Core View of the Report Since 2024, the bond trading attributes of joint-stock banks, which were "neglected" in traditional institutional behavior research, have expanded, and high-frequency operations of interest rate bands can be observed. Based on their behavior, corresponding buy and sell timing signals can be constructed, and the follow-up strategy outperforms the benchmark return (10Y Treasury bond) by about 30% [2][4]. Summary by Relevant Catalog 1. Why Do We Focus on the Trading Behavior of Joint-Stock Banks? 1.1 A Consensus on the Institutional Behavior of Joint-Stock Banks in the Market Joint-stock banks are the last "puzzle piece" in institutional behavior research. The market consensus on the institutional behavior of joint-stock banks is that they usually conduct distribution in the secondary market. Joint-stock banks and city commercial banks typically have an obvious nature of "primary subscription and secondary distribution," so they generally show a net selling feature in secondary cash bond transactions. Historically, joint-stock banks have shown a net selling state in nearly 90% of the time, similar to city commercial banks [11]. 1.2 New Features of the Institutional Behavior of Joint-Stock Banks Since 2024 Since 2024, joint-stock banks have started to increase interest rate band trading. On the one hand, as the Ministry of Finance has increased the issuance scale of single Treasury bonds, the stock scale of active bonds with key tenors (such as 10Y) has reached a new high, reducing the impact of distribution from new bond issuance. On the other hand, since 2024, the overall liability side of the banking system has been squeezed, making them more reliant on the income from bond investment business on the asset side. Therefore, the trading volume of joint-stock banks for old 10-year Treasury bonds has increased significantly, and they are no longer in the previous mode of distribution and passive buying during bond market corrections [2][14]. 2. Judgment of Interest Rate Timing Signals Based on the Trading Behavior of Joint-Stock Banks 2.1 Construction of Low-Frequency Interest Rate Timing Signals Based on the trading behavior of joint-stock banks, a cash bond follow-up strategy signal is constructed. By studying the trading behavior of joint-stock banks on long-term bonds and eliminating the impact of the latest bond distribution, in the past year, the long-term interest rate band trading return following joint-stock banks under the 10MA caliber has exceeded the benchmark by nearly 30%. From September last year to late June this year, the 10-year Treasury bond yield declined by 49bp, while the interest rate band return following joint-stock banks was 62bp, with an excess return of 13bp over the benchmark and an overall excess return rate of 26%. Moreover, if the continuous days of the signal triggered by joint-stock banks exceed 5 trading days, the winning rate of their buying signals in the past year was 100%, capturing a total band of 59bp, and the winning rate of selling signals was 60%, avoiding a capital loss of 15bp [2][18][21]. 2.2 Construction of Medium-Frequency and Other Timing Signals Two other perspectives can be used to observe the interest rate timing signals of the trading behavior of joint-stock banks. First, observe the higher-frequency 5MA caliber buying signals. Since 2025 is a year of strong fiscal efforts, there may still be distribution impacts under the old bond caliber at some time points, so the buying signals of joint-stock banks may be more meaningful than the selling signals. Second, observe the extreme value of single-day demand. If it exceeds a certain threshold, it can be regarded as an overbought or oversold signal, and the historical backtesting shows a relatively high winning rate [3][24][27].

Economic Indicators - In June, the official manufacturing PMI recorded 49.7%, a slight increase from 49.5% in May, but still below the expansion threshold[2] - The non-manufacturing PMI rose to 50.5% from 50.3%, indicating continued expansion in the service sector[2] - The composite PMI output index increased to 50.7%, reflecting overall economic recovery[2] Manufacturing Sector Insights - The production index continued to expand, with new orders rising above the threshold, indicating improved demand[3] - New export orders showed a minor recovery, with domestic orders performing better than foreign ones[3] - The purchasing volume surged into the expansion zone, reflecting a positive shift in corporate procurement attitudes[3] Price and Inventory Dynamics - Both factory prices and major raw material purchase prices increased, indicating a balance between downstream demand recovery and upstream commodity price fluctuations[3] - Finished goods inventory rose significantly, while raw material inventory continued to recover, suggesting a cautious approach to inventory management[3] Sectoral Performance - The equipment manufacturing PMI increased by 0.2 percentage points to 51.4%, while the consumer goods sector PMI rose to 50.4%, marking six consecutive months of growth[4] - Large enterprises maintained strong PMI performance, while small enterprises saw a decline of 2 percentage points, highlighting resource imbalances within the industry[4] Future Outlook - The EPMI index fell to 47.9%, down 2.1 percentage points from the previous month, indicating a divergence from the PMI due to ongoing trade tensions and tariff issues[10] - Economic recovery remains uncertain, with the real estate sector still in a downturn and consumer prices under pressure, suggesting reliance on fiscal stimulus for demand recovery[13] - The bond market is expected to remain stable, supported by the current economic data and policy expectations, despite external uncertainties[16]

Group 1: Core Views - The report mainly discusses three questions in light of the Q3 national debt issuance plan announced on June 30: whether the ultra-long bonds will experience a bond-switching market again, what rules can be grasped if the bond-switching market arrives, and how to view the supply pressure of interest rate bonds within the year [2] - The issuance scale of ultra-long special national debts this year has increased and remained constant, with 20Y/30Y/50Y at 50 billion yuan, 71 billion yuan, and 50 billion yuan respectively. The estimated total issuance for the year is about 1.302 trillion yuan, roughly in line with the 1.3 trillion yuan announced during the Two Sessions [3] - The 20Y bonds may experience a bond switch, while the 30Y active bond is likely to remain 2500002.IB. The short-term probability of a 30Y bond switch is low [4] - For 20Y national debts, if the single-bond issuance scale exceeds 5 billion yuan, the new bond may see a rush, with interest rates declining first, and the current active bond 2500001.IB may adjust. For 30Y national debts, if there is an expectation of an active bond switch, the single-bond issuance scale on July 14 needs to be large enough, or the issuance scale of each period of the bond needs to be small enough [6] - The supply peak of interest rate bonds may occur in August, and the supply pressure in July is significantly reduced. The bond market in July is favorable from the supply perspective. The central bank may restart national debt purchases in August to hedge against the supply peak or announce it in advance in July [6] Group 2: Report Industry Investment Rating - There is no relevant content provided in the text Group 3: Summary by Related Catalogs Perspective 1: Is it possible for ultra-long bonds to be switched? - The issuance scale of ultra-long special national debts this year has increased and remained constant, different from the past where the single-bond issuance scale was usually small and the reissuance scale occasionally changed [3] - Based on the linear extrapolation of the special national debt issuance scale from the beginning of the year to date, the total issuance for the year is about 1.302 trillion yuan, consistent with the announced amount [3] - The 20Y bonds may experience a bond switch, and if the first issuance scale of 20Y bonds exceeds 5 billion yuan, the market may expect this bond type to become the active bond. The short-term probability of a 30Y bond switch is low, and the active bond 2500002.IB position can be maintained [4] Perspective 2: How to respond if there is an expectation of an active bond switch? - For 20Y national debts, if the single-bond issuance scale exceeds 5 billion yuan, the new bond may see a rush, and the current active bond 2500001.IB may adjust [6] - For 30Y national debts, if the single-bond issuance scale on July 14 exceeds 12 billion yuan, investors may expect the final scale of this 30Y national debt to exceed the current active bond, leading to a rush. If the issuance scale of the 30Y special national debts on July 14, July 24, and August 8 is small enough, the expectation of an active bond switch may increase [6][7] - The supply peak of interest rate bonds may be in August, and the supply pressure in July is reduced. The bond market in July is favorable from the supply perspective. The strategy can maintain the duration and wait for the opportunity of interest rate decline in the second half of the year [6]

Report Industry Investment Rating No relevant content provided. Core Views of the Report - **Hua'an's View**: It is recommended to switch to active bonds to capture the left - hand side of the bond market trend. The trading mainline of the bond market is unclear. Although the overall situation is favorable, there are still negative factors under the high - duration and high - leverage of investors. The fundamentals are not likely to be negative for the bond market, and the central bank has an obvious intention to support the capital market. Holding 10Y/30Y active bonds helps to obtain capital gains when positive factors materialize and stop losses in case of negative factors [2]. - **Seller's View**: The sentiment index has slightly declined, but more than 60% of fixed - income sellers are bullish on the bond market. Among 29 institutions, 19 are bullish, 8 are neutral, and 2 are bearish [2]. - **Buyer's View**: The overall view of fixed - income buyers is still bullish on the bond market, but the sentiment index has declined for two consecutive weeks. Among 24 institutions, 10 are bullish, 13 are neutral, and 1 is bearish [3]. Summary by Relevant Catalogs 1. Seller and Buyer Markets 1.1 Seller Market Sentiment Index and Interest - rate Bonds - The weighted sentiment index this week is 0.48, and the unweighted index is 0.60, down 0.07 from last week. 66% of institutions are bullish, believing that July is an important window for long - positions due to historical patterns, economic weakness, and loose funds, with low bond supply pressure and favorable quarter - end institutional behavior. 27% are neutral, citing limited positive impact of the Lujiazui Forum on further decline of capital interest rates, economic resilience in the context of export rush, and potential unexpected outcomes from Sino - US talks. 7% are bearish, concerned about the stock market driving up bond interest rates and mean - reversion of interest rates [10]. 1.2 Buyer Market Sentiment Index and Interest - rate Bonds - The buyer sentiment index this week is 0.23, unchanged from last week. 42% of institutions are bullish, expecting loose funds and a possible quarter - on - quarter weakening of the economic fundamentals in Q3. 56% are neutral, as the Q2 monetary policy meeting has reduced expectations of broad credit, and the equity market suppresses bond market sentiment. 2% are bearish due to low yields [11][12]. 1.3 Credit Bonds - Market hot - topics include seasonal entry of wealth management funds and expansion of credit ETFs. Seasonal entry of wealth management funds may cause short - term disturbances to the credit market as wealth management scale expands after the quarter - end and institutional allocation power strengthens. The market for credit ETF component bonds is expected to continue [18]. 1.4 Convertible Bonds - Institutions generally hold a neutral - to - bullish view this week. 38% are bullish, noting the relative strength of debt - biased convertible bonds and the catch - up of bottom - position varieties. 62% are neutral, expecting the equity market to strengthen, limited incremental information from the Politburo meeting, and suggesting attention to the central price of convertible bonds [20]. 2.

Report Industry Investment Rating No relevant content provided. Core Views of the Report - The game space for the bond market from the economic fundamentals is shrinking. The economy performed well in Q1, and it is likely to be decent in Q2. It is highly probable that the annual growth rate will reach around 5%. Considering the bond market's front - running effect, not adding positions now may lead to missing an important long - buying window this year. For public funds with relative ranking assessments, it will be extremely difficult to outperform peer products in the second half of the year [4][10]. - Whether the central bank will restart bond purchases is a significant game point in the current bond market. Currently, market sentiment has reached a high level, with the bond market's leverage ratio and bond fund duration both rising. If the central bank announces bond purchases at the end of the month, the short - end yields may decline further, driving down the long - end yields. However, the monetary authority may be aware of the bond market's front - running tendency, and considering that the June 18th Lujiazui Forum did not mention restarting bond purchases and the central bank's Q2 monetary policy meeting maintained the statement of "monitoring changes in long - term bond yields", caution should be exercised regarding the central bank's potential restart of bond purchases [4][10]. - Investors face a prisoner's dilemma when gambling on the central bank's bond - buying. If the central bank restarts bond purchases, investors who miss the opportunity may find it difficult to have another chance to boost returns this year. For those who add positions, the ranking competition depends on the depth of strategy implementation (leverage, duration). If the central bank does not announce bond purchases, heavy - position investors may incur losses, and the ranking competition among those who added positions depends on the speed of stop - loss [4][10]. Summary by Directory 1. This Week's Institutional Behavior Review - **Overall Situation**: At the cross - quarter time point, the bond market was volatile, with short - end bonds performing better. The 10 - year treasury bond yield remained flat, while the 1 - year and 3 - year yields decreased slightly by 1 - 2bp. Investors face a prisoner's dilemma due to factors such as cross - quarter, public funds' pursuit of rankings and scale, the uncertainty of central bank bond - buying, and the yet - to - be - released June PMI data. Large banks have been buying short - term bonds for nearly a month, non - bank institutions have high chasing sentiment, and other product - type net purchases have increased significantly [2][9]. - **Yield Curve**: Treasury bond yields declined at the short - end and rose at the long - end. The 1Y yield decreased by 1bp, 3Y by 1bp, while 5Y, 7Y, 10Y, 15Y, and 30Y yields rose by about 1bp, 3bp, 1bp, 1bp, and 1bp respectively.

The main fund - borrowing party was funds, and the money - market fund outflows first increased and then decreased [27]. 3. Duration of Medium - and Long - Term Bond Funds - **Median Duration**: This week (June 23rd - June 27th), the median duration of medium - and long - term bond funds was 2.87 years (de - leveraged) and 3.17 years (leveraged).
