Recently, I've noticed more and more people around me exchanging yen, not just for traveling abroad, but also considering yen for investment allocation. I'm also a bit curious—is it really worthwhile to exchange for yen now, and what are the ways to minimize the costs?

Speaking of which, the Japanese yen is indeed somewhat special in Taiwan. Besides travel expenses (many places in Japan still only accept cash), there are also significant demand for purchasing agents and studying abroad. But what's even more interesting is that the yen itself is one of the world's three major safe-haven currencies, alongside the US dollar and Swiss franc. When the market is turbulent, funds tend to flow into the yen for safety. For Taiwanese investors, exchanging for yen isn’t just for leisure; it can also hedge against Taiwan stock market risks. Plus, Japan has maintained ultra-low interest rates for a long time, creating opportunities for interest rate arbitrage, which is why more and more people are considering yen as part of their asset allocation.

So, is exchanging for yen worthwhile now? Honestly, the exchange rate has been fluctuating, but compared to the beginning of the year, the yen has appreciated quite a bit, making the gains from exchanging yen quite substantial. The key is how to exchange to keep costs as low as possible. I’ve summarized four mainstream methods, each with its pros and cons.

The first is the most traditional in-person currency exchange, where you go to a bank or airport to exchange cash for yen. The advantage is safety and full denomination options, but the obvious downside is the exchange rate spread (about 1-2% above market price), plus possible handling fees. Exchanging 50k TWD might result in a loss of 1,500 to 2,000 TWD. I recommend this method only for urgent, temporary needs, like needing some cash at the airport.

The second is online currency exchange followed by cash withdrawal. Using a bank app or online banking to convert TWD into yen and deposit into a foreign currency account offers better rates (about 1% better than cash selling rate), but you’ll pay a fee when withdrawing cash. This method is suitable for those experienced in forex investing, allowing for staggered entry to average costs, with costs around 500 to 1,000 TWD.

The third is online currency settlement, which doesn’t require opening a foreign currency account. You simply fill in the amount and branch on the bank’s website, then pick up the cash at the branch. Taiwan Bank’s “Easy Purchase” online settlement often waives handling fees, and the exchange rate is favorable. I highly recommend this method, especially if you plan ahead and want to withdraw directly at the airport. The cost is roughly 300 to 800 TWD, and pre-booking makes it very convenient before traveling.

The fourth is ATM cash withdrawal in foreign currency, available 24/7. It deducts directly from your TWD account with only a 5 TWD interbank fee. The downside is limited locations, fixed denominations, and potential cash shortages during peak times. Costs are about 800 to 1,200 TWD, suitable for urgent needs when you don’t have time to visit a bank.

If your budget is between 20k and 50k TWD, I recommend a mixed approach of “online currency settlement plus foreign currency ATM withdrawal,” which is the most cost-effective. For example, settle online for 10k–20k TWD, then pick up at the airport or branch, and use ATMs for additional needs.

Currently, the exchange rate is about 4.85 to 4.87 yen per TWD. With 20,000 TWD, you can get roughly 97,400 yen at the spot rate. However, selling cash at the bank’s selling rate will yield slightly less, with a difference of a few hundred yen. It seems small, but for larger amounts, this difference becomes quite noticeable.

After exchanging for yen, don’t let your money sit idle. The simplest way is to deposit yen in a fixed deposit account, which offers an annual interest rate of about 1.5% to 1.8%, starting from 10,000 yen. If you want some growth, consider yen ETFs or small-scale forex swing trading. While the yen is a strong hedge, it also fluctuates bidirectionally. The Bank of Japan’s rate hikes support it, but global arbitrage unwinding or geopolitical conflicts could push it down. Therefore, staggered entry and diversified allocation are more prudent.

In summary, the yen is no longer just “pocket money” for travel; it’s an asset with both hedging and investment value. By following principles of staggered exchange and not sitting on your gains, you can minimize costs and maximize returns.
