USD/JPY breaks 158.00 as yen slides despite risk-off sentiment

USD/JPY surged through the 158.00 barrier to reach 158.25, with the yen continuing its steep decline despite typically supportive risk-averse market conditions. The pair has gained 1.2% (190 pips) this week as Japan's currency ignores traditional safe-haven flows. The disconnect highlights structural yen weakness driven by the Bank of Japan's ultra-loose monetary policy stance versus aggressive Fed tightening expectations. Japanese officials have intensified verbal warnings about excessive yen weakness, but markets remain skeptical about actual intervention. Technical momentum remains strongly bullish, with RSI in overbought territory above 70. Next resistance lies at 158.50, then the critical 160.00 psychological level where intervention risks increase substantially. Support is seen at 157.20 (previous resistance). Traders should remain vigilant for sudden volatility spikes if Japanese authorities decide to intervene to defend the currency.
