Japanese Bonds Recover Slightly After Record Slump Amid Inflation Concerns

Japanese government bonds showed tentative signs of recovery following a historic selloff, as unrealized losses surged across long-dated maturities. The rebound interrupted five consecutive days of declines fueled by mounting inflation pressures and deteriorating investor sentiment.

Core consumer prices jumped 3.5% year-over-year in April—the steepest increase in more than two years—forcing markets to recalibrate expectations for Bank of Japan policy tightening. The 30-year JGB yield briefly touched a record 3.185% before retreating to 3.115% by week’s end.

Ultra-long duration bonds bore the brunt of the selloff as traders reacted to proposed consumption tax cuts. Market participants viewed the fiscal stimulus measures as particularly reckless given Japan’s escalating public debt burden, triggering a flight from 20-, 30-, and 40-year securities.
