Currency
Regimes is nothing but the system adopted by any country to manage its currency
exchange rate. No single currency is regime is good for all countries, at all
time. Fixed vs. Floating is oversimplified dichotomy, there is in fact a
continuum of flexibility along which it is possible to place most currency
regimes.
Currency
Union / common currency system:
·
Currency Union means two or more nations sharing same
currency.
·
One of the main goal of currency union is to synchronize
and manage each county’s monetary policy.
·
It helps in reducing transaction cost in cross-border
trade
·
The theory of optimum currency region (OCR) published by
Mundell in 1961 describes which region should form currency union.
Example
include European Monetary Union (Euro).
Currency
Board:
·
Currency board is monetary authority which act as a
regulator of nation’s exchange rate and makes decision about valuation of
nation’s currency.
·
Three major elements of currency board are:
a) exchange
rate that is fixed to an anchor currency
b) Automatic
convertibility, that is right to exchange domestic currency at fixed rate
decided by currency board whenever desired
c) Long term
commitment to system
·
Currency board system can be credible only if central
bank holds sufficient official foreign exchange reserves to at least cover the
entire narrow money supply.
·
Economic credibility, low inflation and lower interest
rates are some advantages of this system.
·
Limitation of currency board system is it brings some
restrictions on the central banks role.
·
By using a currency board a country is no longer in
control of its monetary policy.
Example: Bulgaria in 1997 adopted currency board system
to successfully recover from banking crisis in the country.
Truly
fixed:
·
Fixed Exchange rate system is a system wherein the
central bank interferes with the exchange rates with a view to keep it fixed.
·
There is a necessity for the country to keep a lot of
foreign exchange reserves because whenever it makes use of these reserves to
keep the exchange rate fixed.
·
Since the exchange rates are fixed, a trader of this
country need not resort to hedging in order to protect itself from exchange
rate risks.
·
The importer and exporters of this country know that the
exchange rate is fixed so they don’t need to worry about it and can concentrate
on their business.
·
Since the exchange rate is fixed, there is no speculation
involved in it.
Adjustable
peg:
·
It’s a currency regime in which the authorities declare
the regime as a fixed currency regime but keep an option of adjustment if
considerable changes in the economic fundamentals.
·
Most countries declare their regime as fixed but
periodically undergo realignment to balance the economy.
·
Periodic adjustments are done to improve country’s
competitive advantage in export market.
·
Klein & Marion 1994 report that mean duration of pegs
among world economies is about 10 months.
·
When exchange rate has been fixed for several years it
generates sense of complacency about the currency risk leading to large,
unhedged currency positions that can greatly increase the cost of depreciation.
Example: Chinese Yuan
Crawling
peg:
·
A system of exchange rate adjustment in which a currency
with a fixed exchange rate is allowed to fluctuate within a band of rates.
·
The par value of the stated currency is also adjusted
frequently due to market factors such as inflation. This gradual shift of the
currency's par value is done as an alternative to a sudden and significant
devaluation of the currency.
·
This system helps in avoiding instability which may occur
due to discrete and infrequent adjustments
·
It also Minimizes the rate of uncertainty and volatility
since the fluctuation in the exchange rate is kept minimal
Example: In the 1990s, Mexico had fixed its peso with the
U.S. dollar. However, due to the significant inflation in Mexico, as compared
to the U.S., it was evident that the peso would need to be severely devalued.
Because a rapid devaluation would create instability, Mexico put into place a
crawling peg exchange rate adjustment system, and the peso was slowly devalued
toward a more appropriate exchange rate.
Basket
peg:
·
The exchange rate is fixe in terms of weighted basket of
currencies instead of any one major currency.
·
This approach makes sense for countries with trade
patterns that are highly diversified geographically.
·
In most countries which use this system keep weights
secrete and adjust the weights or levels whenever situation arises.
·
The benefits of this regime include stabilizing trade
balances, capital flows, and gross domestic product (GDP) for countries that
trade with diverse countries.
·
This currency regime suffers from the issues like
complexity, no transparency, and no verifiability.
Managed
float:
·
It is a system wherein the exchange rates fluctuate but
the central bank of the country attempts to influence the exchange rate by
buying and selling of currencies.
·
It is a hybrid of Fixed and Floating exchange rate
regimes.
·
Generally the central bank may set a range between which
it will not interfere with the exchange rates. Only if the exchange rates vary
beyond this range then the central bank responds to bring the value back within
the range.
·
In managed floating exchange regime, if a currency is
valued above its range, then the central bank will sell some of its currency
from the reserve so by increasing the supply of their currency in the foreign
market, the value of the currency will decrease.
·
In Managed floating regime, there is sterilized
intervention. Consider the case of India- suppose Rupee is appreciating, then
the central bank i.e. RBI would intervene in the market and buy USD from the
foreign exchange thus strengthening the dollar and weakening the rupee. This is
done mainly so that the exporter does not suffer loss because of the change in
the exchange rate. In doing this, RBI has increased the rupee supply leading to
inflation. In order to contain that, RBI will suck out the liquidity it infused
due to its dollar buying by issuing government bond, raising CRR, etc. This is
sterilized intervention by the RBI. It is observed in economies adopting
managed floating exchange rates
Free
Float:
·
Free Floating exchange rate regime is a system where the
central bank of the country does not interfere with the exchange rate and
allows the foreign exchange market to affect the exchange rates.
·
The supply and demand for the particular currency in the
foreign exchange market will decide the exchange rate.
·
In a floating regime, central banks are extremely
reluctant to interfere with the exchange rate unless and until it is absolutely
necessary.
·
The exchange rate will show a lot of short-run volatility
with ups and downs from day to day.
·
The free floating nature of the exchange rate acts as an
economic stabilizer in response to market forces. For example: Consider that
the currency of a country depreciates because their imports are more than their
exports. On account of the depreciating currency, the exports of this country
will become cheaper and import will become costlier. Since the exports have
become cheaper, the quantity demanded for exported products will increase. Also
due to costlier imports, the quantity of imported products demanded will
decrease.
·
The country requires lesser foreign exchange reserves as
compared to a country following fixed exchange rate system. It is mainly because
the central bank does not interfere with the foreign exchange rates using their
reserves.
·
The negative point for this kind of exchange rate system
is that the exporters and importers of the country need to indulge in hedging
in order to protect their investments from the changes in the foreign exchange
rates.
·
Floating rate systems will give rise to speculations. So
speculations will be an inherent part of the floating exchange rate systems.
Example: Germany, France and UK are some of the economies
following free floating exchange rate regime.
