In October 2026, a notable shift occurred in the correlation between oil prices and treasury yields, which had previously maintained an 80% correlation throughout the year. Jeffrey Rosenberg, a senior portfolio manager at BlackRock, emphasized that this breakdown indicates a market perception where geopolitical risks are now secondary to concerns surrounding the AI sector.
The recent volatility in the AI trade, exemplified by significant declines in tech stocks like Google, has led to a reassessment of economic growth expectations, with bond yields decreasing as investors anticipate a broader economic slowdown linked to AI performance.
Rosenberg pointed out that the third-quarter GDP growth was heavily driven by AI-related investments, with business investment rising 12.7%, marking the largest increase outside the pandemic since 2011. Despite this, he cautioned that the persistent inflation and rising oil prices pose ongoing challenges for fixed-income assets, complicating their role as a hedge against stock market fluctuations.
The anticipated influx of AI-related debt into public bond markets could lead to lower prices and higher spreads, although the transparency of these markets may provide new trading opportunities. Overall, investors are advised to remain cautious, weighing the potential benefits of bonds against the risks associated with the evolving AI landscape
