Before talking about returns, investment contracts, or any other allocation strategy, there is a conversation I need to have with anyone just starting out: do you have an emergency fund?
That question is not rhetorical. Serasa data shows that 81.7 million Brazilians are currently carrying overdue debt. That represents nearly half of the country's adult population. When I look at that number, I do not see just a statistic — I see a portrait of someone who had to put a car repair on a credit card, of someone who paid rent in installments after an unexpected job loss, of someone who took out a loan at 8% per month because they had no other option.
Overdue debt, in most cases, does not begin with irresponsible spending. It begins with the absence of a protective layer that all of us need to have in place before thinking about anything else.
Why the Emergency Fund Comes Before Everything
Brazil's national statistics agency (IBGE) reports that the average Brazilian saves just 2.3% of their income. By comparison, countries like Germany and South Korea have savings rates above 10%. That number reflects a financial culture still developing, but it also reflects a vicious cycle: without a cushion, any unexpected expense becomes debt; with debt, there is less left to save; with less to save, the emergency fund never gets built.
When someone asks me whether to invest before building an emergency fund, my answer is direct: no. The logic is simple. If you invest R$5,000 in any product with limited liquidity or a fixed term and then lose your job or face a medical emergency two months later, you will either cash out early — probably at a loss — or turn to expensive credit.
An emergency fund is not an investment. It is financial infrastructure.
How Much to Save: The Monthly-Expenses Rule
The standard recommendation is to accumulate between three and six months of your total monthly expenses. But that range needs to be calibrated to your situation.
Three months is sufficient for someone with a formal employment contract, benefits like Brazil's FGTS severance fund and unemployment insurance, stable income, and predictable fixed expenses.
Six months or more is recommended for self-employed workers, freelancers, entrepreneurs, people with variable income, or anyone with financial dependents and no other source of support.
To calculate your target, add up all your fixed and variable monthly expenses: rent or mortgage, food, transportation, health insurance, school fees, utility bills, leisure. Add everything up, multiply by the number of months in your target range, and that is your goal.
If you spend R$4,000 a month and have a formal employment contract, your target is R$12,000 to R$24,000. If you are self-employed with the same expenses, consider R$24,000 to R$36,000.
Where to Keep It: Non-Negotiable Criteria
An emergency fund has three requirements that cannot be compromised: immediate liquidity, low risk, and returns that preserve purchasing power.
There is no room here for stocks, real estate investment funds, crypto, or any product with volatility or delayed redemption. The goal is not to maximize returns. The goal is to have the money available when you need it, without surprises.
With those criteria in mind, two options stand out clearly in 2026.
Tesouro Selic
Tesouro Selic is the most suitable instrument for an emergency fund in Brazil. It is issued by the federal government — the lowest-credit-risk issuer available — and carries D+1 liquidity: you request the redemption today and the money hits your account the next business day.
With the Selic at 14.75% per year, Tesouro Selic delivers returns close to the benchmark rate, minus B3's 0.20% annual custody fee for balances above R$10,000. For those starting out with less than that threshold, the fee does not apply.
The one caveat is IOF (financial transaction tax) on redemptions within the first 30 days: the rate starts at 96% on day one and steps down progressively to zero on day thirty. Tesouro Selic therefore works best as a structured reserve, not as a checking account.
Daily-Liquidity CDBs
The other highly relevant option is daily-liquidity CDBs issued by banks and fintechs. With the Selic at 14.75%, the most competitive CDBs are paying between 100% and 110% of CDI, which works out to roughly 1.15% per month gross, or approximately 0.97% per month net of income tax for applications held up to six months.
Daily liquidity means the redemption can be made at any time, generally with same-day or next-business-day credit depending on the institution.
The risk of CDBs is the credit risk of the issuing bank. For that reason, prioritize issuers covered by the FGC (Fundo Garantidor de Créditos), which protects up to R$250,000 per taxpayer ID per institution. Virtually all banks and fintechs operating in Brazil are FGC members.
What to Avoid in an Emergency Fund
Some common choices that seem reasonable but undermine the fund's purpose:
Savings accounts (poupança): when the Selic is above 8.5%, the poupança pays only 0.5% per month plus a reference rate — significantly below inflation in 2026. With the Selic at 14.75%, poupança returns less than 60% of what Tesouro Selic or a good CDB delivers.
Non-interest-bearing checking account: money sitting idle loses purchasing power every day. There is no justification for keeping the emergency fund in a non-yielding account when daily-liquidity CDBs are available with a few taps on your phone.
Fixed-income funds with settlement delays: some funds take D+1 to D+30 to release redemptions, which can be a serious problem at exactly the moment you most need the money.
Volatility-linked products: Tesouro IPCA+, for example, has mark-to-market price swings on Tesouro Direto. An exit at an unfavorable time can produce a nominal loss. Not appropriate for an emergency fund.
How to Build the Fund in Practice: Step by Step
Step 1: Calculate your target. Add up your monthly expenses and multiply by your target number of months. Write down that number. It is your destination.
Step 2: Open an account with access to Tesouro Direto or daily-liquidity CDBs. Any licensed brokerage offers access to Tesouro Direto. Fintechs such as Nubank, Inter, C6, PicPay, and others offer their own daily-liquidity CDBs directly in the app.
Step 3: Set a fixed monthly contribution. The most important factor is not the initial amount — it is consistency. Even if it is R$200 a month, the habit of contributing regularly compounds over time. Over 12 months, R$200 per month earning 1% per month totals approximately R$2,530.
Step 4: Automate. Set up an automatic transfer on the date you receive your paycheck, before any other spending. Saving what is left over rarely works. Spending what is left over after saving is what works.
Step 5: Do not touch the fund for predictable expenses. A planned vacation, a phone upgrade, or a home renovation are not emergencies. If you use the reserve for non-emergency expenses, you will have to rebuild it when the real emergency arrives.
Step 6: Rebuild immediately after using it. If you had to draw R$3,000 from the fund, return to your monthly contribution plan with the focus of restoring that amount before directing money anywhere else.
The Emergency Fund and the Decision to Invest
Once the fund is in place, you have something most people do not: choice. You can invest without liquidity pressure, tolerate long-term volatility more easily, and take advantage of opportunities without being forced to sell at the worst time.
It is only from a fully built emergency fund that it makes sense to consider longer-duration products, higher return potential, and more sophisticated allocation structures.
At Royal Binary, investors who arrive with their financial foundations organized make decisions with much more clarity. Not because the product changes, but because your mindset changes when you are not operating under financial survival pressure.
If you do not yet have an emergency fund, that is priority number one. There is no shortcut here. But the path is straightforward: a defined target, the right product, consistent contributions, patience.
When that foundation is in place, explore what Royal Binary has to offer as the next step in your investment journey.
