Crypto Regulation: MiCA, SEC, and the Global Patchwork

Commissioned, Curated and Published by Russ. Researched and written with AI.

What’s New This Week

The big development this week is the stablecoin yield ban. The bipartisan Tillis-Alsobrooks compromise text – the deal designed to unblock the Digital Asset Market Clarity Act after months of stalemate – was circulated to industry on March 24. It explicitly prohibits passive yield on stablecoin balances: no interest-like rewards for simply holding tokens. Activity-based rewards tied to transactions and loyalty programmes are still permitted, but the economic equivalence test is written broadly to close structuring workarounds. The market reacted immediately – Circle fell 19%, Coinbase fell 11% on the day. Senate Banking Committee markup is now targeted for late April.

Also today: the House Financial Services Committee held a dedicated tokenization hearing (‘Tokenization and the Future of Securities: Modernizing Our Capital Markets’), with the tokenized real-world asset market now above $26 billion. The hearing is read as a signal that legislative momentum is building ahead of the Senate markup.

Changelog

EU MiCA

MiCA (Markets in Crypto-Assets) is the most comprehensive crypto regulatory framework in existence. It covers exchanges, stablecoin issuers, and crypto asset service providers (CASPs) across all 27 EU member states under a single passportable licence.

The implementation timeline ran in phases. Stablecoin rules came into force in mid-2024. The CASP rules – covering exchanges and trading platforms – apply fully as of July 1, 2026, which is the final compliance deadline for most firms. Some jurisdictions expired their transitional periods earlier: the Netherlands required compliance by July 2025.

As of March 2026, 14 cryptocurrency exchanges have obtained full CASP authorisation under MiCA, according to reporting from Blocklr. The number is small because the full compliance window has not yet closed – more firms are expected to apply ahead of the July 1 deadline. Firms that are not authorised by then cannot legally operate in or market to EU customers.

The ESMA (European Securities and Markets Authority) public register lists all authorised CASPs. SwissBorg obtained MiCA authorisation in France, one of the stricter supervisory jurisdictions.

One complication: Poland’s president vetoed the Crypto-Assets Market Act twice, leaving a national implementation gap. MiCA is directly applicable EU law, but it still requires national infrastructure to enforce.

What MiCA covers: exchanges, wallet providers, token issuers, stablecoin issuers. What it does not cover (yet): DeFi protocols, DAOs, and truly decentralised systems with no identifiable legal entity. The DeFi carve-out is real but not permanent – the European Commission has committed to reviewing the position.

US: Commodity Classification and Stablecoin Legislation

The Trump administration entered office in 2025 with a pro-crypto posture. The executive actions: a Strategic Bitcoin Reserve created using seized BTC; a prohibition on a US CBDC; a presidential working group on digital assets.

The Bitcoin reserve has been symbolically significant but practically limited. The reserve uses seized Bitcoin rather than market purchases, and the legislative effort to codify and expand it into a formal reserve policy had not passed as of March 2026.

The March 17, 2026 SEC-CFTC joint guidance classified Bitcoin, Ethereum, Solana, and 13 others as digital commodities. This matters: commodity classification means CFTC oversight, which is historically lighter-touch than SEC securities regulation. The classification resolves a long-running ambiguity that made institutional deployment difficult.

The GENIUS Act is now law. President Trump signed the Guiding and Establishing National Innovation for US Stablecoins Act on July 18, 2025. It passed 68-30 in the Senate and 308-122 in the House – the first comprehensive federal legislation on digital assets enacted in the United States.

The law’s core provisions: only two categories of entities may issue payment stablecoins – subsidiaries of insured depository institutions, and nonbank entities licensed by the OCC. Issuers must back tokens one-to-one with high-quality liquid assets (US currency, T-bills), with monthly reserve composition disclosures required. In bankruptcy, stablecoin holders have priority claims against issuer reserves over other creditors.

The OCC published proposed implementing rules on March 2, 2026, covering licensing, reserves, and operational standards. The 60-day comment window is open. Regulators must finalise implementing rules by July 18, 2026, with the law taking effect January 18, 2027 (or 120 days after finalisation, whichever comes first).

The remaining live legislative question is the CLARITY Act, which covers market structure for digital assets more broadly. The CLARITY Act stablecoin yield compromise text was released on March 24, 2026. The Tillis-Alsobrooks deal bans passive yield on stablecoin balances – any reward that is economically or functionally equivalent to bank interest is prohibited, including indirect arrangements through affiliates. Activity-based rewards tied to transactions, subscriptions, and platform use remain permitted. The text is explicitly designed to close the loophole that banking groups argued would accelerate deposit flight. Industry reaction has been sharply negative. Coinbase fell 11% and Circle fell 19% on the day the text circulated. Senate Banking Committee markup is now targeted for the second half of April 2026.

The Guardian reported on March 22, 2026 that the new SEC interpretations on securities definitions could benefit Trump family crypto projects – a political complication that has attached to the narrative of regulatory reform.

UK: FCA Registration Regime

The UK FCA requires crypto businesses to register under the Money Laundering Regulations. This is not a full licensing regime in the MiCA sense – it is primarily an AML/KYC compliance gate. The FCA has been slow to approve registrations and has rejected or delayed a number of high-profile applicants.

The UK’s approach is less structured than MiCA. There is no passportable licence across jurisdictions, no clear stablecoin framework, and no comprehensive market abuse regime for crypto assets yet. The UK government has signalled intent to develop a fuller framework, but the pace has been slow compared to the EU.

The practical effect: compliant firms in the EU under MiCA cannot automatically operate in the UK. Post-Brexit, UK and EU regulatory regimes diverged, and crypto is no exception.

Asia: Singapore, Hong Kong, Japan, Dubai

Singapore (MAS): The Monetary Authority of Singapore operates a relatively permissive regime with clear licensing pathways. Major exchanges have MAS licences. The framework is considered business-friendly while maintaining AML standards.

Hong Kong: Launched a mandatory licensing regime for virtual asset trading platforms in 2023. Hong Kong has positioned itself as an institutional crypto hub, with clear rules for retail access and institutional trading. Several major exchanges have obtained Hong Kong licences.

Japan: The most mature regulatory framework globally. Japan has licensed exchanges since 2017, with strict requirements on custody, AML, and consumer protection. The framework is comprehensive and battle-tested – Japan has handled multiple exchange failures (Mt Gox being the most significant) through its regulatory structure.

Dubai (VARA): The Virtual Assets Regulatory Authority is a purpose-built crypto regulator. Binance, Bybit, and others have obtained VARA licences. Dubai’s approach is explicitly growth-oriented.

CBDCs – Where Is Digital Currency Actually Launching?

The CBDC landscape is more theoretical than live. Notable positions:

China’s digital yuan (e-CNY) has the most advanced deployment, with trials across multiple cities and integration into payment infrastructure. The scale of genuine adoption remains unclear from outside.

The US explicitly prohibited a retail CBDC under the Trump executive order. The US will not have a CBDC in the near term.

The European Central Bank is preparing a two-track approach. A digital euro for retail use remains in the design phase, with a decision on whether to proceed expected in 2025-2026. Alongside this, the Eurosystem is developing “Pontes,” announced on March 23, 2026, which will connect blockchain platforms with central bank money as a wholesale settlement infrastructure. ECB executive board member Piero Cipollone described the initiative at a Brussels event, noting that tokenized markets cannot scale without a trusted on-chain settlement anchor. Pontes is expected to launch in Q3 2026.

The UK is in the design phase. India has a pilot in progress. Most other major economies are researching rather than deploying.

The practical reality: CBDCs are government-designed digital currencies, not blockchain-based assets in any meaningful sense. They are programmable, potentially surveilled, and represent a fundamentally different model to decentralised crypto. The DeFi community treats them as a threat rather than a complement. Pontes is different in focus – it targets wholesale settlement infrastructure rather than consumer digital cash.

DeFi’s Regulatory Grey Zone

The central question: can you regulate code? If there is no company, no identifiable operator, no server to seize – what does enforcement look like?

The US government’s answer in 2023 was to sanction Tornado Cash’s smart contract addresses, making it illegal for US persons to interact with them. That action is being litigated. The argument for the prosecution: sanctions can apply to property, not just persons. The argument against: code is speech, and sanctioning a permissionless protocol penalises users rather than operators.

MiCA sidesteps this by focusing on identifiable service providers. Fully decentralised protocols with no EU legal entity are currently outside scope. This may not last.

The practical enforcement reality: regulators can target fiat on-ramps and off-ramps. Centralised exchanges face the full weight of regulation. DeFi protocols are harder but not untouchable – the US has pursued development teams under securities and money transmission laws.

Stablecoins as the Regulatory Battleground

Stablecoins are where regulatory and financial system risk overlap. USDT (Tether) and USDC (Circle) dominate – though the gap is narrowing. USDC supply grew by approximately $4.5 billion through March 2026 while USDT declined by roughly $2 billion, reflecting institutional preference for the GENIUS Act-compliant issuer, according to CoinGenius. Total stablecoin transaction volume hit $33 trillion in 2025.

The GENIUS Act creates a federal framework requiring 1:1 reserves and regular attestation. This is broadly modelled on MiCA’s stablecoin requirements.

The unresolved question is yield. Yield-bearing stablecoins from DeFi protocols are entering a market that is being regulated in real time. The CLARITY Act text released March 24 is the answer banking groups lobbied for – passive yield is now explicitly on the prohibited list. Whether that closes all the workarounds the text claims to close will take time and legal challenge to determine.

What This Means for Builders

Practical compliance considerations as of March 2026:

If you’re operating in the EU: full MiCA CASP compliance required by July 1, 2026. This means authorisation, reserve requirements, governance standards, and consumer disclosure.

If you’re operating in the US: the commodity classification clarifies BTC/ETH/SOL but does not resolve every token. If you’re issuing stablecoins, the GENIUS Act framework is now live – you need to determine which issuer category applies and whether you’re in the 18-month transition window. OCC rulemaking is in the comment period through approximately May 2026.

If you’re building DeFi: you are currently in a regulatory grey zone. Maintain the legal infrastructure (corporate entity, legal opinions, AML monitoring) to demonstrate good faith, and watch what jurisdictions do with the DeFi carve-outs in MiCA’s review cycle.

If you’re a builder in Asia: Singapore and Hong Kong offer clear pathways. Dubai is available for offshore structuring. Japan is the most mature if you need a consumer-facing regulated entity.

The patchwork is not going away. The trajectory is towards more coverage, not less – every major jurisdiction is building regulatory infrastructure. The question is which frameworks get built right.
