What happened: the regulator lost in court for the second time in a row
Ukraine's central bank, the NBU, has lost another round of a legal dispute with International Investment Bank (IIB) — a financial institution nearly 65%-controlled by former president Petro Poroshenko. In February 2025, the NBU issued the bank a written warning over anti-money-laundering (AML) violations: according to the regulator, IIB improperly assessed client risk and failed to provide accurate information and documents to the NBU within the required deadlines.
The bank challenged the decision in court — and won. In December 2025, the Kyiv District Administrative Court ruled the NBU's warning unlawful and cancelled it. The regulator appealed, but on 30 June 2026 the Sixth Administrative Court of Appeal upheld the first-instance ruling. The NBU has already stated it disagrees with the courts' conclusions and intends to appeal further to the Supreme Court in cassation — so this case is far from over.
What a "written warning" actually is, and why it mattered
A written warning is the mildest supervisory tool the NBU applies to banks. It is not a ban on operations, not a restriction on cash withdrawals, and not a reason for depositors to worry — in essence, it is a formal notice: "we see a problem in your internal procedures, fix it." But for the bank itself, such a record carries weight: it stays on the supervisory file, can affect the bank's standing in negotiations with foreign correspondent partners, and can become grounds for tougher measures if violations recur.
That is precisely why banks rarely take such disputes to court — far more often they simply agree with the regulator and quietly fix the shortcomings. The fact that IIB went to court and won two instances in a row is unusual. It shows that even the NBU's supervisory decisions are not automatically beyond question and are subject to full judicial review if a bank considers them unjustified.
Why this precedent matters beyond the two parties involved
Context matters here: in March 2025 the NBU simultaneously applied enforcement measures to six banks and three non-bank financial institutions for violations in the field of AML and currency legislation — IIB was one of them. In other words, this is not an isolated case but part of a broader wave of checks the regulator carried out amid tightening transparency requirements across the banking sector. Within the same broader standoff, the NBU also fined IIB 14.5 million hryvnia, and in autumn 2025 it barred Poroshenko from exercising voting rights on his roughly 65% stake in the bank — separate proceedings that continue in parallel and are not affected by this particular court ruling.
For the sector as a whole, the regulator's court loss is a signal that the quality of supervisory documentation and the justification behind enforcement actions matter, even for the mildest of tools. For other banks, this is more of a procedural lesson than a reason to relax: AML requirements are not going away, and the NBU has already announced it will keep pursuing the case through cassation.
What this means for an ordinary bank customer
The key thing to understand: a written warning is not a signal to "pull your money out immediately." It is a supervisory tool concerning a bank's internal procedures, not its financial stability or its ability to meet obligations to customers. Funds held in accounts and deposits at any NBU-licensed Ukrainian bank remain protected by the state guarantee through the Deposit Guarantee Fund, up to the established reimbursement limit.
Still, the situation is a good reminder of a few practical points:
- Supervisory disputes and court proceedings between a bank and the NBU are public information — it is worth checking the news about your main bank, or the one where you hold a business account, every few months.
- Stricter AML monitoring at a bank can mean extra document requests during transfers or large withdrawals — this is not a reason to panic, but a standard practice that is only becoming stricter across the entire banking system.
- When choosing a bank for a salary account, savings, or business needs, it pays to look beyond how recognisable the brand or owner is, and focus on actual terms — rates, fees, app convenience, and supervisory track record.
- Spreading savings across several banks reduces your exposure to the reputational or supervisory risk of any single institution.
Making bank decisions based on data, not headlines
News about court battles surrounding a specific bank easily triggers an emotional reaction — especially when a well-known public figure is involved. But for the practical question of "where should I keep my money", it is far more useful to look at current market-wide conditions. If you are planning to open a new account for everyday spending, it is worth checking the ranking of the best personal accounts, which gathers up-to-date terms from different banks in one place.
If you are building an emergency fund or simply don't want your money sitting idle, compare current offers in the savings accounts ranking — the terms there are updated regularly and reflect the real market picture rather than marketing promises. And if you're looking at fixed-term deposits with a locked-in rate, you can compare current offers in the deposits ranking.
This approach — comparing real, regularly updated terms instead of relying on brand recognition or dramatic court headlines — is a far more reliable way to protect your finances at a time when even a regulator's decisions can be overturned in court.
Bottom line: what to do now
The NBU's court loss to Poroshenko's bank is, above all, a story about supervisory practice, not about the financial stability of any particular institution. The case isn't over — the regulator is heading to cassation, so a final resolution is still a way off. For depositors, this is a reason not to panic but to build the habit of regularly checking the news and terms tied to their own bank, and not keeping all their savings in one place. Start by comparing current terms and pick the option that actually fits your needs, rather than just the name on the sign.
