Credit (+)

Money flows into the country, such as through exports or foreign investments.

Debit (-)

Money flows out of the country, such as through imports or domestic investments abroad.

Current Account (CA)

Records transactions involving goods, services, and current transfers, measuring net trade.

Balance of Trade (Net Exports)

The difference between the value of exports and imports of goods and services.

Net Foreign Income

Income earned by domestic citizens from overseas assets minus income earned by foreigners from domestic assets.

Net Unilateral Transfers

One-way money transfers without goods or services in exchange, like foreign aid.

Financial Account (CFA)

Records the purchase and sale of financial and real assets.

Foreign Direct Investment (FDI)

Investment in real estate, factories, or businesses in another country.

Portfolio Investment

Purchasing stocks and bonds.

Official Reserves

Foreign currencies held by central banks.

Current Account Deficit

Occurs when imports exceed exports and must be financed by a financial account surplus.

Exchange Rate

The price of one currency in terms of another.

Appreciation

An increase in the value of a currency relative to another currency.

Depreciation

Demand Curve

Represents foreigners' desire to buy a country's currency to purchase goods or assets.

Supply Curve

Represents citizens selling their currency to purchase foreign goods.

T.I.P.S.

A mnemonic for the major factors affecting currency demand and supply: Tastes, Income, Price level, Speculation.

Tastes and Preferences

If consumers prefer goods from a specific country, demand for that country's currency increases.

Relative Income Levels

When a country's GDP rises, their currency typically depreciates due to increased imports.

Relative Inflation

If one country experiences high inflation compared to another, its currency will depreciate.

Speculation (Interest Rates)

Financial capital flows to the country with the highest real interest rates, affecting demand for its currency.

Net Exports ($X-M$)

The difference between a country's exports and imports, affected by currency fluctuations.

Common Mistake: Capital Definitions

In GDP, 'Capital' refers to physical tools; in BoP, it refers to financial assets.

Common Mistake: Income Trap

Higher income levels can lead to currency depreciation due to increased imports.

Common Mistake: Double Shifting

On the AP exam, usually only shift one curve on graphs unless specified.

Labeling Axes Incorrectly

For Forex graphs, specify the ratio on the Y-axis (e.g., Yen/Dollar) instead of just 'Price'.
