Coffee highs

Coffee prices have been soaring in recent months. This applies to the prices of both coffee beans on international markets, coffee in supermarkets and coffee in coffee shops. In this blog we examine the causes and what is likely to happen over the coming months.

As we shall see, demand and supply analysis provides a powerful explanation of what has been happening in the various sectors of the industry and the likely future path of prices.

The coffee industry

The cultivating, processing and retailing of coffee is big business. It is the second most widely traded commodity after oil and around 2.5 billion cups are consumed worldwide on a daily basis. In the UK nearly 100 million cups of coffee a day are drunk, with coffee consumers spending around £4 billion per year on sit-down and takeaway coffees and on coffee bought in supermarkets and other shops for making at home. The average takeaway coffee costs around £3.40 per cup with speciality coffees costing more.

Global production in the coffee year 2023/24 was 178 million 60 kg bags (10.7 million tonnes) and the annual income of the whole sector exceeds $200 billion. Around 25 million farmers spread across 50 countries harvest coffee. The majority of these farms are small and family run. Some 100 million families worldwide depend on coffee for their living.

Brazil is by far the biggest producer and accounts for nearly 40% of the market. A good or poor harvest in Brazil can have a significant impact on prices. Vietnam and Columbia are the second and third biggest producers respectively and, with Brazil, account for over 60% of global production.

Coffee prices are extremely volatile – more so than production, which does, nevertheless, fluctuate with the harvest. Figure 1 shows global coffee production and prices since 1996. The price is the International Coffee Organization’s composite indicator price (I-CIP) in US cents per pound (lb). It is a weighted average of four prices: Colombian milds (Arabica), Other milds (Arabica), Brazilian naturals (mainly Arabica) and Robusta. Production is measured in 60 kilo bags.

Case Study 2.3 on the student website for Economics 11th edition, looks at the various events that caused the fluctuations in prices and supply illustrated in Figure 1 (click here for a PowerPoint). In this blog we focus on recent events.

Why are coffee prices rising?

In early October 2023, the ICO composite indicator price (I-CIP), was $1.46 per lb. By 28 August, it had reached $2.54 – a rise of 74%. Colombian milds (high-quality Arabica) had risen from $1.79 per lb to $2.78 – a rise of 55%. Robusta coffee is normally cheaper than Arabica. It is mainly used in instant coffee and for espressos. As the price of Arabica rose, so there was some substitution, with Robusta coffees being added to blends. But as this process took place, so the gap between the Arabica and Robusta prices narrowed. Robusta prices rose from $1.14 in early October 2023 to £2.36 in late August – a rise of 107%. These prices are illustrated in Figure 2 (click here for a PowerPoint).

This dramatic rise in prices is the result of a number of factors.

Supply-side factors.  The first is poor harvests, which will affect future supply. Frosts in Brazil have affected Arabica production. Also, droughts – partly the result of climate change – have affected harvests in major Robusta-producing countries, such as Vietnam and Indonesia. With the extra demand from the substitution for Arabica, this has pushed up Robusta prices as shown in Figure 2. Another supply-side issue concerns the increasingly vulnerability of coffee crops to diseases, such as coffee rust, and pests. Both reduce yields and quality.

As prices have risen, so this has led to speculative buying of coffee futures by hedge funds and coffee companies. This has driven up futures prices, which will then have a knock-on effect on spot (current) prices as roasters attempt to build coffee stocks to beat the higher prices.

There have also been supply-chain problems. Attacks on shipping by Houthi rebels in the Red Sea have forced ships to take the longer route around the Cape of Good Hope. Again, this has particularly affected the supply of Robusta, largely grown in Asia and East Africa.

New EU regulation banning the import of coffee grown in areas of cleared rainforest will further reduce supply when it comes into force in 2025, or at least divert it away from the EU – a major coffee-consuming region.

Demand-side factors.  On the demand side, the rise of the coffee culture and a switch in demand from tea to coffee has led to a steady growth in demand. Growth in the coffee culture has been particularly high in Asian markets as rapid urbanistion, a growing middle class and changing lifestyles drive greater coffee consumption and greater use of coffee shops. This has more than offset a slight decline in coffee shop sales in the USA. In the UK, the number of coffee shops has risen steadily. In 2023, there were 3000 cafés, coffee chains and other venues serving coffee, of which 9885 were branded coffee shop outlets, such as Costa, Caffè Nero and Starbucks. Sales in such coffee chains rose by 11.9% in 2023. Similar patterns can be observed in other countries, all helping to drive a rise in demand.

But although demand for coffee in coffee shops is growing, the rise in the price of coffee beans should have only a modest effect on the price of a cup of coffee. The cost of coffee beans purchased by a coffee shop accounts for only around 10% of the price of a cup. To take account of the costs to the supplier (roasting, distribution costs, overheads, etc), this price paid by the coffee shop/chain is some 5 times the cost of unroasted coffee beans on international markets. In other words, the international price of coffee beans accounts for only around 2% of the cost of a cup of coffee in a coffee shop.

Higher coffee-shop prices are thus mainly the result of other factors. These include roasting and other supplier costs, rising wages, rents, business rates, other ingredients such as milk and sugar, coffee machines, takeaway cups, heating, lighting, repairs and maintenance and profit. The high inflation over the past two years, with several of these costs being particularly affected, has been the major driver of price increases in coffee shops.

The future

The rise in demand and prices over the years has led to an increase in supply as more coffee bushes are planted. As Figure 1 shows, world supply increased from 87 million in 1995/6 to 178 million 60 kilo bags in 2023/4 – a rise of 105%. The current high prices may stimulate farmers to plant more. But as it can take four years for coffee plants to reach maturity, it may take time for supply to respond. Later on, a glut might even develop! This would be a case of the famous cobweb model (see Case Study 3.13 on the Essentials of Economics 9th edition student website).

Nevertheless, climate change is making coffee production more vulnerable and demand is likely to continue to outstrip supply. Much of the land currently used to produce Arabica will no longer be suitable in a couple of decades. New strains of bean may be developed that are more hardy, such as variants of the more robust Robusta beans. Whether this will allow supply to keep up with demand remains to be seen.

The UK’s national fixed broadband network – wasteful duplication or effective competition?

You may have recently noticed construction workers from different businesses digging up the roads/pavements near where you live. You may also have noticed them laying fibre optic cables. Why has this been happening? Does it make economic sense for different companies to dig up the same stretch of pavement and lay similar cables next to one another?

For many years the UK had one national fixed communication network that was owned by British Telecom (BT) – the traditional phone landline made from copper wire. This is now operated by OpenReach – part of the BT group but a legally separate division. In addition to this national infrastructure, Virgin Media (formed in 2007 from the merged cable operators, Telewest and NTL) has gradually built up a rival fixed broadband network that now covers just over 50 per cent of the country.

Although customers have only had very limited choice over which fixed communication network to use, they have had far greater choice over which Internet service provider (ISP) to sign up for. This has been possible as the industry regulator, Ofcom, forces OpenReach to provide rival ISPs such as Sky Broadband, TalkTalk and Zen with access to its network.

Expansion of the fibre optic network

Recent government policy has tried to encourage and incentivise the replacement of the copper wire network with one that is fully fibre. This is often referred to as Fibre to the Premises (FTTP) or Fibre to the Home (FTTH). A fixed network of fully fibre broadband enables much faster download speeds and many argue that it is vital for the future competitiveness of the UK economy.

Replacing the existing fixed communication network with fibre optic cables is expensive. It can involve major civil works: i.e. the digging up of roads and pavements to install new ducts to lay the fibre optic cables inside.

Over a hundred companies, that are not part of either OpenReach or Virgin Media O2 (the parent company of Virgin Media), have recently been digging up pavements/roads and laying new fibre optic cables. Known as alternative network providers (altnets) or independent networks, these businesses vary in size, with many of them securing large loans from banks and private investors. By the middle of 2023, 2.5 million premises in the UK had access to at least two or more of these independent networks.

After a slow initial response to the altnets, OpenReach has recently responded by rapidly installing FTTP. The business is currently building 62 000 connections every week and plans to have 25 million premises connected by the end of 2026. In July 2022, Virgin Media O2 announced that it was establishing a new joint venture with InfraVia Capital Partners. Called Nexfibre, this business aims to connect 5 million premises to FTTP by 2026.

Is the fibre optic network a natural monopoly?

Some people argue that the fixed communication network is an example of a natural monopoly – an industry where a single firm can supply the whole market at a lower average cost than two or more firms. To what extent is this true?

An industry is a natural monopoly where the minimum efficient scale of production (MES) is larger than the market demand for the good/service. This is more likely to occur where there are significant economies of scale. Digging up roads/pavements, installing new ducts and laying fibre optic cable are clear examples of fixed costs. Once the network is built, the marginal cost of supplying customers is relatively small. Therefore, this industry has significant economies of scale and a relatively large MES. This has led many people to argue that building rival fixed communication networks is wasteful duplication and will lead to higher costs and prices.

However, when judging if a sector is a natural monopoly, it is always important to remember that a comparison needs to be made between the MES and the size of the market. An industry could have significant economies of scale, but not be an example of a natural monopoly if the market demand is significantly larger than the MES.

In the case of the fixed communication network, the size of the market will vary significantly between different regions of the country. In densely populated urban areas, such as large towns and cities, the demand for services provided via these networks is likely to be relatively large. Therefore, the MES could be smaller than the size of the market, making competition between network suppliers both possible and desirable. For example, competition may incentivise firms to innovate, become more efficient and reduce costs.

Research undertaken for the government by the consultancy business, Frontier Economics, found that at least a third of UK households live in areas where competition between three or more different networks is economically desirable.

By contrast, in more sparsely populated rural areas, demand for the services provided by these networks will be smaller. The fixed costs per household of installing the network over longer distances will also be larger. Therefore, the MES is more likely to be greater than the size of the market.

The same research undertaken by Frontier Economics found that around 10 per cent of households live in areas where the fixed communication network is a natural monopoly. The demand and cost conditions for another 10 per cent of households meant it is not commercially viable to have any suppliers.

Therefore, policies towards the promotion of competition, regulation, and government support for the fixed communication network might have to be adjusted depending on the specific demand and cost conditions in a particular region.

Review

Questions

  1. Explain the difference between fixed and wireless communication networks.
  2. Draw a diagram to illustrate a profit-maximising natural monopoly. Outline some of the implications for allocative efficiency.
  3. Discuss some of the issues with regulating natural monopolies, paying particular attention to price regulation.
  4. The term ‘overbuild’ is often used to describe a situation where more than one fibre broadband network is being constructed in the same place. Some people argue that incumbent network suppliers deliberately choose to use this term to imply that the outcome is harmful for society. Discuss this argument.
  5. An important part of government policy in this sector has been the Duct and Pole Access Strategy (DPA). Illustrate the impact of this strategy on the average cost curve and the minimum efficient scale of production for fibre broadband networks.
  6. Draw a diagram to illustrate a region where (a) it is economically viable to have two or more fibre optic broadband network suppliers and (b) where it is commercially unviable to have any broadband network suppliers without government support.
  7. Some people argue that network competition provides strong incentives for firms to innovate, to become more efficient and reduce costs. Draw a diagram to illustrate this argument.
  8. Explain why many ‘altnets’ are so opposed to OpenReach’s new ‘Equinox 2’ pricing scheme for its fibre network.

Support for firms forced to close: guaranteeing revenue?

Some firms in the high-Covid, tier 3 areas in England are being forced to shut by the government. These include pubs and bars not serving substantial meals. Similarly, pubs in the central belt of Scotland must close. But how should such businesses and their employees be supported?

As we saw in the blog, The new UK Job Support Scheme: how much will it slow the rise in unemployment?, the government will support such businesses by paying two-thirds of each employees’ salary (up to a maximum of £2100 a month) and will give cash grants to the businesses of up to £3000 per month.

This support has been criticised by local leaders, such as those in Greater Manchester, as being insufficient. Workers, they argue, will struggle to pay their bills and the support for firms will be too little to prevent many closing for good. What is more, many firms and their employees in the supply chain, such as breweries, will get no support. Greater Manchester resisted being put into tier 3 unless the level of support was increased. However, tier 3 status was imposed on the authority on 20 October despite lack of agreement with local politicians on the level of support.

Jim O’Neill, Vice Chair of the Northern Powerhouse partnership, has argued that the simplest way of supporting firms forced to close is to guarantee their revenue. He stated that:

The government would be sensible to guarantee the revenues of businesses it is forcing to shut. It is easier, fairer and probably less costly in the long run – and a proper test of the government’s confidence that in the New Year two of the seven vaccines the UK has signed up to will work.

This would certainly help firms to survive and allow them to pay their employees. But would guaranteeing revenues mean that such firms would see an increase in profits? The questions below explore this issue.

Going nuclear

The UK government has finally given the go-ahead to build the new Hinkley C nuclear power station in Somerset. It will consist of two European pressurised reactors, a relatively new technology. No EPR plant has yet been completed, with the one in the most advanced stages of construction at Flamanville in France, having experienced many safety and construction problems. This is currently expected to be more than three times over budget and at least six years behind its original completion date of 2012.

The Hinkley C power station, first proposed in 2007, is currently estimated to cost £18 billion. This cost will be borne entirely by its builder, EDF, the French 85% state-owned company, and its Chinese partner, CGN. When up and running – currently estimated at 2025 – it is expected to produce around 7% of the UK’s electricity output.

On becoming Prime Minister in July 2016, Theresa May announced that the approval for the plant would be put on hold while further investigation of its costs, benefits, security concerns, technological issues and safeguards was conducted. This has now been completed and approval has been granted subject to new conditions. The main one is that the government “will be able to prevent the sale of EDF’s controlling stake prior to the completion of construction”. This will allow the government to prevent change of ownership during the construction phase. Thus, for example, EDF, would not be allowed to sell its share of Hinkley C to CGN, which currently has a one-third share in the project. EDF and CGN have accepted the new terms.

After Hinkley the government will have a ‘golden share’ in all future nuclear projects. “This will ensure that significant stakes cannot be sold without the Government’s knowledge or consent.”

In return for their full financing of the project, the government has guaranteed EDF and CGN a price of £92.50 per megawatt hour of electricity (in 2012 prices). This price will be borne by consumers. It will rise with inflation from now and over the first 35 years of the power station’s operation. It is expected that the Hinkley C will have a life of 60 years.

Critics point out that this guaranteed ‘strike price’ is more than double the current wholesale price of electricity and, with the price of renewables falling as technology improves, it will be an expensive way to meet the UK’s electricity needs and cut carbon emissions.

Those in favour argue that it is impossible to predict electricity prices into the distant future and that the certainty this plant will give is worth the high price by current standards.

To assess the desirability of the plant requires an assessment of its costs and benefits. In principle, this is a relatively simple process of identifying and measuring the costs and benefits, including external costs and benefits; discounting future costs and benefits to give them a present value; weighting them by their probability of occurrence; then calculating whether the net present value is positive or negative. A sensitivity analysis could also be conducted to show just how sensitive the net present value would be to changes in the value of specific costs or benefits.

In practice the process is far from simple – largely because of the huge uncertainty over specific costs and benefits. These include future wholesale electricity prices, unforeseen problems in construction and operation, and a range of political issues, such as pressure from various interest groups, and attitudes and actions of EDF and CGN and their respective governments, which will affect not only Hinkley C but other future power stations.

The articles look at the costs and benefits of this, the most expensive construction project ever in the UK, and possibly on Earth..

Sainsbury’s and Argos: Good or bad?

There has been a link between Sainsbury’s and Argos, with Sainsbury’s offering Argos concessions in some stores. But now, we’re looking at a much more significant link, with Sainsbury’s offering £1.3 billion for control of Home Retail Group’s Argos.

Many have questioned the sense of this offer, wondering what Sainsbury’s will gain from purchasing Argos, but Sainsbury’s has indicated it will boost sales, give itself access to a more advanced delivery network and Argos customers. Argos has worked hard to update its image, moving towards a more technology based catalogue and promising same day delivery in a bid to compete with companies, such as Amazon.

Online delivery is a costly business, with suggestions that retailers make losses on each delivery and hence pay customers to shop online. This move by Sainsbury’s may therefore be an investment in expanding its online delivery services and using the infrastructure that Argos already has. This will therefore help Sainsbury’s to invest in this sought after customer service, without having to invest millions into providing the infrastructure in the first place. This move may give Sainsbury’s a first mover advantage in the grocery sector, which may force other competitors to follow suit.

We could write for hours on the ins and outs of this potential deal and undoubtedly commentators will argue both for and against it. The following articles consider the good and bad sides and the future of grocery retailers in the UK.
