As part of its strategy to deliver steady growth while maintaining a low-risk profile, the Bulgaria AIF Fund has acquired one lot of the Bulgarian Energy Holding (BEH) bond with a nominal value of €100,000 and a 4.25% annual coupon. While this represents only a small fraction of the total €800 million issuance, the investment plays a vital role in diversifying the Fund’s fixed-income portfolio.

Who Is Bulgarian Energy Holding?

BEH is a government-owned holding company and the backbone of Bulgaria’s energy sector. Its subsidiaries operate across three strategic areas:

Electricity Production and Transmission

BEH subsidiaries such as National Electric Company (NEK), Kozloduy Nuclear Power Plant, Maritsa East 2 TPP, and the Electricity System Operator (ESO) generate power from nuclear, thermal, and hydro sources. NEK buys and sells electricity both on regulated and free markets, while ESO manages Bulgaria’s electricity transmission grid.

Natural Gas Supply and Transit

Through Bulgargaz EAD and Bulgartransgaz EAD, BEH plays a central role in Bulgaria’s natural gas sector. Bulgargaz is the public supplier of natural gas, while Bulgartransgaz manages transmission, transit pipelines, and underground gas storage.

Coal Mining

Mini Maritsa-Iztok EAD is Bulgaria’s largest lignite coal mining company, providing over 90% of the lignite coal used for thermal power plants, including Maritsa East 2 TPP. With reserves estimated at 2.1 billion tonnes and an annual capacity of 35 million tonnes, the mines are expected to cover demand for another 60–70 years. The company operates under a 35-year concession granted by the government in 2005. Coal from Maritsa-Iztok powers more than 25% of Bulgaria’s electricity production.

Is the 4.25% Yield Attractive?

Given BEH’s government ownership and critical infrastructure role, its bonds are seen as very secure instruments. However, the 4.25% yield is modest compared to other corporate bonds on the Bulgarian market—particularly after adjusting for inflation and transaction costs.

For investors in the Bulgaria Golden Visa Program, this bond serves as a diversification tool, providing a more secure fixed-income instrument with a low-risk profile that aligns well with the program’s objectives.

Why Reinvesting Coupons Can Improve Returns

In theory, compounding BEH’s coupons at 4.25% produces an effective annual yield of around 4.32%. In practice, reinvesting the coupons into smaller-lot bonds or higher-yield instruments (7–8% annually) can lift the portfolio’s blended return above pure compounding.

For example, five years of BEH coupons total €21,250. Redirecting this into a 7% bond would generate additional gains, helping the overall portfolio outperform simple compound interest while still keeping a low risk profile.
