In a statement on LinkedIn, Fink said American brands like McDonald's Corp, PepsiCo, and Visa Inc suspending or curtailing their operations in Russia was helping isolate the country's economy from the global financial system and showed the commitment of major brands to "go beyond profit".

Western sanctions on Moscow have led a slew of investors to announce they were cutting positions in Russia. Authorities in Russia, however, have banned local brokers from selling securities held by foreigners.
