Under normal circumstances, a pair of dissents in favor of a rate cut would be taken as a sign the Fed is taking a dovish turn, Tom Essaye, editor of Sevens Report Research, wrote in a Tuesday note. It would be signal that policymakers are moving in favor of easing, making a reduction at the next meeting a more likely event.

The yield on the 10-year hit a 52-week high of 4.896% on January 13, a week before Trump's second inauguration, and traded as low as 3.860% on April 4 before spiking to 4.607% on May 21, then settling at 4.431% on July 18.

The Federal Reserve holds its latest interest rate meeting this week, with policymakers expecting rates to be left unchanged despite President Donald Trump's calls for interest rate cuts.
