Two parallel real estate bubbles emerged in the United States between 2004 and 2008, one in residential real estate, the other in commercial real estate. The residential real estate bubble has received a great deal of popular, scholarly, and policy attention. The commercial real estate bubble, in contrast, has largely been ignored.
This Article explores the causes of the commercial real estate bubble. It shows that the commercial real estate price bubble was accompanied by a change in the source of commercial real estate financing. Starting in 1998, securitization became an increasingly significant part of commercial real estate financing. The commercial mortgage securitization market underwent a major shift in 2004, however, as the traditional buyers of subordinated commercial real estate debt were outbid by collateralized debt obligations (CDOs). Savvy, sophisticated, experienced commercial mortgage securitization investors were thus replaced by investors who merely wanted “product” to securitize. The result was a noticeable decline in underwriting standards in commercial mortgage backed securities that contributed to the commercial real estate price bubble.
The commercial real estate bubble holds important lessons for understanding the residential real estate bubble. Unlike the residential market, there is almost no government involvement in commercial real estate. The existence of the parallel commercial real estate bubble presents a strong challenge to explanations of the residential bubble that focus on government affordable housing policy, the Community Reinvestment Act, and the role of Fannie Mae and Freddie Mac. Instead, the changes in commercial real estate financing closely mirror changes in the residential real estate financing, which shifted from regulated government-sponsored securitization to unregulated private securitization. This indicates that changes in the securitization market contributed to the problems in both the commercial and residential real estate markets.
