According to the Kazakhstan Stock Exchange (KASE), American sanctions against the Moscow Exchange (MOEX) won’t bring any legal consequences for KASE, as the Russian exchange controls just a small fraction of it.
On June 12, the U.S. Office of Foreign Assets Control (OFAC) of the U.S. Department of the Treasury added the Moscow Exchange (MOEX) to its SDN list, which means all its accounts in American banks and depositories must be blocked, whereas US citizens and entities are prohibited from any sort of cooperation with the exchange. MOEX already announced that it would stop trading with US dollars and euros.
