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.

Questions

  1. Why did commodity prices fall so dramatically in early May, only to rise again rapidly afterwards?
  2. Why do commodity prices fluctuate more than house prices?
  3. What is the relevance of price elasticity of demand and supply in explaining the volatility of commodity prices?
  4. Under what circumstances is speculation likely to be (a) stabilising; (b) destabilising?

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?

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?

In January 2011, Chinese growth accelerated to 9.8% as industrial production and retails sales picked up. As the second largest economy, this very high growth is hardly surprising, but it has caused concern for another key macroeconomic variable: inflation. Figures show that inflation climbed to 5.2% in March from a year before and the billionaire investor George Soros has said it is ‘somewhat out of control’. High property and food prices have contributed to high and rising inflation and this has led to the government implementing tightening measures within the economy.

In March, growth in property prices did finally begin to slow, according to the survey by the National Bureau of Statistics. Prices of new built homes had risen in 49 out of 70 Chinese cities in March from the previous months, but this was down from 56 cities in February. A property tax has also been implemented in cities like Shanghai and the minimum down payment required for second-home buyers has risen in a bid to prevent speculative buying. Bank reserve requirements have also been increased for the fourth time, after an increase in the interest rate at the beginning of April. The required reserve ratio for China’s biggest banks has now risen to 20.5%.

The situation in China is not the only country causing concern. Inflation in emerging markets is a growing concern, especially for the richer nations. The Singaporean finance minister, Tharman Shanmugaratnam, said:

“When inflation goes up in emerging markets, it’s not just an emerging market problem, it’s a global inflation and possibly interest rate problem … We have learned from painful experience in the past few years that nothing is isolated and that risk in one region rapidly gets transmitted to the rest of the world.”

He has said that inflation in emerging markets needs addressing to ensure that it does not begin to threaten the economic recovery of other leading economies. The following articles consider the latest Chinese developments.

  3. Why is there concern about high inflation in emerging markets and the impact it might have on other countries?
  4. How could the inflation in China hurt the economic recovery of countries such as the UK?
  5. How will the increase in the banks’ reserve requirements help inflation?
  6. Is high Chinese growth and high inflation the relationship you would expect to occur between these macroeconomic objectives? Explain your answer.

There’s been a lot of bad news about the economy, but perhaps things are looking up. Inflation is now at 4% and the latest data suggests that unemployment has fallen, with more jobs being created in the private sector. An estimated 143,000 jobs were created, many of which were full-time and the ILO measure if unemployment is down by some 17,000. There is still some doom and gloom, as growth in annual average earnings has fallen slightly and this will undoubtedly affect retail sales. Numbers claiming JSA have also increased marginally to 1.5 million and youth unemployment has seen a small increase to 20.4%. A big area of concern is that unemployment might rise in the coming months due to the time lag. Growth in the last quarter of 2010 was negative and this could increase unemployment when the full effects are felt in the labour market later in the year. Howard Archer, the Chief Economist at HIS Global Insight had this to say about the latest data.

‘Despite the overall firmer tone of the latest labour market data, we retain the view that unemployment is headed up over the coming months. We suspect that likely below-trend growth will mean that the private sector will be unable to fully compensate for the increasing job losses in the public sector that will result from the fiscal squeeze that is now really kicking in. Indeed, we believe that private sector companies will become increasingly careful in their employment plans in the face of a struggling economy and elevated input costs.’

The wage price spiral hasn’t begun as many though, and this may encourage the Bank of England to keep interest rates down, especially as inflation has come down to 4% and concerns about growth still remain. So despite good news about unemployment overall falling, young workers, women and public sector workers have not benefited. Youth unemployment is up, more women are claiming JSA and more jobs in the public sector are expected to be cut this year. The following articles consider the implications.
