€45,000. Gone Without Doing Anything

You have €100,000 in your current account. You do not touch it, invest it or move it. You leave it there, safe. Or so you think.

After 10 years, those €100,000 are worth approximately €82,000 in real terms. After 20 years, €67,000. After 30 years, €55,000.

You have not spent a cent. You have not experienced a market crash. You have not signed a bad contract. And yet you have lost €45,000. Almost half of your wealth, evaporated silently.

The culprit has a name: inflation. And its accomplice has an even more familiar name: the current account.

Welcome to the most expensive paradox in personal finance: the one in which the choice that seems safest is actually the only one that guarantees a certain loss.

Italy’s Most Expensive Investment Is Called “Not Investing”

Italy is a country that keeps its money under the mattress. Not literally—although some people still do—but the result is the same. According to Bank of Italy data, Italians hold approximately €1.8 trillion sitting idle in current accounts. One thousand eight hundred billion euros. A figure that dwarfs the GDP of many European countries.

And this €1.8 trillion is not earning zero. It is earning less than zero. Because a current account that yields 0% in a world with annual inflation of 2–3% is an instrument that destroys wealth. Every day. Every month. Every year.

The mechanism is as simple as it is devastating: if one kilogram of bread costs €4 today and inflation is 2%, it will cost €4.08 in a year. Your €100,000 in the account buys a certain quantity of goods and services today. In a year, it will buy slightly less. In ten years, significantly less. In thirty years, almost half as much.

It is not an opinion. It is arithmetic.

But why, then, do so many people—intelligent, informed and rational people—consciously choose to keep enormous sums in their current accounts?

The answer is simple: because inflation is invisible. And the human brain is programmed to fear what it sees, not what it does not see.

The Figures Behind the Silent Erosion

Let us let the numbers speak. Numbers have no opinions, do not sell products and do not try to make you feel guilty.

The Purchasing Power That Disappears

€100,000 in a current account yielding 0%, with average annual inflation of 2%—the ECB’s stated target, so not a pessimistic scenario but an objective:

Years elapsed	Nominal value	Real purchasing power	Real loss
5 years	€100,000	€90,573	-€9,427
10 years	€100,000	€82,035	-€17,965
15 years	€100,000	€74,301	-€25,699
20 years	€100,000	€67,297	-€32,703
25 years	€100,000	€60,953	-€39,047
30 years	€100,000	€55,207	-€44,793

Read the last row again. After 30 years, those €100,000 buy goods worth the equivalent of €55,207 today. You have lost almost €45,000 in purchasing power. Without doing anything at all.

And if average inflation were 3%—something we have significantly exceeded in recent years—the picture becomes drastically worse: after 20 years, purchasing power falls to approximately €55,000. After 30 years, to €41,000. More than half of your wealth, dissolved.

(The remarkable thing is that your bank statement will still show €100,000. The number does not change. And that makes it the perfect theft: money is taken from your pocket without your wallet appearing any lighter.)

The Comparison That Hurts

Now let us place those figures next to an alternative. Not a speculative investment, not a bet on cryptocurrencies or individual stocks. A globally diversified portfolio with a real return—that is, already net of inflation—of 5% per year. A figure consistent with the historical average of global equity markets over long-term horizons.

Scenario: €100,000, 20-year horizon.

Strategy	Value after 20 years (in real purchasing power)
Current account (0% real return, 2% inflation)	€67,297
Diversified portfolio (5% real return)	€265,330
Difference	€198,033

One hundred and ninety-eight thousand euros. This is not the return on an investment. It is the cost of not having invested. The difference between doing something and doing nothing. Between allowing time to work for you and allowing it to work against you.

If you think the figure is exaggerated, it is only because you do not yet fully understand the mechanism of compound interest. Compounding is the same force that erodes your purchasing power when you remain idle; when you put it to work in the markets, however, it works in your favour.

The Safety Paradox

Here is the point no one explains at the bank counter: not investing is not a neutral option. It is not “doing nothing.” It is an active choice to lose money.

The investor who keeps everything in a current account believes they are taking no risks. In reality, they are taking the only risk with a guaranteed outcome: the certain loss of purchasing power. And they take it every single day.

Someone who invests in a diversified portfolio takes the risk of volatility: markets rise, fall and cause concern. But over the long term, the probability of a positive real return has historically been very high. Someone who does not invest takes the risk of inflation, which does not rise and fall, make noise or generate newspaper headlines. It simply eats your money. Every year. With mathematical certainty.

Volatility is a visible risk. Inflation is an invisible risk. And we—brilliant but biologically short-sighted human beings—fear what we see and ignore what we do not see.

And so the current account becomes the most expensive investment there is. Not because it is inherently wrong, but because it is used for purposes for which it was never designed: parking wealth for years, sometimes decades, while believing it is being protected.

(Like keeping milk in the oven. It is not illegal, but it will not end well.)

When Keeping Money in a Current Account Makes Sense—and When It Does Not

So far, we have dismantled the myth of the current account as a safe haven. But we are not here to spread financial panic. The current account has a precise role in financial planning; that role is simply much smaller than the one most Italians assign to it.

When money in a current account makes sense:

1. The emergency fund. Between three and six months of monthly expenses—not income, expenses—should remain liquid, available and boring. This is the parachute: it is there for genuine emergencies, such as job loss, unexpected medical expenses or urgent repairs. And it should be kept separate from the rest. If you want to understand how to size it, we discussed it in our emergency fund guide.
2. Planned expenses within 12 months. If you know that you have to pay a deposit on a house in eight months, that money stays in the account. Money needed in the short term should not be invested. Ever.
3. Operational liquidity. Your salary coming in and going out, bills and current expenses. The current account is a transactional tool, used to manage the cash flows of everyday life.

When money in a current account becomes a problem:

Everything else. If you have €100,000 in your account, your monthly expenses are €3,000 and you have no major purchases planned over the next 12 months, then €18,000–€20,000 cover your emergency fund and liquidity needs. The other €80,000 are losing value every day.

This does not mean that all €80,000 should go into stocks. The appropriate asset allocation depends on your objectives, time horizon, risk requirements and overall situation, including the tax wedge between income and wealth that weighs heavily in Italy.

It means that this money must work. In some way, through some instrument and at a level of risk calibrated to you. But it must work. Because every day it does not work, inflation works in its place. Except that it works against you.

A practical exercise:

Take your current-account balance. Subtract your emergency fund—three to six months of expenses. Subtract expenses planned for the next 12 months. What remains is the capital you are giving away to inflation. Multiply it by 0.02, representing 2% inflation. That is the annual cost of your “security”.

If the figure hurts, good. It means you understand.

The Most Expensive Choice Is the One That Does Not Look Like a Choice

There is a brutal asymmetry in personal finance, and no one talks about it enough.

When you invest and the market falls 15%, you see it. You feel it. Your banking app throws it in your face with red numbers and plunging charts. The news reports it. Your brother-in-law points it out over dinner. Every synapse in your brain screams: “You are losing money!”

When you do not invest and inflation eats 2% a year, you do not see it. You do not feel it. No app alerts you. No news programme reports it. No one tells you over dinner: “Did you know that this year you lost €2,000 in purchasing power without doing anything?” Your balance is identical. Everything appears fine.

But it is not fine.

Inflation losses are certain, constant and invisible. Market-volatility losses are uncertain, temporary and highly visible. And we—human beings with brains designed to flee from tigers, not to plan finances—react to visible threats and ignore invisible ones.

The result? €1.8 trillion sitting in Italian current accounts. At an annual inflation rate of 2%, this equates to approximately €36 billion in purchasing power destroyed every year. Thirty-six billion euros. Every year. In silence.

The “financial mattress”—whether it is a real mattress or a current account bearing the logo of a major bank—remains the most expensive investment a saver can make. Not because it charges fees. Not because someone is defrauding you. But because time and inflation together are an unstoppable machine. And the only way not to end up on the wrong side of that machine is to put it to work for you.

You do not have to become Warren Buffett. You do not have to obsess over the markets. You do not have to become a trader.

You simply have to stop paying the highest price: the price of doing nothing.

FAQ

But if inflation falls to zero, is keeping money in an account no longer a problem?

In theory, yes: with zero inflation, purchasing power does not erode. In practice, prolonged periods of zero or negative inflation—deflation—are extremely rare and typically associated with severe economic crises. The ECB’s objective is to keep inflation at around 2% per year, so planning on the basis of zero inflation is like planning on the assumption that it will never rain. Possible, but not prudent. Moreover, even in very low-inflation scenarios, the opportunity cost remains: money sitting in an account generates no return, whereas invested in a diversified portfolio it could have generated real growth.

Does a fixed-term deposit account not solve the problem?

It depends on the interest rate offered and inflation at the time. A deposit account yielding 3% gross—approximately 2.2% net—with inflation at 2% produces a real return of approximately 0.2%. Better than zero, certainly. But it is a partial solution, suitable for short horizons of one to three years and specific sums, typically an emergency fund or expenses planned for the near future. Over horizons of 10, 20 or 30 years, a deposit account does not solve the erosion problem and does not capture the growth potential that a diversified portfolio can offer. It is a bandage, not a cure.

How much should I keep in my current account?

The practical rule is: three to six months of monthly expenses as an emergency fund, plus expenses planned over the next 12 months, plus operational liquidity for current expenses. Everything else is capital losing value every day. The exact amount depends on your situation: someone with a stable income may stay closer to three months; someone with variable income or who is self-employed should tend towards six. But the most common mistake is not keeping too little—it is keeping too much. Many Italians keep sums in their current accounts equivalent to two or three years of expenses, paying an invisible but real price.

What if I am afraid of investing and losing money?

The fear is legitimate. Markets fall, sometimes sharply, and no one can guarantee that you will not lose money in the short term. But the question to ask is: what is the alternative? If the alternative is keeping your money idle, you are already losing money—the loss is simply invisible. This is not a choice between “risk” and “safety”. It is a choice between a visible, temporary risk—market volatility—and an invisible, permanent risk—inflation erosion. The solution is not to dive headfirst into the markets, but to build a plan consistent with your objectives and time horizon, with an asset allocation that allows you to sleep at night without giving your future away to inflation.
