The Great Crash of 1929 has faded into history, but financial journalist and author Andrew Ross Sorkin argues it holds vital lessons for today.

Andrew came into the studio in London to discuss what we can understand about the crash in numbers, from ticker-tape running hours behind plunging stock prices to crucial metrics that sound the alarm bells before a financial crisis. Are they sounding today, in the middle of an AI stockmarket boom?

Andrew’s new book is ’1929: Inside the Crash’.
