Chapter 4: International Flow of Funds and Exchange Rates

Vocabulary terms and direct definitions covering the Balance of International Payments, components of the foreign exchange market, exchange rate regimes, international monetary agreements, and parity theories.

Balance of payments (BOP)

A statement of account that summarizes all transactions between the residents of one country and the rest of the world for a given period of time, usually one year.

Double-entry accounting

An accounting framework in which each transaction is recorded as two entries so that the sum of credits equals the sum of debits, ensuring that the BOP must always balance.

Current account

The primary BOP account driven by consumers, businesses, and government entities, consisting of the balance of trade in goods, balance of trade in services, balance of primary income, and balance of secondary income.

Balance of trade in goods

The net calculation of merchandise exports (dollars entering a country, recorded as credits) minus merchandise imports (dollars leaving a country, recorded as debits).

Trade deficit

A condition that occurs when a nation's merchandise imports exceed its merchandise exports.

Capital surplus country

A country that runs a current account surplus and consequently invests its excess funds or savings abroad.

Capital account

A BOP account documenting credit and debit entries for non-produced nonfinancial assets and capital transfers between residents and nonresidents.

Capital account balance

The net total of transactions involving non-produced nonfinancial assets and unilateral capital transfers; generally the least significant and smallest component in a country's BOP.

Financial account

The BOP account documenting the net acquisition and disposal of financial assets and liabilities, measuring how net lending or borrowing with nonresidents is financed.

Foreign direct investment (FDI)

Cross-border investment wherein an investor resident in one economy gains control or a significant degree of influence over the management of an enterprise resident in another economy.

Portfolio investment

Cross-border transactions and positions involving debt or equity securities, excluding those direct investments categorized under FDI.

Net errors and omissions

A balancing item reported in BOP data to reconcile statistical discrepancies arising from timing differences and unrecorded or illegal trade, approximately equal to the financial account balance minus the sum of the current and capital account balances.

Reserve assets

External foreign currency assets readily available to and controlled by monetary authorities to meet BOP financing needs, intervene in foreign exchange markets, and sustain confidence in the national currency.

Foreign exchange markets (forex)

A continuous global telecommunications network of commercial banks, currency traders, speculators, and central banks facilitating the exchange of currencies, with daily trading exceeding $5\text{ trillion}$.

Exchange rate

The price of one country's currency expressed in terms of another currency.

Independent floating exchange rate system

An exchange rate regime where currency values are determined freely by market demand and supply without central bank pegs or targets.

Managed floating exchange rate system

An exchange rate regime where market forces primarily set currency values, but central banks actively intervene by buying or selling reserves to limit excessive fluctuations.

Fixed exchange rate system

An exchange rate regime where a nation formally or informally anchors its currency to a major foreign currency or basket of currencies, permitting only narrow margins of fluctuation around a central rate.

Spot market

The foreign exchange market segment where currency transactions are executed on a real-time basis for immediate delivery.

Bid-ask spread

The difference between the ask (sell) price and the bid (buy) price quoted by financial institutions, representing the bank's fee or profit margin on a currency transaction.

Direct quote

A foreign exchange rate quotation stated as the domestic currency price of one unit of foreign currency ($\text{domestic/foreign}$).

Indirect quote

A foreign exchange rate quotation stated as the foreign currency units obtainable per one unit of domestic currency ($\text{foreign/domestic}$), serving as the reciprocal of a direct quote.

Forward market

An over-the-counter market where market participants agree to purchase or sell currencies at a specified exchange rate on a fixed future date.

Forward rate

The agreed-upon exchange rate locked in today for a currency delivery scheduled to occur on a specified date in the future.

Discount

A condition occurring when a currency's forward exchange rate is lower than its spot rate, indicating expected depreciation relative to another currency.

Premium

A condition occurring when a currency's forward exchange rate is higher than its spot rate, indicating expected appreciation relative to another currency.

Hedge

A risk management strategy that uses forward contracts or other derivative instruments to lock in exchange rates and minimize potential losses from currency volatility.

International monetary system

The structural and institutional framework that establishes rules for international payments, governs cross-border capital flows, and determines exchange rates.

Smithsonian Agreement

A December 1971 multinational pact in which the U.S. devalued the dollar against other currencies, Germany floated the Deutsche mark, and the IMF established central rates with widened margins of $\pm 2.25\%$.

Jamaica Agreement

A January 1976 agreement establishing a flexible monetary order where IMF members could select their own exchange regimes, gold was demonetized, and the SDR was designated as the primary reserve asset.

Special drawing right (SDR)

An international reserve asset created by the IMF in 1969 whose value is determined daily by a weighted basket of five major currencies: U.S. dollar, euro, Chinese yuan, Japanese yen, and British pound.

Clean float currency

A currency whose exchange rate fluctuates freely based purely on market supply and demand with little to no central bank intervention.

Dirty float currency

A currency regime characterized by frequent and active central bank interventions to manage currency value within an acceptable range.

Dollarization

The formal or informal adoption of the U.S. dollar or another stable foreign currency to circulate as legal tender alongside or in place of a country's domestic currency.

Hard currencies

Highly liquid, stable, and widely traded currencies that can be readily converted into any other currency globally.

Soft currencies

Illiquid and unstable currencies of developing or emerging economies, frequently pegged to hard currencies to promote domestic financial and price stability.

Arbitrage

The simultaneous purchase and sale of identical assets or currencies in different markets to exploit price discrepancies and lock in a risk-free profit until prices converge.

Law of one price

The economic proposition that in competitive, friction-free markets, identical goods must sell for equivalent prices across different countries when converted into a common currency.

Purchasing power parity (PPP)

An exchange rate theory based on the law of one price which states that exchange rates between currencies are in equilibrium when identical baskets of goods cost the same in both countries.

Big Mac Index

An informal purchasing power parity benchmark published by The Economist since 1986 that evaluates currency valuation by comparing local prices of a standardized McDonald's Big Mac.

Interest rate parity (IRP)

A financial condition stating that interest rate differentials between two nations should equal the percentage difference between the forward exchange rate and the spot exchange rate, preventing risk-free arbitrage.

Covered interest rate parity

An exchange condition where forward contracts eliminate foreign exchange risk, mathematically equalizing interest rate spreads with forward exchange rate premiums or discounts: $(1 + i_{US}) = \left(\frac{F}{S}\right)(1 + i_E)$.

Uncovered interest rate parity

A parity relationship asserting that interest rate differentials between countries equal the expected change in future spot rates, assuming investors require no risk premium.

Risk premium

The extra expected return required by risk-averse investors to hold foreign or risky debt securities rather than riskless domestic assets.
