$119 billion in U.S. Treasury long-end auctions face the “holiday exam,” as Warsh’s “de-forward guidance” playbook shows how it will reprice the yield curve?

This week, the U.S. Treasury market will face a key stress test following the Independence Day holiday.

The U.S. Department of the Treasury will complete a $119 billion plan for Treasury issuance this week. On Tuesday, it will kick off with a 3-year note auction; on Wednesday and Thursday, it will follow with benchmark 10-year and 30-year long-term bonds, respectively. What the market is generally watching is whether, upon the return from the holiday, investor demand can absorb the supply from the long end. Tom di Galoma, Managing Director at Mischler Financial Group, warned that, “Whenever large supply weeks are followed by holidays, the probability of multiple auctions seeing ‘tails’ is quite high.” Meanwhile, the Fed’s June meeting minutes, expected to be released in the middle of this week, are likely to be another focus for the bond market, as investors will assess how deep the policy divergence is within the committee under the leadership of newly appointed Chair Kevin Warsh.

Against the macro backdrop, long-end U.S. Treasuries have continued to come under pressure in recent times. Rising energy prices triggered by the Iran conflict have intensified inflation worries, and fiscal pressure has kept building up, together weighing on long-end performance. However, on Monday, Brent crude fell by about 0.6% to $71.70 per barrel, easing concerns about energy-driven inflation and providing short-term support for Treasury prices, with the 10-year U.S. Treasury yield falling by about 2 basis points to 4.46%.

Holiday effects layered on top of long-end supply; auction demand shows signs of concern

This week’s Treasury auctions total $119 billion, with long-end maturities being the core focus of market consideration. According to Bloomberg, since the outbreak of the Iran conflict, long-dated Treasuries have continued to be sold off, driven by rising inflation expectations fueled by higher energy prices, as well as the ever-accumulating fiscal pressure.

Tom di Galoma struck a cautious tone on demand prospects. He pointed out that holidays often cause market participants to be absent, and when large supply weeks coincide with holiday effects, the risk of multiple auctions simultaneously experiencing “tails”—meaning the actual auction yield is higher than the pre-sale (when-issued) yield—cannot be ignored. If this situation materializes, it would directly push up long-end yields and put pressure on investors with heavier positions.

At the same time, the ISM services data released on Monday is also worth paying attention to. Ahead of this, the June employment report came in far below expectations, prompting Treasury traders to scale back their expectations for the size of this year’s rate hikes. If the ISM data continues to weaken, it could provide some support for this week’s auctions.

Warsh’s “Less Forward Guidance” Approach; the market reads the June meeting minutes

The Fed’s June meeting minutes, set to be released in the middle of this week, will provide the market with an important window to interpret Warsh’s new leadership style.

Molly Brooks, a U.S. rates strategist at TD Securities, said that the key points of this set of minutes are not only the degree of disagreement among members, but also the document’s length and the structure of its wording. “Given Chair Warsh’s intention to reduce forward guidance, the composition and length of the minutes themselves will also be used by the market to judge whether this shift has already occurred.”

Weaker forward guidance means the market’s visibility into the future policy path will systematically decline. Investors will have to rely more on high-frequency data rather than central bank signals to calibrate interest-rate expectations. This change has far-reaching implications for the yield curve’s pricing logic—if the market cannot anchor the policy endpoint, long-end term premiums are likely to widen, and the pressure for the curve to steepen may persist.
