U.S. DAO controls and spends.">Treasury Secretary Scott Bessent prepared to detail fresh sanctions against Iran on Aug. 24. The announcement kept U.S. Treasury yields news in focus after long-dated yields stayed near multi-year highs. Markets watched for spillovers across oil, equities, the dollar, and 比特币.

这一时机至关重要，因为国债市场此前已面临来自债务担忧和地缘政治风险的双重压力。几天前，贝森特还增加了长期债务回购规模，使财政部政策与更广泛的金融状况联系得更加紧密。

美债收益率动态使市场焦点聚焦于长期压力

美国国债收益率新闻与收益率曲线长端保持紧密关联。路透社报道称， 30 年期美国国债收益率 周一早盘徘徊在 5.2518% 附近。该水平接近近期创下的 19 年高点 5.3371%。

The Treasury had intervened earlier through larger liquidity-support buybacks. Reuters reported that Treasury doubled planned purchases for 10-year to 30-year securities. The department raised the maximum to at least $4 billion per operation from $2 billion.

此次调整涵盖了10年至20年期以及20年至30年期板块。财政部将更高的购买上限安排在9月9日至11月4日期间实施。路透社报道称，30年期收益率在该公告发布后有所下降，随后又收复失地。

Treasury’s Aug. 5 refunding statement provided broader context for the program. The department projected up to $38 billion of quarterly liquidity-support purchases. It also planned up to $25 billion for cash-management buybacks.

美债收益率消息遭遇伊朗制裁风险

贝森特关于伊朗的声明为债券市场增添了又一个变数。路透社报道称，他计划在周一的新闻发布会上阐述更严厉的制裁措施。伊朗此前也威胁要对支持华盛顿经济限制措施的国家进行报复。

在简报会召开之前，石油市场起初走低。路透社报道称，布伦特原油报每桶93.07美元，跌幅为1.4%。美国原油下跌1.6%至85.64美元。

此前，布伦特原油周涨幅达到6.6%。这一逆转表明交易员已经将部分地缘政治风险计入价格。然而，霍尔木兹海峡依然是能源供应担忧的核心所在。

当运输和生产成本上升时，油价上涨可能会强化通胀预期。这种动态会对长期债券造成压力并推高收益率。当前美国 国债收益率 因此对影响原油流向的任何制裁依然保持敏感。

财政担忧也令美元承压。路透社报道称，美元指数在创下上周下跌0.8%的跌幅后交投于96.832附近。投资者一直将注意力集中在不断增长的美国债务和政策的不确定性上。

财政借款对各类风险资产施加压力

Treasury borrowing plans added to that debate. Treasury Fiscal Data showed total public debt had moved above $40 trillion by Aug. 20. The milestone strengthened attention on issuance needs, debt-service costs, and demand for longer maturities.

该部门预计7月至9月期间面向公众持有的净可交易借款为7390亿美元。财政部这一估计的基础是9月底9500亿美元的现金余额。

Treasury also projected $628 billion in borrowing for October through December. Large issuance requirements can influence term premiums when investors demand higher compensation for duration risk. That pressure matters most when inflation expectations and geopolitical uncertainty rise together.

CoinMarketCap的数据显示，比特币在周一交易时段交投于77,298美元附近。该资产也受益于近期美元走弱以及风险偏好的转变。然而，较高的美债收益率可能会增加持有非收益资产的机会成本。

Crypto markets therefore faced two competing forces. Dollar weakness can support scarce assets, while elevated long-term yields can tighten financial conditions. The balance between those forces remained important for 比特币 and related equities.

CoinGlass showed continued activity across 比特币 derivatives markets. Its public page did not provide a timestamped funding figure in the reviewed data. That limited any firm conclusion about leverage positioning before Bessent’s briefing.

美债收益率新闻迎来下一个政策催化剂

美债收益率新闻的下一个催化剂仍然是贝森特于周一晚些时候宣布的制裁消息。市场还在等待美联储主席凯文·沃什（Kevin Warsh）在8月28日杰克逊霍尔会议上的讲话。

路透社表示，期货市场定价显示9月加息的概率约为40%。7月的通胀数据可能会在美联储9月16日会议之前改变这些预期。

对于债券和加密货币交易员来说，当务之急是传导机制。如果对伊朗的制裁收紧了能源供应，通胀预期可能会再次升温。如果油价保持平稳，财政担忧和美联储的指引可能会重新占据主导地位。
