【美财政部加码回购稳债市，美国房贷利率连降两周】在美国财政部宣布将增加长期国债回购规模、以帮助稳定债券市场后，美国抵押贷款利率连续第二周下降。房地美在一份声明中表示，30年期固定利率抵押贷款的平均利率从一周前的6.67%降至6.65%。一年前，该利率为6.58%。对于潜在购房者而言，借贷成本仍然是一大担忧，因为持续已久的伊朗战争令通胀风险居高不下。房地产网站Realtor.com高级经济学家杰克·克里梅尔写道：“收益率曲线长端的走势凸显了市场对通胀和财政前景的担忧，这可能在未来几周对抵押贷款利率形成上行压力。”

OpenAI said it will tighten safety processes for paying customers and has begun testing "private safety processing", a system designed to detect risk patterns across multiple interactions rather than individual prompts and replies. The move targets risks that emerge as AI handles longer-horizon, more autonomous tasks and is intended to guard against malicious users and attacks by misaligned AI agents while remaining compatible with zero-data-retention—customer content will not be accessible to OpenAI. The feature is expected to roll out in September, accompanied by a technical white paper; early tests are underway with Microsoft and Databricks.
