AI Rally Concentration Adds Hidden Risk to USD/JPY Carry Trade

Meta's best monthly performance in over a decade, fueled by enthusiasm around its AI assistant, underscores how concentrated the current equity rally has become. A small group of AI-driven mega-caps continues to carry index-level gains while the broader market lags significantly behind.

This concentration risk is directly relevant to USD/JPY, a pair long favored for carry trades funded in low-yielding yen and deployed into dollar assets. As long as AI-driven optimism supports risk appetite, the carry trade dynamic tends to favor a firmer dollar against the yen.

However, such narrow leadership is fragile. Any stumble in AI sentiment or a broader equity pullback could trigger rapid carry-trade unwinding, sending USD/JPY sharply lower as yen shorts are covered en masse.
