High inflation significantly erodes the purchasing power of money.

This is perhaps the most immediate and tangible effect for individuals. When inflation is high, the cost of goods and services rises rapidly. A hundred dollars today might buy a week's worth of groceries, but in a year, that same hundred dollars may only cover a few days' supply. Your money, effectively, loses its buying strength. This erosion impacts savings held in cash or in accounts with low interest rates, as their real value diminishes over time. It makes planning for future expenses like retirement or education incredibly challenging, as the projected costs become moving targets.
