Currency, Banking, and Exchange

Purchasing Power Parity Theory

Purchasing power parity (PPP) theory is an economic concept that suggests exchange rates between countries should adjust to reflect changes in the price levels of goods and services between those countries. The logic behind this theory is based on the idea that in a world with perfect capital mobility, people would arbitrage away any differences in the relative prices of the same good or service across borders until the purchasing power of money is equalized among countries. For example, if the price level for a certain product increases in one country but not in another, then the exchange rate between those countries should adjust accordingly to maintain equilibrium.

Exchange Rate Theory

Exchange rate theory refers to the study of how exchange rates are determined in the foreign exchange market. Different theories have been proposed to explain this complex phenomenon, such as the floating exchange rate model, which suggests that exchange rates are affected by supply and demand factors in the currency markets. Another theory is the overshooting model, developed by Rudiger Dornbusch, which explains how changes in real interest rates can affect the exchange rate of a country. Overall, understanding exchange rate theory is crucial for investors and traders, as it helps them predict shifts in currency values and make informed decisions regarding forex trading.

Currency Banking

Currency banking encompasses the activities of financial institutions involved in the movement of funds across national borders. These institutions provide services such as facilitating foreign exchange transactions, managing foreign exchange risk through futures and forwards, and serving as intermediaries between importers and exporters in different countries. Their role is essential in ensuring smooth global trade operations and maintaining liquidity in the world economy.

Foreign Exchange

Foreign exchange, or forex, is the conversion of one currency into another. This process takes place in the foreign exchange market, where participants buy, sell, exchange, and speculate on the relative exchange rates of various currency pairs. The primary function of the foreign exchange market is to establish the relationship (price) between the world's currencies, enabling currency conversions for international trade settlements and investments.

Currency Exchange

Currency exchange involves the direct buying and selling of one currency against another. This can occur physically, through currency exchange booths at airports or banks, or electronically through brokers and dealers in the foreign exchange market. The exchange rate between two currencies is commonly determined by economic activity, market interest rates, gross domestic products, and unemployment rates in each country. The fluctuations of exchange rates can significantly impact businesses, changing the cost of supplies purchased from overseas and affecting the demand for their products from customers abroad.
