US Treasury Raises Maximum Buyback to US$6 Billion

The US government has increased the scale of its Treasury bond buyback operations to a maximum of US$6 billion—three times the size of standard operations, which typically hover around US$2 billion. This move aims to boost liquidity in the long-term bond market following a surge in yields over recent weeks.

The buyback operation is scheduled for Thursday (Sept. 10), targeting Treasury securities with maturities of approximately 10 to 20 years. The US government also indicated that the subsequent operation would involve at least US$4 billion, signaling a more significant liquidity intervention than in previous periods.

However, the market response ran counter to the intended outcome. The 10-year Treasury yield spiked to around 4.85%, its highest level since November 2023. Markets had previously anticipated buybacks in the range of US$8 billion to US$10 billion; consequently, the US$6 billion announcement was viewed as insufficiently aggressive to stem the selling pressure on bonds.

Pressure on US bonds stems from a confluence of factors. Government debt has surpassed US$40 trillion and Treasury issuance continues to rise, while a surge in oil prices—climbing above US$100 per barrel—has reignited inflation concerns. Additionally, the risk of Federal Reserve interest rate hikes is prompting investors to demand higher yields for holding long-term bonds.

Treasury buybacks differ from the Federal Reserve's quantitative easing (QE) programs. This program primarily aims to purchase older, relatively illiquid debt securities and improve market trading functionality, rather than directly printing money or loosening monetary policy. As a result, the impact on yields may be limited if fundamental pressures—such as inflation, debt levels, and heavy bond issuance—remain dominant.

Market attention is now focused on the execution of the US$6 billion buyback and upcoming US inflation data. If the operation successfully boosts bond demand, yields could see a correction. However, persistently high inflation and elevated oil prices could sustain selling pressure, potentially pushing the 10-year yield back toward the psychological 5% level.

Newsmaker Analysis: The US$6 billion buyback is a significant move—being three times the usual size—yet the rise in yields following the announcement indicates that the market remains focused on US fiscal risks and inflation. For gold, a decline in yields post-buyback would serve as a positive driver by reducing the opportunity cost of holding bullion; conversely, if yields remain near 5%, the gold rally could be stifled once more. The dollar could also find support if elevated yields continue to drive demand for US assets.
