NEW YORK (MONEY Magazine) - If a high-yield savings account sounds like an oxymoron, get ready for a pleasant surprise: After the Federal Reserve's marathon of interest-rate hikes since mid-2004, short-term rates hover around 4.5 percent, while long-term yields have stayed the same, at times even dipping below shorter-term ones -- an unusual relationship that economists call an inverted yield curve.

What that means for you: You can get some of the highest yields around in some of the safest investments there are -- savings and money market accounts.
