US Treasuries rallied on Thursday after a $22 billion 30-year bond auction drew solid investor demand amid easing geopolitical tensions over Iran.
Yields on 30-year bonds dropped by six basis points to 5.61%, moving away from multi-decade highs recorded in recent weeks.
Long-dated yields extended declines after President Donald Trump indicated a delay in potential military strikes on Iran until after the November 3 midterms.
