The latest data from the just-food international basket, published today, covers the first quarter of 2012. The basket is a group of 17 items from tuna to milk that will highlight the difference in price between national brands and own label in seven international markets. Amid the worst economic conditions for a generation, shoppers are becoming more promiscuous in their behaviour and the data will prove valuable to brand manufacturers, own-label suppliers and retailers alike.

The basket price in each of the markets monitored, apart from in Greece, where retailers reacted to the severe austerity in the country.

If the just-food basket contained only national brands, Dutch consumers would have seen the biggest price increase year-on-year in the first quarter of 2012. If it comprised only own-label, consumers in the UK would have experienced the biggest jump.

Greece and Spain have been where the price gap between brands and private label is growing, reflecting the economic pressure being felt there. In every other country, the gap has been shrinking as retailers invest to create greater value-add in the range they offer, fighting head to head with national brands.

Promotional intensity has levelled and even declined in five of the seven major economies with only the Netherlands and Germany seeing growth.
