Market Characteristics:An Interbank Market

• The spot market is a market for immediate delivery 92 to 3 days).

• Primarily an interbank market, which is the trading of foreign-currency-denominated deposits between large banks.

• Approximately $US2 trillion daily in global transactions.

Market Quotes: The WSJ Currency Trading Table

• Provides spot and forward rates. Forward rates are for forward contracts, or the future delivery of a currency.

• US $ equivalent is the dollar price of a foreign currency (home currency price of a foreign currency).

• Currency per US $ is the foreign currency price of one US dollar (foreign currency price of the home currency)

Appreciating and Depreciating Currencies

• A currency that has lost value relative to another currency is said to have ?

• A currency that has gained value relative to another currency is said to have ?

Page 8: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Appreciating and Depreciating Currencies

• A currency that has lost value relative to another currency is said to have depreciated.

• A currency that has gained value relative to another currency is said to have appreciated.

• These terms relate to the market process and are different from devaluation and revaluation.

Page 9: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Appreciating and Depreciating Currencies

• We use the percentage change formula to calculate the amount of depreciation/appreciation.

• Example, on Monday, the peso traded at 0.1021 $/P. On Tuesday the market closed at 0.1025 $/P.

• The peso has appreciated, as it now takes more $ to purchase each peso.

Page 10: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Appreciating and Depreciating Currencies

• Example, on Monday, the peso traded at 0.1021 $/P. On Tuesday the market closed at 0.1025 $/P.

• The amount of appreciation is:

[(0.1025 - 0.1021)/0.1021] * 100 = 0.39%

1.0039 414% 142%

Page 11: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Bid - Ask Spreads:Example from Financial Times

• The bid is the price the bank is willing to pay for the currency, e.g., 1.2002 $/€ is the bid on the euro in terms of the dollar.

• The ask is what the bank is willing to sell the currency for, e.g. 1.2010 $/€, is the ask on the euro in terms of the dollar.

Page 12: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Bid - Ask Spread:Cost of Transacting

• The bid - ask spread of a currency reflects, in general, the cost of transacting in that currency.

• It is calculated as the difference between the ask and the bid.

• Example, 1.2020 - 1.2002 = 0.0018.

Page 13: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Bid - Ask Margin:Percent Cost of Transacting

• The bid - ask spread can be converted into a percent to compare the cost of transacting among a number of currencies.

• The margin is calculated as the spread as a percent of the ask.

• (Ask - Bid)/Ask * 100• Example, (1.2020 - 1.2002)/1.2020 * 100 = 0.15%.

Page 14: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Cross-Rates: Unobserved Rates• A cross-rate is an unobserved rate that is

calculated from two observed rates.

• For example, the spot rate for the Canadian dollar is 0.70 $/C$, and the spot rate on the euro is 1.02 $/€. What is the Canadian dollar price of the euro (C$/€)?

Page 15: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Cross-Rates: Unobserved Rates• A cross-rate is an unobserved rate that is

calculated from two observed rates.• For example, the spot rate for the

Canadian dollar is 0.70 $/C$, and the spot rate on the euro is 1.02 $/€. What is the Canadian dollar price of the euro (C$/€)?

• Note that ($/€)/($/C$) = ($/€)*(C$/$)=C$/€.

• In this example, 1.02/0.70 = 1.457 C$/€.

Page 16: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Arbitrage:Consistency of Cross Rates

• Arbitrage is the simultaneous buying and selling to profit (as opposed to speculation).

• The ability of market participants to arbitrage guarantees that cross rates will be, in general, consistent.

• If a cross rate is not consistent, the actions of currency traders (arbitrage) will bring the respective currencies in line.

Page 17: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Spatial Arbitrage• Spatial Arbitrage refers to buying a

currency in one market and selling it in another.

• Price differences arise from geographical (spatial) dispersed markets.

• Due to the low-cost rapid-information nature of the foreign exchange market, these prices differences are arbitraged away quickly.

Page 18: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Triangular Arbitrage• Triangular arbitrage involves a third

currency and/or market.

• Arbitrage opportunities exist if an observed rate in another market is not consistent with a cross-rate (ignoring transaction costs).

Page 19: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Triangular Arbitrage: An Example

• The British pound is trading for 1.455 ($/£) and the Thai baht for 0.024 ($/b) in New York, while the Thai baht is trading for 0.012 (£/b) in London.

• Does an arbitrage opportunity exist?

Page 20: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Triangular Arbitrage: An Example

• The British pound is trading for 1.455 ($/£) and the Thai baht for 0.024 ($/b) in New York, while the Thai baht is trading for 0.012 (£/b) in London.

• The cross-rate in New York is:0.024/1.455 = 0.016 (£/b)

• Hence, an arbitrage opportunity exists.

Page 21: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Triangular Arbitrage: An Example

• The British pound is trading for 1.455 ($/£) and the Thai baht for 0.024 ($/b) in New York, while the Thai baht is trading for 0.012 (£/b) in London.

• The cross-rate in New York is:0.024/1.455 = 0.016 (£/b)

• Hence, an arbitrage opportunity exists.• How do you exploit it?

Page 22: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Example Continued

• “Buy low, sell high.”

• A trader with $1, could buy £0.687 in New York.

• The £0.687 would purchase b57.274 in London.

• The b57.274 purchases $1.375 in New York, or 37.5% profit on the transaction.

Real Exchange Rates:Real Exchange Rates: Measuring Relative Measuring Relative Purchasing PowerPurchasing Power

Page 24: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Real Exchange RatesReal Measures

• Nominal variables, such as exchange rates, do not consider changes in prices over time.

• Real variables, on the other hand, include price changes.

• A real exchange rate, therefore, accounts for relative price changes.

Page 25: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Real Exchange Rates

• A nominal exchange rate indicates the purchasing power of one nation’s currency over the currency of another nation.

• Real exchange rates indicate the purchasing power of a nation’s residents for foreign goods and services relative to their purchasing power for domestic goods and services.

• A real exchange rate is an index. Hence, we compare its value for one period against its value in another period.

Page 26: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Real Exchange RatesAn Example

• In 2000 the spot rate between the dollar and the pound was 1 USD = 0.6873 GSB (£/$).

• Yesterday the rate was 1 USD = 0.5100 GBP.• Hence, the pound appreciated relative to the dollar

by 26 percent {[(0.5100-0.6873)/0.6873]*100}.• Based on this alone, the purchasing power of US

residents for British goods and services (relative to US goods and services) fell by 26 percent.

Page 27: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Example: Continued• Suppose in 2000 the British CPI was 156.4 and

the US CPI was 154.7. In early 2006, the CPI’s were 170.5 and 172.7 respectively.

• Based on this, British prices rose 9.0 percent while US prices rose 11.6 percent, a 2.6 difference.

• Since the prices of British goods and services rose slower than the prices of US goods and services, there was an increase in purchasing power of British goods and services relative to the purchasing power of US goods and services.

Page 28: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Combining the Two Effects

• A real exchange rate combines these two effects - the fall in purchasing power of US residents due to the nominal appreciation of the pound and the gain in relative purchasing power due to British prices rising at a slower rate than US prices.

• To construct a real exchange rate, the spot rate, as it is quoted here, is multiplied by the ratio of the US CPI to the UK CPI.

(£/$) x (US CPI/UK CPI)

Page 29: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Combining the Two Effects

• 2000 Real Rate = 0.6873 x (154.7/156.4) = 0.6798

• 2007 Real Rate = 0.51 x (172.7/170.5) = 0.52.

• The real appreciation of the pound was only 24 percent.

Page 30: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Conclusion• The nominal exchange rate change resulted in a 26

percent fall in the purchasing power of US residents for UK goods and services.

• The difference in price changes resulted in a 2.6 percent gain in purchasing power of UK goods and services relative to US goods and services for US residents.

• Consequently, the 26 percent rise was offset by the 2.6 gain, resulting in an overall 24 percent loss in purchasing power.

Effective Exchange RateEffective Exchange Rate

A measure of the general value of a currency.

Page 32: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Effective Exchange Rate

• On any given day, a currency may appreciate in value relative to some currencies while depreciating in value against others.

• An effective exchange rate is a measure of the weighted-average value of a currency relative to a select group of currencies.

• Thus, it is a guide to the general value of the currency.

Page 33: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Weighted Average Value

• To construct an EER, we must first pick a set of currencies we are most interested in.

• Next, we must assign relative weights. In the following example, we weight the currency according to the country’s importance as a trading partner.

Page 34: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Weights

• Suppose that of all the trade of the US with Canada, Mexico, and the UK, Canada accounts for 50 percent, Mexico for 30 percent, and the UK for 20 percent.

• These constitute our weights (0.50, 0.30, and 0.20).

• Now consider the following exchange rate data.

£ 0.62 0.61

Page 36: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Calculating the EER• The EER is calculating by summing the

weighted values of the current period rate relative to the base year rate.

• The weighted-average value is calculated as:(weight i)(current exchange value i)/(base exchange value i)

where i represents each individual country included in the weighted average.

Page 37: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Calculating the EER

• Commonly this sum is multiplied by 100 to express the EER on a 100 basis.

• Hence, an EER is an index.

• As we shall see next, the base-year value of the index is 100.

• The index, therefore, is useful is showing changes in the weighted average value from one period to another.

Page 38: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Example

• Let last year be the base year.

• The effective exchange rate last year was:[(1.52/1.52)*0.50 + (10.19/10.19)*0.30

+ (0.61/.61)*0.20]*100

= 100.

• As with any index measure, the base year value is 100.

Page 39: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Example

• Today’s value of the EER is:(1.44/1.52)*0.50 + (9.56/10.19)*0.30

+ (0.62/0.61)*0.20

• or (0.958) 95.8

• The dollar, therefore, has experienced a 4.2 percent depreciation in weighted value.

Page 40: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Effective Exchange Measures

• There are a number of effective exchange measures available in the popular press. Some common measures are:

• Bank of England Index: The Economist.

• J.P. Morgan: The Wall Street Journal and the Financial Times.

Purchasing Power ParityPurchasing Power Parity

Page 43: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Purchasing Power ParityAbsolute or the Law of One Price

• Suppose The Economist magazine sells for £2.50 in the UK and $3.95 in the US.

• Arbitrage, therefore, should guarantee that the exchange rate between the dollar and the pound be s = 3.95/2.50 = 1.580 ($/£).

• In words, the dollar price of The Economist in the UK should equal the dollar price of the Economist in the US (ignoring transportation costs).

Page 44: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Absolute PPP

• Absolute PPP is expressed as P = P*×S, where P is the domestic price, P* is the foreign price, and S is the spot rate, expressed as domestic to foreign currency units.

• Often it is rearranged as: S = P/P*.

Page 45: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Absolute PPP as a Guide to Exchange Values

• Suppose the actual spot rate pertaining to the previous example is 1.7743 whereas PPP says the rate should be 1.580.

• A difference exists so we can conclude (for instructional purposes) that the pound is overvalued relative to the dollar.

• In percentage terms (1.580 - 1.7743) /1.7743 x 100 = -11 percent.

Page 46: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Relative PPP - A Weaker Version

• Rearrange APPP to S = P/P*.• Divide one period equation by another period, e.g.,

S1/S0= (P1/P0)/(P*1/P*0)

• Rearrange as: S1 = S0(P1/P0)/(P*1/P*0)

• Can be used as a “model” of exchange rate movements.

• Note that the emphasis is on exchange rate movements, not levels, though it may appear otherwise.

Page 47: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Example

• Suppose the exchange rate between the dollar and the pound was 1.58 in 2000 and is 1.77 today. Further, the UK CPI was 110 and is now 115, while the US CPI was 108 and is now 111.

• Plugging this into the formula we have• st = (1.58) [(111/108)/(115/110)] = 1.55• Hence the £ is overvalued (14%).

Page 48: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Another Expression

In words, domestic inflation less foreign inflation should equal the change in the spot rate.

Implies that the higher inflation country should see its currency depreciate.

Why Does Capital Flow?According to the optimal investment analysis...

Whenever returns are different in two countries.

According to the Balance of Payments Equation...

It doesn’t have much choice.

That is, it must flow into any country that is importing more than it is exporting.

How do we reconcile these two perspectives?

With changes in prices, returns, and exchange rates.

Page 99: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Key Points

1. MacDougall diagram can account for international investment in a frictionless world.

2. It produces Real Interest Parity, which says that when international capital markets are frictionless, real returns are equated across countries.

3. Capital will flow from capital-rich countries with ordinary returns to capital-poor countries with attractive possibilities.

4. MacDougall analysis can account for shocks to capital stock and technological shifts.

5. From a GNP standpoint, all countries benefit from international capital mobility.

Page 100: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Key Points

6. MacDougall analysis is highly simplified - only a benchmark from which to proceed.

7. Later in course we will introduce frictions (i.e. risk, taxes, government intervention, etc.).

8. The Balance of Payments equation tells us that goods and capital must flow together… or differences must be offset by government intervention (resulting in changes in reserve levels).

9. Not always clear whether goods drive capital or capital drives goods (i.e. are residents of one country demanding too much consumption or are foreigners too eager to invest).

10. Adjustments in prices, exchange rates, and returns will be important for balancing the balance of payments.

Central Bank Functions

• Fiscal Agents

• Bankers’ Bank

• Lenders of Last Resort

• Macroeconomic and Monetary Policy Makers– Exchange market intervention– Monetary policy

Page 105: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

The Monetary Base

• A nation’s monetary base can be measured by viewing either the assets or liabilities of the central bank.

• The assets are domestic credit (DC) and foreign exchange reserves (FER).

• The liabilities are currency in circulation (C) and total reserves of member banks (TR).

Money Stock

• There are a number of measures of a nation’s money stock (M).

• The narrowest measure is the sum of currency in circulation and the amount of transactions deposits (TD) in the banking system.

Page 108: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Money Multiplier

• Most nations require that a fraction of transactions deposits be held as reserves.

• The required fraction is determined by the reserve requirement (rr).

• This fraction determines the maximum change in the money stock that can result from a change in total reserves.

Page 109: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Money Multiplier

• Under the assumption that the monetary base is comprised of transactions deposits only, the multiplier is determined by the reserve requirement only.

• In this case, the money multiplier (m) is equal to 1 divided by the reserve requirement,

m = 1/rr.

Page 110: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Relating the Monetary Base and the Money Stock

• Under the assumptions above, we can write the money stock as the monetary base times the money multiplier.M = mMB = m(DC + FER) = m(C + TR).

• Focusing only on the asset measure of the monetary base, the change in the money stock is expressed as

M = m(DC + FER).

Page 111: The Spot Market for Foreign Exchange Market Characteristics: An Interbank Market The spot market is a market for immediate delivery 92 to 3 days). Primarily

Example - BOJ Intervention

• Suppose the Bank of Japan (BOJ) intervenes to strengthen the yen by selling ¥1 million of US dollar reserves to the private banking system.

• This action reduces the foreign exchange reserves and total reserves component of the BOJ’s balance sheet.

BOJ Intervention

• Because the monetary base declined, so will the money stock.

• Suppose the reserve requirement is 10 percent. The change in the money stock is

M = m(DC + FER),

M = (1/.10)(-¥1 million) = -¥10 million.

Exchange Rate Intervention

Why do governments attempt to fix exchange rates?

Why do governments attempt to fix prices?

1. They think ER volatility is destabilizing - that by removing volatility they will be making people better off.

2. Like any other price fix (i.e. U.S. sugar supports), ER fixes are a political tool. They subsidize one group at the expense of others.

3. To signal intentions.

How to Fix Exchange Rates

How can a government fix an exchange rate?

The same way a government fixes any other price:

1. By controls (much like U.S. price controls in early 1970s). Make trade at a different price illegal.

2. By intervention in the market (much like sugar). By committing to buy/sell at a certain price.

Example: The Uzbek Sum

In 1996, the Uzbek central bank fixed the exchange rate at an overvalued level of $0.02 / Sum:

• Imports were cheap; exports expensive; imports rose by 50% in 1996; exports were down.

• The central bank started running short of reserves.

• Daewoo and British American Tobacco experienced delays in converting Sum revenues.

• Black market exchange rate began falling steadily.

• In October, the Central bank canceled all conversion licenses and handed out dollar quotas.

Example: The Uzbek Sum

• The government banned the use of dollars inside Uzbekistan.

• Inflation soared.

• The black market rate fell to $0.0074 / Sum.

• Foreign investment inflows dried up - decreasing Sum demand further.
