Bond Market Warnings: Goldman Sachs Says Treasury Buybacks May Not Tame Rising Yields

Bond Market Warnings are intensifying as U.S. Treasury yields climb to multi-year highs despite efforts by the government to support the long-end of the bond market. Goldman Sachs economists and rates strategists have warned that the Treasury’s expanded bond buyback program is unlikely to materially reduce long-term borrowing costs because it does not address the underlying forces pushing yields higher.

The Treasury announced on September 9 that it would buy back up to $6 billion of longer-dated government debt, tripling the size of the previous operation. The announcement initially disappointed investors, with the 10-year Treasury yield rising to around 4.85%.

Goldman Sachs Warns Buybacks May Have Limited Impact

Goldman Sachs Research said that government efforts to refinance longer-maturity debt with shorter-dated issuance are unlikely to meaningfully reduce interest rates.

George Cole, a Goldman Sachs economist, and William Marshall, the firm’s head of U.S. rates strategy, argued that changing the maturity profile of government borrowing does not fundamentally reduce the government’s overall borrowing requirements.

Goldman said the strategy can alter the average maturity of debt issuance, but that alone is not sufficient to materially change the overall level of long-term yields.

The bank’s assessment comes at a time when investors are demanding greater compensation for holding long-dated government debt.

Treasury Expands Buyback to $6 Billion

The Treasury Department’s latest operation represents a significant increase from its previous buyback size.

Treasury Secretary Scott Bessent had previously said the department would at least double its buybacks to $4 billion. The latest announcement increased the planned operation to as much as $6 billion for longer-term Treasury securities.

The buybacks are designed in part to improve liquidity and manage the maturity structure of outstanding government debt. By purchasing older Treasury securities, the government can reduce the amount of certain securities available in the market.

However, Goldman Sachs argues that this does not eliminate the underlying supply of government debt or the broader fiscal pressures affecting investors’ expectations.

10-Year Treasury Yield Nears 3-Year High

The market reaction highlighted the difficulty facing policymakers.

The 10-year Treasury yield climbed to approximately 4.85%, reaching its highest level since November 2023. Longer-dated yields were also elevated, with 20-year and 30-year Treasury yields around 5.3%.

Goldman’s research noted that the 30-year U.S. government bond yield was around 5.2% as of September 8, close to its highest level in more than two decades.

Higher yields mean higher borrowing costs for the U.S. government and can also influence mortgages, corporate borrowing, consumer loans and financial-market valuations.

Fiscal Deficits Remain a Major Concern

Goldman Sachs believes the current rise in long-term yields is not simply the result of temporary market disruption.

The bank pointed to persistent fiscal concerns as one of the key reasons longer-term yields are likely to remain elevated. Large government borrowing requirements increase the amount of debt that investors must absorb, potentially requiring higher yields to attract sufficient demand.

Goldman also highlighted strong economic performance and the increasing amount of borrowing associated with artificial-intelligence investment as factors influencing the bond market.

This means that simply changing which Treasury maturities are issued may not be enough to reverse the broader trend.

Inflation Adds Another Layer of Pressure

Inflation is another major concern for bond investors.

Energy prices have surged amid the ongoing Middle East conflict, adding to concerns that inflation could remain higher for longer. Rising energy costs can make it more difficult for the Federal Reserve to reduce interest rates quickly.

Reuters reported that U.S. bond yields have been rising alongside oil prices and broader concerns about inflation and government borrowing.

When investors expect inflation to remain elevated, they generally demand higher yields from long-term bonds because inflation can reduce the real value of future fixed payments.

Why Treasury Buybacks Do Not Solve the Core Problem

Treasury buybacks can influence the supply and liquidity of particular securities, but they do not fundamentally reduce the amount of money the U.S. government needs to borrow.

That distinction is central to Goldman’s argument.

The Treasury can change the maturity profile of its debt, purchasing longer-dated bonds and financing those purchases through shorter-term issuance. But the government’s overall financing requirement remains.

Goldman said similar attempts by governments in the United Kingdom and Japan to adjust the maturity composition of their borrowing have provided little evidence that such moves can meaningfully change the broader level of bond yields.

Investors Expected a Larger Intervention

Another reason for the negative market reaction was expectations.

Although $6 billion is three times the previous maximum operation, some investors had expected a larger buyback. Reports indicated that market participants had anticipated figures in the $7 billion to $10 billion range.

As a result, the announcement failed to provide the kind of surprise that might have generated a stronger rally in Treasury prices.

Instead, yields moved higher as investors reassessed how much influence the Treasury’s intervention could realistically have.

Rising Yields Could Affect Stock Markets

The bond-market developments extend beyond government securities.

Higher Treasury yields can make bonds more attractive relative to stocks, while also increasing the discount rate used by investors to value future corporate earnings.

That can place particular pressure on growth-oriented companies whose valuations depend heavily on expected future profits.

The rise in yields has therefore become an important issue for both bond and equity investors. The Financial Times noted that yields approaching the 5% level could create broader pressure on equity valuations and financing conditions.

Goldman Expects Long-Term Yields to Stay Elevated

Goldman Sachs does not expect all upward pressure on yields to remain indefinitely.

The bank said energy-driven inflation concerns could decline over the next six months, while greater clarity about the returns from AI-related investment could reduce some of the borrowing pressure.

However, Goldman expects fiscal concerns to persist, keeping longer-maturity yields relatively high compared with shorter-term rates.

That suggests the current bond-market challenge may be structural rather than simply a temporary reaction to one economic report or policy announcement.

What Comes Next for the Treasury Market?

The Treasury’s larger buyback operation will now be closely watched by investors.

A successful operation could improve liquidity and temporarily support prices in targeted securities. But the bigger question is whether the intervention can meaningfully change investor expectations about long-term U.S. borrowing costs.

For Goldman Sachs, the answer is likely no unless the underlying fiscal and supply-demand dynamics change.

With the 10-year yield near 4.85% and the 30-year yield above 5%, the bond market remains under significant pressure.

The coming months will therefore depend heavily on inflation, Federal Reserve policy, government borrowing needs, economic growth and investor demand for long-term Treasuries.

FAQs

What is causing U.S. Treasury yields to rise?

Several factors are contributing, including fiscal concerns, government borrowing needs, inflation expectations, strong economic activity and increased demand for capital from AI-related investment.

What is the Treasury buyback program?

The Treasury buyback program involves the government purchasing previously issued Treasury securities. The purchases can improve liquidity and alter the maturity structure of outstanding government debt.

How much will the Treasury buy back?

The Treasury announced a buyback of up to $6 billion in longer-dated government bonds, substantially larger than its previous operation.

Why does Goldman Sachs think buybacks will not be enough?

Goldman argues that buybacks change the maturity composition of government debt but do not reduce the government’s overall borrowing requirements.

What happened to the 10-year Treasury yield?

The 10-year yield rose to around 4.85%, reaching its highest level since November 2023 before easing somewhat.

Why is the 30-year Treasury yield important?

The 30-year Treasury yield reflects long-term borrowing costs for the U.S. government and can influence mortgage rates, corporate financing and investment valuations. It has recently moved above 5%.

Can Treasury buybacks lower bond yields?

Buybacks can support Treasury prices and improve liquidity, which can put downward pressure on yields for the securities being purchased. However, Goldman Sachs argues they are unlikely to materially reduce the broader level of long-term yields without changes to underlying fiscal and supply-demand conditions.

How does inflation affect Treasury yields?

Higher inflation can push investors to demand higher yields because inflation reduces the purchasing power of future fixed bond payments.

Could rising Treasury yields hurt stocks?

Yes. Higher bond yields can make fixed-income investments more attractive and increase the discount rate applied to future corporate earnings, potentially putting pressure on equity valuations.

What does Goldman Sachs expect for long-term bond yields?

Goldman expects fiscal concerns to remain a persistent source of pressure, meaning longer-term bond yields could stay elevated even if some temporary inflation pressures ease.
