Treasury Yields Fall After Strong 30-Year Bond Auction
The US government sold $22 billion in bonds that will be paid back over 30 years.
Many investors wanted to buy them, even though the bonds offer high interest payments.
After the sale, prices of Treasury bonds went up and their yields went down.
The yield on 30-year bonds fell to 5.61%.
The Treasury also bought back $6 billion of older bonds.
Investors were watching worries about the Iran war and its possible effects on oil prices and inflation.
President Donald Trump said he would wait until after the US midterms before attacking Iran again.
Oil prices fell from an earlier high, which helped ease some near-term worries.
A $22 billion US auction of 30-year bonds drew solid demand, following a strong 10-year auction earlier in the week.
The 30-year Treasury yield fell six basis points to 5.61%; the auction yield was 5.618%.
Primary dealers received 6.8% of the sale, below their recent 10% average.
The Treasury followed the auction with a $6 billion buyback of bonds maturing in 20 to 30 years.
Yields also fell as oil prices retreated and Trump said he would delay further attacks on Iran until after the Nov. 3 US midterms.
