AUD/USD was trading near 0.7170 on Wednesday, edging lower even after Australia’s monthly Consumer Price Index rose 1% in July versus a 0.8% forecast, pushing the annual rate to 3.5%. The Reserve Bank of Australia’s trimmed mean increased 0.5% on the month and was unchanged at 3.6% year on year, compared with a 3.5% forecast, leaving the Australian Dollar facing a firmer US Dollar.
US support came as Personal Consumption Expenditure inflation held at 3.7% against 3.6% consensus, while core PCE remained at 3.3% as expected; both measures rose 0.2% on the month. Separately, Iran and Oman said they had completed an agreement on managing the Strait of Hormuz, while the US—outside the deal—has threatened Oman over the arrangement. On the chart, AUD/USD printed 0.7171, staying above the 20-period SMA at 0.7164 and the 100-period SMA at 0.7090, with the RSI around 60; resistance is seen at 0.7175 and 0.7188, while support sits at 0.7168, 0.7164 and 0.7160 before 0.7090.
Inflation-Driven Volatility and Trading Risks
High inflation in both Australia at 3.5% and the US with PCE at 3.7% is setting up a classic tug-of-war for the AUD/USD pair. We expect this macroeconomic friction to fuel near-term volatility as both central banks face pressure to keep interest rates elevated. For derivative traders, this means simple directional bets carry much higher risk in the coming weeks.
Options Strategies and Geopolitical Triggers
With the pair currently testing resistance at 0.7188 and holding support above 0.7160, we recommend utilizing iron condors to profit from range-bound trading. Historical options data reveals that AUD/USD one-month implied volatility typically averages around 8.5% to 9.5% during late-August lulls, making option premium selling highly attractive. This strategy allows us to capture premium decay while keeping defined risk parameters on both sides of the market.
Alternatively, traders expecting a geopolitical breakout from the recent Strait of Hormuz developments should consider buying near-the-money straddles. If the AUD/USD breaks past the 0.7188 ceiling, it could quickly rally toward the 0.7250 level, a key resistance area last tested consistently in early 2023. Conversely, a stronger US Dollar could easily drag the pair back down to its 100-period Simple Moving Average near 0.7090.
We must remain cautious as Australia’s core trimmed mean inflation of 3.6% remains well above the central bank’s target. Any hawkish rhetoric from the Reserve Bank of Australia in the coming weeks could spark a sudden upward move. Therefore, we advise setting strict stop-losses on any short call options to protect capital against sudden upside spikes.
