Q

Explain how Trade balances can cause a change in currency in a floating system

A

countries that have strong trade and current account surpluses tend (other factors remaining
the same) to see their currencies appreciate as money flows into the circular flow from exports of goods and services and from investment income

demand for exports tends to affect the demand for currency curve - because if people overseas want to buy UK exports they will need to buy £s in order to pay for them

whereas demand for imports tends to affect the supply of currency - because we need to
supply £s to the foreign exchange market to buy foreign currencies to pay for imports

Q

Why could Foreign direct investment cause changes in a floating currency

A

an economy that attracts high net inflows of capital investment (i.e. long-term capital flows) from overseas will see an increase in currency demand and a rising exchange rate

Q

Why would interest rate differentials cause changes in the currency in a floating system

A

countries with relatively high-interest rates can expect to see ‘hot money’ (i.e. short-
term capital) flowing coming in and causing an appreciation of the exchange rate.

Q

What are the 3 usual factors of a managed exchange rate

A
  • Currency is usually set by market forces
  • A central bank may intervene occasionally to influence the price
  • In a managed floating system, the currency becomes a key target or monetary policy
22
Q

What a policy tool for managing floating exchange rates

A
  • Changes in monetary policy interest rates
  • Quantitative easing
  • Direct buying/selling in the currency market (intervention)
  • Taxation of overseas currency deposits and capital control
23
Q

Hence, explain how a central bank can influence the value of a currency using interest rate (monetary policy)

A
  • Central bank could influence the external value by changing the interest rates
  • Therefore a depreciation through a fall in interest rates
  • Causes a reduction in the returns on overseas money being held in country’s banking system - real return may become negative
  • This may hence cause an outflow of ‘hot money’ from commercial banks to other countries
  • Will cause an outward shift in the supply curve for the currency as investors look for currencies with higher expected returns
  • Assume all other factors are constant could cause a depreciation
24
Q

What are competitive devaluations

When may a country do this

A

occur when a country deliberately intervenes to drive down the value of their
currency to provide a competitive lift to demand, output and jobs in their export industries

They may try this when faced with a deflationary recession or perhaps to attract extra foreign investment, for nations with persistent trade deficits and rising unemployment

25
Q

What are the key problems with Competitive devaluations

A
  • can be seen by other countries as a form of trade protectionism that invites some form of retaliatory action such as an import tariff
  • makes it harder for other countries to export negatively affecting their growth rate
    which in turn can damage the volume of trade that takes place between nations
  • go against the principles of trade based on comparative advantage
26
Q

What are the 3 key features of a fixed exchange rate

A
  • The Government/central bank fixes the currency value
  • Pegged exchange rate becomes official rate
  • Adjustable Peg
27
Q

What does it mean when a country has Pegged exchange rate

A

External value is pegged to one or more currencies (known as the anchor currency)

The central bank must hold sufficient foreign exchange reserves in order to intervene in currency market to maintain the fixed peg

28
Q

With a Fixed exchange rate, how would the central bank increase the value of the domestic currency

A

They may need to buy domestic currency using foreign currency

29
Q

What are the 4 ways exchange rates, impact business activity

A
  1. Price of exports in international markets
  2. Cost of goods bought from overseas
  3. Revenues and profits earned overseas
  4. Converting cash receipts from customers overseas
30
Q

Who are the winners from a lower exchange rate

A
  • Businesses earning substantial profits in overseas currencies
  • Businesses exporting into international markets
31
Q

Who are the losers from a low-interest rate

A
  • Business importing good/serivces
  • Overseas businesses trying to compete in the domestic market
32
Q

What does SPICED stand for

A

Strong Pound Imports Cheaper Export Dearer

33
Q

A currency depreciation usually has a similar effect on the macro-economy as

A

a cut in interest rates

34
Q

A currency depreciation may help to provide a partial auto-correction of a

A

large trade deficit

35
Q

How can inflation be impacted by a currency depreciation

Why can this be problematic?

A

Higher import prices feed into increased consumer prices

help a country to avoid deflation and it also lowers real interest rates

threatens real living standards especially for groups with weak bargaining power for wages

36
Q

How does the currency depreciating impact on economic growth

How is this problemetic

A

A weaker currency is usually a stimulus to GDP growth due to higher net exports

But this depends on the price elasticity of demand for exports

Also, many exports are made from imported components which will have become more expensive as a result of the depreciation (capital goods)

37
Q

How does the currency depreciating impact on unemployment

A

A more competitive currency will help to increase domestic production and perhaps create a
positive export multiplier effect which will further stimulate aggregate demand and jobs.

38
Q

How does a currency depreciating impact on the balance of trade

A

Trade deficit may grow in initial period after depreciation

This is because the price elasticities of demand for exports & imports are likely to be inelastic in the short term

The impact on export sales also depends in part on the strength of GDP growth in key export
markets

39
Q

How does a depreciating currency affect business investment

A

Should help to improve profitability

because a fall in the value of the Pound increases the overseas earnings of UK companies in foreign currency which will now be worth more in Pounds

40
Q

How does a depreciating currency affect wider investment

A

Depreciation is similar to a cut in interest rates therefore an expansion of monetary policy

Therefore reduced price levels for businesses

but there are risks too – including higher costs of importing components, raw materials and prices of important capital technologies.

41
Q

How does a depreciating currency affect FDI

A

Depreciation of a currency makes a country’s FDI assets appear more valuable when converted into the domestic currency

Likewise, FDI liabilities (i.e. investment in UK) appear less valuable to overseas investors. This can
ultimately therefore reduce inwards FDI.

42
Q

Using a chain of reasoning, explain how a currency depreciation can affect international competitiveness

A
  • A depreciation could result in exporters reducing the price of goods/services sold overseas
  • This makes UK exports relatively cheaper in overseas markets - export prices fall leading to improved competitiveness
  • UK price of imported products will increase
  • A rise in import prices will make domestic producers in the UK appear relatively more competitive in price terms
43
Q

A depreciation of the exchange rate provides a stimulus for aggregate demand

But this depends on…

A
  1. Time lags for consumers/businesses to respond
  2. Scale of change in the exchange rate
  3. How long the change lasts for
  4. Price elasticity for imports/exports (J-curve)
  5. Multiplier or accelerator affects
  6. When in the economic cycle the change occurs
  7. Type of economy
  8. Degree of openness the economy has
44
Q

What are the advantages of a floating exchange rate

A
  • reduces the need for central bank to hold large currency reserves
  • Freedom to set monetary policy interest rates to meet domestic objectives
  • May help imported inflation
  • Insulation for an economy after an external shock
  • Partial automatic correction of a current account deficit
  • Less risk of a currency becomes significantly over/undervalued
45
Q

What are the problems with a floating exchange rate

A
  • No guarantee that floating exchange rates will be stable
  • Volatility in a floating currency might be detrimental to attracting inward investment
  • A lower (more competitive) exchange rate doesn’t necessarily correct a BoP deficit
    • consider J curve theory and the importance of non-price competitiveness
46
Q

A currency appreciation makes exports more expensive and likely lead to a …… shift of AD

A

inward

47
Q

A currency appreciation makes imports cheaper and likely to cause an ……. shift in AS

A

Outward

48
Q

What are the advantages of a Fixed exchange rate

A
  • Certainty of currency value gives confidence for inward investment from overseas businesses
  • Reduced costs of “currency hedging” for businesses such as airlines
  • Currency stability helps to control inflation
  • A stable currency can lead to lower borrowing costs
  • Imposes responsibility on government macro policies
  • Less speculation in the currency market if the fixed exchange rate is regarded by traders as credible
49
Q

What are the problems with a fixed exchange rate

A
  • Reduced freedom to use interest rates for other macro objectives
  • Many developing countries do not have sufficient foreign currency reserves
  • Difficult for countries to use a competitive devaluation of their fixed exchange rate – this creates political tensions and might lead to a protectionist response
  • Devaluation of a fixed exchange rate can lead to a surge in cost-push inflation – this is damaging for competitiveness and has regressive effects on poorer families
50
Q

What type of country would a fixed exchange rate be favourable for

A

for developing countries wanting to control inflation

51
Q

What type of country would favour a managed floating rate

A

Export-dependent economies may favour a managed floating rate e.g. to offset fluctuating world prices
