If the bank issuing your CDB fails, Brazil's Credit Guarantee Fund (FGC) steps in to return your money—but only up to a specific limit per investor and only for eligible products. Understanding these coverage boundaries marks the difference between truly secure fixed-income investments and those that merely appear safe.
How Does the FGC Work?
The FGC (Fundo Garantidor de Créditos) is a private deposit guarantee mechanism created jointly by financial institutions in Brazil to pay back depositors if a member bank fails. When the Central Bank of Brazil closes a participating institution, the FGC reimburses clients for their balances in covered products, up to a set ceiling per tax ID (CPF for individuals or CNPJ for corporations) at each institution. Any amount exceeding this cap is not automatically lost, but it becomes an unsecured claim in the bank's bankruptcy estate.
The FGC is not a government entity and receives no taxpayer funding. It operates as a private, non-profit organization financed by mandatory contributions from member financial institutions, scaled to the volume of deposits they hold. Operating rules are established by the National Monetary Council (CMN), while the Central Bank monitors the system. The framework serves a clear economic purpose: if a mid-sized bank collapses and depositors lose everything, panic can spread quickly, triggering bank runs across the broader system. The FGC exists to halt systemic contagion before it starts.
The FGC functions as capped deposit insurance, not a blanket guarantee on everything labeled "fixed income."Coverage limits are set by FGC regulations and subject to revision. Always verify the current rules in effect.
This coverage cap has two distinct tiers. There is a maximum limit per financial institution, as well as an aggregate global cap that limits the total amount an investor can receive from the FGC over a multi-year period, even across failures at multiple institutions. Both thresholds are detailed in the fund's official regulations on its website. Because these terms can change over time, investors should check the current rules directly before building their portfolios rather than relying on memory. However, knowing the coverage limit is only half the equation—the other half is understanding which products are actually insured.
Which Investments Are Covered by the FGC, and Which Are Excluded?
The fundamental criterion for coverage is straightforward: the FGC covers bank debt owed to you. When you purchase a bank certificate of deposit (CDB) or real estate/agribusiness credit notes (LCI or LCA), you are extending credit to the bank, and that specific debt obligation carries FGC protection.
Any instrument that is not a direct liability of a member bank falls outside FGC coverage. Brazilian Treasury bonds (Tesouro Direto) do not use FGC protection because the debtor is the federal government itself—a distinct class of sovereign risk. Corporate bonds (debêntures) and real estate or agribusiness receivables certificates (CRIs and CRAs) are issued by non-financial corporations or securitization firms, not banks. Mutual funds, real estate investment funds (FIIs), and fixed-income funds are also excluded: as a fund investor, you own units in a segregated pool of assets rather than holding a direct claim against a bank balance sheet.
- Checking and savings accounts
- CDBs and RDBs
- LCIs and LCAs
- Bills of exchange (LC), mortgage bonds, and LIGs
- Tesouro Direto (backed by the federal government)
- Debêntures, CRIs, and CRAs
- Mutual funds, FIIs, and private pension plans
- Equities, COEs, and crypto assets
A common point of confusion involves instruments bought through brokerage platforms: a CDB purchased via a broker remains fully insured by the FGC. The brokerage acts purely as an intermediary, while the underlying debtor remains the issuing bank named on the certificate. This distinction makes FGC coverage particularly relevant for investors buying paper from smaller banks through open platforms. Our guide on how to invest in CDBs, evaluate liquidity, and analyze issuer risk explains where to identify the issuing institution before deploying capital.
If the brokerage firm itself fails, a completely different framework applies. Securities, stocks, and fund units are registered directly under the investor's tax ID (CPF) at the B3 exchange or with the issuer's custodian, kept completely separate from the brokerage firm's assets. Consequently, these assets do not enter the brokerage's liquidation estate; they simply need to be transferred to another custodian. Uninvested cash sitting in a brokerage account, however, is a separate matter, making it prudent not to leave unallocated balances idle. This brings us to the worst-case scenario: what happens when an issuing bank fails?
A Bank Fails: What Happens to Your Money?
First, your capital is locked up. This delay often surprises investors who place total faith in FGC protection. While the guarantee functions as intended, payout is not immediate: several administrative procedures take time between a bank's closure and final reimbursement.
This process carries two important practical consequences. First, interest calculations stop on the date of the intervention decree. If your CDB held a fixed yield through maturity, any future unaccrued interest is forfeited, requiring you to reinvest returned capital at prevailing market rates, which may be lower. Second, capital remains inaccessible while claims are processed. As a result, FGC coverage should not justify placing emergency reserves in financially weak banks: insurance recovers the principal, but not on the exact day you might need cash.
Investors must also watch a key aggregation rule that often undermines intended diversification: banks belonging to the same financial conglomerate are treated as a single institution. Splitting deposits across different brand names owned by the same group does not double your coverage limit. Before allocating capital, confirm that issuing banks belong to entirely separate corporate entities. This leads to the ultimate practical question: how should you construct a portfolio with FGC rules in mind?
How to Use FGC Protection Strategically in Your Portfolio
Treat the FGC limit as the maximum exposure ceiling for any single mid-sized or smaller bank. If your allocation to a financial group exceeds that threshold, divide capital across issuers in distinct financial conglomerates so that each position fits entirely within guaranteed limits. Remember to calculate this threshold using expected future value—principal plus interest projected to accrue by maturity—rather than just the initial deposit. Finally, keep emergency reserves in instruments free from administrative liquidation risk, such as post-fixed Treasury bonds or daily-liquidity accounts at major tier-one banks.
Yield spreads offer valuable risk signals. When a smaller bank offers CDB yields significantly above rates paid by major institutions, it does so to attract funding that it cannot easily secure elsewhere. FGC protection does not erase underlying credit risk; it simply limits potential losses for allocations kept strictly under the coverage cap. Above that limit, any extra yield premium represents an unhedged bet on the financial health of the issuing bank.
Investors seeking to eliminate bank credit analysis altogether can utilize Tesouro Direto, where the debtor is the federal government and no coverage cap applies. However, fixed-rate and inflation-linked government bonds carry mark-to-market price volatility prior to maturity. Our analysis on navigating fixed-rate, IPCA+, and Selic-linked Treasury bonds details how price fluctuations impact investors who sell before maturity. Weighing these trade-offs helps determine how to balance capital between bank paper and sovereign debt.
The practical rule: The FGC protects investors holding eligible bank products, provided allocations stay below the individual institution cap and avoid concentrated exposure within a single financial group. Beyond covered bank products—such as debêntures, CRIs, CRAs, and mutual funds—or for balances above the cap, your protection relies entirely on the creditworthiness of the issuer. Before committing funds, confirm three elements: whether the security is FGC-eligible, whether the projected final balance fits within current regulatory limits, and whether you could tolerate temporary illiquidity while a claim is processed.
