Criminals laundered $8.6B in cryptocurrency in 2021, up from $6.6B in 2020 but below $10.9B in 2019; exchanges received 47% of the funds and DeFi received 17%

Context & Ripple Effects
This Chainalysis preview lands two weeks after the firm reported a record $14B flowing into criminal crypto addresses in 2021, driven by DeFi rug pulls that cost owners $7.7B. The laundering figures are the other half of that pipeline: money has to exit, and the report maps where it goes.
The destination split is the news: exchanges still took 47% of laundered funds, but DeFi's 17% share marks its arrival as a laundering venue — a shift Chainalysis would confirm a year later when illicit addresses sent nearly $23.8B in 2022 with DeFi receiving record funds.
First-order effects
- Centralized exchanges remain the dominant off-ramp at 47% of laundered funds, keeping them squarely exposed to KYC/AML obligations and sanctions exposure on every tainted deposit.
- DeFi protocols absorbed 17% of laundered funds despite holding no identity checks, meaning the year's scam-driven inflows — largely rug-pull proceeds — found an exit route outside traditional exchange controls.
Second-order effects
- Exchanges gain leverage over regulators by pointing to their 47% share as evidence they are the enforceable chokepoint, while arguing that DeFi's growing slice is a gap only rulemaking can close.
- Blockchain-analytics vendors like Chainalysis see rising demand for DeFi-capable tracing tools, since the prior enforcement playbook built around concentrated deposit addresses — where just five services once drove 55% of 2020 laundering ($1.3B) — does not map onto smart-contract venues.
Third-order effects
- If laundering keeps migrating from exchanges to DeFi, the structural assumption behind crypto AML — that fiat off-ramps are the interception point — erodes, pushing regulators toward protocol-level requirements rather than entity-level ones.
- The trajectory Chainalysis documents here through 2022 suggests crime measurement itself becomes the industry's de facto compliance infrastructure, with annual reports shaping which venues get scrutinized next.
The trend: Crypto money laundering is shifting from centralized exchanges toward DeFi, moving the regulatory battleground from exchange KYC to protocol-level oversight.
