Bulgaria's economy: run by a currency rule since 1997

Why the lev was fixed and left alone

Late in 1996 the Bulgarian banking system was failing and prices were accelerating toward hyperinflation. A review that year found that nine of the ten state banks, which between them held more than 80% of banking assets, had negative capital, and that more than half of their portfolios were not performing. Half of the private banks were technically bankrupt as well. Banks accounting for about a third of the system were closed across two rounds of closures in 1996, and real output contracted by more than 10% that year.

The monetary figures moved faster than the banking ones. Annualised inflation reached almost 500% in January 1997 and passed 2,000% in March. The lev fell from 487 to 1,588 to the United States dollar over the first quarter of 1997. Tax revenue dropped from almost 40% of GDP on an annualised basis to 14.7% in February 1997, and the central bank, having spent its reserves slowing the currency's fall, was left holding cover for less than two months of imports.

An International Monetary Fund mission opened discussions on a currency board in November 1996, with political parties, trade unions, journalists and academics as well as the government, and the decision was taken only when a new administration came in during the spring of 1997. Parliament passed the amended central bank law on 5 June 1997 and the arrangement began on 1 July. The anchor chosen was the deutsche mark, argued for against the dollar on the grounds that it fitted the country's trade and its intended direction in Europe. The rate was set at 1,000 leva to one mark on 5 June; the market rate five days earlier had been 922.41.

The Bulgarian National Bank was rebuilt around the rule. It was split into an issue department, a banking department and banking supervision, on the Bank of England model. The issue department holds the bank's monetary liabilities and has to hold foreign exchange and gold covering them in full at all times, and its accounts are published weekly. Two provisions of the new law ended large-scale monetary financing of the budget, and a fiscal reserve account held inside the issue department, fully covered by reserves, became the measure of what the government actually had available to spend.

What the rule bought in eighteen months

Inflation fell to 13% by the middle of 1998 and to 1% by the end of that year. Foreign exchange reserves rose from less than 800 million dollars to more than 3 billion, which was cover for more than six months of imports. The central bank's basic interest rate, above 200% at the height of the crisis, stood at 5.2% at the end of 1998, and retail rates moved close to German levels as soon as the board opened. No bank had to be supported through the banking department during the arrangement's first two years, and the stabilisation held through Russia's crisis of mid-1998 despite close economic ties between the two countries.

Living standards took far longer to recover than the price level did. The standard of living had fallen by about 40% during the early 1990s and regained its pre-1989 level in June 2004. Growth came with privatisation and the approach of European Union membership: 5.0% in 2003, 6.6% in 2004 and 6.0% in 2008.

Public borrowing followed the same discipline. State debt stood at 11.25 billion dollars in 1991, equal to 180% of GDP, and peaked at 14.4 billion in 1994. A decade of budget surpluses brought it down to 5.07 billion euro by 2008, or 13.7% of GDP, against a fiscal reserve of 4.286 billion euro in the same year. It rose again to 18.1% of GDP at the end of 2013 and to 26.7% in 2015, part of that increase driven by the failure of Corporate Commercial Bank in 2014 and the payout of guaranteed deposits that followed.

How the tax system was built to match

Corporate income tax was set at a flat 10% from 1 January 2007 and personal income tax at the same rate from 1 January 2008. The change was described at the time as a revolution in taxation and drew protests from some of the working households it affected, and the proposal was modified to compensate those who lost by it. Most state revenue still comes from value-added tax and excise duties, though the share taken by income and corporate taxes has been rising.

Fiscal policy carried the weight the exchange rate could not. Annual surpluses ran above 3% of GDP in the years around accession, and government indebtedness fell to 22.8% of GDP in 2006 from 67.3% five years earlier.

Foreign investment answered slowly and then all at once. Total direct foreign investment between 1991 and 1996 came to 831 million dollars, held down by slow privatisation, changeable tax and investment rules and administrative delay. In 2004 alone foreign companies invested more than 2.72 billion euro. The figure fell to about 1.8 billion euro in 2005 as the privatisation of the large state companies ran out, then peaked at about 6 billion euro after European Union accession on 1 January 2007. The largest national sources in 2003 were Austria, Greece, Germany, Italy and the Netherlands.

What the tax rate did not buy was research. Spending on scientific research was 0.25% of GDP in 2010, and the underinvestment since 1990 shows up in how little of what leaves the country carries a high margin.

What the country still makes and mines

Manufacturing and mining employ almost a fifth of the labour force, and more than a third of the active workforce is in trade and services. The industrial base was assembled under central planning and configured for Soviet markets, so the end of Comecon in 1991 removed the customer rather than the capacity.

What survived the loss of Soviet markets

Food and tobacco processing lost their markets and did not reach standards that would sell in Western Europe. Textile processing declined from the middle of the 1990s, although clothing exports have grown steadily since 2000. The manufacture of cars, trucks and buses stopped altogether, and so did the manufacture of forklift trucks, which had been a speciality of the communist period.

What survived tended to survive through a foreign buyer. LUKoil bought the Neftochim refinery at Burgas in 1999 and modernised it in 2005. Union Minière of Belgium bought the copper smelting plant at Pirdop, which lifted non-ferrous metallurgy. Shipbuilding continued at Varna and Ruse. Ferrous metallurgy remains concentrated at Kremikovtsi and at Stomana in Pernik, with a third base at Debelt, while lead and zinc are refined at Plovdiv, Kardzhali and Novi Iskar, copper at Pirdop and aluminium at Shumen.

Mining contributed less than 2% of GDP and engaged under 3% of the workforce in the early 2000s, and the industries around it employ some 120,000 people. The Elatsite copper mine, built under the communist government, extracts 13 million tonnes of ore a year and yields about 42,000 tonnes of copper, 1.6 tonnes of gold and 5.5 tonnes of silver.

What the land produces

Agriculture accounts for less than a tenth of national income. Cereals occupy almost three fifths of the sown land, wheat ahead of maize and barley. Sunflower is the chief oilseed and grows with sugar beet in the north; tobacco of the Oriental type grows mainly in the south, and the state tobacco company Bulgartabac was sold to a Russian firm in 2011. In 2006 the wheat harvest came to 3.3 million tonnes, maize to 1.6 million and sunflower to 1.2 million. Forestry works nearly 4 million hectares, and in 2004 an estimated 45% of the timber harvest was cut illegally.

Tourism grew from 2.3 million foreign visitors in 2000 to 4 million in 2004 and about 10 million in 2016, on the Black Sea resorts, the winter centres at Bansko, Borovets and Pamporovo, and the monastery at Rila.

Where the electricity comes from

About half of Bulgaria's energy is imported, and coal and nuclear power together supply nearly nine tenths of its electricity. Geological survey has identified about 40 coal basins holding almost 3 billion tons of proven recoverable reserves, virtually all of it lignite. The Maritsa field feeds the large thermal stations at Dimitrovgrad and Maritsa-Iztok, with others at Pernik, Sofia, Plovdiv and Burgas. The Kozloduy nuclear station, built with Soviet assistance and running since 1974, supplied more than 40% of the country's electric power in 2005; two of its reactors were shut in 2002 and two more in 2006 as a condition of European Union accession.

Gas is the exposed part. Bulgaria relies on Russia for its natural gas, and when supplies were cut during the Russia and Ukraine dispute at the start of 2009 both industrial output and public services suffered. Domestic reserves are thin: proved natural gas reserves of 5.7 billion cubic metres and proved oil reserves of 15 million barrels as of 1 January 2006, against gas consumption of about 5.2 billion cubic metres in 2005.

Why imports keep running ahead of exports

Almost two thirds of Bulgarian exports are capital goods, machinery and equipment above all, and about a quarter are consumer goods of agricultural origin: fruit, wine, cigarettes, dairy products and meat. About two fifths of imports are capital goods, and a large part of the remainder is raw material, cloth, metal ore and petroleum, processed in the country and sent out again. The Soviet Union was the dominant partner until its dissolution; by 2004 European Union members took 58% of exports and supplied 54% of imports. Outside the Union the main export destinations are Turkey, China and Serbia, and the largest sources of imports are Russia, Turkey and China.

The balance has been negative for a long time. Exports were 11.7 billion dollars in 2005 against imports of 15.9 billion, a deficit of 4.2 billion, and the current account deficit reached 12.65 billion dollars in 2008. Preliminary figures from the National Statistical Institute put exports of goods at 61,998.1 million leva for January to September 2025, 4.8% below the same months of 2024, with imports at 75,601.7 million leva and a trade deficit of 13,603.6 million leva.

A country with a floating currency would expect a gap of that size to show up in the exchange rate. Bulgaria's rate does not move, so the adjustment lands somewhere else.

How the economy adjusts when the rate cannot

The account the Fund published on the arrangement in 1999 named the costs plainly. With a currency board in place the central bank can no longer act as a lender of last resort to banks in trouble, and adjustments of domestic interest or exchange rates cannot be used to stimulate the economy. Adjustment happens through wages and prices, which the Fund described as "both slower and more painful".

The recession that began in 2008 is the worked example. GDP fell by 5.5% in 2009 and grew by 0.2% in 2010, and output regained its pre-crisis level in 2014. The labour market took the strain that the exchange rate could not: unemployment stood at 19% in 2000, 16.9% at the end of 2002 and 11.5% in 2005, then fell to about 7% in late 2016 and to 3.5% in 2025.

Wages carry the other half of the adjustment. The average gross monthly salary was 2,468 leva, or 1,262 euro, in December 2024. The Economic Research Institute at the Bulgarian Academy of Sciences reports the Bulgarian average as a quarter of the European Union average, and argues that it would be twice as high if labour productivity were put into the formula. GDP per head was 20,328 dollars in 2025, and 44,451 dollars measured at purchasing power parity in the same year.

The third channel is the size of the workforce itself. Bulgaria has recorded negative population growth every year since 1989, when the post-Cold War collapse started an emigration wave, and between 937,000 and 1,200,000 people, most of them young adults, had left by 2005. The total fertility rate was 1.59 children per woman in 2024. The population was 6,423,207 on 31 December 2025 and fell by 0.1% over that year. Employment, wages and the number of people available to work are what move in Bulgaria when a currency cannot.

What changed when the euro arrived

The Bulgarian National Bank issued the lev from 1880 until 2026. Convergence reports published on 4 June 2025 concluded that the country met the criteria, the European Parliament endorsed entry on 8 July 2025, and the Council of the European Union adopted the final three legislative acts required. Prices were displayed in both currencies from 8 August 2025, euro cash reached commercial banks from 1 November 2025 and coin starter kits reached businesses and the public from 1 December. The euro entered circulation on 1 January 2026, lev bank accounts were converted automatically, and from 1 February 2026 euro banknotes and coins were the sole legal tender. Leva can be exchanged free of charge at commercial banks and certain post offices until 30 June 2026, and at the central bank without a time limit.

The conversion rate of 1.95583 leva to one euro was not a new number. The peg moved from the deutsche mark to the euro when the euro appeared, at a fixed rate, and the rate at which Bulgarian salaries, savings and contracts were redenominated in 2026 was the rate they had been held at ever since.

What changed is where the decision sits. From January 2026 interest rates in Bulgaria follow the decisions of the Governing Council of the European Central Bank, which weighs conditions across the euro area as a whole, and the Governor of the Bulgarian National Bank takes part in that Council as a full member. The arrangement of 1997 gave the country a rule it had no say in. The arrangement of 2026 gives it one seat at the table where the rule is now written.
