“There are two bubbles: We have a stock market bubble, and we have a bond market bubble,” Alan Greenspan, 91, said Wednesday on Bloomberg Television with Tom Keene and Scarlet Fu. Greenspan, who led the Federal Reserve from 1987 until 2006, memorably used the phrase to describe asset values during the 1990’s dot-com bubble.
Greenspan’s comments come as stock indexes remain near record highs, despite selling off in recent days, and as the yields on government notes and bonds hover not far from historic lows. Interest rates are expected to move up in coming years as the Fed continues with a campaign to gradually tighten monetary policy.
“At the end of the day, the bond market bubble will eventually be the critical issue, but for the short term it’s not too bad,” Greenspan said. “But we’re working, obviously, toward a major increase in long-term interest rates, and that has a very important impact, as you know, on the whole structure of the economy.”
