exchange rates Flashcards
what is a fixed exchange rate?
when the official exchange rate is fixed to another countrys currency
what is needed for a fixed exchange rate to be maintained?
govt/ central bank needs to hold large amounts of domestic and foreign currency reserves
what does the govt need to do if the exchange rate equilibrium is higher than the fixed exchange rate?
- use the currency reserves its got (needs to sell the pound currency reserves its got)
- buy foreign currencies instead
- this will increase the supply of the pound and reduce the exchange rate
- this reduced value of the exchange rate at equilibrium should equal the fixed exchange rate
draw a diagram to show the reduction in the value of the exchange rate?
this is how you can reduce the value of the exchange rate when there is a fixed exchange rate or when theres pressure on it rising
how would the govt push up the exchange rate if the initial equilibrium is lower than the fixed exchange rate?
- govt needs to increase demand for the pound by using their foreign currency reserves to buy up more of the pound in the market
- this increases the value of the pound
- this increase in the exchange rate (which is the exchange rate at initial equilibrium) should now equal the fixed exchange rate
draw a diagram to show the value of the exchange rate decreasing
how can the govt change the fixed exchange rate?
if the UK govt decides they want to change the fixed exchange rate they can devalue the pound
what is depreciation of exchange rate?
depreciation is when the floating exchange rate falls in value
what is appreciation of the exchange rate?
appreciation is when the floating exchange rate increases in value
what do you say when referring to the change in the value of the exchange rate
when it comes to fixed exchange rate you say devalue or revalue
what is a floating exchange rate?
floating exchange rate is when a nations currency is set through supply and demand
what does it mean when theres a trade imbalance/ current account deficit?
- importing more than exporting
- more supply of the pound than demand for the pound
- (have to exchange the pound in order to buy foreign imports by exchanging the pound for a foreign currency
- this depreciates the pound
what happens when a currency depreciates in terms of the CA?
- whenever a currency depreciates, imports become more expensive and exports become cheaper
- this, in theory, should reduce the demand for imports which could help resolve the current account deficit
what determines the supply and demand of a currency
speculation tends to drive the demand and supply of a currency
investment (FDI)
sale of exports
what are the arguments for using a floating exchange rates?
reduces the need for currency reserves
freedom for domestic monetary policy
useful instrument for macroeconomic adjustment
partial automatic correction for a trade deficit
reduced risk of currency speculation
resource allocation
why do floating exchange rates reduce the need for currency reserves?
a floating exchange rate doesnt need large levels of currency reserves whereas fixed exchange rates do in order to maintain them which can be costly and may not be viable
why do floating exchange rates cause freedom for monetary policy?
- some fixed exchange rate systems will require the manipulation of interest rates in order to keep an exchange rate fixed to a certain currency
- whereas in a floating exchange rate there is no need to change interest rates to keep the exchange rate fixed
- you can use monetary policy to deal with domestic issues in the economy such as inflation
why is floating exchange rates a useful instrument for macroeconomic adjustment?
reduction in exchange rate could help e.g increase growth by increasing exports
how do floating exchange rates cause partial automatic correction for a trade deficit?
-for example if a country has a large current account deficit/ trade deficit a floating exchange rate increases the supply of the currency which will reduce the value of the currency
- makes imports more expensive and exports cheaper
- this could help partially correct a current account deficit
what is speculation
when someone who invests in foreign currency buys some currency in the hopes of selling it at an appreciated rate when market fluctuations happen
how do floating exchange rates reduce the risk of currency speculation?
- in a floating exchange rate system, exchange rates should reach an equilibrium which reflects purchasing power parity
- the currency is valued perfectly (not over or undervalued)
- therefore the risk of speculative attacks are less likely to occur especially if a currency is overvalued
- more stability as exchange rate is at equilibrium
recall the arguments against floating exchange rates?
self correction of trade deficits unlikely to occur
inflation rates causes issues with export competitiveness
volatility
