Clean float and dirty float are terms used to describe
different exchange rate regimes and practices related to currency valuation and
management. Here’s an explanation of each:
Clean Float: Clean Float, also known as a freely floating
exchange rate refers to a situation where the exchange rate is determined purely
by market forces of supply and demand without any intervention or control by government
or central bank. Under a clean float system, the exchange rate fluctuates
freely in response to economic factors such as inflation, interest rates, trade
balances, capital flows, and market speculation. The government or central bank
does not actively intervene in the foreign exchange market to influence the
exchange rate. The exchange rate is solely determined by the interactions of
buyers and sellers in the market.
Advantages of clean float:
·
Reflects market
forces and economic fundamentals.
·
Allows for
automatic adjustments to change in supply and demand.
·
Reduce the need
for frequent intervention by the central bank.
·
Enhances market
efficiency and transparency.
Disadvantages of clean float
·
Exchange rate
volatility can create uncertainty for business and investors.
·
May lead to
speculative movements and sudden exchange rate fluctuations.
·
Can affect import/export
competitiveness due to unpredictable exchange rate movements.
Dirty Float: Dirty float, also known as a managed float or a
floating exchange rate with intervention, is a system where the exchange rate
is predominantly determined by market forces but with occasional intervention
by the government or central bank may intervene in the foreign exchange market by
buying or selling its currency to stabilize or manage the exchange rate within
a certain range or to address specific economic objectives.
Intervention in the foreign exchange market can be
done through various measures:
Direct intervention: The central bank actively buys
or sells its currency in the foreign exchange market to influence the exchange
rate.
Indirect intervention: The central bank may
implement policies such as interest rate adjustments, capital controls, or
reserve requirements to influence capital flows and indirectly impact the
exchange rate.
Advantages of dirty float:
·
Allows some
level of exchange rate stability and control
·
Provides a
buffer against excessive exchange rate volatility
·
Can help manage
external shocks and maintain competitiveness
·
Supports
specific economic objectives, such as controlling inflation or promoting
exports.
Disadvantages of dirty float:
·
Government or central
bank intervention can create moral hazard and distort market signal
·
The timing and effectiveness
of interventions can be challenging to determine.
·
Intervention may
deplete foreign exchange reserves if not managed prudently
·
Can lead to
conflicts or disputes with trading partners if perceived as currency
manipulation
It is important to note that the distinction between
clean float and dirty float is not always clear-cut as exchange rate regimes
can lie on a spectrum between fully fixed and fully floating. Some countries
may also adopt hybrid systems or make occasional interventions even within a
clean float framework, depending on their specific economic circumstances and
policy objectives.

Definition
|
Clean float refers to a system where the exchange
rate is purely determined by market forces without any intervention or interference
from the central bank or government
|
Dirty float refers to a system where the exchange
rate is allowed to fluctuate but may be subject to occasional intervention or
management by the central bank or government
|
Central Bank Intervention
|
No direct intervention or management by the
central bank or government in the foreign exchange market
|
Central Bank may occasionally intervene in the foreign
exchange market to stabilize or influence the exchange rate
|
Exchange Rate stability
|
Exchange rates are subject to market forces,
leading to potentially higher volatility and fluctuations
|
Exchange rates may be influenced or stabilized by
occasional central bank intervention, resulting in relatively more stable
exchange rate
|
Market Forces
|
Market forces of supply and demand primarily
determine the exchange rate
|
Market forces still play a role in determining the
exchange rate, but occasional central bank interventions may influence it
|
Flexibility
|
Exchange rate movements are flexible and respond
solely to market dynamics
|
Exchange rates may be subject to occasional
adjustments or management by the central bank or government for policy
reasons
|
Transparency
|
The exchange rate determination is transparent and
based on market mechanisms
|
The exchange rate determination may be less
transparent as the central bank’s occasional interventions may not be
disclosed
|
Exchange Rate Stability and Predictability
|
Exchange rate may experience higher volatility and
wider fluctuations, making it harder to predict future rates
|
Exchange rates may experience relatively more
stability and predictability due to occasional central bank interventions
|
Government Influence
|
The government does not directly influence or
manage the exchange rate
|
The government or central bank may have some
influence or control over the exchange rate through occasional interventions.
