Regulators must also work together, she added, amid evidence that some countries are caving into pressure from the banking lobby. “Financial sector reform efforts must be coordinated internationally. We are already seeing countries pulling in different directions in some areas, such as in calculating the riskiness of assets and curbing banking excesses,” Ms Lagarde said.
The eurozone has yet to grapple with its banking problems convincingly, which is harming efforts to revive growth in the region.
“Especially in the periphery, many banks are still in an early stage of repair – not enough capital and too many bad loans on their books. Even outside the periphery, there is a need to shrink balance sheets, reduce reliance on wholesale funding, and improve business models,” she said.
Because the banks are broken, cheap credit is not getting through to the parts of the economy that need it. “Because of insufficient financial repair, monetary policy is “spinning its wheels” – meaning that low interest rates are not translating into affordable credit for people who need it,” she said.
“So the priority must be to continue to clean up the banking system by recapitalising, restructuring, or – where necessary – shutting down banks.” One option for eurozone would be “direct recapitalisation by the European Stability Mechanism”, the region’s bail-out fund, she added.
The UK is leading the field on bank reform, with the Bank of England last month demanding lenders find another £25bn of capital despite already being far better capitalised than European peers.
Ms Lagarde's comments came as she said the global economy was improving and “no longer looks quite as dangerous as it did six months ago”. The world is now in a three speed recovery of countries doing well, such as the emerging markets, those “on the mend, like the US, and those that “still have some distance to travel”, like the eurozone.
“We know the future we want. We know the path to get there. The task before us now is to act, to make that future a reality, to get ahead – and stay ahead – of the crisis,” she said.
