We recently had spikes in some products such as olive oil, among others. Right now the most notable price spike is for eggs, mainly due to the bird flu. However it is common for news to show farmers arguing that they are being squeezed by large supermarkets to keep their profits low and whatnot with a statement of theirs being that they prefer to let the crops rot or have them thrown away rather than operate at lower profits or even have a loss for that specific period of time.
With the olive oil for instance, extra virgen olive oil to be specific, price per litre was quite steady between 2013 and 2021, around 2.8€/L, sometimes a bit higher and sometimes a bit lower but it was around that price. Last year on January 2024 it reached its peak at 8.7€/L, with supermarkets selling it at 12.9€/L. Now prices are back to what's considered normal, below 5€/L.
However at the end of last month the Government announced they will be moving to short production by up to 20% if the yields from crops are too good this season.
I remember this also happening with potatoes and onions in 2017 where farmers preferred to destroy the crops rather than operate at a loss.
