Euro area households are sitting on nearly €10 trillion ($11.5 trillion) in cash and low-yield bank deposits, according to the European Central Bank (ECB). This cash pile represents approximately one-third of all the financial assets held by these households, earning little or nothing. New analysis from Revolut's European Wealth Drain Index reveals the true cost of this inaction - households forgo an average of €638 per €10,000 each year by staying in cash, with the opportunity cost calculated against the MSCI Europe ETF's ten-year annualised return of 9.06%. The study, conducted by financial technology company Revolut, is based on a survey of 20,007 adults across 20 EU member states along with official deposit and inflation data. Scaled across the €6.3 trillion in liquid deposits, this amounts to €422 billion annually in growth capital not reaching European businesses. The euro area covers the 20 countries that use the euro, and around 80% of households own no stocks or other market investments, as reported by the ECB. Recent ECB research reveals that around 80% of euro area households do not own stocks or any other market-based financial instruments, unlike their counterparts in the United States, where US households hold only 11% of their financial assets as deposits.
The real cost of inaction becomes clear when examining deposit performance against inflation. In 12 of the 20 markets included in Revolut's study, average one-year deposit rates fail to keep pace with inflation. Across the sample, deposits pay an average of 2.76% against inflation of 2.94%, meaning even savers who lock their money away are losing ground in real terms. The ECB's Consumer Expectations Survey shows that for households that are not financially constrained, perceived risk is the main barrier to investing in stocks or equity-based mutual funds. Limited knowledge and low trust in financial markets also deter many households from investing. Nearly half of respondents incorrectly assessed their returns after inflation, while 19% were unaware that inflation affected the value of their cash. One in five Europeans said they had no savings at all, according to Revolut's survey. The study found that two-thirds of respondents said they had never switched banks for a better rate, with 26% simply preferring their existing bank, 18% considering the difference negligible, and 15% not knowing where to look.
Recent ECB research has identified four distinct household archetypes based on how they allocate their wealth, each with different approaches to saving and investing. The 'real estate owner' household archetype can be found across the wealth distribution but is more common among middle and higher-wealth households, saving primarily for precautionary reasons and old-age provision. The 'deposit holder' archetype is concentrated in the lower wealth quintiles, whose main reason for saving is to ensure money set aside for unforeseen expenses or emergency savings. 'Pension product holders' cluster in the middle of the wealth distribution, with their main saving motive being old-age provision, consistent with their indirect exposure to capital markets through pension and insurance products. The 'capital market investors' – although a small minority – have a surprisingly diverse wealth profile and save mainly for old-age provision, reflecting the longer investment horizons often associated with direct market participation. Among households that can afford to invest, the ECB identified three main barriers to stock market participation: perceived risk of shares, thin knowledge of financial products, and low trust in financial markets. Revolut's survey reveals additional behavioral challenges, with over half using multiple financial apps, and among those, 45% say the fragmentation actively hinders investing.
The investment gap between European and American households widens as wealth increases. Among the richest fifth of households, more than 65% of Americans hold shares, bonds or funds, while the euro area figure is under 45%. This rules out affordability as the primary explanation, with the ECB stating that investment habits, the products on offer and the design of national pension systems all shape the outcome. The gap becomes more pronounced when considering that one in five Europeans has no savings at all, according to Revolut's survey. European Commission President Ursula von der Leyen has framed this as a competitiveness issue, stating that "Europe has savings. And unfortunately, those savings are sitting idle" and calling for the Savings and Investments Union to address the challenge. The Commission figure differs from Revolut's €6.3 trillion estimate because it covers household savings held in bank accounts across the entire EU, while Revolut's measure focuses on liquid deposits in 20 member states. The ECB's research confirms that the lower capital market participation of euro area households cannot be explained by affordability alone, with investment habits, product availability and differences in institutional structures (e.g. pension systems) also matter.
The Commission's €10 trillion figure covers household savings held in bank accounts across the whole EU, while Revolut's €6.3 trillion measure focuses on liquid deposits in 20 member states. The arithmetic behind Brussels' investment needs is straightforward - the Draghi report identified Europe's additional investment needs at €750 billion to €800 billion annually by 2030 to fund digitalisation, energy, defence and infrastructure. With public debt at 82.9% of EU GDP in the first quarter and 88.9% across the eurozone, according to Eurostat, the ECB outlined successful approaches including Slovenia's national financial education program and Finland's simple equity investment accounts. The European Commission has said that the Savings and Investments Union could unlock up to €470 billion in additional investment. The push comes as Europe faces significant investment needs, with Revolut's median first-time investment in the EU standing at €18, arguing that lowering the barrier to entry could encourage consumers to start investing. Recent ECB research emphasizes that better access to capital markets can help households earn higher returns and diversify their investments, requiring a combination of measures to address the specific limitations faced by different household groups.
