Report Industry Investment Rating - Not provided in the given content Core Viewpoints - From August 11 - 15, 2025, the central bank's 7 - day reverse repurchase had a net capital withdrawal, and a 6 - month outright reverse repurchase operation of 50 billion yuan was conducted. The overall liquidity remained stable and loose during the week, with a marginal increase in funding rates on the 15th due to the tax period. The central bank's monetary policy implementation report re - mentioned "preventing capital idling", but it is expected not to cause a tightening of the liquidity. The government bond net payment scale increased, most inter - bank certificate of deposit (NCD) yields rose, and the average leverage ratio in the inter - bank bond market increased [2][8]. Summary by Related Catalogs 1. Funding Situation - **Open Market Operations**: From August 11 - 15, 2025, the central bank's 7 - day reverse repurchase had a net withdrawal of 41.49 billion yuan. From August 18 - 22, 71.18 billion yuan of 7 - day reverse repurchases and 22 billion yuan of treasury deposits will mature, and a 12 - billion - yuan treasury cash deposit operation will be carried out on August 18. After the central bank conducted a 70 - billion - yuan 3 - month outright reverse repurchase operation on August 8, it carried out another 50 - billion - yuan 6 - month outright reverse repurchase operation on August 15, with a total excess roll - over of 30 billion yuan in August [6]. - **Funding Rates**: From August 11 - 15, the average values of DR001 and R001 were 1.33% and 1.37% respectively, up 1.9 basis points from August 4 - 8; the average values of DR007 and R007 were 1.45% and 1.47% respectively, up 0.6 basis points and down 0.1 basis points from August 4 - 8. DR001 increased marginally to 1.40% on August 15 when entering the tax payment stage. After the tax period ends, the funding rates are expected to return to the stable and loose level in the first half of August [7]. - **Government Bond Net Payment**: From August 11 - 17, 2025, the government bond net payment scale was about 41.036 billion yuan, an increase of about 3.98 billion yuan compared with August 4 - 10. From August 18 - 24, the government bond net payment scale is expected to be 26.41 billion yuan [8]. 2. Inter - bank Certificates of Deposit - **Yields**: As of August 15, 2025, the yields of 1 - month and 3 - month NCDs were 1.4600% and 1.5250% respectively, up 1 basis point and down 1 basis point from August 8; the yield of 1 - year NCDs was 1.6400%, up 2 basis points from August 8 [9]. - **Net Financing**: From August 11 - 17, 2025, the net financing of NCDs was about - 131.1 billion yuan. From August 18 - 24, the maturity repayment volume of NCDs is expected to be 794.7 billion yuan, with the roll - over pressure decreasing compared with the previous week [9]. 3. Institutional Behavior - The average leverage ratio in the inter - bank bond market increased. From August 11 - 15, 2025, the average calculated leverage ratio in the inter - bank bond market was 107.83%, compared with 107.70% from August 4 - 8 [10].

Core Viewpoint - The article analyzes the changes in the pricing of the 10-year government bond yield based on the monetary policy interest rate transmission framework, indicating a trend of narrowing the spread between the 10-year government bond yield and the 7-day reverse repurchase rate due to persistent interest rate cut expectations and a compression of long-term bond term premiums [2][41]. Group 1: Long-term Trends - The long-term trend suggests that the spread between the 10-year government bond yield and the 7-day reverse repurchase rate is likely to narrow, primarily due to a "re-anchoring" of the 10-year bond yield and a systematic decline in long-term bond term premiums as economic uncertainty decreases [2][41]. - The narrowing of the spread is influenced by the ongoing expectations of interest rate cuts and a compression of long-term bond term premiums, as the domestic economy transitions to a high-quality development phase with reduced volatility [6][41]. Group 2: Short-term Dynamics - In the short term, the extent of the spread's increase depends on the upward elasticity of the fundamentals, with historical data indicating that a significant widening of the spread requires confirmation of a bottom in the fundamentals and a tightening of narrow liquidity [4][41]. - Current leading indicators in the domestic economy have shown signs of recovery, but their ability to drive economic and inflation growth remains uncertain, as social financing to GDP has rebounded primarily due to low inflation affecting nominal GDP [42][41]. Group 3: Market Expectations - The market's expectation of future interest rate cuts is reflected in the bond market, where the 1-year government bond yield has remained below the 7-day reverse repurchase rate since 2024, indicating a persistent expectation of rate cuts [32][41]. - The compression of term premiums is another underlying reason for the low spread between the 10-year government bond yield and the 7-day reverse repurchase rate, driven by a consensus among market participants regarding weak expectations for income, housing prices, and inflation [37][41]. Group 4: Future Projections - It is projected that the spread between the 10-year government bond yield and the 7-day reverse repurchase rate will not rise significantly in the next 2-3 quarters, with expectations of only a slight increase to 40-50 basis points, and if the 7-day reverse repurchase rate is cut by 10-15 basis points, the 10-year government bond yield may fluctuate between 1.65% and 1.8% [5][46].

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - From August 4 to August 8, 2025, the central bank conducted a net withdrawal of funds through 7 - day reverse repurchase operations and carried out 700 billion yuan of 3 - month outright reverse repurchase operations. After the cross - month period, the funding rate declined. From August 4 to August 10, the net payment scale of government bonds increased, the overall yield to maturity of inter - bank certificates of deposit (NCDs) decreased, and the average leverage ratio in the inter - bank bond market increased. From August 11 to August 17, the expected net payment of government bonds is 360.1 billion yuan, and the maturity scale of NCDs is about 907.1 billion yuan [2]. - The outright reverse repurchase operation has more flexible timing compared to the medium - term lending facility (MLF). The central bank's operations in different months are to address various pressures on the liquidity, such as large - scale NCD maturities, tax payment months, and new bond issuance policies. The 6 - month outright reverse repurchase in August may be operated in the middle of the month to assist in stabilizing the funding situation during the tax payment period [7]. - The funding situation eased at the beginning of the month. From August 4 to August 8, the average values of DR001 and R001 decreased by 5.6 and 8.7 basis points respectively compared to the period from July 28 to August 1. The average values of DR007 and R007 decreased by 8.2 and 11.4 basis points respectively. In the future, the funding situation is expected to remain stable and loose overall, but the central bank's goal of preventing "idle funds" may limit the significant decline of the funding rate center [8]. Summary by Relevant Catalogs Funding Situation - **Outright Reverse Repurchase and 7 - day Reverse Repurchase**: From August 4 to August 8, 2025, the central bank's 7 - day reverse repurchase had a net withdrawal of 53.65 billion yuan. On August 8, it carried out 70 billion yuan of 3 - month outright reverse repurchase operations. The net investment of 3 - month outright reverse repurchase was 30 billion yuan. The maturity scales of 3 - month and 6 - month outright reverse repurchases in August are 40 billion and 50 billion yuan respectively [6]. - **Funding Rate**: From August 4 to August 8, the average values of DR001 and R001 were 1.31% and 1.35% respectively, down 5.6 and 8.7 basis points from July 28 - August 1. The average values of DR007 and R007 were 1.45% and 1.47% respectively, down 8.2 and 11.4 basis points from July 28 - August 1 [8]. - **Government Bond Net Payment**: From August 4 to August 10, the net payment scale of government bonds was about 37.06 billion yuan, an increase of about 8.3 billion yuan compared to July 28 - August 3. From August 11 to August 17, the expected net payment of government bonds is 36.01 billion yuan [8]. Inter - bank Certificates of Deposit (NCDs) - **Yield to Maturity**: As of August 8, 2025, the yields to maturity of 1 - month, 3 - month, and 1 - year NCDs were 1.4490%, 1.5300%, and 1.6175% respectively, down 4, 1, and 2 basis points from August 1 [9]. - **Net Financing Amount**: From August 4 to August 10, the net financing amount of NCDs was about 17.76 billion yuan, compared with about 1 billion yuan from July 28 to August 3. From August 11 to August 17, the expected maturity repayment amount of NCDs is 907.1 billion yuan, and the pressure of maturity renewal has increased compared to the previous week [9]. Institutional Behavior - **Leverage Ratio in the Inter - bank Bond Market**: From August 4 to August 8, the average calculated leverage ratio in the inter - bank bond market was 107.96%, up from the average of 107.63% from July 28 to August 1. On August 8 and August 1, the calculated leverage ratios were about 108.07% and 108.10% respectively [10].

Core Viewpoint - The potential for a rate cut by the Federal Reserve in September could lead to a corresponding decrease in China's Loan Prime Rate (LPR) on September 22, which would further lower domestic mortgage rates [1]. Group 1: Federal Reserve and Economic Policy - Trump is dissatisfied with Fed Chair Powell's reluctance to cut rates quickly, which he believes is necessary to boost the economy ahead of the midterm elections [2]. - The independence of the Federal Reserve is traditionally upheld, making it unprecedented for a president to demand the removal of a Fed chair, which could undermine international confidence in dollar assets [3]. - The resignation of Fed Governor Kugler provides Trump an opportunity to nominate a new member, potentially influencing future monetary policy [5][9]. Group 2: Implications for Monetary Policy - Trump's ability to nominate a "shadow chair" allows him to exert influence over the Fed without direct confrontation with Powell [8]. - The upcoming decisions by Trump regarding the new Fed governor and the implications for U.S.-Russia relations could significantly impact global markets [13][14]. - Current employment data suggests a high probability of a rate cut in September, with discussions around whether it will be 25 or 50 basis points [18]. Group 3: China's Monetary Policy Outlook - The LPR is expected to decrease by 10 to 15 basis points in September, with further cuts anticipated by the end of the year, depending on the Fed's actions [23]. - The LPR has been on a downward trend, with only one cut of 10 basis points in May this year, indicating a cautious approach to monetary easing [21][23]. - By 2026, there is a potential for more significant cuts in China's LPR, as the Fed may implement aggressive rate reductions, allowing for greater flexibility in China's monetary policy [23].

Group 1: Market Liquidity - In July, the overnight funding rate rose significantly to 1.53% and then to 1.65% on July 24, raising concerns about liquidity[1] - The People's Bank of China (PBOC) injected a net amount of 601.8 billion yuan through 7-day reverse repos on July 25, indicating a supportive stance on liquidity[1] - By the end of July, the overnight funding rate decreased to 1.36%, with the balance of 7-day reverse repos significantly higher than seasonal levels[1] Group 2: Government Debt Supply - It is estimated that in August 2025, government debt issuance will be between 2.17 trillion and 2.39 trillion yuan, with net financing close to 1.17 trillion to 1.39 trillion yuan[5] - From January to July 2025, net financing from ordinary government bonds reached 2.56 trillion yuan, with various types of bonds contributing to a total of 9.02 trillion yuan utilized, accounting for 65% of the annual quota of 13.86 trillion yuan[5][27] - The issuance of local government bonds is progressing slightly faster than that of national bonds[5] Group 3: Interbank Certificates of Deposit - The 1-year interbank certificate of deposit (CD) rate rose slightly after reaching around 1.6% in early July, with the market beginning to see price increases[6] - The maturity scale of CDs in August increased to 3.07 trillion yuan, indicating heightened renewal pressure[6] - The 1-year CD rate is expected to fluctuate between 1.6% and 1.7%, with rates above 1.65% considered to have certain allocation value[6]

Group 1: Report Industry Investment Rating - Not provided in the content Group 2: Core View of the Report - The capital market in August does not have a basis for tightening. Although the bond market has become desensitized to capital and fundamental information recently, it will eventually return to these two concerns. Currently, the Sino - US tariff negotiations have not released more positive information, and the latest economic data does not support a shift in monetary policy [2][9] Group 3: Summary by Relevant Catalogs 1. Overall Judgment of August Capital Market - In July, after the capital interest rate dropped to nearly 1.3% at the beginning of the month, there were two significant increases. On July 25, the central bank immediately made a large - scale net investment of 601.8 billion yuan in 7 - day reverse repurchase to support the capital market, indicating that the central bank's attitude of supporting the capital market has not changed. The overnight capital interest rate has dropped to 1.36%, and the balance of 7 - day reverse repurchase is significantly higher than the seasonal level, similar to the situation in the second quarter [2][9] 2. Open Market - In August, the maturity of MLF is 300 billion yuan, and the maturity of outright reverse repurchase is 900 billion yuan, totaling 1.2 trillion yuan, less than the 1.5 trillion yuan in July. Since May, the combined caliber of these two tools has been net investment, so there is no need to worry too much. Starting from August, the maturity time and operation time of MLF will change from misaligned to consistent, solving the problem of affecting market expectations for medium - term liquidity [3][14] 3. Government Bond Supply - It is expected that in August 2025, the government bond issuance will be 2.17 - 2.39 trillion yuan, and the net financing will be 1.17 - 1.39 trillion yuan, close to the 1.25 trillion yuan in July. From January to July 2025, a total of 9.02 trillion yuan of the annual quota has been used, accounting for 65% of the annual 13.86 trillion yuan, with the local bond issuance progress slightly faster than that of national bonds. There are new policy tools to be launched, and they are expected to be implemented in the third quarter [4][17][18] 4. Inter - bank Certificates of Deposit - Recently, the increase in market risk appetite has not only pressured the bond market but also disturbed the inter - bank capital market. The 1 - year CD interest rate started to rise slightly after reaching around 1.6% at the beginning of July. The maturity scale of CDs in August will rise slightly to 3.07 trillion yuan, increasing the pressure on renewal. Before the policy interest rate is further lowered, the 1 - year CD interest rate is likely to fluctuate between 1.6% - 1.7%, and there is a certain allocation value at 1.65% and above. Unless the central bank tightens liquidity investment, the probability of a significant price increase for issuance is not high, and the CD interest rate in August will mainly fluctuate seasonally [5][25]

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - The current foundation of the bond bull market is difficult to reverse in the short - term. The impacts of anti - involution policies and the Yajiang Hydropower Project are long - term issues, and their short - term disturbances to the bond market are controllable [2]. - Even if supply - side reform 2.0 measures are introduced in the July Politburo meeting, it will take time for the policies to be implemented and for the PPI to turn positive, and the impact on the bond market reversal also needs time [2]. - There is still a probability of reserve requirement ratio cuts and interest rate cuts in the second half of 2025 [2]. - The yield of the 10 - year Treasury bond will return to the range of 1.65% - 1.70% after the short - term calm of long - term topics such as "anti - involution" and infrastructure [3]. 3. Summaries Based on Relevant Catalogs 3.1 Interest Rate Bonds Last Week Data Review - **Funding Rates**: From July 21 to 25, DR001 rose from 1.36% to 1.52%, a 16BP increase; R001 rose from 1.40% to 1.55%, a 15BP increase. DR007 rose 16BP from 1.49% to 1.65%, and FR007 rose 25BP from 1.50% to 1.75% [8]. - **Open Market Operations**: The central bank's reverse repurchase投放 reached 16563 billion yuan, with a large total maturity of 17268 billion yuan, resulting in a net capital withdrawal of 705 billion yuan [8]. - **Sino - US Market Interest Rate Comparison**: The inversion of the Sino - US bond yield spread widened. The US 6 - month SOFR rate fluctuated around 4.20%, while the Chinese 6 - month SHIBOR rate rose from 1.59% to 1.61%. As of July 25, the 6 - month interest rate spread was - 259BP. The 2 - year/10 - year Sino - US bond yield spreads were - 247BP and - 266BP respectively, with a slight narrowing of the long - and short - term spreads during the week [14]. - **Term Spreads**: For Chinese bonds, the 10 - 2 year spread widened from 29BP to 30BP. For US bonds, the 10 - 2 year spread narrowed from 53BP to 49BP [14]. - **Interest Rate Term Structure**: Both Chinese and US bond yields pulled back last week. The Chinese bond yield curve steepened, while the US bond yield curve flattened. The overall pull - back range of Chinese bond yields was about 4BP - 6BP, and the middle - term US bond yields pulled back by about 5BP [15]. - **Industrial and Fiscal Data**: In June 2025, the total profit of industrial enterprises above the designated size decreased by 4.3% year - on - year, with a narrowing decline. The general public budget revenue decreased by 0.31% year - on - year, with tax revenue recovering and non - tax revenue declining [19]. 3.2 Key Bond Market Events Last Week - **LPR Remained Unchanged**: On July 21, the 1 - year LPR was reported at 3.0% and the 5 - year LPR was reported at 3.5%, both remaining unchanged from the previous month [24]. - **Bond Market Adjustment**: Last week, due to anti - involution policy expectations and the Yajiang Hydropower Station theme, the bond market significantly adjusted. The 10 - year Treasury bond yield once pulled back to around 1.75%, and the 30 - year Treasury bond pulled back to around 1.97% [20]. - **Exchange Measures and Central Bank Operations**: The Guangzhou Futures Exchange and the Dalian Commodity Exchange issued notices to adjust trading limits, resulting in a more than 20% decline in trading volume. The central bank conducted a 4000 - billion - yuan MLF operation on July 25 and a 4958 - billion - yuan 7 - day reverse repurchase operation on July 28 [1][20].

Group 1 - The central bank conducted a 7-day reverse repurchase operation amounting to 495.8 billion yuan, with the same amount being bid and awarded [1] - The operation interest rate remains unchanged at 1.40%, consistent with previous rates [1]
