As foreign official holdings retreat, crypto firms are identified by the San Francisco Fed as an increasingly meaningful source of demand for United States debt.
As foreign official holdings lose ground, new demand for United States government debt is being generated by emerging stablecoin issuers.
Over the past five years, approximately $200 billion in Treasury securities and repurchase agreements have been added by Tether and Circle, matching over 40% of China’s reduction in Treasury holdings during that timeframe, according to researchers at the Federal Reserve Bank of San Francisco.
An alteration of the investor base supporting the world’s largest government bond market is being initiated by this transition, while China has sustained a retreat from American sovereign debt that started over ten years ago, and stablecoin issuers’ holdings of Treasuries have expanded tenfold over a five-year span alongside growing demand for digital dollar tokens.
Stablecoins Expand as Foreign Governments Pull Back
As the composition of American creditors undergoes a long-term transformation that could be influenced by the growth of crypto-linked purchasers, the cost for Washington to finance its deficits may ultimately be impacted.
By early 2026, foreign investors’ share of outstanding Treasury securities had been reduced to approximately 30% from over half in 2008, according to the San Francisco Fed, while foreign governments within that category experienced an even steeper decline in relative significance, representing just over 40% of overseas demand by early 2026 after accounting for nearly the entire share at their peak during the 1970s.
Central to that shift has been China, whose Treasury holdings peaked in late 2013 and were reduced by more than half by mid-2026 as Beijing diversified its reserve assets.
A larger role has been assumed by private investors as official foreign demand weakened, potentially rendering Treasury financing more sensitive to interest-rate changes and perceptions of American fiscal risk, whereas unlike central banks—which might hold Treasuries for reserve management—private actors can demand higher yields when risks rise or alternative returns grow.
A distinct source of demand is provided by stablecoin issuers because their business model requires vast pools of liquid dollar assets to back tokens that can be redeemed at par by customers.
More than 80% of stablecoin market capitalization was accounted for by Tether’s USDT and Circle’s USDC as of mid-August, according to Fed researchers, while both issuers hold substantial quantities of short-term Treasury securities alongside cash, bank deposits, and repurchase agreements to satisfy redemption demands.
Significant participants at the short end of the Treasury market have been established by their growth, with stablecoin issuers having added more short-term Treasury holdings since 2023 than Japan—the largest foreign holder of American government debt—according to the research.
An impact on short-term government bond yields large enough to be measured is indicated by that demand, according to the San Francisco Fed, referencing findings from the Bank for International Settlements.
The China Comparison Comes With a Maturity Gap
The specific variety of demand withdrawn by China cannot be entirely replaced by stablecoins, as both investor groups operate within distinct segments of the Treasury market.
Largely concentrated in longer-dated American debt have been China’s reductions, whereas Treasury bills and other highly liquid, short-maturity assets are predominantly purchased by stablecoin issuers, meaning that expanding stablecoin reserves can deepen demand for bills without necessarily creating an equivalent buyer for longer-term notes and bonds.
Heavier financing requirements are currently faced by the United States as this distinction emerges, with publicly held federal debt climbing from approximately 35% of gross domestic product in 2006 to roughly 100% today, thereby intensifying scrutiny over the investor base prepared to absorb new issuance.
A preference for the shortest maturities among stablecoins could be reinforced by regulation.
A federal framework requiring approved United States payment stablecoin issuers to fully back outstanding tokens with eligible liquid reserves was established in 2025 by the GENIUS Act.
Cash, bank deposits, and select Treasury-backed repurchase agreements, alongside Treasury bills, notes, and bonds with remaining maturities of 93 days or less, are encompassed by proposed implementing rules.
An effective link between growth in regulated dollar stablecoins and incremental demand for highly liquid United States government securities is created by that structure.
Attractive economics are also offered to issuers, because customers hold tokens that typically do not pay them the yield earned on reserve assets, while operators can collect interest from the Treasury securities backing those digital coins.
Reserve portfolios and the associated interest income are enabled to climb alongside the expansion of circulation.
Global Stablecoin Growth Could Drive More Capital Into T-Bills
The next phase will be determined by whether stablecoins continue attracting users outside the traditional cryptocurrency trading market.
Particularly high usage relative to economic output is observed in Africa, the Middle East, and Latin America, where much of the activity crosses national borders, as the San Francisco Fed highlighted the expanding employment of stablecoins for cross-border payments and as dollar-denominated stores of value within nations experiencing volatile currencies.
An indirect channel enabling a foreign stablecoin user to finance United States government borrowing is thus forged, whereby an acquiring customer generates supplementary reserve liabilities for the issuer, which can consequently purchase Treasury bills to back them.
Those holdings would be propelled toward $400 billion by 2030 if the sector’s recent expansion pace is prolonged, although Fed researchers cautioned that substantial uncertainty accompanies the projection, and international regulations, rival digital-payment options, or emerging banking technology could each decelerate stablecoin adoption.
The volume of the upcoming wave of dollar-based payments that will ultimately be funneled through stablecoin issuers and into Treasury markets is dictated by those competitive pressures.
Some of that demand might be captured by traditional banking institutions designing cheaper cross-border settlement tools, whereas expanding stablecoin firms venturing into remittances and payments must continually enlarge their liquid reserves as circulation grows.
