MACRO - exchange rates ✅ Flashcards
what is the exchange rate
The exchange rate of a currency is the weight of one currency relative to another
what is a floating exchange rate
The value of the exchange rate in a floating system is determined by the forces of supply and demand.
how do floating exchange rates work on a diagram
- In a floating exchange rate system, the market equilibrium price is at P1. When demand increases from D1 to D2, the exchange rate appreciates to P2.
- The demand for a currency is equal to exports plus capital inflows. The supply of a currency is equal to imports plus capital outflows.
what are causes of changes in the currency in a floating system
- Trade balances – countries with strong trade/current account surplus see currencies appreciate as money flows into circular flow for X of goods/services and investment income
- Foreign direct investment – attracts high net inflows of capital investment = increase in currency demand and rising exchange rate
- Portfolio investment – strong inflows of portfolio investment into equities/bonds from overseas = currency appreciation
- Interest rate differentials – high interest rate = ‘hot money’ flows coming in = appreciation
- Speculation – responsible for day-to-day volatility
what is a fixed exchange rate
- A fixed exchange rate has a value determined by the government compared to other currencies.
- In a fixed exchange rate system, the supply of the currency can be manipulated by the central bank, which can buy or sell the currency to change the price to where they want.
how can fixed exchange rates be demonstrated on a diagram
In the diagram, the supply has been increased (S1 to S2) by selling the currency so more is on the market (Q1 to Q3). The currency depreciates as a result (P2 -> P3), which makes exports more competitive.
what is a managed exchange rate system
- managed exchange rate systems combine the characteristics of fixed and floating exchange rate systems.
- The currency fluctuates, but it doesn’t float on a fully free market.
- This is when the exchange rate floats on the market, but the central bank of the country buys and sells currencies to try and influence their exchange rate.
examples of managed exchange rate systems
- The Japanese central bank has also attempted to make exports more competitive by manipulating the Yen, even though the Yen floats on the market.
- The Indian rupee fluctuates on the market, but the central bank intervenes when it falls outside a set range.
how do interest rates affect exchange rates
- An increase in interest rates, relative to other countries, makes it more attractive to invest funds in the country because the rate of return on investment is higher.
- This increases demand for the currency, causing an appreciation. This is known as hot money.
how can quantitative easing affect the money supply
- This is used by banks to help to stimulate the economy when standard monetary policy is no longer effective.
- This has inflationary effects since it increases the money supply, and it can reduce the value of the currency. QE is usually used where inflation is low and it is not possible to lower interest rates further.
what are foreign currency transactions
- The Bank of England uses this to manage the UK’s gold and foreign currency reserves, as well as managing the MPC’s pool of foreign currency reserves.
- It involves buying and selling foreign currency to manipulate the domestic currency.
- EG// China kept large reserves of the US Dollar by purchasing government bonds, in order to undervalue the Yuan.
what are changes in the exchange rate classified as and in which exchange rate system do they occur in
Depreciation is a fall in the value of a currency in a floating exchange rate system
Devaluation is a fall in the value of a currency in a fixed exchange rate system
Appreciation is a rise in the value of a currency in a floating exchange rate system
Revaluation is a rise in the value of a currency in a fixed exchange rate system
what is competitive devaluations/dirty floating and why is it used
- When country deliberately drives down value of currency to give competitive lift to demand, output, jobs in export industries
- Used in deflationary recession or to attract extra FDI
- Attractive for countries in trade deficit/rising unemployment
- Can be seen as form of trade protectionism inviting retaliatory action, eg import tariff
- Cutting exchange rate = harder for other countries to export negatively = affects growth rate = damages volume of trade taking place between nations
how do exchange rates affect business activity
- Price of X in international markets
- Overseas goods costs
- Overseas profits/revenues
- Converting cash receipts from customers overseas
impact of currency depreciation on macroeconomic objectives and wider objectives
INFLATION = high import prices = increased consumer prices. Helps country avoid deflation and lowers real interest rates
ECONOMIC GROWTH = weaker currency = stimulates GDP growth. But, depends upon PED for exports. Many exports require imported components = more expensive from depreciation
UNEMPLOYMENT = competitive currency = increase domestic production = positive export multiplier = stimulate AD and jobs
BALANCE OF TRADE = dependent upon PED for X/M, J Curve effect. Impact on X = dependent on strength of GDP in key export markets
BUSINESS INVESTMENT = help improve profitability
WIDER EFFECTS = similar to interest rate cut. Risks of higher costs of importing components/materials/prices of capital technologies
FDI = makes country’s FDI assets appear more valuable and FDI liabilities less valuable to overseas investors = reduce inwards FDI
who benefits and loses from a lower exchange rate
WINNERS = businesses exporting into international markets, businesses earning substantial profits in overseas currencies
LOSERS = overseas businesses trying to compete in the domestic market, businesses importing goods and services
what does currency depreciation AD stimulation depend on
- Length of time lag
- Scale of change in exchange rate
- If change is temporary/long lasting
- Coefficients of PED for X/M (Marshall Lerner condition)
- Size of multiplier/accelerator effects
- Which stage of economic cycle it takes place
- Type of economy – small developing vs large advanced
- Degree of openness to international trade
what are the risks of internal devaluation
- Loss of output/rising unemployment
- Fall in nominal wages = reduce living standards
- Risks from sustained deflation
- Real value of debt increases
- Danger of permanent loss of output (hysteria)
what are the drawbacks of external devaluation
- Increase in cost-push inflation = higher import prices
- Rise in inflation = reduces real incomes
- No guarantee trade deficit will improve (j curve)
- Foreign creditors demand higher interest rates on government/corporate debt
- Currency uncertainty = country less attractive to inward FDI
advantages of floating exchange rates
- reduces need for central bank to hold large currency reserves
- freedom to set interest rates to meet objectives
- help prevent imported inflation
- insulation for economy after external shock, especially export dependent countries
- partial automatic correction for current account deficit
- less risk of currency becoming over/undervalued
- automatically adjusts to economic shocks
evaluation of floating exchange rates
- no guarantee that floating exchange will be stable
- volatility in floating exchange detrimental to attracting inward investment
- lower exchange rate doesn’t always correct persistent balance of payments deficit
problems using exchange rates to measure GDP
- Exchange rates volatile from month to month and year to year
- Exchange rates more relevant to products traded between countries than non-traded products
- Calculations of GDP based on market exchange rates over-estimate cost of living in poorer developing countries (Balassa-Samuelson effect)
what is PPP
purchasing power parity theory
- PPP adjustment – basket of comparable goods/services and the price of these in different countries
- PPP is the exchange rate needed to buy the same quantity of products in each country
advantages of fixed exchange rate
Allows for firms to plan investment, because they know that they will not be affected by harsh fluctuations in the exchange rate.
It gives the monetary policy a focused target to work towards.
