Finance & Markets News Today — September 28, 2026

Global markets are navigating a complex landscape of geopolitics and economic developments. On the diplomatic front, the US and China are taking steps to ease trade tensions, agreeing to lower tariffs on $60 billion worth of goods, which could have far-reaching implications for global trade. Meanwhile, in the energy sector, oil prices are getting a boost after former US President Donald Trump's comments on the Hormuz Strait led to a 2.7% gain in Brent crude prices.

In other news, deal-making is also in focus, with Northern Star Resources seeing its shares surge after the Australian gold miner rejected a $27 billion takeover proposal. This development comes as some high-profile deals are being made outside of the boardroom, such as the listing of a $1.2 million Texas home by Olympic gymnast Simone Biles and her husband Jonathan Owens. As companies and individuals navigate this shifting landscape, tech giants like Nvidia are working to address concerns around emerging technologies, including the release of a new software platform aimed at preventing AI agents from misbehaving.
