Japan's $70B Intervention and Rate Hike Fail to Sustain Yen

Japan deployed over $70 billion in currency intervention alongside a Bank of Japan rate hike, yet the yen has weakened back toward the critical 160 level against the dollar. Despite the combined fiscal and monetary effort, the measures failed to produce lasting yen strength. USD/JPY is the primary pair to watch, with 160 acting as a key intervention threshold. Traders should expect heightened volatility and potential sudden yen spikes if Japanese authorities re-enter the market to defend this level.
