Sticky at 2.6%: Core Inflation Reignites as Growth Slows to a Crawl

March CPI just confirmed what many hoped wasn’t true: inflation isn’t over, it’s adapting, and many investors may still be missing the underlying shift.

Here’s what the numbers say:
The March 2026 report from the Bureau of Labor Statistics shows Core CPI rose 0.2% month-over-month and 2.6% year-over-year. That’s not a dramatic spike, but it’s a clear sign that the disinflationary trend has stalled. Instead of drifting closer to the Fed’s 2% target, core inflation is re-accelerating, especially across services and shelter, and underlying pressures are proving far more persistent than the market narrative suggests.

What’s driving the stickiness?
Shelter costs continue to be the anchor, housing inflation remains elevated and shows little sign of rolling over. Meanwhile, services inflation is heating up, particularly in medical care and insurance, where input costs are climbing. The days of steady disinflation in core goods are likely behind us; input costs are rising again, and the old tailwinds of supply chain normalization and cheaper imports have faded.

This is a meaningful shift. Where February’s data (+0.2% MoM) was dismissed as a pause, March’s release makes it clear: February marked the floor, not a new cooling trend. The narrative that inflation would smoothly return to target is looking increasingly outdated.

What’s changed?
Geopolitics and tariffs are now feeding inflation in ways the market has been slow to price in. The recent escalation involving Israel, the U.S., and Iran has tightened global energy markets, lifting transportation and utility costs. At the same time, renewed tariffs and trade frictions are driving up import prices, reversing prior gains in goods disinflation. These pressures are no longer isolated to headline CPI, they’re working their way into services, insurance, and logistics, classic markers of cost-push inflation rather than demand overheating.

Growth: The Other Side of the Coin
While inflation is proving sticky, economic growth is weakening. Latest revisions put U.S. GDP growth around 0.5% annualized, well below trend. Real consumer spending is losing steam, and business investment is fading. This is the classic stagflation setup: persistent inflation, but slowing growth.

Affordability: The Real-World Impact
For most households, the pinch is real. Costs for essentials, energy, food, insurance, housing, are outpacing wage growth. Credit card usage is climbing as consumers try to bridge the gap, but discretionary spending is starting to fall. Recent data suggests nearly 80% of households now face affordability strains not because of runaway demand, but due to relentless cost increases in essentials.

The Big Picture
Inflation is no longer just a cyclical story. It’s becoming structural, driven by policy, global supply shocks, and persistent cost pressures. The Federal Reserve faces a rare dilemma: inflation isn’t cooling quickly enough, but growth is eroding beneath the surface. Equity markets, for now, are still clinging to the soft-landing narrative, but bond markets are starting to price in the risk that inflation will remain stubborn.

The real question isn’t whether inflation is falling, it’s what kind of inflation regime we’re entering next. The March CPI is a wake-up call: the drivers of inflation have shifted, and markets that ignore this risk do so at their peril.
