MUFG said the Australian dollar’s rally against the US dollar is showing signs of fatigue, with limited further upside for AUD/USD as global risk appetite cools, China slows and Reserve Bank of Australia policy becomes less influential relative to rising US yields. The currency was described as the second best-performing G10 unit since the US-Iran conflict began at the end of February, while positioning was characterised as record-long and yield dynamics were framed as tilting risks towards a pullback.
US rates were the focal point. The US 2-year yield closed at 4.12% on Friday after a 25bp rise in May to date, marking its highest level since February 2025. Against that backdrop, the daily correlation between AUD/USD and the AU-US 2-year spread was said to have strengthened sharply, implying that an extended period of higher US rates, with the RBA in a watching brief, could weigh further on the pair, even as shifting expectations around a peace deal and Fed rate pricing affect near-term direction.
Fundamental Drivers and Positioning Risks
We believe the Australian dollar’s strong performance against the US dollar is showing signs of exhaustion. The upside for AUD/USD appears limited from here, and we see the risks shifting toward a potential downturn. The fundamental drivers that supported the Aussie are now either weakening or reversing.
The difference in interest rate paths is becoming a major headwind for the currency pair. US 2-year yields just hit 4.12%, a new high for the year, climbing 25 basis points this month alone as recent inflation data proved stickier than expected. Since the Reserve Bank of Australia is seen as being on hold, this widening yield gap in favor of the US will increasingly weigh on the AUD/USD.
External factors are also turning less supportive for the Australian dollar. We are seeing a cooling of global risk appetite, and recent economic data out of China has been underwhelming. For instance, China’s April industrial production grew by 5.6%, missing forecasts and signaling that its economic recovery is losing steam, which is typically negative for the Aussie.
From a positioning standpoint, the trade looks crowded. Speculative positioning data shows that net long AUD contracts held by traders are at the highest level in over two years. When so many are already on one side of a trade, it leaves the currency vulnerable to a sharp sell-off if sentiment shifts.
Market Outlook and Potential Trading Strategies
We expect the market to pay close attention to any data that suggests the RBA has more time to assess its policy. Any signs of Australian economic softness will reinforce the view that the RBA will lag behind the Federal Reserve in its policy stance. This divergence is a core part of our view that the pair will struggle.
Given these factors, we think traders should consider strategies that protect against or profit from a decline in AUD/USD in the coming weeks. Buying put options could be a straightforward way to position for a drop. Alternatively, establishing bear put spreads can offer a lower-cost strategy with defined risk.
While a positive geopolitical development like a peace deal could cause a brief spike higher, we would view such a rally as a selling opportunity. The underlying fundamentals of slowing global growth and diverging central bank policy are likely to reassert themselves. An upward move would simply provide a more attractive level to enter bearish positions.
