The Australian dollar extended its decline against the Japanese yen on Wednesday, with the AUD/JPY pair sliding below the 112.00 handle as speculation over potential intervention by Japanese authorities continued to shape market sentiment. The break below this psychological level, combined with a decisive move under the 100-day simple moving average (SMA), has tilted the technical bias firmly to the downside.
According to MUFG Bank, the threat of official action from Tokyo is also capping yen weakness against the US dollar, acting as a credible deterrent for traders looking to push the pair aggressively higher. While fundamentals—including a wide interest rate differential between the Federal Reserve and the Bank of Japan—favour further yen depreciation, the persistent intervention risk keeps a floor under the Japanese currency. Officials have reiterated their readiness to step in against excessive volatility, and the 150–152 zone in USD/JPY remains a particularly sensitive threshold.
For AUD/JPY, the technical picture has deteriorated further. The pair has now posted three consecutive daily declines and closed below the 100-day SMA around 112.30—a moving average that had provided dynamic support during the late‑2024 rally. Momentum indicators such as the relative strength index (RSI) are pointing lower but have not yet reached oversold territory, suggesting that there is still room for additional selling. The next key support sits at the 200-day SMA near 110.80, followed by the 110.00 round number. Resistance is now seen at the broken 100‑day SMA and then the 113.00 zone.
Market participants are closely monitoring any fresh verbal warnings or actual intervention from Japan’s Ministry of Finance and the Bank of Japan. A sudden yen strengthening triggered by intervention could spark a broader unwinding of carry trades, potentially rippling into risk assets, including cryptocurrencies. Until a clear catalyst—such as a shift in Bank of Japan policy or a notable improvement in risk appetite—emerges, the path of least resistance for yen crosses appears to remain lower.
