Danish krone and the
Bulgarian lev.
Intent and operation
The ERM is based on the concept of fixed currency exchange rate margins, but with exchange rates variable within those margins. This is also known as a semi-pegged system. Before the introduction of the euro, exchange rates were based on the
European Currency Unit (ECU), the European unit of account, whose value was determined as a weighted average of the participating currencies.
A grid (known as the Parity Grid) of bilateral rates was calculated on the basis of these central rates expressed in ECUs, and currency fluctuations had to be contained within a margin of 2.25% on either side of the bilateral rates (with the exception of the

Historical exchange-rate regimes for EU members
The chart below provides a full summary of all applying
exchange-rate regimes for
EU members, since the
European Monetary System with its Exchange Rate Mechanism and the related new common currency
ECU came into being on 13 March 1979. The euro replaced the ECU 1:1 at the exchange rate markets, on 1 January 1999. Between 1979 and 1999 the
D-Mark functioned as a ''de facto'' anchor for the ECU, meaning there was only a minor difference between pegging a currency against the ECU and pegging it against the D-Mark.

was established with its first 11 member states on 1 January 1999. The first
enlargement of the eurozone, to Greece, took place on 1 January 2001, one year before the euro had physically entered into circulation. The zone's next enlargements were with states that
joined the EU in 2004, and then joined the eurozone on 1 January in the mentioned year: Slovenia (2007), Cyprus (2008), Malta (2008), Slovakia (2009), Estonia (2011), Latvia (2014), Lithuania (2015). Croatia, which joined in the EU 2013, adopted the euro in 2023.

Forced withdrawal of the sterling
The United Kingdom entered the ERM in October 1990, but was forced to exit the programme within two years after sterling came under major pressure from currency speculators. The ensuing crash of 16 September 1992 was subsequently dubbed " Black Wednesday". There was some revision of attitude towards this event given the UK's strong economic performance after 1992, with some commentators dubbing it "White Wednesday".
Some commentators, following Norman Tebbit, took to referring to ERM as an "Eternal Recession Mechanism", after the UK fell into recession in 1990. The UK spent over £6 billion trying to keep the currency within the narrow limits with reports at the time widely noting that the controversial Hungarian-American investor George Soros's individual profit of £1 billion equated to over £12 for each man, woman and child in Britain and dubbing Soros "the man who broke the Bank of England".
Britain's membership of the ERM was also blamed for prolonging the recession at the time, and Britain's exit from the ERM was seen as an economic failure which contributed significantly to the defeat of the Conservative

On 31 December 1998, the European Currency Unit (ECU) exchange rates of the eurozone

countries were frozen and the value of the euro, which then superseded the ECU at par, was thus established.
In 1999, ERM II replaced the original ERM. The Greek and Danish currencies were part of the new mechanism, but when Greece joined the euro in 2001, the Danish krone was left at that time as the only participant member. A currency in ERM II is allowed to float within a range of ±15% with respect to a central rate against the euro. In the case of the krone, Danmarks Nationalbank

Sweden has voted in a referendum to stay out of the mechanism, despite being expected to join by the ECB, since Sweden has no opt-out like Denmark. EU members are required to join the ERM by the Maastricht convergence criteria.
Exchange rate bands
In theory, most of the currencies are allowed to fluctuate as much as 15% from their assigned value. In practice, however, the currency of Denmark deviates very little.
