GAZP (direct exposure)
What Happened
US and EU sanctions prevent Russian entities from renewing security certificates (HTTPS/SSL certificates) used to secure websites, banking systems, email, and government infrastructure. As certificates expire, Russian systems face exposure to man-in-the-middle attacks, credential theft, and data interception. The vulnerability affects critical financial and government systems across Russia.
How This Reaches Markets
Expiration of security certificates compromises the integrity of Russian financial transaction systems and creates operational risk for Russian banks and energy companies. Compromised banking infrastructure increases transaction risk and operational costs for Russian entities. This amplifies the economic disruption from existing sanctions by degrading operational continuity.
