#1 · Yen intervention aftermath tightens global funding conditions
Impact 8/10
What — US–Japan joint intervention has already yanked USD/JPY off extremes. The risk is not the headline intervention itself; it is the knock-on effect on carry, leverage, and cross-asset positioning if USD/JPY keeps moving lower and funding trades continue to unwind.
Takeaway — This is the cleanest live macro risk. It can hit equities through de-grossing, not through Japan alone. Biggest sensitivity is high-duration US tech and crowded carry-funded risk.
