In a surprise move to counter the recent surge in long-dated Treasury yields to multi-year highs, the US Treasury announced it will significantly expand its buyback operations for longer-maturity securities. Just two weeks after unveiling its quarterly repurchase schedule, the department said Wednesday it will at least double the size of its liquidity support repurchases for bonds ranging from 10 to 30 years in maturity. Treasury Secretary Scott Bessent had activated the buyback program last year, describing it as part of a broader toolkit that could be deployed if needed to address disorderly conditions in the Treasury market.
Following the announcement, yields across all maturities declined. The 30-year yield fell 9 basis points to 5.19%, while the 10-year yield — often referred to as the global benchmark for asset pricing — dropped more than 6 basis points to 4.644%. In its statement, the Treasury said the expanded repurchase size reflects its desire to provide greater liquidity support in the long-end nominal sector, noting that market participants have shown consistent and strong subscription interest in these areas, evidenced by the high volume of quality bids frequently received in long-dated buyback operations.
John Briggs, head of US rates strategy at Natixis North America, commented on the timing: "The key here is the timing. In my view, this is no accident, so the signal it sends is even more important. If yields rise too high, the Treasury will attempt to rein them in — and now we know some of the critical stress points."
This significant Treasury announcement comes amid growing market anxiety over a global selloff in long-dated government bonds. Early Tuesday, the 30-year yield touched its highest level since 2007 at 5.32%, up about 46 basis points from late June, while the 10-year yield hit 4.74%, accumulating a 35 basis point rise since summer and approaching 18-month highs. Government bonds outside the US have also come under pressure, with several markets reaching or nearing multi-decade yield peaks. Germany's benchmark 10-year yield hit a 15-year high, France's 10-year reached its highest since 2008, and Japan's 10-year climbed to 2.941%, breaking through the 30-year peak set this spring. Yields in the UK, Italy, Switzerland, and Canada also surged sharply across various maturities.
While each bond market is influenced by domestic factors, the structural forces driving yields higher share common global roots. On one hand, there are concerns that an increasingly fragmented world order will make economies more vulnerable to supply shocks, keeping inflationary pressures persistent. On the other hand, bondholders worry that governments are struggling to control fiscal spending, forcing interest rates to remain elevated for a longer period.
Within this storm, US Treasuries have drawn the most attention. Against a backdrop of cooling expectations for Federal Reserve rate cuts, the key reason for the selloff in long-dated bonds lies in the risk premium. Holding long-term Treasuries means facing fiscal supply, inflation volatility, and policy uncertainty, so investors are demanding significantly higher compensation. Additionally, uncertainty surrounding Fed policy communication has emerged as a new factor contributing to the rising term premium, while large tech giants shifting toward bond markets for financing have also diverted some demand away from Treasuries.
Dan Coatsworth, market analyst at AJ Bell, noted Tuesday that with repeated failures in efforts to end conflicts, investors are now most worried about inflation risks and potential rate hikes. He added: "The rise in long-end yields isn't just about rate hike expectations and inflation. It also reflects concerns that governments are borrowing too much, and investors are demanding higher compensation to hold long-dated bonds."
Deutsche Bank analyst Jim Reid pointed out that the recent bond market decline was not driven by a single event, "but with no sign of an agreement between the US and Iran, investors are beginning to price in a longer period of Strait of Hormuz closure. Market expectations are for oil prices to stay elevated for an extended time. Growing concerns over a prolonged blockade are adding pressure to fixed income markets, with long-dated sovereign bonds hit particularly hard."
Meanwhile, traders are also preparing for a $16 billion new 20-year Treasury auction. On Wednesday local time, the Treasury will issue $20 billion in 20-year bonds, with approximately $16 billion representing new issuance to investors. With long-dated yields persistently elevated, this auction is becoming a key window for the market to gauge investors' appetite for US fiscal health and debt supply absorption capacity. The core question centers on how high interest rates will need to go to continue attracting global capital into US debt as government borrowing needs keep expanding. Over the past week, the Treasury market has already sent similar signals — the 10-year auction produced a high yield of 4.683%, the highest in 19 years, while the 30-year auction high yield reached 5.216%, the strongest in 25 years.
