CHAPTER 4

• PARITY CONDITIONS AND CURRENCY FORECASTING

3
ARBITRAGE AND THE LAW OF ONE PRICE

• I. THE LAW OF ONE PRICE
• A. Law states
• Identical goods sell for the same price
  worldwide.

4
ARBITRAGE AND THE LAW OF ONE PRICE

• B. Theoretical basis
• If the prices after exchange-rate
• adjustment were not equal, arbitrage for the
  goods worldwide ensures that eventually they will.

5
ARBITRAGE AND THE LAW OF ONE PRICE

• C. Five Parity Conditions Result From These
  Arbitrage Activities
• 1. Purchasing Power Parity (PPP)
• 2. The Fisher Effect (FE)
• 3. The International Fisher Effect
• (IFE)
• 4. Interest Rate Parity (IRP)
• 5. Unbiased Forward Rate (UFR)

6
ARBITRAGE AND THE LAW OF ONE PRICE

• D. Five Parity Conditions Linked by
• 1. The adjustment of various
• rates and prices to inflation
• 2. The notion that money should have no
• effect on real variables (since they
• have been adjusted for price changes)

7
ARBITRAGE AND THE LAW OF ONE PRICE

• E. Inflation and home currency depreciation
• 1. jointly determined by the growth of
  domestic money supply
• 2. relative to the growth of
• domestic money demand

8
ARBITRAGE AND THE LAW OF ONE PRICE

• F. THE LAW OF ONE PRICE
• - enforced by international
• arbitrage.

9
PURCHASING POWER PARITY

• I. THE THEORY OF PURCHASING
• POWER PARITY
• states that spot exchange rates between
  currencies will change to the differential in
  inflation rates between countries.

10
PURCHASING POWER PARITY

• II. ABSOLUTE PURCHASING POWER PARITY
• A. Price levels adjusted for
• exchange rates should be
• equal between countries

11
PURCHASING POWER PARITY

• II. ABSOLUTE PURCHASING POWER PARITY
• B. One unit of currency has same purchasing
  power globally.

12
PURCHASING POWER PARITY

• III. RELATIVE PURCHASING POWER PARITY
• A. states that the exchange rate of one
  currency against another will adjust to
  reflect changes in the price levels of the
  two countries

13
PURCHASING POWER PARITY

• 1. In mathematical terms
• where et future spot rate
• e0 spot rate
• ih home inflation
• if foreign inflation
• t the time period

14
PURCHASING POWER PARITY

• 2. If purchasing power parity is expected to
  hold, then the best prediction for the one-period
  spot rate should be

15
PURCHASING POWER PARITY

• 3. A more simplified but less precise
  relationship is
• that is, the percentage change should be
  approximately equal to the inflation rate
  differential.

16
PURCHASING POWER PARITY

• 4. PPP states
• the currency with the higher inflation rate is
  expected to depreciate relative to the currency
  with the lower rate of inflation

17
PURCHASING POWER PARITY

• B. Real Exchange Rates
• the quoted or nominal rate adjusted for a
  countrys inflation rate is

18
PURCHASING POWER PARITY

• C. Real exchange rates
• 1. If exchange rates adjust to inflation
  differential, PPP states that real exchange
  rates stay the same.

19
PURCHASING POWER PARITY

• C. Real exchange rates (cont)
• 2. Competitive positions
• domestic and foreign firms are unaffected

20
THE FISHER EFFECT (FE)

• I. THE FISHER EFFECT (FE)
• A. Definition
• states that nominal interest rates (r) are a
  function of the real interest rate (a) and a
  premium (i) for inflation expectations.
• R a i

21
THE FISHER EFFECT

• B. Real Rates of Interest
• 1. Should tend toward equality
• everywhere through arbitrage.
• 2. With no government interference nominal
  rates vary by inflation differential or
• rh - rf ih - if

22
THE FISHER EFFECT

• C. According to the Fisher Effect
• countries with higher inflation rates have
  higher interest rates

23
THE FISHER EFFECT

• Due to capital market integration globally,
  interest rate differentials are eroding

24
THE INTERNATIONAL FISHER EFFECT

• I. IFE STATES
• A. the spot rate adjusts to the interest rate
  differential between two countries

25
THE INTERNATIONAL FISHER EFFECT

• IFE PPP FE

26
THE INTERNATIONAL FISHER EFFECT

• B. Fisher postulated
• 1. The nominal interest rate differential
  should
• reflect the inflation rate differential

27
THE INTERNATIONAL FISHER EFFECT

• B. Fisher also postulated
• 2. Expected rates of return are equal in
  the absence of government intervention

28
THE INTERNATIONAL FISHER EFFECT

• C. Simplified IFE equation
• (if rf is relatively small)

29
THE INTERNATIONAL FISHER EFFECT

• D. Implications of IFE
• 1. Currency with the lower interest rate is
  expected to appreciate relative to the one
• with a higher rate

30
THE INTERNATIONAL FISHER EFFECT

• D. Implications of IFE (cont)
• 2. Financial market arbitrage
• insures interest rate differential is an
  unbiased predictor of change in future
  spot rate.

31
INTEREST RATE PARITY THEORY

• I. INTRODUCTION
• A. The Theory states
• the forward rate (F) differs from the spot
  rate (S) at equilibrium by an amount equal to
  the interest differential (rh - rf) between two
  countries

32
INTEREST RATE PARITY THEORY

• 1. The forward premium or
• discount equals the interest
• rate differential.
• (F - S)/S (rh - rf)
• where rh the home rate
• rf the foreign rate

33
INTEREST RATE PARITY THEORY

• 2. In equilibrium, returns on currencies will be
  the same
• i. e. No profit will be realized and interest
  parity exists which can be written

34
INTEREST RATE PARITY THEORY

• B. Covered Interest Arbitrage
• 1. Conditions required
• interest rate differential does not equal the
  forward premium or discount
• 2. Funds will move to a country
• with a more attractive rate.

35
INTEREST RATE PARITY THEORY

• 3. Market pressures develop
• a. As one currency is more demanded spot and
  sold forward
• b. Inflow of fund depresses interest rates
• c. Parity eventually reached

36
INTEREST RATE PARITY THEORY

• C. Summary
• Interest Rate Parity states
• 1. Higher interest rates on a currency
  are offset by forward discounts
• 2. Lower interest rates are offset by forward
  premiums

37
THE FORWARD AND THE FUTURE SPOT RATE

• I. THE UNBIASED FORWARD RATE
• A. States that, if the forward rate (ft ) is
  unbiased, then it should reflect the expected
  future spot rate (et)
• B. Stated as
• ft et

38
CURRENCY FORECASTING

• I. FORECASTING MODELS
• A. Created to forecast exchange rates in
  addition to parity conditions
• B. Two types of forecast
• 1. Market-based
• 2. Model-based

39
CURRENCY FORECASTING

• 1. MARKET-BASED FORECASTS
• derived from market indicators
• a. The current forward rate contains implicit
  information about exchange rate changes for one
  year
• b. Interest rate differentials may be used to
  predict exchange rates beyond one year

40
CURRENCY FORECASTING

• 2. MODEL-BASED FORECASTS
• include fundamental and technical analysis
• a. Fundamental relies on key macroeconomic
  variables and policies which most like affect
  exchange rates.
• b. Technical relies on use of
• 1.) Historical volume and price data
• 2.) Charting and trend analysis
