Many Israelis are unknowingly losing significant value on their savings by leaving large sums in bank current accounts, as inflation steadily erodes purchasing power. Over the past thirty years, money left idle in accounts has lost more than half its value, while even modest investments in shares would have yielded substantial real returns. Experts argue that the real risk is not short-term market volatility, but the certainty of cash erosion over time, especially as inflation has surged in recent years. While maintaining some cash for daily needs is sensible, financial professionals recommend diversifying into assets like stocks, bonds, and real estate to preserve and grow wealth, rather than letting it 'evaporate' in the bank.
