1.Exchange Rate Systems
1.1 / Exchange Rate Systems(a)Fixed exchange rates–This involves publishing the target parity against a single currency (or a basket of currencies), and a commitment to use monetary policy (interest rates) and official reserves of foreign exchange to hold the actual spot rate within some trading band around this target.
(i)Fixed against a single currency–This is where a country fixes its exchange rate against the currency of another country’s currency. More than 50 countries fix their rates in this way, mostly against the US dollar. Fixed rates are not permanently fixed and periodic revaluations and devaluations occur when the economic fundamentals of the country concerned strongly diverge (e.g. inflation rates).
(ii)Fixed against a basket of currencies–Using a basket of currencies is aimed at fixing the exchange rate against a more stable currency base than would occur with a single currency fix. The basket is often devised to reflect the major trading links of the country concerned.
(b)Freely floating exchange rates (or clean float) – A genuine free float would involve leaving exchange rates entirely to the vagaries of supply and demand on the foreign exchange markets, and neither intervening on the market using official reserves of foreign exchange nor taking exchange rates into account when making interest rate decisions. The Monetary Policy Committee of the Bank of England clearly takes account of the external value of sterling in its decision-making process, so that although the pound is no longer in a fixed exchange rate system, it would not be correct to argue that it is on a genuinely free float.
(c)Managed floating exchange rates (or dirty float)–The central bank of countries using a managed float will attempt to keep currency relationships within a predetermined range of values (not usually publicly announced), and will often intervene in the foreign exchange markets by buying or selling their currency to remain within the range.
2.Types of Foreign Currency Risk
(Pilot, Dec 09, Jun 13)
2.1Currency risk
2.1.1Currency risk occurs in three forms: transaction exposure (short-term), economic exposure (effect on present value of longer term cash flows) and translation exposure (book gains or losses).
2.2Transaction risk
2.2.1 / Transaction RiskTransaction risk is the risk of an exchange rate changing between the transaction date and the subsequent settlement date, i.e. it is the gain or loss arising on conversion.
It arises primarily on import and exports.
2.2.2 / Example 1
A UK company, buy goods from Redland which cost 100,000 Reds (the local currency). The goods are re-sold in the UK for £32,000. At the time of the import purchases the exchange rate for Reds against sterling is 3.5650 – 3.5800.
Required:
(a)What is the expected profit on the re-sale?
(b)What would the actual profit be if the spot rate at the time when the currency is received has moved to:
(i)3.0800 – 3.0950
(ii)4.0650 – 4.0800?
Ignore bank commission charges.
Solution:
(a)The UK company must buy Reds to pay the supplier, and so the bank is selling Reds. The expected profit is as follows.
£
Revenue from re-sale of goods / 32,000,00
Less: Cost of 100,000 Reds in sterling (÷3.5650) / 28,050.49
Expected profit / 3,949.51
(b)(i)If the actual spot rate for the UK company to buy and the bank to sell the Reds is 3.0800, the result is as follows.
£
Revenue from re-sale of goods / 32,000,00
Less: Cost of 100,000 Reds in sterling (÷3.0800) / 32,467.53
Loss / (467.53)
(b)(ii)If the actual spot rate for the UK company to buy and the bank to sell the Reds is 4.0650, the result is as follows.
£
Revenue from re-sale of goods / 32,000,00
Less: Cost of 100,000 Reds in sterling (÷4.0650) / 24,600.25
Profit / 7,399.75
This variation in the final sterling cost of the goods (and thus the profit) illustrated the concept of transaction risk.
2.2.3A firm decide to hedge – take action to minimize– the risk, if it is:
(a)a material amount
(b)over a material time period
(c)thought likely exchange rates will change significantly.
2.2.4As transaction risk has a potential impact on the cash flows of a company, most companies choose to hedge against such exposure. Measuring and monitoring transaction risk is normally an important component of treasury management.
2.3Economic risk
2.3.1 / Economic RiskEconomic risk is the variation in the value of the business (i.e. the present value of future cash flows) due to unexpected changes in exchange rates. It is the long-term version of transaction risk.
2.3.2For example, a UK company might use raw materials which are priced in US dollars, but export its products mainly within the EU. A depreciation of sterling against the dollar or an appreciation of sterling against other EU currencies will both erode the competitiveness of the company. Economic exposure can be difficult to avoid, although diversification of the supplier and customer base across different countries will reduce this kind of exposure to risk.
2.4Translation risk
2.4.1 / Translation RiskThis is the risk that the organization will make exchange losses when the accounting results of its foreign branches or subsidiaries are translated into the home currency. Translation losses can result, for example, from restating the book value of a foreign subsidiary’s assets at the exchange rate on the statement of financial position date.

(ACCA F9 Financial Management Pilot Paper 2014)
3.The Causes of Exchange Rate Fluctuations
3.1Balance of payments
3.1.1Changes in exchange rates result from changes in the demand for and supply of the currency. These changes may occur for a variety of reasons, e.g. due to changes in international trade or capital flows between economies.
3.1.2Balance of payments(國際收支平衡)–Since currencies are required to finance international trade, changes in trade may lead to changes in exchange rates. In principle:
(a)demand for imports in the US represents a demand for foreign currency or a supply of dollars.
(b)overseas demand for US exports represents a demand for dollars or a supply of the currency.
(國際收支平衡是一個帳目，把一個國家與其他國家的交易記錄下來。這個記錄主要是記下一些涉及金錢或有價值的經濟活動，好些沒有金錢的經濟活動，如甲國有五萬人移民往乙國，這是不會記下的。)
3.1.3Thus a country with a current account deficit where imports exceed exports may expect to see its exchange rate depreciate, since the supply of the currency (imports) will exceed the demand for the currency (exports).
3.2Capital movements
3.2.1There are also capital movements between economies. These transactions are effectively switching bank deposits from one currency to another. These flows are now more important than the volume of trade in goods and services.
3.2.2Thus supply/demand for a currency may reflect events on the capital account. Several factors may lead to inflows or outflows of capital:
(a)changes in interest rates: rising (falling) interest rates will attract a capital inflow (outflow) and a demand (supply) for the currency
(b)inflation: asset holders will not wish to hold financial assets in a currency whose value is falling because of inflation.
3.3Purchasing power parity theory (PPP)(購買力平價學說)
(Pilot, Jun 11, Jun 12)
3.3.1 / Purchasing Power ParityPPP claims that the rate of exchange between two currencies depends on the relative inflation rates within the respective countries. In equilibrium, identical goods must cost the same, regardless of the currency in which they are sold.
PPP predicts that the country with the higher inflation will be subject to a depreciation of its currency.
Formally, if you need to estimate the expected future spot rates, PPP can be expressed in the following formula:
Where: S0 = Current spot rate
S1 = Expected future rate
hb = Inflation rate in country for which the spot is quoted (base country)
hc = Inflation rate in the other country (country currency).
3.3.2 / Example 2
An item costs $3,000 in the US.
Assume that sterling and the US dollar are at PPP equilibrium, at the current spot rate of $1.50/£, i.e. the sterling price x current spot rate of $1.50 = dollar price.
The spot rate is the rate at which currency can be exchanged today.
The US market / The UK market
Cost of item now / $3,000 / $1.50 / £2,000
Estimated inflation / 5% / 3%
Cost in one year / $3,150 / £2,060
The law of one price states that the item must always cost the same. Therefore in one year:
$3,150 must equal £2,060, and also the expected future spot rate can be calculated:
$3,150 / £2,060 = $1.5291/£
By formula:
3.3.3 / Test your understanding 1
The dollar and sterling are currently trading at $1.72/£.
Inflation in the US is expected to grow at 3% pa, but at 4% pa in the UK.
Predict the future spot rate in a year’s time.
Solution:
3.3.4 / Case Study – Big Mac Index
An amusing example of PPP is the Economist’s Big Mac Index. Under PPP movements in countries’ exchange rates should in the long-term mean that the prices of an identical basket of goods or services are equalized. The McDonalds Big Mac represents this basket.
The index compares local Big Mac prices with the price of Big Macs in America. This comparison is used to forecast what exchange rates should be, and this is then compared with the actual exchange rates to decide which currencies are over and under-valued.
3.3.5PPP can be used as our best predictor of future spot rates; however it suffers from the following major limitations:
(a)the future inflation rates are only estimates
(b)the market is dominated by speculative transactions (98%) as opposed to trade transactions; therefore PPP breaks down
(c)government intervention – governments may manage exchange rates, thus defying the forces pressing towards PPP.
3.3.6However, it is likely that the PPP may be more useful for predicting long-run changes in exchange rates since these are more likely to be determined by the underlying competitiveness of economies, as measured by the model.
3.4Interest rate parity theory (IRP)(利率平價學說)
(Jun 11, Dec 14)
3.4.1 / Interest Rate Parity (IRP)The IRP claims that the difference between the spot and the forward exchange rates is equal to the differential between interest rates available in the two currencies.
IRP predicts that the country with the higher interest rate will see the forward rate for its currency subject to a depreciation.
If you need to calculate the forward rate in one year’s time:
Where: F0 = Forward rate
S0 = Current spot rate
ib = interest rate for base currency
ic = interest rate for counter currency
3.4.2 / Example 3
UK investor invests in a one-year US bond with a 9.2% interest rate as this compares well with similar risk UK bonds offering 7.12%. The current spot rate is $1.5/£.
When the investment matures and the dollars are converted into sterling, IRP states that the investor will have achieved the same return as if the money had been invested in UK government bonds.
In 1 year, £1.0712 million must equate to $1.638 million so what you gain in extra interest, you lose on an adverse movement in exchange rates.
The forward rates moves to bring about interest rate parity amongst different currencies:
$1.638 ÷£1.0712 = $1.5291
By formula:
3.4.3The IRPT generally holds true in practice. There are no bargain interest rates to be had on loans/deposits in one currency rather than another. However, it suffers from the following limitations:
(a)government controls on capital markets
(b)controls on currency trading
(c)intervention in foreign exchange markets.
3.4.4The interest rate parity model shows that it may be possible to predict exchange rate movements by referring to differences in nominal exchange rates. If the forward exchange rate for sterling against the dollar was no higher than the spot rate but US nominal interest rates were higher, the following would happen:
(a)UK investors would shift funds to the US in order to secure the higher interest rates, since they would suffer no exchange losses when they converted $ back to £.
(b)the flow of capital from the UK to the US would raise UK interest rates and force up the spot rate for theUS$.
3.5Expectations theory
(Jun 12)
3.5.1The expectations theory claims that the current forward rate is an unbiased predictor of the spot rate at that point in the future.
3.5.2If a trader takes the view that the forward rate is lower than the expected future spot price, there is an incentive to buy forward. The buying pressure on the forward rates raises the price, until the forward price equals the market consensus view on the expected future spot price.
3.6The International Fisher Effect
3.6.1The International Fisher Effect claims that the interest rate differentials between two countries provide an unbiased predictor of future changes in the spot rate of exchange.
3.6.2The International Fisher Effect assumes that all countries will have the same real interest rate, although nominal or money rates may differ due to expected inflation rates. Thus the interest rate differential between two countries should be equal to the expected inflation differential. Therefore, countries with higher expected inflation rates will have higher nominal interest rates, and vice versa.
3.6.3The currency of countries with relatively high interest rates is expected to depreciate against currencies with lower interest rates, because the higher interest rates are considered necessary to compensate for the anticipated currency depreciation.
3.6.4Given free movement of capital internationally, this idea suggests that the real rate of return in different countries will equalize as a result of adjustments to spot exchange rates. The International Fisher Effect can be expressed as:
Where: ia = the nominal interest rate in country a
ib = the nominal interest rate in country b
ha = the inflation rate in country a
hb = the inflation rate in country b
3.7Four-way equivalence
3.7.1The four theories can be pulled together to show the overall relationship between spot rates, interest rates, inflation rates and the forward and expected future spot rates. As shown above, these relationships can be used to forecast exchange rates.
