After experiencing its sharpest price drop in the last couple of months, the cost of the basic food basket rose again in mid-June 2026, confirming that inflationary pressure in supermarkets continues to stifle household finances. Between 10 and 17 June, the set of 63 basic food items audited by the consumer protection association increased by €2.11 compared to the previous week, bringing the total bill to a significant €257.68.

The price escalation becomes even more evident when analysed from different temporal perspectives. Taking the start of this year as a reference, households are spending €15.86 more (an increase of 6.56%) to acquire exactly the same products. In a year-on-year comparison with the corresponding period of 2025, the additional cost amounts to €14.90, representing an increase of 6.14%. The gap reaches critical proportions when we look back to January 2022, the date when the organisation began this systematic data collection: in just over four years, the basket has increased by 37.28%, forcing citizens to spend an additional €69.98 per shopping trip.

In strictly weekly terms, the largest percentage increase was in cereal flakes, whose price jumped 18% to €2.83. The fish sector also exerted strong pressure, with mackerel registering a 16% increase in one week, reaching €6.25 per kilogram. Rounding out the products that increased the most in this short period, curly lettuce registered a 12% increase, now costing €2.63 per kilogram.

This same lettuce and mackerel are also highlighted when assessing market behaviour on an annual scale, confirming that fresh produce continues to drive the largest price increases compared to last year. In this year-on-year indicator, mackerel stands alone at the top with a 64% price increase, closely followed by Savoy cabbage, which rose by 40% to €1.78 per kilogram. Sea bass was another fish that experienced substantial inflation over 12 months, rising by 31% to €10.38 per kilogram, while curly lettuce consolidated an annual price increase of 25%.

In a long-term macro analysis starting in the first month of 2022, the scenario reveals profound structural changes in the costs of protein and vegetables. The most striking example is beef for stewing, which had the highest cumulative inflation during the period under analysis, registering a sharp 126% increase that pushed its average cost to €13.14 per kilogram. Meanwhile, eggs maintained a continuous upward trend, accumulating a historic increase of 84% and setting their current cost at around €2.10. Rounding out this trio of extraordinary increases since the start of DECO PROteste's monitoring is cabbage, whose current price reflects an accumulated growth of 79% compared to the values ​​practised just over four years ago.
