"Currency Exchange for Profit" Beginner's Must-Read: The Complete Guide to Foreign Currency Investment

Looking to profit in the international financial markets but don’t know where to start? Compared to depositing NT$1.7% annual interest in a bank savings account, currency exchange has become an increasingly popular way for Taiwanese investors to make money. This article will give you a comprehensive understanding of the core principles, practical methods, and risk management strategies for foreign currency investing, helping you develop a profit strategy suited to your goals.

Comparison of the Three Main Currency Trading Profit Methods

To participate in foreign currency investment, choosing the right tool is essential. In Taiwan, there are three main investment options, each with its pros and cons:

Foreign Currency Fixed Deposit: A Stable Interest Rate Harvestor

This is the simplest entry method. Anyone over 20 can open a foreign currency account at a bank (e.g., E.SUN Bank). USD fixed deposit rates are about 5%, nearly three times higher than Taiwan’s 1.7%, which exemplifies the “interest rate spread”—one of the core ways to profit from currency exchange.

However, foreign currency fixed deposits have a critical flaw: very low liquidity. If the exchange rate has reached your target but the deposit term isn’t over, early withdrawal incurs interest penalties. Many investors then turn to the next option.

Foreign Currency Funds: Balancing Flexibility and Returns

Foreign currency funds require no lock-in period; you can buy and sell anytime. The returns are between savings and fixed deposits. You can invest directly in TWD, with the fund company handling currency conversion. Common options include:

• UBS USD Fund: invests in USD-related products, management fee ~0.5%
• Yuan Tai USD Index ETF (00682U): tracks the USD index, fee ~0.6%

This approach suits investors who need capital flexibility but want stable profits.

Forex Margin Trading: Fast Profits with High Leverage

If fund returns are insufficient, forex margin trading is an advanced choice. It doesn’t earn interest but profits from “exchange rate differences.” By leveraging (usually 50-200x), investors can control large positions with small capital.

Note: The Australian ASIC regulator recommends that leverage for major currency pairs should not exceed 30x. Higher leverage increases the risk of margin calls. This method is suitable only for those with trading experience.

Essential Market Basics Before Buying Foreign Currency

Two Main Income Sources from Currency Trading

Many people don’t understand why buying foreign currency can be profitable. Simply put, it’s about earning “interest rate spread” and “exchange rate difference”:

1. Interest Rate Spread — The Difference Between Countries’ Interest Rates

Example:

• Taiwan fixed deposit rate: 2%
• US fixed deposit rate: 5%
• Spread: 3%

Theoretically, converting NT$ to USD and depositing in the US bank earns 3% interest. But don’t celebrate too early…

2. Exchange Rate Difference — Profit or Loss from Currency Fluctuations

This is the key risk. Suppose you exchange NT$33 for 1 USD, earning 5% interest in USD after a year, but the USD depreciates to NT$30. The result: earned 5% interest but lost about 9.1% on the exchange rate difference, resulting in overall loss. This classic scenario is “interest rate spread gain but exchange rate loss.”

Therefore, before investing, clarify your goal: Are you seeking stable interest income or short-term exchange rate gains?

Currency Types and Strategies for Beginners

Four Types of Currencies and Their Characteristics

Taiwan banks typically offer 12 foreign currencies, but not all are suitable for beginners. Categorized by exchange drivers:

Policy-Driven Currencies (USD, EUR)

• Exchange rates mainly influenced by central bank policies
• Rate cuts → currency depreciation; rate hikes → appreciation
• Need to monitor central bank meetings closely

Safe-Haven Currencies (JPY, CHF)

• Known for “stability, neutrality, safety”
• During economic turmoil, funds flow into these currencies
• Suitable for risk-averse investors or short-term hedging

Commodity Currencies (AUD, CAD)

• Exchange rates follow commodity prices
• e.g., Iron ore price rise → AUD appreciation; oil price rise → CAD appreciation
• Clear trends, relatively easy to grasp, especially suitable for beginners

Emerging Market Currencies (CNY, ZAR)

• Attractive interest rates (ZAR > 8% annually)
• But high risk: political instability, low liquidity, large bid-ask spreads
• Not recommended for beginners

Best Currency Portfolio for Beginners

Based on recent market performance, beginners should combine safe-haven and commodity currencies:

• Core holdings: USD (global settlement currency) + AUD (easy to understand)
• Hedging: JPY or CHF (buy during market turbulence)
• Special situations: When central banks have clear policy signals, consider long positions in those currencies

2026 Mainstream Currency Investment Analysis

EUR/USD

The most traded currency pair, representing the economic strength of Europe and the US.

Latest Trend: After the Fed started rate cuts in September 2024, totaling 100 basis points by 2025, the ECB maintained rates in September 2025. Divergence in policies led EUR/USD to a four-year high.

Outlook: Market doubts about US dollar independence due to Trump’s economic reforms have weakened USD. The euro benefits from more stable ECB policies, making it a relatively better choice.

USD/JPY

The most popular carry trade currency pair—borrowing low-interest JPY to invest in high-interest countries for profit.

Latest Movement: The Bank of Japan paused rate hikes in January 2025, awaiting US tariff impacts. Most analysts expect a 25 basis point hike by year-end. The narrowing US-Japan interest differential is a trend.

Trading Tip: Short-term divergences create volatility opportunities, but long-term, the yen may appreciate. Political changes in Japan could act as catalysts.

GBP/USD

The pound has strengthened this year, but not due to UK economic improvement—it’s mainly because the USD has weakened.

Risk Warning: As Fed policies become clearer, markets may reprice the pound. UK economic growth remains sluggish, with rate cut expectations, so the pound is likely to stay in a range.

USD/CHF

The Swiss franc, a traditional safe-haven currency, gains value during US trade and fiscal issues.

Long-term Outlook: US economic slowdown, Fed rate cuts, and a weakening dollar favor the Swiss franc. It is expected to remain attractive to international capital.

Five Major Drivers of Exchange Rate Fluctuations

1. Inflation Rate

Lower inflation countries’ currencies tend to appreciate because low inflation preserves purchasing power, making their assets more attractive.

2. Interest Rate Levels

Higher interest rates attract foreign capital, leading to currency appreciation.

3. Government Debt

High debt levels deter foreign investment. If markets expect default or inability to repay, the currency will depreciate.

4. Trade Conditions

If export prices rise faster than import prices, national income increases, boosting currency demand and appreciation. The relationship between iron ore prices and AUD is a prime example.

5. Political Stability

Countries with stable politics and sound fiscal policies attract investment, supporting currency strength. Political turmoil causes sharp depreciation.

Practical Trading: From Currency Selection to Profit

Step 1: Define Your Trading Goal

Before trading, answer: Are you aiming for interest rate spread income or exchange rate gains?

• Spread-focused: Choose high-interest currencies, fixed deposits, or funds for steady income.
• Exchange rate-focused: Analyze central bank policies, commodity trends, economic data, and use margin trading for quick profits.

Step 2: Choose Suitable Currency Pairs

Beginners should start with major pairs: EUR/USD, USD/JPY, GBP/USD, AUD/USD.

Example decision process:

• Expect US rate cuts but Japan holds steady → Long USD/JPY
• Bullish on Australian economy but bearish on iron ore → Short AUD/USD
• Concerned about US policy uncertainty → Buy CHF for safety

Step 3: Develop a Trading Strategy

Three key elements:

Entry Point: Avoid chasing highs or selling lows. Wait for clear trend signals—using 30-minute or 2-hour charts for confirmation.

Stop-Loss: Essential for risk control. Set stop-loss below recent support by 5-10%. Stick to it strictly.

Take Profit: Exit when profit target is reached. Don’t be greedy; currency fluctuations are limited.

Day Trading Tip: Limit to 2 trades per day to maintain discipline.

Step 4: Continuous Monitoring and Adjustment

Currency markets are volatile and influenced by multiple factors. Keep track by:

• Following financial media (CNBC, Bloomberg, Yahoo Finance, Investing.com)
• Marking key central bank meeting dates
• Monitoring commodity prices
• Watching geopolitical risks

Psychological Traits and Risk Management in Currency Trading

Common Mistakes by Beginners

Mistake 1: Believing diversification alone reduces risk

Incorrect! Currency risk stems from exchange rate volatility, not diversification. Proper risk control involves stop-loss, take-profit, and appropriate leverage.

Mistake 2: Investing blindly in high-interest currencies

High interest (e.g., ZAR >8%) can be tempting, but political instability, low liquidity, and large bid-ask spreads can wipe out gains quickly.

Mistake 3: Using excessive leverage for quick riches

Leverage of 100x sounds exciting but can wipe out your capital with just 1% adverse move. Most retail traders end up losing everything. ASIC recommends a maximum of 30x leverage.

Mistake 4: Letting emotions drive decisions

Market rallies or declines can tempt impulsive actions. The key is to plan your trades and stick to the plan.

Five Risk Control Rules

1. Use Regulated Platforms

• Verify regulatory licenses (ASIC, FCA, SFC, etc.)
• Mitrade, regulated by ASIC and CIMA, is a good example
• Avoid unregulated or underground brokers

2. Proper Capital Allocation

• Limit high-risk investments to 20% of total assets
• Use small amounts (e.g., 1% of capital per trade) for beginners
• Practice with demo accounts for at least 3 months

3. Strict Stop-Loss Enforcement

• Set stop-loss before entering trades
• Exit immediately at stop-loss levels
• Protect capital over chasing profits

4. Regular Review and Learning

• Monthly review of trades
• Study technical and fundamental analysis
• Participate in advanced demo courses

5. Maintain Calm and Discipline

• Don’t be discouraged by losses; multiple trades reveal strategy effectiveness
• Stop trading after consecutive losses to analyze
• Avoid using leverage to recover losses impulsively

Investment Stage Recommendations

Stage 1: Complete Beginner (First 3 months)
