AUD/USD Plummets: Risk Flows and Oil Prices Crush Aussie

The primary driver is a clear flight to safety. AUD/USD fell below 0.6900 for the third straight day, down 0.76%, as investors rushed into the US Dollar amid fears of Middle East escalation. This risk-off flow is the dominant market driver, overshadowing the upcoming RBA Minutes.

The move accelerated on a spike in oil and gasoline prices. Year-to-date, WTI crude is up 64% and gasoline nearly 80%, reinforcing Dollar strength. The energy shock, linked to expectations of a quasi-closure of the Strait of Hormuz, directly pressures commodity currencies like the Aussie. The US Dollar Index (DXY) edged up 0.37% to 100.00, with US Treasury yields rising to underpin the Greenback.

Stable US labor data and higher yields added pressure, but the geopolitical catalyst is the key. Wall Street finished the session in the red, and the technical breakdown below 0.6900 triggered stop-loss orders, accelerating the sell-off. The setup points to further downside, with the next major support near 0.6850.

RBA Policy: A Secondary Factor Amid External Shocks

The RBA's policy path is a secondary factor in today's AUD/USD move. The central bank raised its cash rate target to 3.85 per cent last month, citing inflation above target and capacity pressures. This action was a direct response to domestic economic momentum, not the current geopolitical shock.

Major banks now forecast two more 25bp hikes in March and May 2026, driven by concerns over imported inflation from the Middle East conflict. The RBA's Monetary Policy Board has signalled it will react to spikes in headline inflation to prevent a sustained rise in expectations, even if the oil shock is temporary. This sets up a potential policy tightening cycle independent of the currency's external pressures.

Yet the RBA's primary focus remains domestic. Its communication shows it has not changed its view on limited supply capacity, and it has not allowed for any disinflation from a USD selloff separate from domestic rate moves. In this context, the external oil shock and risk-off flows are overwhelming the central bank's domestic mandate, making its policy stance a secondary influence on the immediate currency flow.

Catalysts and Key Levels: What to Watch

The immediate technical setup points to further downside. The pair has broken below 0.6900 and is testing the next major support at 0.6850, a level not seen since late 2024. A decisive break below that zone would open the path toward the December 18 low of 0.6592, which represents a deeper floor for the currency. The technical breakdown, including a bearish "death cross" on moving averages, suggests the sell-off momentum is intact.

The RBA Minutes, due in a few hours, will reveal internal debate on external risks but are unlikely to change the immediate flow. The minutes will detail the board's discussion on inflation and the exchange rate, but the overwhelming external shock from Middle East tensions and oil prices is dictating the market's direction. Any hawkish tilt on inflation would be overshadowed by the risk-off sentiment, making the Minutes a secondary catalyst for the pair.

The key external catalyst to watch is a shift in Middle East ceasefire talks and oil price stabilization. The current sell-off is a direct function of a risk-off flow into the US Dollar, fueled by fears of a quasi-closure of the Strait of Hormuz. A tangible de-escalation in the region and a reversal in the 64% year-to-date surge in WTI crude would be required to reverse the flow and provide relief for commodity currencies like the Aussie. For now, the path of least resistance remains lower.
