Korean Won (KRW): A Complete Currency Profile
The Korean Won (KRW, ₩) is the official currency of South Korea and one of Asia's most actively traded currencies outside the major reserve currencies. If you're traveling to Seoul, paying a Korean supplier, or just curious why ₩1,000,000 sounds like a lot but is really about $720, this profile covers what you need to know.
A brief history
The modern won was introduced in 1962, replacing the older hwan at a rate of 10 hwan = 1 won. For decades the won was tightly pegged to the US dollar, but after the 1997 Asian Financial Crisis Korea moved to a managed floating exchange rate. The currency took a sharp hit during that crisis and again in 2008 — both episodes still shape how the Bank of Korea thinks about FX volatility today.
The Bank of Korea
The Bank of Korea (BOK) is the country's central bank, founded in 1950. Like most modern central banks, it targets inflation (currently around 2%) and adjusts its base rate to manage growth and prices. Unlike the US Federal Reserve, the BOK is more openly active in FX markets — it intervenes when the won moves too fast in either direction, both to protect Korea's export-heavy economy and to manage capital flows.
Korea also maintains partial capital controls, which is one reason why the won trades at slightly different prices onshore (in Seoul) versus offshore (in non-deliverable forward markets in Hong Kong and Singapore). This same friction is what historically created the Kimchi Premium in Bitcoin markets.
KRW vs USD: long-term trends
Over the past 20 years, USD/KRW has mostly traded between 1,000 and 1,400 won per dollar, with brief spikes during global crises. The won tends to weaken when global risk appetite falls (a "risk-off" currency) and strengthen when Korean exports — semiconductors, autos, ships — are booming. Tech cycles, especially memory chip prices, move the won meaningfully.
Why the numbers look so big
A coffee in Seoul costs around ₩5,000. A nice dinner might be ₩50,000. A mid-range hotel night could be ₩150,000. The numbers feel huge to first-time visitors, but the won simply has a smaller unit value — there are no decimals because no one transacts in fractions of a won. The smallest coin in regular use is the ₩10 piece, and even ₩10 and ₩50 coins are increasingly rare as Korea moves toward a cashless society.
A useful mental shortcut: drop the last three zeros and you're roughly in US dollars. ₩5,000 ≈ $5 (actually closer to $3.60 at today's rates, but it's a fast first approximation). For exact numbers, the xchangepro.app converter handles KRW with the proper zero-decimal formatting.
Tips for tourists exchanging to KRW
- Don't exchange at the airport. Incheon's currency kiosks have some of the worst rates in Korea. Grab a small amount for the train into the city and exchange the rest later.
- Use a no-FX credit card for almost everything. Card acceptance is near-universal in Seoul, including small restaurants and street markets. Cash is increasingly optional.
- For cash, head to Myeongdong. The money changers in Myeongdong (especially around the central streets) consistently offer the best rates in the country — often within 0.3-0.5% of the mid-market rate. Bring USD or EUR cash for the best exchange.
- ATMs work but be picky. Use "Global ATMs" at major banks (KB, Shinhan, Woori) or in convenience stores — they reliably accept foreign cards. Withdraw larger amounts to spread the flat fee.
Korean fintech: the Toss and Kakao Pay era
Korea is one of the most digitally advanced payment markets in the world. Two domestic super-apps dominate everyday money:
- KakaoPay — built on top of KakaoTalk (the messenger 90%+ of Koreans use), it handles payments, P2P transfers, bill pay, and increasingly investing and insurance.
- Toss — a fintech that started as a P2P payment app and expanded into banking (Toss Bank), brokerage (Toss Securities), and insurance. Toss is now one of Korea's largest financial brands.
Both are essentially closed to foreigners without a Korean ID number and Korean bank account, so they're not practical for short-term visitors — but they're the reason cash usage in Korea is collapsing faster than almost anywhere else. If you're staying long-term, opening a Korean bank account and getting onto Toss or KakaoPay will dramatically simplify daily life.
The takeaway
KRW is a stable, well-managed currency in one of the world's most cashless societies. For travelers: use a no-FX credit card by default, keep a small amount of won for the rare cash-only spots, and exchange in Myeongdong if you need more. For everyone else, just remember the "drop three zeros" trick and use a proper mid-market reference rate before any meaningful conversion.
