Bond yields are falling, with no end in sight — yet.
The question of just how low U.S. Treasury bonds could go was once met with the expectation of "zero," but now it's not even clear they would stop there.

Both the U.S. 10-year Treasury yield and the 30-year Treasury yield, at 1.35 percent and 2.12 percent Wednesday morning before markets opened, are hovering near all-time lows. Several key market experts, including Allianz chief economic adviser Mohamed El-Erian, believe the U.S. 10-year Treasury yield could slip below the 1 percent mark
