International Money Transfers and Currency Markets

SWIFT System: Global private electronic messaging system facilitating communication between banks for money transfers. It's the primary mechanism for moving large sums of money internationally.
CHIPS (Clearing House Interbank Payments System): Facilitates dollar payments among banks by netting transactions, typically for amounts over \$3,000,000.
Fedwire: A domestic system handled by the U.S. Federal Reserve Bank, which can connect to international systems.
Correspondent Banks: Banks that act as agents for other banks, especially crucial in international business, vouching for them and assisting in transactions.

Currency Translation: Need to convert currencies, leading to exchange rate considerations.
Trust and Verification: Difficulty confirming receipt in foreign countries.
System Incompatibility: Domestic payment apps (e.g., Zelle, Cash App, Google Pay) generally don't work for international transfers.
Geopolitical Impact: Exclusion from systems like SWIFT can severely cripple a country's ability to conduct international trade (e.g., Russia's removal after the Ukraine invasion).

Currency Markets: Platforms for buying and selling foreign currencies.
Spot Rate: The exchange rate for immediate currency delivery, typically within two business days.
Currency Futures/Forward Rate: Contracts or agreements to buy or sell a specified amount of currency at a predetermined exchange rate for delivery on a fixed future date (e.g., 30, 60, 90, 100 days).
- Purpose: To hedge against future currency fluctuations and lock in favorable exchange rates, similar to commodity futures.
- Significance: Even small percentage changes (e.g., 1\% or 2\%) on large transactions (e.g., \$10,000,000) can result in substantial gains or losses.
Reciprocal Currencies: Quoted as dollars per unit of foreign currency.

Bid Price: The highest price a buyer is willing to pay for a currency.
Ask Price: The lowest price a seller is willing to accept for a currency.
Bid-Ask Spread: The difference between the bid and ask prices, representing the market's liquidity and cost of transaction.

Supply and Demand: Fundamental economic principle influencing exchange rates.
Interest Rates: Higher interest rates can attract foreign capital, increasing demand for a currency.
Capital Flow: The movement of money into and out of a country can significantly impact its currency's value (e.g., foreign debt, investment).
- A country's creditworthiness (e.g., national debt limit) directly affects its ability to borrow and the interest rates it must pay, impacting currency stability.
Monetary Policies: Actions by central banks to control the money supply (e.g., quantitative easing leading to inflation like the 9\% rate during COVID-19). Increasing money supply typically depreciates currency.
Fiscal Policies: Government decisions on taxation and spending, which also influence economic stability and currency value.

Law of One Price: In an efficient market, identical goods or financial instruments should trade at the same price when expressed in a common currency.
Arbitrage: The simultaneous purchase and sale of an asset in different markets to profit from a difference in its price, with no risk involved. This process tends to equalize prices across markets.
