Subject 1. The Foreign Exchange Market PDF Download

An exchange rate is the current market price at which one currency can be exchanged for another. The convention used in the reading is the number of units of one currency (price currency) that one unit of another currency (base currency) will buy.

Let's say a:b = S.

  • a is the price currency.
  • b is the base currency.
  • S is the cost of one unit of currency b in terms of currency a.

For example, US$ : £ = 1.5 indicates that £1 is priced at US$1.5.

The exchange rate above is referred to as the nominal exchange rate. The real exchange rate is the nominal rate adjusted somehow by inflation measures.

For example, if country A has an inflation rate of 10%, country B an inflation rate of 5%, and no changes in the nominal exchange rate took place, then country A now has a currency whose real value is higher than before.

Market Functions and Participants

A foreign exchange market is a place where foreign exchange transactions take place. Measured by average daily turnover, the foreign exchange market is by far the largest financial market in the world. It has important effects, either directly or indirectly, on the pricing and flows in all other financial markets.

There is a wide diversity of global FX market participants that have a wide variety of motives for entering into foreign exchange transactions. Commercial companies undertake FX transactions during cross-border purchases and sales of goods and services. Hedge funds trade FX currencies for hedging or even speculative purposes. Central banks use their FX reserves to stabilize the market and control the money supply. Large dealing banks provide FX price quotes to their clients. With so many different market participants, motives, and strategies, it is very difficult to describe the FX market adequately with simple characterizations.

Exchange Rate Quotations

Most countries use a system of direct quotation. A direct exchange rate quote gives the home (domestic) currency price of a certain quantity of the foreign currency quoted (Domestic Currency/Foreign Currency, or DC/FC). In this case, the home currency is the price currency and the foreign currency is the base currency.

For example, the price of foreign currency is expressed in yen in Japan and pesos in Mexico. Direct quotation is used in most countries. For an American investor, a quote €:$ = 1.25 is a direct quote; he is expected to pay $1.25 for a €. Note that when there are two currencies, the base currency is always mentioned first, the opposite order of the actual ratio (price currency / base currency).

Indirect quotation (FC/DC) is also used in some markets. It is just the opposite of a direct quote; they are reciprocals of each other. For example, a bank in London will quote the value of the pound sterling (GBP) in terms of the foreign currency (i.e., £:$ = 1.4410).

Example

For a U.S. resident, ¥:$ = 0.0085 is the direct quote for Japanese yen and $:¥ = 119.46 is the indirect quote for Japanese yen.

In a direct quote, an appreciation of the foreign currency (a depreciation of the domestic currency) causes an increase in the direct quote.

  • The domestic currency moves in the opposite direction of the exchange rate.
  • The foreign currency moves in the same direction as the exchange rate.

The opposite is true for an indirect quote: the domestic (foreign) currency moves in the same (opposite) direction as the exchange rate.

Bid-Ask (Offer) Quotes and Spreads

Dealers (e.g., banks) do not normally charge a commission on their currency transactions but they profit from the spread between the buying and selling rates on both spot and forward transactions. Quotes are always in pairs: the first rate is the buy, or bid, price (for a dealer); the second is the sell, or ask, offer (for a dealer). The ask rate is usually higher than that bid rate, so the dealer can make a profit. The average of the bid and ask price is known as the midpoint price: midpoint price = (Ask + Bid) / 2.

When direct quotations are converted to indirect quotations, bid and ask quotes are reversed. That is:

  • The direct ask price is the reciprocal of the indirect bid price.
  • The direct bid price is the reciprocal of the indirect ask price.
  • No matter how the quote is made, dealers will always buy low and sell high.

For example, here is a direct quote for the Japanese yen from the U.S. perspective: ¥:$ = 0.0081-83. That is, the dealer is willing to buy ¥ at $0.0081 (direct bid price) and sell them at $0.0083 (direct ask price). The indirect bid price is (1/0.0083) $:¥ = 120.48 and the indirect ask price is (1/0.0081) = $:¥ = 123.45.

The bid-ask spread is the spread between bid and ask rates for a currency: Bid-ask spread = ask price - bid price. It is usually stated as a percentage of the ask price:

For example, with GBP quoted at £:$ = 1.4419 - 28, the percentage spread is: (1.4428 - 1.4419) x 100 / 1.4428 = 0.062%.

Note that the percentage spread is the same irrespective of whether the exchange rate is expressed in direct or indirect quotations.

The bid-ask spread is based on the breadth and depth of the market for that currency as well as on the currency's volatility.

ankurwa10 For an American investor, a quote €:$ = 1.25

Isn't it incorrect? Given what's stated below in the reading, the direct quote should be $:€ = 0.8 ??
birdperson what are the variables in the real exchange rate formula?
bergje11 Nominal exchange rate x domestic price / foreign price
santibanez I think it is the opposite. Nominal exchange rate*foreign price level/domestic price level where nominal exchange rate is defined as domestic currency units per unit of foreign currency, as in the reading and formula ($ per â
praj24 No, they're right.

US direct quote is â
fobucina The real exchange rate is defined as the nominal exchange rate x domestic price level / foreign price level if the the base currency is the domestic currency. Think of it this way - buying foreign goods will require one to convert to foreign currency. If the price of foreign goods increases faster than that of domestic goods, then the domestic currency's purchasing power drops
blank Remember: Direct quote... direct to you. How much it costs you. 1 yen costs you .0085 dlls
Vlz2103 Thanks blank. Currencies and I never got along.
kjw88 Hate the way CFA quote currencies, just seems so backwards - literally.
khalifa92 simpler explanation:

from US-based investor

Direct: USD(Domestic)/EUR(Foreign)= 1.2
Purchasing 1 euro (base) with 1.5 USD (price)
inDirect: EUR(Foreign)/USD(Domestic)= 0.8
You're purchasing your own currency (1) with 0.8 Euros
hanzrohm Fobucina is stating real exchange rate of foreign:domestic (read as domestic to foreign), it can also be (Nominal exchange rate D:F x foreign price level) / domestic price level, the real exchange rate of domestic:foreign (read as foreign to domestic).
