Nikkei Tumbles as Rate Fears Bite Japanese Equities

The Nikkei 225 index opened lower on Friday, shedding 381 points after its prior session's close. This move is relatively modest in percentage terms but significant given the index's recent rally towards fresh highs.

The Japanese equities market has become increasingly sensitive to any signals from the Bank of Japan regarding rate hikes. Rising 10-year yields, pushing toward 3%, are tightening the screws on this trade.

The Nikkei's extended rally was largely built on cheap money, and rising yields threaten the foundation of that argument. Investors are now watching whether this pullback holds as a one-session shakeout or a more sustained retreat.
