Saving money protects you from emergencies. Investing grows your money into more money. They are different actions with different purposes, and both are necessary. When you invest, you put money to work so that it produces a return — interest, dividends, or capital growth — without you working for it directly. The three investment options most accessible to young Nigerians are Treasury Bills, money market funds, and the stock market. Treasury Bills are government-issued instruments that pay a fixed return over a short period — currently around 18-22% annually in Nigeria. They are considered low risk because the government guarantees them. Money market funds pool your money with other investors and invest it in short-term instruments — they are accessible through apps like Cowrywise and Risevest and typically yield 12-18% annually. The stock market offers higher potential returns but with higher volatility — the value of shares goes up and down with company and market performance. Starting with Treasury Bills or a money market fund is sensible for a first investor because the returns are predictable and the risk is low. The principle to understand is: money sitting idle in a current account earns nothing. Inflation erodes it. Invested money grows. The earlier you start, the more time your money has to compound.
