Snake in the Tunnel

An agreement by a group of countries to closely manage exchange rates within a flexible rate system.

Background

The “snake in the tunnel” concept emerged in the early 1970s as a strategy for maintaining stability among European currencies. During this period, global exchange rate turbulence necessitated measures to manage currency fluctuations tightly.

Historical Context

Prior to the establishment of the European Monetary System (EMS) in 1979, European nations faced significant challenges in maintaining currency stability within a broader context of global exchange rate fluctuation. The “snake in the tunnel” was a precursor arrangement aimed at providing a controlled environment for inter-European currency stability after the collapse of the Bretton Woods system.

Definitions and Concepts

The “snake in the tunnel” refers to a two-tiered mechanism for exchange rate stabilization among a set of European currencies:

  • Tunnel: Represents the general accepted margin of fluctuations in exchange rates beyond which intervention is necessary.
  • Snake: Represents a narrower band within which the designated group of currencies aims to operate. This band lies within the broader tunnel and requires closer cooperation among member countries.

Major Analytical Frameworks

Classical Economics

Classical economics primarily focuses on long-run adjustments in the economy. The focused intervention mechanism in the “snake in the tunnel” would be seen as temporary and outside the natural adjustment processes.

Neoclassical Economics

Neoclassical thought emphasizes market mechanisms for determining exchange rates. The “snake in the tunnel” represents a managed approach that departs from pure market forces to ensure currency stability.

Keynesian Economics

From a Keynesian perspective, active government intervention is essential for economic stability. The conceptualization of the “snake in the tunnel” aligns with Keynesian advocacy for intervention to mitigate economic volatility.

Marxian Economics

Marxian critique might focus on the role such arrangements play within a capitalist framework, emphasizing how currency stability engagements serve the interests of dominant capitalist economies.

Institutional Economics

Institutional economists might examine the “snake in the tunnel” framework in terms of the formal mechanisms and informal conventions that govern international currency agreements.

Behavioral Economics

Behavioral economic analysis could explore how the structured frameworks of currency stability influence the behavior of market participants, including expectations and speculative actions.

Post-Keynesian Economics

Post-Keynesians might support the “snake in the tunnel” as a necessary measure for managing economic instability and promoting collective governance within the financial system.

Austrian Economics

Austrian economics tends to favor less government intervention and might critique the “snake in the tunnel” as an overreach that distorts natural market signals.

Development Economics

Development economists might examine how stable currency arrangements affect developmental outcomes, particularly in promoting stable trade environments for developing economies.

Monetarism

Monetarists, who emphasize the role of monetary policy, may view the “snake in the tunnel” critically, arguing that rather than stabilizing currencies through coordinated interventions, focus should remain on controlling money supply principles.

Comparative Analysis

In comparison to other exchange rate systems, such as a free float, the “snake in the tunnel” requires significant coordination among participant countries to manage country-specific and cooperative economic policies. This type of strategic intervention can significantly reduce exchange rate volatility but does present its own challenges regarding sovereignty and policy alignment among participating nations.
