DECO Cabaz Alimentar Eases to €260.41 in the Week of 6-13 May After a Record €261.89 — Spiral Pasta, Nile Perch and Canned Tuna Drive the Weekly Rise While the YTD Bill Sits €18.58 Above January

The consumer-rights association DECO Proteste closed the week of 6-13 May 2026 with its 63-product cabaz alimentar at €260.41, a step down from the previous week's record of €261.89 but still €18.58 above the January baseline — a 7.68% year-to-date rise that DECO and the supermarket trade body APED both flag as the dominant pressure on household budgets ahead of the May trimestral inflation read. The basket's weekly movements continue to be driven by a handful of categories — pasta, fish and pantry staples — whose individual price prints land far above the headline 1.9% Portuguese consumer-price-inflation rate.

What Moved in the Week

The largest weekly increases inside the 6-13 May print landed on massa em espiral at €1.46 (+9% week-on-week), perca do Nilo at €12.99/kg (+7%) and atum em óleo enlatado at €2.27 (+6%). The basket's headline ease back from €261.89 to €260.41 came mostly from the fresh-produce slice — tomato cherry and savoy cabbage gave back part of the previous week's spike — while the dry-goods slice stayed firm. DECO's tracking covers the same 63 items in the same store formats across the six main retail chains, which gives the print a comparable run-rate against the January 2026 baseline of €241.83.

The Three-Year Picture

The longer arc remains the structural story. Since DECO opened the methodology in February 2022, the largest cumulative price moves on individual items have been beef-stew meat (carne de vaca para guisar) at +126% to €13.14/kg, savoy cabbage (repolho lombarda) at +97% to €1.95/kg, and eggs at +84% to €2.10 per dozen. Versus the same week last year, the largest twelve-month jumps were repolho lombarda (+40%), robalo at €10.47/kg (+36%) and tomate cherry (+32% at €3.11). The cabaz tracks shopping for a single-income household of four and is the dataset that the Bank of Portugal and the Conselho das Finanças Públicas both reference in their inflation distribution models.

The Retail-Trade Posture

The supermarket trade association APED warned at end-2025 that food-price moderation was structurally unlikely in 2026 given the run-up in energy, water and labour costs across the production chain. Continente, the country's largest grocer, signalled in December it would raise shelf prices through the year. Pingo Doce and Lidl Portugal have leaned heavily on private-label expansion to anchor the cheaper end of the basket, with private-label penetration at the two chains crossing 50% of revenue in the most recent disclosure cycle.

What This Means for Expats

Single-source comparator: the DECO cabaz at €260.41 is the cleanest weekly read on the at-the-till cost of feeding a family of four in Portugal and updates every Tuesday on decoproteste.pt; it is the figure most expats use when calibrating Portuguese-vs-origin grocery budgets.
Private label as anchor: Continente Equação, Pingo Doce, Lidl's Milbona and Auchan's brands carry roughly 25-40% price discounts to comparable brand-label items in the same store; switching to private label cuts a typical basket by €30-40 a week.
Wage benchmark: the €260.41 weekly basket runs against a national minimum wage of €870 a month in 2026 — the basket alone is roughly 30% of the minimum-wage pay-packet.
What happens next: the next INE quarterly inflation print lands later in May. The trajectory in DECO's weekly basket is the leading indicator that the central forecasters at the BdP and the OECD watch ahead of that release.
