## What Is International Finance?

International finance, often referred to as international macroeconomics, explores the financial relationships and monetary dynamics that take place between countries. It focuses on areas such as foreign direct investment and currency exchange rates.

### Key Takeaways

*   International finance evaluates monetary activity and is crucial due to globalization.  
    
*   The Bretton Woods system was established to standardize international monetary policies post-World War II.  
    
*   Key areas of international finance include foreign direct investment, currency exchange rates, and the Mundell-Fleming Model.  
    
*   Institutions like the International Monetary Fund and World Bank play foundational roles in international finance.

## Key Concepts in International Finance

International finance examines how countries interact economically, not just in single markets. International finance research is conducted by large institutions such as the [International Finance Corp.](https://www.investopedia.com/terms/i/international-finance-corporation.asp) (IFC), and the [National Bureau of Economic Research](https://www.investopedia.com/terms/n/nber.asp) (NBER). Furthermore, the U.S. Federal Reserve has a division dedicated to analyzing policies germane to U.S. capital flow, external trade, and the development of global markets.

International finance analyzes the following specific areas of study:

*   **The Mundell-Fleming Model**, which studies the interaction between the goods market and the money market, is based on the assumption that price levels of said goods are fixed.
*   [**International Fisher Effect**](https://www.investopedia.com/articles/economics/10/international-fisher-effect.asp) is an international finance theory that assumes nominal interest rates mirror fluctuations in the spot exchange rate between nations.
*   **The optimum currency area theory** states that certain geographical regions would maximize economic efficiency if the entire area adopted a single currency.
*   **Purchasing power parity** is the measurement of prices in different areas using a specific good or a specific set of goods to compare the absolute purchasing power between different currencies.
*   **Interest rate parity** describes an equilibrium state in which investors are indifferent to interest rates attached to bank deposits in two separate countries.

## Leading Institutions in Global Finance

### The Bretton Woods System

The [Bretton Woods system](https://www.investopedia.com/terms/b/brettonwoodsagreement.asp) was created at the Bretton Woods conference in 1944, where the 40 participating countries agreed to establish a fixed exchange rate system. The collective goal of this initiative was to standardize international monetary exchanges and policies in a broader effort to create post World War II stability.

The Bretton Woods conference catalyzed the development of international institutions that play a foundational role in the global economy. These include the [International Monetary Fund](https://www.investopedia.com/terms/i/imf.asp) (IMF), a consortium of 189 countries dedicated to creating global monetary cooperation, and the [International Bank for Reconstruction and Development](https://www.investopedia.com/terms/i/international-bank-of-reconstruction-and-development.asp), which later became known as the World Bank.

## Important Considerations in International Finance

International trade is a major driver of global prosperity and growth. However, concerns exist because the U.S. went from being the biggest international creditor to the largest debtor, taking in lots of global funding. This shift could impact international finance in unexpected ways.
