INE Snaps Industrial Producer Prices Back to +3.8% in April After Five Months in the Red — Energy Drives the Reversal at +17.2% While the Underlying IPPI Holds Tame at +1.4%

The Instituto Nacional de Estatística (INE) on Tuesday 19 May 2026 published its Industrial Producer Price Index (IPPI) for April 2026, snapping a five-month run of negative or zero readings with a year-on-year jump of 3.8% — the index's sharpest upward swing since late 2022. The headline number flips from 0.0% in March, and the entire reversal is structurally located in the energy grouping, which booked a 17.2% year-on-year jump. Strip out energy and the IPPI sits at just +1.4%, a hair above March's +0.1% ex-energy print.

The release is anchored in INE Destaque 770619173 and lands in the same statistical cycle that already carried the PRR ninth-payment update. Input-cost pipelines are turning back up after a quiet winter, but the underlying read in goods other than fuel and electricity is still well-behaved.

What the April reading shows

• Headline IPPI (year-on-year): +3.8% in April 2026, against 0.0% in March and -1.9% across Q1.
• Energy grouping: +17.2% year-on-year — the single line driving the reversal. Contrast: energy printed -9.6% across Q1 and was -18.8% as recently as February.
• IPPI excluding energy: +1.4% in April, up from +0.1% in March.
• Month-on-month: +2.4% versus -1.4% in April 2025 — a 3.8-point base effect that mechanically widens the year-on-year read.

Reading the energy line

The 17.2% year-on-year energy print is principally a base-effect story rather than a fresh fuel-price shock. April 2025 was the trough month last year — gas and wholesale electricity fell sharply through mid-spring 2025 — so the comparison base for April 2026 is much lower than the rolling Q1 base, mechanically flipping the year-on-year sign. The 1.4% IPPI ex-energy read is the more important policy number: it tells the Banco de Portugal and the ECB that domestic pipeline inflation outside the fuel chain is not re-accelerating. That is consistent with the April CPI INE published earlier this month, where the headline climbed to 3.3% mainly on fuels while underlying inflation sat at 2.2%.

What this means for expats and residents

• Fuel and electricity bills: Producer-price inflation in the energy line typically arrives at the consumer in the next 30-60 days. Expect liberalised-market electricity tariffs and fuel pumps to feel the pressure first; regulated-market tariffs reset less frequently.
• Household goods prices: The 1.4% ex-energy read suggests pipeline pressure on white goods, processed food and durables will stay limited near term — second-round effects from last year's energy shock have largely worked through.
• Wages versus prices: INE's parallel Q1 labour-cost release booked real gross monthly earnings up 2.7% — comfortably ahead of the April CPI read. Households should still be netting positive real-wage growth in May.
• Business buyers: Procurement budgets indexed to ex-energy IPPI will need only modest top-ups; energy-heavy contracts (logistics, cold-chain, manufacturing) will see sharper re-pricing in the next billing cycle.
• Budget read-across: The April reversal pushes nominal GDP higher and feeds the Conta Geral do Estado's revenue tracking; Miranda Sarmento's working assumption that Portugal can hold a zero-balance fiscal outturn in 2026 looks more defensible with producer prices back in positive territory.

The next INE release in this series is the May 2026 IPPI on 18 June. If the ex-energy line stays close to 1.4% while the energy print rolls off as the base effect fades, the headline IPPI is likely to drift back toward the 1-2% zone by Q3. If, instead, ex-energy starts running higher, the Banco de Portugal will read the May print as the first credible signal that imported gas and electricity prices are seeping into goods inflation again.
