Korean won for foreign investors comes down to one route with two accounts at each end. Your foreign currency goes into an account in your name at a Korean bank, becomes won, buys the shares, and settles two trading days later. Dividends and sale proceeds come back in won. When you leave, you sell the won for foreign currency and send it out.
The rulebook calls these accounts investment-dedicated accounts, and this guide calls them investment-only accounts. Several dated items shape the route, and three matter most. Interbank trading in won has run around the clock on weekdays since July 6, 2026. The foreign exchange rulebook text that took effect on November 2, 2026 lists short-term financial products among the uses of idle won. And an offshore won settlement network is planned for full launch in January 2027. Which of these touches you depends on whether you hold shares directly, through an omnibus account, or as ADRs.
Key Takeaways
- The route has two accounts. Article 7-37 of the foreign exchange rulebook lets a foreign investor keep an investment-dedicated foreign-currency account and an investment-dedicated non-resident won account in the investor’s own name.
- Round-the-clock trading is an interbank change. The Ministry of Finance and Economy marked July 6, 2026 as the first day of 24-hour FX trading. Whether your broker gives you a rate overnight is the broker’s decision.
- Idle won has more options. Notice 2026-110, effective November 2, 2026, added funds tied to short-term financial products to the money the won account may take in and pay out.
- Your route decides who does the work. For an omnibus account, the rulebook treats the foreign broker as the foreign investor. For an ADR, the depositary receives the won and normally converts it to dollars before paying you.
- A foreign institution has begun using an offshore won account, per press reports. Woori Bank’s Singapore branch was reported to have opened a won account for an overseas institution on October 29, 2026, and the settlement network’s full launch is planned for January 2027.

1. The route, one trade at a time
Follow one purchase from your bank to a Korean broker and back.
| Step | What happens | Where it’s set out |
|---|---|---|
| 1 | Foreign currency is remitted into your investment-only foreign-currency account. | Rulebook Article 7-37 |
| 2 | The foreign currency is sold for won into your investment-only won account. | Rulebook Article 7-37 |
| 3 | The shares are bought and settled two trading days after the trade date. | Financial Services Commission (FSC) |
| 4 | Dividends and sale proceeds arrive in won. | Rulebook Article 7-37 |
| 5 | Won is sold back to foreign currency in your foreign-currency account. | Rulebook Article 7-37 |
| 6 | The foreign currency is remitted out | Rulebook Article 7-37 |
Steps 2 and 5 are where the exchange rate bites, and step 3 is where the calendar does. You’ll want both in mind before you fund anything. Our guide to Korea’s T+2 settlement cycle covers the settlement mechanics.
2. Money in: the two investment-only accounts
Article 7-37 of the foreign exchange rulebook says a foreign investor “may” deposit and dispose of investment funds through two accounts in the investor’s name at a foreign exchange bank. One holds foreign currency. The other holds a non-resident win. The version that’s in force from November 2, 2026, is Ministry of Finance and Economy Notice 2026-110.
Foreign currency can go into the first account when you remit it from abroad or bring it in, or when it comes from another account in your name. It can also come from foreign currency bought with securities sale proceeds, dividends, or interest.
The same clause gives the bank some leeway. Notwithstanding the general rule on when a bank may sell foreign currency (Article 2-3), the bank that sells you foreign currency may check the related transaction records within three business days, counting from the day after the sale.
The won account takes in sale proceeds, dividends, and interest transferred from won accounts at Korean banks and brokers, along with won you bought with the foreign currency in your first account.
3. Converting: what 24-hour trading changes
The ministry’s press release of July 6, 2026, called that day the first day of the launch of the 24-hour FX market. The change is to the interbank market, where banks deal with each other through brokerage platforms. Before it, spot and FX swap trading ended at 2 a.m. Seoul time. The July 2026 joint government roadmap puts the new window at 6 a.m. Monday to 6 a.m. Saturday while the US is on daylight time, and one hour later in US winter time. Weekends and January 1 stay closed.
For you, that matters in two ways. First, the roadmap names the case of an investor who wants to convert after a Federal Open Market Committee press conference, which lands in the Korean small hours. The market wasn’t open at that hour before July 6, 2026. Second, the interbank hours don’t set your hours. Whether your broker or bank quotes you a rate at 3 a.m. is its own decision. The ministry’s materials describe round-the-clock conversion as the aim, but I found nothing in them requiring your broker to offer it. Ask before you plan around it. Our piece on 24-hour won trading covers the market side.
The reference rate is changing too, and that change is already in the rulebook. Notice 2026-88 of July 2, 2026, rewrote the definition of the official daily dollar rate: from January 1, 2027, it becomes a time-weighted average price (TWAP) from a five-minute window around 4 p.m. Seoul time, replacing a weighted average of trades from 9 a.m. to 3:30 p.m. The roadmap calls that rate the basis for accounting, taxation, and trading, so a change in method reaches anyone who converts won amounts at it.
4. After the trade: settlement, dividends, and idle won
The FSC’s glossary says Korean stocks settle both securities and cash two trading days after the trade date. If you fund the purchase yourself, you’ll want the won in place by then. A draft roadmap published by the Korea Exchange and other market bodies on November 2, 2026, as reported by Financial News, would shorten the cycle to T+1 as early as 2028; no final date has been set.
Dividends go the other way. The rulebook lets dividends enter your won account by transfer from a won account at a Korean bank, a broker, or the securities depository. Our guide to collecting Korean dividends covers withholding and the rest of the chain.
Then there’s the one that sits. The July 2026 roadmap named short-term financial products as a second-half 2026 task for the won account. Notice 2026-110 added lines for funds tied to the short-term financial products defined in Article 241 of the enforcement decree of the Capital Markets Act in both Article 7-37(4) and 7-37(5). The rulebook doesn’t say which products your broker offers. That’s the broker’s call, so if you leave money in the account between trades, ask what it can do with it.
5. Money out
Going home is the same route in reverse. Foreign currency bought with won from your won account goes into the foreign-currency account in your name, as Article 7-37(2) sets out. From there the rulebook lets you remit it abroad, move it to another account in your name, or withdraw it in foreign currency.
Taxes aren’t covered here. Dividend withholding is in our dividend guide, and gains are in our guide to Korea’s capital gains tax for foreign investors.
6. Who does the work on your route?
You won’t touch every step on every route.
| Route | Who holds the Korean accounts? | What you deal with |
|---|---|---|
| Direct account in Seoul | You | All six steps, through your Korean broker and bank |
| Omnibus account | Your foreign broker | Your broker’s conversion and fee schedule |
| ADRs | The depositary | Dollars, normally; the depositary receives the won. |
For the omnibus route, Article 7-36 says that when a foreign investor invests through a foreign investor omnibus account, the foreign financial firm that opened it counts as the foreign investor under the rulebook. That’s why the Korean-side accounts and steps are the firm’s, and what reaches you is likely to be its conversion and its fee schedule. Ask for both in writing, since you’ll want it on record. Our explainer on Korea’s omnibus account rules covers the account itself.
For ADRs, the depositary receives the won and normally converts it to dollars before paying you. Our guides to how Korean ADRs work and to how an ADR dividend reaches you follow that route, and our comparison of four routes into Korean stocks helps you choose. If you’re going direct, our guide to opening a Korean brokerage account as a non-resident covers the account.
A separate set of changes is planned for investors who wouldn’t want to open a Korean account at all. Under the July 2026 roadmap, you wouldn’t need a Korean account to hold won. You could keep it at an overseas institution registered with the ministry and trade it with other foreigners without a prior filing, except for domestic real estate. Part of it already sits in the rulebook: Notice 2026-103 of September 16, 2026, added an Article 7-48 item that drops the filing for non-residents who use a registered overseas won institution, and that item has been in force since September 16, 2026. The ministry’s list dated October 7, 2026 shows ten such institutions, all overseas branches or units of four Korean banks. The settlement network behind them was reported to have started a pilot on September 21, 2026, with full launch planned for January 2027.
A ministry draft FAQ, posted on October 1, 2026, says a client of such an institution wouldn’t need to open an investment-only won account in Korea. It’s a draft, and the details can still change. Press reports say the first such transaction at a bank, made by an overseas institution through Woori Bank’s Singapore branch, took place on October 29, 2026. The settlement network’s full launch is planned for January 2027.
