SKN | Stablecoin Growth Could Strengthen Dollar Dominance and Boost U.S. Treasury Demand

Key Takeaways

• Bank of England Financial Policy Committee member Carolyn Wilkins said expanding dollar-backed stablecoins could reinforce the U.S. dollar’s global role by making cross-border settlement easier.
• Major issuers Tether and Circle held nearly $150 billion in U.S. Treasuries at the end of 2025 and purchased roughly $33 billion during the year.
• The same reserve structure creates a potential liquidity risk, because large-scale stablecoin redemptions could force issuers to sell Treasury assets during periods of market stress.

Stablecoins are increasingly becoming a link between cryptocurrency markets and traditional dollar-based finance, with implications extending into foreign exchange, government debt and global payments. Carolyn Wilkins, a member of the Bank of England’s Financial Policy Committee, said the expansion of dollar-denominated stablecoins could strengthen dollar dominance while creating additional structural demand for U.S. Treasury securities.

Stablecoins Expand the Digital Dollar Footprint

The stablecoin market has grown beyond its original role as crypto trading infrastructure. Total stablecoin capitalization exceeded $300 billion during 2026, with roughly 98% of the market denominated in U.S. dollars. The sector reached approximately $311 billion in August, up 1.19% from July, marking its first monthly expansion in three months.

For users outside the United States, dollar stablecoins can provide access to dollar-linked value without requiring conventional U.S. banking relationships. Their 24-hour settlement capability also reduces some of the friction associated with correspondent banking, potentially increasing the use of dollars in cross-border commerce and digital financial markets.

Treasury Demand Creates a New Market Link

The reserve requirements behind major stablecoins connect digital-asset growth directly to the U.S. government bond market. Tether’s USDT and Circle’s USDC together held nearly $150 billion in U.S. Treasuries at the end of 2025 and purchased approximately $33 billion during that year.

That scale makes stablecoin issuers increasingly relevant participants in short-term Treasury markets. As stablecoin supply expands, issuers generally need additional high-quality liquid assets to support redemption requirements. This can create incremental demand for Treasury bills and strengthen the connection between crypto adoption and U.S. government financing.

The effect is not necessarily one-directional. If stablecoin redemptions accelerate, issuers may need to liquidate reserves, potentially adding selling pressure to Treasury markets precisely when broader financial conditions are already strained.

Crypto Markets Gain Dollar Liquidity but Face Concentration Risk

For crypto investors, the growing dominance of dollar stablecoins has two competing implications. Greater stablecoin liquidity can improve trading, collateral and settlement across digital-asset markets, while the concentration of the sector around the dollar reinforces the importance of U.S. monetary policy and Treasury yields.

Bitcoin was trading around $76,000 in mid-September after a volatile period driven by geopolitical developments, oil prices and expectations for Federal Reserve policy. As stablecoins become a larger component of crypto market liquidity, changes in dollar funding conditions could increasingly influence digital-asset positioning.

Strategic Outlook for Digital Dollar Infrastructure

Stablecoin growth is evolving into a monetary and financial-market issue rather than a purely crypto-sector development. The combination of more than $300 billion in circulating stablecoins, predominantly dollar-denominated reserves and substantial Treasury holdings creates both additional demand for U.S. assets and a potential channel for liquidity stress. For institutional investors, the next stage of the market will depend on whether regulation, reserve transparency and redemption mechanisms can keep pace with stablecoin expansion without transferring crypto-market volatility into traditional financial markets.
