Foreign Exchange

🌍 Global Markets: Foreign Exchange

The World’s Biggest Money Swap Meet!

Imagine a giant marketplace where people from every country come to trade their money. You have dollars, your friend has euros, another friend has yen. Everyone needs to swap their money to buy things from other countries. That’s the Foreign Exchange Market—the biggest swap meet in the world!

🏪 The Forex Market

What Is It?

The Forex Market (short for Foreign Exchange) is like a massive online store that never closes. It’s open 24 hours a day, 5 days a week. People, banks, and countries trade money here.

Think of it like this: You have a lemonade stand. A kid from Japan wants your lemonade but only has yen. You only take dollars. The Forex market helps you swap yen for dollars!

How Big Is It?

• Over $7 trillion traded every day
• That’s more than all stock markets combined!
• It connects every country on Earth

💑 Currency Pairs

Always a Dance Partner

Currencies never dance alone! They always come in pairs. When you buy one currency, you automatically sell another.

Example: EUR/USD = Euro and US Dollar

• The first currency (EUR) = Base Currency (what you’re buying)
• The second currency (USD) = Quote Currency (what you’re paying with)

Common Currency Pairs

Simple Example: If EUR/USD = 1.10, it means 1 Euro costs 1.10 US Dollars

💱 Exchange Rates

The Price Tag on Money

An exchange rate tells you how much one currency costs in another currency. It’s like a price tag, but for money!

How Does It Work?

• USD/INR = 83 means 1 Dollar = 83 Indian Rupees
• EUR/USD = 1.10 means 1 Euro = 1.10 US Dollars

graph TD
    A["You Have: $100"] --> B{Exchange Rate}
    B --> C["USD/EUR = 0.91"]
    C --> D["You Get: €91"]

Why Rates Change

Exchange rates go up and down like a seesaw. They change because of:

• How strong a country’s economy is
• What the government decides
• How much people want that currency

⚡ Spot Rate

Right Here, Right Now!

The Spot Rate is the price to swap currencies immediately—like buying candy at the store. You pay now, you get your candy now!

Key Points

• Settlement happens in 2 business days (called T+2)
• It’s the “real-time” price you see on screens
• Used for quick, everyday transactions

Example: Today’s spot rate for EUR/USD is 1.0950. If you want euros right now, this is what you’ll pay!

📅 Forward Rate

Booking Today for Tomorrow

The Forward Rate is like making a reservation. You agree on a price TODAY, but the actual swap happens in the FUTURE.

Why Use It?

Imagine you’re a toy company. In 3 months, you need to pay a Japanese supplier in yen. But what if the yen gets more expensive?

Forward Rate to the rescue! You lock in today’s price for 3 months from now.

Spot vs Forward

📈📉 Currency Value Changes

Why Money Gets Stronger or Weaker

Currencies are like popularity contests. Sometimes a currency is “cool” and everyone wants it (it gets stronger). Sometimes it’s not (it gets weaker).

Appreciation vs Depreciation

• Appreciation = Currency gets stronger (buys more)
• Depreciation = Currency gets weaker (buys less)

Example:

• Last year: $1 = €0.85
• This year: $1 = €0.91
• The dollar appreciated (got stronger)!

What Causes Changes?

🍔 Purchasing Power Parity (PPP)

The Big Mac Theory

Purchasing Power Parity says that the same thing should cost the same everywhere—when you convert currencies.

The Famous Big Mac Index

The Economist magazine uses Big Mac prices to check if currencies are “fair.”

Example:

• Big Mac in USA = $5.50
• Big Mac in UK = £3.50
• If £1 = $1.57, then UK Big Mac = $5.50
• Prices match! The exchange rate is “fair.”

graph TD
    A["Big Mac USA: $5.50"] --> B{Should Equal}
    C["Big Mac UK: £3.50"] --> B
    B --> D["Fair Exchange Rate"]
    D --> E["£1 = $1.57"]

The Simple Rule

If a burger costs way more in one country, that currency might be overvalued. If it costs way less, the currency might be undervalued.

💰 Interest Rate Parity (IRP)

The Fair Play Rule for Banks

Interest Rate Parity is like a rule that says: “No easy free money from currency tricks!”

How It Works

Imagine two countries:

• Country A pays 5% interest on savings
• Country B pays 2% interest on savings

You might think: “I’ll put my money in Country A and earn more!”

But wait! The exchange rate will adjust to make both choices equal.

The Magic Formula

The currency with higher interest rates will be cheaper in the future (forward rate).

Example:

• US interest rate: 5%
• Japan interest rate: 0.5%
• US forward rate will be LOWER than spot rate
• Japan forward rate will be HIGHER than spot rate

    A["High Interest Rate Country"] --> B["Currency Depreciates Forward"]
    C["Low Interest Rate Country"] --> D["Currency Appreciates Forward"]
    B --> E["Both Give Same Return!"]
    D --> E

Why It Matters

Interest Rate Parity prevents people from making “risk-free” profits by just moving money between countries. The forward rate adjusts to balance everything out!

🎯 Quick Summary

🌟 You’ve Got This!

Foreign exchange might seem complex, but remember:

1. It’s just swapping money between countries
2. Rates change based on supply and demand
3. Forward contracts help protect against surprises
4. PPP and IRP keep things balanced

Now you understand how the world trades money! 🎉
