Anyone investing in commodities over the past few weeks will have been in for a bumpy ride. During the first part of 2011, commodity prices have soared (see A perfect storm brewing?). This has fuelled inflation and has caused the Bank of England to revise upwards its forecast for inflation (see Busy doing nothing see also Prospects for Inflation).

But then in the first week of May, commodity prices plumetted. On the 5 May, oil prices fell by 7.9% – their largest daily amount since January 2009. Between 28 April and 6 May silver prices fell from $48.35 per ounce to just over $33.60 per ounce – a fall of over 30%. And it was the same with many other commodities – metals, minerals, agricultural raw materials and foodstuffs.

Many financial institutions, companies and individuals speculate in commodities, hoping to make money buy buying at a low price and selling at a high price. When successful, speculators can make large percentage gains in a short period of time. But they can also lose by getting their predictions wrong. In uncertain times, speculation can be destabilising, exaggerating price rises and falls as speculators ‘jump on the bandwagon’, seeing price changes as signifying a trend. In more stable times, speculation can even out price changes as speculators buy when prices are temporarily low and sell when they are temporarily high.

Times are uncertain at present. Confidence fluctuates over the strength of the world recovery. On days of good economic news, demand for commodities rises as people believe that a growing world economy will drive up the demand for commodities and hence their prices. On days of bad economic news, the price of commodities can fall. The point is that when undertainty is great, commodity prices can fluctuates wildly.

Despite better economic growth in the first quarter of 2011, confidence remains low and according to Halifax, this has contributed to a decline in house prices from March to April by 1.4% to give their lowest average price since July 2009. Halifax has blamed this steady decline on a lack of confidence and the uncertain economic climate. However, despite this latest decline, Halifax have suggested that the trend may be coming to an end. Martin Ellis, from Halifax had this to say:

“Signs of a modest tightening in housing market conditions, a relatively low burden of servicing mortgage debt and an increase in the number of people in employment are all likely to be providing support for house prices, curbing the pace of decline. There are signs that house sales are stabilising, albeit at a level lower than the historical average.”

There are many factors that contribute towards house prices: the number of properties on the market, the number of buyers, the availability of mortgages and finance, interest rates and the future economic climate. How these factors change will have a crucial influence on the future house price trend. The following articles consider the causes and likely consequences of this latest housing market data.

Questions

  1. What are the main causes behind this decline in house prices?
  2. The articles talk about the volatility of house prices over recent months. What is the explanation for this?
  3. If interest rates are increased by the MPC, is it more or less likely to cause house prices to decline further? Explain your answer.
  4. Why dies Martin Ellis, of Halifax, believe that the decline in house prices might reverse this year?
  5. How does the housing market affect the wider UK economy? Is these latest data likely to jeopardise the fragile recovery?

Just as the Bank of England has an inflation target of 2%, so does the ECB. UK inflation has been significantly above its target rate for many months and so has the eurozone’s inflation rate, which is up to 2.8% in April from its previous level of 2.7% the previous month. The increase in the general price level has been fuelled by rising costs of raw materials and high energy prices. Whilst interest rates in the UK have remained at 0.5% in a bid to stimulate economic growth, the ECB has increased interest rates by a quarter point to 1.25% and the latest inflation data may be further pressure for further rises. However, any increase in rates will put more pressure on countries such as Greece, Ireland and Portugal who are facing tough austerity measures and may put their recoveries in jeopardy.

The ECB has been optimistic about growth and it may need to be with this and possibly subsequent interest rate hikes, as they are likely to depress aggregate demand. Furthermore, European Commission’s ‘economic sentiment’ indicator has fallen to 106.2, which is the weakest since November. Eurozone unemployment remains at just under 10%, oil prices remain high and this has depressed optimism across the eurozone countries. The euro, meanwhile, continues to strengthen (up 12% against the dollar over the past year) and this has enhanced the fragile state of affairs in those countries suffering from tough austerity measures. An economist at ING has said:

“The combination of high oil prices, a strong euro, and fiscal and monetary tightening has started to dent the economic mood in the euro zone.”

Questions

  1. What is the relationship between interest rates and inflation. Why have the ECB and the Bank of England reacted differently to rising inflation?
  2. Is the inflation currently being experienced in the Eurozone cost-push or demand-pull? Illustrate your answer with the help of a diagram.
  3. What is the relationship between interest rates and the exchange rate?
  4. Why is there some concern about the ‘economic sentiment’ indicator in the Eurozone?
  5. What is the relationship between interest rates and economic growth? Explain the process by which a change in interest rates could affect AD and then economic growth and employment.
  6. Why is this interest rate rise (and possible further rises) likely to hurt countries, such as Ireland and Greece more than other countries within the Eurozone?

According to the first estimates by the Office for National Statistics, real UK GDP rose by 0.5% in the first quarter of 2011. In the House of Commons, David Cameron claimed that “it’s clearly a success the economy is growing”, while Ed Balls, Shadow Chancellor, countered this by stating that the economy “flat-lined in the last six months with no growth at all”.

So who is right? According to the statistics both are, in the sense that the economy grew by 0.5% in the first quarter of 2011 after shrinking by 0.5% in the fourth quarter of 2010. But what bigger picture do the figures paint? Is the economy now in recovery mode? Or is the fact that growth is so small a sign that the economy is still fragile? Could it easily dip back into recession as the tax increases and government expenditure cuts begin to bite?

And what of the policy implications? Do the latest figures make a rise in Bank Rate more or less likely in the near future? And how will the figures impact on confidence? Are they more or less likely to stimulate investment? Will consumers feel more confident that recovery is under way and their jobs are therefore more secure?

The following articles assess the situation and look ahead at the prospects for the UK economy.

In the past few weeks, the prices of gold and silver have been soaring and have hit all-time (nominal) highs. Over the past 12 months, gold has risen by 31%, while silver has risen by 149% and 64% since the start of February. Part of this reflects the general rise in commodity prices (see also). Oil is trading at around $125 per barrel, up 43% on a year ago; wheat is up 66%, maize by 114%, coffee (Arabica) by 118% and cotton by 122%.

Part of the reason for the rise in the price of precious metals, however, has been the weakness of the dollar. In such times, gold and silver are often seen as a ‘safe haven’ for investors.

So why have commodity prices been rising and why has the dollar been falling? What is likely to happen to the prices of gold and silver in the coming weeks and months? Is their meteoric rise set to continue? Will the ratio of the gold price to the silver price continue to fall? The following articles investigate.

Questions

  1. Why have the prices of gold and silver risen so much recently?
  2. Why has silver risen more than gold?
  3. Why may higher rates of world inflation make investors turn to precious metals for investment?
  4. How are future decisions by the Fed likely to affect the price of gold?
  5. According to the efficient capital markets theory (strong version), the current price of a commodity should already reflect all knowable factors that are likely to affect the price? Does this mean that speculative buying (or selling) is pointless?
  6. How is the price elasticity of supply of silver and gold relevant in explaining the magnitude of their price movements?
