The South Korean won (KRW) is more than just a currency—it’s a symbol of resilience, innovation, and cultural pride. Whether you're planning a trip to Seoul, sending money to family in Busan, or simply curious about global economies, understanding the won offers valuable insights into one of Asia’s most dynamic nations. From its linguistic roots to cutting-edge security features, the won reflects South Korea’s journey from post-war recovery to technological powerhouse.
This deep dive explores six compelling aspects of the South Korean won, blending history, economics, and modern finance to give you a well-rounded perspective—perfect for travelers, investors, and culture enthusiasts alike.
Etymology: The Shared Roots of "Won," "Yuan," and "Yen"
The word "won" traces back to the Chinese term yuan, meaning “round” or “circular,” originally referring to the shape of ancient coins. This same root gave rise to Japan’s yen and China’s yuan, highlighting the interconnected monetary histories of East Asia.
When Korea introduced the won in 1902 during the Korean Empire, it adopted this widely recognized term, aligning with regional financial practices. Although the currency was later replaced during Japanese colonial rule (1910–1945), the name returned after liberation—a nod to Korea’s cultural continuity and economic sovereignty.

Banknotes That Honor National Icons
South Korean banknotes don’t just carry value—they tell stories. Each denomination features a prominent historical figure, celebrating intellectual legacy and national identity.
- ₩1,000 note: Features Yi Hwang, a revered Confucian scholar whose teachings shaped Korean philosophy.
- ₩5,000 note: Depicts Yi I, another leading Confucian thinker and statesman known for his ethical governance.
- ₩10,000 note: Honors King Sejong the Great, creator of Hangul, the Korean alphabet. His contribution to literacy and science makes him a national hero.
- ₩50,000 note: Showcases Shin Saimdang, a talented artist and calligrapher, and mother of Yi I. She represents the often-overlooked role of women in Korean history.
These figures are more than faces on paper—they’re symbols of knowledge, innovation, and cultural pride. The inclusion of Shin Saimdang marked a milestone as the first woman (other than royalty) to appear on a modern South Korean banknote.
Cutting-Edge Security Features Against Counterfeiting
In the early 2000s, South Korea faced a surge in counterfeit ₩5,000 notes, prompting a major redesign of its currency. The response? Some of the most advanced anti-fraud technology in circulation today.
Modern South Korean banknotes include:
- Color-shifting 3D holograms that move and change hue when tilted.
- High-resolution watermarks showing lifelike portraits.
- Microprinting—tiny text visible only under magnification.
- Optically variable ink that shifts color depending on viewing angle.
Even coins are engineered with security in mind, using specialized alloys and edge designs to prevent duplication. These innovations reflect South Korea’s broader commitment to technological excellence and financial integrity.

Economic Pressures Led to Changes in Coin Materials
Currency isn’t just about design—it’s shaped by economics. Take the humble ₩1 coin: originally made of brass, it became too costly to produce when metal prices rose in 1968. The solution? Switch to aluminum, a lighter and cheaper alternative.
This shift wasn't unique to Korea but reflected a global trend where nations adjusted coin composition based on material costs. While the ₩1 coin is now rare in daily use due to inflation, its evolution illustrates how even small denominations respond to macroeconomic forces.
Today, higher-value coins like ₩10, ₩50, ₩100, and ₩500 remain in active circulation, crafted from durable alloys designed for longevity and ease of use in vending machines and public transit systems.
A Currency Shaped by War, Occupation, and Recovery
The won’s history mirrors South Korea’s turbulent 20th century. Its evolution reveals how politics and conflict can reshape an economy.
- During Japanese occupation (1910–1945), the Korean yen was used—essentially a colonial version of Japan’s currency.
- After liberation in 1945, the first iteration of the won was introduced at an initial rate of 1 USD = 15 KRW.
- The Korean War (1950–1953) triggered hyperinflation and multiple redenominations.
- In 1950, the Bank of Korea was established to stabilize monetary policy.
- By 1975, the won became the sole legal tender under the KRW system still used today.
Each transformation marked a step toward economic independence and resilience. Despite setbacks, South Korea emerged as an export-driven economy—earning the nickname “Miracle on the Han River.”
The Bank of Korea: Steward of Stability
Central to the won’s stability is the Bank of Korea (BOK), founded in 1950 as the nation’s central bank. It succeeded the Bank of Joseon and took full control over issuing currency and managing monetary policy.
The BOK plays a critical role in:
- Controlling inflation through interest rate adjustments.
- Managing foreign exchange reserves.
- Ensuring price stability and financial system integrity.
Its policies have helped South Korea weather global crises—from the 1997 Asian financial meltdown to post-pandemic market volatility. Today, the BOK continues to monitor digital currency trends, including potential central bank digital currency (CBDC) development.
Understanding the Won’s Value in Today’s Economy
South Korea’s rapid industrialization from the 1960s to 1990s strengthened the won significantly. However, recent years have seen fluctuations influenced by global trade dynamics, U.S. monetary policy, and regional geopolitics.
As of mid-2025, 1 US dollar trades at approximately 1,386.6 KRW, reflecting a strengthening trend driven by strong tech exports and stable economic performance. Analysts watch the won closely as a barometer for Asian market sentiment.
For travelers and senders alike, monitoring exchange rates through trusted financial sources can lead to smarter decisions—and better value.
What Denominations Are Available in South Korean Currency?
South Korea uses four primary banknote denominations:
- ₩1,000
- ₩5,000
- ₩10,000
- ₩50,000
And four coin types:
- ₩10
- ₩50
- ₩100
- ₩500
While higher-denomination notes dominate daily transactions, smaller coins are essential for precise pricing and automated systems.
Is the South Korean Won Accepted Outside South Korea?
No, the won is generally not accepted outside South Korea. Most international businesses and airports do not exchange or accept KRW unless specifically serving Korean markets. Travelers should convert leftover won before departure or use reputable exchange services upon return.
How Can I Get the Best Exchange Rate When Converting to Won?
To maximize value:
- Compare rates across banks and licensed exchange providers.
- Avoid airport kiosks, which often offer less favorable terms.
- Use online platforms with transparent fee structures.
- Monitor trends via financial news outlets or currency apps.
Timing matters—exchange rates fluctuate daily based on global economic indicators.
Can I Use Credit Cards Widely in South Korea?
Yes. Major credit cards (Visa, Mastercard) are widely accepted in cities like Seoul, Incheon, and Busan. However, smaller shops or rural areas may prefer cash. ATMs at banks and convenience stores support foreign cards—just ensure your bank allows international withdrawals.
Why Is King Sejong on the Highest-Denomination Note?
Though not on the ₩50,000 bill (which features Shin Saimdang), King Sejong appears on the ₩10,000 note—the second-highest value—as a tribute to his foundational impact. By creating Hangul, he democratized literacy and education, making him one of Korea’s most revered historical figures.
Are There Plans for Digital Won Development?
The Bank of Korea has been researching a central bank digital currency (CBDC) since 2021. While no official launch date has been set, pilot programs suggest South Korea is preparing for a potential digital version of the won—aligning with global trends in digital finance.
