Japan’s potential currency intervention keeps AUD/JPY retreating, trading near 109.70 and remaining below 110.00

    AUD/JPY eased after the prior session’s rise and traded near 109.70 in Asian hours on Monday. The Yen strengthened after Bank of Japan Governor Kazuo Ueda said authorities may act against excessive one-way currency moves. Ueda said exchange-rate moves affect Japan’s economy and inflation, and that the Bank will monitor trends. He added policy could be adjusted depending on effects on growth, the price outlook and risks.

    Bank Of Japan Signals

    Monday’s Summary of Opinions from the March policy meeting said several policymakers still see scope for further monetary tightening soon. One member said rate rises would be appropriate if economic and price forecasts are met, while another linked future timing to developments in the Middle East, wages, inflation and financial conditions. The Australian Dollar stayed under pressure as energy prices rose on supply concerns and reduced expectations of a quick end to the Iran conflict. Iran-backed Houthi forces in Yemen carried out their first strikes on Israel over the weekend and said attacks would continue until operations against Iran and its allies stop. The Houthis also threatened Red Sea shipping and Saudi energy infrastructure, adding to supply risks. Reports said the United States is preparing for an extended ground campaign in Iran and is deploying thousands of troops to the region. Australia’s Prime Minister Anthony Albanese said the National Cabinet approved a National Fuel Security Plan. Fuel excise on petrol and diesel will be halved for three months, and the heavy vehicle road user charge will be temporarily removed.

    Recent Price Action Context

    We are currently seeing AUD/JPY trade with significant volatility around the 104.50 level. This is a noticeable shift from this time last year, when the cross was pushing towards 110.00 before Bank of Japan commentary caused it to retreat. The market has since priced in a more assertive BoJ, making sustained Yen weakness less certain. Looking back, the warnings from BoJ officials in 2025 about further tightening were a clear signal of the policy shift that followed. We have since seen the BoJ make a historic move away from negative rates, with their policy rate now standing at 0.1%, and officials continue to signal a readiness to act against excessive currency weakness. This means the risk of sudden JPY strength is much higher now than it was a year ago. On the Australian side, the energy price pressures that were building in 2025 did contribute to persistent inflation. Australian CPI has remained stubbornly above target, currently sitting at 3.4%, forcing the Reserve Bank of Australia to maintain its cash rate at 4.35%. This wide interest rate differential continues to attract carry traders to the currency pair. The severe geopolitical risks in the Middle East that dominated headlines last year have since evolved into a state of chronic, low-level tension. While WTI crude oil has stabilized in the $78-$82 per barrel range, the threat to Red Sea shipping lanes remains, creating an environment where energy prices can spike on any given headline. This ongoing risk continues to weigh on the growth-sensitive Australian Dollar. For derivative traders, this environment suggests focusing on volatility rather than pure direction. Purchasing options strategies like straddles, which profit from a large price move in either direction, could be effective. This allows a trader to capitalize on a potential breakout without needing to predict if it will be triggered by BoJ intervention or a global risk-off event. The attractive yield differential still supports the long AUD/JPY carry trade, but the rapid reversals we witnessed in 2025 highlight its inherent risk. Traders maintaining long positions should consider hedging this downside exposure. Purchasing out-of-the-money JPY call options can provide a cost-effective insurance policy against a sudden surge in the Yen. Create your live VT Markets account and start trading now.
