Robust Demand in US 10-Year Treasury Auction Boosts Bond Prices
On Wednesday (New York time), the US Treasury successfully auctioned $39 billion in 10-year Treasuries. The robust demand provided a strong boost to the market amid the backdrop of globally rising long-term yields, alleviating concerns of escalating stock market pressures.
Winning Bid Yield Below Expectations, Strong Demand
The winning bid yield for this 10-year Treasury auction was 4.362%, lower than June’s 4.421%, and slightly below the pre-auction yield (When Issued) of 4.365%, by a margin of 0.3 basis points. This marks the fifth consecutive time the winning yield was below the pre-auction rate but with the smallest difference to date, indicating strong demand for the 10-year Treasuries.
The bid-to-cover ratio was 2.61, higher than June’s 2.52, marking the highest level since April and exceeding the average of 2.56 over the past six auctions, showing significant investor interest in the 10-year Treasuries under the current rate environment.
Internal Subscription Data Shows Variance in Foreign and Domestic Demand
Within the auction structure, the indirect bidding portion was 65.4%, though lower than last month's 70.6%, it remains at a relatively high level, reflecting considerable foreign demand.
Notably, the direct bid portion reached 23.7%, the highest since March 2014, while during the market volatility in April, it dropped to 1.4%, indicating a significant recovery in demand from domestic investors (including hedge funds, pension funds, mutual funds, insurance companies, and banks).
Primary dealers, the "last resort buyers," were allocated 10.9% in this round, slightly above June’s 9.0% but still at historically low levels, underscoring the strong actual market demand.
Key Timing Amid Global Long-End Yield Rise
Analysts note this auction sharply contrasts with Tuesday’s lackluster 3-year Treasury auction, coinciding with globally rising long-end yields, with the 30-year Treasury yield approaching the critical psychological level of 5%. A lack of buying support at this time might lead to further selling pressure in global markets, especially in stocks.
The strong auction effectively boosted Treasury prices for the day, with the 10-year yield falling nearly 7 basis points, erasing all gains for the week, showing a marked improvement in market confidence due to the strong auction.
Market Impact
The strong performance of this 10-year Treasury auction not only buoyed Treasury market sentiment but also provided a temporary cushion for global markets amid upward pressure on long-end yields. As US economic data continues to unfold and global market liquidity dynamics change, investors will closely watch future Treasury auctions and their impact on market yield curves and global capital flows.
