Best quote from CDB: O Guia para ser o Credor do Banco e Lucrar com a Selic
Ao investir em um CDB, você inverteu a lógica do sistema bancário e virou o banco do banco. É basicamente um contrato de empréstimo onde a instituição financeira é quem está te devendo.

Frequently Asked Questions
Como Lena e Miles explicam, investir em um Certificado de Depósito Bancário (CDB) inverte a lógica tradicional do sistema financeiro. Em vez de pagar juros ao banco, você assina um contrato de empréstimo onde o banco passa a te dever. O banco utiliza o seu capital para financiar operações diversas, como empréstimos de veículos ou financiamento de empresas, e em troca paga a você uma remuneração pelo uso desse dinheiro.
Com a taxa Selic atingindo o patamar de 14,75% ao ano em junho de 2026, o papel de credor do banco torna-se extremamente lucrativo. Miles destaca que esse cenário de juros altos favorece diretamente a renda fixa, permitindo que o investidor receba uma parcela significativa do lucro das operações bancárias. É uma oportunidade estratégica para quem busca rentabilidade sólida através de títulos de dívida bancária.
A rentabilidade varia conforme a instituição financeira e a necessidade de captação de recursos. Lena aponta que, enquanto grandes bancos podem oferecer apenas 85% do CDI, instituições menores chegam a oferecer até 140% do CDI para o mesmo tipo de produto. Essa discrepância brutal de taxas mostra a importância de pesquisar e comparar as opções para maximizar os ganhos no mercado de renda fixa.
