Digital Dollar Growth Could Deepen the World’s Reliance on U.S. Currency

The GENIUS Act, signed into law in July 2025, established federal rules for dollar-backed payment stablecoins.

Circle announced a five-year partnership with Binance in September 2026 to expand distribution of USDC, including in emerging markets.

The global stablecoin market stood at approximately $302.9 billion on October 16, 2026, according to DefiLlama.

Tether’s USDT accounted for about $183.5 billion and Circle’s USDC for $72.8 billion. The figures measure outstanding tokens rather than payments for goods, services or cross-border transactions.

The legislation requires permitted payment stablecoins to be backed by eligible liquid assets, including dollars and short-term U.S. Treasury securities.

Treasury Secretary Scott Bessent has cited additional demand for government debt among the potential benefits of wider stablecoin adoption.

Europe is advancing digital-euro and wholesale settlement initiatives, while China is expanding yuan payment channels.

The Bank for International Settlements is also testing cross-border settlement using tokenised commercial bank deposits and central bank money.

Dollar-backed stablecoins could bring more international payments into U.S. currency while increasing demand for American financial assets, even as other economies develop their own digital settlement networks.

U.S. Stablecoin Rules Could Extend the Dollar’s Reach

The GENIUS Act restricts U.S. payment stablecoin issuance to approved bank subsidiaries, federally licensed nonbank companies and qualifying state-regulated issuers.

It requires reserves covering outstanding tokens, monthly disclosures and redemption at a fixed monetary value, with oversight divided between federal and state authorities.

Dollar stablecoins can circulate between digital wallets internationally without holders maintaining conventional U.S. bank accounts.

Converting them into local currency or redeeming them through financial institutions remains subject to issuer policies, intermediary access and national regulations.

Circle reported $14.8 trillion in USDC blockchain transfers during the second quarter of 2026, an increase of 151% from a year earlier.

Blockchain transfer volume cannot be equated with commercial payments. Circle has also developed payment connections with Nium, which supports payouts in more than 190 countries, and Japan’s JCB for cross-border treasury and merchant transactions.

Tether’s USDT is used across cryptocurrency exchanges and digital wallets, providing access to dollar-denominated assets outside the United States. Available transfer figures do not establish how much USDT is used for commercial payments.

Stablecoin reserves can increase demand for short-term U.S. Treasury securities as token issuance grows, depending on issuers’ holdings and where investors would otherwise place their funds. Additional demand does not eliminate federal borrowing costs.

Dollar demand also reflects its use in oil pricing and settlement, although the GENIUS Act contains no provisions governing energy trade.

Regulated private stablecoins give the dollar another route into international payments without requiring the Federal Reserve to issue a digital currency.

Europe and China Are Expanding Their Own Currency Networks

The European Central Bank plans to pilot the digital euro in the second half of 2027, with possible issuance in 2029 pending legislation.

Its Pontes initiative began providing infrastructure for settling tokenised financial transactions in central bank money in September 2026.

Private euro stablecoins operate under the European Union’s Markets in Crypto-Assets Regulation, which sets authorization and reserve requirements for issuers.

The proposed digital euro would be a central bank liability. Pontes addresses wholesale settlement, and the ECB’s Appia initiative is examining the development of tokenised financial markets.

The ECB has identified Europe’s reliance on payment providers based outside the region as a concern for financial autonomy.

A digital euro would provide a public payment option across the currency union, alongside private payment services.

China’s Cross-Border Interbank Payment System processed 6.89 million transactions worth 162.3 trillion yuan during the first nine months of 2026.

Offshore yuan markets allow investors and businesses to obtain, exchange and hold the currency outside mainland China.

The People’s Bank of China is developing international applications for the digital yuan. Governor Pan Gongsheng said on October 16 that China would seek greater foreign investment in yuan bonds and expand cross-border financial infrastructure.

BRICS governments have discussed alternatives to established international payment networks, but the group has not introduced a common currency or a unified settlement system.

Bilateral agreements to use national currencies in trade do not establish the extent of yuan settlement in global oil markets.

Wider international use of the euro and yuan will depend on currency convertibility, access to financial markets and demand for assets denominated in those currencies.

BIS Project Agorá Is Testing Cross-Border Payments Without Private Stablecoins

Project Agorá completed 30 payments worth approximately 800,000 Swiss francs during controlled testing in July 2026.

The Bank for International Settlements reported an average settlement time of about 80 seconds. The prototype is not operating as a commercial international payment network.

The tests involved 28 central banks and financial institutions, including the Bank of England, Bank of Japan, Swiss National Bank, JPMorgan Chase, Deutsche Bank and UBS.

Transactions covered six currencies: the U.S. dollar, euro, British pound, Swiss franc, Japanese yen and South Korean won.

Participants tested corporate payments, interbank transfers and simultaneous currency exchanges, including sterling-dollar and sterling-franc transactions.

Agorá brings tokenised commercial bank deposits and central bank reserves onto shared infrastructure.

Participating banks can transfer deposits and settle the corresponding obligations in central bank money, reducing the separate instructions and reconciliation required between institutions.

Customers continue to hold claims on their commercial banks rather than private stablecoin issuers. Participation is limited to regulated financial institutions, not consumers transferring money through digital wallets.

The Financial Stability Board wants 75% of wholesale cross-border payments to reach recipients within one hour by the end of 2027.

The G20 has set a target of reducing the average cost of sending $200 to 3% by 2030, against a World Bank reported average of 6.36%. Charges remain particularly high on remittance routes serving sub-Saharan Africa.

Faster settlement does not determine the final cost of a transfer. Banks must still account for foreign-exchange spreads, regulatory checks, liquidity requirements and access to local financial institutions.

Agorá’s controlled tests have not established how much those costs would change in commercial use.

Whether the system can reduce international payment costs will depend on its performance beyond controlled testing and the willingness of financial institutions to adopt it.

Digital Payment Networks May Change How Money Moves, Not Which Currency Leads

The U.S. dollar accounted for 56.70% of global foreign-exchange reserves in the second quarter of 2026, according to the International Monetary Fund. The euro held 20.60% and China’s renminbi 2.11%.

Swift’s September 2026 currency tracker recorded the dollar in 52.09% of payment value processed through its network during August.

The euro accounted for 21.37% and the yuan 3.26%. Swift’s figures exclude payments outside its network, and IMF reserve statistics measure central bank holdings rather than commercial transactions.

Greater international demand for the euro would require a larger supply of liquid, accessible euro-denominated assets.

China’s capital controls continue to restrict the movement of funds into and out of yuan assets, limiting their appeal to foreign investors and reserve managers.

Businesses in countries with limited correspondent banking access could benefit from cheaper international transfers as new payment networks develop.

Wider circulation of dollar stablecoins could also increase the use of U.S. currency in domestic transactions, weakening demand for local money and complicating monetary policy in economies facing currency depreciation.

Governments pursuing greater financial independence need payment infrastructure connected to international networks, dependable domestic banks and functioning currency markets.

Without confidence in domestic currencies, faster payment systems could make it easier for households and businesses to move their money into dollars.
