Food CPI vs Energy CPI
Food CPI (FRED CPIUFDSL) and Energy CPI (FRED CPIENGSL) are the two non-core components of CPI excluded from core inflation measures due to volatility. March 2026 BLS release (April 10, 2026): food index unchanged month-over-month, +2.7 percent year-over-year (stable trajectory).
Also known as: CPI: Food (food CPI, food inflation) · CPI: Energy (energy CPI)
Why This Comparison Matters
Food CPI (FRED CPIUFDSL) and Energy CPI (FRED CPIENGSL) are the two non-core components of CPI excluded from core inflation measures due to volatility. March 2026 BLS release (April 10, 2026): food index unchanged month-over-month, +2.7 percent year-over-year (stable trajectory). Energy index +10.9 percent month-over-month (led by gasoline +21.2 percent MoM accounting for nearly three-quarters of monthly all-items increase). Energy +12.5 percent year-over-year. Gasoline prices +18.9 percent in March 2026 vs March 2025. Food away from home +0.2 percent MoM; food at home -0.2 percent MoM. The pair captures the two most politically-sensitive inflation components. April 2026 configuration shows extreme energy surge (Iran war oil shock) with stable food.
The April 2026 Configuration
March 2026 CPI release (April 10, 2026): food index unchanged MoM, +2.7 percent YoY. Energy index +10.9 percent MoM, +12.5 percent YoY. Gasoline +21.2 percent MoM (accounting for ~75 percent of monthly all-items increase); +18.9 percent YoY.
Food decomposition: food away from home +0.2 percent MoM; food at home -0.2 percent MoM. Stable food prices reflect post-2022 normalization. Food at home subcomponent showing modest deflation MoM.
Energy decomposition: gasoline +21.2 percent MoM (Iran war supply disruption); energy services (utilities) modest decline MoM. Iran war (February 2026 onset) catalyzed gasoline spike with WTI rising from $73 to $95.85.
The combined April 2026 reading: extreme energy surge with stable food. Energy CPI exceeds food CPI by 9.8pp at YoY level. Configuration is most extreme food-energy divergence since 2008 oil spike. Watch food CPI for transmission lag from energy: typically 3-6 months. If oil sustains above $90 through Q2 2026, food CPI may rise from current 2.7 percent to 3.5-4.0 percent by Q3 2026 reflecting transportation cost passthrough.
Why Food and Energy Are Excluded from Core
Food and energy excluded from core CPI due to volatility. Energy CPI volatility (year-over-year change) typically 15-30 percent annualized. Food CPI volatility 2-5 percent annualized. Compare to core CPI volatility 0.5-1.5 percent annualized.
The excluded components dominate consumer experience but represent only 21 percent of total CPI weight (food 13.5 percent + energy 7 percent). Core CPI captures broader 79 percent of CPI weight with smoother behavior.
For Fed policy, core inflation is preferred metric because: (1) core is less affected by supply shocks (oil disruptions); (2) core captures persistent price pressures more clearly; (3) core is more responsive to monetary policy.
For consumer experience, headline inflation (including food and energy) drives sentiment. Michigan Consumer Sentiment (April 2026 49.8, all-time low) reflects gasoline spike directly. Inflation expectations (Michigan year-ahead 4.7 percent) heavily influenced by gas prices.
The practical implication: food and energy CPI matter politically and for consumer behavior even if Fed focuses on core. April 2026 +12.5 percent energy YoY drives Michigan sentiment crash + inflation expectation surge despite core CPI moderate at +2.6 percent.
The 2026 Iran War Energy Shock
February 2026 Iran war catalyzed energy price surge. WTI rose from $73 (January 2026) to $95.85 (April 2026, +30 percent). Brent similar magnitude.
Energy CPI components most affected. Motor fuel (gasoline): +21.2 percent MoM March 2026 (accounting for ~75 percent of monthly all-items rise). Most visible to consumers; biggest political impact. Fuel oil (heating oil): similar magnitude. Natural gas: less affected (US production cushioned). Electricity: minimal direct impact (5-year average lag from gas to electricity prices).
Energy CPI passthrough to other CPI components. Transportation services (Uber, taxi, airline): 30-90 day lag for ride-share/airline; longer for transit. Energy CPI rise + transportation services rise + supercore CPI rise expected through Q2-Q3 2026. Food at home: 60-180 day lag for transportation costs reflected in grocery prices. Food CPI may rise from current 2.7 percent to 3.5-4.0 percent if oil sustains. Food away from home: 90-180 day lag for restaurant menu price adjustments. Goods CPI: 60-120 day lag for shipping cost passthrough.
The practical implication: April 2026 energy surge has not yet transmitted to broader CPI. Watch May-September 2026 CPI releases for transmission. Iran ceasefire stabilization could compress energy CPI quickly (60-90 days to consumer prices).
Food CPI Drivers
Food CPI dominated by different drivers than energy. Components.
Food at home (~58 percent of food CPI): meat, poultry, fish (16 percent of food CPI); cereals/bakery (12 percent); dairy (12 percent); fruits/vegetables (12 percent); other (6 percent).
Food away from home (~42 percent of food CPI): restaurants and meals away from home.
Key drivers. Agricultural commodity prices: corn, wheat, soybeans, livestock. Affected by weather, disease (avian flu), trade policy. Wage costs: restaurant wage inflation, food processing labor. Transportation costs: fuel, shipping, rail. Tariff impacts: import food prices for fruits/vegetables, seafood, specialty items.
April 2026 food CPI 2.7 percent YoY, near long-run average 2.5 percent. Stable trajectory reflects: (1) commodity moderation post-2022 surge; (2) wage growth normalization; (3) supply chain normalization. Iran war energy spike has not yet transmitted to food CPI.
The practical implication: food CPI provides cleaner inflation signal than energy (less volatile). Sustained food CPI above 3.5 percent typically signals broader inflation persistence. Food CPI below 2 percent signals possible disinflation.
How Food and Energy CPI Diverge
Food and energy CPI typically diverge more than they converge due to different drivers.
Divergence regimes. Energy surge + food stable (current April 2026): supply shock to oil/gas without food impact. Watch transmission lag.
Food surge + energy stable: agricultural commodity shock (drought, disease). Less common.
Both surge: broader commodity supercycle (2007-2008, 2021-2022). Inflationary regime.
Both fall: commodity collapse (2009, 2014-2016, 2020 COVID flash crash). Disinflationary regime.
Long-run correlation between food CPI and energy CPI: 0.30-0.55 (modestly positive). Correlation strengthens during commodity supercycles and weakens during stable regimes.
April 2026 setup: food +2.7 percent YoY + energy +12.5 percent YoY. Energy/food ratio 4.6x (extreme). Configuration suggests Iran war oil shock specific to energy with food temporarily insulated. Mean reversion likely as either: (1) Iran ceasefire stabilizes oil; or (2) food CPI rises with transportation cost transmission.
How the Pair Performs Through Cycles
Three macro cycle examples.
2007-2008 commodity supercycle: food peaked +6.4 percent (mid-2008); energy peaked +29.3 percent (mid-2008, oil $147). Both elevated together. Resolution: financial crisis collapsed oil, Michigan inflation expectations crashed. Both deflationary by 2009.
2010-2014 normalization: food 1-3 percent typical; energy -5 to +15 percent typical (volatile). Modest divergence.
2014-2016 oil collapse: food 0-2 percent; energy -20 to -25 percent. Energy deflationary while food modest.
2020 COVID: food +5 percent (March 2020 panic buying); energy -22 percent (oil collapse). Food spike + energy collapse.
2021-2023 inflation surge: food peaked +11.4 percent (August 2022); energy peaked +41.6 percent (June 2022). Both elevated, energy more.
2024-2025 normalization: food 2-3 percent; energy -2 to +5 percent. Stable.
2026 Iran war: food 2.7 percent stable; energy +12.5 percent (March 2026). Energy surge specific.
The pattern: food and energy diverge during specific shocks (2008, 2014-2016, 2020, 2026). Both elevated during commodity supercycles (2007-2008, 2021-2022). Watch food for energy transmission lag 60-180 days.
How the Pair Performs in Stress
Stress history.
1973-74 oil crisis: food peaked +20 percent; energy peaked +40 percent. Both extreme.
2008 commodity peak: food +6.4 percent (mid-2008); energy +29.3 percent (mid-2008, oil $147). Crisis collapsed oil, both deflationary by 2009.
2014-2016 oil collapse: energy -20 to -25 percent; food 0-2 percent. Divergent (energy collapse, food stable).
2020 COVID flash crash: food +5 percent (March 2020 panic buying); energy -22 percent (oil collapse). Most extreme divergence.
2021-2022 inflation surge: food peaked +11.4 percent (Aug 2022); energy peaked +41.6 percent (June 2022). Both at multi-decade highs.
2023-2024 disinflation: food 2-3 percent; energy -2 to +5 percent. Both moderating.
2026 Iran war: food 2.7 percent stable; energy +12.5 percent (March 2026); gasoline +18.9 percent YoY. Iran war oil shock.
The pattern: severe stress produces extreme moves in both (1973-74, 2007-2008, 2021-2022). Specific shocks produce divergence (2014-2016 oil collapse, 2020 COVID, 2026 Iran). Pair captures shock attribution: shared shocks vs idiosyncratic.
Volatility and Trading
Food and energy CPI not directly tradable but components are. Energy exposure: USO (oil ETF), XLE (energy sector), gasoline ETFs (UGA), natural gas ETFs (UNG). Food exposure: agricultural commodities through DBA (Invesco DB Agriculture), individual commodities (corn ETF CORN, wheat ETF WEAT, soybean ETF SOYB), food sector stocks (XLP staples, MDLZ, KO, PG).
For positioning around CPI releases: strong energy CPI surprise (above consensus): long XLE, short XLY (consumer discretionary hurt by gas spike), short CMG/MCD (margin pressure). Weak energy: opposite. Strong food CPI surprise: long DBA, long XLP, food retailers (KR, ACI). Weak food: opposite.
CPI releases monthly (mid-month). Both food and energy components reported. Drivers attention to specific subcomponents (gasoline, food at home, food away from home).
The practical implication: monitoring food and energy CPI sub-components provides cleaner read on consumer experience than aggregate food/energy. Iran war oil shock dominant April 2026 driver.
Reading the Pair as a Trading Tool
For macro allocators, food-vs-energy CPI provides commodity inflation regime classification.
Both surge: commodity supercycle regime. Long DBA, USO, XLE; short XLY, growth equities. Inflation hedges work.
Energy surge + food stable (current April 2026): Iran war oil shock specific. Long USO, XLE; food stable. Watch food transmission lag 60-180 days.
Food surge + energy stable: agricultural commodity shock (drought, disease). Long DBA; energy stable.
Both fall: commodity collapse regime. Short USO, XLE; long XLY (consumer benefit from gas decline). Disinflation positioning.
Food < energy moderate (typical): mid-cycle stable. Both components moderate. Selective positioning.
April 2026 setup: food 2.7 percent + energy 12.5 percent. Energy surge + food stable regime. Long XLE benefits. Watch April-July 2026 food CPI for transmission lag impact.
Key watches: April 2026 CPI release (mid-May for April data); Iran ceasefire stability; oil price trajectory (WTI direction); agricultural commodity prices; weather patterns (drought, planting season).
How the Pair Compares to Other Inflation Indicators
Food-vs-energy captures non-core volatile components. Compared to other inflation indicators.
Vs CPI vs core CPI: headline (3.3 percent April 2026) vs core (2.6 percent). Captures broader inflation. Food + energy = headline minus core gap.
Vs energy CPI vs WTI: WTI $95.85 (April 2026); energy CPI +12.5 percent YoY. Direct relationship. WTI leads energy CPI by 30-60 days.
Vs food CPI vs grain prices: grain prices (corn, wheat, soybeans) lead food CPI 60-180 days.
Vs core CPI vs supercore: services components excluding shelter. Different focus.
Vs PPI food/energy vs CPI food/energy: PPI captures producer-level food/energy. Leads CPI by 1-2 months at producer level.
For allocator monitoring, food-vs-energy CPI captures the consumer-experienced volatile inflation components. April 2026 reading: food 2.7 percent + energy 12.5 percent (energy surge regime). Pair complements core CPI/PCE (Fed-watched), shelter/core (largest core component), CPI/PPI (supply chain), Michigan/breakeven (expectations) for comprehensive inflation cycle read.
Forward View: Watch Iran Ceasefire and Food Transmission
March 2026 food index +2.7 percent YoY (stable, near long-run average 2.5 percent); energy index +12.5 percent YoY; gasoline +18.9 percent YoY (March 2025 base). Food unchanged MoM March 2026; energy +10.9 percent MoM (gasoline +21.2 percent MoM). WTI $95.85 (April 2026, +30 percent from January 2026).
Forward-looking through 2026: April 2026 CPI release (mid-May) for April data. Three scenarios.
Base case: Iran ceasefire stabilizes. Oil moderates to $80-85. Energy CPI moderates to +5-8 percent YoY by Q3 2026. Food CPI rises modestly to 3.0-3.3 percent YoY (transportation cost transmission). Headline CPI moderates to 2.5-3.0 percent YoY.
Upside scenario: Iran tensions escalate. Oil rises to $110+. Energy CPI surges to +20-25 percent YoY. Food CPI rises to 3.5-4.0 percent YoY. Headline CPI surges to 4-5 percent YoY.
Downside scenario: Iran ceasefire complete + oil collapses. Energy CPI falls to 0 percent YoY. Food CPI falls to 2 percent YoY. Headline CPI falls to 2 percent YoY (Fed target reached).
Key watches: April 2026 CPI release (mid-May); Iran developments; oil prices; agricultural commodity prices; weather patterns; tariff developments.
Expected food +2.5 to +3.5 percent YoY range; energy +5 to +20 percent YoY range over coming 6 months.

Frequently Asked Questions
What are food CPI and energy CPI?+
Food CPI (FRED CPIUFDSL) and Energy CPI (FRED CPIENGSL) are the two non-core components of CPI excluded from core inflation due to volatility. March 2026 BLS release (April 10 2026): food index unchanged MoM, +2.7% YoY (stable trajectory); energy index +10.9% MoM (gasoline +21.2% MoM accounting for ~75% of monthly all-items increase); energy +12.5% YoY; gasoline prices +18.9% YoY (March 2026 vs March 2025); food away from home +0.2% MoM; food at home -0.2% MoM. Food + energy = 21% of CPI weight (food 13.5% + energy 7%). Headline CPI 3.3% YoY; core CPI 2.6% YoY (April 2026 readings).
Why are food and energy excluded from core?+
Volatility. Energy CPI volatility (YoY change) typically 15-30% annualized; food 2-5%; core CPI 0.5-1.5%. Food + energy 21% of CPI weight (food 13.5%, energy 7%). Core captures broader 79% with smoother behavior. Fed policy uses core because: (1) less affected by supply shocks (oil disruptions); (2) captures persistent pressures; (3) more responsive to monetary policy. For consumer experience, headline inflation (incl food/energy) drives sentiment. Michigan Consumer Sentiment 49.8 April 2026 (all-time low) reflects gasoline spike directly. Inflation expectations Michigan year-ahead 4.7% heavily influenced by gas prices. Food/energy matter politically + consumer behavior even if Fed focuses on core.
What is the 2026 Iran war energy shock?+
February 2026 Iran war catalyzed energy price surge. WTI rose $73 (January 2026) to $95.85 (April 2026, +30%). Energy CPI components affected: gasoline +21.2% MoM March (~75% of monthly all-items rise); fuel oil similar; natural gas less affected (US production cushioned); electricity minimal direct impact (5-year average lag). Energy CPI passthrough lags: transportation services 30-90 days; food at home 60-180 days for transportation costs; food away from home 90-180 days for restaurant menu adjustments; goods CPI 60-120 days for shipping cost passthrough. April 2026 surge has not yet transmitted to broader CPI. Watch May-September 2026 CPI releases.
What drives food CPI?+
Components: food at home (~58% of food CPI): meat/poultry/fish (16%), cereals/bakery (12%), dairy (12%), fruits/vegetables (12%), other (6%). Food away from home (~42%): restaurants. Key drivers: agricultural commodity prices (corn, wheat, soybeans, livestock - affected by weather, disease, trade policy); wage costs (restaurant wage inflation, food processing labor); transportation costs (fuel, shipping, rail); tariff impacts (import food prices for fruits/vegetables, seafood). April 2026 food CPI 2.7% YoY near long-run average 2.5%. Stable trajectory reflects: commodity moderation post-2022 surge, wage growth normalization, supply chain normalization. Iran war energy spike has not yet transmitted to food CPI.
How do food and energy CPI diverge?+
Typically diverge more than converge due to different drivers. Energy surge + food stable (current April 2026): supply shock to oil/gas without food impact. Watch transmission lag. Food surge + energy stable: agricultural commodity shock (drought, disease). Less common. Both surge: broader commodity supercycle (2007-2008, 2021-2022). Both fall: commodity collapse (2009, 2014-2016, 2020 COVID). Long-run correlation 0.30-0.55 (modestly positive). Strengthens during commodity supercycles. April 2026: food +2.7% + energy +12.5% (energy/food ratio 4.6x extreme). Iran war oil shock specific to energy with food temporarily insulated. Mean reversion likely.
How does the pair perform through cycles?+
2007-2008 commodity supercycle: food peaked +6.4% (mid-2008); energy peaked +29.3% (mid-2008, oil $147). Both elevated. 2010-2014 normalization: food 1-3%; energy -5 to +15%. 2014-2016 oil collapse: food 0-2%; energy -20 to -25%. 2020 COVID: food +5% (March 2020 panic buying); energy -22% (oil collapse). 2021-2023 inflation surge: food +11.4% peak (Aug 2022); energy +41.6% peak (June 2022). 2024-2025 normalization: food 2-3%; energy -2 to +5%. 2026 Iran war: food 2.7% stable; energy +12.5%. Pattern: diverge during specific shocks; both elevated during commodity supercycles. Watch food for energy transmission lag 60-180 days.
How is the pair traded?+
Components tradable through ETFs. Energy: USO (oil ETF), XLE (energy sector), gasoline ETFs (UGA), natural gas (UNG). Food: agricultural commodities through DBA (Invesco DB Agriculture), individual commodities (corn ETF CORN, wheat ETF WEAT, soybean ETF SOYB), food sector stocks (XLP staples, MDLZ, KO, PG). Strong energy CPI surprise: long XLE, short XLY (consumer discretionary hurt by gas), short CMG/MCD (margin pressure). Weak energy: opposite. Strong food: long DBA, XLP, food retailers (KR, ACI). Monitoring food + energy sub-components provides cleaner read on consumer experience. Iran war oil shock dominant April 2026 driver.
How is the pair used for trading?+
Both surge: commodity supercycle regime. Long DBA, USO, XLE; short XLY, growth equities. Inflation hedges work. Energy surge + food stable (current April 2026): Iran war oil shock specific. Long USO, XLE; food stable. Watch food transmission lag 60-180 days. Food surge + energy stable: agricultural commodity shock. Long DBA; energy stable. Both fall: commodity collapse regime. Short USO, XLE; long XLY (consumer benefit). Disinflation positioning. Food < energy moderate (typical): mid-cycle stable. April 2026 setup: food 2.7% + energy 12.5%. Energy surge + food stable regime. Long XLE benefits. Watch April-July 2026 food CPI for transmission impact.
