The Superior Court of Justice (STJ) has just signaled a relevant point for the capital market: liability for losses in investment funds cannot be automatically extended to all members of the financial chain.
In the judgment of REsp 2,230,861, the 3rd Panel dismissed the joint liability of participants who did not have a direct role in the mismanagement of the fund, maintaining the conviction only of the administrator responsible for managing the portfolio.
The controversy involved a fund aimed at conservative investors, promising immediate liquidity (D+0), which suffered a significant devaluation after problems involving the asset manager Infinity Asset, which was subsequently sanctioned by the CVM (Brazilian Securities and Exchange Commission).
The decision is relevant because it reinforces a logic that is increasingly present in financial market law: the functional segmentation of responsibilities.
Minister Daniela Teixeira highlighted that:
• The funds are responsible for their own legal and contractual obligations;
• Service providers are liable for damages resulting from their specific activities;
• There is no automatic or objective liability for all agents simply because they are part of the investment structure.
In this specific case, the Superior Court of Justice (STJ) understood that:
The mismanagement was attributed exclusively to the administrator;
→ there was no demonstration of fault on the part of the distributor;
→ successor funds could not be held liable for the fraud attributed to the previous administrators.
Minister Ricardo Villas Bôas Cueva also drew attention to the reform promoted by the Economic Freedom Law (Law 13.874/19), which has more clearly structured the allocation of risks in the capital market, reinforcing the idea that each participant is only responsible for acts within their sphere of activity.
In practice, the judgment:
✔ Reduces the risk of expansive liability in the financial market;
✔ Strengthens regulatory predictability;
✔ It brings civil liability closer to the functional logic foreseen in the CVM regulations;
✔ and is likely to impact future discussions on joint liability among administrators, managers, distributors, and other fiduciary agents.
The precedent also engages with a broader debate: to what extent can investor protection justify the indiscriminate expansion of civil liability in complex financial structures?
