There's no real debate about the fact that bananas and milk both taste good and are generally a healthy option in our diet. But these modern-day food staples also have in common a much less savoury side. And the murky economics of 21st century banana retailing might be doing us all disfavour in the long run.
British supermarkets - and in particular the in-vogue Aldi and Lidl discounters - use both bananas and milk as huge loss leaders. And in the process are driving all but the biggest producers of both out of business.
“To industry observers, bananas demonstrate how low European hard discount pioneers will go to secure their customers' loyalty,” says Alistair Smith, international coordinator of Banana Link.
“The banana business model they have adopted is uncompromising and the impacts of the strategy on people and the environment are very serious.”
Unions representing plantation and packhouse workers believe the hard discounters are using the fruit as a hook to get new customers through their doors at the expense of those who labour hard to produce it.
It seems that Aldi, followed by Lidl, play the competition rules in their home market closer to the letter than to the spirit of the law.
Banana prices fixed by Aldi on a quarterly basis (since 2011) are for fruit delivered to the ripener, but the transport costs from there on are not included in the company's retail price-setting calculations.
If they were to include transport costs to depots and on to their stores, then Aldi (and other supermarket chains that follow the same business model) would almost certainly fall foul of the German competition authorities for below-cost selling when they retail bananas at 79 or 85 euro cents per kilo.
In the UK supermarkets like Asda - and retailers who only offer Fairtrade-labelled bananas, like J Sainsbury - have been selling loose bananas at or below cost for several years, making up some or all of the 'sacrificed' margins on bagged fruit. Unlike in France or Germany, below-cost selling in the British market is not illegal.
“This allows the major retailers in the UK who, with the exception of The Co-operative Group, all sell loose bananas at or below cost to argue legitimately they are not breaking any law and it is their own sovereign decision to fund this near-permanent rock-bottom price,” claims Smith.
“And so, led by Aldi and Asda, the race to the bottom in the European banana market is fuelled by the belief that cheap bananas are what everybody needs or wants.”
Even more serious for those trying to construct a sustainable future for the industry is that all attempts to reverse this race in Europe's two biggest markets are frustrated.
Tesco, Sainsbury and Waitrose have all attempted to raise the loose banana retail price since the permanent price war set in four or more years ago in the UK.
“But every time the cynical Asda price-setters have sat it out - safe in the knowledge, from their point of view, that every kilo sold at £0.68 (0,87 euro at 5 January 2015 rates) hurts their competitors' margins more than it hurts their own,” says Smith.
And it seems that as long as customers prefer a ready-bagged 'Pack of 10' that costs £1.00 a kilo in Asda, there are still profits to be recouped.
Other banana retailing worlds do exist. In France, apart from the occasional short-lived price promotion at 0,89 or 0,99 cents/kilo, it seems major retailers have little or no appetite for systematically sacrificing their margins as hard discounters do in Germany and the UK.
Carrefour, Auchan, Leclerc or Intermarché are far from infringing national legislation that prohibits below-cost selling.
Banana retail margins in France are more substantial, with an average retail price across all outlets exceeding 1,50 euro/kilo. Typically, a kilo of loose bananas from the same supplier sold in the UK at £0.68 can be found at €1,49 in a French hypermarket. Loose bananas in smaller city centre outlets are usually €1,79 or €1,99.
Of course, none of this value generated at the retail end in France is systematically available for investment in producing countries; and the Fairtrade market share is very small compared to the UK, even though it is growing again for the first time in many years; Fairtrade loose bananas are non-existent.
In North American markets banana retail margins are more typically where they were in the UK before price wars became a permanent feature.
“Along with consumption retail prices have risen in the USA - bananas have always liked to confound conventional economic theory,” adds Smith.
As US retail pricing shows, a global giant like Asda/Walmart does not have a single global policy when it comes to pricing. “We are dealing with what the retailers call 'price-flexing', but at a planetary scale when it comes to Walmart,” explains Smith.
Bananas are, of course, not the only Known Value Item (KVI) that suffer from inter-retailer price wars in the UK. Milk, oranges, bread and pork pies are victims too, with producers and those they employ at home and abroad the ones who have to pay the not-so-hidden costs.
More worrying for the competitors of Aldi and Lidl is it seems bananas may be helping bring people through the doors of the hard discounters as consumer change their shopping habits.
Complexity lies behind such a simple statement and Aldi's banana retail prices per kilo for conventional bananas in the UK are even harder to work out than in other retailers.
First, the retailer does not deal in loose bananas (where prices per kilo are posted for customers to see). They sell packs of three in a plastic tray at £0.39, a seven 'Funsize' pack at £1.09, or Organic Fairtrade at £1.39 per kilo.
Second, however, a truth that is of great concern to their UK competitors is that Aldi and Lidl both sell more than double the volume of bananas than their overall food market share would indicate.
Intriguingly for banana-watchers, it seems this high banana volume is not based on price, especially as the Aldi per kilo retail price works out at well above the £0.68 the other major retailers espouse.
Aldi and Lidl are attracting increasingly 'up-market' customers away from the big four or five traditional retailers, in many cases through massive advertising campaigns. And thesenew consumers are not the traditional hard discount customers with whom the German discounters forged their entrance into the UK.
“The lack of visibility of a price per kilo reinforces the theory that, actually, the great majority of banana consumers do not look at the price; they just know they are cheap,” says Smith.
Tesco trades almost one banana in every 13 sold in the European Union, more than any other retailer. But its biggest single food-line is barely contributing to profits, as bananas do for almost all other retailers worldwide.
Now that almost all the bananas they sell are sourced directly from growers across six countries, with written multi-annual contracts to boot, the company is feeling the market heat.
In both the UK and Ireland Tesco is losing customers to hard discounters who buy their bananas cheaper and sell them at a higher price. Economics on its head - but ethics too.
So Europe's biggest banana seller has decided to differentiate itself through a responsible sourcing strategy, which is still in its infancy but which shows enormous promise.
In 2014, two inter-related commitments set the stage for a transformation of the European banana market that should be welcome news for all.
Last March, a public document called ‘Trading Responsibly’ committed Tesco to covering the costs of sustainable production in all their banana supply chains; for the time being they are using the Fairtrade ‘minimum price’, set by Fairtrade International, as the benchmark for a sustainable price to its suppliers.
Where this price was not attained in 2014, the difference in price to suppliers has been set aside whilst a mechanism to transfer the money to workers and their families is being designed.
Linked to that, in November, the company stated in a blog on its website that it will ensure that by 2017 living wages will be paid on all the banana plantations that grow and pack exclusively for Tesco (of which there are growing number spread across the four major Latin American exporting countries).
“A race to the top in the ethical content and the prices paid for bananas is now only being held back by the short-sighted strategies of a couple of other powerful multinational retailers,” says Smith.
A good rallying-point for all concerned is the third global conference of the World Banana Forum in the Dominican Republic at the end of June this year.
According to Kevin McCullough, head of campaigns at the Fairtrade Foundation, loose bananas bought in the UK today are so cheap that around three in four banana workers in countries that supply UK supermarkets live below the poverty line.
"Over the last 10 years, the retail price of loose bananas has halved while the cost of producing them has doubled - and it is banana farmers and workers in the developing world that pay the price, with many trapped in an unrelenting cycle of poverty,” he said.
"Retailers including Sainsbury’s, Waitrose and The Co-operative sell 100 percent Fairtrade bananas, which means they can provide an independent assurance that banana farmers and workers are not suffering as a result of low prices for shoppers.
"Recent research for the Fairtrade Foundation’s ‘Make Bananas Fair’ campaign found that more than eight in ten UK consumers are willing to pay more for their bananas, if the farmers and workers who produced them benefit.
"Instead of being shocked by the price of bagged bananas over loose ones we should be ensuring that banana farmers and workers aren’t being asked to pay the price for our cheap fruit."
