The National Securities and Stock Market Commission of Ukraine has approved new rules requiring organized capital market operators and investment firms to monitor suspicious orders and transactions and report them to the commission using the Suspicious Transaction and Order Report standard. The framework aligns Ukrainian requirements with the European Union Market Abuse Regulation and replaces rules in place since 2011. Following public consultation, the commission limited the requirement for investment firms to use specialized monitoring software to cases involving algorithmic trading. Professional participants may determine their own risk indicators based on a nonbinding commission list. Where several participants execute the same transaction, they will share responsibility for analyzing it and submitting a report. The rules will apply from 2027, and market participants must update their internal procedures before then.
