MiCA drives over 100% year-on-year growth in euro stablecoin market capitalization, but European crypto trading still faces an "invisible liquidity trap"

With the European Union’s Markets in Crypto-Assets Regulation (MiCA) officially coming into effect in 2024, the euro stablecoin has entered a long-awaited growth cycle. Data shows that within 12 months of MiCA’s implementation, the market capitalization of major euro stablecoins increased by over 100% year-on-year, completely reversing the previous downward trend. By mid-2025, the total market cap of euro stablecoins approached $500 million, and monthly trading volume surged from less than $400 million to $3.8 billion, with EURC and EURCV leading the growth.

On the surface, euro stablecoins are rapidly “reviving,” and the European cryptocurrency market seems to be experiencing a better liquidity environment. However, the key issues that truly impact traders’ execution prices are hidden within the trading venues and order book structures.

Research data indicates that the rapid expansion of the euro stablecoin market is not entirely driven by new demand but is more a result of market restructuring under regulatory pressure. After MiCA clarified compliance thresholds, exchanges focused on delisting non-compliant products, and the market share of compliant euro stablecoins quickly increased, once exceeding 90%. However, at the same time, the overall weekly trading volume of euro stablecoins has not returned to historical highs, indicating that “market share growth” does not equate to “real liquidity increase.”

Regarding euro trading of Bitcoin and Ethereum, improvements in execution quality are more due to highly concentrated liquidity rather than the prosperity of stablecoins themselves. Data shows that BTC-EUR accounts for nearly 10% of global Bitcoin fiat trading, significantly higher than previous levels. However, these trading volumes are highly concentrated on a few platforms, with four CEXs accounting for over 85% of euro trading volume, and one, Bitvavo, approaching half.

The result of this concentration is that the bid-ask spreads at leading exchanges have narrowed significantly, with some platforms seeing BTC-EUR average spreads as low as 2–3 basis points, while others remain above 20 basis points. The same applies to market depth: high-quality platforms can handle large trades without significantly impacting prices, but the execution costs on long-tail exchanges remain relatively high.

The true value of euro stablecoins lies in reducing friction in fund transfers and cross-platform rebalancing, especially when bank transfers are restricted or during non-working hours. However, they do not automatically improve slippage for all BTC-EUR or ETH-EUR trading pairs. Platforms with active stablecoin trading may not necessarily offer the best spot execution quality, and this “trading venue gap” is a risk many traders overlook.

Overall, MiCA has indeed achieved its regulatory goals in the first year: clearer rules, more compliant products, and euro stablecoins regaining scalability. But for traders, the improvement in European cryptocurrency liquidity appears more concentrated in a few “habitable islands” rather than a comprehensive upgrade. The true determinants of execution prices remain the choice of exchanges, market depth, and liquidity distribution, rather than simply the growth in stablecoin market cap.
