Stablecoins Outpace Visa and Mastercard as Regulations Lag Behind

Stablecoins now settle more daily transaction volume than Visa and Mastercard combined, yet the legal frameworks governing their issuance, reserves, and redemption remain fragmented across jurisdictions. This gap between operational scale and regulatory clarity has become one of the defining structural tensions in digital asset markets, and the frameworks now taking shape in the United States, European Union, and Asia will determine whether stablecoins evolve into a pillar of global financial infrastructure or remain a contested instrument at the edge of the regulated system.

The Global Regulatory Patchwork Taking Shape

Three distinct regulatory philosophies have emerged across major financial jurisdictions, each reflecting different priorities around consumer protection, monetary sovereignty, and innovation policy.

The European Union moved earliest among large economies with its Markets in Crypto-Assets regulation, known as MiCA, which entered full force in 2024. MiCA establishes a licensing framework for stablecoin issuers, distinguishing between e-money tokens pegged to a single fiat currency and asset-referenced tokens backed by a broader basket. Issuers of e-money tokens must hold a full 1:1 reserve, publish regular audits, and obtain authorisation from a member state regulator. MiCA also imposes transaction volume caps on non-euro stablecoins, a provision that drew considerable attention from issuers of dollar-denominated tokens like Tether's USDT and Circle's USDC, as high daily settlement volumes in euro markets could trigger regulatory constraints.

In the United States, Congress has worked through competing legislative frameworks. The core debate centres on which agencies have primacy over stablecoin issuers - the Federal Reserve, the Office of the Comptroller of the Currency, or state-level banking regulators - and whether non-bank entities can issue payment stablecoins at all. The general direction of proposed legislation favours reserve requirements backed by short-duration Treasury bills or cash equivalents, monthly attestations, and mandatory redemption rights at par. This mirrors the reserve model that Circle already applies to USDC, which maintains backing through cash and short-duration U.S. Treasury bills.

Asia presents a more varied picture. Singapore's Monetary Authority finalised its stablecoin framework in 2023, requiring single-currency stablecoins pegged to the Singapore dollar or G10 currencies to maintain a reserve value at or above the par value in circulation. Hong Kong has moved to license stablecoin issuers under its banking law amendments, signalling intent to position the city as a regulated hub for tokenised financial instruments. Japan, which recognised cryptocurrency exchanges as regulated entities as early as 2017, subsequently restricted stablecoin issuance to licensed banks, trust companies, and fund transfer operators - one of the stricter frameworks globally.

Why TradFi Institutions Are Watching Closely

The convergence of traditional finance and stablecoin infrastructure is accelerating precisely because the underlying technology solves a real problem: cross-border settlement. Correspondent banking networks can take two to five business days to complete an international wire transfer and extract fees at multiple points. A dollar-denominated stablecoin on a programmable blockchain can settle a transaction in seconds for a fraction of a cent, with full transparency of the transaction record.

This is why global custody banks, payment networks, and asset managers have moved from observation to active participation. Tokenised money market funds - products that combine stablecoin-like programmability with regulated fund structures - have attracted significant institutional interest as a vehicle for placing short-term liquidity on-chain without exposure to unregulated issuers. The Fear and Greed Index currently reads 33, reflecting cautious sentiment across broader crypto markets, but institutional engagement with stablecoin infrastructure has followed a different logic than retail price sentiment - it is driven by treasury efficiency and settlement cost reduction, not by speculative cycles.

The Kraken parent company's recent expansion of tokenised stock products into Hong Kong, the UK, and South Korea illustrates how regulated intermediaries are building layered financial products that combine the settlement properties of blockchain rails with compliant access to traditional asset classes. This convergence is precisely what regulators are attempting to govern: not stablecoins in isolation, but the emerging hybrid infrastructure where programmable money interacts with regulated securities. For broader context on how tokenisation applies across asset classes, the concept of smart contracts is foundational to understanding how programmable settlement actually functions.

The Reserve Question and Systemic Risk

Regulators across all jurisdictions share one consistent concern: reserve quality and transparency. The catastrophic failure of TerraUSD in May 2022, which destroyed approximately $40 billion in value within 72 hours, demonstrated that algorithmic stablecoin models without genuine asset backing can collapse in a self-reinforcing spiral. Post-Terra, the global regulatory consensus has moved firmly toward requiring full, high-quality liquid asset backing - the algorithmic model is effectively off the table in any jurisdiction with a serious regulatory framework.

What remains contested is the acceptable composition of reserves. Proposals that allow issuers to hold longer-duration securities introduce mark-to-market risk: if reserve assets decline in value before a redemption wave, an issuer could face an insolvency gap. The most conservative frameworks, including Singapore's and the direction of U.S. federal proposals, require overnight-eligible assets or cash equivalents only. This effectively means stablecoin issuers at scale become significant buyers of short-duration government securities - a structural dynamic that gives central banks and treasury departments a direct economic interest in how the sector develops.

What to Watch as Frameworks Mature

Several inflection points will define the next phase of stablecoin regulation. U.S. federal legislation, if enacted, would create a single national framework that supersedes the current state-by-state patchwork and could unlock broader institutional adoption of payment stablecoins by banks. Interoperability between jurisdictions - whether MiCA-compliant issuers can operate freely in Asian markets and vice versa - will determine whether the stablecoin market fragments into regional silos or achieves the global settlement layer that its proponents envision.

Audit and attestation standards are also under active development. Real-time proof-of-reserve mechanisms using on-chain verification are being explored as a supplement to periodic third-party attestations, though no major jurisdiction has yet mandated them. The trajectory of regulatory development suggests that stablecoins compliant with reserve, redemption, and disclosure requirements will become a legitimate instrument within the global payments architecture - while non-compliant issuers face progressive exclusion from regulated financial rails. Institutions building positions in this space are not betting on a speculative price cycle; they are betting on stablecoins becoming the settlement layer for a digitised global financial system.
