3Part I — The Money Warehouse: Foundations from Babylon
Chapter 3
Money should work, but not blindly
Inflation as a quiet thief, a buffer before investing, and the difference between investing and gambling. A first encounter with ETFs.
Money sitting idle isn't safe. It's slowly being eaten away. Inflation doesn't send notifications — a year from now, the same money will simply buy you less.
Worked example
What inflation does to savings
- Cash in a non-interest-bearing account
- 10,000 €
- Average inflation
- 4% a year
- Purchasing power after 10 years
- approx. 6,760 €
In nominal terms, you still have 10,000 €. In real terms, you've lost a third.
First the buffer, then the market
Before money starts working in the market, it needs support behind it. A safety buffer — three to six months of living expenses — is your load-bearing racking. Without it, every car breakdown or gap in employment will force you to sell investments at the worst possible moment.

What do I need a buffer for? I'd rather have it all growing on the stock market.

Because the stock market doesn't ask when you need money. It falls whenever it likes.
Investing versus gambling
The difference isn't in the instrument, but in the process. An investment has a rationale, a time horizon, an acceptable loss and an exit plan. Gambling has hope. The same shares can be either — depending on who's buying them and why.
For most people starting out in the market, broad-based index funds (ETFs) are a sensible foundation. They let you buy a small slice of hundreds or thousands of companies at once. You don't have to guess the winner — you buy the whole race.
