Between inflation, uncertainty and changes in financial behavior, liquidity is becoming a macro variable that impacts investment, credit and growth. In the public debate the question recurs with a note of irritation: why do families continue to keep so much liquidity still, right now that rates have gone back to “doing their job”? The short answer is that there is no single reason.
The useful answer could be that liquidity today has become a thermometer: it measures together trust, fear, system misalignments and the quality of the financial offer.
The starting data is already news in itself. The ECB recalled that European families hold over 12,000 billion euros in cash and deposits, around a third of their financial assets. Within this mass, a very significant part remains in forms with very low remuneration, in particular on “overnight” deposits, i.e. de facto current accounts. And here comes the first friction: while official rates rose and then started to fall, the remuneration of sight accounts remained modest. In the euro area, in December 2025 the rate on household overnight deposits was 0.25%, against higher levels on some restricted forms.
A part of the savings is not stopped because “there are no alternatives”. It is firm because, in the minds of those who decide, the alternative is not yet convincing enough.
Liquidity as psychological insurance after years of shock
There’s an often overlooked dynamic: money in accounts isn’t just a financial choice, it’s an emotional choice. Those who have gone through a pandemic, war, inflation peaks and energy instability in just a few years have learned a simple principle: normality can fail.
It is not surprising that a line of analysis by the ECB has even put the role of cash as a “spare tyre” back at the center in times when digital systems do not work or trust falters. This narrative, which once would have seemed marginal, becomes mainstream: liquidity is perceived as protection against the unexpected, even before being a portfolio choice.
It is also why inflation has a paradoxical effect. In theory it should push you to invest; in practice, when it is high and “aggressive”, it can produce the opposite reaction: stiffening. You save in liquid form to have control, to postpone decisions, to avoid making mistakes in timing. It’s behavioral finance applied to real life.
The real issue: the liquidity premium against an offer perceived as complicated
The European problem is not just cultural: it is also industrial. If such a large share of wealth remains in deposits, it means that the market is not effectively converting savings into investment.
The ECB says it bluntly: if the share of European household deposits approached that of the United States, up to 8,000 billion could be redirected towards long-term investments, with a potential annual flow of more than 350 billion. It is a sentence that is valid as a diagnosis: Europe is rich, but often immobilized.
And here comes a theme that matters more than any moralism: many savers are not “choosing liquidity” in the abstract, they are choosing not to choose an offer that they perceive as opaque, expensive or too risky. Meanwhile, the European Union has strengthened rules and incentives to push retail investment into the capital markets, precisely because a huge part of savings remains in the bank instead of financing growth and businesses.
Liquidity is also a vote of no confidence in the financial distribution chain, not just a prudential instinct.
The interest rate paradox: higher yields, but still imperfect pass-through
Then there is a technical fact that becomes political: the increase in rates was not transmitted symmetrically to mortgages and deposits. Many families have seen the cost of money rise, but have not perceived an equally clear benefit on their parked liquidity.
ECB statistics clearly show that the remuneration of sight deposits remains low, while deposits with an agreed maturity yield more. Yet the mass does not move as much as it “should”. Why?
Because liquidity pays a premium that is not in the rate: it pays in flexibility. In an uncertain age, the ability to divest without friction has real value, especially when the difference between “leave in the account” and “lock in” does not appear large enough to justify the loss of control. It’s not just prudence: it’s also demographics, real estate wealth and imminent needs.
There is a piece of history that is often overlooked: liquidity is also a parking lot “waiting for”. Down payment for a house, help for children, renovations, health expenses, support for elderly parents. In an aging society, the need for ready-made bearings increases.
And then there is another variable: real estate wealth. In countries like Italy, where the house weighs heavily on assets, liquidity often takes on a balancing role: it is the liquid counterweight to an illiquid asset. It’s not always inefficiency: sometimes it’s the domestic architecture of risk.
What this means for the economy: slower growth and more expensive capital
When too much money sits still, the system pays a price. The first effect is macro: less savings transformed into productive investments means less patient capital for businesses, innovation and energy transition. It is one of the reasons why Europe insists on the need to move wealth towards capital markets, without dumping everything on the banks.
The second effect concerns credit and banking stability: deposits are a source of funding, but their composition matters. If they remain mainly overnight, they are more “volatile” in the event of a confidence shock. It is no coincidence that the ECB has flagged potential risks also linked to new dynamics such as the growth of stablecoins, which could drain deposits from the traditional banking system.
The third effect is more subtle: mass liquidity can coexist with the perception of economic insecurity. It is a typical signal of the phases in which families and businesses prefer reversible options instead of irreversible choices. And this, historically, is not the ideal habitat for robust growth.
Is liquidity “too much” or is the market not offering enough confidence?
The point is not to blame those who keep money in the account. The point is to understand why, after years of shocks, liquidity is winning against alternatives that in theory offer returns.
If the answer was just “financial ignorance”, education would be enough. But the signals tell something more complex: liquidity has become a language. He says trust is selective. That the perceived risk is not only in the markets, but also in the complexity of the products and the stability of the context. That many savers prefer a certain return (even if low) to a higher but emotionally costly promise.
And here lies the real implication: as long as that mass remains still, Europe will continue to move with a tight brake. Liquidity is not just a “non-investment”. It is a system indicator. And like all serious indicators, it should not be judged: it must be interpreted. Then, if anything, corrected with policies, transparency, competition and tools that truly deserve trust.
