Interest rates are the main tool of monetary policy and have a history of being an effective tool in creating macroeconomic stability. There has been much discussion since the end of the financial crisis concerning when interest rates would rise in the US (and the UK) and for the US, the case is stronger, given its rate of growth, which has averaged at 2.2% per annum since June 2009.
As in the UK, the question of ‘will rates rise?’ has a clear and certain answer: Yes. The more challenging question is ‘when?’. Much of the macroeconomic data for the US is promising, with positive economic growth (and relatively strong in comparison to the UK and Eurozone), a low unemployment rate and inflation of 0.3%. This last figure is ‘too low’, but it comes in at a much more attractive 1.2% if you exclude food and energy costs and there is an argument for doing this, given the price of oil. The data on unemployment and growth might suggest that the economy is at a stage where a rate rise could be managed, but the inflation data indicates that low interest rates might be needed to keep inflation above 0%. Furthermore, there are concerns that the low unemployment figure is somewhat misleading, given that under-employment is quite high at 10.3% and there are still many who are long-term unemployed, having been out of work for more than 6 months.

Interest rates can be a powerful tool in affecting the components of aggregate demand (AD) and hence the macroeconomic variables. If interest rates fall, it can help to stimulate AD by reducing borrowing costs for consumers and businesses, reducing the incentive to save, cutting variable rate mortgage payments and depreciating the exchange rate. Collectively these effects can stimulate an economy and hence create economic growth, reduce unemployment and push up prices. However, interest rates have been at almost 0% since the financial crisis, so the only way is up. Reversing the aforementioned effects could then spell trouble, if the economy is not in a sufficiently strong position.
For many, the strength of the US economy, while relatively good, is not yet good enough to justify a rate rise. It may harm investment, growth and unemployment and none of these variables are sufficiently high to warrant a rate rise, especially given the slowdown in the emerging markets. Karishma Vaswani, from BBC News said:
“The current global hand-wringing and head-holding over whether the US Fed will or won’t raise interest rates later has got investors here in Asia worried about what this means for their economies.
The Fed has become the favourite whipping boy of Asia’s central bankers, with cries from India to Indonesia to “just get on with it”.”
There are many, including Professor John Taylor from Stanford University and a former senior Treasury official, a rate rise is well over-due. The market is expecting one and has been for some time and these expectations aren’t going away, so ‘just get on with it.’ Janet Yellen, the Chair of the Federal Reserve is in a tricky situation. She knows that whatever is decided, markets around the world will react – no pressure then! The following articles consider the interest rate debate.

The UK’s balance on trade continues to be sharply in deficit. At the same time, both manufacturing and overall production are still well below their pre-crisis levels. What is more, with a sterling exchange rate that has appreciated substantially over recent months, UK exports are at an increasing price disadvantage. The hoped-for re-balancing of the economy from debt-financed consumption to investment and exports has not occurred. Investment in the UK remains low relative to that in other major economies (see).
But other developments in the global economy are working in the UK’s favour.
Manufacturing globally is becoming more capital intensive, which reduces the comparative advantage of developing countries with low labour costs.
At the same time, the dividing line between manufacturing and services is becoming more blurred. Manufacturers in developing countries may still produce parts, such as chips or engines, but the design, marketing and sales of the products may take place in developed countries, such as the UK. Indeed, as products become more sophisticated, an increasing amount of value added may occur in developed countries.
The UK may be particularly well-placed in this regard. It can provide many high-end services in IT, business support and financial services to international manufacturers. It may have a comparative advantage in idea-intensive production.
Finally with a higher exchange rate, the UK’s terms of trade have been improving. The downside is that it makes UK exports more expensive in foreign currency terms, but it also makes commodity prices cheaper, which have already fallen in dollar terms, and also the prices of imported component parts. This helps offset the effect of the appreciation of the exchange rate on exports.
The following article by Jeremy Warner considers whether, despite its poor performance in traditional manufacturing, the UK might have hit an economic ‘sweet spot’ in its trade position.

China has a key role in the global economy. Recording double digit growth for a number of years and posting impressive export figures, China’s has been an economy on an upward trajectory. But its growth has been slowing and this might spell trouble for the global economy, as was discussed in the following blog. For many, China is the pendulum and the direction it moves in will have a big influence on many other countries.
There are some suggestions that China’s rapid growth has been somewhat artificial, in particular following the financial crisis, where we saw massive investment by state-owner enterprises, banks and local government. This has led to a severe imbalance within the Chinese economy, with high levels of debt. One of the key factors that has enabled China to grow so quickly has been strong exports. China has typically had a large current account surplus, often balanced by large current account deficits in many Western countries.
The exchange rate is a key component in keeping strong export growth and the devaluation of the Chinese currency in August (see What a devalued yuan means to the rest of the world) is perhaps a suggestion that export growth in China is lower than desired. Devaluing the currency will boost the competitiveness of Chinese exports and this in turn may lead to a growth in the current account surplus, which had fallen quite significantly from around 10% to 2%.
The problem is that China is currently imbalanced and this is likely to create problems around the world. With globalisation, the free movement of capital and people, deflation in the West and falling world asset prices, the situation in China is crucial. Although you will find many articles about China and blogs on this site about its devaluation, its growth and policy, the BBC News article below considers the conflicts that exist between three key economic objectives:
1. currency stability
2. the free movement of capital
3. independent monetary policy
and the need for some international co-operation and co-ordination to enable China’s economy to return to internal and external balance.

- Would you suggest that China is suffering from an imbalanced economy? If so, which type of imbalance and why is this a problem for China and for the world economy?
- The article refers to the trilemma. Why can an country not achieve all 3 parts of the trilemma? You should explain why each combination of 2 aspects is possible, but why the third is problematic.
- Use a diagram to explain why a fall in the exchange rate will boost the competitiveness of exports and why this can create economic growth.
- Why is a devalued Chinese currency bad news for the rest of the world?
- How could international co-operation and co-ordination help China?
On August 11th, China devalued its currency, the yuan, by 1.9%. The next day it devalued it by a further 1.6% and on the next day by a further 1.1%. Even though the total devaluation was relatively small, especially given a much bigger revaluation over the previous three years (see chart below), traders in world markets greeted the news with considerable pessimism. Stock markets around the world fell. For example, the US Dow Jones was down by 1.1%, the FTSE 100 was down by 2.5% and the German DAX by 5.8%.
There are three major concerns of investors about the devaluation. The first is that a weaker yuan will make other countries’ exports more expensive in China, thereby making it harder to export to China. At the same time Chinese imports into the rest of the world will be cheaper, thereby making it harder for domestic producers to compete with Chinese imports.
The second is that cheaper Chinese imports will put downward pressure on prices at a time when inflation rates in the major economies are already below target rates. The fear of deflation has not gone away and this further deflationary twist will intensify such fears and possibly dampen demand.
The third is that the devaluation is taken as a sign that the Chinese authorities are worried about a slowing Chinese economy and are using the devaluation to boost Chinese exports. The rapidly expanding Chinese economy has been one of the major motors of the global economy in recent years and hence a slowing Chinese economy is cause for serious concern at a time when the global economy is still only very slowly recovering from the shock of the financial crisis of 2007–8
But just how worried should the rest of the world be about the falling yuan? And will it continue to fall, or could this be seen as a ‘one-off’ correction? What effect will it have on the macroeconomic policies of the USA, the eurozone and other major countries/regions? The following articles analyse Chinese policy towards its currency and the implications for the rest of the world.

In the late 2000s, Zimbabwe experienced hyperinflation. As a post on this site in January 2009 said, two estimates of the inflation rate were made: one of 5 sextillion per cent (5 and 21 zeros); the other of 6.5 quindecillion novemdecillion per cent (65 and 107 zeros). In January 2009, in a last attempt to save the Zimbabwean currency, a new series of banknotes was issued, including a Z$100 trillion note.
Prices were typically being adjusted at least twice a day and people had to carry large bags of money around even to buy a couple of simple items. The currency was virtually worthless. As the Guardian article below states:
Hyperinflation in Zimbabwe left pensions, wages and investments worthless and spread poverty as everyday items became unaffordable. It also caused severe cash shortages, because the government could not afford to print bank notes to keep pace with inflation.
The solution was to allow other currencies, mainly the US dollar and the South African rand, to be used alongside the local currency. Although the Zimbabwean currency was still legal tender, it effectively went out of use. Prices stabilised and since then inflation has been in single figures.
But many people still have stocks of the virtually worthless old currency, either in cash or in savings accounts. The Zimbabwean government has now said that it will exchange Zimbabwean dollar notes for US dollars at the rate of US$1 = Z$250tn (250,000,000,000). People have until September to do so. Up to now, they have mainly been used to sell as souvenirs to tourists! For people with Zimbabwean dollars in their bank accounts, they will get a minimum of US$5. For amounts beyond Z$175,000tn they will get an additional US dollar for each Z$35,000tn.
Historical examples of hyperinflation
As case study 15.5 in Economics 9e’s MyEconLab points out, several countries experienced hyperinflation after the First World War. In Austria and Hungary prices were several thousand times their pre-war level. In Poland they were over 2 million times higher, and in the USSR several billion times higher.
Germany in the 1920s
But even these staggering rates of inflation seem insignificant beside those of Germany. Following the chaos of the war, the German government resorted to printing money, not only to meet its domestic spending requirements in rebuilding a war-ravaged economy, but also to finance the crippling war reparations imposed on it by the allies in the Treaty of Versailles.
From mid 1921 the rate of monetary increase soared and inflation soared with it. By autumn 1923 the annual rate of inflation had reached a mind-boggling 7,000,000,000,000 per cent! As price increases accelerated, people became reluctant to accept money: before they knew it, the money would be worthless. People thus rushed to spend their money as quickly as possible. But this in turn further drove up prices. (The note shown above is in old billions, where a billion was a million million. So the note was for 50,000,000,000,000 marks.)
For many Germans the effect was devastating. People’s life savings were wiped out. Others whose wages were not quickly adjusted found their real incomes plummeting. Many were thrown out of work as businesses, especially those with money assets, went bankrupt. Poverty and destitution were widespread.
By the end of 1923 the German currency was literally worthless. In 1924, therefore, it was replaced by a new currency – one whose supply was kept tightly controlled by the government.
Serbia and Montenegro 1993–5
After the break-up of Yugoslavia in 1992, the economy of the remaining part of Yugoslavia (Serbia and Montenegro) collapsed. The government relied more and more on printing money to finance public expenditure. Prices soared.
The government attempted to control the inflation by imposing price controls. But these simply made production unprofitable and output fell further. The economy nosedived. Unemployment exceeded 30 per cent.
In October 1993, the government created a new currency, the new dinar, worth one million old dinars. In other words, six zeros were knocked off the currency. But this did not solve the problem. Between October 1993 and January 1994, prices rose by 5 quadrillion per cent (5 and fifteen zeros). Normal life could not function. Shops ran out of produce; savings were wiped out; barter replaced normal market activity.
At the beginning of January 1994 a ‘new new dinar’ was introduced, worth 1 billion new dinars. On 24 January this was replaced by a ‘novi dinar’ pegged 1 to 1 against the Deutsche Mark. This was worth approximately 13 million new new dinars. The novi dinar remained pegged to the Deutsche Mark and inflation was quickly eliminated.
