Inverted Yield curve for bonds?

[Roger_R]

I'm certainly not a bond expert, but as close as I can figure long term rates are bound to inch upwards, or the yield curve for bonds will become inverted. Check my logic. The yields for short term and intermediate term CD's per ING and other sources seem almost flat. Greenspan has continued to insist that short term rates will rise at a measured pace. Additionally Greenspan has made some rather cloaked references and concerns to high housing prices. Higher long term rates are one thing that could temper RE prices.

I've done my best trying not to second guess intermediate or longer term bond rates, but it just seems to my that something has to give. Though maybe slowly. The alternative is an inverted yield curve which historically has been a predictor of recession.
