In One Sentence

Wash trading is deceptive trading arranged to create apparent activity without a genuine change in economic exposure.

Wash trading is deceptive trading arranged to create apparent activity without a genuine change in economic exposure. It can involve one party trading through accounts under common control, or coordinated transactions designed to neutralize meaningful market risk.

Why reported volume can mislead

Such trades can make an asset or venue appear more actively traded than it really is. Observers may mistake the recorded turnover for independent demand or readily available liquidity. In crypto markets, this concern applies to fungible tokens as well as NFT transactions.

For example, transfers between wallets controlled by the same person may generate a sequence of apparent sales. The transaction history alone does not establish that independent buyers paid the displayed prices. Equally, shared ownership cannot always be inferred from a public address alone.

Distinguishing manipulation from normal trading

Buying and later selling an asset is not automatically wash trading. Market making, hedging and accidental self-matches require assessment of intent, control and actual exposure.

Wash-trading prohibitions and enforcement depend on the instrument, venue and jurisdiction; CME expressly prohibits wash trades under its rules. Volume figures therefore need context, including market depth and the quality of counterparties, rather than being treated as proof of trustworthy demand.
