In this week's Markets Happy Hour Podcast (our second recorded this week - there will be a special episode featuring Paula Campbell Roberts from KKR released shortly), we focus on recent rumbles in markets around the integrity of the AI story, the increased concern about power costs and how our "discovery phase" around Bitcoin is continuing, with more and more clues added weekly.We start with the usual inflation analysis and the strain that power costs are likely to have for the lower income consumer. Fixed income volatility continues to be subdued, even among government bonds which suggests an interesting sense of calm among a cohort (bond investors) which continues even in the government bond arena.Equity markets continue to be rattled by the scope of spending on AI infrastructure as well as some high profile shorting in the space, and it is worth recalling three hallmarks of bubbles - as suggested by a Financial Times journalist - Leverage, Liquidity and Lunacy. We trace each of these with reference to the current market context.Finally we examine recent behavior in Bitcoin and see how it has decoupled from gold and ask what this tells us about its characteristics as an asset class.
