CNBC analysis indicates that market sentiment was rattled as the 10-year U.S. Treasury yield surpassed 5% on Tuesday, reaching a new high since 2007. However, the surge from zero rates since the pandemic suggests that the risk-reward in fixed income markets has improved and may be approaching "escape velocity," where bonds can still offer positive returns even in an environment of continuously rising interest rates. Analysts believe that the current higher yields provide a greater buffer, and the risk-reward calculation for intermediate-term bonds (5-10 years) is becoming more favorable for investors.
