Mission Brief
A company incorporated in El Salvador, with no sovereign backing, no deposit insurance, and no full audit from a major accounting firm until late 2025, now holds more US Treasury bills than the governments of Canada, Germany, and South Korea — combined. Tether Holdings Limited, issuer of USDT, disclosed in its most recent attestation that it holds over $135 billion in US Treasuries, the bulk of it in short-dated T-bills, as collateral backing roughly $186 billion in stablecoin tokens in circulation. The position makes Tether one of the top twenty foreign holders of US government debt on the planet — ahead of most nations that have professional central banks, reserve management offices, and treaty relationships with Washington.
That number did not get there by accident. It got there because Washington needed a buyer, and Tether needed a law. The GENIUS Act, signed by President Trump in July 2025 after a 68-to-30 Senate vote, requires every regulated stablecoin issuer in the United States to hold reserves at a one-to-one ratio — cash, T-bills with maturities under 93 days, or overnight repurchase agreements backed by Treasuries. Treasury Secretary Scott Bessent called it "a surge in demand for US Treasuries." What he meant was: a private offshore company was going to be deputized as a buyer of American debt, without appearing on any foreign-holder registry that Congress examines.
As of June 8, 2026, the 3-month T-bill yield sat at 3.72% — 63 basis points below where it traded a year ago. Standard Chartered's digital asset research desk estimated in February that stablecoin growth alone could generate $800 billion to $1 trillion in incremental T-bill demand by 2028, against roughly $1.3 trillion in projected net new T-bill supply. That is not a demand surge. That is a structural capture of the short end of the US debt market by a sector that operates outside the Federal Reserve's supervisory perimeter.
By the time the Senate was voting, the operation was already running. The question was only whether Washington would formalize the arrangement or not. They did.
The Operation
The mechanics work like this: a user anywhere in the world — Lagos, Buenos Aires, Istanbul — transfers dollars to Tether, Tether mints USDT and credits the wallet, and the dollar goes directly into a pool that buys US T-bills through custodial banks and money market funds. The user never interacts with a US financial institution. The Treasury bill gets purchased. The dollar stays inside the American financial system. It is, structurally, a shadow reserve program — private actors in jurisdictions outside US regulatory reach performing the same function that foreign central banks performed for forty years under Bretton Woods II.
The parallel rail is Circle's USDC — $75 billion in circulation as of February 2026, growing at 73% annually in 2025 against Tether's 36% — and it operates on the same reserve logic, buying short-dated Treasuries, holding them through Bank of New York Mellon and BlackRock's Circle Reserve Fund. Between the two of them, Tether and USDC now account for 93% of total stablecoin market capitalization, which means 93% of roughly $300 billion in stablecoin reserves flows, one way or another, into instruments that either directly purchase US government debt or serve as collateral for overnight repo agreements backed by it. The T-bill market is $6.3 trillion. These two private entities have quietly claimed a structural share of it that most mid-sized sovereign wealth funds would envy.
Tether's US CEO confirmed in February that the company was targeting a top-ten position among all global T-bill holders — placing it alongside sovereign nations on a list that the US Treasury's TIC system publishes quarterly. As of that disclosure it was already in the top twenty. The TIC report does not list Tether by name. It routes through custodial structures that classify the holdings as private financial accounts, not foreign sovereign holdings. The visibility that Congress uses to track who is buying and selling American debt does not capture this position.
Senator Jack Reed of Rhode Island flagged the other side of the operation in February: Tether, because it is incorporated in El Salvador, is not subject to the GENIUS Act's full audit and reserve verification requirements. It operates under a foreign-issuer provision that allows it to continue offering USDT to Americans as long as Treasury deems its home jurisdiction's rules "substantially similar" to US standards. El Salvador's standards are not substantially similar to anything. Tether runs a parallel GENIUS-compliant token called USAT through Anchorage Digital Bank for the domestic market — the two tokens interoperate — but the $186 billion in USDT circulating globally faces no audit requirement that Washington can actually enforce.
Rules of Engagement
The Federal Reserve owns $4.2 trillion in Treasuries. The Social Security trust fund holds another $2.8 trillion. Japan holds $1.1 trillion. China holds $760 billion. And a private company in El Salvador now holds $135 billion — growing, by the trajectory of the stablecoin market, at a rate that could put it in the top ten within 18 months. That concentration of short-end demand is doing something specific to the yield curve: it is keeping 3-month T-bill yields suppressed relative to where they would price if the Federal Reserve were the only buyer at this scale. The 3-month bill at 3.72% as of last Friday, 63 basis points below year-ago levels, is partially a Fed funds story — and partially a story about a private stablecoin ecosystem that has become structurally wedded to rolling over short-dated American debt every 93 days.
The exposure lives in two places. First, in the short end of any fixed-income portfolio: if the stablecoin market stalls — Bitcoin fell more than 50% from its October 2025 peak of $126,000, and stablecoin growth has plateaued just above $300 billion since the GENIUS Act's passage — then one of the largest structural buyers of T-bills withdraws, and the front end reprices faster and harder than any Fed model anticipates. Second, in the dollar itself: the GENIUS Act was sold as a mechanism to "buttress dollar reserve status" by creating private demand for dollar-denominated instruments across the developing world. What it actually created is a $300 billion pool of dollar claims, held by users in 160 countries, backed by reserves that a private company in El Salvador controls and that no US regulator can seize on 24 hours' notice.
Standard Chartered projects $800 billion to $1 trillion in new T-bill demand from stablecoin growth through 2028 — but that projection assumes the market grows from $300 billion toward $2 trillion, and the growth has already stalled, Bitcoin has cratered, and the largest issuer operates outside the audit requirements that the law was written to impose, leaving $186 billion in circulating dollar claims backed by attestations from a firm in Italy and reserves managed through structures that the Treasury's own TIC reporting system cannot see.
Treasury Secretary Bessent called it a revolution in digital finance. The people who actually read the reserve attestations called it a $135 billion position in US government debt held by a company that is not required to open its books. Both things are true. Washington needed a buyer. They found one. They just can't audit it. And the man on television called it a landmark for American financial innovation.
