Trump Rejected the CBDC. But He Didn’t Reject the Digital Dollar.

The United States is moving toward digital money. The real question is what kind of digital money America will use, who will issue it, and what will sit behind it. President Donald Trump made his position on one possible answer very clear: he did not want the Federal Reserve creating a U.S. central bank digital currency.

In January 2025, Trump signed an executive order titled “Strengthening American Leadership in Digital Financial Technology.” The order prohibited federal agencies from taking action to establish, issue, or promote a Central Bank Digital Currency, commonly called a CBDC. It also directed agencies to terminate ongoing federal plans or initiatives related to creating one.
That was a significant policy decision. A CBDC would essentially be a digital form of central-bank money. Depending on how it was designed, the Federal Reserve could potentially play a much more direct role in the digital monetary and payment system used by individuals and businesses.

But Trump did not reject digital dollars. In the very same executive order that opposed CBDCs, his administration explicitly supported the development and growth of legitimate dollar-backed stablecoins.
That distinction is important.

A CBDC and a dollar-backed stablecoin might both allow dollars to move digitally, but the architecture behind them is very different. With a CBDC, the central bank issues the digital currency. With a stablecoin, a private company issues a digital token designed to maintain the value of one U.S. dollar while operating under a regulatory framework.

Trump took that policy considerably further in July 2025 when he signed the GENIUS Act into law. The legislation established a federal regulatory framework for payment stablecoins and set requirements concerning who can issue them and the reserves supporting them.
This is where the story becomes much bigger than cryptocurrency.

Dollar-backed stablecoins need reserve assets supporting the tokens in circulation. Under the new framework, those reserves can include dollars and short-term U.S. Treasury securities. That creates a potentially important connection between the growth of digital dollars and demand for U.S. government debt.

Imagine the global stablecoin market eventually growing into the trillions of dollars. Those digital dollars would require enormous reserves behind them. If substantial portions of those reserves are held in short-term Treasury securities, increasing stablecoin adoption could translate into increasing demand for Treasuries.
Treasury Secretary Scott Bessent has publicly discussed this relationship. The administration sees regulated dollar-backed stablecoins not merely as another cryptocurrency product, but as a potential mechanism for expanding the reach of the U.S. dollar internationally while also creating additional demand for Treasury securities.

That reveals a much larger strategy.
Instead of the Federal Reserve issuing a digital dollar directly to Americans, regulated private companies can issue dollar-backed stablecoins. Those stablecoins can travel across modern digital financial networks around the world, while dollars and Treasury securities sit behind them as reserves.

The dollar becomes digital without requiring the Federal Reserve to create a retail CBDC.
There is another important piece of Trump’s policy that often gets overlooked. His January 2025 executive order also explicitly supported lawful participation in open public blockchain networks, including developing software, mining, validating transactions, conducting transactions with other people, and maintaining self-custody of digital assets.

In other words, the administration’s position was not that digital money or blockchain technology itself should be stopped. The distinction was about the architecture surrounding that technology.

The emerging policy can therefore be understood fairly simply: reject a Federal Reserve CBDC, establish rules for privately issued dollar-backed stablecoins, protect lawful participation in public blockchain networks, and allow private-sector digital financial infrastructure to develop within a regulatory framework.

There is an important limitation to remember. Trump’s executive order does not permanently prevent a future Congress and president from authorizing a CBDC. Congress has separately considered legislation intended to restrict the Federal Reserve’s ability to issue one. So saying Trump permanently eliminated the possibility of a U.S. CBDC would go further than the facts support.
But what Trump did accomplish is significant. His administration formally rejected pursuing a CBDC while simultaneously promoting an alternative model for digital dollars—and Congress subsequently created a federal stablecoin framework that moved that alternative much closer to reality.

This is why the bigger story isn’t simply that America rejected digital currency.

America isn’t rejecting digital money at all.

It is choosing an architecture for it.
Government establishes the regulatory framework. Private institutions issue regulated stablecoins. Dollars and Treasury securities provide reserves behind those stablecoins. Digital networks move them around the world. Public blockchains remain available. And the Federal Reserve doesn’t have to issue a retail digital currency directly to the American people.

That system could eventually accomplish many of the things people once expected a “digital dollar” to accomplish without actually creating a Federal Reserve CBDC.

Trump didn’t reject the digital dollar.

He rejected one architecture for the digital dollar—and helped establish the legal foundation for another.

Casa Morello 🍋 Sicilian products, exported worldwide. Rooted in Mondello, built on 20 years of bringing Italy abroad. Producers & buyers: let's talk.

My name is Francesco Morello. I'm Sicilian, and for twenty years I've lived in Seoul, importing Italian food and building bridges between Italy and Korea.
Along the way I learned something simple: the world wants Sicily. Our olive oil, our citrus, our pistachios, our wine. But many of the small producers who make the best of it have no path to buyers abroad.
Casa Morello is that path. An export house, rooted in Mondello, connecting Sicilian producers with importers, distributors and restaurants worldwide. We handle the bridge so the people who make it can keep making it.
