The number of banks with a non-transparent ownership structure fell from 67 as of middle of 2015 to 48, and their assets' share of the total assets of the banking system represented by 121 banks is now only 7%, First Deputy Governor of the National Bank of Ukraine (NBU) Oleksandr Pysaruk has said.

"Almost all the banks on the list are cooperating with the National Bank. We plant to finish the work on ensuring transparency of the ownership structure by the end of Q1 2016," he said at a press conference in Kyiv on Thursday.

Pysaruk said that the list of 48 banks presented by the NBU at the press conference should not be treated as a black list.

"This is a working list, and it says nothing bad about the banks. I don't see the likelihood that the banks from the list would be sent to the [Individuals' Deposit] Guarantee Fund due to this reason," he said.

He added that during the disclosure of the ultimate beneficiaries of banks, the NBU only used the sanction of declaring banks as troubled twice, and in both cases the sanction solved the problem.

He said that banks declared by NBU insolvent often have non-transparent ownership structure. In particular, since the middle of 2015 there were 11 banks with the non-transparent ownership structure that were declared insolvent.

There are nine banks on the list of 48 banks which almost finished the agreement procedure with the NBU, and it takes around six months to pass it.

Among them are Agrarian Commercial bank, Aktsent-Bank, Asvio Bank, Veles, Commercial Investment Bank, First Investment Bank, Portal, Promyslovo-Finansovy Bank and TAScombank.

Among other 39 banks are Avant-Bank, Alpari Bank, Alliance, Arkada, Vector Bank, Gefest, globus, DV Bank, Express-bank, Land Capital, Investbank, Bank of Investment and Saving, Investment-Trust Bank, Industrialbank, Commercial Industrial Bank, Classicbank, Clearing House, Credit Dnepr, Crystalbank, KSG Bank, bank Lviv, Misto Bank, Motor-bank, Neos Bank, Bank People's Capital, Novy, Petrocommerce-Ukraine, Platinum bank, Policombank, Premium, Smartbank, TK Credit, Ukrainian Capital, Unicombank, Finance bank, Finexbank, Center and Unison.
