The Australian Dollar fell against the US Dollar on Tuesday, trading a few pips above one-month lows near 0.7100. Reduced expectations of a negotiated end to the Iran war, alongside Oil above $100, weakened risk appetite and weighed on the AUD.
Iranian media reported explosions on Qeshm island, adding to weak market conditions. US President Donald Trump said on Monday that serious talks with Tehran are under way, while disputes remain over Iran’s uranium enrichment.
Oil And Geopolitics Weigh On Risk Appetite
Qatar’s Foreign Ministry said there are no arrangements for exporting energy products and that traffic through the Strait of Hormuz has dropped to a trickle versus pre-war averages. Higher Oil prices raised concerns for Australia as a crude importer.
Reserve Bank of Australia minutes from May pointed to a pause after three consecutive rate rises, with the cash rate at 4.35%. Members said the decision allows time to watch developments in the Middle East war, and the AUD fell after the release.
The RBA holds 11 policy meetings a year and aims for inflation of 2–3%. It can also use quantitative easing, which tends to weaken the AUD, and quantitative tightening, which tends to support it.
We are looking back at the situation in 2025, when geopolitical tensions and soaring oil prices crushed the Australian dollar below 0.7100 against the US dollar. That downtrend has continued into the present day, with the AUD/USD now struggling to hold the 0.6650 level as of mid-May 2026. The risk-off sentiment that started last year has clearly had a lasting impact on the Aussie.
Policy Divergence Drives The Downtrend
The divergence in central bank policy, which became apparent then, is now the dominant theme. We see the Reserve Bank of Australia has held its cash rate at the 4.35% level since that pause began in 2025, even as Australia’s latest quarterly inflation figures show a sticky 3.6%. In contrast, the US Federal Reserve has maintained its higher rates in the 5.25-5.50% range, creating a significant yield advantage that continues to attract capital towards the US dollar.
Thankfully, the extreme oil prices seen during the peak of the Mideast crisis in 2025 have subsided, with WTI crude now trading closer to $80 a barrel instead of over $100. While this provides some relief for Australia’s economy, it has not been enough to reverse the Aussie’s fundamental weakness against the greenback. The focus has firmly shifted from oil shocks to the stark interest rate differential between the two nations.
Given this persistent weakness, traders should consider strategies that benefit from a further decline or stagnation in the AUD/USD. Buying put options on the Australian dollar offers a direct way to position for a downward move while strictly defining risk to the premium paid. This allows for participation in downside potential without the unlimited risk of short-selling the spot currency.
The market remains sensitive, so we should also consider using option spreads to manage costs. A bear put spread, which involves buying a higher-strike put and selling a lower-strike one, can reduce the initial cash outlay for the position. This is a prudent approach in an environment where implied volatility could spike again on any surprising economic data or renewed geopolitical headlines.
