Key Concepts

Habari Mwanafunzi! Let's Talk About Money!

Ever stopped to think about that 100 bob note in your pocket? It's just a piece of paper (or polymer, to be exact!), but you can use it to buy a soda and a smokie, pay your matatu fare, or even save it for something bigger. How does a simple piece of paper get all this power? Welcome to the fascinating world of Money and Banking! Today, we are going to unlock the big ideas, the Key Concepts, that make our economy tick. By the end of this lesson, you'll look at money in a whole new way!

1. Back to Basics: Barter Trade

Before we had the Kenyan Shilling, how did people trade? They used barter trade, which is simply exchanging goods and services directly for other goods and services.

Imagine a Maasai herder in Kajiado who has many cows but needs maize. He travels to meet a Kikuyu farmer in Kinangop who has plenty of maize but wants a cow for a ceremony. If they agree, they can trade one cow for, say, ten sacks of maize. That's barter trade in action!

But, this system had some major problems:

• Double Coincidence of Wants: Both people had to want exactly what the other person had. What if the farmer wanted goats, not a cow? The trade wouldn't happen!
• Lack of a Standard Measure of Value: How do you decide how many sacks of maize one cow is worth? Is it 10? 15? It was hard to set a fair price.
• Indivisibility of Goods: You can't pay for a loaf of bread with a leg of a live cow! Many goods couldn't be divided into smaller units.
• Difficulty in Storing Wealth: Storing wealth meant storing actual goods. Your maize could get eaten by weevils, and your cow could get sick.

2. The Superstar Arrives: Money!

Because of the problems with barter, people created money. Money is anything that is generally accepted by a community as a medium of exchange for goods and services.

For something to be good money, it needs these characteristics:

• Durable: It must last a long time. Our new polymer notes are much more durable than the old paper ones.
• Acceptable: Everyone in Kenya agrees to accept the Shilling as payment.
• Divisible: It can be broken down into smaller values (e.g., a 1000 Shilling note can be broken into 500s, 200s, 100s, and coins).
• Portable: It must be easy to carry. It's much easier to carry 10,000 KES in your pocket than to carry the goat it's worth!
• Scarce: It must have a limited supply, controlled by the Central Bank of Kenya (CBK), to maintain its value.
• Homogeneous: All units of the same value must be identical. Every 50 bob coin looks and feels the same.

3. Supply & Demand: The Tug-of-War for Money

Just like with tomatoes at the market, there is a demand for and a supply of money. The Central Bank of Kenya (CBK) is in charge of the supply, while we, the people and businesses, create the demand.

Why do we demand (want to hold) money?

• Transaction Motive: To pay for everyday things - your fare, lunch, airtime.
• Precautionary Motive: To save for emergencies - what if you fall sick or your phone breaks?
• Speculative Motive: To invest and make more money, like buying shares or starting a small side hustle.

4. The Value Thief: Inflation

Have you ever heard your parents say, "Back in my day, a bottle of soda was only 5 shillings!"? What happened? The answer is inflation.

Inflation is the rate at which the general level of prices for goods and services is rising, and as a result, the purchasing power of money is falling. In simple terms, your 100 bob buys you less today than it did last year.

Let's calculate a simple inflation rate for a loaf of bread:

    Formula:
    Inflation Rate = ((Current Price - Old Price) / Old Price) * 100%

    Example:
    Price of bread last year = 55 KES
    Price of bread this year = 65 KES

    Calculation:
    = ((65 - 55) / 55) * 100%
    = (10 / 55) * 100%
    = 0.1818 * 100%
    = 18.18%

    So, the price of bread inflated by about 18.18% in one year!

5. The Money Middlemen: Financial Intermediaries

Where do you keep your money safe? A bank! A bank is a type of financial intermediary. These are institutions that act as a bridge between those who have surplus money (savers) and those who need money (borrowers).

The main players in Kenya are:

• Commercial Banks: Like KCB, Equity, Co-operative Bank.
• SACCOs (Savings and Credit Co-operative societies): Very popular for saving and getting loans with good rates.
• Microfinance Institutions: They provide small loans, like to a mama mboga expanding her kiosk.
• Mobile Money Services: M-Pesa is a perfect Kenyan example! It connects millions of people financially.

    // How Intermediaries Work

    [SAVER with extra money] --- deposits money ---> [BANK / SACCO] --- gives loan ---> [BORROWER who needs money]
                                      ^                                                   |
                                      |                                                   |
                                   (Pays small interest to saver)      (Charges higher interest to borrower)

6. The Price of a Loan: Credit & Interest

When you borrow money, you are using credit. This is an agreement where you receive money now and promise to pay it back later.

But you always have to pay back more than you borrowed. That extra amount is called interest. Interest is the cost of borrowing money. It's also the reward you get for saving your money in a bank!

Let's say your older brother wants to buy a new boda boda for his business. It costs 80,000 KES. He gets a one-year loan from a SACCO. The SACCO tells him the interest rate is 12% per year. How much interest will he pay?

We can calculate this using the Simple Interest formula.

    Formula:
    Simple Interest (I) = Principal (P) x Rate (R) x Time (T)

    Where:
    P = The amount of the loan (80,000 KES)
    R = The annual interest rate (12% or 0.12)
    T = The time in years (1 year)

    Calculation:
    I = 80,000 * 0.12 * 1
    I = 9,600 KES

    So, your brother will pay 9,600 KES in interest for the loan. The total amount he will repay is 80,000 + 9,600 = 89,600 KES.

Great job for making it this far! You've just learned the core ideas that control how money works in Kenya and all over the world. From simple barter trade to complex bank loans, you now have the knowledge to understand the financial world around you. Keep asking questions and stay curious!
