CPI at 3.3%: Why the Inflation Panic Is Wrong
Key Takeaways
- Core CPI at 2.6% year-over-year shows the underlying disinflation trend is intact despite the headline spike to 3.3%.
- The March inflation surge was almost entirely driven by a 21.2% gasoline spike — a geopolitical supply shock, not demand-driven overheating.
- Energy shocks have a finite duration: oil is already off its highs and US-Iran negotiations offer a path to Hormuz reopening.
- The Fed should cut rates in 2026 — restrictive policy can't fix a supply disruption and risks unnecessary damage to a cooling economy.
- Long-duration bonds at 4.29% on the 10-year offer the best entry point in two years for investors willing to look past temporary noise.
March CPI hit 3.3% and the financial media promptly lost its mind. Rate-cut hopes are dead. Stagflation is back. The 1970s are repeating. Here's the problem with that narrative: strip out energy, and inflation actually improved.
Core CPI — the measure the Fed actually targets — came in at 0.2% month-over-month, matching February's pace. Year-over-year core sits at 2.6%, barely above the Fed's 2% target. Food prices were flat. Used car prices fell. Prescription drug costs declined. The inflation problem in March 2026 has exactly one name: gasoline.
Gas prices spiked 21.2% because the Strait of Hormuz shut down. That's a supply disruption, not a demand-driven inflation cycle. Every supply-driven energy shock in modern history has reversed once the disruption resolved. Oil is already 30% off its highs. The panic trade is the wrong trade.
Core Inflation Tells the Real Story
Headline CPI is a blunt instrument. It treats a geopolitical supply shock the same as a genuine overheating economy. The Fed knows the difference, which is exactly why core PCE — not headline CPI — is their preferred gauge.
Core CPI at 2.6% year-over-year is within striking distance of the 2% target. Six months ago it was 2.8%. The trend is clearly downward. One month of energy-driven headline noise doesn't reverse 18 months of disinflation progress.
Look at the categories: grocery prices fell 0.2% in March. Used cars and trucks declined year-over-year. Medical care costs are dropping. These are the categories that reflect actual demand conditions, and they're all pointing the same direction — down. The hawks are cherry-picking one month of headline data to declare victory while ignoring the entire underlying trend.
This Energy Shock Has an Expiry Date
The Strait of Hormuz disruption is a discrete event, not a permanent structural change. US-Iran negotiations are ongoing. Oil prices have already retreated from their peaks. The market is pricing in reopening risk, not permanent closure.
Compare this to 2022. Russia's invasion of Ukraine produced a sustained energy shock because Western sanctions created a structural rerouting of global energy trade. The Iran situation is fundamentally different — it's a military blockade with active diplomatic channels. Once shipping resumes, supply normalises within weeks, not years.
The 2022 energy shock pushed headline CPI above 9%. It took 18 months to resolve, but it did resolve — without permanent damage to core inflation. The current shock is smaller in magnitude and more likely to be shorter in duration. Extrapolating one month's gasoline spike into a permanent inflation regime change is the same mistake analysts made in 2022, and they were wrong then too.
The Fed should — and will — look through temporary supply shocks. That's monetary policy 101.
The Economy Needs Rate Relief
The fed funds rate at 3.50-3.75% is restrictive. Real rates — the gap between the policy rate and core inflation — are positive by roughly 100 basis points. That's a meaningful drag on economic activity, housing, and business investment.
Consumer sentiment just hit a record low per the University of Michigan survey. Housing starts have slumped. Small business lending remains constrained. These are signs of an economy that needs monetary easing, not an economy that's overheating.
Holding rates at restrictive levels to fight a supply-driven energy spike would be the worst possible policy response. It would crush demand without affecting the source of inflation — which is a blocked shipping lane in the Persian Gulf, not excessive consumer spending. The Fed made this exact mistake in 2008, tightening into a commodity spike while the real economy was already weakening.
The 10-year Treasury at 4.29% and the 2-year at 3.79% create a 50 basis point positive spread. That's a yield curve saying growth and inflation expectations are moderate — not a curve screaming overheating.
Tariff Inflation Is Fading, Not Building
The hawks love bundling tariffs with energy into a dual-threat narrative. The data tells a different story. The effective tariff rate has dropped from 21% in April 2025 to roughly 8% today. That's a 62% decline in the tariff burden in 12 months.
More importantly, the pass-through from tariffs to consumer prices has largely run its course. Firms adjusted pricing in 2025 when the tariff rate peaked. Those adjustments are now in the base, which means they're rolling out of year-over-year comparisons. Tariffs are a headwind for the level of prices but not for the rate of change — and the rate of change is what matters for inflation.
Goods deflation, driven by supply chain normalisation and falling import costs, is offsetting whatever tariff residue remains. The March data confirms this: core goods prices are flat to declining across most categories.
The Smart Money Is Buying Duration
Everyone running from bonds right now is making the classic mistake of fighting the last war. If the energy shock resolves — and it will — headline CPI falls back toward 2.5% within two to three months. Core continues its drift toward 2%. The Fed cuts at least once, possibly twice before year-end.
At 4.29%, the 10-year Treasury offers a real yield of roughly 1.7% above core CPI. That's the most attractive entry point for long-duration bonds since early 2024. When the inevitable reversal in oil prices comes, the flight from inflation trades back into bonds will be swift.
Rate-sensitive equities — homebuilders, REITs, growth tech — are being punished for a temporary shock. Those are buying opportunities, not sell signals. The market is offering a gift to anyone willing to look past one month of energy-driven headline noise and focus on the trend that actually matters: core inflation falling toward target while the economy cools.
Conclusion
The March CPI report scared people who only read headlines. The number that matters — core CPI at 2.6% — tells a story of disinflation continuing on schedule. Gas prices spiked because of a geopolitical event with a finite duration, not because the economy is overheating.
The Fed should cut rates this year, and I expect they will — once the energy shock passes and the headline noise clears. Investors who position for a prolonged inflation regime are betting against 50 years of evidence that supply-driven energy spikes are temporary. Buy duration, buy rate-sensitive assets, and ignore the panic.
