Interest rates are in somewhat of a holding pattern here ahead of key data -- April new and existing home sales tomorrow and Thursday, and personal income and spending on Friday. One force that seems to be keeping a lid on yields in the short term -- sickly trading in stocks both overseas and here in the U.S. Volatility is rising and fear is creeping in. So you're seeing "flight to safety" buying in bonds. Doesn't impact the longer-term fundamentals, but it is what it is.
