Did the Fed Cause the Housing Bubble?

Don't Blame Greenspan

By David Henderson

It's become conventional wisdom that Alan Greenspan's Federal Reserve was responsible for the housing crisis. Virtually every commentator who blames Mr. Greenspan points to the low interest rates during his last few years at the Fed.

The link seems obvious. Everyone knows that the Fed can drive interest rates lower by pumping more money into the economy, right? Well, yes. But it doesn't follow that that's why interest rates were so low in the early 2000s. Other factors affect interest rates too. In particular, a sudden increase in savings will drive down interest rates. And such a shift did occur. As Mr. Greenspan pointed out on this page on March 11, there was a surge in savings from other countries. Although he names only China, some of the Middle Eastern oil-producing countries were also responsible for much of this new saving. Shift the supply curve to the right and, wonder of wonders, the price falls. In this case, the price of saving and lending is the interest rate.

But how do we know that it was an increase in saving, not an increase in the money supply, that caused interest rates to fall? Look at the money supply.

Since 2001, the annual year-to-year growth rate of MZM (money of zero maturity, which is M2 minus small time deposits plus institutional money market shares) fell from over 20% to nearly 0% by 2006. During that time, M2 (which is M1 plus time deposits) growth fell from over 10% to around 2%, and M1 (which is currency plus demand deposits) growth fell from over 10% to negative rates.

The annual growth rate of the monetary base, the magnitude over which the Fed has the most control, fell from 10% in 2001 to below 5% in 2006. Moreover, nearly all of the growth in the monetary base went into currency, an increasing proportion of which is held abroad.

Moreover, if the Fed was the culprit, why was the housing bubble world-wide? Do Mr. Greenspan's critics seriously contend that the Fed was responsible for high housing prices in, say, Spain?

This is not to say that the Greenspan Fed was blameless. Particularly disturbing is the way the lender-of-last-resort function has increased moral hazard, a trend to which Mr. Greenspan contributed and which current Fed Chairman Ben Bernanke has put on steroids.

But to the extent that the federal government is to blame, the main fed culprits are the beefed up Community Reinvestment Act and the run-amok Fannie Mae and Freddie Mac. All played a key role in loosening lending standards.

I'm not claiming that we should have a Federal Reserve. We simply can't depend on getting another good chairman like Mr. Greenspan, and are more likely to get another Arthur Burns or Ben Bernanke. Serious work by economists Lawrence H. White of the University of Missouri, St. Louis, and George Selgin of West Virginia University makes a persuasive case that abolishing the Fed and deregulating money would improve the macroeconomy. I'm making a more modest claim: Mr. Greenspan was not to blame for the housing bubble.

What Savings Glut?

By Gerald P. O'Driscoll Jr.

Alan Greenspan responded to his critics on these pages on March 11. He singled out an op-ed by John Taylor a month earlier, "How Government Created the Financial Crisis" (Feb. 9), for special criticism. Mr. Greenspan's argument defending his policy is two-fold: (1) the Fed controls overnight interest rates, but not "long-term interest rates and the home-mortgage rates driven by them"; and (2) a global excess of savings was "the presumptive cause of the world-wide decline in long-term rates."

Neither argument stands up to scrutiny. First, Mr. Greenspan writes as if mortgages were of the 30-year variety, financed by 30-year money. Would that it were so! We would not be in the present mess. But the post-2002 period was characterized by one-year adjustable-rate mortgages (ARMs), teaser rates that reset in two or three years, etc. Five-year ARMs became "long-term" money.

The Fed only determines the overnight, federal-funds rate, but movements in that rate substantially influence the rates on such mortgages. Additionally, maturity-mismatches abounded and were the source of much of the current financial stress. Short-dated commercial paper funded investment banks and other entities dealing in mortgage-backed securities.

Second, Mr. Greenspan offers conjecture, not evidence, for his claim of a global savings excess. Mr. Taylor has cited evidence from the IMF to the contrary, however. Global savings and investment as a share of world GDP have been declining since the 1970s. The data is in Mr. Taylor's new book, "Getting Off Track."

The former Fed chairman also cautions against excessive regulation as a policy response to the crisis. On this point I concur. He does not directly address, however, the Fed's policy response. From the beginning, the Fed diagnosed the problem as lack of liquidity and employed every means at its disposal to supply liquidity to credit markets. It has been to little avail and, in the process, the Fed has loaded up its balance sheet with dubious assets.

The credit crunch continues because many banks are capital-impaired, not illiquid. Treasury's policy shifts and inconsistencies under both administrations have sidelined potential private capital. Treasury became the capital provider of last resort. It was late to recognize the hole in banks' balance sheets and consistently underestimated its size. The need to provide second- and even third-round capital injections proves that.

In summary, Fed policy did help cause the bubble. Subsequent policy responses by that institution have suffered from sins of commission and omission. As Mr. Taylor argued, the government (including the Fed) caused, prolonged, and worsened the crisis. It continues doing so.
