Federal Reserve Chairman Greenspan, while at a conference in Germany to discuss the euro, has said those not hedged for higher rates should be prepared to lose money... This is one of the FOMC Chair's most direct comments about the direction of interest rates, and it has caused intense selling in both equities and treasuries... The 10-year note has dropped 21 ticks to yield 4.19%, while the dollar has also extended its losses on Greenspan's comment that "currency interventions have had only moderate effects in the past"...
