Bulgaria's gross external debt, including both the public and private sectors, is experiencing significant growth, according to the latest information published by the Bulgarian National Bank (BNB). According to preliminary data, as of the end of August this year, the liabilities reached 53.605 billion euros, which represents an increase of 20.2% year-on-year.
Observing the trend in the long term, the dynamics of the debt are clearly visible. For comparison, at the end of August of the previous year, the gross external debt was significantly lower, amounting to 44.590 billion euros. This means that for the year the debt increased by an impressive 9.015 billion euros.
The current size of the gross external debt equals 47.7% of the projected gross domestic product (GDP) of the country. This figure highlights a significant increase compared to the reported 42.6% of GDP at the end of the same period of the previous year.
The analysis of the debt structure reveals interesting details. As of the end of August 2025, short-term liabilities amount to 8.700 billion euros. This represents 16.2% of the total gross debt and 7.7% of GDP. Compared to August 2024, when these liabilities were 8.197 billion euros, the increase is significant - 503.3 million euros, which represents a growth of 6.1%.
Long-term liabilities form the larger part of the external debt. As of the end of August 2025, they amount to 44.905 billion euros, which represents 83.8% of the gross debt and 40% of GDP.
