Tag: supply and demand

The global battle for fuel is expected to peak this winter. The combination of rising demand and a tightening of supply has sparked concerns of shortages in the market. Some people are worried about another ‘winter of discontent’. Gas prices have risen fivefold in Europe as a whole.

In the UK, consumers are likely to find that the natural gas needed to heat their homes this October will cost at least five times more than it did a year ago. This surge in wholesale gas prices has seen several UK energy suppliers stop trading as they are unable to make a profit. This is because of an energy price cap for some consumers and various fixed price deals they had signed with their customers.

There are thus fears of an energy crisis in the UK, especially if there is a cold winter. There are even warnings that during a cold snap, gas supply to various energy-intensive firms may be cut off. This comes at a time when some of these industries are struggling to make a profit.

Demand and supply

The current situation is a combination of long- and short-term factors. In spring 2020, the demand for gas actually decreased due to the pandemic. This resulted in low gas prices, reduced UK production and delayed maintenance work and investment along global supply chains. However, since early 2021, consumer demand for gas has soared. First, there was an increased demand due to the Artic weather conditions last winter. This was then followed by heatwaves in the USA and Europe over the summer, which saw an increase in the use of air conditioning units. With the increased demand combined with calm weather conditions, wind turbines couldn’t supply enough power to meet demand.

There has also been a longer-term impact on demand throughout the industry due to the move to cleaner energy. The transitioning to wind and solar has seen a medium-term increase in the demand for gas. There is also a long-term impact of the target for net zero economies in the UK and Europe. This has hindered investors’ willingness to invest in developing supplies of fossil fuels due the fact they could become obsolete over the next few decades.

Nations have also been unable to build up enough supplies for winter. This is partly due to Europe’s domestic gas stocks having declined by 30% per cent in the past decade. This heightened situation is leading to concerns that there will be black-outs or cut-offs in gas this winter.

Importation of gas

A concern for the UK is that it has scant storage facilities with no long-term storage. The UK currently has very modest amounts of storage – less than 6% of annual demand and some five times less than the average in the rest of Europe. It has been increasingly operating a ‘just-in-time model’, which is more affected by short-term price fluctuations in the wholesale gas market. With wind power generation remaining lower than average during summer 2021, more gas than usual has been used to generate electricity, leaving less gas to go into storage.

However, some argue that the problem is not just the UK’s physical supply of gas but demand for gas from elsewhere. Around half of the UK’s supply comes from its own production sites, while the rest is piped in from Europe or shipped in as liquefied natural gas (LNG) from the USA, Qatar and Russia. In 2019, the UK imported almost 20% of its gas through LNG shipments. However, Asian gas demand has grown rapidly, expanding by 50% over the past decade. This has meant that LNG has now become much harder to secure.

The issue is the price the UK has to pay to continue receiving these supplies. Some in the gas industry believe the price surge is only temporary, caused by economic disruptions, while many others say it highlights a structural weakness in a continent that has become too reliant on imported gas. It can be argued that the gas crisis has highlighted the lack of a coherent strategy to manage the gas industry as the UK transitions to a net zero economy. The lack of any industry investment in new capacity suggests that there is currently no business case for new long-term storage in the UK, especially as gas demand is expected to continue falling over the longer term.

Impact on consumers and industry

Gas prices for suppliers have increased fivefold over the past year. Therefore, many companies face a considerable rise in their bills. MSome may need to reduce or pause production – or even cease trading – which could cause job losses. Alternatively, they could pass on their increased costs to customers by charging them higher prices. Although energy-intensive industries are particularly exposed, every company that has to pay energy bills will be affected. Due to the growing concerns about the security of winter gas supplies those industries reliant on gas, such as the fertiliser industry, are restricting production, threatening various supply chains.

Most big domestic gas suppliers buy their gas months in advance, meaning they will most likely pass on the higher price rises they have experienced in the past few months. The increased demand and decreased supply has already meant meant that customers have faced higher prices for their energy. The UK has been badly hit because it’s one of Europe’s biggest users of natural gas – 85% of homes use gas central heating – and it also generates a third of the country’s electricity.

The rising bills are particularly an issue for those customers on a variable tariff. About 15 million households have seen their energy bills rise by 12% since the beginning of October due to the rise in the government’s energy price cap calculated by the regulator, Ofgem. A major concern is that this increase in bills comes at a time when the need to use more heating and lighting is approaching. It also coincides with other price rises hitting family budgets and the withdrawal of COVID support schemes.

Government intervention – maximum pricing

If the government feels that the equilibrium price in a particular market is too high, it can intervene in the market and set a maximum price. When the government intervenes in this way, it sets a price ceiling on certain basic goods or services and does not permit the price to go above that set limit. A maximum price is normally set for reasons of fairness and to benefit consumers on low incomes. Examples include energy price caps to order to control fuel bills, rent controls in order to improve affordability of housing, a cap on mobile roaming charges within the EU and price capping for regional monopoly water companies.

The energy price cap

Even without the prospect of a colder than normal winter, bills are still increasing. October’s increase in the fuel cap means that many annual household fuel bills will rise by £135 or more. The price cap sets the maximum price that suppliers in England, Wales and Scotland can charge domestic customers on a standard, or default tariff. The cap has come under the spotlight owing to the crisis among suppliers, which has seen eleven firms fold, with more expected.

The regulator Ofgem sets a price cap for domestic energy twice a year. The latest level came into place on 1 October. It is a cap on the price of energy that suppliers can charge. The price cap is based on a broad estimate of how much it costs a supplier to provide gas and electricity services to a customer. The calculation is mainly made up of wholesale energy costs, network costs such as maintaining pipes and wires, policy costs including Government social and environmental schemes, operating costs such as billing and metering services and VAT. Therefore, suppliers can only pass on legitimate costs of supplying energy and cannot charge more than the level of the price cap, although they can charge less. A household’s total bill is still determined by how much gas and electricity is used.

  • Those on standard tariffs, with typical household levels of energy use, will see an increase of £139.
  • People with prepayment meters, with average energy use, will see an annual increase of £153.
  • Households on fixed tariffs will be unaffected. However, those coming to the end of a contract are automatically moved to a default tariff set at the new level.

Ordinarily, customers are able to shop around for cheaper deals, but currently, the high wholesale prices of gas means that cheaper deals are not available.

Despite the cap limiting how much providers can raise prices, the current increase is the biggest (and to the highest amount) since the cap was introduced in January 2019. As providers are scarcely making a profit on gas, there are concerns that a further increase in wholesale prices will cause more suppliers to be forced out of business. Ofgem said that the cap is likely to go up again in April, the next time it is reviewed.

Conclusion

The record prices being paid by suppliers and deficits in gas supply across the world have stoked fears that the energy crisis will get worse. It comes at a time when households are already facing rising bills, while some energy-intensive industries have started to slow production. This has started to dent optimism around the post-pandemic economic recovery.

Historically, UK governments have trusted market mechanisms to deliver UK gas security. However, consumers are having to pay the cost of such an approach. The price cap has meant the UK’s gas bills have until now been typically lower than the EU average. However, the rise in prices comes on top of other economic problems such as labour shortages and increasing food prices, adding up to an unwelcome rise in the cost of living.

In its latest Commodity Special Feature (pages 43 to 53 of the October 2020 World Economic Outlook), the IMF examines the future of oil and other commodity prices. With the collapse in oil demand during the early stages of the coronavirus pandemic, oil prices plummeted. Brent crude fell from around $60 per barrel in late January to below $20 in April.

However, oil prices then rose somewhat and have typically been between $40 and $45 per barrel since June 2020 – still more than 35% lower than at the beginning of the year (see chart below: click here for a PowerPoint). This rise was caused by a slight recovery in demand but largely by supply reductions. These were the result partly of limits agreed by OPEC+ (OPEC, Russia and some other non-OPEC oil producing countries) and partly of reduced drilling in the USA and the closure of many shale oil wells which the lower prices had made unprofitable.

The IMF considers the future for oil prices and concludes that prices will remain subdued. It forecasts that petroleum spot prices will average $47 per barrel in 2021, up only slightly from the $42 average it predicts for 2020.

On the supply side it predicts that ‘stronger oil production growth in several non-OPEC+ countries, a faster normalization of Libya’s oil production, and a breakdown of the OPEC+ agreement’ will push up supply and push down prices. Even if the OPEC+ agreement holds, the members are set to ease their production cut by nearly 25% at the start of 2021. This rise in supply will be offset to some extent by possibly ‘excessive cuts in oil and gas upstream investments and further bankruptcies in the energy sector’.

On the demand side, the speed of the recovery from the pandemic will be a major determinant. If the second wave is long-lasting and deep, with a vaccine available to all still some way off, oil demand could remain subdued for many months. This will be compounded by the accelerating shift to renewable energy and electric vehicles and by government policies to reduce CO2 emissions.

Back in October, we examined the rise in oil prices. We said that, ‘With Brent crude currently at around $85 per barrel, some commentators are predicting the price could reach $100. At the beginning of the year, the price was $67 per barrel; in June last year it was $44. In January 2016, it reached a low of $26.’ In that blog we looked at the causes on both the demand and supply sides of the oil market. On the demand side, the world economy had been growing relatively strongly. On the supply side there had been increasing constraints, such as sanctions on Iran, the turmoil in Venezuela and the failure of shale oil output to expand as much as had been anticipated.

But what a difference a few weeks can make!

Brent crude prices have fallen from $86 per barrel in early October to just over $50 by the end of the year – a fall of 41 per cent. (Click here for a PowerPoint of the chart.) Explanations can again be found on both the demand and supply sides.

On the demand side, global growth is falling and there is concern about a possible recession (see the blog: Is the USA heading for recession?). The Bloomberg article below reports that all three main agencies concerned with the oil market – the U.S. Energy Information Administration, the Paris-based International Energy Agency and OPEC – have trimmed their oil demand growth forecasts for 2019. With lower expected demand, oil companies are beginning to run down stocks and thus require to purchase less crude oil.

On the supply side, US shale output has grown rapidly in recent weeks and US output has now reached a record level of 11.7 million barrels per day (mbpd), up from 10.0 mbpd in January 2018, 8.8 mbpd in January 2017 and 5.4 mbpd in January 2010. The USA is now the world’s biggest oil producer, with Russia producing around 11.4 mpbd and Saudi Arabia around 11.1 mpbd.

Total world supply by the end of 2018 of around 102 mbpd is some 2.5 mbpd higher than expected at the beginning of 2018 and around 0.5 mbpd greater than consumption at current prices (the remainder going into storage).

So will oil prices continue to fall? Most analysts expect them to rise somewhat in the near future. Markets may have overcorrected to the gloomy news about global growth. On the supply side, global oil production fell in December by 0.53 mbpd. In addition OPEC and Russia have signed an accord to reduce their joint production by 1.2 mbpd starting this month (January). What is more, US sanctions on Iran have continued to curb its oil exports.

But whatever happens to global growth and oil production, the future price will continue to reflect demand and supply. The difficulty for forecasters is in predicting just what the levels of demand and supply will be in these uncertain times.

Oil prices have been rising in recent weeks. With Brent crude currently at around $85 per barrel, some commentators are predicting the price could reach $100. At the beginning of the year, the price was $67 per barrel; in June last year it was $44. In January 2016, it reached a low of $26. But what has caused the price to increase?

On the demand side, the world economy has been growing relatively strongly. Over the past three years, global growth has averaged 3.5%. This has helped to offset the effects of more energy efficient technologies and the gradual shift away from oil to alternative sources of energy.

On the supply side, there have been growing constraints.

The predicted resurgence of shale oil production, after falls in both output and investment when oil prices were low in 2016, has failed to materialise as much as expected. The reason is that pipeline capacity is limited and there is very little scope for transporting more oil from the major US producing area – the Permian basin in West Texas and SE New Mexico. There are similar pipeline capacity constraints from Canadian shale fields. The problem is compounded by shortages of labour and various inputs.

But perhaps the most serious supply-side issue is the renewed sanctions on Iranian oil exports imposed by the Trump administration, due to come into force on 4 November. The USA is also putting pressure on other countries not to buy Iranian oil. Iran is the world’s third largest oil exporter.

Also, there has been continuing turmoil in the Venezuelan economy, where inflation is currently around 500 000 per cent and is expected to reach 1 million per cent by the end of the year. Consequently, the country’s oil output is down. Production has fallen by more than a third since 2016. Venezuela was the world’s third largest oil producer.

Winners and losers from high oil prices

The main gainers from high oil prices are the oil producing countries, such as Russia and Saudi Arabia. It will also encourage investment in oil exploration and new oil wells, and could help countries, such as Colombia, with potential that is considered underexploited. However, given that the main problem is a lack of supply, rather than a surge in demand, the gains will be more limited for those countries, such as the USA and Canada, suffering from supply constraints. Clearly there will be no gain for Iran.

In terms of losers, higher oil prices are likely to dampen global growth. If the oil price reaches $100 per barrel, global growth could be around 0.2 percentage points lower than had previously been forecast. In its latest World Economic Outlook, published on 8 October, the IMF has already downgraded its forecast growth for 2018 and 2019 to 3.7% from the 3.9% it forecast six months ago – and this forecast is based on the assumption that oil prices will be $69.38 a barrel in 2018 and $68.76 a barrel in 2019.

Clearly, the negative effect will be greater, the larger a country’s imports are as a percentage of its GDP. Countries that are particularly vulnerable to higher oil prices are the eurozone, Japan, China, India and most other Asian economies. Lower growth in these countries could have significant knock-on effects on other countries.

Consumers in advanced oil-importing countries would face higher fuel costs, accounting for an additional 0.3 per cent of household spending. Inflation could rise by as much as 1 percentage point.

The size of the effects depends on just how much oil prices rise and for how long. This depends on various demand- and supply-side factors, not least of which in the short term is speculation. Crucially, global political events, and especially US policies, will be the major driving factor in what happens.

Food prices often rise or fall with good or bad harvests or because of a change in demand. A recent example is the price of brazil nuts, which by May this year had risen over 60% on European markets.

Part of the reason for the price rise has been on the demand side. Consumption of brazil nuts has increased as more people switch to healthier diets. This includes the purchase of the nuts themselves and as part of healthier snack foods. With supply being relatively inelastic, any rise in demand tends to have a relatively large effect on price.

A more acute reason is on the supply side. There has been a very poor harvest of brazil nuts. The nuts are grown largely in the Amazon basin which has been hit by drought linked to the El Niño effect. This, however, is only a temporary effect and future harvests should increase again as rainfall returns to normal. However, in the longer term, rainfall patterns may change with the effects of global warming.

The price rise in the UK has also be aggravated by the depreciation of the pound since the Brexit vote, which has fallen some 13% against the dollar since June 2016. A rise in the dollar price of brazil nuts has thus led to an even bigger rise in their sterling price.
