During the mid-2000s, many forms of collateral around the world were either implicitly or explicitly backed by U.S. residential land. As I’ve described, beginning in mid-2007, it became clear that this asset had more risk than financial markets had originally appreciated. It was not clear, though, how much more risk was involved. As a result, financial markets became increasingly uncertain about how to evaluate assets backed by U.S. land. That uncertainty translated into uncertainty about the ultimate solvency of institutions holding those assets—and the ultimate solvency of any of those institutions’ creditors. Spreads in credit markets between Treasury returns and other bond returns began to widen—at first slightly and then alarmingly.
