Russia will introduce legislation this week that would compel banks and payment processors to block transactions with international online gambling sites.

On Sunday, Russian media outlet RBC.ru reported that the Ministry of Finance had crafted a new bill that aims to stop the flow of money – estimated at $3b per year – between Russian gamblers and international online gambling operators. The proposed legislation will be discussed at a government meeting on Thursday (16).

The bill would task the Federal Task Service (FTS) with creating a blacklist of both Russian and international companies and individuals involved in unauthorized online gambling activities. The list would be distributed to Russian financial institutions, which would be responsible for blocking transactions involving these blacklisted companies and individuals.

The bill was originally proposed by the Ministry of Finance in 2015, but the initial draft met with resistance from some other government ministries, as well as from some major Russian financial institutions, which were concerned about bearing the cost of monitoring for unauthorized gambling payments. The other government ministries are reportedly now on board with the revised legislation, the specifics of which have yet to be made public.
