The Bessent Put: Can policymakers stop bond yields rising?

Key takeaways

• Bond yields are rising because governments and businesses need more capital, increasing the supply of debt investors must absorb.
• The "Bessent Put" refers to efforts by US Treasury Secretary Scott Bessent to help keep long-term borrowing costs under control through measures such as Treasury buybacks and debt management.
• The fundamental debate is whether rising yields should be managed or allowed to reflect growing fiscal deficits and borrowing needs, with implications for inflation, the US dollar and other asset classes.

It has been a difficult few months for bond investors.

Initially, rising yields could largely be explained by events in the Middle East. Higher oil prices following the Iran conflict raised concerns about inflation and reduced expectations for interest rate cuts.

As the summer progressed, however, the focus shifted. While the conflict has dragged on longer than many expected, oil prices have stabilised at around $80 per barrel and remain below the highs reached during the initial stages of the war.

Yet, US government bond (“Treasury”) yields have continued to climb. Investors are increasingly asking a different question: who will finance the world's growing borrowing requirements?

That debate sits at the heart of the recent discussion surrounding US Treasury Secretary Scott Bessent and what some investors have started calling the "Bessent Put".

More borrowing, higher yields

At its simplest, bond markets are driven by supply and demand. Today, both governments and companies want more capital. Governments across the developed world continue to run large fiscal deficits. At the same time, companies are embarking on one of the largest investment cycles in modern history as they build the infrastructure required for AI.

The world's largest technology companies are spending hundreds of billions of dollars on data centres, semiconductors, networking equipment and power generation. While some of this investment can be funded internally, an increasing share is finding its way into debt markets. The result is that more bonds are being issued and investors are demanding higher yields to absorb that supply.

For much of the period following the Global Financial Crisis, markets were remarkably relaxed about lending to governments for ten, twenty or even thirty years. Quantitative Easing (“QE”) compressed yields and fostered confidence that central banks would act as a reliable backstop. Today, that confidence is being tested. Persistent fiscal deficits, rising debt burdens and a growing pipeline of issuance have prompted investors to reassess the price of capital.

The 'Bessent Put'

Against this backdrop, Treasury Secretary Scott Bessent has adopted an increasingly activist approach to the Treasury market. The Treasury has already been relying heavily on short-dated borrowing rather than issuing large quantities of long-dated debt.

More recently, Bessent expanded Treasury buyback operations, which involve purchasing older bonds from the market. Officially, these are liquidity-management tools designed to improve market functioning. In reality, they also alter the composition of Treasury issuance. By buying back older longer-dated bonds while relying more heavily on short-dated funding, the Treasury reduces duration supply and helps limit upward pressure on long-term yields.

Equally important has been the signalling. Bessent has repeatedly emphasised that the Treasury has a broad toolkit available should market conditions deteriorate. The message to investors appears clear: policymakers are paying close attention to borrowing costs and retain a willingness to act if yields rise too far or too quickly.

The sums involved remain relatively small compared with the size of the Treasury market. Yet investors reacted strongly because many see these measures as part of a broader effort to place a ceiling on yields. Some have even drawn comparisons with early forms of yield curve control, where policymakers seek to influence borrowing costs through intervention and signalling before resorting to outright bond purchases.

This has become known as the "Bessent Put", echoing earlier concepts such as the "Fed Put", where investors believed policymakers would step in whenever markets became sufficiently uncomfortable.

Druckenmiller criticism

Part of what makes this debate so interesting is the source of the criticism. Stanley Druckenmiller is a former mentor of Scott Bessent. Both were involved in the famous trade against Sterling that culminated in Black Wednesday, when the UK was forced out of the Exchange Rate Mechanism.

Druckenmiller's argument is not really about buybacks. It is about what rising yields are trying to tell us. Historically, governments have tended to suppress bond yields during periods of crisis: wars, recessions, financial instability or deflationary shocks. What makes today's debate unusual is that policymakers are discussing ways to contain yields while the US economy remains relatively healthy, unemployment remains low and growth is robust.

As Druckenmiller argues in his Op-Ed, artificially suppressing borrowing costs during periods of prosperity risks obscuring an important market signal. His view is that higher yields may simply reflect the reality of persistent fiscal deficits and rising debt levels. In other words, the bond market may be functioning exactly as intended.

That creates a difficult dilemma for policymakers. Fiscal restraint would almost certainly help ease pressure on bond markets, but meaningful spending cuts are rarely politically attractive and become even less likely as the US moves closer to the midterm elections. If fiscal policy remains expansionary, the temptation to manage the symptoms through the bond market rather than address the underlying cause may grow.

A different view at the Federal Reserve

This debate becomes even more interesting when viewed alongside the Federal Reserve. While Treasury Secretary Scott Bessent has taken steps that may help contain government borrowing costs, the Federal Reserve retains the only balance sheet capable of genuinely controlling long-term interest rates.

Treasury buybacks and issuance decisions can influence market conditions at the margin, but sustainably capping yields is difficult without support from the Federal Reserve.

This appears to be where the philosophical divide emerges. Bessent has shown a willingness to use Treasury tools to improve market functioning and reduce pressure on borrowing costs. Recently appointed Federal Reserve Governor Kevin Warsh, by contrast, has generally sounded more comfortable allowing markets to determine the appropriate price of capital.

That distinction echoes Druckenmiller's criticism. If higher yields reflect concerns about deficits, debt levels and future funding requirements, then rising yields may not be a market failure requiring intervention. They may simply be a market signal.

The bull case and the bear case

The optimistic interpretation is that Bessent understands markets are driven as much by confidence as by arithmetic. Having spent much of his career identifying sovereign stress points and market dislocations, he knows that investor expectations can sometimes matter as much as the size of any intervention.

History contains examples where a credible commitment from policymakers was enough to change market behaviour. Mario Draghi's famous "whatever it takes" pledge in 2012 is perhaps the clearest example.

Viewed through that lens, Bessent may be trying to convince investors that policymakers will not tolerate a disorderly rise in borrowing costs. If that credibility is established, intervention may never need to become particularly large. Markets could stabilise simply because investors believe the Treasury stands ready to act if conditions deteriorate.

The bear case is more straightforward. Deficits remain large, debt issuance continues to rise and AI investment is creating additional demand for capital. At the same time, central banks are no longer absorbing huge quantities of bonds through quantitative easing and some traditional buyers of government debt are becoming less reliable.

If investors require a higher return to absorb that supply, yields may need to rise regardless of policymakers' intentions. If those forces are driving yields higher, then buybacks may address symptoms rather than causes. Put simply, liquidity tools cannot solve a borrowing problem and, at this stage, risk becoming a band-aid on a bullet wound.

The risk is that investors interpret such interventions not as a sign of strength, but as evidence that policymakers are becoming increasingly concerned about the trajectory of deficits, debt and borrowing costs.

What does it mean for investors?

Within the US, we are relatively neutral on duration and continue to favour Treasury Inflation-Protected Securities (TIPS), where real yields remain attractive and provide a degree of protection should inflation prove more persistent than markets currently expect.

We still believe that bonds play a decisive role in portfolios. Today's starting yields are significantly more attractive than they were for much of the last decade. Bonds continue to offer meaningful income and remain an important source of diversification should growth weaken more sharply than expected.

The most likely near-term outcome may be a period of range-bound yields rather than a decisive move in either direction. On one side sit the structural forces pushing yields higher: persistent fiscal deficits, rising issuance and growing demand for capital. On the other sits an increasingly apparent reluctance from policymakers to allow long-term borrowing costs to rise too far, too quickly.

If investors are correct that the Treasury is uncomfortable with 10-year yields materially above current levels, each move higher is likely to be met with renewed efforts to improve market functioning and ease borrowing conditions. That may not solve the underlying problem, but it could create a period of managed tension between fiscal reality and policy intervention.

The key question is where adjustment occurs from here. If policymakers succeed in limiting further increases in Treasury yields, the pressure created by growing borrowing requirements does not simply disappear. It may instead emerge through a weaker dollar, firmer inflation expectations, or stronger performance from traditional debasement hedges, such as gold.

Ironically, attempts to reassure investors may have heightened focus on the very issue policymakers are trying to address. The volume of announcements, interviews and discussion surrounding Treasury market interventions has drawn greater attention to US borrowing needs, reinforcing concerns about how those deficits will ultimately be financed.

The debate surrounding the Bessent Put is therefore about more than bonds alone. The real question is where markets choose to impose discipline: through higher yields, a weaker dollar, rising inflation expectations, or some combination of the three.
