PCE's Cooling Sentiment Shifts Rate Cut Expectations and Markets

The US Federal Reserve has one key inflation number that affects Australian traders, but it's not the Consumer Price Index (CPI) or the unemployment rate. It's PCE - the Personal Consumption Expenditures Price Index.

PCE is a three-letter acronym representing a specific inflation measure the Fed targets. When it runs hot, rate cuts get pushed back, the US dollar strengthens, AUD/USD falls, and gold comes under pressure. Conversely, when PCE cools, the opposite happens across all three instruments.

The July 31 PCE release was a key event for Australian traders, as it cooled alongside a softer-than-expected Q2 GDP report. This led to a repricing of a September rate cut from 60% to 85%, sending both AUD/USD and gold higher in the sessions that followed.

A structural change is happening to PCE itself - the Bureau of Economic Analysis is reformulating its calculation methodology, which will lower the measured PCE inflation reading going forward. If implemented, this could shift market expectations for the pace of rate cuts in 2026 and 2027 toward a faster easing cycle.

AUD/USD is directly affected by every PCE release, with the pair rallying when PCE cools and rate cut expectations build. The next PCE release on August 29 will be closely watched for further cooling prints, which could send AUD/USD toward retesting the 0.7200 to 0.7250 resistance zone.
