LESS than a decade ago ING Group, with its orange lion logo, was the epitome of finance rampant. Its banking, insurance and asset-management activities sprawled across the globe. Today, as it emerges early from a state bail-out precipitated by its large portfolio of American mortgages, it is again an example—this time of the sort of institution that new, more demanding prudential rules encourage. ING is now almost entirely a bank, more focused than before on Europe, with total income in 2013 around a third of that in 2007. While rivals such as Commerzbank or Royal Bank of Scotland still struggle to adapt to the new regulatory strictures, ING is ready to roll.
