The EMS (European Monetary System) was initially conceived as a response to the end of the Bretton Woods System.
Over time, it evolved into a DM (Deutsche Mark) area effectively controlled by the Bundesbank (German central bank).
The influence of the Bundesbank and the speculative attack of 1993 made the monetary union option more appealing.
Currently, the EMS serves primarily as a pathway for countries seeking to join the monetary union.
Four Incarnations of the EMS
1979-82: EMS-1
Characterized by narrow bands of fluctuation (±2.25%).
Symmetric arrangement.
1982-93: EMS-1
Centered on the DM.
Avoided realignments.
1993-99: EMS-1
Featured wide bands (±15%).
1999- : EMS-2
Asymmetric.
Serves as a transition to the Euro area.
EMS-1: Key Features
Parity Grid:
Bilateral central parities.
Associated margins of fluctuations.
Mutual Unlimited Support:
Exchange market interventions.
Short-term loans.
Realignments:
Tolerated, if not encouraged.
Required unanimous agreement.
The E.C.U. (European Currency Unit):
Not a currency but a unit of account.
Gained some traction in private markets.
ECU Composition
The ECU was a basket of EU currencies, each with a specific amount and weight:
Belgian franc: 3.43100 (8.71%)
Danish krone: 0.19760 (2.71%)
Deutschemark: 0.62420 (32.68%)
Dutch guilder: 0.21980 (10.21%)
French franc: 1.33200 (20.79%)
Greek drachma: 1.44000 (0.49%)
Italian lira: 151.80000 (7.21%)
Irish punt: 0.00855 (1.08%)
Portuguese escudo: 1.39300 (0.71%)
Spanish peseta: 6.88500 (4.24%)
UK pound sterling: 0.08784 (11.17%)
EMS: Interpretation and Assessment
Improved upon the "Snake" arrangement to stabilize intra-European exchange rates through:
Mutual support mechanisms.
The unanimity rule for realignments.
Reflected the EU's egalitarian approach by:
Avoiding a central currency.
Implementing bilateral interventions by both strong and weak currency central banks.
Excluded the US dollar, emphasizing Europe's independence.
Raises the question of whether monetary policy independence is lost.
Highlights the Impossible trinity:
Widespread capital controls were used to maintain the ability to have different inflation rates.
Evolution: From Symmetry to DM Zone
Initially, a flexible arrangement:
Allowed for different inflation rates, providing long-run monetary policy independence.
Employed frequent realignments.
However, realignments:
Barely compensated for accumulated inflation differences.
Were easily anticipated by markets.
Put weak currency/high inflation countries in a difficult position due to:
Continuing current account deficits.
Speculative attacks.
The symmetry was broken in practice.
The Bundesbank became the de facto model to follow.
The DM Zone
Shadowing the Bundesbank required:
Giving up much of the remaining monetary policy independence.
Aiming for a low, German-style inflation rate.
Avoiding realignments to build credibility.
Breakdown of the DM Zone
Bad Design:
Full capital mobility established in 1990 as part of the Single Act created a contradiction with the impossible trinity unless all monetary independence was relinquished.
Bad Luck:
German unification was a major shock that necessitated a very tight monetary policy.
The Danish referendum on the Maastricht Treaty added to the instability.
A wave of speculative attacks in 1992-3 occurred because:
The Bundesbank set limits to unlimited support.
Contradictory Lessons From 1993
The two-corner view:
Argues that since even the cohesive EMS did not survive, countries should choose one of the two extreme corners.
The EMS should be made even more cohesive:
Suggests that monetary union is the necessary path forward.
The EMS was a bad idea:
Argues that floating exchange rates are the future.
Unlimited interventions cannot be unlimited:
Emphasizes the need for more discipline and less support.
Contradictory Lessons From 1993 Part 2
The Bundesbank’s selection of countries to be supported:
Left scars (e.g. Britain).
Raised questions about decision-making criteria.
Speculative attacks can impact even robust systems and properly valued currencies, suggesting self-fulfilling crises.
Both facts strengthen the two-corner view, providing arguments for each corner.
The Wide-Band EMS
Emerged as a way out of the crisis:
Featured wide bands of fluctuation (±15%).
Represented a soft EMS on the path to monetary union.
EMS-2
EMS-1 ceased to exist on January 1, 1999, with the launch of the Euro.
EMS-2 was created to:
Host currencies of existing EU members who cannot or do not want to join the Euro area:
Denmark and the UK have a derogation, but Denmark has adopted the new ERM.
Sweden has no derogation but has declined to adopt the new ERM.
Host currencies of new EU members before they are admitted into the Euro area:
Potentially ten new members.
A Revival of The EMS?
In principle, ERM (Exchange Rate Mechanism) membership is compulsory for all new EU members.
They must remain in the ERM for at least two years before joining the Euro area.
They must also eliminate all capital controls.
The impossible trinity implies that they will have to fully give up monetary policy.
The risk of self-fulfilling crises suggests that this may not be sufficient to avoid trouble.
