#美国财政部将回购上限翻倍至40亿美元 Eastern Time on August 19, 2026, the U.S. Department of the Treasury announced that the single-transaction liquidity-provision repurchase limit for 10–30-year long-term Treasury securities will be doubled from $2.0 billion to at least $4.0 billion. The new rule takes effect on September 9 and runs through November 4.
The immediate trigger is sustained selling pressure on long-dated U.S. Treasuries—on August 18, the 30-year yield briefly hit 5.334% intraday, the highest since June 2007. Behind this are multiple forces interwoven: the U.S.–Iran conflict lifting inflation expectations, the federal budget deficit already reaching $1.8 trillion for the first 10 months of fiscal year 2026, overseas holders reducing positions, and the wave of AI investment prompting companies to issue large amounts of debt, which crowds out Treasuries. The Treasury aims to inject liquidity by “stepping in” with long bonds and to suppress long-end yields, but relative to the roughly $40 trillion total Treasury market size, $4.0 billion is merely “a drop in the bucket,” and the effect lasts less than 24 hours.
Short term 📈: Falling long-end rates are beneficial for high-valuation growth stocks. Valuation pressure on semiconductor names such as NVIDIA (NVDA), AMD, Micron Technology (MU), Marvell Technology (MRVL), and Applied Materials (AMAT) should ease temporarily.
Medium to long term 📉: Structural pressure from deficits and the debt profile remains unresolved. The 30-year yield still holds above 5.2%, and long-duration assets such as NVDA, AMD, and MU continue to face headwinds.
This “cooling shot” treats symptoms rather than the root cause. What the market is truly waiting for is clarity on the Treasury’s fiscal consolidation plan and the Fed’s potential September rate-cut path.
