INE Pins May 2026 CPI at 3.3% for Second Straight Month — Core Inflation Holds 2.2% as Energy Reaccelerates to 13.1% and Unprocessed Food Cools to 5.7%

The Instituto Nacional de Estatística (INE) confirmed on 12 June 2026 that headline consumer-price inflation held steady at 3.3% year-on-year in May, marking a second consecutive month at the same reading and matching the statistics office's preliminary flash estimate. The Harmonised Index of Consumer Prices (IHPC) — the Eurostat-compatible benchmark used for cross-border comparison — moved the other way, slipping to 3.1% from 3.3% in April and settling 0.1 percentage points below the eurozone average.

The release lands two days after Banco de Portugal Governor Álvaro Santos Pereira pitched a tighter mortgage taxa de esforço cap and one day after the European Central Bank delivered its first rate hike since 2023, leaving Portuguese price dynamics squarely in the middle of the eurozone's mid-cycle disinflation debate.

What the May print tells us

Month-on-month, prices nudged 0.2% higher between April and May, a sharp deceleration from the 1.3% jump posted in April and a touch below the 0.4% reading recorded in the same May window of 2025. The 12-month average inflation rate — the smoothed metric typically referenced in salary negotiations and rental-update formulas — ticked up to 2.5%, one tenth above the prior 12-month average.

Underlying inflation, calculated by stripping out the volatile energy and unprocessed-food components, sat at 2.2% for the second consecutive month — a sign that domestic price pressures are no longer accelerating but have not yet rolled back into the European Central Bank's 2% medium-term target.

Energy back in the driver's seat

The single most striking line in the INE release is the renewed lift in energy products, where the annual rate of change accelerated to 13.1% from 11.7% in April. The reading reflects the carry-through from the partial unwinding of the IVA and ISP tax breaks that the previous government layered into the 2024 retail-fuel framework, combined with a step-up in regulated electricity tariffs at the start of the second quarter. The Hormuz-premium overhang that pushed Galp futures higher across the first ten days of June — captured separately in the Banco de Portugal daily activity tape — has not yet shown up in the May print, suggesting June numbers could come in hotter still.

Unprocessed food, which dominated the inflation conversation through the spring, decelerated meaningfully — to 5.7% from 7.4% in April. The category remains the single largest contributor to the headline number, but the slowdown matches the loosening seen in olive-oil, fresh fish and meat sub-indices captured in the Banco de Portugal weekly food-pricing tracker.

Sectoral splits and the eurozone gap

Inside the major COICOP buckets, transport prices accelerated to 6.0% year-on-year from 4.8% in April — the largest single category move in the release — driven by the same fuel-pricing dynamic feeding the energy bucket. Restaurants and accommodation slowed to 5.1% from 5.7%, the second consecutive deceleration as the post-Easter wave subsided. Clothing and footwear made one of the largest negative contributions, in line with the typical late-spring seasonal pattern as winter inventory clears.

The eurozone gap is the more interesting story for cross-border investors. Portugal's IHPC at 3.1% now runs below the bloc's flash estimate — and the core IHPC reading of 2.1% sits 0.2 percentage points beneath the eurozone aggregate of 2.3%. That gap, modest in headline terms, gives Frankfurt a marginal reason to keep the Portuguese leg of the curve in mind as the ECB pivots from its first June hike toward the September meeting.

How the May print stacks against forecasts

The OECD's June Economic Outlook, released last week, pencilled a 3.2% inflation peak for Portugal across the 2026 calendar year, with deceleration into the back half of 2027. The May reading keeps the trajectory comfortably below that ceiling for now, but the energy reacceleration to 13.1% is the single line item most likely to trip the OECD forecast if Brent stays anchored above the $75 mark through the third quarter.

What This Means for Expats

• Grocery basket cooling, not collapsed: Unprocessed food decelerated to 5.7%, meaning the worst of the supermarket-aisle pain looks to be in the rearview mirror — but the absolute level is still nearly triple the ECB's medium-term target. Household-budget assumptions built on 2024 grocery numbers should be refreshed.
• Energy bills climbing again: The 13.1% YoY reading on energy products means electricity, natural gas and bottled-LPG are the line items most likely to surprise to the upside on the next bill cycle. Households on variable-tariff EDP or Galp contracts should be alert for the Q3 readjustment.
• Mortgage carry math shifting: The ECB's first hike since 2023 has already pushed six-month Euribor to a fresh short-cycle high. Combined with sticky 2.2% core inflation, expats refinancing variable-rate Portuguese mortgages should pencil in higher monthly payments through year-end.
• Restaurant pricing easing: The slowdown to 5.1% in restaurants and accommodation means menu inflation is no longer outpacing wages quite as aggressively, but the cumulative two-year price level remains well above pre-2024 norms. Pad weekly dining budgets accordingly.
• Rental-contract anchor: The 12-month average of 2.5% is the figure typically referenced in private-sector salary negotiations and in the annual coeficiente de atualização that INE publishes around October. Tenants on five-year arrendamento contracts should expect their next update to print near that level.

What comes next

The June print, scheduled for release in early July, will be the first to capture any second-round effects from the partial restoration of fuel taxes and from the ECB's 25-basis-point deposit-facility hike. The Banco de Portugal's next Boletim Económico, due late July, is expected to refresh the 2026 inflation projection to reflect both the May print and the OECD's June numbers. With Eurostat's flash eurozone aggregate sitting at 3.2% and Portugal's IHPC running a tenth below, the country's inflation story is converging — finally — with the rest of the bloc.
