Pantera Capital founder Dan Morehead said the move didn't stick because $2 billion in fresh buying couldn't counter roughly $2 trillion of annual supply hitting the market. Steven Major, a global macro adviser at Tradition, noted that expectations swung from three rate cuts priced at the start of the year to a hike now, a 100 basis point shift he said explains the move. ## Why gilts sliced the UK's fiscal wiggle room in half Bloomberg Economics estimates that multi-decade highs in gilt yields have cut the government's fiscal headroom in half. That leaves new Prime Minister Andy Burnham with a £12 billion headache before his first Prime Minister's Questions. Burnham used his first appearance in the Commons to promise more public control over water, energy and transport, while his predecessor Keir Starmer said he will resign as an MP and trigger a by-election in Holborn and St Pancras. ## How energy and geopolitics are pushing yields higher Brent crude pushed toward $95, and European TTF gas rose 2.5% to €74 per megawatt hour, more than 70% above early July levels. Markets strategist Mark Cranfield tied the renewed US strikes on Iran to fresh energy jitters, just as investors now expect 5% on the US 10-year to send ripples across global markets. Bessent said China blocked a unanimous G20 finance statement in North Carolina, with 19 members backing open passage through the Strait of Hormuz. Germany, separately, blamed Russia for a failed drone attack at Leipzig airport and closed the Russian consulate in Bonn. ## What Nvidia and Dyson say about AI spending Nvidia is in advanced talks to acquire [Hugging Face](https://www.startuphub.ai/cybersecurity/hackerone-ceo-openai-ai-hack-was-responsible-testing) for around $14 billion, including a $1 billion retention package. Franklin Templeton's Sarah Araghi said Nvidia is backstopping the AI ecosystem because hyperscaler free cash flow can no longer fund the buildout on its own. Dyson showed off an AI toothbrush with an integrated camera and machine learning trained on hundreds of thousands of dental images that fires a burst of mouth rinse at trouble spots. The bond market is no longer debating when cuts return. --- Original analysis from [startuphub.ai](https://www.startuphub.ai), the #1 AI startup directory.
