被忽视的风险：日本长端收益率失控，会否触发美股“10月式暴跌”？

Core Viewpoint - Japan's long-term government bond yields are experiencing a significant and uncontrolled rise, with the 10-year yield approaching the critical 2% level and the 30-year yield soaring to 3.43%, indicating potential global market risks [1][4]. Group 1: Yield Trends - The 10-year government bond yield in Japan has been consistently reaching new highs, driven by a "magnet effect" around the 2% mark, with technical indicators suggesting a strong upward trend [2]. - The 30-year bond yield has shown even stronger performance, breaking through the 3.3% level and indicating substantial upward potential due to a lack of resistance above [4][6]. Group 2: Historical Context - Analysts recall the significant market drop in late October last year when Japanese rates began to rise, which coincided with a sharp decline in the Nasdaq 100 index, highlighting a historical correlation between Japanese rates and U.S. equity performance [5][8]. Group 3: Market Volatility - The current rise in Japanese bond yields is characterized by a clear trend, breaking through technical resistance levels and indicating strong upward momentum [6]. - Despite most traders not including Japanese rate changes in their daily risk assessments, this macro-level shift could significantly increase market volatility [9][11]. Group 4: Global Impact - The widening yield spread between Japanese and U.S. 10-year bonds is reshaping global capital allocation, reflecting deepening monetary policy divergence and potentially triggering large-scale cross-border capital flows [12]. - The increase in the yield spread may lead to adjustments in arbitrage trading, particularly affecting yen carry trades, which could have significant implications for global risk asset prices [12]. Group 5: Safe-Haven Assets - The gold market has begun to react to the rise in Japanese long-term yields, indicating that gold prices are sensitive to changes in Japanese government bonds and reflecting growing market concerns about potential risks [14][15]. - The movement in gold prices, whether measured in yen or dollars, signals an increase in demand for safe-haven assets, often foreshadowing broader market adjustments [15][17].
