Willful blindness and money laundering.

Willful blindness allows conduct to be treated as intentional when a person, faced with clear signs of illegality, chooses not to confirm what is happening in order to later claim ignorance. The idea comes from Anglo-American law; in Brazil, it runs into strict limits.

The “should have known” standard is not enough. Two elements must be shown at once: awareness of the high probability of the unlawful fact and a deliberate decision not to confirm it. These two requirements match the test set by the United States Supreme Court in Global-Tech v. SEB (2011). If either is missing, there is, at most, negligence, which does not support a money-laundering conviction. And because Brazilian criminal law requires intent and forbids strict liability, the doctrine cannot replace proof of knowledge.

Law No. 9,613/1998 imposes on certain sectors the duty to identify clients and report suspicious transactions to Coaf, the Brazilian financial intelligence unit. Obligated persons include jewelers, dealers in precious stones and metals, car dealerships and high-value goods retail (art. 9). These are the sectors that have featured in recent investigations for reporting failures: transactions inconsistent with the client profile, internal alerts left unreported, high-value sales without record.

For these businesses the question is concrete: at what point does failing to act on a red flag stop being a process failure and acquire criminal relevance. The answer depends on the subjective element and on how well the company documented the precautions it took.

Brazilian law itself has begun to separate conduct once treated together. Law No. 15,397/2026created a stand-alone offence for lending a “straw” bank account (art. 171, §2, VII, of the Criminal Code), carrying a lesser penalty than money laundering, recognizing that the intermediary is not always the launderer and that the subjective element must be assessed case by case.

Does a money-laundering conviction require proof of knowledge of the unlawful origin?

Yes, in the sense that the “should have known” standard is not enough. It must be shown that the person was aware of the high probability of illegality and deliberately decided not to confirm it. Without those elements there is, at most, negligence, which does not support a conviction.

Which sectors are obligated to report transactions to Coaf?

Among others, jewelers, dealers in precious stones and metals, car dealerships and high-value goods retail, under art. 9 of Law No. 9,613/1998. Non-compliance may lead to administrative and, depending on the case, criminal consequences.

Can ignoring a compliance alert have criminal consequences?

It may be weighed as evidence, depending on the context. How the alert was handled, and whether it was recorded, is relevant to assessing the subjective element.

What distinguishes willful blindness from negligence?

Negligence is the breach of a duty of care without awareness of the unlawful fact. Willful blindness presupposes awareness of the high probability of illegality and a deliberate choice not to confirm it, approaching intent.

Do compliance programs affect liability?

A proportionate, effective and documented program helps to show the absence of a deliberate refusal to learn the facts, and is a relevant element of defense.
