What are the key takeaways from this Marketplace episode?

Key insights include: **CPI vs. PCE Gap:** The Fed targets the PCE deflator, not CPI, and right now a notable gap exists between the two measures. Current CPI data implies PCE inflation is running hotter than CPI suggests. Investors watching CPI for rate-cut signals should monitor PCE separately, as that is the metric actually driving Fed decisions.; **Energy Price Lag:** Gasoline prices rose in February before the Iran conflict began, reflecting oil markets already pricing in Middle East escalation risk. The March CPI report will capture the full shock. Natural gas is up 10.9% year-over-year, and a fifth of global supply now faces disruption through the Strait of Hormuz.; **Tariff Deflation Paradox:** San Francisco Fed research spanning 150 years finds tariffs can reduce inflation by slowing economic activity rather than raising prices. Uncertainty causes households and firms to cut spending, companies freeze hiring, and reduced demand suppresses prices — meaning tariff-driven disinflation signals economic weakness, not stability, and warrants close monitoring of labor market data.

What did Nicole Servie discuss on Marketplace?

February's CPI showed 2.4% annual inflation — a five-year low — but economists at Wells Fargo, KPMG, and Rice University explain why the report is largely outdated due to the Iran conflict, rising energy costs, and tariff uncertainty reshaping the inflation outlook before March data even arrives.

Key Takeaways

✓CPI vs. PCE Gap: The Fed targets the PCE deflator, not CPI, and right now a notable gap exists between the two measures. Current CPI data implies PCE inflation is running hotter than CPI suggests. Investors watching CPI for rate-cut signals should monitor PCE separately, as that is the metric actually driving Fed decisions.
✓Energy Price Lag: Gasoline prices rose in February before the Iran conflict began, reflecting oil markets already pricing in Middle East escalation risk. The March CPI report will capture the full shock. Natural gas is up 10.9% year-over-year, and a fifth of global supply now faces disruption through the Strait of Hormuz.
✓Tariff Deflation Paradox: San Francisco Fed research spanning 150 years finds tariffs can reduce inflation by slowing economic activity rather than raising prices. Uncertainty causes households and firms to cut spending, companies freeze hiring, and reduced demand suppresses prices — meaning tariff-driven disinflation signals economic weakness, not stability, and warrants close monitoring of labor market data.
✓Natural Gas US Shield: Despite global natural gas price spikes driven by interrupted Middle Eastern LNG exports, US consumers remain largely insulated because North America is self-sufficient in production. Seasonal demand drops in April should bring domestic prices down further, offering near-term household utility bill relief compared to Europe and Asia.
✓Fed Rate Path: Wells Fargo economist Nicole Servie argues the Fed will hold rates at current levels longer than previously anticipated. Disinflationary progress has stalled — year-over-year CPI and core CPI moved sideways in February — and an incoming energy price shock makes further restrictive policy the most likely outcome through at least mid-2025.

Notable Moment

Egg prices dropped over 40% month-over-month in February, but food economists note this relief is effectively canceled out for household budgets because Americans spend roughly five times more on beef than eggs — and beef prices continue climbing due to the smallest US cattle herd since the 1960s.

From Minnesota Public Radio in Saint Paul, I'm Kimberly Adams in for Kai Rizdahl. It's Wednesday, March 11. Good to have you along. I'm at 8PM headquarters today instead of my normal spot in DC. But back in the nation's capital, this morning, we got the latest read on inflation from the Federal Bureau of Labor Statistics. The consumer price index registered just a 0.3% increase in the month of February. Over the past twelve months, prices rose 2.4%. That's the lowest reading in five years. But there are, as is so often the case, some caveats to what seems like encouraging news. Here to give us her expert opinion on the report is Nicole Servie, an economist for Wells Fargo corporate and investment banking. Welcome back to the show. Thanks for having me. Can I just get your quick reaction to the top line numbers? Yeah. So in terms of the month over month, those looked pretty good. But if you look at, for instance, the year over year rates of CPI and core CPI, they both moved sideways. And what the report suggests to me is that, yes, inflation is not as bad as we had feared by this point in time, but we're also not seeing progress either. And now we gotta think about this energy price shock. And so while this report is encouraging, I do think it feels a little dated at this point in time, especially once we turn to the March CPI and get some of that immediate reaction to what we're seeing in the conflict in The Middle East. Right. This is the giant asterisk on this report, which is that all of this data was before we went to war with Iran. Correct. And so how are economists, do you think, factoring that in when …
