Core Viewpoint - The U.S. Treasury bonds closed mixed on Wednesday, with the 7-year yield remaining stable, influenced by the quarterly refinancing announcement, which met expectations and showed no significant changes in the Treasury's debt issuance strategy [1][7]. Yield Movements - Short-term yields decreased by less than 1 basis point, while long-term yields increased by approximately 2 basis points, leading to a steepening of the yield curve [1][7]. - The 10-year U.S. Treasury yield closed at 4.275%, essentially unchanged, while the 10-year German bonds outperformed U.S. bonds by 4 basis points, and the U.K. bonds underperformed by 2 basis points [1][7]. Spread Changes - The 2s10s and 5s30s yield spreads both steepened by about 2 basis points during the day [1][7]. - The spread between the 2-year and 10-year Treasury yields increased by 2.03 basis points to 71.41 basis points [12]. - The spread between the 5-year and 30-year Treasury yields rose by 1.97 basis points to 107.888 basis points [12]. Market Reactions - Following the refinancing announcement, U.S. Treasury bonds began to exhibit a steepening trend, and the dollar swap spreads subsequently narrowed, indicating that some positions betting on widening spreads were unwound [1][7]. - Recent flows related to hedging by financial firms issuing bonds also contributed to the narrowing of spreads this week [8]. Economic Indicators - The services PMI and ISM services index showed robust performance, with limited reaction from U.S. Treasury bonds, as the market maintained expectations for cumulative rate cuts of about 50 basis points by the end of the year [8].
