The United Kingdom joined the European Exchange Rate Mechanism (ERM), committing to keep sterling within agreed limits against other European currencies. This policy aimed to reduce inflation by tying UK monetary policy more closely to low-inflation countries such as Germany. It also reduced room for the UK to cut interest rates during an economic slowdown.
European Community countries signed the Maastricht Treaty, a major step toward deeper economic and political union. It set out plans for Economic and Monetary Union and helped make exchange-rate stability a high political priority. In practice, the treaty increased pressure on governments to defend fixed exchange-rate commitments like the ERM.
Denmark voted against the Maastricht Treaty in a referendum. The result raised doubts about whether Europe’s monetary-union plans would move forward smoothly. That uncertainty contributed to market tension in a period when several currencies were already under pressure.
Italy devalued the lira within the ERM after severe market pressure, an early sign that the system’s fixed bands were becoming hard to defend. The move acknowledged that the lira’s existing rate was not credible under current conditions. It also increased attention on other currencies seen as vulnerable, including sterling.
After heavy speculative selling, the UK government suspended sterling’s ERM membership. During the crisis, the authorities raised the minimum lending rate to 12% and announced a plan to raise it to 15%, but the defense did not hold. The decision marked a major shift away from a fixed exchange-rate policy toward letting sterling move more freely.
Soon after the UK’s exit, Italy also stopped intervening to keep the lira inside its ERM range, effectively allowing it to float. This showed that defending fixed rates could become too costly when markets expected devaluation. The ERM crisis was no longer limited to one country; it was becoming a wider European currency storm.
Spain devalued the peseta by about 5% while remaining in the ERM. The goal was to restore competitiveness and reduce speculation by resetting the currency’s central rate. This was part of a pattern: some countries tried to preserve the system by adjusting pegs rather than abandoning them outright.
French voters approved the Maastricht Treaty by a very small margin. The close result showed how politically sensitive monetary integration had become. With public support uncertain, governments faced added difficulty in sustaining high-interest-rate defenses of currency pegs during recession.
Sweden’s central bank gave up defending a fixed exchange rate and allowed the krona to float after intense market pressure. Although Sweden was not an ERM member, the decision reflected the same dilemma seen across Europe: defending a peg could require extremely high interest rates and large interventions. The krona float added to the broader shift toward more flexible exchange rates in the region.
Ireland devalued the Irish pound (punt) by 10% to keep it within the ERM bands. The move aimed to protect competitiveness, especially given Ireland’s strong trade links with the UK, whose currency was now floating. It showed that some countries still preferred a managed exchange-rate system, even after repeated crises.
European finance ministers agreed to widen the allowed ERM trading ranges for most currencies to ±15% around central rates. This effectively reduced the need for constant intervention and made the system much closer to managed floating. The change helped calm speculation by making one-way bets against narrow pegs less attractive.
At the start of Stage Three of Economic and Monetary Union, ERM II replaced the earlier European Monetary System arrangements. ERM II was designed to link non-euro EU currencies to the new euro with a standard ±15% fluctuation band. This created a more flexible framework for exchange-rate stability after the lessons of the 1992–1993 crisis years.
