There are striking parallels between the dramatic recent sell-off in U.S. Treasuries and the Great Bond Crash of 1994. But the summer of volatility now facing financial markets is no doomsday scenario. Instead, it puts the U.S. Federal Reserve in a bind. Higher interest rates will reduce housing affordability, which is especially troublesome since housing is the primary locomotive of U.S. economic growth. That means the Fed, despite Ben Bernanke’s recently announced timetable, may be forced to expand or extend quantitative easing if the housing market’s response to recent events becomes more acute and starts to negatively affect the job market recovery.
