An unsterilized foreign exchange intervention refers to actions taken by a country’s central bank to influence its currency’s exchange rate without taking offsetting measures to neutralize the impact on the domestic money supply. This type of intervention directly alters the amount of money circulating in the economy, thereby impacting liquidity and interest rates.
Mechanisms of Unsterilized Intervention
Unsterilized interventions involve the purchase or sale of foreign currencies by the central bank. When a central bank buys foreign currency, it pays for these purchases with its own currency, which increases the domestic money supply. Conversely, selling foreign currency reduces the domestic money supply because the central bank withdraws its currency from the market in exchange for the foreign currency.
Implications for Exchange Rates and Money Supply
-
- Depreciation: Buying foreign currency increases the demand for that currency, leading to a depreciation of the central bank’s own currency.
- Appreciation: Selling foreign currency increases the supply of that foreign currency, leading to an appreciation of the central bank’s own currency.
-
- Increase in Money Supply: Buying foreign currency injects more of the domestic currency into the economy.
- Decrease in Money Supply: Selling foreign currency withdraws domestic currency from circulation.
Historical Context and Examples
Historically, unsterilized interventions have been used by various countries to manage their currency values relative to others, particularly during times of economic instability or to correct imbalances.
Example: 1997 Asian Financial Crisis
During the 1997 Asian Financial Crisis, several Asian countries employed unsterilized interventions in a bid to stabilize their currencies against rapid depreciation.
Practical Applications in Economic Policy
Unsterilized interventions are often part of broader monetary policy strategies. While they can offer quick impacts on currency value and monetary conditions, they also come with risks such as inflation or deflation due to significant changes in money supply.
Comparison with Sterilized Interventions
Sterilized Interventions
- Definition: Central bank actions that offset the impact on the domestic money supply, typically through open market operations.
- Use Case: Sterilized interventions aim to influence exchange rates without altering the domestic money supply.
| Aspect | Unsterilized Intervention | Sterilized Intervention |
|---|---|---|
| Impact on Money Supply | Direct | Neutralized |
| Tools Used | Foreign currency trade | Foreign currency trade and open market operations |
| Typical Consequences | Changes in liquidity, interest rates | Focused on exchange rates only |

FAQs
Q1: Why do central banks use unsterilized interventions? A: To quickly influence exchange rates and subsequently affect the domestic economy’s liquidity and monetary conditions.
Q2: What are the risks associated with unsterilized interventions? A: They can cause inflation or deflation by significantly altering the money supply.
Q3: How do unsterilized interventions differ from sterilized ones? A: Unsterilized interventions directly impact the money supply, whereas sterilized interventions include counteracting measures to keep the money supply stable.

By directly impacting the money supply, they offer a means to quickly address economic imbalances, though they come with inherent risks that must be carefully managed.
