[Strong Demand for U.S. 30-Year Treasury Auction, Long-Term Yields Retreat from Intraday Highs] Reported by Golden Finance, on September 11, the $22 billion U.S. 30-year Treasury auction saw strong demand, providing some relief to the long-term U.S. Treasury market for the second consecutive day. The auction yield came in lower than traders had previously expected, indicating robust investor demand. According to the Bank of Montreal (BMO), the proportion of primary dealers required to participate in bidding dropped to a historic low, suggesting that more bonds were purchased by end investors. Following the auction, the yield on 30-year U.S. Treasuries saw the largest decline, falling to around 5.33%, though it still rose significantly for the day. Meanwhile, the 10-year yield remained roughly flat at 4.924%. Short-term U.S. Treasuries were not boosted by the auction; their yields continued to rise slightly, indicating that the strong demand primarily alleviated selling pressure on long-term bonds. Recently, long-term U.S. Treasuries have been under pressure due to concerns over fiscal deficits, debt supply, and inflation.
