There is a great deal of academic theory revolving around currencies.
While often not applicable directly to day-to-day trading, it is helpful
to understand the overarching ideas behind the academic research.
The main economic theories found in the foreign exchange deal with parity conditions. A parity
condition is an economic explanation of the price at which two
currencies should be exchanged, based on factors such as inflation and
interest rates. The economic theories suggest that when the parity
condition does not hold, an arbitrage opportunity exists for market
participants. However, arbitrage opportunities, as in many other
markets, are quickly discovered and eliminated before even giving the
individual investor an opportunity to capitalize on them. Other theories
are based on economic factors such as trade, capital flows and the way a
country runs its operations. We review each of them briefly below.
Major Theories: Purchasing Power Parity
Purchasing Power Parity
(PPP) is the economic theory that price levels between two countries
should be equivalent to one another after exchange-rate adjustment. The
basis of this theory is the law of one price, where the cost of an
identical good should be the same around the world. Based on the theory,
if there is a large difference in price between two countries for the
same product after exchange rate adjustment, an arbitrage opportunity is
created, because the product can be obtained from the country that
sells it for the lowest price.
The relative version of PPP is as follows:
 |
Where 'e' represents the rate of change in the exchange rate and 'π1' and 'π2'represent the rates of inflation for country 1 and country 2, respectively.
For
example, if the inflation rate for country XYZ is 10% and the inflation
for country ABC is 5%, then ABC's currency should appreciate 4.76%
against that of XYZ.
 |
Interest Rate Parity
The concept of Interest Rate Parity
(IRP) is similar to PPP, in that it suggests that for there to be no
arbitrage opportunities, two assets in two different countries should
have similar interest rates, as long as the risk for each is the same.
The basis for this parity is also the law of one price, in that the
purchase of one investment asset in one country should yield the same
return as the exact same asset in another country; otherwise exchange
rates would have to adjust to make up for the difference.
The formula for determining IRP can be found by:
 |
Where 'F' represents the forward exchange rate; 'S' represents the spot exchange rate; 'i1' represents the interest rate in country 1; and 'i2' represents the interest rate in country 2.
International Fisher Effect
The International Fisher Effect (IFE )
theory suggests that the exchange rate between two countries should
change by an amount similar to the difference between their nominal
interest rates. If the nominal rate in one country is lower than
another, the currency of the country with the lower nominal rate should
appreciate against the higher rate country by the same amount.
The formula for IFE is as follows:
 |
Where 'e' represents the rate of change in the exchange rate and 'i1' and 'i2'represent the rates of inflation for country 1 and country 2, respectively.
Balance of Payments Theory
A country's balance of payments is comprised of two segments - the current account and the capital account
- which measure the inflows and outflows of goods and capital for a
country. The balance of payments theory looks at the current account,
which is the account dealing with trade of tangible goods, to get an
idea of exchange-rate directions.
If a country is running a large current account surplus or deficit,
it is a sign that a country's exchange rate is out of equilibrium. To
bring the current account back into equilibrium, the exchange rate will
need to adjust over time. If a country is running a large deficit (more
imports than exports), the domestic currency will depreciate. On the
other hand, a surplus would lead to currency appreciation.
The balance of payments identity is found by:

The main economic theories found within the interchange take care of parity conditions. A parity condition is AN economic rationalization of the value at that 2 currencies ought to be changed, supported factors like inflation and interest rates. The economic theories counsel that once the parity condition doesn't hold, AN arbitrage chance exists for market participants. However, arbitrage opportunities, as in several different markets, ar quickly discovered and eliminated before even giving the individual capitalist a chance to maximize them. different theories ar supported economic factors like trade, capital flows and also the manner a rustic runs its operations. we have a tendency to review every of them shortly below. Major Theories: getting Power Parity Purchasing Power Parity (PPP) is that the theory that worth levels between 2 countries ought to be akin to each other when exchange-rate adjustment. the premise of this theory is that the law of 1 worth, wherever the price of a regular smart ought to be identical round the world. supported the speculation, if there's an outsized distinction in worth between 2 countries for identical product when rate adjustment, AN arbitrage chance is formed, as a result of the merchandise will be obtained from the country that sells it for the bottom worth. The relative version of surgery is as follows: Where 'e' represents the speed of amendment within the rate and 'π1' and 'π2'represent the rates of inflation for country one and country two, severally. For example, if the rate of inflation for country XYZ is 100 percent and also the inflation for country fundamental principle is five-hitter, then basics currency ought to appreciate four.76% against that of XYZ. Interest Rate Parity The conception of rate of interest Parity (IRP) is comparable to surgery, in this it suggests that for there to be no arbitrage opportunities, 2 assets in 2 totally different countries ought to have similar interest rates, as long because the risk for every is that the same. the premise for this parity is additionally the law of 1 worth, in this the acquisition of 1 investment quality in one country ought to yield identical come back because the very same quality in another country; otherwise exchange rates would got to comply with form up for the distinction. The formula for determinative IRP will be found by: Where 'F' represents the forward exchange rate; 'S' represents the spot exchange rate; 'i1' represents the rate of interest in country 1; and 'i2' represents the rate of interest in country two. International Fisher result The International Fisher result (IFE) theory suggests that the rate between 2 countries ought to amendment by AN quantity just like the distinction between their nominal interest rates. If the nominal rate in one country is less than another, the currency of the country with the lower nominal rate ought to appreciate against the upper rate country by identical quantity. The formula for IFE is as follows: Where 'e' represents the speed of amendment within the rate and 'i1' and 'i2'represent the rates of inflation for country one and country two, severally. Balance of Payments Theory A country's balance of payments is comprised of 2 segments - this account and also the capital account - that live the inflows and outflows of products and capital for a rustic. The balance of payments theory appearance at this account, that is that the account managing trade of tangible merchandise, to urge a concept of exchange-rate directions. If a rustic is running an outsized accounting surplus or deficit, it's an indication that a country's rate is out of equilibrium. To bring this account back to equilibrium, the rate can ought to change over time. If a rustic is running an outsized deficit (more imports than exports), the domestic currency can depreciate. On the opposite hand, a surplus would result in currency appreciation. The balance of payments identity is found by: Where BCA represents this account balance; BKA represents the capital account balance; and bandeau represents the reserves account balance. Real rate of interest Differentiation Model The Real rate of interest Differential Model merely suggests that countries with higher real interest rates can see their currencies appreciate against countries with lower interest rates. the explanation for this is often that investors round the world can move their cash to countries with higher real rates to earn higher returns, that bids up the value of the upper real rate currency. Asset Market Model The quality Market Model appearance at the influx of cash into a rustic by foreign investors for the aim of buying assets like stocks, bonds and different money instruments. If a country is seeing massive inflows by foreign investors, the worth of its currency is expected to increase, because the domestic currency has to be purchased by these foreign investors. This theory considers the capital account of the balance of trade compared to this account within the previous theory. This model has gained additional acceptance because the capital accounts of states ar beginning to greatly surmount this account as international cash flow will increase. Monetary Model The financial Model focuses on a country's financial policy to assist confirm the rate. A country's financial policy deals with the money offer of that country, that is decided by each the rate of interest set by central banks and also the quantity of cash written by the treasury. Countries that adopt a financial policy that chop-chop grows its financial offer can see inflationary pressure because of the exaggerated quantity of cash in circulation. This ends up in a devaluation of the currency. These economic theories, that ar supported assumptions and excellent things, facilitate let's say the fundamental fundamentals of currencies and the way they're wedged by economic factors. However, the actual fact that there ar numerous conflicting theories indicates the problem in anyone of them being 100 percent correct in predicting currency fluctuations. Their importance can probably vary by the various market atmosphere, however it's still necessary to grasp the basic basis behind every of the theories. Economic information Economic theories could move currencies within the long run, however on a shorter-term, every day or week-to-week basis, economic information includes a additional vital impact. it's usually same the most important corporations within the world are literally countries which their currency is basically shares in this country. Economic information, like the most recent gross domestic product (GDP) numbers, ar usually thought of to be sort of a company's latest earnings information. within the same manner that money news and current events will have an effect on a company's stock worth, news and knowledge a few country will have a serious impact on the direction of that country's currency. Changes in interest rates, inflation, state, client confidence, GDP, political stability etc. will all result in extraordinarily massive gains/losses counting on the character of the announcement and also the current state of the country. The number of economic announcements created day by day from round the world will be daunting, however joined spends longer learning concerning the forex put up for sale becomes clear that announcements have the best influence. Listed below ar variety of economic indicators that ar typically thought of to possess the best influence - despite that country the announcement comes from. Employment information Most countries unleash information concerning the amount of individuals that presently ar utilized at intervals that economy. In the U.S., this information is understood as non-farm payrolls and is discharged the primary Friday of the month by the Bureau of Labor Statistics. In most cases, robust will increase in a job signal that a rustic enjoys a prosperous economy, whereas decreases ar an indication of potential contraction. If a rustic has gone recently through economic troubles, robust employment information might send the currency higher as a result of it's an indication of economic health and recovery. On the opposite hand, high employment may also result in inflation, therefore this information might send the currency downward. In different words, economic information and also the movement of currency can usually depend upon the circumstances that exist once the information is discharged. Interest Rates As was seen with a number of the economic theories, interest rates ar a serious focus within the forex market. the foremost focus by market participants, in terms of interest rates, is placed on the country's financial institution changes of its discount, that is employed to regulate financial offer and institute the country's financial policy. In the U.S., the Federal Open Market Committee (FOMC) determines the discount, or the speed at that business banks will borrow and lend to the U.S. Treasury. The FOMC meets eight times a year to form choices on whether or not to boost, lower or leave the discount the same; and every meeting, beside the minutes, could be a purpose of focus. (For additional on central banks browse Get to grasp the most important Central Banks.) Inflation Inflation information measures the will increase and reduces of worth levels over a amount of your time. because of the sheer quantity of products ANd services at intervals an economy, a basket of products and services is employed to live changes in costs. worth will increase ar an indication of inflation, that suggests that the country can see its currency depreciate. In the U.S., inflation information is shown within the client indicator, that is discharged on a monthly basis by the Bureau of Labor Statistics. Gross Domestic Product The gross domestic product of a rustic could be a live of all of the finished merchandise and services that a rustic generated throughout a given amount. The value calculation is split into four categories: personal consumption, government payment, business payment and total internet exports. value is taken into account the most effective overall live of the health of a country's economy, with value will increase sign economic process. The healthier a country's economy is, the additional enticing it's to foreign investors, that successively will usually result in will increase within the worth of its currency, as cash moves into the country. In the U.S., this information is discharged by the Bureau of Economic Analysis once a month within the third or fourth quarter of the month. Retail Sales Retail sales information measures the quantity of sales that retailers create throughout the amount, reflective client payment. The live itself does not check up on all stores, but, just like value, uses a gaggle of stores of varied sorts to urge a concept of client payment. This live additionally provides market participants a concept of the strength of the economy, wherever exaggerated payment signals a robust economy. In the U.S., the Department of Commerce releases information on retail sales round the middle of the month. Durable Goods The data for {durable merchandise|durables|consumer durables|consumer goods} (those with a period of quite 3 years) measures the quantity of factory-made goods that ar ordered, shipped and empty for the fundamental quantity. These merchandise embody such things as cars and appliances, giving economists a concept of the quantity of individual payment on these longer-term merchandise, beside a concept of the health of the mill sector. This live once more provides market participants insight into the health of the economy, with information being discharged round the twenty sixth of the month by the Department of Commerce. Trade and Capital Flows Interactions between countries produce Brobdingnagian financial flows which will have a considerable impact on the worth of currencies. As was mentioned before, a rustic that imports way more than it exports might see its currency decline because of its ought to sell its own currency to get the currency of the commerce nation. moreover, exaggerated investments in an exceedingly country will result in substantial will increase within the worth of its currency. Trade flow information appearance at the distinction between a country's imports and exports, with a deficit occurring once imports ar bigger than exports. In the U.S., the Commerce releases balance of trade information on a monthly basis, that shows the quantity of products and services that the U.S. exported and foreign throughout the past month. Capital flow information appearance at the distinction within the quantity of currency being brought in through investment and/or exports to currency being sold for foreign investments and/or imports. a rustic that's seeing lots of foreign investment, wherever outsiders ar getting domestic assets like stocks or property, can typically have a capital flow surplus. Balance of payments information is that the combined total of a country's trade and capital flow over a amount of your time. The balance of payments is split into 3 categories: this account, the capital account and also the money account. The current account appearance at the flow of merchandise and services between countries. The capital account appearance at the exchange of cash between countries for the aim of buying capital assets. The financial account looks at the monetary flow between countries for investment purposes. Macroeconomic and political science Events The biggest changes within the forex usually come back from economics and political science events like wars, elections, financial policy changes and money crises. These events have the flexibility to alter or reshape the country, together with its fundamentals. as an example, wars can put a large economic strain on a rustic and greatly increase the volatility in an exceedingly region, that might impact the worth of its currency. it's necessary to stay up up to now on these economics and political science events. There is such a lot information that's discharged within the forex market that it will be terribly tough for the typical individual to grasp that information to follow. Despite this, it's necessary to grasp what news releases can have an effect on the currencies you trade.

capital account balance; and BRA represents the reserves account
balance.
Real Interest Rate Differentiation Model
The Real Interest Rate
Differential Model simply suggests that countries with higher real
interest rates will see their currencies appreciate against countries
with lower interest rates. The reason for this is that investors around
the world will move their money to countries with higher real rates to
earn higher returns, which bids up the price of the higher real rate
currency.
Asset Market Model
The Asset
Market Model looks at the inflow of money into a country by foreign
investors for the purpose of purchasing assets such as stocks, bonds and
other financial instruments. If a country is seeing large inflows by
foreign investors, the price of its currency is expected to increase, as
the domestic currency needs to be purchased by these foreign investors.
This theory considers the capital account of the balance of trade
compared to the current account in the prior theory. This model has
gained more acceptance as the capital accounts of countries are starting
to greatly outpace the current account as international money flow
increases.
Monetary Model
The Monetary
Model focuses on a country's monetary policy to help determine the
exchange rate. A country's monetary policy deals with the money supply
of that country, which is determined by both the interest rate set by
central banks and the amount of money printed by the treasury. Countries
that adopt a monetary policy that rapidly grows its monetary supply
will see inflationary pressure due to the increased amount of money in
circulation. This leads to a devaluation of the currency.
These
economic theories, which are based on assumptions and perfect
situations, help to illustrate the basic fundamentals of currencies and
how they are impacted by economic factors. However, the fact that there
are so many conflicting theories indicates the difficulty in any one of
them being 100% accurate in predicting currency fluctuations. Their
importance will likely vary by the different market environment, but it
is still important to know the fundamental basis behind each of the
theories.
Economic Data
Economic theories
may move currencies in the long term, but on a shorter-term, day-to-day
or week-to-week basis, economic data has a more significant impact. It
is often said the biggest companies in the world are actually countries
and that their currency is essentially shares in that country. Economic
data, such as the latest gross domestic product (GDP) numbers, are often
considered to be like a company's latest earnings data. In the same way
that financial news and current events can affect a company's stock
price, news and information about a country can have a major impact on
the direction of that country's currency. Changes in interest rates,
inflation, unemployment, consumer confidence, GDP, political stability
etc. can all lead to extremely large gains/losses depending on the
nature of the announcement and the current state of the country.
The
number of economic announcements made each day from around the world
can be intimidating, but as one spends more time learning about the
forex market it becomes clear which announcements have the greatest
influence. Listed below are a number of economic indicators that are
generally considered to have the greatest influence - regardless of
which country the announcement comes from.
Employment Data
Most countries release data about the number of people that currently are employed within that economy. In the U.S. ,
this data is known as non-farm payrolls and is released the first
Friday of the month by the Bureau of Labor Statistics. In most cases,
strong increases in employment signal that a country enjoys a prosperous
economy, while decreases are a sign of potential contraction. If a
country has gone recently through economic troubles, strong employment
data could send the currency higher because it is a sign of economic
health and recovery. On the other hand, high employment can also lead to
inflation, so this data could send the currency downward. In other
words, economic data and the movement of currency will often depend on
the circumstances that exist when the data is released.
Interest Rates
As
was seen with some of the economic theories, interest rates are a major
focus in the forex market. The most focus by market participants, in
terms of interest rates, is placed on the country's central bank changes
of its bank rate, which is used to adjust monetary supply and institute
the country's monetary policy. In the U.S. ,
the Federal Open Market Committee (FOMC) determines the bank rate, or
the rate at which commercial banks can borrow and lend to the U.S.
Treasury. The FOMC meets eight times a year to make decisions on whether
to raise, lower or leave the bank rate the same; and each meeting,
along with the minutes, is a point of focus. (For more on central banks
read Get to Know the Major Central Banks.)
Inflation
Inflation
data measures the increases and decreases of price levels over a period
of time. Due to the sheer amount of goods and services within an
economy, a basket of goods and services is used to measure changes in
prices. Price increases are a sign of inflation, which suggests that the
country will see its currency depreciate. In the U.S. , inflation data is shown in the Consumer Price Index, which is released on a monthly basis by the Bureau of Labor Statistics.
Gross Domestic Product
The
gross domestic product of a country is a measure of all of the finished
goods and services that a country generated during a given period. The
GDP calculation is split into four categories: private consumption,
government spending, business spending and total net exports. GDP is
considered the best overall measure of the health of a country's
economy, with GDP increases signaling economic growth. The healthier a
country's economy is, the more attractive it is to foreign investors,
which in turn can often lead to increases in the value of its currency,
as money moves into the country. In the U.S. , this data is released by the Bureau of Economic Analysis once a month in the third or fourth quarter of the month.
Retail Sales
Retail
sales data measures the amount of sales that retailers make during the
period, reflecting consumer spending. The measure itself doesn't look at
all stores, but, similar to GDP, uses a group of stores of varying
types to get an idea of consumer spending. This measure also gives
market participants an idea of the strength of the economy, where
increased spending signals a strong economy. In the U.S. , the Department of Commerce releases data on retail sales around the middle of the month.
Durable Goods
The
data for durable goods (those with a lifespan of more than three years)
measures the amount of manufactured goods that are ordered, shipped and
unfilled for the time period. These goods include such things as cars
and appliances, giving economists an idea of the amount of individual
spending on these longer-term goods, along with an idea of the health of
the factory sector. This measure again gives market participants
insight into the health of the economy, with data being released around
the 26th of the month by the Department of Commerce.
Trade and Capital Flows
Interactions
between countries create huge monetary flows that can have a
substantial impact on the value of currencies. As was mentioned before, a
country that imports far more than it exports could see its currency
decline due to its need to sell its own currency to purchase the
currency of the exporting nation. Furthermore, increased investments in a
country can lead to substantial increases in the value of its currency.
Trade flow data looks at the difference between a country's
imports and exports, with a trade deficit occurring when imports are
greater than exports. In the U.S. ,
the Commerce Department releases balance of trade data on a monthly
basis, which shows the amount of goods and services that the U.S.
exported and imported during the past month. Capital flow data looks at
the difference in the amount of currency being brought in through
investment and/or exports to currency being sold for foreign investments
and/or imports. A country that is seeing a lot of foreign investment,
where outsiders are purchasing domestic assets such as stocks or real
estate, will generally have a capital flow surplus.
Balance of
payments data is the combined total of a country's trade and capital
flow over a period of time. The balance of payments is split into three
categories: the current account, the capital account and the financial
account. The current account looks at the flow of goods and services
between countries. The capital account looks at the exchange of money
between countries for the purpose of purchasing capital assets. The
financial account looks at the monetary flow between countries for
investment purposes.
Macroeconomic and Geopolitical Events
The
biggest changes in the forex often come from macroeconomic and
geopolitical events such as wars, elections, monetary policy changes and
financial crises. These events have the ability to change or reshape
the country, including its fundamentals. For example, wars can put a
huge economic strain on a country and greatly increase the volatility in
a region, which could impact the value of its currency. It is important
to keep up to date on these macroeconomic and geopolitical events.
There
is so much data that is released in the forex market that it can be
very difficult for the average individual to know which data to follow.
Despite this, it is important to know what news releases will affect the
currencies you trade. (For more insight, check out Trading On News Releases and Economic Indicators To Know.)
Now
that you know a little more about what drives the market, we will look
next at the two main trading strategies used by traders in the forex
market – fundamental and technical analysis.
