Executive Summary
The Australian dollar trades at 0.6845 against the US dollar, down 4% from its March 11 high of 0.7127, as the Iran-US war's risk-off impulse overwhelms the carry advantage from Australia's now-highest-in-G10 policy rate. The RBA delivered back-to-back hikes in February and March — raising the Cash Rate to 4.10% with a 5-4 split — making it the only G10 central bank to tighten in 2026, while every other major central bank held during the March 16-19 super-cluster. AUD/USD has been caught in a tug of war: structurally supported by the widest positive AU-US rate differential in over a decade (+71bps at the 10Y), GDP growth of 2.6% (G10-leading), and PPP undervaluation of 5-16%, yet tactically pressured by VIX at 30.6, CFTC positioning at multi-year bullish extremes, DXY at 100.5, and oil at $107-112/bbl which hurts Australia as a net refined-fuel importer despite coal/LNG export gains. Our tactical stance is bearish with moderate conviction — the positioning unwind and risk-off flows dominate the near term — while our strategic stance is moderately bullish, anchored by the strongest rate differential story in G10, structural USD weakness once war premia fade, and PPP undervaluation that provides a floor. The central tension: can the AUD's fundamental superiority reassert once the geopolitical fog clears, or does the war trigger a global recession that drags the highest-beta G10 currency into a deeper correction?
