Introduction to the Forex Market: A Global Financial Giant
The foreign exchange market, or Forex (Foreign Exchange), is the largest financial market in the world, with an estimated average daily volume of around 6.7 trillion dollars as of April 2023 (source: Bank for International Settlements - BIS). This decentralized market allows for the instantaneous exchange of currencies and plays a central role in international trade, risk management, and speculation.
This comprehensive guide aims to decode the key mechanisms of Forex, the main currency pairs, popular strategies such as carry trade, as well as the economic factors influencing exchange rates, thus providing French investors with a solid foundation to navigate this complex market.
The Size and Structure of the Forex Market
According to the BIS triennial report published in 2023, the Forex market shows an average daily volume of 6.7 trillion dollars, up from 6.6 trillion dollars in 2020. More than 50% of transactions involve major currencies, notably the US dollar (USD), euro (EUR), Japanese yen (JPY), British pound sterling (GBP), Swiss franc (CHF), Australian dollar (AUD), and Canadian dollar (CAD).
The market is dominated by spot foreign exchange operations, which represent about 30% of the volume, followed by futures contracts, options, and currency swaps. Commercial and investment banks, hedge funds, multinational corporations, and central banks are the main players.

The EUR/JPY Carry Trade: A Popular but Risky Strategy
Carry trade consists of borrowing in a currency with a low interest rate to invest in a currency offering a higher yield. The EUR/JPY pair is one of the most sought after, as the euro generally offers a higher interest rate than the Japanese yen, historically near zero or even negative.
In March 2024, the ECB refinancing rate stands at 3.50% while the Bank of Japan maintains a policy rate at -0.10% (source: ECB, Bank of Japan). This asymmetry encourages investors to borrow in yen to buy euro-denominated assets, profiting from the interest rate differential. However, this strategy carries significant currency risk in case of yen appreciation.
Numerical example: an investor borrows 100 million yen at -0.10% to buy euros yielding 3.50%. Assuming a stable EUR/JPY exchange rate at 140, the gross annual gain would be approximately 3.6 million yen. But a 5% depreciation of the EUR/JPY rate would cancel out this gain or even cause a loss.
Key Factors Driving Currency Fluctuations
Inflation and Monetary Policy
Inflation is a key driver of exchange rates. High inflation tends to devalue a currency if not accompanied by interest rate hikes. Central banks adjust their policy rates to control inflation, thus influencing currency attractiveness.
For example, in 2023, inflation in the eurozone averaged 5.8% annually, prompting the ECB to raise rates to contain price increases (source: INSEE, ECB). Simultaneously, the Fed raised rates to 5.25% in March 2024 to counter US inflation at 4.9% (source: Bureau of Labor Statistics, Fed). These divergences partly explain EUR/USD volatility.
Interest Rates
Real interest rates (nominal rates minus inflation) are crucial. A high real rate attracts foreign capital, strengthening the currency. Conversely, a negative real rate weakens the currency. The interest rate differential between two regions is often the main driver of medium-term exchange rate movements.
Trade Balance
The trade balance, the difference between exports and imports, impacts currency demand. A trade surplus creates demand for the national currency, causing appreciation. Conversely, a deficit puts downward pressure.
Example: in 2023, France recorded a trade deficit of 79 billion euros (source: French Customs), exerting moderate pressure on the euro. Conversely, Japan posted a trade surplus of 9.6 trillion yen, supporting the yen (source: Japanese Ministry of Finance).
Conclusion: Verdict for French Investors
The Forex market, with its 6.7 trillion dollar daily volume, offers considerable opportunities but requires a fine understanding of macroeconomic and geopolitical factors. Major pairs provide optimal liquidity and transparency, while strategies like the EUR/JPY carry trade can generate attractive returns during stable periods but expose investors to high currency risk.
For French investors, it is imperative to closely monitor the evolution of ECB and Fed interest rates, inflation data, and the trade balance. The significant volatility in these markets demands rigorous risk management and prudent diversification.
In summary: Forex is an essential market for portfolio diversification but requires deep expertise and constant monitoring of economic indicators. Caution and fact-based analysis, grounded in real and up-to-date data, are key to exploiting this market profitably and securely.
