These questions were asked to people around the world, and the correct answers are A, C, and B. Did you get them all right? If you did — congratulations, you understand the basics of how interest rates, inflation, and portfolio diversification work. Most people surveyed around the world didn’t.
In Russia, 96 percent of those surveyed failed to answer the three questions correctly. In the U.S., 70 percent failed. The highest performing countries were Germany where 47 percent failed and Switzerland, where 50 percent did. But this isn’t rocket science. The questions reflected basic financial concepts that are essential for saving for the future, using credit cards, taking on a student loan, purchasing a home, investing, and building up a pension.
Worse than this, Americans also showed overconfidence in their abilities. Asked to rank their financial knowledge on a scale of 1 (very low) to 7 (very high), 70 percent of Americans surveyed ranked themselves at level 4 or higher. Yet only 30 percent answered the questions correctly.
These surveys provide some pretty scary food for thought, because uninformed, overconfident people are more prone to make bad decisions that endanger their own financial health and the wider economy. As this paper from the World Bank shows, individuals who are financially literate have better financial situations.
