In the context of targeted monthly research by the Consumer Retail Research Research Institute (IELKA) exclusively on the large supermarket chains on inflationary trends in organized food retailer, the prices are examined in September 20.
The following conclusions came from the survey:
Inflation in supermarket chains is in the order of +0.61% in September 2025 compared to September 2024, with a tendency to decline at lower levels compared to the previous 4 months.
It is noted in addition that the prices of September 2025 compared to the previous month of August 2025 are reduced by -0.76%.
In total, the rolling of 12 months (October 2024-September 2025) records +0.76%.
Higher price reductions in September 2025 compared to September 2024 are recorded in the categories:
• Fresh fruits and vegetables: -5.63%
• detergents and cleaning items: -5.40%
• Grocery Foods: -5.18%
• Foods & Types for Pets: -3.21%
• disposable items, household items: -3.18%
The reductions recorded are the result of both the normalization of the market and the reduction in producer prices in certain products. Larger reductions are recorded in fresh fruits and vegetables (the decrease comes from the category of vegetables which has been favored lately by weather), detergents and cleaning supplies, and grocery stores (due to the declining price of olive oil).
Larger increases in September 2025 compared to September 2024 are recorded in the categories:
• Fresh meats: +10.18%
• Biscuits, chocolates, sugar: +9.88%
• Breakfast species & drinks: +6.06%
• Dairy and refrigerator juices: +4.26%
• frozen: +3.82%
In relation to increases in fresh meats, this is a development due to increases in international prices in imported species and especially to the calf due to the decrease in animal capital (it is noted that the majority of calf and pork consumed in Greece are imported in Greece) and secondly in Greece).
As shown in Figure 2, on week 38 of 2025 (August 15-21) the producer price of the meat for a young male animal in the European Union has increased by 35.4% compared to the same week in 2024 and 23.5% compared to the beginning of 2025, while the trend remains growing.
The international prices of cocoa and coffee certainly affect the categories of sweets, both breakfast and drinks, but also frozen (eg ice creams, sweets). In relation to cocoa price, increases in raw material prices internationally over the last 2 years due to climate conditions were very high. In June 2025, 168.9% are recorded compared to the same month in 2023.
Compared to the same month in 2024 the prices are relatively close, but in previous months prices have reached $ 10,710 per tonne, at the same time prices have not yet stabilized. It is noted that due to the nature of cocoa products, by -products (chocolate) and finished products (sweets) are produced in subsequent years at different prices.
The reasons to which the tendency of broader product prices are attributed to supermarkets:
• Inflation Defense. Prices have been restrained in the last eighteen months in large grocery stores due to large volumes of products that are moving, economies of scale, their organizational-technological readiness and private label products.
• High traffic speed. Price retaining appears much faster in large points of sale due to higher stock speeds. That is, they move their stock faster and soon make new markets to replenish stocks.
• Influence of private label products. Private label sales shares are larger in large supermarket chains due to a widest range of code, and over the last two years they have been increasing.
