Japan's Nikkei 225 index extended its decline on Wednesday, dropping to its lowest level since August 10 as a surge in long-term government bond yields rattled equity markets. The benchmark traded at 65,684 points, down from this week's high of 69,622, as investors weighed the prospect of more aggressive monetary tightening by the Bank of Japan (BoJ) and renewed geopolitical risks in the Middle East.
Bond yields soar on BoJ expectations
The 30-year Japanese government bond yield jumped to 4.11%, its highest level since May 20, while the five-year yield climbed to 2.13%. This move mirrors a global trend, with U.S. 30-year Treasury yields reaching a 20-year high and German five-year yields rising to 3.79% from pandemic-era lows. The sharp repricing in bond markets reflects growing concerns about inflation and central bank policy.
Analysts at Mizuho said on Tuesday that they expect the BoJ to hike interest rates sooner and more frequently than previously anticipated. The bank's decision is likely driven by rising inflationary pressures, partly stemming from higher energy costs. Crude oil prices have surged, with Brent trading at $91.8 and West Texas Intermediate (WTI) at $85, as the possibility of a resumption of U.S.-Iran hostilities grows. Both sides have not agreed to a ceasefire, and Iran believes it holds an advantage, raising the odds of further conflict.
Yen weakness adds to pressure
The Japanese yen remains under pressure, with the USD/JPY pair trading at 159.36 on Wednesday, up sharply from this month's low of 155.23. This suggests that earlier interventions by Japanese authorities have had limited effect. Analysts believe the yen will stay weak until the BoJ raises rates further to narrow the interest rate differential with the U.S. A weaker yen typically boosts exporter stocks, but the current environment of rising yields and global risk aversion has weighed on the broader market.
Tech and financial stocks lead declines
Most Nikkei 225 constituents traded lower, with technology names suffering the steepest losses. Softbank, Kioxia, and Tokyo Electron fell 7.48%, 8.38%, and 2.16%, respectively. Major financial and industrial firms also declined, with Mitsubishi UFJ, Toyota, and Hitachi all dropping more than 4%. The selloff was broad-based, reflecting investor anxiety over higher borrowing costs and potential economic slowdown.
Technical outlook turns bearish
From a technical perspective, the Nikkei 225 has broken below its 50-day exponential moving average (EMA) and the top of the Murrey Math Lines trading range. The Relative Strength Index (RSI) has also turned downward, signaling weakening momentum. The next key support level to watch is the Major S/R pivot point at 62,500. If the index fails to hold above this level, further downside could follow.
The current market environment is reminiscent of recent episodes where rising yields have pressured equities globally. For instance, U.S. stocks also slipped as Treasury yields climbed, and chip stocks like Micron dropped sharply under similar conditions. The Nikkei's slide is part of a broader trend of risk-off sentiment driven by bond market dynamics.
Investors will be closely watching the BoJ's next policy meeting for signals on the pace of rate hikes. Meanwhile, developments in the Middle East and oil prices will remain key drivers of market sentiment. The combination of rising yields, a weak yen, and geopolitical uncertainty suggests that volatility in Japanese equities could persist in the near term.
