Lehman’s 2008 collapse wasn’t the only time that speculation led to a crisis, and nor would this be the last one. The creation of the US Fed traces back to the Panic of 1907, which was triggered by the Heinze brothers’ failed attempt to corner shares in United Copper resulted in a bank run. Since then, the Fed as a lender of last resort has stepped in regularly to avert crisis in the financial markets. Experts also say that the global financial crisis led to rising inequality, populism, and protests such as Occupy Wall Street. Even the protectionism path that Donald Trump is following has roots in the crisis. Lagarde wrote we are now facing new, post-crisis, fault lines — from the potential roll-back of financial regulation, to the fallout from excessive inequality, to protectionism and inward-looking policies, to rising global imbalances. “How we respond to these challenges will determine whether we have fully internalised the lessons from Lehman. In this sense, the true legacy of the crisis cannot be adequately assessed after 10 years — because it is still being written,” she said.
