With New Taiwan dollar interest rates remaining low, many savvy investors have shifted their focus to USD time deposits, hoping to earn steady returns through higher USD deposit rates. However, with countless offers on the market, from Fubon USD time deposits to promotional plans across various banks, how do you choose the right one? More importantly, beyond attractive rates, do you fully understand the potential risks of foreign currency deposits? This article provides the most comprehensive guide available, including rate comparisons from more than 15 banks and an in-depth analysis of how to avoid exchange-rate traps, helping your USD assets grow steadily and securely.
Against the backdrop of global economic uncertainty, the US dollar has become an essential part of asset allocation thanks to its dominant position and safe-haven attributes. In particular, after the Federal Reserve (Fed) raised interest rates to combat inflation, USD deposit rates surged far above those of the New Taiwan dollar, making USD time deposits an ideal choice for conservative investors.
Different financial tools fit different levels of risk tolerance. The table below helps you quickly identify the option that best matches your needs:
| Investment Tool | Expected Return |
Risk Level |
Suitable For |
| USD Time Deposit | Medium (higher than TWD deposits) | Low (mainly exchange rate risk) | Conservative investors seeking stable returns and able to tolerate mild currency fluctuations. |
| TWD Time Deposit | Low | Very Low (almost no risk) | Individuals who are extremely risk-averse and require high liquidity. |
| US Stock Investment | High | High (market volatility and currency risk) | Aggressive investors seeking high capital gains and able to accept higher risk. |
To help you compare easily, we have compiled the latest USD time deposit rate offers from multiple banks. Please note that banks frequently update their promotional rates, so the actual rates are subject to each bank’s official announcement. The table below is an illustrative example to show you the comparison structure.
Short-term plans are ideal for investors who want to earn higher interest over a short period while maintaining greater liquidity. Many banks launch limited-time high-interest offers for new funds or designated customer segments.
| Bank | 3-Month Rate (Annualized) | 6-Month Rate (Annualized) | Minimum Deposit Amount | Notes |
| Bank A | ~5.2% | ~5.0% | USD 5,000 | New funds promotion |
| Bank B | ~5.1% | ~4.9% | USD 10,000 | Digital customers only |
If you have funds that you do not plan to use in the near future, choosing a term of one year or longer allows you to lock in stable returns over an extended period.
Fubon USD time deposits have long been one of the most popular options in the market, and their plans usually have the following features:
Before choosing a plan from Fubon or any other bank, be sure to read the campaign terms carefully and understand the promotional rate period, amount thresholds, and whether the offer must be combined with other financial products.
Although high interest rates are appealing, any foreign currency investment comes with risks. Before committing funds, you must understand the following three key risks of foreign currency time deposits.
This is the core risk of foreign currency time deposits. Suppose you place 10,000 USD when the USD/TWD exchange rate is 1:32 (costing 320,000 TWD). With a 5% annual rate, your principal plus interest becomes 10,500 USD after one year. However, if the exchange rate drops to 1:30 at maturity, converting back gives you only 315,000 TWD. Even though you earned 500 USD in interest, you end up losing 5,000 TWD after conversion. This is exactly what people mean by “earning interest but losing on exchange rates”.
Suggested strategy: Exchange in batches to average out costs, and set clear take-profit and stop-loss levels. You may refer to authoritative sources such as the Bank of Taiwan’s posted exchange rates and keep an eye on exchange rate trends.
As its name suggests, a time deposit locks in your funds for a fixed period. If you unexpectedly need cash before maturity, you must make an “early withdrawal”. Banks typically calculate interest at a discounted rate based on the posted rate (commonly at 80%). If the discounted interest is not enough to cover what you have already received, the bank will deduct the difference from your principal. For this reason, the funds you place in a time deposit should be idle capital that you are certain you will not need during the term.
When you lock your funds in a time deposit, you lose the chance to invest in other assets that may offer higher returns, such as stocks or mutual funds. This is what we call “opportunity cost”. In addition, if USD interest rates are lower than local inflation, your purchasing power still erodes in real terms. Therefore, USD time deposits are more suitable as the “stable” portion of your asset allocation, rather than the core vehicle for pursuing high returns.
With so many options available, how do you identify the one that suits you best? Follow the four steps below to help you make an informed decision.
Start by asking yourself: When will you need to use this money? If there is a chance you might need it within a year, consider shorter-term options such as 3-month or 6-month deposits. If the funds will remain idle for a longer period, you may choose a one-year or longer term to lock in a higher interest rate.
Don’t look only at the headline rate! Details matter. You should compare the following:
Most banks now encourage customers to use online channels. Exchanging currency through online banking or mobile apps usually provides better rates than over-the-counter transactions (for example, a 0.03–0.05 reduction in spread). Setting up time deposits online is also more convenient and may even come with additional rate bonuses. Factoring in these benefits can effectively lower your exchange costs and increase your overall return.
A: Yes. For Taiwan tax residents, overseas interest income is considered part of overseas income. If the total overseas income within one filing household exceeds 1,000,000 TWD, the full amount must be included in the basic income calculation. However, since the basic income has an exemption of 6,700,000 TWD, small deposit interest amounts usually do not incur tax unless you belong to a high-income group.
A: This is one of the advantages of time deposits. Once you commit to a fixed-rate time deposit, your interest rate is “locked in” for the entire term. Even if market rates fall later, your deposit will continue to earn interest at the original higher rate until maturity. Conversely, if your plan uses a floating rate, it will be affected by rate cuts.
A: This depends on your view of exchange-rate trends and your tolerance for risk. If you believe the current rate is already at a relatively low level and you expect it to rise, you may consider a “lump-sum” conversion to secure your cost. However, if you are unsure or want to avoid the risk of buying at the peak, “exchanging in batches” (similar to dollar-cost averaging) is a more stable strategy that helps smooth out your conversion cost and reduce single-point exchange-rate risk.
A: Requirements vary by bank. Generally, over-the-counter applications have thresholds ranging from 1,000 USD to 5,000 USD. For special high-interest promotional offers, the minimum can be much higher such as 10,000, 20,000, or even 100,000 USD. It is recommended to check the latest terms of the specific bank you intend to use.
In summary, when choosing a USD time deposit, you should not be swayed solely by short-term high interest rates. It is essential to evaluate your own risk tolerance and capital planning comprehensively. The USD time-deposit rates compiled in this article can serve as a starting point for your decision-making, especially the plans offered by major banks such as Fubon USD time deposits, which are worth noting for their stability and promotional benefits. Before committing funds, be sure to factor in the risks of foreign-currency deposits particularly the impact of exchange-rate volatility so you can earn your desired returns in a steady and controlled manner.
