Some of the biggest figures in finance, from the CEO of JPMorganChase to the Governor of the Bank of England, have been warning of potential shocks to the global economy.

As excitement continues to build about the transformative potential of Artificial Intelligence, the US stock market has boomed, potentially forming a fragile bubble. Meanwhile, recent bankruptcies in America have raised worries that a rapid growth in lending by private companies (so-called shadow banks) might be built on shaky ground - and have invoked memories of the subprime mortgage debacle that kicked off the Great Financial Crisis in 2007. And if that wasn’t enough, the threat that Donald Trump might reignite his tariff-driven trade war still looms over the global economy.
