Barter System
A barter system exchanges goods or services directly without a generally accepted monetary intermediary, creating valuation, matching, and recordkeeping challenges.
How money functions as a payment medium, unit of account, store of value, deferred-payment standard, and source of issuance income.
Money functions and forms explain what an instrument does in an economy and what kind of claim or asset it is. A bank deposit, banknote, gold coin, payment card, and privately issued token can all participate in payments, but they do not create the same legal claim, settlement risk, redemption right, monetary function, or seigniorage effect.
Start with Money for the complete framework. Use the narrower pages when the distinction changes a payment, liquidity, inflation, accounting, or risk conclusion.
| Function | Question it answers | Key limitation |
|---|---|---|
| Medium of Exchange | Can users transfer it to settle purchases? | Acceptance and settlement can be limited |
| Unit of account | Are prices and obligations denominated in it? | A pricing unit need not be the asset delivered |
| Store of Value | Can purchasing power be carried into the future? | Inflation, market, credit, and custody risks remain |
| Standard of deferred payment | Can current and future obligations be stated consistently? | Contract value can diverge from real purchasing power |
| Form | Source of monetary acceptance | What to verify |
|---|---|---|
| Fiat Money | Official unit, institutions, payment systems, taxation, and public use | Issuer, claim, legal status, and purchasing-power risk |
| Commodity Money | Monetary use plus value of the material itself | Weight, purity, assay, market value, and legal rules |
| Representative money | Redeemable claim on an underlying asset | Issuer, reserve assets, redemption terms, and custody |
| Commercial-bank money | Transferable deposit claim on a bank | Account access, settlement, credit risk, and protection rules |
| Barter | Direct agreement to exchange goods or services | Valuation, timing, quality, recordkeeping, and tax treatment |
Seigniorage explains economic value or income associated with issuing money. Coin production margins, real resources from money creation, central-bank asset income, accounting profit, and government remittances are related but distinct measures.
Identify the unit of account, issuer, holder’s legal claim, settlement asset, redemption promise, and relevant jurisdiction. Then separate nominal value from real purchasing power and distinguish the money itself from the payment instruction or technology used to transfer it.
These pages are educational. They do not determine whether a currency, commodity, deposit, or digital asset is suitable for a particular user.
Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.

Commodity money is a commodity used as money whose material has market value apart from its monetary role.
Fiat money is money denominated in an official unit that is not redeemable for a fixed quantity of a commodity and is sustained by law, institutions, policy, and public acceptance.
A medium of exchange is an instrument or claim accepted in payment, allowing buyers and sellers to transact without direct barter.
Money is an asset or claim widely used as a medium of exchange, unit of account, store of value, and standard for deferred payment.
Seigniorage is economic value or income associated with issuing money, measured differently for coinage, money creation, and central-bank income.
A store of value is an asset expected to carry purchasing power into the future, subject to inflation, market, credit, liquidity, and custody risks.
