Overview: A Heavy Calendar Day for AUD and USD
September 30, 2026 is one of the most data-rich sessions of the month. Two major central-bank-relevant inflation prints — Australia’s August CPI and the U.S. Core PCE Price Index — land on the same day, alongside the U.S. Final GDP and ADP employment data. Taken together, these releases carry the potential to set the directional tone for AUD/USD, EUR/USD, and broader USD pairs heading into the final quarter of 2026. Traders should approach today with a plan for elevated volatility windows and wider-than-normal spreads around each release.

HIGH-IMPACT: Australian CPI (1:30am UTC)
The Setup: Post-RBA Hike Inflation Read
Australia’s August CPI data — covering CPI m/m, CPI y/y, and Trimmed Mean CPI m/m — is the first major event of the session, releasing at 1:30am UTC via the Australian Bureau of Statistics (ABS). The timing is critical: this data arrives just one day after the Reserve Bank of Australia (RBA) raised its cash rate by 25 basis points to 4.60% on September 29, 2026, its fourth hike of the year and the highest rate level since November 2011, according to the RBA’s official statement.
The forecasts are as follows:
- CPI m/m: forecast 0.5%, previous 1.0%
- CPI y/y: forecast 4.1%, previous 3.5%
- Trimmed Mean CPI m/m: forecast 0.3%, previous 0.5%
The annual rate is expected to jump sharply to 4.1% from 3.5% in July — a meaningful acceleration that, if confirmed, would reinforce the case for additional RBA tightening. According to investinglive.com, market consensus ahead of today’s print is for headline y/y inflation at or around 4.0%–4.1%, with trimmed mean expected to hold steady at around 3.6% annually. The monthly CPI figure is actually forecast to cool sharply — 0.5% m/m versus the 1.0% surge seen in July — which partly reflects seasonal factors.
As noted by CNBC, Bank of America warned last week that “inflation was accelerating rather than converging back to target,” and the RBA’s own statement on September 29 cited materialising upside inflation risks, including higher global energy prices and AI-driven technology goods inflation. According to the RBA statement, the board stated it “will continue to do what it considers necessary” to contain inflation, including further rate increases if needed. ANZ, according to SBS News, expects a potential fifth RBA hike in November.
Trading Read: AUD/USD Volatility Risk
AUD/USD entered today under clear pressure. According to FXStreet, the pair was trading at 0.6987, having broken below the psychologically important 0.70 handle, and sits below a clustered group of 50-, 100-, and 200-day simple moving averages near 0.7093, which now act as significant resistance. FXStreet also noted the 14-period RSI had slipped toward the 30 region, suggesting emerging oversold conditions, though this alone does not reverse the bearish trend while price remains capped by those moving averages.
For today’s CPI release, the key question is whether the trimmed mean — the RBA’s preferred underlying inflation gauge — surprises to the upside or the downside:
- Beat (higher than forecast): A y/y print above 4.1% or a trimmed mean above 0.3% m/m would strengthen the case for a fifth RBA hike and could provide a short-term lift to AUD/USD. However, given the pair’s bearish technical backdrop, any rally is likely to face supply near the 0.7093 moving average cluster, per FXStreet analysis.
- In-line: An on-forecast result would probably deliver a muted reaction. Markets have already priced a hawkish RBA, so confirmation without surprise may simply stabilise AUD/USD at current levels.
- Miss (softer than forecast): A materially weaker trimmed mean would invite speculation about whether the RBA needs to go as far as markets currently price — potentially accelerating AUD/USD’s slide below 0.70. According to investinglive.com, “a softer result, particularly in trimmed mean, would invite doubts about how far the central bank needs to go.”
The 1:30am UTC release time means liquidity will be relatively thin (Asian session), which can amplify the initial spike in either direction. Scalping indicators and tight risk controls are especially important around illiquid-session data releases like this one. Traders should watch for a 20–40 pip initial whipsaw before a cleaner directional move establishes itself. Also worth reading for context: yesterday’s analysis covering the RBA rate decision and its immediate market impact on AUD/USD.
HIGH-IMPACT: US Core PCE Price Index & Final GDP (12:30pm UTC)
Core PCE: The Fed’s Preferred Inflation Gauge
At 12:30pm UTC, the Bureau of Economic Analysis (BEA) publishes the August Core PCE Price Index. As confirmed by the BEA’s official release calendar, today is the scheduled release date for this data. The forecast is 0.3% m/m, up from the prior reading of 0.2%. As the Federal Reserve’s preferred inflation measure, this figure carries more direct policy weight than the CPI, and today’s print will be closely scrutinised by markets trying to assess whether the Fed needs to hike rates again at its October 28 meeting.
According to Yahoo Finance, the July Core PCE came in at 0.2% m/m (matching expectations), and the BEA had previously noted the next release covering August data was scheduled for September 30. The prior month’s in-line print had led markets to cut September Fed hike odds — but with the forecast now ticking up to 0.3%, today’s release is genuinely uncertain. According to investing.com, the forecast for today’s release confirms the 0.3% m/m expectation. The Fed’s own updated projections, per Bloomberg, raised the 2026 core PCE forecast to 3.4%.
- Beat (above 0.3% m/m): Would be interpreted as stubbornly persistent inflation, reinforcing the case for further Fed tightening. This scenario is USD-bullish and would likely weigh on EUR/USD, GBP/USD, and gold simultaneously.
- In-line (exactly 0.3%): A neutral-to-mildly USD-positive outcome. The uptick from 0.2% still signals inflation is not slowing as fast as the Fed would like, but an in-line number usually produces a shorter-lived reaction.
- Miss (below 0.3%): If the print comes in at 0.2% or lower, markets would likely interpret this as progress toward the Fed’s target, reducing the urgency of additional hikes. This would be USD-negative and could provide a relief rally in risk currencies including AUD/USD and EUR/USD.
EUR/USD is approaching today’s US data from a position of multi-month weakness. According to Yahoo Finance data, the pair was quoted near 1.1380, down from its 2026 highs above 1.20. Trading Economics data shows the pair fell to 1.1366 on September 29, its lowest level since July 2026, reflecting a stronger dollar supported by rising US Treasury yields and hawkish Fed expectations. A hot Core PCE print could push EUR/USD toward the 1.1280 region flagged by Daily Forex analysts. Conversely, a softer reading may offer a short-term bounce toward 1.1450. Identifying clean support and resistance levels ahead of the 12:30pm UTC release will be important for managing risk around this event.
Final GDP Q2: Confirmation, Not Catalyst
Also releasing at 12:30pm UTC is the U.S. Final GDP for Q2 2026. The forecast is 1.5% annualised, unchanged from both the previous estimate and the advance estimate published by the BEA in July, which showed the U.S. economy growing at 1.5% in Q2. According to the BEA’s advance estimate, growth was supported by consumer spending, investment, and exports, partly offset by a drop in government spending. A final reading that confirms 1.5% is unlikely to generate significant market reaction — this is largely a backward-looking data point at this stage. A meaningful revision up or down from 1.5% would be the scenario to watch.
MEDIUM-IMPACT: ADP Non-Farm Employment & German Prelim CPI
ADP Employment (12:15pm UTC)
The ADP National Employment Report for September is scheduled for release at 12:15pm UTC (8:15am ET), as confirmed by ADP Research. The forecast is 73,000 private-sector jobs, a significant improvement from the 38,000 jobs added in August — which was the weakest monthly reading since January 2026, according to ADP Research. This release serves as an early indicator of Friday’s official Non-Farm Payrolls report. A result near or above 73K would signal the labour market is recovering after August’s soft patch and would complement a hawkish reading of the Core PCE data. A miss below 50K would raise questions about whether the jobs slowdown is deepening, adding a dovish layer to today’s USD narrative ahead of the Core PCE figure 15 minutes later.
German Prelim CPI (6:29am UTC)
Germany’s preliminary CPI for September releases at 6:29am UTC with a forecast of 0.5% m/m versus the previous 0.2%. According to data from Investing.com, this measure captures changes in consumer prices at Germany’s Federal Statistical Office and is typically a leading indicator for the Eurozone’s own flash CPI. A beat here — inflation accelerating more than forecast in Europe’s largest economy — would be incrementally EUR-positive, potentially slowing the EUR/USD decline ahead of the bigger US data. However, given the ECB’s current posture (ECB President Lagarde had signalled in February 2026 that inflation was expected to stabilize at the 2% target in the medium term, limiting immediate EUR support), the market impact will likely be modest relative to the US afternoon releases.
Session Outlook: A Volatile Day in Two Acts
Today’s confirmed calendar shapes into a two-act session. Act one unfolds in the Asian session around 1:30am UTC with Australia’s CPI — a binary event for AUD/USD given the RBA hiked only yesterday and traders are actively pricing next-meeting odds. Act two is the main event: the 12:15–12:30pm UTC cluster of ADP, Core PCE, and Final GDP, which collectively represent the most significant USD volatility window of the week. Between those two windows, German CPI at 6:29am UTC adds a muted EUR subplot.
On balance, today is a high-volatility session. The combination of post-RBA inflation data in the Asian session and a trio of US macro releases in the New York open creates two distinct, well-separated risk windows — which actually gives active traders cleaner structure than a single chaotic data dump. That said, spreads will widen materially around each release, false breakouts are common in the first few minutes, and positions held through multiple events carry compounding uncertainty.
