Stablecoins are no longer confined to crypto exchanges: they are becoming a contested piece of payment infrastructure, forcing regulators to decide how private digital dollars should connect with banks, markets and the wider financial system.
As of June 2025, stablecoins had a combined supply of roughly $250 billion, according to DefiLlama, while Artemis counted about $2 trillion in monthly transfer volume, but most of that activity reflected exchange settlement, trading and DeFi rather than commerce. Payments and remittances remained a smaller but growing use case: Visa’s June 2025 analysis estimated adjusted, non-bot stablecoin volume at about $200 billion a month, with only a fraction tied to genuine consumer or business payments. Their growth has drawn banks, payment companies, asset managers and technology firms into a regulatory debate that extends well beyond digital assets.
The central question is not simply whether stablecoins should be permitted. It is who should be allowed to issue them, what assets should back them, how quickly holders can redeem them, and which authorities should supervise the institutions responsible for those promises.
Those decisions will determine where liquidity accumulates. If regulated banks and payment companies can issue or distribute stablecoins under clear standards, tokenized dollars could move into merchant payments, treasury management and international settlements. If rules impose heavy capital, licensing or reserve requirements, activity may remain concentrated among a smaller group of specialized issuers. Either outcome would reshape the flow of money through crypto markets.
Reserves are the foundation of trust
A stablecoin attempts to maintain a fixed value, usually against the U.S. dollar. That stability depends on the issuer’s ability to honor redemptions when users want to leave the system. The quality and liquidity of the reserve assets therefore matter more than the token’s branding or blockchain infrastructure.
The safest reserve model, from a financial stability perspective, generally relies on cash, central-bank balances or short-term government securities. These assets can be sold or transferred with relatively limited price risk. More complex arrangements may include commercial paper, corporate debt, loans or other instruments whose value can fall precisely when users become concerned about an issuer’s solvency.
That creates a familiar financial dynamic. A stablecoin may appear to function like money during normal conditions, but its reserves can face stress when confidence weakens. If holders seek redemptions simultaneously, the issuer may need to sell assets quickly. Forced sales could transmit pressure into money markets, particularly if reserves are invested in short-dated government securities or other highly traded instruments.
The Federal Reserve’s 2022 report, “Money and Payments: The U.S. Dollar in the Age of Digital Transformation,” directly addresses stablecoins, noting that faster payments could bring benefits but require clear legal claims, robust reserves and oversight to limit runs and settlement risks. Speed does not remove the need for finality, liquidity and clear responsibility when transactions fail.
For investors, reserve transparency is therefore a form of liquidity analysis. The important question is not only how many tokens are outstanding, but also what assets stand behind them, where those assets are held, how frequently they are disclosed and whether redemptions can be processed under stress.
The banking system is both competitor and gateway
Banks have several reasons to approach stablecoins cautiously. A widely used token could move deposits away from commercial bank accounts, reducing a source of low-cost funding for lending. During periods of uncertainty, customers might transfer balances from banks into tokens perceived as safer or more liquid, accelerating deposit outflows.
At the same time, banks possess advantages that new issuers may find difficult to replicate. They already operate within prudential frameworks, maintain payment connections and serve corporate treasuries that require compliance, credit and custody services. Their involvement could make stablecoins more acceptable to institutions that are unwilling to rely on lightly regulated intermediaries.
This tension explains why stablecoin policy is likely to focus on access and supervision as much as on technology. Regulators must decide whether issuers should be banks, specialized payment institutions, licensed technology companies or some combination of these models. They must also determine whether different types of stablecoins should face different requirements based on their use, scale and reserve structure.
A framework that allows many issuers to compete could promote innovation, but fragmentation may make it harder for users to assess risk. A highly concentrated market could simplify supervision while creating dependence on a small number of providers. The structure of the market will influence not just competition, but also the distribution of settlement liquidity across banks, exchanges and payment networks.
Global rules remain uneven
Stablecoins operate across borders even when their issuers are based in one jurisdiction. A token can be created in one country, held by users in another and traded through an exchange or protocol operating across several legal systems. That makes national regulation necessary but insufficient.
The Bank for International Settlements has repeatedly emphasized that fintech developments must be assessed through the functions they perform and the risks they create, rather than through technology alone. A token used for payments, savings, collateral or foreign-exchange settlement may create different supervisory concerns even if the underlying blockchain is identical.
The International Monetary Fund has also highlighted the monetary and financial implications of digital money. Stablecoins can improve access to payment services and reduce friction in international transfers, but widespread use could complicate capital controls, weaken domestic currency systems or increase exposure to foreign-currency risk. In emerging markets, a dollar-linked token may be attractive precisely because users distrust local monetary institutions. That demand can improve access to dollars while also increasing dollarization pressure.
This is why global coordination matters. Rules covering reserve quality, redemption rights, disclosure, anti-money-laundering controls and operational resilience will be more effective if they are broadly compatible. Otherwise, issuers may shift operations toward jurisdictions with weaker requirements, while users and institutions continue accessing the same tokens internationally.
The regulatory challenge is not to eliminate every difference between national systems. It is to prevent the most important protections from becoming optional when funds cross borders.
Payments adoption will test the model
Stablecoins have proven their usefulness in crypto trading because they allow users to move dollar exposure between exchanges and blockchains without relying on traditional banking hours or settlement processes. Payments adoption is a more demanding test.
Merchants need predictable conversion into local currency, protection against fraud, accounting standards and reliable customer support. Businesses also need to know who bears responsibility when a transaction is sent to the wrong address, when a wallet is compromised or when an issuer freezes funds under a legal order.
These requirements favor regulated intermediaries. A retailer may not want to manage private keys or monitor blockchain transactions, but it may adopt stablecoin payments if a bank, payment processor or fintech company hides that complexity behind familiar interfaces. In that model, the blockchain becomes the settlement layer while the customer experiences a conventional payment product.
Cross-border transfers could offer an earlier opportunity. Stablecoins can reduce the number of correspondent banks involved in a transaction and operate continuously across time zones. For companies with international suppliers, that may reduce settlement delays and working-capital requirements. For households sending remittances, lower fees could make the technology useful even without direct exposure to crypto markets.
However, efficiency depends on the full transaction chain. On-chain settlement does not by itself solve foreign-exchange conversion, compliance checks, local cash access or consumer disputes. The capital saved in one part of the system may be offset by costs elsewhere unless regulated payment networks develop around the tokens.
The market signal is supply, not headlines
The most informative indicators of stablecoin adoption are connected to money flows. Rising outstanding supply can show that users are bringing more dollar liquidity into crypto markets, but it does not automatically prove payments growth. Tokens may be issued because traders want collateral, because decentralized finance protocols require liquidity, or because institutions are testing settlement rails.
More useful analysis separates several channels. Exchange balances can indicate whether stablecoins are being held as trading liquidity. DeFi usage can show demand for programmable collateral. Transfer activity among corporate or institutional wallets may point toward settlement use. Redemption patterns can reveal whether holders treat a token as transactional money or as a temporary position during market stress.
The composition of reserves is another leading indicator. If issuers place more assets with regulated custodians and disclose holdings more frequently, institutions may become more willing to use stablecoins. If growth depends on opaque reserves or aggressive yield strategies, supply expansion could represent leverage rather than durable adoption.
Investor conviction will be visible in the willingness to hold stablecoins outside speculative venues. A token used for payroll, supplier payments, remittances or treasury operations has a different economic foundation from one that circulates mainly between exchanges. Regulation can accelerate that transition, but only if it makes the underlying promises credible.
A financial infrastructure decision
Stablecoins are moving closer to the mainstream because they solve a real problem: transferring dollar value across digital networks without waiting for traditional settlement systems. Their next phase will depend less on technical novelty than on institutional trust.
Clear rules could bring more capital into the sector by reducing legal uncertainty and allowing banks, payment companies and merchants to build around stablecoin rails. Strict requirements could also be constructive if they prevent issuers from treating redemption promises as a substitute for adequate liquidity management.
The risk is that policymakers focus on token issuance while overlooking the broader network of wallets, exchanges, custodians, banks and payment processors through which stablecoins move. Supervision must follow the money. A resilient framework will need to address reserves, redemption, custody, cybersecurity, consumer protection and cross-border enforcement together.
Stablecoins may eventually become a standard layer for digital payments, but that outcome is not guaranteed. Their future will be determined by whether regulators can preserve the speed and reach of tokenized dollars without importing the fragility of an unregulated shadow banking system. The flow of capital into stablecoins is already signaling demand. The rules will decide whether that demand becomes durable financial infrastructure.
