Executive Summary
GBP/AUD trades at ~1.8880, having declined approximately 8.3% from an August 2025 peak near 2.0750, representing a clear structural downtrend driven by diverging central bank trajectories.
The RBA raised its benchmark rate to 3.85% in early February — a move accompanied by commentary describing Australian inflation returning to a trajectory that is "not acceptable" — while the BoE held at 3.75% on a razor-thin 5-4 split. The dominant bilateral narrative is a hawkish RBA overwhelming a policy-paralysed BoE: the RBA is the only G10 central bank actively tightening while the BoE is trapped between stagflation and collapsing growth, unable to cut or commit to further hikes. The rate differential has flipped from GBP-positive to GBP-negative — with AUD yielding 10bps more than GBP at the policy rate and 48bps more at the 10Y tenor — a configuration that is historically unusual and structurally supportive of continued GBP/AUD downside. The Iran-US conflict introduces tactical complexity: GBP is a net-energy-importer currency doubly penalised by oil shocks, while AUD's high-beta characteristic adds near-term volatility risk to any bearish GBP/AUD trade.
A new survey of over 30 investment banks forecasts GBP/AUD to trade lower over the year ahead. Our headline stance is Bearish GBP/AUD at both horizons — tactically with conviction 3/5 and strategically with conviction 3/5 — reflecting the rare alignment of opposing central bank regimes, adverse terms-of-trade divergence, and a structural positioning reset that has further to run.
