Oil prices are determined by demand and supply. Changes in oil prices are the result of shifts in demand and/or supply, with the size of the price change depending on the size of the shift and the price elasticity of demand and supply.

Some of the shifts are long term, with the price of oil varying from year to year or even moving in a particular direction for longer periods of time. Thus the opening up of new supplies, such as from fracking wells, can lead to a long-term fall in oil prices, while agreements by, say, OPEC to curb output can lead to a long-term rise in prices (see the blogs The oil see-saw, OPEC deal pushes up oil prices and An oil glut).

Medium and long-term price movements can also reflect medium and long-term changes in demand, such as a recession – oil prices fell dramatically as the world economy slid into recession in 2008/9 and then recovered as the global economy recovered.

Another long-term factor is the development of substitutes, such as renewable energy, which can reduce the demand for oil; another is developments that economise on power, such as more fuel-efficient vehicles and machines.

But oil prices do not just reflect these long-term movements in demand and supply. They also reflect daily and weekly movements as demand and supply respond to global and national events.

Two such events occurred at the end of August/beginning of September this year. The first was Hurricane Harvey. Even though it was downgraded to a tropical storm as it made landfall across the coast of the Gulf of Mexico, it dumped massive amounts of rain on southern Texas and Louisiana. This disrupted oil drilling and refining, shutting down a quarter of the entire US refining capacity. The initial effect was a surge in US oil prices in late August as oil production in much of Texas shut down and a rise in petrol prices as supplies from refineries fell.

Then prices fell back again in early September as production and refining resumed and as it became apparent that there had been less damage to oil infrastructure than initially feared. Also the USA tapped into some of its strategic oil reserves to make up for the shortfall in supply.

Then in early September, the North Koreans tested a hydrogen bomb – much larger than the previous atom bombs it had tested. This prompted fears of US retaliation and heightened tensions in the region. As the Reuters article states:

That put downward pressure on crude as traders moved money out of oil – seen as high-risk markets – into gold futures, traditionally viewed as a safe haven for investors. Spot gold prices rose for a third day, gaining 0.9 per cent on Monday

Quite large daily movements in oil prices are not uncommon as traders respond to such events. A major determinant of short-term demand is expectations, and nervousness about events can put substantial downward pressure on oil prices if it is felt that there could be a downward effect on the global economy – or substantial upward pressure if it is felt that supplies might be disrupted. Often markets over-correct, with prices moving back again as the situation becomes clearer and as nervousness subsides.

Ten years ago (on 9 August 2007), the French bank BNP Paribas sparked international concern when it admitted that it didn’t know what many of its investments in the US sub-prime property market were worth and froze three of its hedge funds. This kicked off the financial crisis and the beginning of the credit crunch.

In September 2007 there was a run on the Northern Rock bank in the UK, forcing the Bank of England to provide emergency funding. Northern Rock was eventually nationalised in February 2008. In July 2008, the US financial authorities had to provide emergency assistance to America’s two largest mortgage lenders, Fannie Mae and Freddie Mac.

Then in September 2008, the financial crisis really took hold. The US bank, Lehman Brothers, filed for bankruptcy, sending shock waves around the global economy. In the UK, Lloyds TSB announced that it was taking over the UK’s largest mortgage lender, Halifax Bank Of Scotland (HBOS), after a run on HBOS shares.

Later in the month, Fortis, the huge Belgian banking, finance and insurance company, was partly nationalised to prevent its bankruptcy. Also the UK government was forced to take control of mortgage-lender, Bradford & Bingley’s, mortgages and loans, with the rest of the business sold to Santander.

Early in October 2008, trading was suspended in the main Icelandic banks. Later in the month, the UK government announced a £37 billion rescue package for Royal Bank of Scotland (RBS), Lloyds TSB and HBOS. Then in November it partially nationalised RBS by taking a 58% share in the bank. Meanwhile various other rescue packages and emergency loans to the banking sector were taking place in other parts of the world. See here for a timeline of the financial crisis.

So, ten years on from the start of the crisis, have the lessons of the crisis been learnt. Could a similar crisis occur again?

The following articles look at this question and the answers are mixed.

On the positive side, banks are much more highly capitalised than they were ten years ago. Moves by the Basel Committee on Banking Supervision in its Basel III regulatory framework have ensured that banks are much more highly capitalised and operate with higher levels of liquidity. What is more, banks are generally more cautious about investing in highly complex and risky collateralised assets.

On the negative side, increased flexibility in labour markets, although helping to keep unemployment down, has allowed a huge squeeze on real wages as austerity measures have dampened the economy. What is more, household debt is rising to possibly unsustainable levels. Over the past year, unsecured debt (e.g. personal loans and credit card debt) have risen by 10% and yet (nominal) household incomes have risen by only 1.5%. While record low interest rates make such loans relatively affordable, when interest rates do eventually start to rise, this could put a huge strain on household finances. But if households start to rein in their borrowing, this would put downward pressure on aggregate demand and jeopardise economic growth.

Questions

  1. Explain what are meant by ‘collateralised debt obligations (CDOs)’.
  2. What part did CDOs play in the financial crisis of 2007–8?
  3. In what ways is the current financial situation similar to that in 2007–8?
  4. In what ways is it different?
  5. Explain the Basel III banking regulations.
  6. To what extent has the Bank of England exceeded the minimum Basel III requirements?
  7. Explain what is meant by ‘stress testing’ the banks? Does this ensure that there can never be a repeat of the financial crisis?
  8. Why is it desirable for central banks eventually to raise interest rates to a level of around 2–3%? Why might it be difficult for central banks to do that?

On the 15th June, the Bank of England’s Monetary Policy Committee decided to keep Bank Rate on hold at its record low of 0.25%. This was not a surprise – it was what commentators had expected. What was surprising, however, was the split in the MPC. Three of its current eight members voted to raise the rate.

At first sight, raising the rate might seem the obvious thing to do. CPI inflation is currently 2.9% – up from 2.7% in April and well above the target of 2% – and is forecast to go higher later this year. According to the Bank of England’s own forecasts, even at the 24-month horizon inflation is still likely to be a little above the 2% target.

Those who voted for an increase of 0.25 percentage points to 0.5% saw it as modest, signalling only a very gradual return to more ‘normal’ interest rates. However, the five who voted to keep the rate at 0.25% felt that it could dampen demand too much.

The key argument is that inflation is not of the demand-pull variety. Aggregate demand is subdued. Real wages are falling and hence consumer demand is likely to fall too. Thus many firms are cautious about investing, especially given the considerable uncertainties surrounding the nature of Brexit. The prime cause of the rise in inflation is the fall in sterling since the Brexit vote and the effect of higher import costs feeding through into retail prices. In other words, the inflation is of the cost-push variety. In such cirsumstances dampening demand further by raising interest rates would be seen by most economists as the wrong response. As the minutes of the MPC meeting state:

Attempting to offset fully the effect of weaker sterling on inflation would be achievable only at the cost of higher unemployment and, in all likelihood, even weaker income growth. For this reason, the MPC’s remit specifies that, in such exceptional circumstances, the Committee must balance any trade-off between the speed at which it intends to return inflation sustainably to the target and the support that monetary policy provides to jobs and activity.

The MPC recognises that the outlook is uncertain. It states that it stands ready to respond to circumstances as they change. If demand proves to be more resilient that it currently expects, it will raise Bank Rate. If not, it is likely to keep it on hold to continue providing a modest stimulus to the economy. However, it is unlikely to engage in further quantitative easing unless the economic outlook deteriorates markedly.

With the Conservatives having lost their majority in Parliament in the recent UK election, there is renewed discussion of the form that Brexit might take. EU states are members of the single market and the customs union. A ‘hard Brexit’ involves leaving both and this was the government’s stance prior to the election. But there is now talk of a softer Brexit, which might mean retaining membership of the single market and/or customs union.

The single market

Belonging to the single market means accepting the free movement of goods, services, capital and labour. It also involves tariff-free trade within the single market and adopting a common set of rules and regulations over trade, product standards, safety, packaging, etc., with disputes settled by the European Court of Justice. Membership of the single market involves paying budgetary contributions. Norway and Iceland are members of the single market.

The single market brings huge benefits from free trade with no administrative barriers from customs checks and paperwork. But it would probably prove impossible to negotiate remaining in the single market with an opt out on free movement of labour. Controlling immigration from EU countries was a key part of the Leave campaign.

The customs union

This involves all EU countries adopting the same tariffs (customs duties) on imports from outside the EU. These tariffs are negotiated by the European Commission with non-EU countries on a country-by-country basis. Goods imported from outside the EU are charged tariffs in the country of import and can then be sold freely around the EU with no further tariffs.

Remaining a member of the customs union would allow the UK to continue trading freely in the EU, subject to meeting various non-tariff regulations. It would also allow free ‘borderless’ trade between Northern Ireland and the Republic of Ireland. However, being a member of the customs union would prevent the UK from negotiating separate trade deals with non-EU countries. The ability to negotiate such deals has been argued to be one of the main benefits of leaving the EU.

Free(r) trade area

The UK could negotiate a trade deal with the EU. But it is highly unlikely that such a deal could be in place by March 2019, the date when the UK is scheduled to leave the EU. At that point, trade barriers would be imposed, including between the two parts of the island of Ireland. Such deals are very complex, especially in the area of services, which are the largest category of UK exports. Negotiating tariff-free or reduced-tariff trade is only a small part of the problem; the biggest part involves negotiating product standards, regulations and other non-tariff barriers.

All the above options thus involve serious problems and the government will be pushed from various sides, not least within the Conservative Party, for different degrees of ‘softness’ or ‘hardness’ of Brexit. What is more, the pressure from business for free trade with the EU is likely to grow. Brexit may mean Brexit, but just what form it will take is very unclear.

In the last blog post, As UK inflation rises, so real wages begin to fall, we showed how the rise in inflation following the Brexit vote is causing real wages in the UK to fall once more, after a few months of modest rises, which were largely due to very low price inflation. But how does this compare with other OECD countries?

In an article by Rui Costa and Stephen Machin from the LSE, the authors show how, from the start of the financial crisis in 2007 to 2015 (the latest year for which figures are available), real hourly wages fell further in the UK than in all the other 27 OECD countries, except Greece (see the chart below, which is Figure 5 from their article). Indeed, only in Greece, the UK and Portugal were real wages lower in 2015 than in 2007.

The authors examine a number of aspects of real wages in the UK, including the rise in self employment, differences by age and sex, and for different percentiles in the income distribution. They also look at how family incomes have suffered less than real wages, thanks to the tax and benefit system.

The authors also look at what the different political parties have been saying about the issues during their election campaigns and what they plan to do to address the problem of falling, or only slowly rising, real wages.
