The Markets in Crypto-Assets Regulation (MiCA) took effect across the EU in 2024, bringing the first comprehensive crypto rulebook to the continent. Now exchanges and stablecoin issuers are pushing back. They argue that core definitions and capital requirements make their businesses unworkable.
Their lobbying centers on two pressure points: how perpetual futures (perps) are classified, and what reserves stablecoin issuers must hold. These aren't abstract policy debates. They will determine which products can operate in the EU, how much compliance costs, and whether builders route around European markets entirely.
How platforms are trying to reclassify perps as traditional derivatives
Hyperliquid and other perps-focused platforms argue that perpetual futures contracts should fall under the existing Markets in Financial Instruments Directive II (MiFID II) framework rather than MiCA. MiCA treats perps as crypto-assets, subjecting platforms to new licensing, capital, and custody rules. MiFID II, written for traditional derivatives exchanges, has lighter operational burdens for products traded on regulated venues.
The distinction hinges on whether a perp is fundamentally a crypto-asset or a financial instrument. Perps track the price of an underlying crypto asset but never deliver it—settlement happens in cash or stablecoin. Platforms claim this makes them more like cash-settled futures on oil or stock indices, which live under MiFID II. Regulators counter that because perps reference crypto prices and often use crypto as collateral, they belong in MiCA's scope.
Think of it like zoning law. MiFID II is the commercial district with established building codes. MiCA is the new tech district with stricter requirements. Platforms are arguing their building belongs in the old district because it uses familiar plumbing, even though it serves a new kind of customer.
If the reclassification succeeds, platforms could use existing MiFID II licenses instead of applying for new MiCA authorization. They would also escape MiCA's proof-of-reserves requirements and its caps on leverage for retail users. For a high-volume derivatives platform, this could mean lower compliance costs and faster time to market. For regulators, it risks fragmenting oversight—crypto products spread across two frameworks with different consumer protections.
The line between a crypto-asset and a traditional financial instrument isn't technical—it's political, and platforms are betting they can redraw it.
Circle's challenge to stablecoin reserve rules
Circle, issuer of USDC, has lobbied against MiCA's reserve composition rules for e-money tokens (EMTs)—the regulatory category covering stablecoins pegged to fiat currencies. MiCA requires EMT issuers to hold reserves in a "sufficiently diversified portfolio of high-quality liquid assets." It also limits holdings of a single asset to 25% of the reserve and caps claims on any one credit institution at 15%.
Circle argues these limits force issuers to spread reserves across multiple banks and asset types, increasing operational complexity and counterparty risk. USDC's reserves currently sit largely in short-term U.S. Treasury bills and cash at regulated banks. Circle claims this structure is safer than a diversified portfolio that includes corporate bonds or multiple banking relationships, each of which introduces new points of failure.
The European Central Bank (ECB) and national regulators see it differently. They argue that concentration in a single asset class—even Treasuries—creates systemic risk if that market freezes. A stablecoin with billions in circulation needs redundancy. If one bank fails or one asset class becomes illiquid, the issuer should still meet redemptions. MiCA's diversification mandate is meant to prevent a Terra-style collapse from spreading to retail holders across the EU.
Think of reserves like a backup generator system. Circle wants one large, reliable generator. MiCA wants three smaller generators from different manufacturers. Both approaches protect against outages, but they fail differently—and regulators worry about the scenario where the single generator's fuel supply gets cut.
The stakes are measurable. If Circle cannot meet MiCA's reserve rules without restructuring, USDC might lose its license to operate as an EMT in the EU. That would fragment liquidity. Traders would shift to offshore stablecoins or onshore alternatives that comply. For builders integrating stablecoins into payments or DeFi protocols, the reserve question determines which assets are safe to hold and whether they need fallback options for EU users.
The timeline and stakes of MiCA's review window
MiCA includes a built-in review process. The European Securities and Markets Authority (ESMA) must deliver its first assessment of MiCA's effectiveness by December 2026. This review will evaluate whether the framework achieves its goals—investor protection, market integrity, financial stability—and whether adjustments are needed. Lobby groups know this: the next 18 months are the window to shape that assessment.
Platforms are submitting position papers, meeting with ESMA staff, and funding research arguing that certain MiCA provisions are unworkable. They point to compliance costs, capital requirements that exceed those for traditional finance, and product restrictions that push activity offshore. The goal is to get specific amendments into ESMA's recommendations before they reach the European Commission and Parliament for legislative revision.
The stakes are layered. If ESMA's review leads to loosening MiCA's rules, platforms gain breathing room and the EU becomes more competitive with jurisdictions like Dubai or Singapore. If ESMA recommends tightening—perhaps citing gaps in enforcement or loopholes exploited by offshore actors—compliance gets harder and some firms exit. For builders, this timeline matters because any changes to MiCA will ripple into licensing requirements, product design, and which markets are worth targeting.
Platforms also face a parallel deadline: the transitional period for existing firms to apply for MiCA licenses ends in mid-2026. Firms operating under national regimes must either achieve full MiCA compliance or wind down EU operations. That compression—lobbying for rule changes while also preparing applications under current rules—creates a hedging problem. Build for the rules as written, or bet on the rules changing?
Why regulatory arbitrage between MiFID II and MiCA matters
The boundary between MiFID II and MiCA isn't just taxonomic—it determines which rulebook applies, and those rulebooks have different philosophies. MiFID II governs traditional financial instruments. It assumes regulated intermediaries, centralized order books, and products with decades of case law. MiCA was written for decentralized systems, token economics, and on-chain settlement. Where a product sits determines its compliance surface.
Consider a platform offering tokenized stocks, crypto perps, and spot trading. Under MiCA, all three might fall under one license. Under MiFID II, tokenized stocks are financial instruments requiring a different authorization. If perps move to MiFID II, the platform now needs two licenses, two compliance teams, and two reporting frameworks. This bifurcation raises fixed costs, especially for smaller platforms that can't spread overhead across high volumes.
Regulatory arbitrage also shapes product design. If MiCA's leverage caps make retail perps unprofitable, platforms might redesign products to fit MiFID II definitions—perhaps offering futures with expiries instead of perpetuals, or structured notes that reference crypto prices. Each workaround introduces friction: new contracts, new user experience, new liquidity fragmentation. Builders designing multi-jurisdiction platforms have to map these fault lines and decide which compromises to make.
| Framework | Scope | Capital requirements | Leverage limits | Custody model |
|---|---|---|---|---|
| MiCA | Crypto-assets, stablecoins, utility tokens | Higher; scaled to assets under custody | 2:1 retail, higher for pros | Mandatory segregation, proof-of-reserves |
| MiFID II | Traditional financial instruments | Lower; scaled to transaction volume | Set per product, flexible | Not always required for derivatives |
The table shows the trade-offs. Platforms lobbying for MiFID II treatment are betting that lower capital requirements and product flexibility outweigh the complexity of dual licensing. Regulators worry this creates a loophole—crypto products dressed as traditional instruments to dodge stricter rules.

What this lobbying reveals about MiCA's operational constraints
The lobbying campaigns expose where MiCA's requirements bite hardest. It's not the disclosure rules or the whitepapers—it's the capital lockup, the custody mandates, and the reserve composition. These are cash constraints, not paperwork. A platform holding customer crypto under MiCA's segregation rules can't rehypothecate those assets or use them as collateral elsewhere. A stablecoin issuer forced to diversify reserves pays for multiple banking relationships and accepts basis risk across asset classes.
For builders, this maps to architectural decisions. If you're designing a perps exchange for EU users, you need to decide: do you seek a MiCA license and accept higher capital costs, or do you lobby for MiFID II treatment and build for traditional derivatives infrastructure? If you're issuing a stablecoin, do you comply with MiCA's reserve rules and operate in the EU, or do you stay offshore and accept that EU payment processors might freeze you out?
The lobbying also reveals a timing mismatch. MiCA was drafted when DeFi was nascent and most crypto activity happened on centralized exchanges. By the time it took effect, onchain perps, automated market makers (AMMs), and algorithmic stablecoins had matured. The rulebook doesn't cleanly fit these models. Platforms are arguing that MiCA's categories—crypto-asset service provider, e-money token, asset-referenced token—don't map to how products actually work. This gap is why lobbying focuses on definitions, not just compliance thresholds.
Another constraint: MiCA's proof-of-reserves requirement. Platforms must hire auditors to verify that customer assets are held 1:1 and segregated. For a centralized exchange with a database of account balances, this is straightforward. For a platform with onchain settlement or a hybrid custody model, it's ambiguous. What counts as a reserve if assets are locked in a smart contract? Who audits a multi-sig wallet? The lobbying here isn't asking for exemptions—it's asking for clarity so platforms know what to build.
What this means for builders
Watch ESMA's review process. The next 18 months will determine whether MiCA's scope narrows—perps move to MiFID II, reserve rules loosen—or expands with stricter custody rules and DeFi protocol obligations. Either outcome changes your compliance roadmap and product design.
Start planning dual-regime scenarios. If perps stay under MiCA, you need higher capital reserves and tighter leverage limits. If they move to MiFID II, you need a different license and possibly a different legal entity. Build modular compliance tooling that can adapt to rule changes without rebuilding your stack.
For stablecoin integrations, don't assume current issuers will remain compliant. If Circle or Tether can't meet MiCA's reserve rules, you need fallback stables that can. Consider whether your protocol can handle reserve transparency—users might demand proof-of-reserves for any stablecoin touching EU wallets.
Recognize that regulatory arbitrage will shape where products live. If MiCA's costs are prohibitive, platforms will route EU users to offshore entities or MiFID II-licensed subsidiaries. This fragmentation matters for liquidity, custody, and API integrations. Build for a world where the same product has different compliance wrappers depending on jurisdiction.
Conclusion
The lobbying around MiCA is a negotiation over what kinds of crypto products can exist in Europe and at what cost. Platforms are testing whether they can redefine perps as traditional derivatives, push back on reserve diversification, and win concessions before MiCA's review locks the rules in. The outcome will set precedent far beyond the EU. Regulators in the UK, Asia, and eventually the U.S. are watching how Europe handles the boundary between crypto and traditional finance. For builders, this means understanding the constraints you'll work within and designing systems flexible enough to survive regulatory shifts.
