A nominal balance may remain unchanged while its purchasing power rises or falls.
For long-term comparisons, the quantity of currency is often less informative than the amount of real goods and services that currency can command.

Purchasing power translates a monetary balance into real economic terms. If the same unit of currency buys fewer goods and services than before, its purchasing power has declined.
