Rising oil prices – winners and losers

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.

Time to address global warming

In December 2015, countries from around the world met in Paris at the United Nations Intergovernmental Panel on Climate Change (IPCC). The key element of the resulting Paris Agreement was to keep ‘global temperature rise this century well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius.’ At the same time it was agreed that the IPCC would conduct an analysis of what would need to be done to limit global warming to 1.5°C. The IPPC has just published its report.

The report, based on more than 6000 scientific studies, has been compiled by more than 80 of the world’s top climate scientists. It states that, with no additional action to mitigate climate change beyond that committed in the Paris Agreement, global temperatures are likely to rise to the 1.5°C point somewhere between 2030 and 2040 and then continue rising above that, reaching 3°C by the end of the century.

According to the report, the effects we are already seeing will accelerate. Sea levels will rise as land ice caps and glaciers melt, threatening low lying coastal areas; droughts and floods will become more severe; hurricanes and cyclones will become stronger; the habits of many animals will become degraded and species will become extinct; more coral reefs will die and fish species disappear; more land will become uninhabitable; more displacement and migration will take place, leading to political tensions and worse.

Two tragedies



 
The problem of greenhouse gas emissions and global warming is a classic case of the tragedy of the commons. This is where people overuse common resources, such as open grazing land, fishing grounds, or, in this case, the atmosphere as a dump for emissions. They do so because there is little, if any, direct short-term cost to themselves. Instead, the bulk of the cost is borne by others – especially in the future.

There is another related tragedy, which has been dubbed the ‘tragedy of incumbents’. This is a political problem where people in power want to retain that power and do so by appealing to short-term selfish interests. The Trump administration lauds the use of energy as helping to drive the US economy and make people better off. To paraphrase Donald Trump ‘Climate change may be happening, but, hey, let’s not beat ourselves up about it and wear hair shirts. What we do will have little or no effect compared with what’s happening in China and India. The USA is much better off with a strong automobile, oil and power sector.’

What’s to be done?

According to the IPCC report, if warming is not to exceed 1.5℃, greenhouse gas emissions must be reduced by 45% by 2030 and by 100% by around 2050. But is this achievable?

The commitments made in the Paris Agreement will not be nearly enough to achieve these reductions. There needs to be a massive movement away from fossil fuels, with between 70% and 85% of global electricity production being from renewables by 2050. There needs to be huge investment in green technology for power generation, transport and industrial production.

In addition, the report recommends investing in atmospheric carbon extraction technologies. Other policies to reduce carbon include massive reforestation.

Both these types of policies involve governments taking action, whether through increased carbon taxes on either producers or consumer or both, or through increased subsidies for renewables and other alternatives, or through the use of cap and trade with emissions allocations (either given by government or sold at auction) and carbon trading, or through the use of regulation to prohibit or limit behaviour that leads to emissions. The issue, of course, is whether governments have the will to do anything. Some governments do, but with the election of populist leaders, such as President Trump in the USA, and probably Jair Bolsonaro in Brazil, and with sceptical governments in other countries, such as Australia, this puts even more onus on other governments.

Another avenue is a change in people’s attitudes, which may be influenced by education, governments, pressure groups, news media, etc. For example, if people could be persuaded to eat less meat, drive less (for example, by taking public transport, walking, cycling, car sharing or living nearer to their work), go on fewer holidays, heat their houses less, move to smaller homes, install better insulation, etc., these would all reduce greenhouse gas emissions.

Finally, there is the hope that the market may provide part of the solution. The cost of generating electricity from renewables is coming down and is becoming increasingly competitive with electricity generated from fossil fuels. Electric cars are coming down in price as battery technology develops; also, battery capacity is increasing and recharging is becoming quicker, helping encourage the switch from petrol and diesel cars to electric and hybrid cars. At the same time, various industrial processes are becoming more fuel efficient. But these developments, although helpful, will not be enough to achieve the 1.5°C target on their own.

USMCA or NAFTA 2.0?

An agreement in principle was reached on September 30 between the USA, Canada and Mexico over a new trade deal to replace the North American Free Trade Agreement (NAFTA). President Trump had described NAFTA as ‘the worst trade deal maybe ever signed anywhere, but certainly ever signed in this country.’ The new deal, named the United States-Mexico-Canada Agreement, or USMCA, is the result of 14 months of negotiations, which have often been fractious. A provisional bilateral agreement was made between the USA and Mexico in August. At the same time, President Trump threatened a trade war with Canada if it did not reach a trade agreement with the USA (and Mexico). The new USMCA must be ratified by lawmakers in all three countries before it can come into force. This could take a few months.

So is USMCA a radical departure from NAFTA? Does the USA stand to gain substantially, as President Trump claims? In fact, USMCA is little different from NAFTA. It could best be described as a relatively modest reworking of NAFTA. So what are the changes?

The first change affects the car industry. From 2020, 75% of the components of any vehicle crossing between the USA and Canada or Mexico must be made within one or more of the three countries to qualify for tariff-free treatment. The aim is to boost production within the region. But the main change here is merely an increase in the proportion from the current 62.5%.

A more significant change affecting the car industry concerns wages. Between 40% and 45% of a vehicle’s components must be made by workers earning at least US$16 per hour. This is some three times more than the average wage currently earned by Mexican car workers. Although it will benefit such workers, it will reduce Mexico’s competitive advantage and could hence lead to some diversion of production away from Mexico. Also, it could push up the price of cars.

The agreement has also strengthened various standards inadequately covered in NAFTA. According to The Conversation article:

The new agreement includes stronger protections for patents and trademarks in areas such as biotech, financial services and domain names – all of which have advanced considerably over the past quarter century. It also contains new provisions governing the expansion of digital trade and investment in innovative products and services.
 
Separately, negotiators agreed to update labor and environmental standards, which were not central to the 1994 accord and are now typical in modern trade agreements. Examples include enforcing a minimum wage for autoworkers, stricter environmental standards for Mexican trucks and lots of new rules on fishing to protect marine life.

Another area where the USMCA agreement has made changes concerns trade in dairy products. This particularly affects Canada, which has agreed to allow more US dairy products tariff-free into Canada (see the CNN article at the end of the list of articles below). New higher quotas will give US dairy farmers access to 3.6% of Canada’s dairy market. They will still pay tariffs on dairy exports to Canada that exceed the quotas, ranging from 200% to 300%.

The other significant change for consumers in Mexico and Canada is a rise in the value of duty-free imports they can bring in from the USA, including online transactions. As the first BBC article listed below states:

The new agreement raises duty-free shopping limits to $100 to enter Mexico and C$150 ($115) to enter Canada without facing import duties – well above the $50 previously allowed in Mexico and C$20 permitted by Canada. That’s good news for online shoppers in Mexico and Canada – as well as shipping firms and e-commerce companies, especially giants like Amazon.

Despite these changes, USMCA is very similar to NAFTA. It is still a preferential trade deal between the three countries, but certainly not a completely free trade deal – but nor was NAFTA.

And for the time being, US tariffs on Mexican and Canadian steel and aluminium imports remain in place. Perhaps, with the conclusion of the USMCA agreement, the Trump administration will now, as promised, consider lifting these tariffs.

Lehman Brothers: have we learned the lessons 10 years on?

Ten years ago, the financial crisis deepened and stock markets around the world plummeted. The trigger was the collapse of Lehman Brothers, the fourth-largest US investment bank. It filed for bankruptcy on September 15, 2008. This was not the first bank failure around that time. In 2007, Northern Rock in the UK (Aug/Sept 2007) had collapsed and so too had Bear Stearns in the USA (Mar 2008).

Initially there was some hope that the US government would bail out Lehmans. But when Congress rejected the Bank Bailout Bill on September 29, the US stock market fell sharply, with the Dow Jones falling by 7% the same day. This was mirrored in other countries: the FTSE 100 fell by 15%.

At the core of the problem was excessive lending by banks with too little capital. What is more, much of the capital was of poor quality. Many of the banks held securitised assets containing ‘sub-prime mortgage debt’. The assets, known as collateralised debt obligations (CDOs), were bundles of other assets, including mortgages. US homeowners had been lent money based on the assumption that their houses would increase in value. When house prices fell, homeowners were left in a position of negative equity – owing more than the value of their house. With many people forced to sell their houses, prices fell further. Mortgage debt held by banks could not be redeemed: it was ‘sub-prime’ or ‘toxic debt’.

Response to the crisis

The outcome of the financial crash was a series of bailouts of banks around the world. Banks cut back on lending and the world headed for a major recession.

Initially, the response of governments and central banks was to stimulate their economies through fiscal and monetary policies. Government spending was increased; taxes were cut; interest rates were cut to near zero. By 2010, the global economy seemed to be pulling out of recession.

However, the expansionary fiscal policy, plus the bailing out of banks, had led to large public-sector deficits and growing public-sector debt. Although a return of economic growth would help to increase revenues, many governments felt that the size of the public-sector deficits was too large to rely on economic growth.

As a result, many governments embarked on a period of austerity – tight fiscal policy, involving cutting government expenditure and raising taxes. Although this might slowly bring the deficit down, it slowed down growth and caused major hardships for people who relied on benefits and who saw their benefits cut. It also led to a cut in public services.

Expanding the economy was left to central banks, which kept monetary policy very loose. Rock-bottom interest rates were then accompanied by quantitative easing. This was the expansion of the money supply by central-bank purchases of assets, largely government bonds. A massive amount of extra liquidity was pumped into economies. But with confidence still low, much of this ended up in other asset purchases, such as stocks and shares, rather than being spent on goods and services. The effect was a limited stimulation of the economy, but a surge in stock market prices.

With wages rising slowly, or even falling in real terms, and with credit easy to obtain at record low interest rates, so consumer debt increased.

Lessons

So have the lessons of the financial crash been learned? Would we ever have a repeat of 2007–9?

On the positive side, financial regulators are more aware of the dangers of under capitalisation. Banks’ capital requirements have increased, overseen by the Bank for International Settlements. Under its Basel II and then Basel III regulations (see link below), banks are required to hold much more capital (‘capital buffers’). Some countries’ regulators (normally the central bank), depending on their specific conditions, exceed these the Basel requirements.

But substantial risks remain and many of the lessons have not been learnt from the financial crisis and its aftermath.

There has been a large expansion of household debt, fuelled by low interest rates. This constrains central banks’ ability to raise interest rates without causing financial distress to people with large debts. It also makes it more likely that there will be a Minsky moment, when a trigger, such as a trade war (e.g. between the USA and China), causes banks to curb lending and consumers to rein in debt. This can then lead to a fall in aggregate demand and a recession.

Total debt of the private and public sectors now amounts to $164 trillion, or 225% of world GDP – 12 percentage points higher than in 2009.

China poses a considerable risk, as well as being a driver of global growth. China has very high levels of consumer debt and many of its banks are undercapitalised. It has already experienced one stock market crash. From mid-June 2015, there was a three-week fall in share prices, knocking about 30% off their value. Previously the Chinese stock market had soared, with many people borrowing to buy shares. But this was a classic bubble, with share prices reflecting exuberance, not economic fundamentals.

Although Chinese government purchases of shares and tighter regulation helped to stabilise the market, it is possible that there may be another crash, especially if the trade war with the USA escalates even further. The Chinese stock market has already lost 20% of its value this year.

Then there is the problem with shadow banking. This is the provision of loans by non-bank financial institutions, such as insurance companies or hedge funds. As the International Business Times article linked below states:

A mind-boggling study from the US last year, for example, found that the market share of shadow banking in residential mortgages had rocketed from 15% in 2007 to 38% in 2015. This also represents a staggering 75% of all loans to low-income borrowers and risky borrowers. China’s shadow banking is another major concern, amounting to US$15 trillion, or about 130% of GDP. Meanwhile, fears are mounting that many shadow banks around the world are relaxing their underwriting standards.

Another issue is whether emerging markets can sustain their continued growth, or whether troubles in the more vulnerable emerging-market economies could trigger contagion across the more exposed parts of the developing world and possibly across the whole global economy. The recent crises in Turkey and Argentina may be a portent of this.

Then there is a risk of a cyber-attack by a rogue government or criminals on key financial insitutions, such as central banks or major international banks. Despite investing large amounts of money in cyber-security, financial institutions worry about their vulnerability to an attack.

Any of these triggers could cause a crisis of confidence, which, in turn, could lead to a fall in stock markets, a fall in aggregate demand and a recession.

Finally there is the question of the deep and prolonged crisis in capitalism itself – a crisis that manifests itself, not in a sudden recession, but in a long-term stagnation of the living standards of the poor and ‘just about managing’. Average real weekly earnings in many countries today are still below those in 2008, before the crash. In Great Britain, real weekly earnings in July 2018 were still some 6% lower than in early 2008.

Trump, the WTO and Brexit

Donald Trump has threatened to pull out of the World Trade Organization. ‘If they don’t shape up, I would withdraw from the WTO,’ he said. He argues that the USA is being treated very badly by the WTO and that the organisation needs to ‘change its ways’.

Historically, the USA has done relatively well compared with other countries in trade disputes brought to the WTO. However, President Trump does not like being bound by an international organisation which prohibits the unilateral imposition of tariffs that are not in direct retaliation against a trade violation by other countries. Such tariffs have been imposed by the Trump administration on steel and aluminium imports. This has led to retaliatory tariffs on US imports by the EU, China and Canada – something that is permitted under WTO rules.

Whether or not the USA does withdraw from the WTO, Trump’s threats bring into question the power of the WTO and other countries’ compliance with WTO rules. With the rise in protectionist sentiments around the world, the power of the WTO would seem to be on the wane.

Even if the USA does not withdraw from the WTO, it is succeeding in weakening the organisation. Appeals cases have to be heard by an ‘appellate body’, consisting of at least three judges drawn from a list of seven, each elected for four years. But the USA has the power to block new appointees – and has done so. As Larry Elliott states in the first article below:

The list of judges is already down to four and will be down to the minimum of three when the Mauritian member, Shree Baboo Chekitan Servansing, retires at the end of September. Two more members will go by the end of next year, at which point the appeals process will come to a halt.

This raises the question of the implication of a ‘no-deal’ Brexit – something that seems more likely as the UK struggles to reach a trade agreement with the EU. Leaving without a deal would mean ‘reverting to WTO rules’. But if these rules are being ignored by powerful countries such as the USA and possibly China, and if the appeals procedure has ground to a halt, this could leave the UK without the safety net of international trade rules. Outside the EU – the world’s most powerful trade bloc – the UK could find itself having to accept poor trade terms with the USA and other large countries.
