The Reserve Bank of Australia hiked 25 basis points to 4.60% on 23 September 2026 - the highest policy rate in 15 years and the steepest cumulative tightening since the 2010 cycle. Yet AUD/USD collapsed below 0.7000 to 0.69888 on release day and has failed every reclaim attempt since. This is the second textbook post-hike reversal in a decade, and it changes how traders should approach the Australian dollar through Q4.

What Happened on 23 September

The RBA moved unanimously, citing persistently high inflation and a governor’s statement explicitly flagging that further hikes are on the table. Cash rate is now 4.60% versus 4.35% on 16 September, when the Fed raised to 3.75-4.00%. The rate gap has actually narrowed in favour of AUD - from 225bp to 210bp on the top of the Fed range - yet the pair sold off on the news rather than rallying.

Three forces explain the paradox:

  • Fed path more hawkish than RBA. The Fed dot plot showed 16 of 18 participants expecting more hikes through year-end. Even though the RBA is further along its tightening cycle, the direction of travel favours the USD.
  • Risk-off pressure on commodity carry. AUD is a growth-sensitive commodity currency. The escalating US-Iran conflict, Brent above $106 and a soft China PMI reading (released 30 September, ahead of the 1.4% manufacturing print) drag localised sentiment.
  • Position unwinding ahead of PCE. Hedge funds had already built the most crowded RBA-hike short-dated carry trade in 12 months. Unwinds accelerated once Beijing printed soft.

Level Map - Key Supports and Resistances

AUD/USD trades inside a $0.68-$0.73 range after the breakdown. The chart-based playbook:

  • 0.6950 - first immediate support, tested on 25 September.
  • 0.6900 - August swing low; a clean break opens the next leg.
  • 0.6850 - Rabobank’s 3-month target; a technical trigger at 0.68 opens 0.65.
  • 0.6800 - psychological level, 2024 low, and the 200-day moving average cluster. This is the line that separates a healthy pullback from a trend change.
  • 0.7100 - first overhead, prior consolidation.
  • 0.7200 - ANZ year-end fair-value target; needs a positive China print and softer Fed path.
  • 0.7300 - June high, requires a Fed pivot catalyst.

AUD/USD Carry Trade Playbook - 4 Setups

Setup 1: Fade the RBA bounce. Short rallies into 0.7100 with a stop at 0.7150 and a target at 0.6900. Historically, post-RBA-hike rallies have faded within 3-5 sessions in 8 of the last 12 events since 2012.

Setup 2: Breakout retest. A clean break below 0.6800 with follow-through on 0.6780 opens the Rabobank 0.68-to-0.65 extension. Use 0.6820 as your invalidation.

Setup 3: China PMI relief rally. A soft 30 September print (which landed as 51.4, in line with consensus) is now priced. If follow-through prints show an inflection, a bounce to 0.7200 is viable but only with a stop at 0.6900.

Setup 4: Range mean-reversion. Between 0.6850 and 0.7050, buy the 0.6850 dip and sell the 0.7050 fade with 400 pip stops. This is the highest-probability low-risk setup through the PCE release on 30 September.

Catalysts That Move AUD/USD in October

  • 30 September - US PCE inflation. A hot print accelerates the USD bid; a soft print gives AUD a 300-500 pip relief.
  • 2 October - NFP and Governor Lowe testimony. Back-to-back risk events in the same week.
  • 3 October - OPEC+ production meeting. An oil spike is AUD-negative because it pressures China demand.
  • 14 October - US CPI. Sets the tone for the FOMC path.
  • 27-28 October - FOMC decision. The single most important event for the year for AUD/USD; a Fed hike locks the pair near 0.68, a pause opens 0.73.

FAQ

Q: Why did AUD/USD fall when the RBA hiked to 15-year highs?

Because the Fed is expected to hike further (16 of 18 dot plot participants), the rate gap closed. AUD also fell on risk-off pressure from oil above $106 and a soft China PMI.

Q: Where are the key AUD/USD levels to watch after the RBA hike?

Support at 0.6900, 0.6850 and 0.6800 (200-day moving average). Resistance at 0.7100, 0.7200 and 0.7300.

Q: Will the RBA hike again in 2026?

Governor Bullock signalled further hikes are on the table. The next live meetings are 27-28 October, 19-20 November and 30-31 December. The market currently prices a 30-40% probability of a 50bp year-end rate.

Q: What is the AUD/USD trading range for Q4 2026?

Base case is 0.68-0.73 with a skew lower. Bull case (Fed pivot) is 0.75. Bear case (China recession + Fed hikes) is 0.65.
