Dollar accounts: your options and how they differ
A dollar account is any account that holds a balance in US dollars instead of your local currency. The phrase covers very different products: a deposit at a bank in your country, an account at a bank abroad, an app that holds your money through a partner, or a balance in a dollar stablecoin such as USDC.

Four products under one name
The label tells you the currency, not the product. Three questions separate them: who holds the money, what protects it if that institution fails, and what it costs to put money in and take it out. The answers differ by country, and they matter more than the interest rate or the app’s design.
A dollar account at a bank in your country
In Argentina, dollar accounts at local banks are common. Under the central bank’s rules from April 2025, dollars that individuals buy through a bank are delivered as banknotes or credited to a foreign-currency account in the buyer’s name. The deposit stays in a regulated Argentine bank, in dollars.
In Mexico, dollar checking accounts for individuals are restricted. Banamex’s requirements, for example, ask for an address within 20 kilometers of the northern border or in Baja California or Baja California Sur, with exceptions for some foreign officials. Most people elsewhere in Mexico cannot open one.
In Brazil and Colombia, ask which institution holds the money, and in which country, before you open anything sold as a dollar account. A product marketed locally can be held abroad through a partner, which changes who protects your money and which rules apply.
An account abroad, opened directly or through an app
An account at a US bank is a dollar deposit in the US banking system. When the bank is insured, FDIC deposit insurance protects deposits up to its limits if the bank fails. It does not cover investments, crypto-assets, or the failure of a company that is not a bank. Opening an account directly usually requires documents and a relationship that many people abroad do not have.
Apps that offer dollar accounts to people in Latin America often hold the money at a partner bank or payment company. Read whose name the account is in, whether your balance counts as a deposit at an insured bank, and what the app charges to receive, convert, and withdraw. Those answers decide the protection you actually have.
A balance in a dollar stablecoin
A dollar stablecoin such as USDC is a token designed to keep a value of one US dollar, backed by its issuer’s reserves. Circle, which issues USDC, reports that most reserves sit in a government money market fund, with the rest held as cash at banks. It is not a bank deposit, and no deposit-insurance scheme covers it.
In exchange, it works without a foreign bank account. You can hold small amounts, move them at any hour, and keep them in a self-custodial account that only you control. The risks are the issuer, the technology, and being able to convert back to local currency when you need it.
Which kind of dollar account fits you?
Start from the job the money has to do. Dollars you will spend at home soon usually belong in local currency. Savings meant for a dollar expense, such as tuition or travel, fit any of the options. Income from clients abroad needs a way to receive transfers, which narrows the choice. The table sets out what to check; it is not a ranking.
Then compare the way out as carefully as the way in. An account that is cheap to fund can be expensive to leave, and a dollar balance is only useful if you can turn it into the payment you need: pesos or reais at home, a transfer to a university, or cash for a trip. Ask for the full cost in both directions before choosing.
| Option | Who holds the money | What to check first |
|---|---|---|
| Local bank, in dollars | A bank in your country. | Eligibility, account fees, and the deposit protection that applies. |
| Bank abroad | A foreign bank. | Opening requirements, transfer costs in both directions, and tax reporting at home. |
| App with a partner bank | A partner bank or payment company. | Whose name the account is in, and whether your balance is an insured deposit. |
| Dollar stablecoin | Your own wallet, or a platform. | The issuer, who controls the wallet, and the cost of converting back. |
Lex as a dollar account
Lex is an account for holding digital dollars. Your US Dollar balance is USDC in a self-custodial account: transactions need your approval with a passkey, and Lex cannot move your money on its own. It is not a bank account, it pays no interest, and no deposit insurance covers it.
You can add money in two ways. In Mexico, Brazil, and Argentina, a local transfer by SPEI, Pix, or CVU arrives as a local-currency balance that you convert to US Dollar with a quote; Lex charges no fee for the conversion. From abroad, Bridge issues account details for you that receive US dollars by ACH or wire, euros by SEPA, and pounds by Faster Payments, and the money arrives as USDC. Lex charges 0.25% on those transfers, plus any provider costs.
In Colombia, pesos sent by Bre-B arrive as wCOP, which cannot yet be converted to US Dollar in the app. The routes, fees, and limits for your account appear in the app before you confirm.
An example: saving for a degree abroad
Illustrative example. Daniel lives in Guadalajara and plans to start a master’s degree in Canada in two years, with fees in dollars. He asks his bank for a dollar account and learns that it requires an address near the northern border, which he does not have.
He looks at an account abroad, but opening one would need documents he cannot easily provide, and each international wire would carry fees at both ends. He reads the terms of an app that offers a dollar account and finds that his money would sit with a partner company abroad, with its own fees.
Daniel decides to convert part of each month’s savings into USDC after a SPEI transfer, and to keep his emergency money in pesos. Before starting, he writes down the full round-trip cost. He accepts that his dollars depend on the issuer rather than on deposit insurance, and he checks in advance how he will pay the university when the time comes.
