Bulgaria Euro Adoption Reshapes Housing Construction

Bulgaria's adoption of the euro on 1 January 2026 is reshaping its residential construction market, following record completions of residential buildings and dwellings in 2025.

Property transactions have since declined, while construction permits, housing starts and mortgage lending have followed different trends, according to an analysis by the Economic Policy Institute and EECFA.

Bulgaria's Euro Adoption and Residential Construction

Bulgaria became the 21st member of the euro area on 1 January 2026, after nearly 30 years of maintaining a fixed exchange rate first linked to the Deutsche Mark and later to the euro.

Several factors contributed to the record residential construction completions in 2025.

These included concerns about potential price increases following the currency changeover, existing inflationary pressure, favourable financial conditions and substantial cash holdings that needed to be invested quickly.

Yasen Georgiev, Bulgaria researcher at the Economic Policy Institute and EECFA, said the immediate effects of euro adoption could already be assessed to some extent, although conclusions depended on the available data.

Property Transactions Decline in 2026

Bulgarian property sales recorded a clear downward trend between January and September 2026, with the pace of decline accelerating during the year.

In the third quarter of 2026, 45,312 property sales were registered, a 22% decline from 58,184 transactions in the same period of 2025. The annual decline had reached 18% in the second quarter and 15% in the first quarter.

The figures indicate that transaction activity weakened following the currency changeover. However, the available data does not establish that euro adoption alone caused the decline.

Construction Permits and Housing Starts Show Mixed Trends

Construction indicators presented a more varied picture. Measured by floor area, residential construction permits increased by 33% year on year in the first quarter of 2026 and by 4% in the second quarter.

The floor area of construction starts rose by 58% in Q1 and 9% in Q2 compared with the corresponding periods of 2025.

These figures suggest that new development activity continued to expand, although growth slowed considerably in the second quarter.

Completed floor area moved in the opposite direction. It fell by 44% between January and March 2026 and by 24% between April and June compared with the same periods a year earlier.

The declines suggest that the previous peak in residential completions may have passed.

Housing Loans Continue to Grow

Despite weaker property sales, new housing lending continued to increase. Data from the Bulgarian National Bank showed that the volume of new housing loans in August 2026 was 21% higher year on year.

Continuously low interest rates supported this growth. The divergence between declining transactions and rising housing lending highlights the mixed conditions affecting Bulgaria's residential property market.

Further Assessment Expected in December

Georgiev cautioned that it remains too early to draw firm conclusions about the impact of euro adoption on residential construction. The effects need to be assessed alongside changes in transaction activity, construction indicators and financing conditions.

EECFA plans to publish a clearer assessment in its winter construction forecast report on 8 December 2026. The report is expected to provide further analysis of developments in Bulgaria's construction sector.
