On Tuesday, BlackRock, which runs the iShares family of ETFs, issued a notice to investors announcing it's suspending the creation of new shares in the fund.
"The liquidity of Russian securities and its currency has experienced significant declines. In light of these circumstances, the iShares MSCI Russia ETF has temporarily suspended the creation of new shares until further notice," it said.
"BlackRock cautions investors that ERUS may not meet its investment objective, may experience increased tracking error, may experience significant premiums or discounts to its net asset value (NAV), and/or have bid-ask spreads wider than its historical average," it added in reference to buying shares on the secondary market.
On Tuesday, Visa and Mastercard blocked "multiple financial institutions" in Russia from their networks in response to government sanctions on Russian entities, preventing Russians from using their credit cards.
That move comes after the European Union, U.K., U.S. and Canada pledged to remove selected Russian banks from SWIFT, or the Society for Worldwide Interbank Financial Telecommunication, thereby severing them from most of the global financial system.
