While inflation is a concern in the UK and is making the Bank of England think twice about keeping interest rates at their all time low of 0.5%, inflation in Japan is being celebrated. The Japanese economy has been plagued by deflation for over a decade and for the past 2 years inflation has never been above 0%. However, in April the consumer price index (CPI) rose to 0.6% from the previous year, fuelled by petrol prices. Strangely it might be the Japanese earthquake and tsunami that helped this situation, as Japan was unable to generate sufficient electricity and hence had to import fuel from abroad.

A typical question from non-economists is always about why deflation and hence falling prices is such a bad thing. Surely, it’s great for consumers? For those shopping for bargains, perhaps it is helpful – after all, if prices fall, a consumer’s real income will be higher. However, the problem with falling prices is that people start to hold off buying. If you want to buy a car, but expect prices to be lower next month, then it’s a rational decision to delay your purchase until next month when prices are lower. However, next month, you still expect prices to be lower in the following month and so delay purchasing again. And so the process continues. When people expect prices to fall they put off their purchases, this reduces demand and so prices do indeed fall. There are also costs for businesses: as consumers delay buying, sales begin to fall. And businesses are also consumers, and so they start delaying their purchases of inputs.

While many central banks across the world have begun to tighten monetary policy, the Japanese central bank seems inclined to keep monetary policy loose and has even considered expanding the emergency lending programme. As Azusa Kato, an economist at BNP Paribas, said:

“The bank will probably add stimulus if it sees more signs of weakening demand”. “If you strip out energy and food costs, consumer prices are basically flat now.”

Despite this inflationary pressure, many believe that it is unlikely to continue and deflationary pressures may appear once again in the near future. The following articles consider the Japanese deflationary situation.

Questions

  1. What are the main costs of deflation? Think about the wider effects on consumers, businesses and the government.
  2. What has caused the increase in inflation to 0.6% in Japan and why was there an expectation that inflation would re-appear?
  3. What explanation can be given for the belief that deflation will soon re-emerge?
  4. Using a demand and supply diagram, explain the process by which consumers delaying their consumption will lead to prices falling continuously.
  5. What is the best policy for the Japanese central bank to pursue in light of the new data?

Growth figures across many countries still remain vulnerable, including the UK, where growth lies at only 0.5%. Despite some countries starting to grow more rapidly, the numbers still remain close to 0. The eurozone area is a particularly interesting case, as there are so many individual countries that are all interdependent. So, despite growth in the eurozone area increasing to 0.8% in the first three months of 2011, which is higher than that for the UK, this doesn’t explain the full story in the area. Germany has grown by 1.5% and it is this figure which has largely contributed to the 0.8% figure. It was also helped by growth of 1% in France and incredibly of 0.8% in Greece, despite its huge debts. The growth in Greece is allegedly down to a better export market.

Why then wasn’t the figure higher? Whilst countries like Germany showed an acceleration in demand, growth remained sluggish in Spain and Italy at only 0.1% and 0.3% respectively and Portugal faced the second consecutive quarter of negative growth and so has officially gone back into recession. This situation may get even worse as the austerity measures put in place by the EU and IMF take effect. One of the key arguments against joining the eurozone is that the policies implemented are never going to be in the best interests of any one country. With some countries beginning to grow more quickly and others remaining sluggish, what should happen to macroeconomic policy? Should interest rates remain low in a bid to boost aggregate demand or should they rise as other countries see accelerating growth?

An interesting question here is why do countries, such as Italy, Spain and Portugal struggle, whilst France and Germany begin their recovery? One obvious explanation is that Germany and France are at the heart of the eurozone, where as Spain, Portugal and Italy remain on the periphery. Ken Wattret at BNP Paribas said:

“The periphery are getting the worst of both worlds. The core countries like Germany are doing really well and that’s keeping the euro strong, and it’s making the ECB [European Central Bank] more inclined to tighten policy.”

If the ECB do go ahead with a tightening of monetary policy, it could spell further trouble for those countries on the periphery of the Euro area that would benefit from interest rates remaining low and a weaker Euro. The following articles look at the conflicts within the 2-speed Eurozone.

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.

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.”

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.

  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?
