AI mania may be driving markets to new heights, but economist and author Dambisa Moyo argues the real question isn’t whether we’re in a tech-driven bubble—it’s what stage. Speaking with Merryn Somerset Webb, Moyo says that while valuations look stretched and investor excitement is unmistakable, there may still be a ways to go before things get bad.

Turning to the UK, Moyo, a member of the House of Lords, argues that the country’s central challenge is weak growth, held back by two chokepoints: high energy costs and underperforming capital markets that fail to attract investment or nurture emerging companies. What’s needed, she says, is not just policy fixes but a stronger, more optimistic national story that makes the UK a natural magnet for capital.
