- The fact: Brazil's Central Bank published Resolution BCB No. 602, establishing new transparency and commercial governance requirements for banks and cryptocurrency exchanges.
- What changes: Consumers gain the right to select which categories of commercial products they do or do not want to receive via mobile app, email, and SMS.
- The timeline: Financial institutions and virtual asset platforms have until March 31, 2027, to adapt all internal systems.
Brazil's Central Bank (BC) has published Resolution BCB No. 602, dated October 23, 2026, establishing new guidelines for offering financial products and services in Brazil by banking institutions and virtual asset service providers—commonly known as cryptocurrency exchanges. The regulator's stated goal is to bring greater transparency to communications and put commercial proposals sent via digital channels under the direct control of the client.
The ruling directly impacts the marketing and relationship management routines of crypto asset platforms operating in the local market. With Bitcoin trading at US$ 80,484.18 (+0.60% on the day of the announcement), the regulation adds new layers of operational compliance without paralyzing the market, while redefining how investment products and crypto credit are presented to the end user.
What Changed Under the Central Bank's New Resolution for Crypto Exchanges?
The Central Bank established that cryptocurrency brokerages and banks must offer clear mechanisms for clients to choose exactly which types of commercial proposals they want to receive. The change eliminates the mass-marketing model where users were forced to receive loan alerts, leverage pitches, or new token promotions without segmented consent.
Under the new rule, digital channels—including app push notifications, emails, SMS, and messaging apps—must allow for granular preference management. In practice, if an investor uses a broker solely for Bitcoin custody, they can explicitly disable notifications about higher-risk products, such as crypto-collateralized loans or derivatives trading.
Beyond advertising management, Resolution BCB No. 602 includes additional restrictions on granting credit to clients experiencing financial vulnerability or a high risk of over-indebtedness. This safeguard prevents financial institutions and brokerages from actively targeting vulnerable income profiles with financing offers or automatic credit lines.
What Are the Direct Obligations for Crypto Brokerages?
The Central Bank's new rules add operational and technological obligations that directly affect the country's cryptocurrency ecosystem. Platforms will need to restructure their privacy centers and terms of use ahead of the March 2027 deadline.
Clients must be able to individually select whether they want to receive credit proposals, crypto fixed-income products, or new assets.
Sending active credit proposals to users identified as experiencing financial vulnerability is prohibited.
Brokerages and institutions have until 03/31/2027 to reconfigure preference panels in their applications.
The Central Bank's initiative aims to align virtual asset service providers with the same transparency obligations applied to major retail banks. For international exchanges operating in the country, this means adapting global app codebases to meet the specific requirements of the Brazilian market.
How Are Credit and Leveraged Crypto Products Affected?
The offering of crypto-backed credit had been growing rapidly in Brazil, allowing investors to use their Bitcoin or stablecoin balances as collateral to take out loans denominated in reais. The Central Bank targeted precisely how these operations are promoted to users.
With Resolution BCB No. 602, the BC blocks aggressive outreach during periods of volatility. Platforms will no longer be allowed to send automated blasts encouraging users to take out credit during market downturns simply to top up margin collateral across their entire user base.
Watch the risk profile: The new rule does not ban borrowing against crypto collateral, but it prevents brokerages from making active, targeted credit offers to financially vulnerable clients. Sending advertising will now require prior, categorized consent.
This change reduces commercial solicitation and protects retail investors who, during periods of euphoria or stress in the crypto market, faced constant pressure to increase their leverage on the platform.
What Is the Implementation Schedule Set by the Central Bank?
The publication of the text in late October 2026 establishes a transition window for the entire financial and crypto sector to make the necessary technical adjustments. The regulator acknowledged the complexity of modifying notification data architectures and granted a reasonable timeframe for the rules to take effect.
During this adaptation period, retail investors will not notice immediate changes in their apps. However, crypto exchanges have already begun reviewing their software development backlogs to include regulatory preference configuration screens.
What Changes in Practice for Retail Investors?
For users who trade Bitcoin, Ethereum, or stablecoins on a daily basis, the resolution delivers a cleaner operating environment focused on individual privacy and communication control.
You will no longer be bombarded with unwanted notifications for products you do not use. If your goal is simply to hold Bitcoin in custodial storage, you can turn off all alerts regarding loan offers, platform credit cards, or futures trading, keeping only what actually interests you active.
Additionally, the regulation reinforces the institutional security of the crypto asset market in Brazil. By equating exchange obligations with traditional financial system guidelines, the Central Bank is consolidating a more mature business environment safeguarded against abusive digital marketing practices.
What Should You Monitor Until the New Rules Take Effect?
Through March 31, 2027, the crypto market will undergo a quiet period of technical adjustment behind the scenes. Investors should keep an eye on app updates from their brokerages over the coming months.
Terms of Use Updates — Follow communications sent by exchanges regarding new data privacy and consent terms.
Preference Panel — Watch for the release of the notification management tab in your broker's app to configure which offers you wish to receive.
Supplementary Regulation — Monitor whether the Central Bank issues additional ordinances detailing specific operational rules for asset segregation and final licenses for virtual asset providers.
Rico aos Poucos Verdict
Central Bank Resolution BCB No. 602 represents another consistent step toward the professionalization of the cryptocurrency market in Brazil. By giving consumers the power to disable invasive notifications and curb irresponsible credit offerings, the regulator raises the compliance bar for exchanges. The move directly benefits conscious investors, who gain a more transparent digital environment less prone to aggressive commercial solicitation.
