Will monthly inflation stay flat (0.0%) or decrease in September?

The question asks whether the monthly CPI-U change for September 2026 will be 0.0% or negative (i.e., flat or decreasing). The only provided article discusses Australian interest rate policy and the RBA, not U.S. CPI data. It mentions that an economist expects rates to stay higher for longer to bring inflation down, which suggests a general disinflationary trend, but it does not provide any specific forecast for U.S. CPI in September 2026. Without any direct evidence about the U.S. CPI release for that month, the available information is insufficient to make a confident prediction. Therefore, the probability is set at 0.5, reflecting maximum uncertainty given the lack of relevant data.
