What is a store of value?
Correct answer
Answer B: Something that can preserve purchasing power for you to use later.
Quick explanation
This function is called a store of value. If the same amount of money buys much less over time, that money performs this function less well.
Detailed explanation
Someone who sells their work does not have to spend the proceeds immediately. As a store of value, money can carry the ability to buy goods or services into the future. What matters is therefore not just the amount printed or displayed, but its future purchasing power.
No store of value is completely risk-free or equally good in every situation. Cash can lose purchasing power through inflation. Assets can fluctuate in market price, incur costs or be difficult to sell. Security, durability, storage and legal risks also matter. The store-of-value function therefore does not guarantee that an amount will always retain the same real value.
An objective assessment must distinguish the nominal amount from real purchasing power. A form of money can work extremely well as a medium of exchange even if it performs less well as a store of value over long periods.
Example or everyday application
You set aside 1,000 euros for a future repair. After two years, the account still holds 1,000 euros. If repairs have become much more expensive in the meantime, the nominal amount has stayed the same, but its purchasing power has fallen.
Common misconception
Serving as a store of value does not guarantee an unchanging price. What matters is how much economic purchasing power is retained over the period considered.
