How Cooking the Books on Inflation Helped Destroy the Global Economy

In the Wall Street Journal, Steven Gjerstad and Vernon Smith explain a key difference between the crash that followed the burst of the 1996-2006 housing bubble, and earlier bubbles that didn't bring the whole enchilada down with them when they deflated [HT: The Bubble Meter].

Monetary policy is a key part of the story -- monetary policy that created the appearance of prosperity, even as American families were growing more financially insecure year after year.

The Fed, under Clinton and Bush, kept interest rates at very low levels even after the recession that followed the crash of the dot-com bubble in the early 2000s. Combined with the elimination of capital gains for houses sold for less than a half-million dollars, the result was a lot of cheap money out there gravitating to one of the few sectors of the economy that was growing.

In just the past 40 years there were two other housing bubbles, with peaks in 1979 and 1989, but the largest one in U.S. history started in 1997, probably sparked by rising household income that began in 1992 combined with the elimination in 1997 of taxes on residential capital gains up to $500,000. Rising values in an asset market draw investor attention; the early stages of the housing bubble had this usual, self-reinforcing feature.

The 2001 recession might have ended the bubble, but the Federal Reserve decided to pursue an unusually expansionary monetary policy in order to counteract the downturn. When the Fed increased liquidity, money naturally flowed to the fastest expanding sector. Both the Clinton and Bush administrations aggressively pursued the goal of expanding homeownership, so credit standards eroded. Lenders and the investment banks that securitized mortgages used rising home prices to justify loans to buyers with limited assets and income. Rating agencies accepted the hypothesis of ever rising home values, gave large portions of each security issue an investment-grade rating, and investors gobbled them up.

On that last point, the authors gloss over a key point. As the NY Times reported last year, "Credit rating agencies did not properly manage their conflicts of interests when assigning ratings to structured products such as mortgage-backed securities, a report by the Securities and Exchange Commission said on Tuesday." But that's an aside ...

But housing expenditures in the U.S. and most of the developed world have historically taken about 30% of household income. If housing prices more than double in a seven-year period without a commensurate increase in income, eventually something has to give. When subprime lending, the interest-only adjustable-rate mortgage (ARM), and the negative-equity option ARM were no longer able to sustain the flow of new buyers, the inevitable crash could no longer be delayed.

How did we get there?
