“Our financial sector is built on sand,” Michael Lewis, the American author, told me last week. “After all, we’re in the middle of a huge monetary experiment, with central banks playing a bigger role in stimulating growth than we’ve ever seen”.
Back in 2010, Lewis wrote The Big Short – an expose of the banking shenanigans that sparked the 2008 financial crisis. It has since been made into a glitzy Hollywood movie, which enjoyed its UK premier last week.
