For the second day in a row, the yield on the 10-year hovers around 3%.
Some say the move is reflective of the country's economic momentum and could thus be sustainable. The last time yields exceeded the psychologically important threshold was in September, but that move was short-lived.
One senior bond trader quoted by the WSJ thinks yields could hit 3.25% over the next three months. The 10-year hit 3.021% at one point in Friday's session.
