NBU introduces new requirements: how the rules for the banking system will change
9 March 20:08
From January 1, 2027, banks and banking groups in Ukraine will be required to form additional capital buffers.
This was announced by the National Bank of Ukraine, according to "Komersant Ukrainian".
The regulator has set:
- a capital conservation buffer of 2.5% for all banks
- a systemic importance buffer of 1% to 2%, depending on the bank’s status
The new requirements were approved by a resolution of the NBU Board on March 4, 2026.
What are capital buffers?
Capital buffers are financial reserves that banks accumulate during periods of economic growth.
It is used to:
- cover potential losses during crises
- maintain the stability of the banking system
- prevent lending to the economy from stopping
The National Bank of Ukraine explains that such mechanisms enable banks to withstand financial and economic shocks.
Approximation to EU standards
The new rules also change the minimum capital adequacy requirements to bring them into line with European legislation.
In particular, the following indicators are established:
- 8% — regulatory capital adequacy ratio
- 6% — Tier 1 capital adequacy
- 4.5% — Tier 1 capital adequacy
These values correspond to the approaches used in European Union banking regulation.
Why are the rules changing?
According to the National Bank of Ukraine, Ukrainian banks previously did not have separate capital buffers.
Their role was effectively performed by increased minimum capital adequacy ratios.
Now, after the introduction of buffers, the need for such inflated indicators disappears.
How this will affect banks and lending
The NBU emphasizes that the transition period until 2027 gives banks enough time to adapt.
The introduction of the new rules is expected to:
- will not slow down the pace of lending to the economy
- increase the stability of the banking system
- bring Ukraine’s financial regulation closer to EU standards
Ukraine’s financial indicators
Against the backdrop of changes in banking regulation, the financial sector also faces other challenges.
According to the National Bank of Ukraine:
- Ukraine’s international reserves as of March 1 amounted to $54.75 billion, which is 5% less than a month earlier;
- the NBU’s electronic payment system remains the only systemically important payment system;
- the regulator previously lowered its inflation forecast for 2026 due to the consequences of attacks on energy infrastructure.
The new capital requirements are expected to be another element in strengthening the country’s financial stability.
