The main difference is that international transactions involve the domestic currencies of at least two different countries. This means that individuals and firms engaging in international transactions need to exchange currencies to purchase goods, services, and assets in another country. For example, a Turkish firm importing Japanese goods would first need to exchange Turkish lira for Japanese yen.

The foreign exchange (forex) market is the world's oldest, largest, and most developed financial market. It is where the purchase and sale of foreign currencies occur, with participants worldwide conducting transactions every business day and hour.

The foreign exchange market is a market where international currency trade takes place, involving the conversion of one country's currency into another country's currency. Its primary function is to facilitate the exchange of currencies to enable international trade, investment, or financial funds transfer.

Individuals, corporations, exporters, importers, foreign investors, multinational companies, and tourists are among the participants. They engage in currency exchange to facilitate their international transactions. Banks are crucial players, facilitating most international transactions through foreign exchange transfers, deposits, loans, and letters of credit. They also conduct interbank trading in the wholesale market. Non-bank financial institutions, such as mutual funds and insurance companies, actively trade in the foreign exchange market. Central banks intervene in the market to influence the value of their national currency, maintain foreign exchange reserves, and implement exchange rate policies.

The interbank market is the wholesale market where banks trade foreign currency among themselves. Banks quote exchange rates at which they are willing to buy and sell currencies. Interbank trading accounts for most foreign exchange transactions and may involve foreign exchange brokers to facilitate transactions.

Speculators aim to profit from anticipated changes in exchange rates by trading directly in the market. Arbitrageurs profit from differences in exchange rates between different markets simultaneously. Savers who want to hedge against inflation may convert their money holdings into foreign currency to protect the real value of their income against inflation, a phenomenon commonly referred to as dollarization.

The foreign exchange rate is the price of one country's currency in terms of another country's currency. It is crucial in the global economy as it enables the comparison of the value of goods and services produced in different countries, facilitating international trade and investment.

Bid rate: The rate applied by banks and intermediary institutions in foreign currency purchase transactions.

Ask rate: The rate applied in sales transactions. The difference between the bid and ask prices is called the foreign exchange spread. The spread contributes to the overall cost of the currency transaction.

The foreign exchange spread is calculated as the difference between the ask rate and the bid rate, divided by the ask rate, multiplied by 100. Factors such as trading volume, market expectations, transaction type, and location influence the magnitude of the spread.

The nominal exchange rate represents the price of one country's currency in terms of another country's currency, as commonly seen in financial sections of newspapers or online economic sites. On the other hand, the real exchange rate adjusts the nominal exchange rate for differences in price levels across countries, indicating the relative price of foreign goods in terms of domestic goods.

Changes in the real exchange rate are significant because they reflect the relative competitiveness of goods and services between countries, considering differences in price levels. While changes in the nominal exchange rate provide information about currency values, changes in the real exchange rate offer a more accurate assessment of relative competitiveness by incorporating price level differences.

Changes in the real exchange rate impact the relative competitiveness of goods between countries. An increase in the real exchange rate indicates a depreciation of the domestic currency in real terms, making domestic goods relatively cheaper compared to foreign goods. Conversely, a decrease in the real exchange rate indicates an appreciation of the domestic currency in real terms, making domestic goods relatively more expensive compared to foreign goods. Therefore, changes in the real exchange rate affect the competitiveness of goods in international markets.

Spot exchange rates are the exchange rates governing current or immediate currency transactions, where two parties agree to exchange currencies and the deal is executed immediately or within two business days. On the other hand, forward exchange rates are the exchange rates regarding future transactions, where two parties agree today to exchange a specific amount of a foreign currency at a specific future date at a rate agreed upon today.

Forward exchange rates are determined based on negotiations between two parties in the present for a future currency exchange. The agreed-upon rate is based on the current spot rate and adjusted for factors such as interest rate differentials between the two currencies and expectations of future currency movements.

A forward discount occurs when the forward exchange rate is lower than the spot rate, indicating that the foreign currency is trading at a discount with respect to the domestic currency. It means that less domestic currency is required to purchase one unit of foreign currency at the forward date than today. The forward discount is calculated as the percentage difference between the forward rate and the spot rate, expressed either as an annualized percentage or for the specific period of the forward contract.

Arbitrage refers to the practice of exploiting price differences in different markets to make a profit. In the context of foreign exchange markets, arbitrage involves buying a currency at a lower price in one market and selling it at a higher price in another market to profit from the price differential.

High-speed computer linkages among different trading centers, electronic communication systems, and integration of financial centers contribute to the rapid transmission of information in foreign exchange markets. This reduces the occurrence of arbitrage opportunities and ensures that price differentials are quickly adjusted.

Hedging refers to the avoidance or insurance against foreign exchange risk, which involves the possibility of adverse changes in exchange rates affecting firms' financial outcomes. It is important for firms to hedge against foreign exchange risk because unanticipated adverse changes in exchange rates can have negative consequences on their financial performance.

If contracts are denominated in Turkish liras instead of pounds sterling, UK exporters would bear the risk of adverse changes in exchange rates. In this scenario, any depreciation of the Turkish lira against the pound would result in lower revenue for UK exporters when converting Turkish lira proceeds into pounds sterling. Therefore, UK exporters may also engage in hedging strategies to mitigate the risk of adverse changes in exchange rates.

Speculation in the foreign exchange market refers to making a profit by buying a currency expected to increase in price and selling a currency expected to decrease in price based on predictions of future exchange rate movements. Unlike hedging, where firms aim to minimize risk, speculation involves accepting foreign exchange risk in order to profit from anticipated changes in exchange rates.

In arbitrage transactions, the aim is to make a risk-free profit by simultaneously buying a currency at a low price and selling it at a higher price across different markets. Conversely, speculation involves taking on risk by waiting for a certain period before selling the currency bought at a higher price, with the potential for expectations to not materialize, leading to losses. Therefore, speculation is inherently riskier than arbitrage.

Several factors contribute to the demand for foreign currency:

• Firms and households that want to buy goods and services from another country: This includes individuals and businesses in one country seeking to purchase goods and services produced in another country, such as Turkish consumers wanting to buy a German car or Turkish tourists needing to exchange Turkish lira for euros to spend in France.
• Firms and households that want to invest in another country: Individuals and businesses may desire foreign currency to make foreign investments through foreign portfolio investments or foreign direct investments, such as Turkish firms building factories in Greece or Turkish investors buying stocks or bonds issued in the US.
• Currency traders that try to make profits stemming from foreign exchange changes: Some investors engage in currency trading for speculative purposes, aiming to profit from anticipated changes in exchange rates by buying foreign currency at a lower price and selling it at a higher price in the future.

Several factors contribute to the supply of foreign currency:

• Foreign firms and households that want to buy home country goods and services: Foreign entities purchasing goods and services produced in the home country contribute to the supply of foreign currency, such as foreign tourists needing to buy Turkish lira to spend in Turkey.
• Foreign firms and households that want to invest in the home country: Foreign direct investments and foreign portfolio investments in the home country, such as foreign companies building plants or purchasing financial assets in Turkey, contribute to the supply of foreign currency.
• Currency traders that try to make profits stemming from foreign exchange changes: Speculators may supply foreign currency to the home market based on their expectations of future changes in exchange rates, such as selling US dollars and buying Turkish lira if they expect the Turkish lira to increase in value relative to the dollar.

Currency depreciation refers to a situation where one currency becomes cheaper in terms of another currency. It occurs when there is an increase in the home currency price of the foreign currency. Currency appreciation, on the other hand, refers to a situation where one currency becomes more expensive in terms of another currency. It occurs when there is a decrease in the home currency price of the foreign currency. These movements in exchange rates have significant implications for trade. For example, if the Turkish lira depreciates against the US dollar, Turkish exports become more expensive for foreigners, while US imports become cheaper for Turkish consumers. This can lead to changes in trade patterns, with more exports from the depreciating currency country and fewer imports into it.

Changes in a country's income can impact the exchange rate through changes in import demand. When a country's income increases, its demand for imports also tends to increase. This leads to a higher demand for foreign currency to purchase those imports, which in turn increases the supply of the country's currency in the foreign exchange market. For example, if Turkey's income increases faster than Argentina's income, Turkish consumers will have more income and spend more, leading to an increase in demand for Argentine exports and currency. Consequently, the Argentine peso appreciates against the Turkish lira.

Changes in relative prices between countries can influence exchange rates by affecting import and export demand. When domestic prices rise rapidly in one country (e.g., Turkey), foreign goods become relatively cheaper compared to domestic goods. This prompts consumers to seek out lower-priced imports, increasing the demand for foreign currencies and decreasing the foreign demand for the domestic currency. As a result, the supply curve for the domestic currency shifts outward, while the demand curve shifts inward, leading to depreciation of the domestic currency. For instance, if Turkey experiences higher inflation than Argentina, the demand for Argentine exports and currency would increase, causing the Turkish lira to depreciate against the Argentine peso.

The Law of One Price states that in a competitive market with no transportation costs or barriers to trade, identical goods should have the same price when expressed in terms of the same currency. If there are price differences for identical goods across different markets, arbitrage opportunities arise, where traders can buy low-priced goods in one market and sell them at a higher price in another market, thereby equalizing prices. This principle is crucial in international trade as it ensures that price differences between countries are minimized, leading to efficient allocation of resources and promoting trade.

Absolute Purchasing Power Parity (PPP) Theory is based on the Law of One Price and postulates that the exchange rate between two currencies should equal the ratio of the price levels in the respective countries. In other words, under absolute PPP, a "basket of goods" should have the same price in all countries when measured in terms of the same currency. This theory suggests that each currency has identical purchasing power in all countries, assuming no transaction costs or trade barriers.

Uncovered interest arbitrage refers to the international transfer of short-term capital to exploit differences in interest rates between countries without hedging against exchange rate risk. An example of uncovered interest arbitrage is when an investor borrows funds in a country with low-interest rates and invests them in a country with higher interest rates, aiming to profit from the interest rate differential. However, the investor is exposed to foreign exchange risk as the exchange rate may fluctuate during the investment period.

Covered interest arbitrage involves hedging against exchange rate risk by using forward exchange markets. In covered interest arbitrage, the investor enters into simultaneous transactions in the spot and forward exchange markets to lock in a future exchange rate, thereby eliminating foreign exchange risk. This differs from uncovered interest arbitrage, where the investor does not hedge against exchange rate risk and is exposed to fluctuations in the exchange rate.
