From NY Fed President William Dudley’s commencement speech at New College of Florida: [T]he recovery is not likely to be as robust as we would like for several reasons. First, households are still in the process of deleveraging. The housing boom created paper wealth that households borrowed against. This pushed the consumption share of nominal gross domestic product to a record high of about 70 percent. When the boom turned into a bust, those paper gains evaporated. In fact, many households now find that the value of their homes is less than the amount of their mortgage debt. This has created a difficult time for many families and has caused the hangover to last longer. Second, the banking system is still under significant stress.
