Market Risk Fundamentals 🎢
Imagine you’re on a roller coaster. Sometimes it goes up, sometimes it zooms down. You never know exactly what’s coming next. That’s what market risk feels like for banks and investors!
The Big Picture: What is Market Risk?
Market risk is the chance that you might lose money because prices in the market go up or down.
Think of it like this: You buy a toy for $10 today. Tomorrow, everyone wants that toy, so it’s worth $15! Great news! But wait… the day after, a newer toy comes out, and your toy is only worth $5 now. 😱
That’s market risk in action.
Banks and big companies face this every single day with:
- 💵 Money from different countries (currencies)
- 📈 Company stocks (equity)
- ⛽ Things like oil, gold, and wheat (commodities)
Value at Risk (VaR) 📊
The “How Much Could I Lose?” Question
VaR is like a weather forecast, but for money!
Simple Example:
A bank says: “Our VaR is $1 million at 95% confidence for one day.”
What does this mean?
🌤️ “On 95 out of 100 normal days, we won’t lose more than $1 million.”
But remember — on 5 of those 100 days, we MIGHT lose more!
How VaR Works (The Ice Cream Shop Story)
Imagine you own an ice cream shop.
| Day | Sales |
|---|---|
| Monday | $100 |
| Tuesday | $80 |
| Wednesday | $150 |
| Thursday | $70 |
| Friday | $200 |
You look at your worst days. Your VaR tells you: “On a bad day, expect to make only $70-$80.”

Real Bank Example: A bank holds $100 million in investments. Their VaR analysis shows:
- 95% of the time, daily loss won’t exceed $2 million
- They keep extra cash ready just in case!
Currency Risk 💱
When Money Changes Its Mind
You know how 1 apple doesn’t always cost the same at different stores? The same happens with money from different countries!
Story Time:
Little Emma from the USA wants to buy a toy from Japan. The toy costs 1,000 Japanese Yen.
| When | Exchange Rate | Cost in USD |
|---|---|---|
| January | 1 USD = 100 Yen | $10 |
| February | 1 USD = 80 Yen | $12.50 |
| March | 1 USD = 125 Yen | $8 |
The toy’s Japanese price never changed! But Emma pays different amounts because currency values move like waves.
Real-World Impact
Example: A US Company Sells Cars in Europe
The company sells a car for €20,000 in Germany.
graph TD A["Sell Car: €20,000"] --> B{Exchange Rate?} B -->|1 EUR = 1.10 USD| C["Receive $22,000"] B -->|1 EUR = 0.90 USD| D["Receive $18,000"] C --> E["Happy! 😊"] D --> F["Ouch! 😟"]
$4,000 difference — just because of currency movement!
Equity Risk 📉📈
The Stock Market Roller Coaster
When you buy a piece of a company (called a “stock” or “share”), you become a tiny owner!
But here’s the catch: The price changes EVERY DAY based on:
- 📰 News about the company
- 🌍 What’s happening in the world
- 😊😟 How people FEEL about the future
The Lemonade Stand Story
You buy a share in your friend’s lemonade stand for $10.
| Event | What Happens to Your $10 Share? |
|---|---|
| ☀️ Sunny week forecast | Price goes UP to $12 |
| 🌧️ Rainy week forecast | Price goes DOWN to $7 |
| 🍋 Lemon shortage | Price DROPS to $5 |
| 🏆 Stand wins “Best Lemonade” award | Price JUMPS to $15 |
None of these changed how good the lemonade tastes! But people’s expectations changed the price.
Two Types of Equity Risk
-
Company-Specific Risk: Only affects ONE company
- Example: The CEO quits suddenly
-
Market-Wide Risk: Affects EVERYONE
- Example: A recession hits the whole country
Commodity Risk ⛽🌾💎
Stuff From the Earth
Commodities are real, physical things:
- 🛢️ Oil and gas
- 🥇 Gold and silver
- 🌾 Wheat and corn
- ☕ Coffee and cocoa
Why Prices Go Crazy
The Orange Juice Story:
Imagine Florida grows most of America’s oranges.
| Scenario | What Happens to OJ Prices? |
|---|---|
| Perfect sunny weather | Prices stay LOW ⬇️ |
| Frost destroys 40% of oranges | Prices SPIKE UP ⬆️⬆️⬆️ |
| Scientists create twice-as-fast-growing oranges | Prices DROP ⬇️⬇️ |
Real Example: Oil Prices
graph TD A["World Events"] --> B{Oil Supply & Demand} B --> C["War in Oil-Producing Country"] B --> D["New Electric Cars = Less Oil Needed"] B --> E["Cold Winter = More Heating Oil"] C --> F["Price Goes UP"] D --> G["Price Goes DOWN"] E --> F
Banks that lend to oil companies worry: “What if oil prices crash and they can’t pay us back?”
Basis Risk 🎯
When Your Shield Has a Hole
Basis risk happens when your protection doesn’t match your problem perfectly.
The Umbrella Story
Imagine you’re worried about rain, so you buy an umbrella. But…
| Your Problem | Your Protection | The Gap (Basis Risk) |
|---|---|---|
| Heavy rain in YOUR city | Weather forecast for ANOTHER city | Forecasts don’t match! |
| Rain at 3 PM | Umbrella only works till 2 PM | Timing doesn’t match! |
Real Banking Example
A bank owns shares in Small Tech Company ABC.
They want protection, so they buy insurance tied to the Big Tech Index (like all tech companies together).
Problem: Small Tech ABC doesn’t move exactly like the Big Tech Index!
| Day | Big Tech Index | Small Tech ABC | Mismatch? |
|---|---|---|---|
| Mon | -2% | -5% | ❌ YES |
| Tue | +1% | +3% | ❌ YES |
| Wed | -1% | -1% | ✅ Perfect! |
graph TD A["You Own: Apple Stock"] --> B["You Buy Protection For: All Fruit Index"] B --> C{Do They Move Together?} C -->|Not Always!| D["BASIS RISK EXISTS"] C -->|Yes, Always| E["No Basis Risk"]
The gap between what you own and what you’re protected for = Basis Risk
Market Risk Hedging 🛡️
Building Your Financial Shield
Hedging = Making a backup plan so you don’t lose too much money.
Think of it like wearing a helmet when you ride a bike. You hope you won’t fall, but if you do — you’re protected!
Common Hedging Tools
| Tool | How It Works | Example |
|---|---|---|
| Forward Contract | Lock in a future price TODAY | “I’ll buy wheat in 3 months at $5/bushel no matter what” |
| Options | Pay a small fee for the RIGHT (not obligation) to buy/sell | Like a reservation at a restaurant |
| Swaps | Trade one type of payment for another | Exchange fixed payments for variable ones |
The Farmer’s Smart Move
Problem: Farmer Sarah grows wheat. She worries prices will drop before harvest.
Solution: She signs a Forward Contract
| Scenario | Without Hedge | With Hedge |
|---|---|---|
| Wheat price FALLS to $4 | Sarah gets $4 😟 | Sarah still gets $5 🛡️ |
| Wheat price RISES to $6 | Sarah gets $6 😊 | Sarah still gets $5 (missed the extra!) |
Trade-off: Hedging protects from bad outcomes but might limit great outcomes!

Putting It All Together 🧩
Banks face market risk from many directions at once:

Quick Summary
| Risk Type | What Could Change? | Example |
|---|---|---|
| Currency | Exchange rates | USD vs EUR moves |
| Equity | Stock prices | Apple stock drops 10% |
| Commodity | Physical goods prices | Oil spikes due to war |
| Basis | Gap between hedge and actual | Your protection doesn’t match |
The Golden Rule
🌟 You can’t eliminate market risk, but you can MEASURE it (VaR) and MANAGE it (hedging)!
Remember This! 🧠
Market Risk = The chance that market prices move against you
Like that roller coaster we talked about at the start:
- VaR tells you how scary the drop might be
- Hedging is your safety harness
- But sometimes the harness doesn’t fit perfectly (basis risk!)
You’re now ready to think like a risk manager! 🎉
