EMS Notes

The EMS: Past and Present

  • 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.
