Circle President Tells Congress Stablecoins Can Strengthen Dollar Dominance

Stablecoins as a Tool for U.S. Dollar Statecraft

Heath Tarbert, the president of Circle, told Congress on September 2, 2026, that stablecoins could help protect the global role of the U.S. dollar. Stablecoins are digital assets designed to maintain a steady value by being pegged to a currency like the dollar. Tarbert argued that putting these assets under U.S. regulations would strengthen the network effects that keep the dollar as the world's primary currency.

The testimony suggested that regulated stablecoins can expand the use of the dollar in private digital payments. This shift could change how stablecoin issuers hold their reserves and increase the global demand for short-term U.S. government debt.

Important Figures in the Stablecoin Market

• Stablecoins currently account for less than 1% of all outstanding U.S. Treasuries.
• About 98% of the stablecoin market is denominated in U.S. dollars.
• The total market capitalization of stablecoins reached $317 billion in April 2026.
• Tether and Circle have increased their Treasury bill holdings by $70 billion since 2022.

Circle President Addresses Congressional Committee

Tarbert told lawmakers that digital asset rules could turn stablecoin infrastructure into a tool for American statecraft. However, he noted that technology alone cannot save the dollar's status if economic policies are not sound. He emphasized that while stablecoins can spread private use of the dollar, central banks will still make their own independent decisions about which currencies to hold in their official reserves.

The Impact of Proposed Legislation

Two major pieces of legislation, the GENIUS Act and the CLARITY Act, are shaping the future of digital assets in the U.S. The GENIUS Act, enacted in July 2025, requires stablecoin issuers to have one-to-one reserves, provide clear disclosures, and follow financial-crime laws. The CLARITY Act aims to set rules for market intermediaries and divide oversight between different government agencies.

Data Confirms Current Dollar Trends

Data from the International Monetary Fund shows that the U.S. dollar made up 57.13% of global foreign exchange reserves in early 2026. While the dollar's official share has seen a long-term decline, recent valuation changes caused a slight quarterly increase. Research from the Bank for International Settlements suggests that stablecoins will mostly affect private savings and payments rather than the official reserve choices of central banks.

Understanding the Risks and Uncertainties

There is still an ongoing debate about whether the widespread use of stablecoins will lead to financial problems. Some experts worry that high adoption could cause "runs" where many people try to withdraw money at once, or lead to financial contagion. It is also unclear if the increased demand for Treasury bills from stablecoin issuers will have a significant impact on the broader government debt market.

The Timeline for New Regulations

The general rules of the GENIUS Act are expected to take effect on January 18, 2027. Following this, a broader ban on payment stablecoins from unlicensed issuers is scheduled to start on July 18, 2028. These deadlines will force issuers to move toward high-quality liquid assets to support their tokens.
