Bond yields rise after Treasury Department announces size of buyback operation

Bond yields rose Wednesday after the Treasury Department said it would buy back up to $6 billion of government bonds, putting a dollar figure on the operation first announced last month.

The 10-year US Treasury yield rose to 4.85%, its highest level since 2023. If the 10-year yield ends the day above 4.82%, it would be the highest closing level since October 2023.

The Treasury Department on August 19 announced it would at least double the size of bond buybacks from September to November. The announcement on Wednesday pins the buybacks at up to $6 billion, triple the size of the standard $2 billion operation.

Those buybacks are set to take place on Thursday, putting the bond market back in the spotlight. Bond yields have surged this year, raising the cost of borrowing and exacerbating concerns about affordability.

The buyback operation aims to tame rising bond yields, which have climbed in recent weeks to multi-year highs. Treasury Secretary Scott Bessent is flexing the tools at his disposal at the Treasury Department to try and temper the rise in yields.

Yields have climbed across the globe as investors reckon with surging energy prices and potential central bank rate hikes. A deluge of corporate debt to fund the AI buildout is also pushing up yields.

In the backdrop, rising government deficits and concerns over fiscal health are adding to the bond market uncertainty.

Buybacks from the Treasury Department are a standard operation in bond markets, but the size and timing of the announcement highlights the Trump administration’s sensitivity to the rise in yields.

While the buybacks can provide short-term relief, they don’t change the fundamentals contributing to higher yields, from rising corporate debt issuance to lingering concerns about government deficits.

Yields rise when bond prices fall. Investors are selling bonds, pushing prices lower and yields higher. The rise in yields is lifting borrowing costs for consumers and governments alike.

Bond yields help set interest rates across the economy. The 10-year US Treasury yield is the benchmark for mortgage rates. As the 10-year yield has surged this year, mortgage rates have climbed. The average 30-year fixed mortgage rate rose last week to its highest level since July 2025.

A surge in bond yields can make life less affordable and compound concerns about the cost of living.

The rise in yields is a global phenomenon, with borrowing costs in Europe and Asia also hitting multi-year and multi-decade highs. Bond yields in France, Italy and the United Kingdom also surged on Wednesday.

周三，美国财政部宣布将回购至多 60 亿美元的政府债券，这一消息公布​​了上个月首次宣布的回购操作的具体金额，受此消息提振，债券收益率应声上涨。

10年期美国国债收益率升至4.85%，为2023年以来的最高水平。如果10年期国债收益率当日收盘价高于4.82%，这将是自2023年10月以来的最高收盘价。

美国财政部8月19日宣布，将9月至11月的债券回购规模至少翻一番。周三公布的公告显示，回购规模将高达60亿美元，是通常20亿美元回购规模的三倍。

这些债券回购计划定于周四进行，将债券市场再次推向风口浪尖。今年以来，债券收益率飙升，推高了借贷成本，加剧了人们对债务负担能力的担忧。

此次债券回购计划旨在抑制不断攀升的债券收益率，近几周来，债券收益率已攀升至多年来的高位。财政部长斯科特·贝森特正在动用财政部掌握的所有工具，试图平息收益率的上涨。

由于投资者担忧能源价格飙升和央行可能加息，全球收益率普遍攀升。此外，为人工智能建设提供资金的大量企业债务也推高了收益率。

随着中东冲突升级，全球债券遭到抛售，进一步加剧了人们对通胀的担忧。

在此背景下，不断上升的政府赤字和对财政状况的担忧加剧了债券市场的不确定性。

财政部回购债券是债券市场的常规操作，但此次公告的规模和时机凸显了特朗普政府对收益率上升的敏感度。

虽然股票回购可以提供短期缓解，但它们并不能改变导致收益率上升的基本面，例如企业债务发行增加以及对政府赤字的持续担忧。

债券价格下跌时，收益率上升。投资者抛售债券，导致价格走低，收益率上升。收益率上升推高了消费者和政府的借贷成本。

债券收益率有助于设定整个经济体的利率。10年期美国国债收益率是抵押贷款利率的基准。随着今年10年期国债收益率飙升，抵押贷款利率也随之攀升。上周，30年期固定抵押贷款的平均利率升至2025年7月以来的最高水平。

债券收益率飙升会降低生活成本，加剧人们对生活成本的担忧。

收益率上升是一个全球性现象，欧洲和亚洲的借贷成本也达到了多年甚至几十年来的最高水平。周三，法国、意大利和英国的债券收益率也大幅上涨。
