first half of 2027, raising the anchored pricing of long-term yields.
Weak Auction and Yield Curve Reassessment
The U.S. Treasury market is facing significant absorption pressure after a series of large-scale bond auctions. As primary market supply expands, secondary market investors habitually sell off early to build yield discounts to counter supply shocks. The 10-year Treasury yield registered an upward movement in afternoon trading, reaching a phase high of 4.338%, marking the largest weekly rise since mid-March. Simultaneously, the 30-year U.S. Treasury yield rose by 2.8 basis points to 4.944%. The overall upward movement of long-term rates reflects a cautious assessment of the U.S. Treasury's continued debt issuance capacity and the risk of sustained high levels of future inflation.
Marginal Weakening of End-Demand Indicators
This round of auctions displayed structural divergences in demand across different maturity bonds. The 2-year Treasury auction results were lukewarm, with winning rates slightly above secondary market levels at the time of the bid deadline, indicating higher premiums demanded by primary dealers and end institutions. More notably, the 5-year Treasury auction, which is highly sensitive to the Fed's mid-term policy path, showed that the end-investor participation rate, including direct and indirect bids, was only 87%, below the historical average of 89%. The drop in this key indicator suggests that allocation funds are less willing to increase positions in medium-term Treasuries at current rate levels, with market liquidity concentrating towards higher returns or shorter-duration assets.
Liquidity Test of Short-Term T-Bills and New Supply
While long-term Treasuries are under pressure, the U.S. Treasury issued a total of $166 billion in 13-week and 26-week short-term T-Bills. The large scale of short-term debt further drained marginal market liquidity. The two-year Treasury yield, reflecting short-term rate expectations, rose by 2.6 basis points to 3.802%, also marking the largest weekly increase since mid-March. The market's current focus has shifted to the upcoming $44 billion seven-year Treasury auction. Should the bid-to-cover ratio and tail data for this maturity further deteriorate, it may trigger deeper concerns about a tightening liquidity environment in the fixed income market, thereby increasing overall borrowing costs.
Policy Outlook and Geopolitical Overlay
The bond market's pricing mechanism is currently constrained by both geopolitical and macro monetary policies. Iran's proposal to postpone nuclear project negotiations, requiring the U.S. to cease hostile actions and restore Gulf shipping, adds long-term geopolitical friction and uncertainty to global energy supply chains. The scrutiny by U.S. President Donald Trump and his national security team on this plan injects tail risks into the macro market. According to Ameriprise (AMP:US), at the upcoming FOMC meeting, Jerome Powell's assessment of whether oil price rises are enduring and the policy statement's articulation on restrictive rate levels will directly influence the U.S. Treasury market's volatility benchmark for the next quarter.
Medium to Long-term Evolution of Macroeconomic Rate Path
As the Federal Reserve shifts to a more defensive policy stance, Wall Street investment banks are significantly revising their rate path models. JPMorgan Chase (JPM:US)'s latest research report extends the expectation of stable rates to the first half of 2027 and even points out the tail risk of a rate hike in the second half of 2027. The entrenchment of this long-term high-rate expectation is altering the traditional cyclical trading logic of the bond market. Investors currently prefer to maintain neutral duration before the FOMC meeting, awaiting official guidance on inflation progress and economic momentum to provide clear trend judgments and recalibrate the risk exposure of their fixed income portfolios.
