The typical career of a Wall Street banker lasts about a quarter of a century, enough to span just one big financial crisis. As Niall Ferguson explains in his new book, "The Ascent of Money", which will be published next month, today's senior financiers would have started out in 1983, fully ten years after oil and gold prices first began the surge that had ruined the previous generation of money men. That, he concludes, is a "powerful justification for the study of financial history."rnMr Ferguson is right. The world needs a book that puts today's crisis into context. It is too late now to warn investors about expensive houses and financiers about cheap credit. But perhaps the past can help make sense of the wreckage of banks, brokers and hedge funds that litters the markets. Looking back may help suggest what to do next. And when the crisis is over and it is time for the great reckoning, the lessons of history should inform the arguments about what must change.
