Dollar
Overview
The dollar (USD) is the official currency of the United States and the most widely used reserve currency in the world. It serves as the standard for international trade, foreign exchange reserves, and financial transactions. Under the Bretton Woods system, the dollar was pegged to gold, but after the Nixon Shock in 1971, it transitioned to a floating exchange rate system. Currently, the U.S. Federal Reserve (Fed) oversees monetary policy, and the value of the dollar has a profound impact on the global economy and financial markets.

Historical Background
- Gold Standard and Bretton Woods System (1944–1971): After World War II, the Bretton Woods Agreement fixed the dollar at $35 per ounce of gold, and other countries pegged their currencies to the dollar. This made the dollar the center of international settlement and reserve currencies.
- Nixon Shock (1971): President Richard Nixon suspended gold convertibility, causing the collapse of the Bretton Woods system and a shift to floating exchange rates. Since then, the dollar has maintained its value as pure fiat money based on credit.
- Modern Dollar: Since the 1970s, the dollar has maintained a dominant position in oil transactions (petrodollar), international bond markets, and foreign exchange reserves, serving as the foundation of the U.S. economy.
International Role of the Dollar
- Reserve Currency: According to the International Monetary Fund (IMF), approximately 59% of global foreign exchange reserves are denominated in dollars (as of 2024). Most international commodity transactions (oil, gold, grains) are settled in dollars.
- Trade Settlement: About 40% of global trade is conducted in dollars, with countries in Asia and the Middle East particularly using the dollar as a primary settlement currency.
- Financial Markets: U.S. Treasury bonds are considered the safest assets in the world, and dollar-denominated bond markets account for about 40% of the global bond market.
- Dollar Index (DXY): An index measuring the value of the dollar against six major currencies (euro, yen, pound, Canadian dollar, Swedish krona, Swiss franc), serving as a barometer for global financial markets.
Factors Determining the Dollar's Value
- Federal Reserve (Fed) Monetary Policy: Interest rate hikes strengthen the dollar, while rate cuts weaken it. The Fed's aggressive rate hikes in 2022–2023 significantly strengthened the dollar.
- Economic Indicators: GDP growth, employment, inflation (CPI), and trade balance affect the dollar's value. A strong U.S. economy typically leads to a strong dollar.
- Geopolitical Risks: During wars, trade disputes, or geopolitical crises, the dollar strengthens due to safe-haven demand. For example, the dollar surged during the Russia-Ukraine war (2022).
- Global Supply and Demand: Demand for dollars from other countries (e.g., commodity importers, debt repayment) also influences its value.
Advantages and Disadvantages of the Dollar
- Advantages: International trust, liquidity, and stability, supported by the size of the U.S. economy, military power, and rule of law. The dollar is also used as an inflation hedge.
- Disadvantages: U.S. monetary policy creates 'spillover effects' on the global economy, burdening emerging markets. In response to dollar hegemony, some countries (China, Russia) are pursuing de-dollarization.
Dollar and the Korean Economy
- South Korea, with its high external dependence, is significantly affected by the dollar exchange rate. The won/dollar exchange rate directly impacts export price competitiveness, import prices, and foreign debt repayment.
- As of 2024, the won/dollar exchange rate fluctuates around the 1,300 won range, reacting sensitively to the Fed's interest rate policy and global economic slowdown.
- The Bank of Korea manages most of its foreign exchange reserves in dollar assets (e.g., U.S. Treasury bonds) and intervenes in the market to stabilize the exchange rate.
Recent Trends
In 2024–2025, the dollar has maintained a strong trend. Although the Fed began cutting interest rates in the second half of 2024, the dollar remains strong due to robust U.S. economic growth and a strong labor market. Key trends include:
- De-dollarization Movements: BRICS countries are building their own currency settlement systems, and China is promoting the internationalization of the yuan, but a substantial replacement is far off. According to IMF data, the dollar's share of foreign exchange reserves fell from 71% in 2000 to 59% in 2024, but it remains dominant.
- Digital Dollar (CBDC): The Fed is researching the introduction of a digital dollar, with a pilot project expected in 2025. This is anticipated to improve payment efficiency and financial inclusion.
- Geopolitical Impact: U.S.-China tensions, sanctions on Russia, and instability in the Middle East sustain demand for the dollar. In particular, after the freezing of Russian assets, some countries are moving to reduce their dollar dependence.
- Inflation and Interest Rates: In early 2025, the U.S. CPI slowed to around 3%, but tariff policies (Trump administration) could stimulate inflation, suggesting a cautious approach by the Fed.
