“全球资产定价之锚”来到临界点! 若9月CPI超预期 “股债双牛”叙事将遭遇重击

Core Viewpoint - The upcoming U.S. CPI inflation data is critical, as a higher-than-expected reading could disrupt the prevailing market consensus on interest rate cuts and negatively impact the recent strong rebound in U.S. stock and bond markets since October [1][2][10]. Group 1: U.S. Treasury Market Dynamics - The 10-year U.S. Treasury yield fell below 4% for the first time in six months, reaching a low of 3.9%, indicating a significant rebound in Treasury prices despite the government shutdown delaying key economic data [1]. - The overall return of U.S. Treasuries in October is approximately 1.3%, potentially marking the best monthly performance since February, driven by safe-haven buying and expectations of Federal Reserve rate cuts [5]. - If the September CPI data exceeds expectations, it could lead to a sharp rise in Treasury yields, negatively affecting global stock and bond markets [3][10]. Group 2: Inflation Expectations and Market Reactions - Economists predict that the overall CPI for September will show a month-over-month increase of 0.4%, with core CPI expected to rise by 0.3%, both indicating a year-over-year growth of 3.1%, the highest since May 2024 [8]. - There is a prevailing concern that strong inflation data could undermine the market's confidence in further rate cuts, as indicated by various market strategists [10][11]. - The market is currently pricing in a high probability of a 25 basis point rate cut in December, but a significant rise in inflation could jeopardize these expectations [9]. Group 3: Impact on Equity Markets - The strong performance of major tech companies and the AI sector has driven a historic investment surge in U.S. equities, with indices like the S&P 500 and MSCI Global Index reaching new highs [4]. - The 10-year Treasury yield serves as a critical component in equity valuation models, and a sustained decline below 4% could support a continued bull market in stocks, particularly in technology [3][4]. - If inflation remains stubbornly high, it could lead to a reassessment of risk asset valuations, including tech stocks and cryptocurrencies, which are currently at historical highs [4][10].
