Foreign Currency Investment Beginner's Guide: Essential Investment Strategies and Currency Selection for Beginners

Looking to achieve financial growth through foreign currency investment? In the era of low interest rates, many investors are turning to foreign currency investments in search of higher returns. But how to choose the right investment method, assess risks, and develop strategies—these are essential lessons for beginners to master.

In Taiwan, all currencies other than the New Taiwan Dollar belong to the foreign currency category. The US Dollar, Japanese Yen, Australian Dollar, and others are the most commonly watched targets by Taiwanese investors. However, the core risk of foreign currency investment comes from exchange rate fluctuations, which is why developing a scientific investment strategy is especially important.

Understanding the Difference Between Foreign Currency and Forex

Many people often confuse the concepts of “foreign currency” and “forex.” Foreign currency refers to non-domestic currencies, a form of foreign exchange. Investors make investment decisions by observing the exchange rate movements of various foreign currencies.

Forex (foreign exchange) refers to assets held by a country expressed in foreign currencies and payment methods used for international settlement, including bank deposits, government bonds, etc. In short, buying and selling foreign currencies is a specific form of forex trading.

Sources of Returns in Foreign Currency Investment: Interest Rate Differentials and Exchange Rate Margins

Currencies, like bonds, generate returns mainly from two parts: interest rate differentials and exchange rate margins.

Interest rate differential refers to the difference in benchmark interest rates between countries. For example, if Taiwan’s fixed deposit rate is 2% and the US is 5%, the 3% gap represents potential profit. But this profit is not guaranteed. If an investor exchanges 33 TWD for 1 USD, and due to exchange rate fluctuations, they can only exchange back 30 TWD, even if they earn 5% interest on USD, overall they might still incur a loss. This is a typical case of “earning interest but losing on the exchange rate.”

Exchange rate margin arises from price differences at different trading times. Investors need to clarify their goals before trading—whether to pursue higher interest income or to capture short-term price differences. They must also fully evaluate related risks to develop a comprehensive investment plan.

How to Choose Among Three Foreign Currency Investment Methods

In Taiwan, the common foreign currency investment methods include three types:

Foreign currency fixed deposit is the simplest choice and most suitable for beginners. Investors only need to open a foreign currency account at a bank to participate, with low barriers and low risk. Fixed deposits offer stable interest income but limited liquidity—if the exchange rate reaches the target but the deposit term is not yet over, early withdrawal will incur interest deductions.

Foreign currency funds offer greater flexibility, with no lock-in period, and can be bought and sold at any time. The interest rates are usually between savings and fixed deposits. Investors can invest directly in TWD, with the fund company handling currency exchange on their behalf. Returns come from interest income and exchange rate differences. Common options include money market funds and related ETFs, with management fees typically between 0.5% and 0.6%.

Forex margin trading is aimed at investors with certain experience. This method does not pursue interest but profits solely from exchange rate differences. Due to lower volatility, leverage of 50 to 200 times is often used. It can be traded 24 hours a day with T+0 mechanisms, low entry barriers, but higher risks. Investors need to learn to analyze exchange rate trends and choose optimal entry times.

Most Common Foreign Currencies Chosen by Taiwanese Investors

Banks in Taiwan generally offer about 12 foreign currencies for investment, including USD, AUD, CAD, HKD, GBP, CHF, JPY, EUR, NZD, SGD, ZAR, etc. These currencies can be grouped into four categories based on influencing factors:

Policy currencies (USD, EUR): Exchange rates are mainly affected by central bank monetary policies. Loose policies usually lead to depreciation, tight policies to appreciation. Investing in these currencies requires close attention to central bank policy movements.

Safe-haven currencies (JPY, CHF): Represent stable economies with low political risk, and central banks rarely adjust interest rates. During market turbulence, these currencies are often sought after. Investors can profit through arbitrage strategies by borrowing in low-interest-rate currencies and investing in high-interest-rate currencies.

Commodity currencies (AUD, CAD): Highly correlated with commodity prices. Australia is the largest exporter of iron ore; when iron ore prices fall, the AUD tends to weaken. The price trends of these currencies are relatively easier to grasp, making them suitable for beginners to participate through trend trading strategies.

Emerging market currencies (CNY, ZAR): From developing countries, with generally higher interest rates but high political risks, volatile exchange rates, and limited liquidity. Investment should be cautious—high interest rate spreads may be attractive, but risks of exchange rate fluctuations are significant.

Currency selection advice: Beginners should prioritize stable, highly liquid currencies such as USD, EUR, and AUD. Combining safe-haven and commodity currencies can ensure stable returns while allowing trend analysis. High-interest emerging market currencies are tempting but require thorough risk assessment.

Key Factors Influencing Exchange Rate Fluctuations

Investing in foreign currencies requires understanding the root causes of exchange rate movements. The main influencing factors include:

Inflation rate: Countries with low inflation tend to see their currencies appreciate because prices of goods and services rise slowly, increasing purchasing power.

Interest rate levels: Rising interest rates attract foreign capital inflows, pushing the currency higher. There is a positive correlation between interest rates and inflation.

Government debt: Countries with high debt levels are less attractive to foreign investors; foreign investors may sell bonds, leading to currency depreciation.

Trade terms: When export prices rise faster than import prices, trade conditions improve, increasing income and currency demand, leading to appreciation.

Political and economic stability: Stable countries attract more foreign investment, causing currency appreciation; political turmoil can lead to depreciation.

How Beginners Can Profit from Foreign Currency Investment

After understanding the investment methods and risk factors, mastering the correct trading mindset is crucial. Forex trading employs a two-way mechanism, different from traditional one-way investments.

Buy low, sell high is straightforward—buy when prices are low, sell when prices rise to earn the spread. But forex markets also support sell high, buy low—when expecting a currency to depreciate, you can sell it first, then buy back after it falls, earning profit. For example, if you expect EUR/USD to depreciate, you can sell EUR/USD first, then buy it back after the euro weakens.

Four key steps for successful trading:

First, select the target: Study the central bank policies, interest rate changes, major exports, etc., of the target currency pair to determine trading direction. For example, if you expect the US to cut interest rates while Japan’s rates stay unchanged, you might go long JPY/USD. This step is the most critical in investment decision-making.

Second, develop a trading strategy: Based on your risk tolerance, trading experience, and market conditions, set entry and exit points, stop-loss, and take-profit levels. Consider market risks and transaction costs to protect capital amid volatility.

Third, maintain a stable mindset: Avoid emotional reactions caused by market fluctuations, which can impair judgment. Keep learning and practicing to accumulate experience.

Fourth, choose a suitable trading platform: The platform should be secure, low-cost, equipped with comprehensive tools, diverse products, and fast execution.

Essential Investment Tips for Beginners

First, only invest in currencies you are familiar with: The forex market offers many options, but the most traded are major pairs like USD, JPY, etc. Focusing on familiar currencies reduces decision difficulty.

Second, closely monitor exchange rate movements: Foreign exchange rates are affected by market, economic, and news factors. Investors should follow international news sites (like Bloomberg, Yahoo Finance) to grasp market rhythm.

Third, perform rational asset allocation: Avoid concentrating all funds in a single currency. Holding both USD fixed deposits and AUD funds can create a complementary hedge. Once well-diversified, frequent daily trading is unnecessary.

Fourth, learn to set stop-loss and take-profit: This is especially important in forex margin trading. Set stop-loss at appropriate levels to prevent excessive losses or margin calls. For example, establish a long position near a previous low, set a stop-loss below that low, and wait for price to rise. If it cannot, close the position. Limit daily trades to a maximum of 2.

Fifth, seize entry timing: Never chase highs or sell in panic. Develop a trading plan in advance, execute when the timing is right, and wait otherwise. The simplest method is to wait for a trend to form. Usually, it takes 5 minutes or longer to confirm a trend; once established, you can participate. Different investors may choose 30-minute, 120-minute, or other timeframes as references.

Current Trends of Major Currency Pairs

In the context of global economic changes, the trends of major currency pairs are worth noting.

EUR/USD(: Involving the competition between the world’s two largest economies, even minor fluctuations can impact the entire forex market. Recently, the Fed cut interest rates while the European Central Bank maintained a steady stance, leading to a relatively strong euro. Market concerns over dollar policy outlooks have also increased euro’s relative attractiveness.

USD/JPY): Commonly used for carry trades. Divergence exists between the Bank of Japan’s policies and the Fed. The US-Japan interest rate spread is expected to narrow. However, domestic political uncertainties in Japan still affect market sentiment, and the yen may continue to fluctuate in the short term.

GBP/USD(: The pound’s strength this year mainly stems from a weak dollar rather than improved fundamentals. As Fed policies become clearer, the bullish momentum faces re-pricing risks. The UK economy shows sluggish growth, and the pound is expected to remain range-bound.

USD/CHF): The Swiss franc is a popular safe-haven currency. Amid global economic uncertainties, its hedging value is more prominent. From a medium- to long-term perspective, slowing US economic growth and the Fed’s rate cuts will support the appreciation of the Swiss franc.

Foreign currency investment is not achieved overnight. Investors need continuous learning, accumulating market knowledge and trading experience. Starting from low-risk fixed deposits, gradually progressing to funds and margin trading, and steadily enhancing investment skills will enable steady growth in the foreign currency market.
