Dollar-pegged tokens represent 99.76% of the $300 billion stablecoin market. The GENIUS Act of July 2025 requires issuers to hold reserves in cash or Treasury bills maturing within 93 days. Standard Chartered forecasts the market will reach $2 trillion by 2028, generating up to $1 trillion in new demand for Treasury bills.
As of March 31, 2026, Tether held approximately $141 billion in US Treasuries, ranking as the 17th largest holder globally, ahead of Germany and the UAE. Along with Circle, these two private companies control about 88% of all stablecoins in circulation.
BIS research finds that a $3.5 billion stablecoin inflow lowers 3-month Treasury bill yields by 2 to 2.5 basis points, while outflows of the same size raise yields by 6 to 8 basis points. A stablecoin run now transmits directly into the market that determines the global risk-free rate.
ECB data identify Tether as the largest gold buyer of 2025, purchasing slightly more than the roughly 100 tonnes acquired by Poland, the top official buyer. The company that earns billions from digital dollars held about 132 tonnes of gold worth nearly $20 billion by March 2026.
The stablecoin market shrank by $7.7 billion in June 2026, marking the largest monthly decline since the Terra collapse in May 2022, according to RWA.xyz. Total circulation has dropped $10 billion since the end of May and is now near $300 billion. Each redeemed token requires issuers to return a dollar, and the 2025 framework ensures these dollars remain invested in Treasury bills.
In 2025, Washington established a legal framework that channels global demand for digital dollars into demand for US debt. This mechanism also operates in reverse, as seen in the current contraction, the deepest since the framework became law.
The GENIUS Act, signed on July 18, 2025, requires issuers to back every regulated stablecoin, a digital token built to hold a fixed $1 value, with cash, insured deposits, Treasury bills maturing within 93 days, or similar short-term instruments. Treasury Secretary Scott Bessent called the legislation “a once-in-a-generation opportunity to expand dollar dominance.” A January 2025 executive order had already barred a US central bank digital currency, so the strategy runs entirely through private balance sheets.
Dollar-pegged tokens represent 99.76% of all stablecoins in circulation, while tokens tied to the euro, yen, and every other currency combined total just $771 million, according to Artemis data from April 2026. The dollar’s share of official reserves has slipped to roughly 57% from 72% in 2001, yet on public blockchains its dominance keeps widening.
Bessent told the Senate in June 2025 that $2 trillion was “a very, very reasonable number” and said the figure could be greatly exceeded. Standard Chartered projects $2 trillion by the end of 2028, a size that would generate up to $1 trillion in additional demand for Treasury bills. Citi raised its 2030 forecast to $4 trillion in July 2026, even as actual circulation contracts.
Tether reported approximately $141 billion in direct and indirect US Treasury exposure as of March 31, 2026, in an attestation prepared by accounting firm BDO. That position makes one private company the 17th largest holder of US government debt in the world, ahead of Germany, the UAE, and South Korea. Circle’s USDC, with $73 billion outstanding, keeps most of its reserves in short-dated Treasuries and repurchase agreements, lifting the two firms’ combined exposure above $200 billion.
Market concentration is more significant than size. USDT and USDC together account for about 88% of all stablecoins, so the Treasury demand Washington relies on flows through just two redemption desks. Tether earned $1.04 billion in the first quarter of 2026, holds a record $8.23 billion in excess reserves, and began its first full audit under KPMG after a decade of quarterly attestations.
Overseas investors now hold about one-third of the more than $30 trillion in outstanding US Treasury securities, down from roughly half ten years ago. Stablecoin issuers have become the fastest-growing marginal buyers at the front end of the curve, a segment that was negligible when the market was valued at $20 billion in 2020.
BIS Working Paper 1270 quantified the link between stablecoin flows and government debt for the first time. A $3.5 billion inflow into stablecoins lowers 3-month Treasury bill yields by 2 to 2.5 basis points within ten days, while outflows of the same size push yields up by 6 to 8 basis points. The researchers compare the magnitude to that of small-scale quantitative easing and find that the impact doubles when bill supply becomes scarce.
This asymmetry arises because growth is gradual, while redemptions are forced. Issuers can purchase bills at their own pace during expansions, but a redemption wave requires immediate sales at prevailing market prices, with no deposit insurance, discount window, or redemption gates like those adopted by money market funds after 2008. When the Reserve Primary Fund broke the buck in September 2008, approximately $300 billion exited prime money funds within a week, and the run ended only after the US Treasury guaranteed the entire industry.
Recent stress scenarios are well documented. In March 2023, USDC traded near $0.87 after $3.3 billion of Circle’s reserves were frozen at Silicon Valley Bank, with the peg recovering only after federal regulators guaranteed the bank’s deposits. On October 10, 2025, a tariff announcement from Washington triggered $19 billion in crypto liquidations within 24 hours, eliminated 1.6 million trading accounts, and drove the synthetic dollar USDe to $0.65 on one major platform.
ECB data published in June 2026 identify Tether as the largest single gold buyer in 2025, with purchases slightly exceeding the approximately 100 tonnes acquired by Poland, the largest official-sector buyer. Central bank purchases declined to around 850 tonnes in 2025 from over 1,000 tonnes annually between 2022 and 2024, while the average gold price rose 43% to $3,431 per ounce. In the year the ECB reported gold surpassed US Treasuries as the largest official reserve asset, a private company outbought every central bank.
Jefferies calculated that Tether’s 26-tonne gold purchase in the third quarter of 2025 exceeded that of any individual central bank during the same period. By March 31, 2026, Tether held about 132 tonnes of physical gold worth nearly $20 billion, ranking among the top 30 sovereign-scale holders, above Australia, Qatar, and Greece.
Tether earns profits from dollar interest rates, holds $141 billion in US government debt, and allocates a growing share of proceeds to gold, an asset that pays no yield and is not subject to government control. The company presents its gold holdings as diversification and backing for its gold token, a rationale also used by central banks when reducing dollar concentration.
Scale changes the arithmetic the BIS measured. At a $2 trillion market, a redemption of just 5% in one week would force $100 billion of bill sales, nearly 30 times the flow size behind the 6 to 8 basis point estimate, and the impact doubles in exactly the conditions a crisis creates. The GENIUS Act gives holders priority claims in an insolvency, but priority sets the order of losses and creates no fresh liquidity during a run.
Three indicators are key for forex and rates traders through 2027. Weekly stablecoin supply now closely tracks front-end Treasury flows in real time, and the current contraction is the first sustained test since the law’s enactment. Debt ceiling standoffs double the yield impact of any redemption, and Tether’s quarterly attestations reveal whether the largest issuer continues shifting profits from Treasuries to gold.
The 1974 petrodollar arrangement linked dollar demand to oil and operated through governments. The 2025 framework ties dollar demand to code and operates through two private companies whose combined Treasury holdings already exceed Germany’s. Both systems create structural demand for US debt and concentrate run risk that becomes apparent only under stress.
A bank run once ended at a teller window with a queue outside. Today, a stablecoin run concludes at a Treasury auction screen and settles at blockchain speed. BIS data already indicate which direction has greater impact. The $20 billion in gold on the largest issuer’s balance sheet suggests the system’s operators recognize this asymmetry.
