Spot Contract
Definition
1) A and B agree to trade on currency for another for delivery on the spot at a set price. 2) 90% of transactions
Term
Hedging/Speculation
Definition
Risking Reduction/Risk Taking
Term
Forwards
Definition
1) A and B agree to trade currencies at a set price on a settlement date. 2) Contract cannot be traded to third parties.
Term
Swaps
Definition
1) A and B agree to trade at a set price today and do reverse trade at a set price in the future. 2) Combine two contracts → a spot and a forward
Term
Options
Definition
- An agreement between a holder (buyer) and a writer (seller) that gives the holder the right, but not the obligation, to buy or sell foreign currency at a prearranged price, within a few days or a couple of years
- CALL OPTION: Gives the holder the right to buy foreign currency at a specified price
-PUT OPTION: Gives the holder the right to sell foreign currency at a specified price
- STRIKE PRICE: The price at which the option can be bought or sold at
Term
Option Example
Definition
EX. Suppose a U.S. importer is buying equipment from a German manufacturer with a € 1,000,000 payment due in 3 months. The importer can hedge against an euro appreciation by buying a call option that confers the right to purchase Euros over the next 3 months at a specific price.
Term
Futures
Definition
1) A and B agree to trade currencies at a set price in the future.
2) Can be traded to third parties.
Term
Arbitrage
Definition
Taking advantage of price differences in different markets. The purest form involves making a risk less profit through trading.
Term
Vehicle Currency
Definition
Most common is U.S. $
Term
Law of One Price (LOOP)
Definition
- Price of good g in europe over U.S. price = 1!
- If greater than 1, GOODS EXPENSIVE IN EU
Term
Purchasing Power Parity (PPP)
Definition
- Theory that overall price levels in each market must be the same
- Also called Absolute PPP
- Exchange rate = Relative Price Levels (Price EU/U.S.)
Term
Real Exchange Rate
Definition
- Relative price of basket is Eu vs. US = EU basket expressed in $ / Price of basket in US
- Tells us how many U.S. Baskets are needed to buy one European
Term
Real Appreciation
Definition
If the real exchange rate rises (less home goods needed in exchange for foreign goods)
Term
Overvalued
Definition
Foreign goods are relatively expensive so currency is overvalued by x%
Term
Relative PPP
Definition
Rate of depreciation of the nominal ER = Inflation Differential
Term
Speed of Price and Exchange Rate Convergence
Definition
1) 15% per year
2) 4 year half life
Term
Forecasting Exchange Rates
Definition
- Change in ER = Change in Real ER + (Inflation US - Inflation EU)
- When PPP holds, no change in Real ER so that terms = 0
Term
Forecasting Exchange Rates EXAMPLE
Definition
- You find that US inflation is 3%, Eurozone inflation is 2%
- Based on the inflation differential you predict a 1% rate of depreciation of the US dollar, or E to rise by 1%
- Then you also discover that the US dollar is 10% overvalued against the euro (q=0.90), relative to a PPP value of 1
- You expect 15% of that deviation of –0.1 to vanish in one year, so you expect q to rise (real depreciation) by 1.5%
- Adding the inflation differential, you now expect E to rise by 2.5%
Term
Big Mac Index
Definition
- Created by economist Pam Woodall
- Prices of big macs are consistently lower in developing countries than in developed
Term
Why are the deviations from PPP?
Definition
1) Transaction Costs
2) Non-Traded Goods
3) Imperfect Competition and Legal Obstacles
4) Price Stickiness
Term
Covered Interest Partiy (CIP)
Definition
- Investor covers the risk of the exchange rate changing in the future by using a forward contract
- RISKLESS ARBITRAGE
-
Term
Are there arbitrage profits?
Definition
We observed that once capital controls were removed, riskless arbitrage opportunities have disappeared
Term
Uncovered Interest Parity (UIP)
Definition
- Investor does not cover the risk and invests according to the current and expected future exchange rate
- RISKY ARBITRAGE
Term
Asset Approach to finding the interest rate on $ deposit
Definition
= Interest Rate on EU deposit + Expected Rate of Depreciation
Term
What Happens When We Increase Domestic Interest Rates?
Definition
E$/€ decreases (home currency appreciates)
Term
Carry Trade
Definition
- When UIP does not hold (home interest rate doesn't equal foreign plus interest), investors can earn profits from borrowing in one currency and investing in another
- = Int. R Foreign + Expected Depreciation Home Currency - Int. R Home
Term
Leverage and Margin Example
Definition
Example: You have $2,000 and borrow an additional $48,000 in yen from a bank in Japan.
- You have borrowed 25 times your own $2,000 capital, a leverage ratio of 25. You conduct carry trade, investing $50,000 in the Australian dollar.
- If you lose 4% on the trade, you’ve lost your initial capital investment. This initial capital put up by the investor of 4% of the total investment is known as a margin
Term
GNE (Gross National Expenditure)
Definition
- Total national spending on final goods and services
- = (C + I + G)
- In closed economy, GNE = GDP
Term
Trade Balance (net exports)
Definition
EX – IM
Term
GDP (Gross Domestic Product)
Definition
- Total value of goods and services produced
- GDP = GNE + TB = (C + I + G) + (EX – IM)
Term
Trade In Factor Services
Definition
- Occurs when one country is paid income by another, in compensation for labor, capital and land!
- A country exports factor services and receive factor income in return
-
Term
GNI (Gross National Income)
Definition
- Income earned by home factors only
- Subtract factor service imports and add factor service exports to GDP
- GNI = GDP + (EXFS – IMFS)
Term
GNDI (Gross National Disposable Income)
Definition
- Income available including transfers
- EX: Foreign aid, charity, income remittances by migrants to families back home
- GNDI = GNI + (UTin – Utout)
Term
Financial Account
Definition
- Cross-border movement (trade) in ownership of a financial claim
- FA = EXa – IMa = Asset Exports – Asset Imports
Term
Capital Account
Definition
- Transfer/receive assets as gifts
- KA = KAin – KAout
Term
National Income Identity
Definition
- GNDI = (C + I + G) + CA
- CA = TB + NFIA + NUT
- The sum of TB, NFIA and NUT is the difference between expenditure and income
-
Term
Trends For C, I and G
Definition
C = 70%
I = 15%
G = 15%
Term
When GNDI > GNE (C + I + G)...
Definition
CA > 0 → CA Surplus
Term
National Savings
Definition
= (GNDI – C - G)
- S = I + CA
- S is > 0 only if CA >0
Term
BOP Identity
Definition
= CA + KA + FA = 0
- If CA > 0, then KA + FA is < 0 and country is a net lender
- If CA < 0, then KA + FA is > 0 and country is a net borrower
