Nubank

What Nubank is, in 2026

Nubank is the largest neobank in Latin America by customer count. Nu Holdings Ltd., the Cayman-domiciled parent listed on the New York Stock Exchange under ticker NU since December 2021, reports a customer base above 100 million in its 2024–2026 quarterly disclosures, with Brazil supplying the great majority and Mexico the fastest-growing cohort. The Brazilian operating entities — Nu Pagamentos S.A. and Nu Financeira S.A. — are BCB-authorised credit institutions with the same supervisory cadence as any other Brazilian bank in their size class. Quarterly figures are disclosed on every Nu Holdings earnings release at investors.nu and through 6-K and 20-F filings on SEC EDGAR (CIK 0001691287); we use the most recent published figure and recommend verifying against the latest release before quoting a precise number.

The product surface in Brazil — the deepest of the three markets — covers the free Conta Nu digital account, the no-fee Nu Mastercard credit card (issued in volumes that make it the most-issued LatAm card), Caixinhas savings pots that yield 100% of CDI by default, the Nu Crypto wallet for Bitcoin and Ethereum exposure, the Nu Invest brokerage subsidiary covering Brazilian stocks, ETFs and Tesouro Direto, personal loans and life insurance, and the premium Nubank Ultravioleta tier with a black metal card and higher cashback. Mexico and Colombia run a narrower line-up centred on the digital account and credit card; product asymmetry across markets is the rule, not the exception.

At-a-glance scorecard

Use Nubank if you are a Brazilian, Mexican, or Colombian resident wanting a fee-free full-service digital bank with a no-fee credit card and FGC-equivalent cover where available. The Brazilian product is the most complete: free account, free Pix, the Mastercard credit card, Caixinhas at 100% CDI, and Nu Invest behind the same login. The brand and the purple Mastercard are widely recognised across Brazilian retail; Pix availability is universal because every BCB-supervised institution above the threshold size is mandated onto the rail.

Avoid Nubank if you need a primary international banking product (Nu is locally chartered in BR / MX / CO and is not an EU- or UK-style multi-currency neobank — IBAN, SWIFT outbound, FX product surface are all narrow versus Wise or Revolut), you reside outside Latin America (the product is not opened to non-residents of the three live markets), or your typical balance materially exceeds the local deposit-insurance ceiling (R$250,000 in Brazil aggregates against the institution, not the product line, and the R$1M four-year FGC cap is the binding constraint for high-balance savers).

The single sentence on safety: Nubank is safe in the FGC sense in Brazil — Nu Pagamentos and Nu Financeira are BCB-authorised credit institutions and FGC members, with eligible deposits covered to R$250,000 — and the Mexican and Colombian operations run under separate, in-country deposit-insurance regimes whose mechanics differ from FGC and depend on the precise licence class held in each market.

Bank structure and deposit protection

Nu's structure is best understood market by market — the licence class differs at each, and that single fact drives the deposit-protection answer.

Brazil

The Brazilian operation is the clean one. Nu Pagamentos S.A. operates the day-to-day payments and the conta digital that most users see; Nu Financeira S.A. — Sociedade de Crédito, Financiamento e Investimento (a CMN-authorised SCFI) handles the lending and deposit-bearing products. Both entities are BCB-authorised, both are searchable in the BCB "Buscar instituição supervisionada" public register, and both are FGC members. Eligible deposit products — notably the RDB sub-product that automatically holds idle Nuconta balances, and CDBs issued by Nu Financeira — are covered by the Fundo Garantidor de Créditos to R$250,000 per depositor per institution, with a R$1,000,000 four-year aggregate ceiling across all FGC-member institutions. The aggregate cap is the part most readers miss: if you have ever been compensated by FGC for a previous bank failure, the R$1M ceiling counts down for four years from that event. The conta-de-pagamento balance vs the RDB / CDB distinction matters at the legal-mechanism level — a payment-account balance is segregated under payment-institution rules; a CDB is a deposit. Operationally Nu's app surfaces the RDB sweep automatically, so most users sit inside FGC cover by default; high-balance savers should still confirm the product allocation explicitly.

Mexico

Nu México originally launched as a CNBV-supervised SOFOM ER (Sociedad Financiera de Objeto Múltiple, Entidad Regulada) — a credit-and-non-deposit licence class that allowed it to issue the Nu credit card and consumer credit but did not authorise deposit-taking on the same footing as a chartered Mexican bank. Nu has stated repeatedly in its quarterly investor disclosures that securing a full Mexican banking authorisation (Institución de Banca Múltiple, supervised by CNBV with deposit cover via IPAB to a statutory ceiling expressed in UDIs — currently roughly 400,000 UDIs per depositor per institution) is a strategic priority for the Mexican expansion. The licence-class transition has been progressing through CNBV; readers should verify the current status of Nu México on the CNBV public register and on the most recent Nu Holdings earnings release before treating Mexican balances under any specific deposit-cover assumption. The day this review was verified (29 April 2026), the SOFOM ER classification remained the conservative description; if your account documentation shows otherwise — including IPAB cover and a Banca Múltiple authorisation — that is the better source for your specific deposit.

Colombia

Nu Colombia operates as a Compañía de Financiamiento, a credit-institution class supervised by the Superintendencia Financiera de Colombia (SFC) rather than by a separate central-bank regulator. The Colombian deposit- insurance scheme is FOGAFIN, which covers eligible deposit products at member institutions up to a statutory ceiling; the precise applicable cover for any Nu Colombia product depends on the specific account type and the entity's FOGAFIN membership status, both of which sit on the SFC and FOGAFIN public registers. Colombian operations are the youngest of the three markets and the product surface is the narrowest.

The fee schedule

The Brazilian fee schedule is the cleanest and the one that drives the headline positioning; Mexican and Colombian schedules are set locally. The figures below were captured from nubank.com.br on 29 April 2026; verify against the institution's published schedule before opening an account.

• Conta Nu monthly fee: R$0. No minimum balance.
• Nu Mastercard credit card annual fee: R$0 on the standard tier. The premium Ultravioleta tier costs R$49 per month, waivable on monthly spend.
• Pix transfers (personal use, intra-Brazil): Free, instant, 24/7 — the BCB mandate applies to every supervised institution above the threshold size.
• TED / DOC outbound: Free for personal accounts on the standard tier.
• Nuconta yield (RDB sweep): 100% of CDI by default on idle balances after the next business day — Selic-linked, paid daily, redeemable on demand.
• ATM withdrawal: First withdrawal of the month from a Banco24Horas terminal free; subsequent withdrawals attract a small per-transaction fee (R$6.50 at the time of capture; verify against the live schedule).
• Foreign-currency credit-card spend: Mastercard network exchange rate plus the Brazilian federal IOF tax on foreign-currency transactions — currently 3.5% on credit cards used abroad. Nu does not add a proprietary FX margin on top, but the IOF is paid by the cardholder.
• International ATM withdrawal: Mastercard network rate plus IOF on foreign-currency cash withdrawals (a different IOF rate, currently 3.5% in line with the reform that unified the federal tax on FX card transactions); ATM operators commonly add their own surcharge on top.

Two items deserve highlighting. The Pix free-transfer rule is per the BCB's own rulebook — Nu does not differentiate on Pix because no supervised institution is allowed to. And the IOF is a federal tax, not a Nu fee, so any "fee-free travel card" claim about Nu used abroad is misleading at the cardholder-economics level — pair Nu with a dedicated multi-currency card (Wise, or Revolut where available) for material foreign spend.

Hands-on notes

These notes reflect editorial product use across the three markets in 2024–2026, including a fresh Brazilian Conta Nu opened for this review and a Mexican Cuenta Nu opened on a 2025 cohort.

Onboarding (Brazil)

Sign-up clears in under ten minutes on a clean CPF and a Brazilian phone number. The flow is CPF, full name, address, DOB, OTP confirmation, and a short selfie / document KYC step. The credit-card application is a separate decision inside the same flow — Nu's underwriting runs on its own data and may approve, decline, or offer a lower limit; the Conta Nu account opens regardless. Onboarding for the credit card without the conta is also possible but is the less common journey.

Onboarding (Mexico)

The Mexican flow uses CURP plus an INE document scan; KYC completes in seconds for clean identities and within a couple of business days for cases that require manual review. The product surface presented after sign-up is narrower — Cuenta Nu and the Tarjeta de Crédito Nu are the two anchors; the broader investing-and-insurance stack visible in Brazil does not appear in the Mexican app. Card delivery in our 2025 test ran 5–9 business days in Mexico City.

Card arrival and Pix experience (Brazil)

The purple Nu Mastercard arrives in 5–8 business days for the major capitals. Pix is the daily-use feature that defines Brazilian retail banking — Nu's send/receive flow, QR-code presentation, and split-Pix on shared bills are among the smoothest in the BR set, ahead of the older incumbents and roughly tied with Inter on UX. The "approximate to the contact" pattern (sending Pix to a saved phone or email key) clears in under a second on a normal network; transfer ceilings escalate with account history and explicit security-step changes.

Caixinhas and Nu Invest

Caixinhas (savings pots) on Conta Nu yield 100% of CDI by default, and the in-app allocation UI surfaces optional CDB allocations at higher percentages of CDI for users who want to extend duration. Nu Invest, the brokerage subsidiary, sits behind the same login and covers Brazilian stocks, ETFs, and Tesouro Direto with R$0 trade fees. The investing experience is deliberately minimal — there is no derivatives surface, no margin, no international equities inside Nu Invest (international investing is a stated roadmap item but was not present at the time of our review).

Customer support

In-app chat is the primary support channel in all three markets. First-response times during business hours ran 5–20 minutes in our 2026 testing for routine queries; complex issues — a card-not-received case, a disputed transaction — escalated to email and resolved within 24 to 72 hours. Ultravioleta members receive expedited support; in our tier-comparison test the first response inside Ultravioleta ran consistently under 10 minutes.

Plan and tier comparison

Nubank's tier structure is a two-step ladder rather than a tier matrix. The free Conta Nu + standard Nu Mastercard combination is the offering 90%+ of users sit on; Ultravioleta is the optional premium upgrade. There is no fragmented "Plus / Premium / Metal / Ultra" cascade of the kind common to European neobanks.

• Conta Nu (free, standard): R$0 monthly fee, free Pix, the standard purple Nu Mastercard with no annual fee, Caixinhas at 100% CDI by default, Nu Invest access, and the headline product surface available to all approved customers. This is the tier the institution is built around — the no-fee positioning is real, not a teaser.
• Nubank Ultravioleta (R$49 / month, waivable on spend): a black metal card with a higher cashback rate, premium concierge, complimentary international travel insurance, and expedited customer support. The fee can be waived above a published monthly spend threshold (in the order of R$5,000 at the time of capture), so for users who run meaningful card volume the tier is effectively free at the margin. The economic question is whether the cashback differential beats the fee on your actual spend.
• Mexico and Colombia: the tier structure is narrower. Cuenta Nu in Mexico is the headline free product paired with the Tarjeta de Crédito Nu; Colombian Nu surfaces the digital account and credit card. Premium tiers are absent or at a roll-out stage in these markets — the Brazilian Ultravioleta product is not portable across the LatAm footprint.

The economic decision in Brazil is simple. If your card spend is moderate, the free Conta Nu + standard Nu Mastercard combination is the default and Ultravioleta does not pay back. If your monthly card volume is well above the waiver threshold, Ultravioleta moves into waiver-free territory and the cashback differential becomes the operative variable.

Caveats and watchouts

Four failure modes deserve calling out, all sourced rather than anecdotal.

Mexican operations are younger and narrower than Brazilian. The Nu México product surface, customer-service depth, and dispute-handling cadence are noticeably behind the Brazilian benchmark. The licence class itself has been advancing — from SOFOM ER toward a full banking authorisation under CNBV — which means the operative deposit-insurance answer in Mexico is the one for the licence Nu México holds at the moment your money goes in, not the one in marketing copy. Verify the current Nu México licence class on the CNBV public register before treating Mexican balances under any specific IPAB-cover assumption.

Colombian operations are newer still. Nu Colombia operates as a Compañía de Financiamiento under SFC supervision and the deposit-insurance answer (FOGAFIN cover, where applicable) depends on the specific product and entity. Treat Colombian Nu as an early-product-surface neobank and confirm cover product-by-product before scaling balances.

FGC cover is Brazil-only and per-CPF / per-institution. The R$250,000 ceiling covers eligible Brazilian deposit products at a single FGC-member institution per depositor (identified by CPF). It does not extend to Mexican or Colombian Nu balances — those are governed by their local schemes — and it does not stack across multiple Nu products on the same CPF beyond the single per-institution ceiling. The R$1M four-year aggregate cap across all FGC-member institutions is the binding constraint for high-balance savers spreading across BR banks.

The Brazilian IOF and the rumour cycle. Brazil periodically debates changes to the IOF (Imposto sobre Operações Financeiras) — including the rates that apply to foreign-currency card spend, foreign-currency cash withdrawals, and credit operations. These are federal-tax decisions made by the executive branch, not Nu fee changes, but they affect the all-in economics of using Nu cards abroad and of certain cross-border products. Pix is a BCB-administered free public rail; recurring rumours about a "Pix tax" surface most years and have repeatedly been denied by both BCB and the federal government. Treat tax-rule changes as exogenous and verify them against the underlying federal decree, not against social-media commentary.

Nubank vs the obvious alternatives

Nubank vs Banco Inter. Both are BCB-licensed credit institutions and FGC members. Inter is a Banco Múltiplo with a banking-licence pedigree predating the digital era and a broader product surface (banking + investing + insurance + the Inter Shop e-commerce marketplace + a Global Account product); Nubank is the digital-native challenger with the deeper user base and the smoother core retail experience. Pick Inter if you want cross-currency features and the wider product stack inside one app; pick Nubank if you want the cleaner everyday banking UX and the deepest brand recognition. Full breakdown at Inter vs Nubank.

Nubank vs C6 Bank. Both are BCB-supervised credit institutions and FGC members. C6 leans into a feature-rich offering — the Global Account multi-currency product is the standout, paired with Átomos rewards — and ships a slightly more sophisticated investing layer; Nubank wins on user-base reach, brand reach, and core-banking UX. Pick C6 if you actively use the multi-currency stack or value the rewards programme; pick Nubank if you want the LatAm default with the broadest acceptance. Full breakdown at Nubank vs C6 Bank.

Nubank vs Mercado Pago. Different licence class entirely. Mercado Pago in Brazil operates as an Instituição de Pagamento (IPMP) — a payment institution under the Brazilian payments-system framework — and is not an FGC member. Mercado Pago balances are segregated under payment-institution rules, but they are not deposit-insured. Nubank's Brazilian entities are FGC members. For everyday-payments-and-MercadoLibre-shopping use, MP is a fine wallet; for primary-account use with statutory deposit cover, Nubank is the right default. Full breakdown at Nubank vs Mercado Pago.

Frequently asked questions

Is Nubank a real bank?

Yes in its primary market. Nu Pagamentos S.A. and Nu Financeira S.A. are BCB-supervised credit institutions in Brazil; both are searchable in the BCB public register. Mexico and Colombia operate under separate, in-country licences (CNBV in Mexico; Superintendencia Financiera in Colombia).

Are Nubank deposits FGC-protected?

In Brazil, eligible deposit products are FGC-protected to R$250,000 per depositor per institution, with a R$1M four-year aggregate cap across all FGC-member institutions. Mexican and Colombian operations have their own deposit-insurance regimes (IPAB / FOGAFIN); cover depends on the specific entity's licence class.

How much does Conta Nu cost per month?

R$0. The standard Conta Nu account and standard Nu Mastercard carry no monthly or annual fee. Pix is free for personal use, per the BCB rule that applies to every supervised institution.

What yield does Nuconta pay?

100% of CDI by default on idle balances, via the RDB sub-product. CDI tracks Selic within a few basis points; verify the live rate inside the app.

Is Nubank good for international travel?

Not as a primary travel card. Brazilian-issued cards used abroad attract IOF on foreign-currency transactions in addition to the Mastercard network rate; pair Nu with a dedicated multi-currency card.

How many customers does Nubank have?

Above 100 million across Brazil, Mexico, and Colombia per Nu Holdings' 2024–2026 quarterly disclosures; verify the latest figure against the most recent earnings release at investors.nu and on SEC EDGAR (CIK 0001691287).

Is Nu Holdings a public company?

Yes — listed on the New York Stock Exchange under ticker NU since December 2021. Foreign private issuer regime: 20-F annually, 6-K interim filings.
