GENIUS Act: the US stablecoin law and Brazil

In July 2025, the US passed the GENIUS Act, a federal stablecoin law. In Brazil, the Central Bank began treating stablecoins as foreign exchange.

On July 18, 2025, the President of the United States signed the GENIUS Act, the federal law that creates rules for payment stablecoins, digital currencies pegged to the dollar. The law requires 100% reserves in liquid assets, such as dollars and short-term Treasury bills, and monthly public disclosure of the composition of those reserves. In Brazil, the Central Bank took a different path and began treating part of stablecoin operations as foreign exchange operations.

What happened

The GENIUS Act was passed by the U.S. Senate on June 17, 2025, by 68 votes to 30, and by the House on July 17, by 308 to 122. The next day, it became Public Law 119-27. The BBC and The New York Times reported its passage as the first major national crypto legislation in the United States.

According to the White House's official fact sheet, the law requires every payment stablecoin to be fully backed by approved liquid assets, with monthly public reports on reserves. Issuers become subject to U.S. bank secrecy law, with programs against money laundering, sanctions compliance and customer identification, and must have the technical ability to block or freeze coins by lawful order. Marketing may not suggest that the stablecoin is backed by the government or federally insured. If the issuer becomes insolvent, stablecoin holders have priority over other creditors.

In Brazil, the response came through the regulator. On November 10, 2025, the Central Bank published Resolutions 519, 520 and 521. Resolution 521 classified operations with assets referenced to fiat currency, stablecoins, and international transfers with virtual assets as foreign exchange market operations, according to Agência Brasil.

Why it matters

Stablecoins have become, in practice, a means of payment between countries. Companies use them to pay suppliers abroad, people use them to send money to family, and exporters receive in minutes what used to take days. What was missing was rules.

The two choices show two perspectives on the same instrument. The United States looks at the issuer: it defines what a reliable payment stablecoin is and who can issue it. Brazil looks at the flow: when value crosses the border, it follows foreign exchange rules, with reporting to the Central Bank. For those engaged in foreign trade, the two rules add up.

There is also a geopolitical effect. By requiring backing in U.S. Treasury securities, the law expands demand for U.S. debt and reinforces the role of the dollar. Exporting countries, such as Brazil, now deal with a regulated digital dollar circulating in global trade.

In Bairo's view

Bairo Leandro Gonzalez Martinez designed CEASA Bank with in mind those who buy Brazilian food on the other side of the world. In his reading, the regulation of stablecoins in the United States and in Brazil takes digital payments between countries out of the gray zone and places them in the infrastructure that connects agribusiness to the world.

For Bairo, a regulated stablecoin is a tool, not a promise. It serves so that the invoice for a shipment is paid quickly and with a trail, and what matters is that the grower gets paid and the shipment moves on. In his view, the time an exporter spends waiting for a payment confirmation is lifetime that does not come back, and shortening that wait is technology's reason for being.

He carefully separates things the market tends to mix up. A stable coin serves to pay. A public record network serves to prove what happened. BICOIN is not a stablecoin, has no parity with any currency and is not presented as a store of value.

Where this meets the ecosystem

The design of CEASA Bank, an agribusiness financial platform that operates on the infrastructure of an authorized institution, provides for payment of a shipment's invoice by bank deposit or by stablecoins, always with authorized institutions in each country and within each country's foreign exchange rules.

The BTZ Chain is a public network, which anyone can check in the explorer, proposed to record facts with proof that there is a real person behind each act. BICOIN is this network's governance coin, with the yardstick "1 BTZ = 1 minute of human life": it measures purpose, has no promised price and is not an invitation to buy.
