Stablecoins Surpass Nations as Major U.S. Treasury Holders After GENIUS Act

TLDR:

• Tether holds $141B in U.S. Treasury exposure, ranking it 17th among all global government debt holders.
• The GENIUS Act legally requires stablecoin issuers to back every token with T-bills or dollar equivalents.
• China cut $86B in Treasury holdings as Japan signals drawdown, opening demand gaps stablecoins now fill.
• Apollo projects the stablecoin market could hit $2 trillion by 2028, potentially surpassing Japan’s Treasury position.

Stablecoins have quietly become a structural component of U.S. monetary policy. Tether and Circle now hold over $160 billion in U.S. Treasury securities combined.

That total places both companies above sovereign nations, including South Korea, Germany, and Saudi Arabia. A decade ago, neither existed in any meaningful financial capacity. Today, they rank among the most consistent buyers of American government debt on the planet.

The GENIUS Act Turned Stablecoin Reserves Into a Treasury Buying Mandate

The GENIUS Act, signed into law last year, reshaped how stablecoin issuers manage their reserves. The legislation requires each stablecoin token to be backed 1:1 with verified reserves.

Those reserves must be held in U.S. dollars, Treasury bills, or short-duration equivalent instruments. Congress did not only regulate stablecoins as it also created a legal mandate to buy Treasuries at scale.

Tether currently holds $141 billion in total U.S. Treasury exposure under this structure. Of that amount, $122 billion is held directly in T-bills.

The remaining portion is parked in overnight reverse repurchase agreements. That positions Tether as the 17th largest holder of U.S. government debt worldwide.

Circle’s USDC adds another $24.5 billion in Treasury reserves to the broader picture. About 93% of Circle’s total reserves sit in overnight repos and short-term government securities.

As TFTC noted on X, “Congress didn’t just regulate stablecoins. It created a legal mandate to buy Treasuries at scale.” Together, both issuers have become a growing class of captive Treasury buyers.

Tether also reported $10 billion in profit through the first three quarters of 2025. That result surpassed Bank of America’s earnings for the same period.

It also nearly matched figures posted by both Goldman Sachs and Morgan Stanley. Tether reached that level with a workforce of approximately 300 employees.

Stablecoins Fill the Demand Gap as Traditional Foreign Buyers Pull Back

China reduced its Treasury holdings by $86 billion over the past year. Its current position has fallen to the lowest level recorded since 2008.

Japan, the largest foreign holder at $1.2 trillion, is also signaling a slow drawdown. The traditional foreign buyer base for U.S. government debt is gradually narrowing.

Stablecoins are absorbing a share of that demand in real time. Every dollar minted as USDT or USDC creates automatic buying pressure for U.S. government securities.

The dollar also gets distributed globally through crypto payment rails. This mechanism extends dollar dominance without relying on traditional diplomatic or military tools.

Apollo estimates the stablecoin sector could reach $2 trillion by 2028. At that scale, stablecoin issuers would hold more Treasuries than Japan currently does.

TFTC stated that “the U.S. government now has a structural incentive to grow the stablecoin market.” That incentive is now embedded directly into federal legislation.

The growth of stablecoins serves both crypto markets and the broader U.S. fiscal structure. Each new token minted adds to Treasury demand in a measurable and automatic way.

This dynamic was not present in any meaningful form just five years ago. Stablecoins now function as one of the most reliable buyers of American sovereign debt.
