More than six in ten eurozone households would refuse to buy shares even after winning 50,000 euros, a European Central Bank survey found.
For most participants in an experiment covering approximately 9,700 households across the euro area, the answer regarding direct stock purchases was nothing. Over 60 percent of families stated that they would not buy company shares even if they won the maximum cash sum.
Larger payouts did prompt a relative shift toward the stock market among some participants. Yet for those who were willing to invest, the proportion of money placed into shares or mutual funds changed very little across different prize levels.
The findings emerged from a research project that examined willingness to invest across varying levels of sudden personal wealth. Economists Dimitris Christelis, Dimitris Georgarakos, Tullio Jappelli and Geoff Kenny conducted the study using data from the European Central Bank.
The five lottery amounts
The four researchers drew on the central bank's Consumer Expectations Survey to measure how ordinary savers react to sudden financial gains. Dimitris Christelis, Dimitris Georgarakos, Tullio Jappelli and Geoff Kenny sought to determine whether larger sums could overcome retail investors' traditional hesitation toward the stock market. In June 2021, they randomly assigned each respondent one of five hypothetical lottery prizes ranging from 5,000 euros to 50,000 euros.
The survey asked participants to explain exactly how they would allocate the windfall over the next twelve months. All answers evaluated hypothetical winnings rather than actual cash payouts, allowing economists to compare how different sums altered household decisions without placing real money at stake.
The representative sample drew on households across six major euro area economies: Germany, France, Italy, Spain, the Netherlands and Belgium. The responses gave researchers a consistent picture of consumer attitudes across northern and southern Europe, showing similar resistance to equities across diverse national banking systems.
Behavioral finance and cash windfalls
The project highlights core ideas in behavioral finance, an economic field that explores how psychological factors shape monetary choices. The discipline demonstrates that people tend to invest money that arrives unexpectedly far more aggressively than earnings built through regular employment.
Economists study this pattern through concepts such as mental accounting and the windfall effect. Savers often separate surprise cash gains from their accumulated savings, treating windfalls as disposable resources that carry lower emotional risk than wages earned on the job. In classical economic theory, every euro holds the exact same value regardless of how a person acquired it, but psychological research demonstrates that people handle money differently based on its origin.
Yet the survey showed that this increased appetite for risk had clear limits among European consumers. Even when presented with a theoretical windfall of 50,000 euros, the vast majority of households preferred to avoid direct stock market investments entirely.
European stock market participation
The European Central Bank, based in Frankfurt, Germany, established the monthly Consumer Expectations Survey to track consumer perceptions of inflation, economic growth and household finances. The survey covers thousands of consumers across member nations, giving central bank policymakers regular insight into how families manage debt, spending and savings.
Direct equity ownership among European retail savers has historically remained lower than rates recorded in the United States and the United Kingdom. Households in economies such as Germany, France and Italy have long favored secure bank deposits, guaranteed savings schemes and residential real estate over company shares, reflecting a cautious approach to personal wealth.
The study demonstrated that while larger windfalls can encourage some savers to consider equities, deep reluctance to purchase company shares remains the standard position for most families across the eurozone.
