Investing or saving? Why your savings account is costing you money

Greeks save, but mostly in deposits. That’s understandable after a decade of crises. The problem is that a deposit isn’t “safe”; it’s just predictably shrinking.

Inflation is a silent tax

If inflation is 3% and your deposit rate is 0.5%, you lose 2.5% of purchasing power a year. You don’t see it on the statement, since the number stays the same, but the same money buys less.

Over time the gap becomes enormous. €10,000 left in a deposit in 2005 has roughly €7,000 of purchasing power today. The same €10,000 in an internationally diversified equity portfolio would be, despite the crises, several times more.

What “investing” means

It doesn’t mean picking stocks or predicting the market. For most people it means:

• A global mutual fund that holds tiny pieces of thousands of companies around the world.
• Systematic, monthly contributions: say €150–€300 a month, regardless of what the market does.
• A long horizon, at least 7–10 years, so compounding works and the swings smooth out.

The role of time

Compounding means that returns produce further returns. €200 a month for 25 years is €60,000 in contributions. At a hypothetical average return of 7% a year, the final figure exceeds €160,000. Most of it was created by time, not by the money you put in.

That’s why the most important variable isn’t the “perfect” product choice, but how early you start.

The base first

Before you invest, make sure you have:

1. An emergency fund of 3–6 months’ expenses in a deposit.
2. The core risks covered (health; life, if people depend on you).

Once those exist, you don’t need to hold excess cash “just in case”, and the rest can work for you.

The risk is real

Markets fall. An equity portfolio can lose 20–30% in a bad year. Historically, though, over a ten-year horizon the sign has almost always been positive. The key is not to invest money you’ll need soon, and not to sell in a panic.
