Key Takeaways

• Bessent’s Intervention Falls Flat:Treasury Secretary Scott Bessent’s announcement to double long-end buyback operations failed to assuage investor concerns, leading to a fresh wave of selling in long-dated US Treasuries and continued yield rises.
• Fiscal Reality vs. Budget Assumptions:The market’s reaction underscores a growing disconnect between ambitious government budget assumptions (e.g., Fed cuts, yield rallies, robust growth, contained inflation) and the prevailing macroeconomic and fiscal realities.
• Modest Impact on Net Supply:Despite the fanfare, the planned increase in buybacks constitutes a negligible reduction in net long-dated Treasury supply (from $103bn to $97bn this quarter), highlighting the immense challenge of managing the US’s $40tn debt pile amidst persistent deficit spending.

Unless you’ve been living under a rock, or have maybe been lost down a rabbit hole of dataviz-rendering, you’ll have seen that Treasury secretary Scott Bessent has arrived to save the US bond market. Here’s how that is going at time of pixel:

US long-term government bonds were hit with a fresh wave of selling on Thursday as Treasury secretary Scott Bessent’s intervention to prop up the market failed to soothe investor jitters.

Long-dated US Treasury yields have been rising quite a lot, further complicating the Treasury’s already complicated job of refinancing the federal government’s $40tn of debt at rates that don’t make budget maths too awkward. This trend reflects a broader recalibration in the fixed income market, driven by persistent inflation concerns, the Federal Reserve’s “higher for longer” monetary policy stance, and an unprecedented supply of new government debt.

The relentless ascent of long-term yields signals that investors are demanding a higher premium for holding US government debt over extended periods. This ‘term premium’ has been under pressure for a while, influenced by factors ranging from the winding down of quantitative easing (QE) by global central banks, which previously absorbed vast quantities of government bonds, to dwindling foreign demand for US assets amid geopolitical shifts and a stronger dollar.

As things stand, Table S–1 (Economic Assumptions) of the Trump administration’s federal budget assumes the Fed will cut and that bond yields will rally. And the bond market is not, so far, obliging:

The underlying disconnect is stark. The budget baseline projects around 3 per cent per annum economic growth and inflation at around 2.2 per cent per annum, alongside an expectation of future Fed rate cuts. However, the market currently prices in a more cautious outlook, questioning both the sustainability of such growth without inflationary pressures and the likelihood of significant rate reductions given the Fed’s resolute stance against premature easing. In this environment, higher bond yields translate directly into higher borrowing costs for the US Treasury, exacerbating an already challenging fiscal picture. This means the US is poised to record even larger budget deficits, unless some *new* Department of Government Efficiency is able to make the maths work better, which seems unlikely given the structural nature of entitlement spending and national priorities.

The implications of this are far-reaching. Higher debt servicing costs could crowd out other essential government spending, potentially hindering future economic growth and investment in critical areas. Moreover, the upward pressure on long-term rates serves as a benchmark for borrowing costs across the economy, impacting everything from mortgage rates and corporate bond yields to municipal financing, thereby tightening financial conditions for businesses and households alike.

So we can see why secretary Bessent pulled out his big guns, announcing that he would “at least double” nominal long-end liquidity support buyback operations. Such operations are typically designed to inject liquidity into specific segments of the market, smoothing out supply-demand imbalances and potentially signalling a Treasury’s commitment to managing its yield curve. However, the efficacy of such an intervention hinges on its scale and the market’s perception of the Treasury’s overall strategy.

Presumably they’ll stop minting long-dated bonds too? Hmm. The US Treasury issued its quarterly refunding statement only two weeks ago. And the statement said that they planned to continue to sell just as many long-dated US Treasuries this quarter as they sold last quarter. Which is to say they plan to print $111bn of new 20-year and 30-year bonds:

This $111bn is gross issuance. And we need to adjust it for the previously announced tentative schedule of Treasury buyback operations, which included four scheduled operations to go out and buy a maximum of $2bn of 20-30yr Treasuries — the first of which was executed on August 17.

Yesterday’s announcement of plans to “at least double” the rest of the scheduled buyback operations can be read as a change to net supply of at least $6bn over the quarter. But quite possibly more. This figure, while not insignificant in isolation, must be weighed against the sheer volume of new issuance. The market’s lack of positive response suggests that investors view this as a piecemeal solution rather than a fundamental shift in fiscal policy or supply management. The persistent “bond vigilantes” of the market are clearly signaling that the current trajectory of US fiscal policy, coupled with aggressive debt issuance, requires a more substantial intervention or a more credible long-term strategy.

In light of the news, how many long-dated US Treasuries does the administration plan on dumping on the market this quarter?

By our count, following the announcement, Treasury is set to issue a net $97bn of new 20-30yrs this quarter, down from a previous $103bn.

We’re not entirely unsympathetic to the idea that finance ministries around the world shouldn’t stop pumping out long-dated securities when the economics of doing so look bad. But as the market appears to be telling the Treasury secretary, this announcement doesn’t really move the needle. The scale of the fiscal challenge, with a national debt spiraling past $33 trillion and projected to grow, demands a more comprehensive approach than minor adjustments to buyback schedules. Investor confidence, once shaken, requires concrete, structural reforms or at least a transparent, long-term plan to address the underlying supply-demand dynamics and fiscal sustainability concerns that are currently driving yields higher.

Market Impact

The market’s tepid reaction to Secretary Bessent’s intervention signals continued pressure on US long-term Treasury yields. Investors should brace for persistent volatility in the bond market as supply continues to outstrip demand, driven by ongoing fiscal deficits and the Federal Reserve’s quantitative tightening. This environment suggests higher borrowing costs will likely persist across the economy, impacting mortgage rates, corporate debt issuance, and potentially cooling growth. The failure to reassure markets could also lead to a reassessment of the US’s fiscal health by credit rating agencies and international investors, potentially diminishing the safe-haven appeal of Treasuries over the long term. Future Treasury auction results and the ongoing debate surrounding US fiscal policy will be critical indicators of market sentiment and the trajectory of interest rates moving forward.
