Later on, Congress demanded that thrifts obtain a bank charter by 1998. This was not too onerous for most of them. At the height of the crisis the ratio of their combined equity to their combined assets was less than 1%. But in 1994 it reached almost 10% and remained there ever since. This remarkable turnaround was the result of serendipity as much as careful planning. Interest rate spreads became highly positive. In a classic arbitrage, savings and loans paid low interest on deposits and invested the money in high yielding government and corporate bonds. The prolonged equity bull market allowed thrifts to float new stock at exorbitant prices. As the juridical relics of the Great Depression - chiefly amongst them, the Glass-Steagall Act - were repealed, banks were liberated to enter new markets, offer new financial instruments, and spread throughout the USA. Product and geographical diversification led to enhanced financial health. But the very fact that S&L's were poised to exploit these opportunities is a tribute to politicians and regulators alike - though except for setting the general tone of urgency and resolution, the relative absence of political intervention in the handling of the crisis is notable. It was managed by the autonomous, able, utterly professional, largely a- political Federal Reserve. The political class provided the professionals with the tools they needed to do the job. This mode of collaboration may well be the most important lesson of this crisis. III. Case Study - Wall Street, October 1929 Also published by United Press International (UPI) Claud Cockburn, writing for the "Times of London" from New-York, described the irrational exuberance that gripped the nation just prior to the Great Depression. As Europe wallowed in post-war malaise, America seemed to have discovered a new economy, the secret of uninterrupted growth and prosperity, the fount of transforming technology: "The atmosphere of the great boom was savagely exciting, but there were times when a person with my European background felt alarmingly lonely. He would have liked to believe, as these people believed, in the eternal upswing of the big bull market or else to meet just one person with whom he might discuss some general doubts without being regarded as an imbecile or a person of deliberately evil intent-some kind of anarchist, perhaps". The greatest analysts with the most impeccable credentials and track records failed to predict the forthcoming crash and the unprecedented economic depression that followed it. Irving Fisher, a preeminent economist, who, according to his biographer-son, Irving Norton Fisher, lost the equivalent of $140 million in today's money in the crash, made a series of soothing predictions. On October 22 he uttered these avuncular statements: "Quotations have not caught up with real values as yet ... (There is) no cause for a slump ... The market has not been inflated but merely readjusted..".
