By Brazil Stock Guide – Brazil’s securities regulator moved to redraw the boundaries between independent investment advice and product distribution, intensifying pressure on the way large digital platforms sell bank notes and structured products to retail clients.
An interpretive circular issued on Jan. 19, 2026 by the Comissão de Valores Mobiliários (CVM) clarifies that registered investment advisors must act exclusively in the best interests of investors, even when operating alongside distributors whose business model depends on volume, commissions and product placement.
The guidance comes as platforms such as XP (NASDAQ: XP) and Nubank (NYSE: NU) dominate retail access to capital markets, combining distribution scale, digital interfaces and marketing power. Within these ecosystems, products like CDBs issued by mid-sized lenders — including Banco Master — and COEs linked to listed companies such as Braskem (B3: BRKM5) and Ambipar (B3: AMBP3) have become staples of the retail offering, often presented as yield-enhancing or capital-protected alternatives in a volatile rate environment.
Fiduciary duty under stress
At the core of the CVM’s message is a firm distinction between the buy side and the sell side. Under CVM Resolution 19, investment advisors are fiduciaries. They must assess client profiles, risks, costs and suitability, and place client objectives ahead of their own interests or those of product issuers. Distributors and their agents, by contrast, operate on the sell side, remunerated for placing product and expanding distribution.
The circular acknowledges a market reality: advisors may, in some structures, receive indirect remuneration from issuers or distributors. This is common in COEs and in promotional CDB campaigns, where margins are embedded in the product economics. The regulator, however, draws a hard line. Any such remuneration must be fully rebated to the investor, through a clear reduction in advisory fees, explicitly authorized in contract and supported by detailed disclosure and calculation reports.
Distribution at scale
This framework has direct implications for platforms built on scale and cross-selling. The rapid expansion of Brazil’s retail investor base over the past decade has relied on simplified narratives, digital onboarding and curated product shelves. In practice, recommendation, marketing and execution have often converged in the same interface, blurring the distinction between advice and sales.
CDBs from smaller or mid-sized banks gained traction as interest rates rose, offering higher yields than large-bank deposits. COEs, meanwhile, appealed to investors seeking exposure to equities or credit narratives with defined payoffs and downside protection. Tied to recognizable corporate names, these products benefited from brand familiarity, even when their risk-return profiles were complex or opaque.
Who benefits, who loses
Independent, fee-based advisory firms stand to gain from the clarification. The CVM’s stance strengthens their value proposition by reinforcing independence as a regulatory requirement rather than a marketing claim. Transparent pricing and clean alignment of incentives become competitive advantages.
Platforms and distributors that rely on embedded commissions and aggressive placement strategies face higher compliance costs and narrower room for maneuver. While the circular does not prohibit the sale of CDBs or COEs, it raises the regulatory and reputational risks of treating advisory functions as extensions of product sales.
What comes next
The timing is critical. Brazil’s capital markets have matured, but retail participation remains sensitive to trust and perception. Regulatory tightening tends to follow periods of rapid growth, especially where complexity meets scale. By formalizing expectations around conflicts, disclosure and fiduciary duty, the CVM signals closer supervision of how advice is delivered and monetized.
The message to the market is direct and structural. Advice is not distribution. Independence is not optional. In an ecosystem built on volume and velocity, the regulator is asserting that alignment must be proven — in contracts, in cash flows and in conduct.
