Background
Unsterilized intervention refers to a specific type of activity undertaken by a country’s central bank in the foreign exchange market. Unlike sterilized interventions, which involve offsetting monetary transactions to negate any impact on the domestic money supply, unsterilized interventions directly affect the money supply.
Historical Context
Unsterilized interventions have been utilized by central banks worldwide, particularly during periods of significant currency volatility. Historical instances include major monetary realignments and financial crises such as the Plaza Accord of 1985 and the 1997 Asian Financial Crisis. These periods saw aggressive interventions to stabilize exchange rates without neutralizing the monetary effect domestically.
Definitions and Concepts
Unsterilized Intervention: Central bank activities in the foreign exchange market that impact the money supply. This typically involves buying or selling foreign currency reserves to influence exchange rates without offsetting monetary operations.
Major Analytical Frameworks
Classical Economics
In classical economics, which generally presupposes long-term neutrality of money, unsterilized interventions are viewed skeptically as they may induce short-term imbalances and misread market signals.
Neoclassical Economics
Neoclassical perspectives emphasize the efficiency of markets. Thus, unsterilized interventions are seen as distortive, often only justified under exceptional circumstances where market failure is evident.
Keynesian Economics
Keynesians might support unsterilized interventions as a proactive method to correct macroeconomic imbalances and foster full employment, acknowledging that exchange rate shifts directly intervene in aggregate demand.
Marxian Economics
From a Marxist viewpoint, such interventions could be interpreted as manipulative actions by capitalist states to protect domestic economic interests, away from benefiting the working class.
Institutional Economics
Institutional economists would study unsterilized interventions by focusing on the role of institutions, examining how and why central banks opt for such measures in contextually institutionalized monetary regimes.
Behavioral Economics
Behavioral economics may analyze how unsterilized interventions affect market participant psychology, potentially influencing trading behavior and expectations about future market conditions.
Post-Keynesian Economics
Post-Keynesians might advocate for unsterilized interventions as part of comprehensive monetary and fiscal stabilizations to tackle issues like exchange rate instability impacting economy-wide uncertainty.
Austrian Economics
Austrian economists tend to oppose unsterilized interventions, arguing that they introduce artificial signals and eventual cycles of boom and bust, due to their distortionary impact on natural interest and exchange rates.
Development Economics
In developing nations, unsterilized interventions can be pivotal. Development economists would argue these measures help stabilize nascent financial markets and curb speculative attacks that can wreak havoc on weaker economies.
Monetarism
Monetarists generally oppose unsterilized interventions, emphasizing money supply control. They argue these interventions disrupt the regulatory framework aimed to maintain inflation stability and long-term economic health.
Comparative Analysis
A comparative study might look at the effectiveness of unsterilized versus sterilized interventions, considering the trade-offs related to domestic money supply effects, and contrasting the impacts across developed versus developing economies.
Case Studies

- Asian Financial Crisis (1997): Central banks in Asia conducted unsterilized interventions to counteract currency devaluations and speculative attacks.
