If you checked your banking app this week and Korea suddenly looked a little pricier, you are not imagining it. On October 16, 2026, the Korean won jumped to its strongest level against the US dollar in about two years.
The dollar closed at 1,331.4 won in Seoul's daytime session, down 13.2 won from the previous day, according to Korean news agency News1. That is great news for people paid in won. For you, holding dollars, it means each dollar buys a bit less bibimbap.
So how much does it really change your trip? Less than the headlines suggest, but enough that a few smart payment habits now matter more. Let's run the numbers.
At a Glance
- On Oct 16, 2026, $1 bought 1,331.4 won, down from 1,344.6 won a day earlier.
- A stronger won means your Korea trip costs slightly more in dollars, about 1% in this one-day move.
- On a ₩1,500,000 trip, that is roughly $11 more. Real, but small.
- Bigger savings come from how you pay: always choose KRW on card machines and ATMs, and avoid exchanging lots of cash at the airport.
What "a Stronger Won" Actually Means
An exchange rate is just a price: how many won one US dollar can buy.
When that number goes down, the won is getting stronger. On October 15 the closing rate was 1,344.6 won per dollar (News1 reported the Oct 16 close of 1,331.4 as 13.2 won lower). On October 16, the same dollar bought 13.2 fewer won.
Prices in Korea did not change overnight. A bowl of naengmyeon (냉면, cold noodles) still costs the same number of won. What changed is how many dollars you need to get those won.
News1 linked the move to easing worries about further US monetary tightening, which pushed US interest rates and the dollar lower. That is the "why" for today. We won't guess where the rate goes next, and neither should anyone selling you a currency product.
Let's Do the Math: A Sample 5-Day Seoul Trip
Here is a simple sample budget in won. These amounts are illustrations, not quoted prices. Swap in your own numbers.
| Item | Budget (KRW) | At 1,344.6 (Oct 15) | At 1,331.4 (Oct 16) | Difference |
|---|---|---|---|---|
| Lodging (4 nights, mid-range) | ₩600,000 | $446.23 | $450.65 | +$4.42 |
| Food & cafés | ₩300,000 | $223.11 | $225.33 | +$2.21 |
| Local transport | ₩100,000 | $74.37 | $75.11 | +$0.74 |
| Shopping (K-beauty, souvenirs) | ₩400,000 | $297.49 | $300.44 | +$2.95 |
| Tickets & activities | ₩100,000 | $74.37 | $75.11 | +$0.74 |
| Total | ₩1,500,000 | $1,115.57 | $1,126.63 | +$11.06 |
Market (interbank) closing rates from News1. Your bank or card network will use its own rate, usually a little worse.
So the one-day move added about $11 to a ₩1.5 million trip. For a couple spending ₩3,000,000, it is roughly $22.
Now compare that with payment mistakes. If a card terminal converts your bill into dollars on the spot (more on this below), you pay the provider's rate plus any fees it adds. As an illustration only, a 3% difference on ₩1,500,000 is about $34. That is three times today's currency move.
Here's the takeaway: you can't control the exchange rate, but you can control how you pay.
Buying Korean Goods From Abroad
The same logic applies if you order K-beauty products, albums, or snacks from Korean online shops.
A ₩45,000 skincare set cost about $33.47 at the Oct 15 rate and about $33.80 at the Oct 16 rate. A difference of 33 cents.
A ₩15,000 album went from about $11.16 to $11.27. You will probably not notice it on a single order. Shipping fees, import duties in your country, and your card's foreign transaction fee usually matter far more than a day's rate change.
Tip: if a Korean shop lets you pay in won or in your home currency, the won option combined with a no-foreign-fee card is usually the cleaner deal. Check your card's terms first.
Exchanging Money in Korea: Where It Makes Sense
You don't need a big pile of cash in Korea. Cards work almost everywhere, from convenience stores to taxis. Still, a little cash helps for street food stalls, traditional markets, and topping up a transit card.
Airport exchange counters are run by banks and are convenient when you land; according to the Seoul Metropolitan Government, hours vary and some operate 24/7. Rates differ from counter to counter, so many travelers change only a small amount there, enough for the first day, and compare posted rates in the city for the rest.
Bank branches in the city exchange foreign currency at posted rates. Bring your passport: Seoul's official English site says a passport or residence card is required to exchange currency. VisitKorea notes that banks are generally open 09:00–16:00 on weekdays (hours vary by bank and region), so they are not an option in the evening or on weekends.
Authorized private exchange offices are another option, and you will see many in busy tourist areas such as Myeongdong (명동). VisitKorea advises exchanging at a bank or an authorized exchange service center, and Seoul's official site says most private offices keep longer hours than banks (check each branch). Rates vary, so compare the posted rate at two or three counters before you hand over cash, and stick to authorized businesses.
A simple rule: change a little at the airport, the rest in the city, and lean on cards for everything else.

Paying by Card: Always Choose KRW
This is the single most useful habit for your trip.
Some card terminals and ATMs offer to charge you in your home currency instead of won. This is called dynamic currency conversion (DCC). In plain words: the shop's payment provider converts the price for you, using its own exchange rate, and often adds a markup.
It looks helpful because you see a familiar dollar figure, but it comes with the provider's exchange rate and fees. Visa says merchants and ATMs must give you the choice and must not choose for you, and recommends declining if you feel pressured. Mastercard's consumer FAQ says the best practice is to decline the conversion and let your own bank do it.
What to do:
- When the screen asks "USD or KRW?", choose KRW (won).
- If a cashier asks, say "Won, please."
- Check your receipt. If it shows a dollar amount and a "conversion rate," DCC was applied. You can ask to cancel and re-run it in won.
Also check whether your card charges a foreign transaction fee (often a few percent per purchase). A card with no such fee is worth setting up before you fly.
ATM Tips for Foreign Cards
Not every ATM in Korea accepts foreign cards. Look for machines labeled "Global ATM" or showing the logos of the international networks on your card. Availability varies by location, so it is wise to have a backup card. Note that Seoul's official English site says bank ATMs may be unavailable roughly between 10 PM and 8 AM.
A few habits keep costs down:
- Decline conversion at the ATM too. If it offers to bill you in dollars, choose won.
- Withdraw fewer, larger amounts. Many ATMs and home banks charge a flat fee per withdrawal.
- Know your daily limit before you travel, both your bank's and the machine's.
- Tell your bank you're traveling if it requires that, so your card isn't blocked.
Small Habits That Matter More Than the Rate
Think of the exchange rate as the weather. You can't change it, but you can dress for it.
First, budget in won. Korean prices are set in won, so write your plan that way and convert at the end. That keeps you from being surprised at the register.
Second, use a rechargeable transit card for subways and buses instead of buying single tickets. It saves time and small amounts add up over a week.
Third, look into tourist tax refunds when you shop. Many stores in tourist areas offer tax-free shopping for eligible foreign visitors who spend above a minimum amount. Ask the store and keep your passport handy. Rules and thresholds change, so check the latest conditions before you shop.
Finally, track your spending in your card app as you go. If a charge ever shows up in dollars instead of won, you'll catch the DCC problem on day one, not after you get home.
Cash vs Card vs ATM: Quick Comparison
| Option | Good for | Watch out for |
|---|---|---|
| Airport exchange | A small amount on arrival | Hours and rates vary; compare |
| City bank branch | Larger amounts, posted rates | Weekday hours; passport needed |
| Licensed money changer | Competitive rates in tourist areas | Compare counters; use licensed shops |
| Card in KRW | Most daily spending | Foreign transaction fees; DCC prompts |
| Global ATM | Cash top-ups | Per-withdrawal fees; decline conversion |

Q
Q. Is Korea now expensive for American travelers?
Not dramatically. The one-day move on Oct 16 was about 1%. On a typical trip, that's a few dollars to a few tens of dollars.
Q. Should I wait for a better exchange rate before booking?
We can't tell you where the rate will go, and no one can reliably. Plan with today's rate and add a small buffer to your budget.
Q. Is it better to pay in dollars or won on a Korean card machine?
Won. Paying in dollars triggers dynamic currency conversion, which lets the merchant set the exchange rate and can add a markup; Visa and Mastercard both suggest declining it.
Q. Do I need cash in Korea?
A little. Cards are widely accepted, but some market stalls and street vendors prefer cash.
Q. Can I use any ATM?
No. Look for ATMs that accept foreign cards, often marked "Global ATM," and decline any offer to convert to your home currency.
