走在债市曲线之前系列报告(五):活跃券中的收益挖掘之路
Changjiang Securities· 2025-07-17 04:45
Group 1: Report Highlights - The active bond phenomenon is caused by the differentiation between the allocation portfolio and the trading portfolio. New bonds go through a cycle of "liquidity accumulation → premium widening → switching to active bonds → premium continuing to widen → premium compression" after issuance. The new-old bond spread is an indicator of liquidity premium [4][7]. - For a new bond to become an active bond, it must meet three core conditions: longer maturity, larger scale, and continuous issuance. Other factors such as issuance timing and code convenience can also be considered [4][8]. - The shape of the new-old bond spread shows a divergent evolution trend among bond types. The spread center has shifted downward, the active bond cycle has generally shortened, and the time for the spread to reach its peak has also decreased. In the future, the active bond phenomenon may gradually weaken [4][9][10]. - The new-old bond spread arbitrage strategy can be divided into four stages, and the report calculates the arbitrage space and stop-profit indicators for each stage [4][11]. Group 2: Active Bond Phenomenon - The active bond phenomenon is driven by the pursuit of liquidity by market participants. Each new bond experiences a cycle of strong to weak liquidity, corresponding to the active bond lifecycle. The liquidity premium of active bonds is an important indicator of market sentiment and capital flow and creates multiple trading arbitrage opportunities [20]. - The active bond phenomenon is caused by the differentiation between the allocation portfolio (banks, insurance) and the trading portfolio (funds, securities firms, etc.). The allocation portfolio holds bonds until maturity, weakening the demand for liquidity, while the trading portfolio relies on price difference returns, strengthening the dependence on liquidity [21]. - The active bond is not permanent but changes over time. When a new bond is issued, it may gradually replace the old bond as the new active bond, a process called new-old bond alternation [22]. Group 3: Conditions for New Bonds to Become Active Bonds - Longer maturity: Active bonds need to have sufficient duration sensitivity to attract trading funds for band operations. Long-term bonds (such as 10Y/30Y) are suitable for trading to obtain capital gains due to their long duration and sensitivity to interest rate fluctuations [36]. - Larger scale: Scale is the cornerstone of liquidity. A single bond's circulation volume needs to exceed a certain scale threshold to accommodate high-frequency trading. Large-scale bonds can avoid being "bought out" by the allocation portfolio and provide capacity for short-term leveraged trading [37]. - Continuous issuance: Frequent issuance helps maintain market attention and prevent existing bonds from being marginalized. Interruptions in issuance can lead to a rapid decline in liquidity [43]. - Issuance timing: If a new bond is issued at a relatively high interest rate and continued to be issued during a period of rapid interest rate decline, the switching of active bonds may be hindered. An interest rate shock period is relatively favorable for new bonds to switch to active bonds [50][51]. - Code convenience: Complex codes may increase trading friction costs, while simple codes can improve trading efficiency. Bonds with convenient codes are more likely to attract trading [56]. Group 4: Patterns of New-Old Bond Spread Trends - The new-old bond spread shows regular fluctuations along with the active bond switching cycle, generally presenting an "M-shaped" trend. The spread first widens, then narrows, widens again, and finally converges [62]. - The shape of the new-old bond spread shows a divergent evolution trend among bond types. The 10-year CDB bond shows a trend of changing from an "inverted V-shaped" to an "M-shaped", the 10-year Treasury bond evolves in the opposite direction, and the 30-year Treasury bond maintains an "M-shaped" [9][64]. - The center of the new-old bond spread has shifted downward, and the maximum spread average of the three major bond types has been compressed to varying degrees. The driving factors include the allocation portfolio's continuous increase in holding existing old bonds, the diversion effect of special Treasury bonds on liquidity, and the enhanced consistency of the trading portfolio's pursuit of new bonds [80][83][85]. Group 5: Shortening of Active Bond Cycle and Spread Peak Time - The active bond cycle has generally shortened. The active bond cycles of 10-year Treasury bonds and CDB bonds have been shorter this year due to the faster switching rhythm. The cycle characteristics of 30-year Treasury bonds are mainly reflected in the shorter active cycle of special Treasury bonds [10][89]. - The spread peak usually lags behind the switching date. In recent years, due to the advancement of market expectations, the time for the peak to appear has shortened, reflecting a shift from long-term cyclical to short-term event-driven liquidity premium gaming [10][91]. Group 6: New-Old Bond Spread Arbitrage Strategy - The new-old bond spread arbitrage strategy can be divided into four stages: arbitrage of the primary-secondary market spread from the new bond's payment date to the listing date, arbitrage of the spread widening from the listing date to the "sub-maximum spread day" before the switching date, arbitrage of the spread widening from the switching date to the peak of the active bond spread, and trading of the spread convergence from the peak decline to the retirement of the active bond [11][92]. - From the payment date to the listing date of a new bond, the spread generally widens. A "long new bond, short old bond" strategy can be adopted on the payment date and closed on the listing date to complete short-term arbitrage [93]. - After the new bond is listed, the spread fluctuates in a pattern of "first widening, then a phased correction". A "long new bond, short old bond" strategy can be adopted on the listing date and stopped for profit on the "sub-maximum spread day" [98].

Changjiang Securities· 2025-07-17 01:44
1. Report Industry Investment Rating No relevant content provided in the report. 2. Core View of the Report - The current adjustment of the dividend yield has alleviated the pressure of the over - valued bond market, and the odds have increased marginally. The current cost - performance advantage of bonds is gradually emerging, which may provide a more favorable valuation support environment for the phased layout of interest - rate bonds [7][18]. - The liquidity environment provides a relatively stable operating foundation for the bond market. The social financing growth rate may peak in the third quarter and then decline trend - wise, and the expected impact of structural changes on the bond market is limited. The bond market faces a relatively friendly liquidity environment [7][24]. - The central bank has clearly shown its attitude of protecting liquidity, and the money market is expected to return to a balanced and loose state. The yield of the 10 - year Treasury bond may decline to around 1.6%. It is recommended to pay continuous attention to the yield curve and various convex point opportunities, and the spread may continue to be flattened in late July. It is advisable to first focus on interest - rate bonds and Tier 2 capital bonds, and then on credit bonds [7][34]. 3. Summary by Relevant Catalogs Recent Bond Market Callback - From July 7th to July 16th, the yields of the bond market generally increased. The yields of the 10 - year and 30 - year Treasury bonds increased by 2bp and 3bp respectively, and the short - end yields increased more significantly. The adjustment of Tier 2 capital bonds was more obvious [5][12]. Bond Market Odds Gradually Rising - The adjustment of the dividend yield has alleviated the pressure of the over - valued bond market, and the odds have increased marginally. The decline of the CSI 300 dividend yield from the May average of 3.47% to 3.0% on July 14th is conducive to the inflow of funds into the bond market [7][18]. - The liquidity environment provides a stable foundation for the bond market. The social financing growth rate is expected to reach a high of about 9.0% in July and then decline to around 8.2% by the end of the year. The support of government bonds for social financing may weaken in the fourth quarter, and the substitution effect of special refinancing bonds on RMB loans will continue. The central bank will implement a moderately loose monetary policy, and the bond market's liquidity environment is friendly [7][24]. 10 - year Treasury Bond Has Certain Odds Above 1.65%, Recommend First Interest - rate and Tier 2 Capital Bonds, Then Credit Bonds - Due to the disturbance of the money market at the beginning of the quarter and the strengthening of the equity market, the Tier 2 capital bonds and credit bonds with previously compressed spreads have given back their gains, especially the medium - and long - term and some medium - and low - grade varieties. However, the core logic of Tier 2 capital bonds has not changed [33]. - Since July 10th, the central bank has shifted to net investment in open - market operations. The money market is expected to return to a balanced and loose state, and the yield of the 10 - year Treasury bond may decline to around 1.6%. It is recommended to seize the layout opportunities after the adjustment, with medium - and short - term varieties as the basis for coupon income, and medium - and high - grade 3 - 5 - year varieties having better elasticity in interest - rate band operations [34].
