In June 2012, OeEB provided EUR 30 million to the Black Sea Trade & Development Bank (BSTDB) for the first time. Since then, the funds have been increased several times. Most recently, a loan of EUR 20 million was granted in December 2025.

Due to the tense geopolitical environment, the BSTDB has only limited access to long-term capital market financing and is therefore heavily dependent on development finance institutions. There are significant financing gaps for sustainable projects, particularly in high-risk markets.
OeEB's long-term credit line to the BSTDB strengthens the financing of sustainable projects in the Black Sea region in the area of green finance and, through investments in the target countries, contributes to reducing dependence on fossil fuel imports (Russia) and strengthening economic resilience and regional stability
