Previous fines embody €4 million for Kraken and €2.85 million for Crypto.com.
OKX additionally fined €1.1 million in Malta in April 2025.
$504 million settlement within the US retains OKX beneath oversight till 2027.
The Dutch central financial institution’s resolution to positive OKX €2.25 million is not only a warning about regulatory oversight—it displays how European authorities are taking a retrospective strategy to compliance.

By concentrating on previous exercise, regulators are making it clear that crypto exchanges will likely be held accountable even for legacy practices, no matter whether or not they’re now licensed beneath Europe’s new regime.
Previous actions stay beneath scrutiny

OKX, working with out approval throughout that timeframe, was present in breach. The DNB mentioned such violations “won’t be tolerated.”
The Netherlands has taken related motion towards different main exchanges.
Kraken paid €4 million, and Crypto.com paid €2.85 million, each for providing unregistered companies.
These penalties, together with OKX’s newest positive, present that enforcement applies retroactively and that regulators will not be letting previous violations slide because the trade adapts to new frameworks.

These fines present a constant sample: regulators are digging into earlier operations whereas demanding present compliance.
For exchanges, this implies penalties could arrive years after the unique breaches, creating extended uncertainty.
Dutch case handled as “legacy matter”
OKX, legally often called Aux Cayes Fintech Co., characterised the Dutch case as a “legacy matter” and mentioned it has already resolved the difficulty.
Dutch prospects had been moved to its MiCA-licensed European entity, and the agency harassed there was no impression on prospects.
The positive imposed by the DNB was decrease than penalties given to different exchanges, with the regulator recognising OKX’s cooperation.
Nonetheless, the motion reinforces a bigger pattern: exchanges can’t merely comply at present and ignore yesterday.
Europe’s enforcement period beneath MiCA
The timing of the Dutch case is critical. MiCA is now dwell throughout Europe, requiring exchanges to register, adjust to reporting guidelines, and go stricter anti-money laundering checks.
Whereas OKX and others have secured licences, regulators are nonetheless pursuing earlier breaches.
This implies the period of “function first, register later” has ended, and exchanges are studying that legacy operations carry dangers lengthy after new frameworks are in place.
The Netherlands’ strategy signifies that different regulators throughout Europe could comply with, reviewing previous exercise whereas imposing present guidelines.
