PSB Moves to Russian Software to Boost Financial Sovereignty
Russia’s PSB bank has fully migrated its investment app to a domestic software platform, marking a major step toward digital sovereignty in the financial sector.
Seamless Transition to Russian Infrastructure
Promsvyazbank (PSB) has migrated its investment platform, PSB Investments, entirely to a Russian-developed technology stack. The shift was invisible to users—no app reinstallations were required, and both the mobile and desktop interfaces remained unchanged.
This behind-the-scenes overhaul insulates PSB’s investment services from external threats, such as license revocations or sanctions-based service cutoffs. It also enhances data security and improves responsiveness to user demands, especially during trading operations.
Minimizing Risk in a Tense Geopolitical Climate
The project was tailored to Russia’s domestic capital market, reinforcing investor confidence in a climate of ongoing global uncertainty. By developing local IT infrastructure and strengthening cybersecurity, PSB offers clients reliable access to investment tools—independent of foreign software vendors.
PSB is among the last major Russian banks to complete its digital transition, making its tech overhaul a milestone in the country’s import substitution program and a cornerstone in securing financial-sector sovereignty.
VTB Case Study: A Similar Path
Another major player, VTB Bank, took a similar approach. Its brokerage division transitioned to a fully Russian-built digital platform for its “VTB My Investments” app. The new system ensures compliance with national regulations and removes all reliance on international software providers.
“In 2025, our brokerage finalized the shift to 100% Russian-developed software. Everything from trading engines to client service infrastructure is now independent of foreign vendors. We built most of the solutions from scratch using modern technologies,” said Andrey Yatskov, head of brokerage services at VTB, in an interview with RBC.
Earlier, VTB migrated its big data analytics platform to Arenadata Hadoop, doubling processing capacity and supporting over 300 AI models, including credit scoring, income assessment, and anti-fraud systems.
A Growing Fintech Movement
The success stories of PSB and VTB could prompt other market players to follow suit. While not every financial institution has in-house development capabilities, many can adopt market-ready domestic solutions to support their digital transformations.
In Russia, software import substitution is no longer experimental—it has become a full-scale, irreversible shift. The financial system is increasingly shielded from foreign influence and external shocks thanks to this transition.
