President Trump has hailed what he calls a 'morally binding' document on AI guardrails in the face of growing safety concerns - and has signed an executive order to rename the technology after a luncheon with tech leaders at the White House. Meanwhile OpenAI CEO Sam Altman tells CNBC that the firm needs to improve its models safely and confidently before it goes public. And another day, another new high for yields: The yield on 30-year U.S. paper hits its highest in nearly 25 years, as the global bond sell-off continues - with September one of the worst months for sovereigns in years.
