The AUD/JPY cross fell to approximately 103.20 during Asian trading hours. This decline followed the Reserve Bank of Australia’s decision to maintain its interest rate at 3.6%.
The RBA noted that rising inflation might be temporary but would need careful monitoring. Meanwhile, the impact of a recent earthquake in Japan could affect the Yen and influence future interest rate adjustments by the Bank of Japan.
Influencing Factors on Australias Currency
Australia’s currency movements are influenced by interest rates, Iron Ore prices, and Chinese economic health. High interest rates typically support the Australian Dollar, while lower rates have the opposite effect. Iron Ore, a major export, also affects the currency’s strength, with price increases supporting the AUD.
Australia’s Trade Balance, the difference between export earnings and import costs, can bolster the AUD if positive. As China is a key trade partner, its economic health significantly impacts the Australian Dollar’s value. Positive or negative shifts in China’s growth often have direct effects on AUD.
Overall, the stability and value of the Australian Dollar are reliant on various economic factors, such as monetary policy, trade dynamics, and external economic conditions, particularly in China.
We see the Reserve Bank of Australia holding its cash rate at 3.6%, continuing the pause that began earlier in 2025. This decision was expected, as Australian inflation has cooled significantly from its 2023 peaks to a more manageable 3.1% in the latest quarterly reading. This firmly signals that the RBA’s next move is more likely a cut than a hike, putting sustained pressure on the Australian dollar.
Market Responses and Strategies
All attention now shifts to the Bank of Japan’s policy meeting scheduled for December 18-19. We recall their landmark decision in March 2024 to finally end negative interest rates, and the market had been slowly pricing in another small hike this month. The recent earthquake, however, complicates this, as the central bank may choose to delay tightening to ensure financial stability.
The outlook for the Aussie dollar is also weakened by external factors, particularly slowing demand from China. Recent data showed China’s November 2025 manufacturing PMI dipped to 49.8, indicating a slight contraction and causing iron ore prices to pull back to around $115 per tonne. This removes a key source of strength for the AUD that we saw for much of 2024.
For the coming weeks, we should consider buying AUD/JPY put options with expirations after the BoJ meeting. This is a direct way to position for further downside if the BoJ surprises the market and proceeds with its rate hike. This strategy offers a defined-risk approach to a potentially stronger yen and a fundamentally weaker Aussie.
Alternatively, if we believe the earthquake will force the Bank of Japan to adopt a more dovish tone and hold rates, the AUD/JPY could see a sharp short-term rally. In this case, short-dated call options could be a cost-effective way to capture that potential upside. This trade would profit from the market being caught off guard by a dovish BoJ.
Given the uncertainty, an options straddle, which involves buying both a put and a call at the same strike price, could be an effective strategy. This position will profit from a significant price move in either direction following the BoJ announcement. It allows us to trade the expected increase in volatility without needing to predict the outcome of the meeting.
