volume inflation

A rise in reported trading volume that reflects incentive-driven churn rather than genuine liquidity or disagreement — for example where an exchange rewards market makers for posting at minimum size, so quotes that are immediately picked off generate large notional turnover without leaving any lasting depth in the book. Distinguishable from wash trading in that no collusion between counterparties is needed, but it likewise makes headline volume misleading as a measure of market activity.
