垃圾债市场闪烁黄灯，这些警示信号需警惕
Junk bonds are 'flashing yellow.' Watch these warning signs
高收益债市场出现裂缝，收益率从一个月前的7.22%升至8.1%，整体息差达315个基点，但专家称其只是“闪烁黄灯”、远未到红色。压力主要集中在CCC及以下最低评级债券，息差过去一年大幅升至约1250个基点，而BB级息差为194个基点；受访策略师称利差扩大仍属有序，并建议在高收益债中精选单B级机会。
High-yield bond stratification data provides a window to observe the transmission of credit risk: the spread of CCC grade has risen to about 1,250 basis points while the BB grade is still relatively mild, indicating that the pressure is currently concentrated on the lowest rating and the risk has not yet been systemized. For gold and foreign exchange markets, such signals mean that risk aversion may increase but to a controllable extent. Traders should pay attention to whether credit spreads spread to high ratings and the potential disruption to global liquidity expectations.
