Group 1: Bond and Bill Market Analysis - Since July 22, there has been a notable divergence between medium to long-term bond yields and short-term bill rates, with the 10Y government bond yield at 1.72%, up 4 basis points from July 21, while the 3M bill discount rate fell to 0.50%, down 71 basis points [3]. - Bill market rates exhibit both funding and credit attributes; recent declines in bill rates suggest a stronger influence from credit attributes, as evidenced by the slight increase in DR007 to 1.52%, up 3 basis points from July 21 [3][4]. - The volatility of bill market rates tends to be greater in the latter part of the month, indicating banks' adjustments in credit supply, which may reflect increased credit issuance in the latter half of the month [4]. Group 2: Economic Implications and Future Outlook - Investors are currently trading on the "anti-involution" narrative and its impact on commodity prices, which may affect the attractiveness of bond assets [4][5]. - The sustainability of the "anti-involution" logic depends on the breadth of rising commodity prices and their impact on real economic growth, with a stronger influence on PPI growth compared to CPI growth [4]. - In the medium term (one to two quarters), the probability of bond yield declines is greater than increases, given ongoing economic challenges and the need to lower overall financing costs [5]. - In the short term (one to two weeks), bond yields are expected to decline, as the market has passed the peak pressure of the current adjustment phase [5].
