A recent research report from China Securities Co., Ltd. highlights that fiscal buybacks are a standard tool used by the US Treasury to manage liquidity in older bond issues and its cash balance. While the buyback mechanism itself is not new and should theoretically have little market impact, this particular operation features two notable details: it was announced just two weeks before the quarterly buyback schedule, and liquidity in the older US bond issues remains normal. This suggests the buyback is specifically aimed at addressing Treasury yield volatility.
The report concludes that this is not a routine fiscal operation but rather a targeted effort to manage interest rate expectations, with the true objective of stabilizing US equities. For US Treasuries, the underlying macro narrative of rising yield trends remains intact, and the expanded buybacks are merely a temporary fix. For equities, this move helps ease short-term panic by stabilizing expectations. For gold, the continued integration of US fiscal and monetary policy with technology, alongside repeated erosion of dollar credibility, supports the case for de-sovereign assets like gold.
The key developments began on August 19 when the US Treasury announced an increase in the per-operation cap for liquidity support buybacks in the 10-to-20-year and 20-to-30-year maturity buckets, from $2 billion to at least $4 billion, effective September 9 through November 4. This doubles the buyback capacity for these segments, adding roughly $14 billion in purchases for the 10-to-30-year bucket this quarter.
Following the announcement, the 30-year Treasury yield fell from 5.27% to around 5.19% intraday, while the 10-year yield dipped from 4.68% to 4.65%. The US dollar index dropped about 0.7% to its lowest level since mid-May. Gold surged over 3% to its highest point since June 4, and US stocks rebounded with most S&P 500 components gaining, though chip stocks continued to decline. This came a day after the 30-year yield hit 5.33%, a level not seen since 2007, and following auctions last week where the 10-year and 30-year yields reached multi-decade highs.
Understanding Fiscal Buybacks: Is This Quantitative Easing?
Fiscal buybacks involve the Treasury using its own funds to repurchase bonds, raising the question of where these funds originate. The Treasury can either issue new debt to finance the purchases (refinancing old debt with new) or use existing cash from its General Account (TGA). The first method releases liquidity if paid directly from the TGA, while the second method involves issuing new bonds to buy back existing ones, which affects the liquidity and maturity profile of the debt. For instance, issuing short-term bonds to replace long-term ones.
In this case, the buyback targets 10-to-30-year old bonds, removing duration from the market. The funds are initially paid from the TGA and replenished through debt issuance within the quarter. At the August refinancing meeting, the Treasury confirmed that long-term bond auction sizes would remain unchanged for the coming quarters. This suggests the buyback will likely involve issuing short-term debt to fund purchases of longer-dated bonds, without involving the Federal Reserve's base money supply, meaning it is not quantitative easing.
Market Impact: What Can the Buyback Achieve?
The buyback mechanism itself is not new, having been restarted by the US Treasury in May 2024 with two categories: liquidity support and cash management. Liquidity support purchases older off-the-run bonds at fixed caps to provide a predictable exit channel for illiquid issues. However, this time there are two key differences.
First, the announcement came just two weeks after the quarterly buyback schedule was published in early August, which had set the total liquidity support cap at $38 billion, including $14 billion for the 10-to-30-year segment from September 9 to November 4. Revising the schedule mid-quarter is rare since the program's restart. Second, the US bond market is not facing significant liquidity stress. Over the past 60 trading days, the 30-year yield moved more than one standard deviation (about 4 basis points) on a third of days, consistent with the past year's norm. On August 18, a routine $2 billion buyback saw about 10 times oversubscription, indicating normal market functioning.
In 2023, when the Treasury announced the buyback program, it explicitly stated it would not engage in tactical or temporary operations, would not use buybacks to alter the debt maturity structure, and would not respond to acute market stress. This expansion breaches all three boundaries, signaling a clear intent to manage yield volatility. The conclusion is that this is not a genuine fiscal operation but a tool for managing interest rate expectations.
From Debt Management to Rate Management: The Uncontainable US Debt Problem
The expanded buyback is part of a broader strategy by Treasury Secretary Bessent to suppress yields. This includes the late-July joint US-Japan intervention to support the yen, the first since 1998, aimed at preventing Japan from selling US Treasuries; the early-August quarterly refinancing statement that subtly adjusted forward guidance to allow for reduced long-term issuance; and Bessent's frequent public defenses of communications strategy. The goal is clear: to keep borrowing costs down at least until the midterm elections, reflecting the uncontainable scale of US debt.
The root cause is record-high long-end yields. Two primary factors drive this: supply concerns, including a near-$2 trillion annual deficit, corporate debt issuance to fund the AI investment boom, and reduced traditional demand for long-duration bonds; and geopolitical and oil price risks, with the US-Iran memorandum expiring and stalled negotiations. The marginal trigger is the July fiscal deficit data, which raised concerns about rising interest costs, making debt worries the primary driver of the yield surge. Recent weak inflation, employment, and housing data have not changed rate hike expectations, indicating the move is driven by term premium rather than policy rate expectations.
Looking ahead, the two factors pushing long yields higher—government debt and AI-related issuance—are unlikely to ease. Interest payments as a share of GDP are projected to rise from 3.0% in 2024 to 3.2% in 2025. Under a neutral scenario (10-year yield at 4%, deficit at 7%), this could reach 3.5% by 2026 and 3.7% by 2028; under a pessimistic scenario (10-year yield at 5%, deficit at 7%), it could hit 4.0% by 2026 and 4.4% by 2028. With the current 10-year yield at 4.65%, we are between these scenarios. Neither US political party shows willingness to pursue fiscal consolidation, and market concerns over debt are growing. The sensitivity of rates to debt levels varies by macro conditions, with Japan, the UK, and the US showing higher sensitivity due to high debt ratios, high r-g, and weak fiscal discipline, respectively. Rising global long-term yields point to increasing elasticity.
The second factor is AI-driven debt issuance crowding out other borrowers. Investors face two major borrowers—government and AI firms—at the same duration, raising the term premium. For Treasuries, the signal value of the expanded buyback outweighs its actual impact and cannot reverse the upward trend in term premium. Bessent's measures resemble a form of soft financial repression, which is negative for the dollar and positive for gold.
Risks and Considerations
Several risks could alter the outlook. Geopolitical and oil developments: if the Iran conflict de-escalates and oil prices fall, lower inflation expectations could bring down long-term yields. Treasury tool upgrades: if the November 4 quarterly refinancing further reduces long-term issuance, or if the Fed adjusts its balance sheet runoff and reinvestment structure to support the Treasury, long-term yields could decline more than expected. AI issuance pace: a slowdown in AI capital spending and reduced corporate bond supply could ease term premium pressure. Model assumptions: the interest burden projections assume 30% annual debt refinancing, an average interest cost on outstanding debt, and a parallel shift in the yield curve, so actual outcomes may vary.
