The official headline CPI of 2.4% is artificially low due to a measurement error from the October government shutdown. When corrected, the true year-over-year inflation rate is closer to 2.7-2.8%. This means underlying inflation is still hovering near 3%, significantly above the Federal Reserve's 2% target.

The new Fed chairman prefers a "trimmed mean" inflation gauge which currently reads lower than traditional measures. By excluding items like energy, this change provides political cover to cut interest rates before an election, even if underlying inflation remains high, effectively moving the goalposts to suit a policy objective.

After accounting for measurement quirks in both CPI and PCE, the podcast's economists converge on an estimate for "true" underlying inflation around 2.7-2.8%. This consensus view suggests that while official measures are noisy, the underlying trend is still meaningfully above the Fed's 2% target.

The gap between Core PCE (3.3%) and Core CPI (2.5%) inflation is driven by how each index weighs shelter and measures financial services. CPI gives more weight to disinflating shelter, while PCE is inflated by a stock market-linked measure for financial services.

Despite a downside surprise in CPI, the Fed's preferred inflation gauge, Core PCE, is still rising. This growing negative wedge between the two metrics leads to a more hawkish Fed policy than CPI alone would suggest, creating a negative outlook for TIPS in the near term.

A significant, yet overlooked, factor pushing inflation higher is demand related to Artificial Intelligence. This effect is amplified within key price indices like the PCE due to mismeasurement, contributing to the persistence of inflation figures staying closer to 3% rather than the Fed's 2% target.

A measure of "market-based core PCE services ex-housing" inflation is accelerating. This niche metric, which strips out imputed prices and volatile sectors, suggests that core economic activity is generating persistent inflation, challenging narratives focused solely on energy shocks or trade wars.

High measured inflation figures are misleading due to "quirks of measurement." For example, rising stock market values in portfolio management services artificially inflate reported inflation. Correcting for these biases reveals a less problematic inflation picture, justifying a more supportive monetary policy for the labor market.

The Bureau of Economic Analysis will soon change how it calculates financial services prices for the PCE deflator. It's moving from a stock market-based measure to one based on wages, a change expected to reduce year-over-year Core PCE by 0.1-0.2 percentage points.
