On this week's Merryn Talks Money podcast, host Merryn Somerset Webb speaks with financial historian Edward Chancellor about how energy constraints and geopolitical tensions could reshape markets, whether the artificial intelligence boom is a bubble and what it all means for interest rates. Chancellor argues that AI enthusiasm may be overextended, warns of rising long-term rates and sovereign debt risks and makes the case for gold, commodities, Japan and emerging markets over bonds and expensive growth stocks.
