The yield on the 30-year U.S. Treasury has climbed to its highest level in nearly two decades, but some Wall Street strategists are warning that the selloff in long-term government bonds may have further room to run.

The 30-year Treasury yield rose more than 4 basis points Monday to 5.311%, its highest level since June 2007, according to CNBC.
