1. Report's Industry Investment Rating No relevant information provided in the report. 2. Core Views of the Report - In 2026, with insurance companies' asset - liability management focusing more on "income coverage ratio", the investment side may show a pattern of "holding local government bonds as the bottom - position, a structural differentiation in the demand for treasury bonds, and a rebound in the willingness to allocate secondary and perpetual bonds". Insurance companies' choices of specific bond types may show structural differentiation [2][24]. - The Financial Regulatory总局 issued the "Measures for the Asset - Liability Management of Insurance Companies (Exposure Draft)" in December 2025, which reconstructs regulatory indicators and governance standards, shifting the regulatory logic from "score - oriented" to "threshold management" [4][10]. - In 2026, as the insurance industry accelerates the transformation to floating - income products such as dividend - paying insurance and the regulatory focus shifts to effective duration, the liability duration of insurance companies may decline structurally, and the pressure on asset - liability duration matching at the indicator level of life insurance companies may be further alleviated [4][18]. - Looking forward to the year - end market, abundant liquidity may maintain the short - end advantage, while the long - end needs to focus on whether the pricing is gradually dominated by allocation funds.

1. Report Industry Investment Rating - Not provided in the document 2. Core Viewpoints of the Report - Last week, the traditional "stock-bond seesaw" effect failed again, with both the stock and bond markets rising and falling together. Long-term interest rates fluctuated sharply between the "reality of loose money" and the "frustration of strong expectations," and the oversold of ultra-long-duration assets reflected the crowding of market funds and the fragility of market sentiment [3][91]. - In the last four trading weeks of the year, the fact that the "sales new rules" have not fully "landed" remains the main market concern, but the approaching important meetings have restored the "loose money" expectation. The focus of market gaming may still be the emotional fluctuations caused by marginal policy changes [3][92]. - The report maintains the judgment of a recovery market in December but expects the downward space of interest rates to be relatively limited. It is recommended to adopt a left-side layout configuration rhythm, prioritize switching positions to medium - and short - term treasury bonds and policy financial bonds, and pay attention to trading opportunities of secondary perpetual bonds of the same term. As the meeting window approaches, gradually increase the offensive nature of the portfolio, control the overall duration center of the portfolio within the medium - to long - term range of 5 - 7 years, and avoid high - congestion assets [3][92][93]. 3.

Report Industry Investment Rating No relevant content provided. Core Viewpoints - If the new public offering sales regulations are implemented as per the draft for soliciting opinions, the cost - effectiveness of using traditional bond funds as liquidity management tools for institutional investors, especially wealth management products and bank proprietary trading, will be significantly weakened. Bond ETFs, outside the scope of the new fee reform and with advantages such as good liquidity and low trading costs, may become high - quality alternative tools for institutional liquidity management. The "new regulations" may drive institutional funds to migrate to credit - bond ETFs, bringing expansion opportunities for such products [2][5]. - The bond ETF market's scale slightly increased last week, with the increment mainly coming from credit - bond ETFs. As interest rates rise to a high - value level and institutional funds gradually enter the market, the bond market is expected to stop falling and rebound, which may drive the recovery of the bond ETF market. Additionally, with the upcoming implementation of the new public offering sales regulations and the bond market entering a volatile period, the potential value of bond ETFs as liquidity management and tactical allocation tools is expected to be re - evaluated by the market [2][45]. Summary by Directory 1. Sales New Regulations Impact: Credit - Bond ETF Incremental Funds Calculation - **Potential Scale of Migratable Funds**: - Approximate the scale of short - term pure - bond and passive index - type bond funds as the scale of bond funds held by wealth management products and bank proprietary trading for liquidity management. The combined proportion of short - term pure - bond and passive index - type bond funds under the heavy - position caliber of wealth management products and the affiliated - party holding caliber of bank proprietary trading is 28.9% and 10.1% respectively [9]. - Determine the proportion of credit - type bond funds in the short - term pure - bond and passive index - type bond funds held by wealth management and bank proprietary trading. The proportion of credit - type bond funds in short - term pure - bond and passive index - type bond funds under the heavy - position caliber of wealth management and the affiliated - party caliber of bank proprietary trading is 62.8% and 16.8% respectively, accounting for 18.1% and 1.7% of the total bond - fund scale held by each [11]. - Calculate the full - scale bond - fund scale held by wealth management products and bank proprietary trading. The estimated bond - fund holding scale of wealth management products and bank proprietary trading is 8496 billion yuan and 6927.1 billion yuan respectively. Based on this, the potential scale of migratable funds in the bond - type fund positions of wealth management products and bank proprietary trading under the full - scale is 1540.1 billion yuan and 1181.5 billion yuan respectively [21][22]. - **Actual Migrated Funds Calculation**: - Follow the "duration matching" principle. Part of the funds in the (0, 1], (1, 2], (2, 3], and (3, 4] duration intervals of credit - type short - term pure - bond and passive index - type bond funds held by wealth management products and bank proprietary trading will be transferred to credit - bond ETF products with similar duration intervals after the new regulations are implemented. - Set three scenarios: optimistic, neutral, and pessimistic, corresponding to 10%, 20%, and 50% of the fund migration ratio respectively. The incremental funds obtained by credit - bond ETFs in the optimistic, neutral, and pessimistic scenarios are 234.0 billion yuan, 467.9 billion yuan, and 1169.9 billion yuan respectively, with year - on - year increases of 4.7%, 9.3%, and 23.3% [33]. - **Market Capacity**: Even in the pessimistic scenario with the highest migration ratio, the incremental funds in each duration interval only account for 2.2%, 0.9%, 1.1%, and 0.4% of the corresponding index capacity. Existing credit - bond ETFs can absorb the potential fund migration caused by the new regulations without substantial constraints [42]. 2.
