Overview
Starcom Holding AD, a major Bulgarian investment group, and its majority shareholder, Assen Christov, have delivered a formal notice to both the Central Bank and the Government of San Marino. The notice signals their intent to commence international arbitration at the International Centre for Settlement of Investment Disputes (ICSID) in Washington, citing significant financial losses relating to their investment in Banca di San Marino.
What Happened
On April 1, 2026, Starcom Holding AD and Assen Christov announced they have notified San Marino authorities of an upcoming ICSID arbitration regarding their investment in Banca di San Marino.
They allege that certain high-ranking officials from San Marino's regulatory and judicial institutions acted illegitimately, violating international regulations and causing financial harm to the Bulgarian investors.
According to Starcom, authorities in San Marino have failed to address these concerns or engage in meaningful dialogue, prompting the move towards arbitration for damages of at least €150 million.
Pinsent Masons, an international law firm, will represent Starcom and its management. The final claim could proceed unless an agreement is reached in pre-arbitration negotiations.
Context
Starcom Holding is a significant Bulgarian investor with interests in energy and finance across 12 European countries and consolidated assets of approximately €1.7 billion. Their investment in Banca di San Marino, planned through the San Marino Group (a special purpose vehicle), is among the largest in San Marino in the past two decades.
The case highlights tensions between an international investor and a small European jurisdiction, especially as San Marino is seeking to strengthen ties with the European Union and its single financial market.
Why It Matters
- This potential arbitration could set precedents for foreign investor protections in San Marino and similar microstates.
- The outcome may affect San Marino's reputation with international investors and its negotiations with the European Union.
- It underscores challenges for investors in securing cross-border legal protections and for states in managing investment disputes in the financial sector.
