A methodological catch-up by the Bureau of Labor Statistics after a government shutdown artificially inflated the most recent monthly shelter CPI figure. However, this correction means the year-over-year inflation rate is now a more accurate reflection of reality, after being suppressed in previous months.

Despite progress on shelter inflation, core services excluding shelter (the "super core") remain sticky. This persistence, linked to wage components, is a primary reason the Federal Reserve will likely pursue a gradual pace of interest rate cuts rather than a more aggressive easing policy.

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 missing October CPI data significantly impacted the report because of how shelter—the largest component—is measured. The Bureau of Labor Statistics uses a six-month rolling panel. By imputing a zero change for the missing month, it artificially dragged down the entire index in a way that simply measuring prices from September to November could not correct.

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.

The CPI averages costs across 80,000 items, many of which are non-essentials or luxury goods. This method masks the true, higher inflation rate on basic necessities. For example, while the CPI showed a 72% cost increase over two decades, the actual cost of essentials like housing, food, and healthcare rose by a much larger 97%.

Despite official CPI averaging under 2% from 2010-2020, the actual cost of major assets like homes and stocks exploded. This disconnect shows that government inflation data fails to reflect the reality of eroding purchasing power, which is a key driver of public frustration.

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.

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.
