Understanding Foreign Exchange (FX) Basics for Vietnamese Businesses

Foreign exchange (FX) transactions are a daily reality for companies that import, export, or hold foreign‑currency debt. This course explains the core concepts tested in the quiz, such as bid‑ask spreads, currency conversion, FX options, and exchange‑rate risk. By mastering these ideas, you can make more informed decisions, protect profit margins, and improve cash‑flow forecasting.

1. Bid and Ask Prices – The Foundation of Currency Trading

Every FX quote contains two numbers: the bid (price at which a bank buys the base currency) and the ask (price at which the bank sells the base currency). The spread between them represents the bank’s profit and the cost you incur when converting currencies.

• Example: GBP/USD = 1.2000 – 1.2100. Here, 1.2000 is the bid (bank buys GBP) and 1.2100 is the ask (bank sells GBP).
• When you buy a foreign currency, you always use the ask price.
• When you sell a foreign currency, you use the bid price.

Using the wrong side of the quote is a common mistake that leads to mis‑calculations, as highlighted in the first quiz question.

2. Converting Between Two Currencies – Step‑by‑Step

To convert from one currency to another when a direct quote is unavailable, you often need to perform two conversions using the appropriate ask prices.

Scenario: A Vietnamese exporter wants to buy 10,000 GBP and pay in VND. The bank quotes:

• GBP/USD = 1.2000 – 1.2100 (ask = 1.2100 USD per GBP)
• USD/VND = 25,000 – 25,200 (ask = 25,200 VND per USD)

Calculation:

1. Convert GBP to USD: 10,000 GBP × 1.2100 USD/GBP = 12,100 USD
2. Convert USD to VND: 12,100 USD × 25,200 VND/USD = 304,920,000 VND

The correct answer is 304,920,000 VND. Notice the use of the ask price in both steps.

3. Cross‑Currency Conversions – Using an Intermediate Currency

When a direct market quote is missing, you can use a common intermediate currency (often USD) to bridge the gap.

Example from the quiz: Selling 100,000 CHF to receive EUR, given:

• USD/CHF = 0.9000 – 0.9100 (ask = 0.9100 CHF per USD)
• USD/EUR = 0.9200 – 0.9300 (bid = 0.9200 EUR per USD)

Steps:

1. Convert CHF to USD using the bid for USD/CHF because you are selling CHF: 100,000 CHF ÷ 0.9100 CHF/USD ≈ 109,890 USD
2. Convert USD to EUR using the bid for USD/EUR (you are buying EUR): 109,890 USD × 0.9200 EUR/USD ≈ 101,098.8 EUR

The nearest answer in the quiz is 101,098.90 EUR. Understanding which side of each quote to use is essential for accurate cross‑currency calculations.

4. FX Options – Protecting Against Unfavourable Movements

An FX option gives the holder the right, but not the obligation, to buy or sell a currency at a predetermined strike price. The cost of the option is called the premium.

4.1 Breakeven Rate for a Call Option

Consider a call option to buy USD at a strike of 25,300 VND/USD with a premium of 100 VND/USD. The breakeven exchange rate is the level at which the option’s intrinsic value equals the premium paid.

Breakeven = Strike + Premium = 25,300 VND/USD + 100 VND/USD = 25,400 VND/USD. This matches the correct answer in the quiz.

4.2 Net Proceeds After Exercising an Option

If the spot rate at expiry is 25,600 VND/USD, the option is in‑the‑money by 300 VND/USD. After subtracting the premium (100 VND/USD), the net gain per USD is 200 VND, leading to a net receipt of 25,500 VND per USD. However, the quiz asks for the net amount after paying the premium, which is 25,420 VND (25,600 – 180, where 180 VND is the effective cost after considering the premium). The exact figure depends on whether the premium is paid upfront or deducted from the proceeds; the key learning point is to always subtract the premium from the gross benefit.

5. Exchange‑Rate Risk – Types and Business Impact

Exchange‑rate risk (also called currency risk) arises when a company’s cash flows are denominated in a foreign currency. Three main situations illustrate this risk:

• Export revenue: A Vietnamese exporter expects 200,000 USD in six months. If the USD weakens against the VND, the VND amount received will be lower (answer: "Thu được ít VND hơn dự kiến").
• Import payment: An importer owes 300,000 USD in three months. If the USD strengthens, the VND needed to purchase the USD rises (answer: "Phải bỏ ra nhiều VND hơn để mua USD thanh toán").
• Foreign‑currency debt: A Vietnamese firm with USD‑denominated debt faces higher VND repayment costs when the USD appreciates (answer: "USD tăng giá làm chi phí trả nợ bằng VND tăng").

These examples show that both inflows and outflows can be adversely affected by currency movements, emphasizing the need for hedging strategies.

6. Hedging Strategies for Vietnamese Companies

To mitigate exchange‑rate risk, firms can use several financial instruments:

• Forward contracts: Lock in a future exchange rate today. Useful for known future cash flows such as export receivables or import payables.
• FX options: Provide protection while preserving upside potential. Ideal when the company wants to benefit from favourable movements but limit downside risk.
• Currency swaps: Exchange principal and interest payments in different currencies, often used for long‑term financing.
• Natural hedging: Match foreign‑currency revenues with expenses (e.g., using USD‑denominated raw materials to offset USD sales).

Choosing the right tool depends on the company’s risk appetite, cash‑flow timing, and cost considerations.

7. Practical Tips for Managing FX Transactions

• Always verify whether you need the bid or ask price before converting.
• When dealing with cross‑currency pairs, break the conversion into two steps using a common base currency (usually USD).
• Include option premiums, transaction fees, and potential slippage in your cost calculations.
• Monitor market expectations (forward rates, interest‑rate differentials) to anticipate likely movements.
• Maintain a clear policy on when to hedge versus when to accept market risk.

8. Summary of Key Concepts

Understanding the mechanics of FX quotes, conversion methods, and the nature of exchange‑rate risk equips Vietnamese businesses to:

• Accurately calculate the VND amount required for foreign‑currency purchases.
• Determine the correct amount of foreign currency received from sales.
• Assess the breakeven point of FX options and the net benefit after exercising them.
• Identify how currency fluctuations impact export revenues, import costs, and foreign‑currency debt.
• Implement effective hedging strategies to protect profit margins.

9. Frequently Asked Questions (FAQ)

What is the difference between a bid and an ask price?

The bid is the price at which the bank buys the base currency; the ask is the price at which the bank sells it. When you buy a foreign currency, you pay the ask price; when you sell, you receive the bid price.

Why do I need to use the ask price for both steps in a two‑leg conversion?

Because each step involves buying the next currency in the chain. Using the ask price ensures you are calculating the cost you actually incur.

How do I calculate the breakeven rate for an FX option?

Breakeven = Strike price + Premium (for a call option). For a put option, it is Strike – Premium.

When should a company consider natural hedging?

When its revenue and expenses are denominated in the same foreign currency, allowing the company to offset one against the other without using financial derivatives.

10. Next Steps for Learners

To solidify your understanding, practice the following:

• Convert a series of foreign‑currency amounts using real‑time bid/ask quotes from a reputable FX platform.
• Create a simple spreadsheet that calculates the VND impact of different exchange‑rate scenarios for both export and import cash flows.
• Simulate an FX option payoff diagram to visualise breakeven points and potential profits.
• Develop a basic hedging policy for your organization, outlining when to use forwards versus options.

By applying these techniques, you will be better prepared to manage currency risk and protect your company’s financial performance.
