Long-term bond yields have reached their highest levels since May due to investor reactions to Donald Trump"s election victory and its potential impact on Federal Reserve policy.

The yield on 30-year bonds has increased by 6 basis points to 4.68%, which is the highest it has been since late May. Similarly, the 10-year bond yield has risen by approximately 3 basis points to 4.47%, reflecting a broader trend of rising yields across Europe.

The increase in yields is also influenced by increased bond supply, with Morgan Stanley announcing a 31-year bond offering. Furthermore, a number of corporate borrowers are expected to enter the market with investment-grade bond sales today, contributing to the upward pressure on yields.
