Investors Face Hidden Risks in CDBs from Small Banks: FGC Guarantees up to R$ 250,000, but Delays Reduce Promised Returns from 20% to Only 8% Per Year
The “Miraculous” CDBs offered by small and medium banks attract investors with yields well above the market average. Rates of 18% to 20% per year seem irresistible compared to securities from large institutions. However, as financial educator Bruna from the channel Ela Investe explained, the issue isn’t just the risk of bank failure — but the time during which the money remains unearned until the reimbursement from the Credit Guarantee Fund (FGC).
How the FGC Protection Works for “Miraculous” CDBs
The FGC guarantees up to R$ 250,000 per CPF and per institution, with a global limit of R$ 1 million every four years. This means that, in the event of a bank’s bankruptcy, the investor recovers the invested capital, but only up to these amounts. Coverage extends to CDBs, LCIs, LCAs, savings accounts, and even checking account deposits.
Many believe that this protection eliminates risk, but in practice, that’s not the case. The FGC only reimburses the invested amount, not the projected interest until the final date of the investment. Moreover, the payment is not immediate. The process takes on average 57 days, which can extend to 154 days in extreme cases. During this time, the money remains idle, yielding nothing.

The Impact of Delays on Real Return
This detail completely alters the final calculation. A CDB that promised 20% per year may yield only 13.19% per year with an average delay of two months. If reimbursement takes five months, the real return drops to around 8%, far below what was expected. In other words, the risk lies not only in the security of the capital but also in the trapped liquidity and the loss of promised returns.
These smaller banks can pay such high rates because they need to raise costly funds to finance risky operations, often linked to low liquidity assets like court orders. This increases the likelihood of instability and raises the chance that the investor will face the very scenario of waiting for the FGC.
New Rules Aim to Reduce Systemic Risk
In light of this scenario, the National Monetary Council (CMN) approved changes to the FGC rules starting in June 2026. Among them:
- Higher Contribution to the FGC: banks that raise more than 60% of their resources under the fund’s guarantee will have to pay double contributions (0.02%).
- Public Securities Requirement: if fundraising exceeds ten times the net worth, the excess must be invested in Treasury Bonds, which are considered safer.
These measures seek to limit the risk appetite of smaller institutions, but they do not eliminate the issue of delays.
Is It Worth Investing in CDBs from Small Banks?
The answer depends on each investor’s profile. Those seeking high returns at any cost may be attracted to the “Miraculous” CDBs, but need to be aware that the promised gain may never fully materialize. On the other hand, those prioritizing security and predictability should consider that the liquidity risk outweighs the advertised rate.
In summary: the FGC protects capital but does not guarantee the promised profitability. Therefore, it is essential to evaluate whether it is worth taking this risk in exchange for a few additional percentage points.
The case of the “Miraculous” CDBs illustrates how promises of returns can hide little-discussed traps. The capital may be protected, but the waiting time until reimbursement can drastically reduce the real return.
And you, would you risk investing in “Miraculous” CDBs from small banks in exchange for promises of 20% per year? Or do you prefer to invest in larger institutions with less risk of headaches? Leave your opinion in the comments — we want to hear your practical view on this dilemma.
