Currency Exchange Rates - Factors Affecting Rates & Risk Mitigation Techniques Flashcards
What are the factors that affect exchange rates?
The 5 factors that affect currency exchange rates can be classified as three trade-related and two financial factors:
Trade-related factors
- Relative inflation rates
- Relative income levels
- Government intervention
Note: Trade-related factors influence the demand for goods, demand for and supply of currency and ultimately determines the exchange rate
Financial factors
- Relative interest rates
- Ease of capital flow
Note: Financial related factors influence the demand for securities, demand for and supply of currency and ultimately determines the exchange rate
How does relative inflation rates affect exchange rates?
Trade-related factor
When the rate of inflation in a given country rises relative to the rates of other countries, the demand for that country’s currency falls
This inward shift of the demand curve results from the lowered desirability of that currency (a result of its falling purchasing power)
As investors unload this currency, there is more of it available (reflected in an outward shift of the supply curve)
A new equilibrium point will be reached at a lower price in terms of investors’ domestic currencies
An investor’s domestic currency has gained purchasing power in the country where inflation is worse
How does relative income levels affect exchange rates?
Trade-related factor
Citizens with higher incomes look for new consumption opportunities in other countries, driving up the demand for those currencies and shifting the demand curve to the right
Thus, as incomes rise in one country, the prices of foreign currencies rise as well and the local currency will depreciate
How does government intervention affect exchange rates?
Trade-related factor
Actions by national governments, such as trade barriers and currency restrictions, complicate the process of exchange rate determination
How does relative interest rates affect exchange rates?
Financial factor
When interest rates in a given country rise relative to those of other countries, the demand for that country’s currency rises
This outward shift of the demand curve results from the influx of other currencies seeking the higher returns available in that country
As more and more investors buy up the high-interest country’s currency with which to make investments, there is less of it available (reflected in an inward shift of the supply curve)
A new equilibrium point will be reached at a higher price in terms of investors’ domestic currencies
An investor’s domestic currency has lost purchasing power in the country paying higher returns
How does ease of capital flow affect exchange rates?
Financial factor
If a country with high real interest rates loosens restrictions against the cross-border movement of capital, the demand for the currency will rise as investors seek higher returns
The speed with which capital can be moved electronically and the huge amounts involved in the “wired” global economy easily dominate the effects of the trade-related factors
What is the Interest rate parity (IRP) theory?
Simultaneous effects on exchange rates - Differential interest rates
Interest rate parity (IRP) theory holds that exchange rates will settle at an equilibrium point where the difference between the forward rate and the spot rate (i.e., the forward premium or discount) equals the exact amount necessary to offset the difference in interest rates between the two countries
Note: This theory deals with the forward rate and the explanatory variable is interest rates
What is the Purchasing power parity (PPP) theory?
Simultaneous effects on exchange rates - Differential inflation rates
Purchasing power parity (PPP) theory explains differences in exchange rates as the result of the differing inflation rates in the two countries
Note: This theory deals with the % change in sport rate and the explanatory variable is inflation rates
What is the International Fisher Effect (IFE) theory?
Simultaneous effects on exchange rates
International Fisher Effect (IFE) theory focuses on how the sport rate will change over time, but it uses interplay between real and nominal interest rates to explain the change
If all investors require a given real rate of return, then differences between currencies can be explained by each country’s expected inflation rate
Note: This theory deals with the % change in spot rate and the explanatory variable is interest rates
What does the Interest rate parity (IRP) theory suggest about high-inflation currencies?
Interest rate parity (IRP) theory suggest that high-inflation currencies usually trade at large forward discounts
What does the Purchasing power parity (PPP) theory suggest about high-inflation currencies?
Purchasing power parity (PPP) theory suggest that high-inflation currencies will weaken over time
What does the International Fisher Effect (IFE) theory suggest about high-inflation currencies?
International Fisher Effect (IFE) theory suggest that:
a. High-inflation currencies will weaken over time
b. Their (high-inflation) economies will have high interest rates
How are long-term exchange rates dictated by the Purchasing power parity (PPP) theorem?
(Exchange rate fluctuations over time)
In the long run, real prices should be the same worldwide (net of government taxes or trade barriers and transportation costs) for a given good. Exchange rates will adjust until purchasing-power parity is achieved
In other words, relative price levels determine exchange rates. In the real world, exchange rates do NOT perfectly reflect purchasing-power parity, but relative price levels are clearly important determinants of those rates
How are medium-term exchange rates dictated by the economic activity in a country?
(Exchange rate fluctuations over time)
When the U.S. is in a recession, spending on imports (as well as domestic goods) will decrease. This reduced spending on imports shifts the supply curve for dollars to the left, causing the equilibrium value of the dollar to increase (assuming the demand for dollars is constant); that is, at any given exchange rate, the supply to foreigners is less
If more goods are exported because of an increased preference for U.S. goods, the demand curve for dollars shifts to the right, causing upward pressure on the value of the dollar
An increase in imports or a decrease in exports will have effects opposite to those described above
How are short-term exchange rates dictated by interest rates?
(Exchange rate fluctuations over time)
Big corporations and banks invest their large reserves of cash where the real interest rate is highest. A rise in the real interest rate in a country will lead to an appreciation of the currency because it will be demanded for investment at the higher real interest rate, thereby shifting the demand curve to the right (outward)
The reverse holds true for a decline in real interest rates because that currency will be sold as investors move their money out of the country
However, the interplay of interest rates and inflation must also be considered. Inflation of a currency relative to a second currency causes the first currency to depreciate relative to the second. Also, nominal interest rates increase when inflation rates are expected to increase
