This common money move may 'feel safe,' but it can be a silent wealth killer—what to do instead, from an investing expert

TL;DR

Keeping too much savings in cash can lead to a loss of wealth-building potential due to inflation.
Inflation erodes the spending power of cash over time; for example, $126 in 2026 may have the purchasing power of $100 in 2020.
Traditional savings accounts earn low interest rates (around 0.39%) that are often lower than the inflation rate (around 2.4%).
While high-yield savings accounts offer better rates (up to 4%), most people earn significantly less.
Investing cash in the market, like the S&P 500, can help outpace inflation and retain purchasing power, with the S&P 500 delivering average annual returns of around 13%.
Cash is suitable for short-term needs and emergency reserves, but not for long-term growth.
Investing $1,000 with a 10% annual return for 10 years, even accounting for inflation, results in significantly more real value than the same amount in a savings account.
Investing early allows money to benefit from compounding.
Index funds pegged to the S&P 500 are recommended for broad market exposure, reliable returns, and lower fees.
Experts recommend keeping 3-6 months of expenses in an emergency savings fund, potentially divided into 'spending shock' and 'income shock' buckets.
Automatic contributions and high-yield savings accounts can help build savings and at least keep pace with inflation.
