National central bank (Eurosystem) in the context of Bank of Greece

The Central Bank of Ireland (Irish: Banc Ceannais na hÉireann) is the national central bank for Ireland within the Eurosystem. It was the Irish central bank from 1943 to 1998, issuing the Irish pound. It is also the country's dominant financial supervisory authority.

The Central Bank of Ireland was founded on 1 February 1943, succeeding the Currency Commission of Ireland, a currency board established in 1922. Since 1 January 1972, it has operated under the Central Bank Act 1971, which completed the transition from the strict post-independence currency peg to the pound sterling to a fully autonomous central bank.

The National Bank of Belgium (NBB; Dutch: Nationale Bank van België, NBB; French: Banque nationale de Belgique, BNB; German: Belgische Nationalbank, BNB) is the national central bank for Belgium within the Eurosystem. It was the Belgian central bank from 1850 until 1998, established by law of 5 May 1850 and issuing the Belgian franc.

The Belgian government has held half of the National Bank's equity since the aftermath of World War II. It thus remains one of relatively few central banks whose equity capital is partly in private hands, with stock being traded on Euronext Brussels.

The Bulgarian National Bank (Bulgarian: Българска народна банка, romanized: Bulgarska narodna banka, IPA: [ˈbɤɫɡɐrskɐ nɐˈrɔdnɐ ˈbaŋkɐ], BNB) is the central bank of the Republic of Bulgaria, issuing the lev. On 1 January 2026, it is set to become the national central bank for Bulgaria within the Eurosystem as the country adopts the euro as its currency.

Headquartered in Sofia, the bank was established in 1879. It is the 13th-oldest continuously existing central bank in the world. The bank has a key role in the Bulgarian economy. An independent institution responsible for issuing all banknotes and coins in the country, BNB is tasked with safekeeping the government's currency reserves. It is also the sole owner of the Bulgarian Mint.
