The Secret Of Sanctions On Russia Effects - Big Bank CEO Explains

The primary reason for U.S. bank sanctions on Russia is Russia's invasion of Ukraine in February 2022. 

 The United States, along with its allies, imposed severe financial sanctions on Russian banks and financial institutions to punish Russia for violating Ukraine's sovereignty and territorial integrity. These sanctions aim to:
 

Weaken Russia's financial system: By restricting access to international financial markets, blocking transactions, and freezing assets, the sanctions limit Russia’s ability to finance its military operations.
 

Target major Russian banks: Institutions like Sberbank and VTB, which hold a significant portion of Russia’s banking assets, were sanctioned to isolate Russia from the global economy.
 

Pressure on Russia's elite: These measures also target individuals close to the Kremlin to create political pressure on President Vladimir Putin's government.

In short, the sanctions are a part of the broader Western strategy to economically isolate Russia in response to its aggression in Ukraine.
