New research from crypto data firm Kaiko shows that EUR fiat pairs are pulling the majority of euro-denominated crypto trading volume. The finding lands squarely on the stablecoin crowd: traders in the currency bloc are choosing direct euro transactions over dollar- or euro-pegged tokens when it's time to move in and out of positions.
That's a meaningful signal. Stablecoins have dominated crypto's cash leg for years, but the eurozone's trading desks appear to be taking a different route. Kaiko's report frames the pattern as a straightforward preference for direct transactions — no intermediary token, no extra conversion step.
Where the volume is going
Kaiko's data doesn't just show that EUR pairs are popular. It shows they're the primary vehicle for euro trading, which means the fiat-to-crypto on-ramps and off-ramps that connect to European banking rails are doing the heavy lifting. For traders, that's a practical choice: fewer hops between a bank account and a position.
The knock-on effect for stablecoins is harder to ignore. If euro traders consistently skip stablecoin pairs, the case for a widely used euro-denominated stablecoin gets weaker, not stronger. Adoption depends on volume, and volume is going elsewhere.
Stablecoin projects have spent years pitching themselves as the default trading pair for non-dollar markets. Kaiko's finding challenges that pitch in one of crypto's biggest regional markets. It doesn't mean stablecoins are losing ground everywhere — the report is specific to euro trading — but it does mean the eurozone is a tougher sell than the marketing implies.
There's also a market-structure angle. Direct fiat pairs tend to concentrate liquidity on a smaller set of venues that can support banking relationships and regulatory compliance. That can cut both ways: tighter spreads in normal conditions, but thinner books when volatility spikes and traders rush for the exits.
The regulatory backdrop
Europe's crypto rulebook has been in force for a while now, and it has pushed more trading activity toward regulated venues with proper fiat plumbing. That environment naturally favors direct EUR pairs over stablecoin routes that may sit in a murkier compliance zone. Kaiko doesn't draw that line explicitly, but the preference it documents lines up with how the market has been reshaped.
What Kaiko's report doesn't settle is whether this is a durable shift or a snapshot of current conditions. Stablecoin issuers will keep pushing euro products, and exchanges will keep listing whatever pairs their users actually trade. The next round of volume data should tell us whether EUR pairs hold their lead — or whether the stablecoin camp finds a way back into the eurozone's order books.
