Report Industry Investment Rating No relevant content provided. Core View of the Report The bond market has not formed a trend - based market, and it is expected to return to a volatile state after short - term emotional fluctuations. To obtain excess returns in the volatile market, one can first seek assets with relative volatility and liquidity on the curve, and then look for individual bonds with relative value. Currently, 30 - year Treasury bonds are recommended [25]. Summary by Relevant Catalogs This Week's Bond Market Review - This week, the bond market fluctuated sharply. The first half of the week saw a cycle of repair - decline - repair around the performance of the commodity and equity markets and the "anti - involution" policy expectations. The second half was initially stabilizing but was hit by a sharp volatility at the end of Friday due to tax policy changes. However, the 10 - year Treasury yield remained in a narrow range of 1.70% - 1.75% [1][9]. - From 25th July to 1st August, the yields of 1 - year, 5 - year, 10 - year, and 30 - year Treasury bonds decreased by 1.0BP, 3.6BP, 2.7BP, and 2.3BP respectively [11]. Next Week's Key Bond Market Concerns - A sudden change in the tax system for Treasury bonds occurred on Friday night. Next week, the bond market will first price this event. "New bonds" refer to those issued on or after 8th August with new codes, while "old bonds" are those existing before this date, including active and non - active ones [18]. - Next week, the focus is on the allocation desks' scramble for active old bonds. Old bonds may be more popular among allocation desks due to tax advantages. Non - active bonds are already concentrated in allocation desks with limited liquidity, so it is expected that allocation desks will target active old bonds. Trading desks may sell at this time and wait to trade new bonds later. Also, trading desks may increase purchases of short - term credit bonds and certificates of deposit in the short term [2][19]. - Bond yields are expected to quickly price the scramble behavior next week. The spread between new and old bonds is expected to be smaller than the static calculation result. Old bonds will have a liquidity discount after being held by allocation desks, and some institutions are insensitive to tax rates [2][20]. Next - Stage Strategy Considerations - The bond market is in a volatile state and has not shown a trend reversal. To gain excess returns, one can first find assets with relative volatility and liquidity on the curve and then look for individual bonds with relative value. Currently, 30 - year Treasury bonds are recommended [25]. - The ultra - long end of the curve has volatility and opportunities. In the second quarter, ultra - long bonds created relative volatility in a "sideways" market. They are more sensitive to short - term factors. Since the second quarter, the intraday amplitude of the 30 - year Treasury active bond was higher than that of the 10 - year Treasury active bond on 60 out of 84 trading days [25]. - After the bond market adjustment in mid - to - late July, the spread of ultra - long - end interest - rate bonds has widened. As of 1st August, the 30 - year - 10 - year Treasury spread was 24BP, at the 90% percentile in the past year [34]. - In August, there will be issuance disturbances for ultra - long bonds. After the issuance of the 50 - year special Treasury bond on 1st August, 3 more ultra - long special Treasury bonds are to be issued. With the expected reduction of the预定 interest rate in September and the possible scramble for old bonds by insurance companies after the tax reform, the allocation demand for ultra - long bonds is expected to be strong [4][36]. - During the issuance of ultra - long bonds, the relative value of individual bonds will change. If the issuance scale of "25 Special Treasury 05" on 8th August remains the same as the previous two issues, its scale will reach 24.9 billion yuan. It may become the second - most active bond, and the yields of the three bonds are expected to converge, with the yield of "25 Special Treasury 02" possibly decreasing by about 2BP [5][37].
