The BEA is using September and November CPI data to compute the October PCE price figures. This methodology matters more than you'd think, especially if you're tracking macro trends that move markets.

When official data points are missing or delayed, statisticians often interpolate using surrounding months—and that's exactly what's happening here. The October PCE reading will be derived from a simple average of Q3 and Q4 inflation snapshots.

Why does this hit your radar? PCE is the Fed's preferred inflation gauge. If they're estimating October PCE this way, traders need to understand that the actual number carries some interpolation uncertainty. It's not raw data—it's methodology.

For anyone tracking macro cycles, rate expectations, or broader market sentiment: this is a reminder to check the fine print on official statistics. The calculations behind the numbers matter as much as the numbers themselves.
