The South Korean won is currently at its weakest point in nearly two decades. As of this writing, the won-to-rupiah exchange rate hovers around Rp11.2–11.6 per 1 won, meaning 10,000 won that was worth Rp120,000 a year ago is now only around Rp113,000–116,000. For travelers who've been eyeing a Korea trip for a while, this is a rare moment worth seizing.
March Exchange Rate: How Weak Is the Won in 2026?
According to data from Trading Economics and Investing.com, the Korean won exchange rate against the US dollar broke through the psychological level of 1,500 won per dollar in mid-March 2026—the weakest level since March 2009. The average rate throughout 2026 sits around 1,454–1,459 won per dollar, far weaker than the 2024 average which hovered in the 1,350s.
The impact is felt directly on the won-to-rupiah rate. A year ago, 1 won was worth around Rp12, while as of March 2026 the won-to-rupiah rate moves in the Rp11.2–11.6 range. This difference may look small per unit, but when calculated for total expenses on a 5–7 day Korea trip—which typically costs 1–2 million won—the savings can reach hundreds of thousands to over one million rupiah.
Why Is the Won This Weak in 2026?
Several structural and geopolitical factors are simultaneously putting pressure on the won's value.
Massive Capital Outflows
According to analysis from EBC Financial Group and The Korea Herald, one of the main causes of the won's weakness is the massive investment flow from Korean citizens into foreign assets, particularly US tech stocks. The Bank of Korea recorded foreign securities investment reaching USD994.3 billion, exceeding foreign investment in Korea for the first time.
Geopolitical Tensions and Energy Prices
The escalation of Middle East conflicts in March 2026 pushed Brent oil prices past USD100 per barrel. South Korea, which heavily depends on energy imports, was directly impacted according to Trading Economics data. Dollar demand surged for import payments, pushing the won even lower.
Interest Rates and The Fed's Policy
The Bank of Korea maintained interest rates at 2.50% as of February 2026, while US rates remain higher. According to The Korea Times, this interest rate gap has driven capital to continuously flow out of Korea since 2022—a structural trend showing no signs of reversing.
Tariff Concerns and Trade War
According to Business Korea, the US Section 301 investigation into Korean trade practices adds uncertainty for Korean exporters. Unlike the Japanese yen and euro which strengthened against the dollar, the won actually weakened more than 1% since Trump's inauguration, making it one of the weakest major currencies in 2026.
What Does This Mean for Travelers Heading to Korea?
With the won-to-rupiah rate weakening, your rupiah's purchasing power in South Korea automatically increases. A bowl of bibimbap at a local restaurant that usually costs 9,000 won is now only around Rp101,000 compared to Rp108,000 a year ago. A portion of tteokbokki in Myeongdong priced at 5,000 won is now equivalent to Rp56,000. Savings per transaction may look small, but the accumulation over a week-long holiday is significant.
Here's a rough cost comparison simulation:
- Lunch at a local restaurant (10,000 won): 2025 ≈ Rp120,000 → 2026 ≈ Rp113,000
- Gyeongbokgung Palace entrance ticket (3,000 won): 2025 ≈ Rp36,000 → 2026 ≈ Rp34,000
- Daily T-Money top-up (7,000 won): 2025 ≈ Rp84,000 → 2026 ≈ Rp79,000
- Souvenir shopping in Myeongdong (100,000 won): 2025 ≈ Rp1,200,000 → 2026 ≈ Rp1,130,000
- Total spending of 1 million won: 2025 ≈ Rp12,000,000 → 2026 ≈ Rp11,300,000
For total expenses of 1 million won during your trip, the difference can reach Rp700,000 or more, enough for several meals or a few extra souvenirs.
When Is the Best Time to Exchange Rupiah to Won in 2026?
According to historical data from Exchange-rates.org, the won exchange rate can fluctuate quite widely even within a single month. Throughout 2026, the USD/KRW rate moved between 1,427 (February) to 1,506 (March), a difference of nearly 80 won per dollar. For those exchanging rupiah to won, this fluctuation means a real difference.
Currency exchange tips to consider:
- Monitor the current won-to-rupiah rate regularly before departure—use platforms like Wise, Google Finance, or Investing.com
- Exchange most of your funds when the rate is favorable—don't wait until you're at a Korean airport which usually offers worse rates
- Money changers in Myeongdong and Hongdae areas, Seoul, generally offer more competitive rates than Incheon Airport
- Consider using a multi-currency debit card or e-wallet that applies mid-market rates without large markups
- Prepare some cash in won since many street vendors and traditional markets only accept cash

Tips to Maximize Savings While in Korea
A weak Korean won alone isn't enough, smart spending strategies can save you even more.
- Make the most of Seoul's efficient and cheap subway—avoid taxis unless absolutely necessary
- Many iconic tourist spots in Seoul are free: Bukchon Hanok Village, Cheonggyecheon Stream, Gwanghwamun Square, and the Han River area
- Eat at convenience stores (CU, GS25, 7-Eleven) for breakfast and late-night snacks—triangle kimbap and instant ramyeon are super affordable
- Shop for souvenirs at Daiso and Namdaemun Market, not tourist shops in Myeongdong
- Download Naver Map as a replacement for Google Maps which has limited functionality in Korea
- Make sure your internet is ready the moment you land—activate a South Korea eSIM from Global Komunika before departure so you're connected instantly without queuing to buy a SIM at Incheon Airport
- Visit Korea during low season (January–February or November) for cheaper flights and accommodation
Will the Won Keep Weakening?
According to analysis from S&P Global Ratings cited by The Korea Herald, the won is projected as the most vulnerable currency among 16 major currencies monitored by State Street Global Markets throughout 2026. Bank of America estimates the rate could return to 1,395 won per dollar by the end of 2026, but even that is still historically weak.
Factors to monitor:
- Middle East conflict developments and their impact on global energy prices
- Interest rate decisions by The Fed and Bank of Korea in the next quarter
- The ongoing trend of Korean citizens investing in foreign assets
- US tariff policies toward South Korea following the Section 301 investigation
For travelers, the main takeaway is simple: if South Korea is on your dream destination list, 2026 offers purchasing power that rarely happens. A weakening won-to-rupiah rate isn't an economic disaster for travelers—quite the opposite, it's a window of opportunity. Monitor the won rate regularly, prepare your budget, and book tickets early. The streets of Myeongdong, Gyeongbokgung Palace, and a warm bowl of ramyeon on a Hongdae corner await at friendlier prices than ever before.
