Many of Minsky’s colleagues regarded his “financial-instability hypothesis,” which he first developed in the nineteen-sixties, as radical, if not crackpot. Today, with the subprime crisis seemingly on the verge of metamorphosing into a recession, references to it have become commonplace on financial Web sites and in the reports of Wall Street analysts. Minsky’s hypothesis is well worth revisiting. In trying to revive the economy, President Bush and the House have already agreed on the outlines of a “stimulus package,” but the first stage in curing any malady is making a correct diagnosis.
Minsky, who died in 1996, at the age of seventy-seven, earned a Ph.D. from Harvard and taught at Brown, Berkeley, and Washington University. He didn’t have anything against financial institutions—for many years, he served as a director of the Mark Twain Bank, in St. Louis—but he knew more about how they worked than most deskbound economists. There are basically five stages in Minsky’s model of the credit cycle: displacement, boom, euphoria, profit taking, and panic. A displacement occurs when investors get excited about something—an invention, such as the Internet, or a war, or an abrupt change of economic policy. The current cycle began in 2003, with the Fed chief Alan Greenspan’s decision to reduce short-term interest rates to one per cent, and an unexpected influx of foreign money, particularly Chinese money, into U.S. Treasury bonds. With the cost of borrowing—mortgage rates, in particular—at historic lows, a speculative real-estate boom quickly developed that was much bigger, in terms of over-all valuation, than the previous bubble in technology stocks.
As a boom leads to euphoria, Minsky said, banks and other commercial lenders extend credit to ever more dubious borrowers, often creating new financial instruments to do the job. During the nineteen-eighties, junk bonds played that role. More recently, it was the securitization of mortgages, which enabled banks to provide home loans without worrying if they would ever be repaid. (Investors who bought the newfangled securities would be left to deal with any defaults.) Then, at the top of the market (in this case, mid-2006), some smart traders start to cash in their profits.
The onset of panic is usually heralded by a dramatic effect: in July, two Bear Stearns hedge funds that had invested heavily in mortgage securities collapsed. Six months and four interest-rate cuts later, Ben Bernanke and his colleagues at the Fed are struggling to contain the bust. Despite last week’s rebound, the outlook remains grim. According to Dean Baker, the co-director of the Center for Economic and Policy Research, average house prices are falling nationwide at an annual rate of more than ten per cent, something not seen since before the Second World War. This means that American households are getting poorer at a rate of more than two trillion dollars a year.
