Crypto Market Abuse: Wash Trading, Spoofing and What MiCA Title VI Requires

Most reported crypto trading volume is not real. An NBER study found more than 70% of reported volume on unregulated exchanges is wash trading. MiCA Title VI exists to fix that: it extends the EU market-abuse regime to crypto-assets, and a trading platform must prevent, detect and report abuse. This article explains what counts as market abuse and what surveillance you have to build.

For the build, see our MiCA compliance software development and the market-abuse surveillance section on the MiCA page.

What MiCA Title VI prohibits

MiCA Title VI mirrors the EU Market Abuse Regulation for crypto-assets admitted to trading. It prohibits insider dealing, the unlawful disclosure of inside information, and market manipulation. Crypto-asset service providers operating a trading platform must have systems and procedures to detect and report it.

The manipulation patterns you must catch

• Wash trading and self-trading. Matched buy and sell activity that fakes volume or price.
• Spoofing and layering. Non-bona-fide orders placed to move the book then cancelled before execution.
• Momentum ignition and ramping. Aggressive sequences designed to trigger other participants or stops.
• Pump and dump. Coordinated inflation of a thin token followed by a coordinated exit.
• Insider dealing. Trading ahead of listings, delistings or token-event announcements.

What a trading platform must do

• Run order-book and trade surveillance against statistical baselines
• Correlate on-chain and cross-venue data to catch abuse a single book cannot show
• Generate suspicious transaction and order reports (STOR) for the national competent authority
• Keep an immutable audit trail behind every alert and report

How crypto surveillance actually works

Effective surveillance is more than threshold alerts. It baselines normal behaviour per market, scores deviations, and routes alerts to an analyst queue with case management. On-chain data adds context a traditional venue never had: wallet clustering, funding sources and cross-venue flows. The hard part is tuning thresholds to each market’s liquidity so analysts are not buried in false positives.

Building crypto market surveillance

We build order-book surveillance, on-chain and cross-venue correlation, alert triage and STOR generation, wired into your existing matching engine and writing to the same audit trail as the rest of your MiCA controls. We do not promise zero false positives. We build an explainable, auditable pipeline a regulator can follow end to end.
