Japan’s yen drifts back to intervention levels as markets test Tokyo’s resolve

Yen back in danger zone as Tokyo officials keep investors on edge

Japan spent ~$63 billion in suspected yen-buying intervention in late April and early May, pushing USD/JPY back toward 159.65 — near the threshold that triggered action a month ago. With the BOJ maintaining a cautious rate stance and ~$1 trillion in reserves theoretically available but politically and diplomatically constrained, the yen-dollar rate remains a live risk for any CFO or treasury team with JPY exposure or Japan-based operations.
