1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The sharp adjustment of the bond market this week is still a short - term emotional shock, and the pricing logic of assets has not changed much. The upward momentum of the 10 - year Treasury bond rate breaking through 1.75% will weaken marginally, but the downward space for interest rates is also limited. In the face of fluctuations, investors should choose trading strategies carefully according to their liability - side stability and safety cushion [2][17][32]. 3. Summary by Relevant Catalogs 3.1 This Week's Bond Market Review: Risk Assets Continuously Suppress, Curve Bear - Steepens - The Shanghai Composite Index strongly broke through the key points of 3674 and 3700, boosting market risk appetite and leading to a significant adjustment in the bond market. Economic data in July, single - month negative credit growth, and the central bank's outright reverse repurchase operations failed to drive the bullish power of the bond market. By Friday, the yields of 10Y and 30Y Treasury active bonds reached 1.7490% and 1.9980% respectively, approaching key levels [1][8]. - From Monday to Friday, influenced by factors such as the performance of risk assets, policy expectations, and economic data, the yields of 10Y and 30Y Treasury active bonds fluctuated. Compared with August 8th, by August 15th, the yields of 1Y, 5Y, 10Y, and 30Y Treasury bonds increased by 1.6BP, 4.9BP, 5.7BP, and 8.7BP respectively [8][9][10]. 3.2 Before the Key Resistance Level, the "Catalysts" and "Risk Points" of the Bond Market Catalysts - The limited bullish power in the bond market after the release of social financing and economic data this week may be due to the significant decline in bill rates at the end of June, which has already been expected by the market, rather than the unimportance of fundamental factors [2][17]. - The central bank closely monitors and precisely regulates the money market. Although there was a continuous net withdrawal from Monday to Thursday, the money market rate remained stable. On Friday, a 5000 - billion - yuan outright reverse repurchase was implemented in time, and the central bank's open - market operations turned to net injection [17]. - The allocation demand is gradually increasing. Since August is the "sales rush" period before the reduction of insurance's预定 interest rate, the subsequent insurance purchase strength is expected to further increase [17]. Risk Points - There is a risk of negative feedback from bond - fund redemptions. As of August 17th, the scale of stock - funds and bond - funds in August increased by 145.7 billion yuan and 50.3 billion yuan respectively compared with the previous month, and it is the second consecutive month that the growth rate of stock - fund scale is greater than that of bond - funds [3][19]. - The central bank's monetary policy focuses on multiple goals and may tolerate fluctuations in the money market and the bond market caused by the temporary amplification of supply - demand frictions at individual times [4][28]. - Compared with the stock - bond seesaw effect after the "924" package of policies last year, the upward range of interest rates in this round is not large. Since the "anti - involution" market in early July, the yields of 10Y and 30Y Treasury active bonds have increased by 11BP and 15BP respectively [4][28]. 3.3 Strategy Thinking: Ultra - Long Bonds Will See Intensive Issuance, Focus on the Switch of Individual Bond Relative Values - In the unstable bond - market situation, investors are advised to focus on bonds with both liquidity and relative value and conduct refined bond selection. They can seize the trading opportunities brought by the intensive issuance of ultra - long bonds from August to September [5][33]. - Usually, in the early stage of the issuance and subsequent re - issuance of new bonds, the spread between new and old bonds will widen. Next Friday, the 30 - year "25 Ultra - Long Special Treasury Bond 06" will be issued for the first time [5][33]. - Based on the issuance of 11 30 - year Treasury bonds since 2021, the spread between new and old bonds will reach its peak 2 - 9 trading days after the listing of the first - issued bond (except for 250002), with the spread widening by 2.1 - 9.5BP compared with the issuance start date and 1.6 - 15.8BP compared with the listing date (except for 2500005 which is narrowing). For the first issuance and the first two re - issuances, the spreads of active bonds, sub - active bonds, and new bonds compared with the 10 - year Treasury bond rate usually compress within the listing day and the following three trading days [5][34]. - For trading desks that can short, they can short old bonds before issuance, buy new bonds in the primary market, and then sell new bonds and buy back old bonds after the spread between new and old bonds widens. For allocation desks that cannot short, they can sell old bonds in their current holdings before issuance, buy new bonds in the primary market, and decide whether to sell and buy back old bonds after the new bonds are listed. In addition, lending bonds can further increase returns [38].

Group 1 - The bond market has shown a trend of narrowing volatility, influenced by factors such as weakening pressure from risk assets and seasonal liquidity easing [2][7][8] - The implementation of VAT adjustments on August 8 has led to the issuance of nine new local bonds, with results exceeding expectations, indicating a theoretical yield spread of about 10 basis points [3][24] - The actual yield spread between new and old bonds was approximately 4-7 basis points, reflecting a market pricing of around 3% VAT [3][25] Group 2 - The pricing reflects that the 6% VAT has not been fully absorbed by demand nor translated into increased fiscal interest expenses, primarily due to enhanced coordination between monetary and fiscal policies [4][27] - The adjustment in the curve compilation scheme means that new bonds will be given higher weight in valuation, impacting institutions managing net worth [4][28] - Institutions may shift their holdings towards new or actively traded bonds to mitigate potential mark-to-market losses from valuation discrepancies [4][29] Group 3 - The bond market is expected to continue in a volatile pattern, with a focus on structural opportunities, particularly in long-term bonds like the 30-year treasury [5][30] - The current yield spreads for various maturities indicate significant potential for capital gains, especially in the long end of the curve [5][31] - The relative value switching based on market issuance conditions is crucial for fine-tuning bond selection strategies [5][31]

Report Industry Investment Rating No relevant content provided. Core Viewpoints - The anti - involution policy catalyzes the rise of risk appetite, and most treasury bond futures closed higher. The market is affected by macro - policies, inflation, and the new policy of restoring VAT on the interest income of treasury bonds. There is an obvious "new - old bond spread" in the market. The repurchase rate has declined, and the price of treasury bond futures fluctuates. For the 2509 contract, it is neutral. Attention should be paid to the widening of the basis, and short - sellers can use far - month contracts for appropriate hedging [1][2][3]. Summary by Directory I.

IV. Spread Overview - **New - Old Bond Spread**: Due to the new policy of restoring VAT on the interest income of treasury bonds issued by the Ministry of Finance and the State Taxation Administration on August 1, from August 8, all newly - issued treasury bonds, local bonds, and financial bonds need to pay VAT. Coupled with the tax exemption for existing bonds, there is an obvious "new - old bond spread" in the market [2]. V.

Summary of Key Points from the Conference Call Industry Overview - The conference call discusses the impact of the new value-added tax (VAT) policy on the bond market, specifically focusing on government bonds, local government bonds, and financial bonds [1][2][3]. Core Insights and Arguments - The restoration of VAT on government bonds aims to address market distortions caused by previous tax exemptions, which led to increased short-term trading and market volatility [1][3]. - The new VAT rates are set at 6% for proprietary accounts and 3% for asset management products, including public funds, which narrows the tax gap between these entities [1][6]. - The expected impact on the yield spread between new and old bonds is estimated to be between 5 to 10 basis points, although actual changes may be less due to shared tax burdens between buyers and sellers [1][5][7]. - The new tax policy may reduce market enthusiasm for new bonds due to increased costs, but higher coupon rates on new bonds will require investors to weigh the benefits against the costs [9]. - The credit bonds will not see changes in income tax policies, leading to a narrowing of the yield spread between credit bonds and other types of bonds due to the increase in yields for government, local government, and policy bank bonds [8]. Additional Important Content - The new policy is expected to have limited direct effects on fiscal revenue, as it primarily targets new bond issuances while existing bonds retain their tax-exempt status until maturity [3][4]. - The market anticipates that the yield spread between new and old bonds will widen, but the actual increase may be 3 to 5 basis points lower than theoretical estimates due to the shared tax burden [7]. - The introduction of the new VAT policy may lead to a shift in asset allocation, with funds potentially moving from the bond market to dividend stocks, especially in light of the Federal Reserve's interest rate cut expectations [11]. - There is a risk that the tax exemption for public funds may be gradually removed, which could significantly impact the market, although any changes are expected to be implemented slowly [12]. Conclusion - The new VAT policy on bonds is a significant regulatory change that aims to improve market efficiency but may also lead to shifts in investor behavior and asset allocation strategies. The implications for public funds and the overall bond market dynamics warrant close monitoring.

Core Viewpoint - The People's Bank of China conducted a 7-day reverse repurchase operation of 544.8 billion yuan at an interest rate of 1.40%, maintaining the previous rate, while a new tax policy on bond interest income will take effect from August 8, 2025, impacting the bond market significantly [1][3]. Group 1: Market Impact - The new tax policy will impose a value-added tax (VAT) on interest income from newly issued government bonds, local government bonds, and financial bonds, with a 6% rate for financial institutions and 3% for public funds [1][3]. - Existing bonds issued before August 8, 2025, will continue to enjoy tax exemption until maturity, creating a tax advantage for these bonds and potentially widening the yield spread between new and old bonds by 5-10 basis points [3][4]. - The credit bond market may benefit as the tax burden on interest income remains unchanged, leading to a potential narrowing of credit spreads compared to interest rate bonds [3]. Group 2: Fund Management Implications - Public funds may gain a relative advantage over proprietary accounts due to the new tax structure, as public funds will face a lower VAT rate on interest income compared to proprietary accounts [3][4]. - The scarcity premium of tax-exempt existing bonds is expected to be released quickly, while the attractiveness of these bonds may lead to a decrease in their yields [4][5]. - New bonds may need to increase their coupon rates to compensate for the tax burden, with estimates suggesting a rise of approximately 10-11 basis points for 10-year government bonds to maintain net interest income parity with existing bonds [5].

1. Report Industry Investment Rating There is no information provided regarding the industry investment rating in the report. 2. Core Viewpoints of the Report - The bond market showed a situation of "all negative factors priced in" this week. After the high - level oscillation in the first half of the week, influenced by factors such as the extension of Sino - US tariff exemptions, lack of unexpected policies in the Politburo meeting in July, significant corrections in the equity market and commodity prices, and poor July manufacturing PMI data, the 10 - year Treasury bond yield returned to around 1.7%. The news of resuming the collection of VAT on the interest income of some bonds on Friday afternoon pushed the 10 - year Treasury bond yield below 1.7% [2][6]. - The tax system for bond investment in China varies according to different bond types, investors, and income sources. The new tax policy exempts the old bonds of Treasury bonds, local government bonds, and financial bonds from VAT on interest income, while new bonds require banks and other institutional investors to pay 6.34% VAT and asset management products to pay 3.26% VAT [2][6]. - After the tax rate adjustment, institutions may prefer to hold old bonds. The new bond issuance may need to provide sufficient interest compensation. The actual yield of old bonds may be between 1.65% - 1.7%, and the new - old bond spread may be between 5 - 10BP [2][13]. - The central bank may support the policy adjustment to increase the nominal level of domestic bond interest rates and reduce the investment and trading willingness of financial institutions. The finance department may aim to expand the tax source. The policy may increase the annual VAT revenue by up to 140 billion, and the annual fiscal interest payment may increase by about 50 billion [2][3]. - In the short term, the bond market may maintain a volatile pattern. After the new tax policy, there may be a short - term trading opportunity for old bonds, but the market may still face disturbances, and the volatile pattern is difficult to break [2][23]. 3. Summary According to Related Catalogs 3.1 China's Bond Investment Tax System Varies by Bond Type, Investor, and Income Source - **VAT**: Interest income from Treasury bonds, local government bonds, financial bonds, and inter - bank certificates of deposit is exempt from VAT. For other bond types, the actual VAT rate for general legal entities is 6.34%, and for asset management products, it is 3.26%. Capital gains from most bonds are subject to VAT, but public funds are exempt. The actual VAT rate takes into account price - exclusive factors and additional taxes [2][6][7]. - **Income Tax**: Financial institutions' interest income from investing in Treasury bonds and local government bonds is exempt from income tax. Interest income from railway bonds is taxed at a reduced rate of 12.5%. Other bond interest income and capital gains are taxed at 25%. Contractual asset management products are not income tax payers, and the tax is borne by product holders. Personal investment in asset management products is currently tax - free, while enterprises and financial institutions are taxable. Public fund dividends are exempt from income tax [2][8]. - **Impact on Yield Difference**: Tax system differences are an important reason for the yield differences among different bond types in China. For example, the implied tax rate between Treasury bonds and policy - financial bonds has an upper limit of 25% [9]. 3.2 Under the New Tax Policy, the Market's Rush for Old Bonds is Mainly Due to Different Tax Rates Among Institutions - **New Tax Policy**: Starting from August 8, 2025, new - issued Treasury bonds, local government bonds, and financial bonds' interest income will be subject to VAT, while old bonds' interest income remains tax - free [11]. - **Pricing of New and Old Bonds**: Assuming the fair - value yield of 10 - year Treasury bonds is 1.7%, new bonds need to provide sufficient interest compensation. For asset management products, the new bond issuance rate only needs to reach 1.755% to be equivalent to old bonds, while for self - operated accounts, it needs to reach 1.808%. The actual new - old bond spread may be between 5 - 10BP [12][13]. - **Actual Situation**: Banks can invest in asset management products to avoid tax impacts, which may narrow the new - old bond spread. For short - duration bonds, the new bond yield may rise more. The demand for non - tax - adjusted bonds such as inter - bank certificates of deposit and credit bonds may increase, but the positive impact is limited [14]. 3.3 The New Tax Policy Can Increase the Nominal Interest Rate of New Bonds, but Commercial Banks May Bear Higher Tax Costs - **Policy Motivation**: The central bank may support the policy to increase the nominal level of domestic bond interest rates, and the finance department aims to expand the tax source [17]. - **Fiscal Revenue and Expenditure**: In the first year of the policy implementation, the additional VAT revenue may be less than 36 billion. Eventually, the annual fiscal VAT revenue increase may be within 140 billion, and the annual fiscal interest payment may increase by about 50 billion. The difference reflects the tax cost borne by banks and other financial institutions [3][19][21]. - **Future Policy Expectation**: There may be further adjustments to the tax system of asset management products, especially the tax - exemption policy for public fund dividends [22]. 3.4 After Repricing the Existing Bonds, the Bond Market May Still Show a Volatile Pattern - **Short - Term Market Trend**: The bond market may maintain a volatile pattern in the short term due to the lack of incremental policies in the Politburo meeting in July, limited inflation - driving ability of production - restriction policies, and the expected maintenance of a loose monetary policy [23]. - **Impact of New Tax Policy**: After the new tax policy, there may be a short - term trading opportunity for old bonds as their yields may decline by 0 - 5BP. However, the market may still face disturbances such as rising bank financing costs and potential tax policy adjustments for public funds, and the volatile pattern is difficult to break [24]. - **Long - Term Outlook**: A further decline in interest rates may require weaker fundamental data to force a policy shift. There is a possibility that the economic growth rate may decline in the second half of the year, and if combined with central bank bond - buying or interest rate cuts, interest rates may reach new lows, which may occur in the second half of the third quarter [24].

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].
