Why Currency Diversity will Define the Next Era of Stablecoins
Stablecoins have made a clear move from the edges of the financial system into the heart of its infrastructure.
In 2025, global stablecoin transaction volume reached $33 trillion, surpassing the combined annual transaction volume of Visa and Mastercard, with USDC alone processing $18.3 trillion. For cross-border payments, treasury management and settlement, digital dollars have proved their utility.
But the global financial system does not run on dollars alone. As stablecoins move deeper into enterprise payments use cases, the limits of a dollar-centric model are becoming more visible.
The next phase of stablecoin development will require an ecosystem that mirrors the actual structure of global commerce: multi-currency, interoperable and embedded in local financial systems.

Understanding the digital dollar’s dominance and its limits
USD-pegged stablecoins currently account for 99% of all stablecoin value in circulation, with USDC and USDT together commanding over 80% of the market capitalisation. Their dominance reflects the US dollar’s established role in international trade and finance: it remains on one side of 89% of all global FX trades.
That dominance is not without logic. Dollar-denominated stablecoins are widely accepted across exchanges and payment networks, and dollar settlement removes much of the FX uncertainty inherent in cross-border transactions. For businesses that invoice and contract in USD, digital dollars are a natural fit.
The challenge arises when payment flows must ultimately settle in another currency. A Brazilian business using stablecoins to pay a supplier in Japan currently converts through US dollars twice, incurring FX costs and settlement delays at each step.
For high-volume corridors denominated in euros, yen or regional currencies, routing everything through a digital dollar creates unnecessary friction and, in some markets, regulatory complications too.
Global commerce demands more than one digital currency
Non-USD currencies account for over 40% of daily global FX trading, across a market that hit $9.6 trillion in daily turnover in April 2025. Yet on-chain, those same currencies represent less than 1% of stablecoin activity. The euro, which underpins the world’s second-largest economy, is backed by stablecoins totalling just $500 million.
For companies managing international operations, this gap creates real cost.
Treasury teams holding digital dollar balances incur FX conversion fees every time funds must be converted to a non-dollar currency to reach a counterparty.
Settlement risk, FX volatility and working capital inefficiency all accumulate in the conversion steps that a genuinely multi-currency stablecoin ecosystem could eliminate.
Of the $6 to $ 7 trillion in daily global FX transactions; a third are subject to settlement risk, with counterparties either pre-funding positions or absorbing currency fluctuations. Stablecoins that settle in the actual transaction currency, rather than routing through an intermediary digital dollar, remove that risk at source.
Regulation is opening the door to currency diversity
The conditions for a multi-currency stablecoin ecosystem are beginning to take shape, driven primarily by regulatory change.
Europe’s Markets in Crypto-Assets (MiCA) regulation became fully applicable in December 2024, establishing for the first time a clear licensing and reserve framework for stablecoin issuers operating across the EU.
The immediate effect was to force the delisting of non-compliant tokens from European exchanges, creating space for regulated euro-denominated alternatives.
A consortium of nine major European banks announced plans in late 2025 to launch a MiCA-compliant euro stablecoin, with Circle’s EURC already operating on multiple blockchain networks as a regulated alternative. In Japan, regulators approved the first licensed yen stablecoin in 2025, and a further 12 European banks announced similar euro issuance plans targeting late 2026.
These are early signals of a structural shift, where tighter regulatory guidance is expected to drive consolidation around compliant issuers rather than suppress stablecoin adoption overall.
Why stablecoins could reshape how FX markets operate
The implications of a multi-currency stablecoin ecosystem extend beyond payments. As digital currency pairs become more liquid and widely adopted, FX markets themselves are likely to evolve alongside them.
Traditional FX settlement operates within fixed windows and carries meaningful settlement risk. Of the $6 to 7 trillion in daily global FX transactions, a third are subject to settlement risk, with counterparties either pre-funding positions or absorbing currency fluctuation between execution and settlement. Stablecoins, settling in seconds at any hour, remove that exposure at source
Treasury teams could hold balances across multiple currency-denominated stablecoins and convert between them instantly based on liquidity needs, shortening FX settlement cycles and unlocking working capital currently tied up in pre-funding requirements.
The long-term result may be an FX environment that operates continuously alongside global payment networks, less dependent on market hours, correspondent relationships and the delays inherent in conventional settlement infrastructure.
How to define an interoperable multi-currency stablecoin ecosystem
A multi-currency stablecoin ecosystem will only deliver on its promise if the currencies within it can move between each other and between digital and fiat rails without friction.
Issuing a euro-stablecoin addresses part of the problem. Making it interoperable with dollar stablecoins, local payment systems and fiat off-ramps is what determines whether it can function as a primary payment infrastructure.
Blockchain infrastructure already supports on-chain exchange between digital assets through decentralised liquidity pools, creating the conditions for 24/7 currency exchange embedded directly into payment flows.
But on-chain interoperability alone is not enough. Payments must ultimately connect to the local banking rails, mobile wallets and payout systems that businesses and individuals actually use.
Infrastructure that connects digital and local
For stablecoins to reach their potential in a multi-currency ecosystem, the infrastructure supporting them must reliably and compliantly bridge digital asset networks and local payment systems.
Businesses operating internationally need seamless pathways between stablecoins, fiat currencies and the wallets, bank accounts and real-time payment rails that serve their end markets.
This is where Thunes’ Direct Global Network, plays a critical role. By connecting stablecoin liquidity to over 12 billion mobile wallets and bank accounts, 15 billion cards and more than 320 payment methods across 140 countries, our Network ensures that digital assets can reach local endpoints without friction.
As the stablecoin ecosystem diversifies beyond the dollar, this kind of infrastructure becomes the connective layer that makes multi-currency stablecoin payments operationally viable.
The multi-currency future is already forming
Stablecoins have demonstrated that digital currencies can dramatically improve the speed, transparency and cost of cross-border payments. But realising that potential across global commerce will require more than one digital dollar.
Regulatory frameworks are beginning to enable a broader field of compliant stablecoin issuers. Institutional appetite for non-dollar alternatives is growing, particularly in Europe and Asia. And the blockchain infrastructure to support on-chain, multi-currency exchange already exists.
What remains is building the last-mile connectivity that brings stablecoin liquidity into contact with local payment systems at scale.
The stablecoin ecosystem that emerges will likely mirror the structure of the global economy itself: diverse in currency, interoperable by design and deeply connected to the local payment infrastructure that moves money where it actually needs to go.
