Banking System

🏦 The Banking System: Your Money’s Neighborhood

Imagine a town where everyone helps each other with money…

🌟 The Big Picture

Think of banks like special houses in a neighborhood. Some houses help regular families save money and borrow for homes. Other houses help big businesses build skyscrapers. Together, they make the whole money-neighborhood work!

🏪 Commercial Banks: The Everyday Money Store

What Are They?

Commercial banks are like the friendly corner store for money. They’re open to everyone!

Simple Example:

• You have $100 from your birthday
• You put it in a piggy bank at the store (savings account)
• The store gives you a cookie ($1 interest) for letting them hold it
• Meanwhile, they lend your money to someone buying a bicycle

What They Do

Examples You Know:

• 🏦 Chase Bank
• 🏦 Bank of America
• 🏦 Wells Fargo

🏛️ Investment Banks: The Big Business Helpers

What Are They?

Investment banks are like special agents for really big deals. They don’t work with regular people - they help huge companies!

Simple Example: Imagine your lemonade stand grows HUGE:

• You want to open 100 stands across the city
• You need LOTS of money
• Investment bank says: “We’ll find people to buy tiny pieces of your company!”
• Now 1000 people each own a little piece of your lemonade empire

📊 Bank Balance Sheet: The Bank’s Report Card

What Is It?

A balance sheet is like a two-sided list showing everything a bank owns and owes.

Think of it like your toy inventory:

The Bank Version

graph LR
    subgraph Assets
    A["💵 Cash Reserves"]
    B["📄 Loans Given Out"]
    C["🏢 Buildings"]
    end
    subgraph Liabilities
    D["💰 Your Deposits"]
    E["🏦 Money Borrowed"]
    end
    subgraph Capital
    F[🛡️ Owner's Money]
    end

The Golden Rule:

Assets = Liabilities + Capital

If a bank has $100 in assets and owes $90, the owners put in $10 (capital). That $10 is the safety cushion!

💳 Bank Deposits and Loans: The Money Merry-Go-Round

Deposits: You Give, Bank Keeps

When you put money in a bank, you’re making a deposit. But here’s the magic - the bank doesn’t just stuff it in a vault!

Types of Deposits:

Loans: Bank Gives, You Return (Plus Extra!)

A loan is when the bank shares its money with you, but you promise to return MORE.

Example Story:

1. 🏦 Bank has $1000 from deposits
2. 🏠 You need $800 for a treehouse
3. 📝 Bank lends you $800
4. ⏰ You pay back $50 every month
5. 💰 After 18 months, you paid $900 total
6. 🎉 Bank earned $100 extra!

📈 Interest Rate Spread: The Bank’s Secret Sauce

What Is It?

The spread is the difference between what the bank PAYS you and what it CHARGES borrowers. This is how banks make money!

Super Simple Example:

You deposit $100 → Bank pays you 2% → You get $2/year

Bank lends $100 → Bank charges 6% → Bank gets $6/year

Bank's Profit = $6 - $2 = $4 💰

The Math Made Easy

graph LR
    A["🏦 Bank"] -->|Pays 2%| B["💰 Depositors"]
    C["🏠 Borrowers"] -->|Pay 6%| A
    A -->|Keeps 4%| D["📊 Profit!"]

Real World Numbers:

• Savings account pays: 0.5% to 4%
• Mortgage loan charges: 6% to 8%
• Credit card charges: 15% to 25%!

🛡️ Deposit Insurance: Your Money’s Bodyguard

What Is It?

Deposit insurance is like a safety net that catches your money if the bank falls!

The Story: Long ago, when banks failed, people lost EVERYTHING. Scary! So governments created insurance.

In the USA:

• 🏛️ FDIC (Federal Deposit Insurance Corporation)
• 💵 Protects up to $250,000 per person, per bank
• ✅ If bank crashes, you STILL get your money!

How It Works

    B -->|Yes, Under $250K| C["😊 FDIC Pays You Back!"]
    B -->|Over $250K| D["😟 Only Get $250K"]
    B -->|No Insurance| E["😭 Money Gone"]

Pro Tip: Spread big savings across multiple banks = more protection!

⚠️ Systemic Risk: When Everyone Gets Sick

What Is It?

Systemic risk is when one sick bank makes ALL banks sick. Like when one kid with a cold infects the whole classroom!

The Domino Story:

    A["🏦 Bank A Fails"] --> B["😰 Bank B Loses Money"]
    B --> C["🏦 Bank B Fails"]
    C --> D["😱 Bank C, D, E Panic"]
    D --> E["💥 Whole System Crashes!"]

The 2008 Example (Made Simple)

1. 🏠 Banks gave loans to people who couldn’t pay back
2. 📉 When they didn’t pay, banks lost money
3. 🏦 Big banks started failing
4. 😨 Everyone panicked - took money out
5. 🌍 Whole world economy got hurt!

Why It’s Scary

• Banks are connected like a spider web
• One breaking strand can collapse the whole web
• Government sometimes steps in to stop the dominos
