Root Cause

Brazil's CVM Resolution 175 (effective 2023) requires foreign investors to register with a CNH (Custódia Nacional de Habilitação) account at a B3 broker, which involves a specific compliance process including a local tax representative and a valid CPF linked to the CNH, and AI omits this because it treats Brazilian stock trading as equivalent to US markets where a simple brokerage account suffices.

巴西CVM第175号决议（2023年生效）要求外国投资者在B3经纪商处开设CNH（国家托管资格）账户，这涉及特定的合规流程，包括本地税务代表和与CNH关联的有效CPF，AI忽略这一点是因为它将巴西股票交易等同于美国市场，在美国只需一个简单的经纪账户即可。

Workarounds

  1. 85% success Advise the foreign investor to engage a Brazilian broker (e.g., XP Investimentos, Modalmais) that offers foreign investor onboarding. Steps: 1) Obtain a CPF via the Brazilian consulate. 2) Open a local bank account (e.g., Banco do Brasil). 3) The broker opens a CNH account. Example: 'Submit CPF, passport, and proof of address to XP's foreign desk; they will file the CNH registration with B3 within 5 business days.'

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Interactive Brokers requires a CNH account for B3 trading; without it, the broker can only offer OTC derivatives or US-listed Brazilian ADRs, not direct B3 stocks. The CPF alone is insufficient for settlement.

  2. 75% fail

    CPF is a tax ID, but for B3 trading, the CNH account acts as the custody account linked to the CPF; the broker must open the CNH via a B3-participating custodian (e.g., Itaú, Bradesco), which requires a local bank account and tax representative.

  3. 85% fail

    CVM Resolution 175 prohibits nominee or beneficial ownership structures without proper disclosure; the investor must be the registered owner of the CNH, or face fines and account freezing by B3.
