What was the March 2026 CPI report?

The Bureau of Labor Statistics reported March 2026 CPI on April 10, 2026. Headline CPI rose 0.9% month-over-month and 3.3% year-over-year. Gasoline prices jumped 21.2% on the month, energy overall rose 10.9%, and core CPI (excluding food and energy) rose just 0.2%. Energy alone explained roughly three-quarters of the headline increase.

Why did gas prices spike in March 2026?

The gasoline index rose 21.2% MoM in March 2026, driven by crude oil supply disruptions and refinery tightness carrying over from the Iran-related oil shock earlier in the year. The national average pump price crossed $4/gallon in most metros. Because gasoline is in the BLS energy index, and energy gets about a 7% weight in the headline CPI basket, a 21% monthly move moves the headline number by roughly 1.5 percentage points on a pure arithmetic basis — partly offset by other declines.

What is the difference between headline and core CPI?

Headline CPI includes all goods and services the BLS tracks. Core CPI excludes food and energy, the two most volatile categories. Economists and the Federal Reserve watch core CPI because it's a better signal of underlying inflation trend. In March 2026, headline CPI was 0.9% but core was only 0.2% — suggesting the spike was a one-off energy shock rather than a broad reacceleration.

How does the CPI report affect mortgage rates?

Hot CPI prints usually push Treasury yields higher, and mortgage rates move with the 10-year Treasury. But when the heat is concentrated in energy and core stays tame, bond markets often look through it. After the March 2026 CPI print, the 10-year Treasury ended near 4.29% and the 30-year fixed mortgage actually fell slightly to 6.30% — markets read the report as a supply shock, not a demand-driven reinflation.

How do I calculate my personal inflation rate?

The headline CPI is an average across 130+ million US households. Your actual inflation rate depends on how much you spend on each category. A household that drives 25,000 miles a year and heats a large home with oil will feel the March 2026 energy spike as much as 3–4% on their personal budget. A remote worker who drives 3,000 miles will feel closer to 0.3%. Use our inflation calculator to weight BLS sub-indexes against your own spending mix.

Is inflation getting worse in 2026?

On the headline number, yes — March 2026's 3.3% YoY is the highest reading in over a year. But core CPI running at 0.2% MoM annualizes to about 2.4%, which is near the Fed's 2% target. The Mortgage Bankers Association recently removed Fed rate cuts from its 2026 forecast and now expects inflation to settle near 4% if energy stays elevated. The honest read: energy-driven headline pressure, but no broad second-round effects yet.

March 2026 CPI Jumps 0.9%: Gas Drove Three-Quarters of the Spike

Gasoline	+21.2%	+24.6%
Food	+0.3%	+2.8%
Shelter	+0.3%	+3.6%
Core (ex food and energy)	+0.2%	+2.9%

Why gasoline alone explains 75% of the headline jump

Energy has roughly a 7% weight in the CPI basket, and gasoline is about 3.3% of that basket. When gasoline rises 21% in one month, the pure arithmetic contribution is about 0.70 percentage points to the headline. Broader energy (electricity, natural gas, fuel oil) added another ~0.2 points. Out of a 0.9% headline move, roughly 0.7 points — about 75% — came from energy. Everything else combined contributed about 0.2 points, which matches what core CPI printed.

What $4+ gas does to a typical household budget

The average US household consumes about 1,050 gallons of gasoline per year. A price move from $3.30 to $4.00 per gallon costs that household an extra $735/year at the pump. Two-car commuter households easily double that. Here is the approximate monthly hit at different driving profiles:

Driver profile	Annual gallons	Extra cost at +$0.70/gal
Remote worker, 1 car	~200	~$140/year
Average household	~1,050	~$735/year
Two commuters	~1,800	~$1,260/year
Rural / long commute	~2,500	~$1,750/year

Headline vs core: why economists watch the quieter number

Headline CPI tells you what you paid. Core CPI tells you whether inflation is embedded in the broader economy. Energy prices move on OPEC decisions, refinery outages, and geopolitics — factors outside the Fed's control. If core stays near 2–3% while headline spikes on energy, central bankers typically look through it. That is exactly what bond markets did this month: the 10-year Treasury ended near 4.29% after the CPI print, and the 30-year fixed mortgage rate actually fell to 6.30% (Freddie Mac PMMS), a four-week low.

The second-round risk to watch

Energy shocks stay contained when they reverse quickly. They become a problem when they persist long enough to feed into:

Transportation services: airfare, trucking, delivery. These lag gasoline by 1–3 months.
Food at home: diesel is a major cost input. Sustained +20% fuel prices typically add 0.5–1.5 points to food inflation over 6 months.
Wage demands: if workers factor higher commuting costs into pay negotiations, you get a wage-price loop.

The Mortgage Bankers Association's Mike Fratantoni recently removed 2026 Fed rate cuts from the MBA forecast and now expects inflation to settle near 4% if energy stays elevated through the summer driving season.

Your personal inflation rate is probably not 3.3%

Headline CPI averages across every US household. If you drive a lot, your personal rate right now is meaningfully higher than 3.3%. If you work from home and rent-controlled, it is meaningfully lower. A rough personal-rate formula: multiply each BLS sub-index YoY change by your share of spending in that category, then sum. Our Inflation Calculator does this with BLS weights, and our Inflation Price Calculator lets you translate any price from one year into today's dollars.

Frequently asked questions

What was the March 2026 CPI number?

Headline CPI rose 0.9% MoM and 3.3% YoY. Core CPI rose 0.2% MoM and 2.9% YoY. Gasoline rose 21.2% MoM.

Why did the headline jump so much?

Energy prices, mostly gasoline. Energy alone explained about 75% of the 0.9% headline move. Core inflation stayed tame at 0.2%.

Will the Fed cut rates in 2026?

Probably not. The Mortgage Bankers Association has removed 2026 rate cuts from its forecast. The Fed is expected to hold the policy rate at 3.5–3.75% through the year if energy-driven inflation persists.

What happened to mortgage rates?

The 30-year fixed fell to 6.30% (Freddie Mac PMMS) — a four-week low. Bond markets treated the CPI print as a supply shock, not a demand-driven reinflation.

How do I figure out my personal inflation rate?

Weight each BLS sub-index by your share of spending in that category. Our inflation calculator does the math with BLS CPI-U weights.
