USD/KRW Exchange Rate History
A decade of US Dollar–South Korean Won movements, with the events that drove them.
USD/KRW 10-year snapshot
USD/KRW currently sits roughly 96% through its 10-year range — near the upper end, with the rate at decade-high levels.
The last decade in USD/KRW
USD/KRW is one of Asia's most-traded emerging-market currency pairs — heavily linked to Korean technology exports (Samsung, SK Hynix, Hyundai), semiconductor cycles, and global risk sentiment. Over 2016–2026, USD/KRW traded between 1,090 (early 2018 KRW strength) and 1,440 (October 2022 USD peak). The Bank of Korea manages KRW with a relatively light touch — accepting volatility rather than burning reserves to defend specific levels.
Long-term trend
Gradual KRW depreciation against USD over the past decade. USD/KRW has moved from a 1,000-1,100 range (early 2010s) to 1,300-1,400+ range (2022-2025), reflecting Fed-BoK rate divergence cycles and Korean economy slowdown. The KRW is unusually sensitive to global tech-cycle data — semiconductor demand, smartphone shipments, and Chinese consumer data all move KRW meaningfully. The pair is highly liquid and serves as a benchmark for broader Asian-EM sentiment.
Key events
USD/KRW at multi-year low
KRW reached multi-year highs against USD as global risk-on flows favored Korean tech exports and the BoK held rates while the Fed normalized. The pair hit 1,054 — strongest KRW since 2014.
USD/KRW fell from 1,100 (early 2018) to 1,054 (April 2018).
COVID won crash
The COVID panic combined with global tech-export uncertainty drove USD/KRW to crisis-era highs above 1,290. BoK's emergency rate cuts and Fed dollar swap-line support stabilized the pair within weeks.
USD/KRW rose from 1,170 to 1,290 in March 2020, then settled to 1,090 by January 2021.
USD/KRW hits 1,440 — multi-year high
Aggressive Fed tightening combined with Korean tech-export weakness drove USD/KRW above 1,440 — the highest since the 2009 financial crisis. BoK rate hikes to 3.50% partially offset but couldn't reverse the trend.
USD/KRW peaked at 1,444 in October 2022, then settled below 1,300 by mid-2023.
KRW under pressure on tech cycle + politics
Combination of US-China semiconductor restrictions affecting Korean exports, BoK-Fed rate gap, and political uncertainty (Yoon impeachment scenarios) drove USD/KRW back to 1,400 levels.
USD/KRW rose from 1,330 (January 2024) to 1,420 (April 2024).
Yoon martial-law declaration shock
President Yoon Suk Yeol's brief 6-hour martial-law declaration on December 3, 2024 triggered the largest single-day USD/KRW spike in years. KRW recovered after the declaration was rescinded but uncertainty around Yoon's impeachment kept the pair elevated for weeks.
USD/KRW spiked from 1,402 to 1,442 overnight, then settled to 1,460+ over the following weeks.
BoK eases as semiconductor cycle stabilizes
BoK cut rates 100bp through 2025 as Korean inflation fell to target and global semiconductor demand stabilized. USD/KRW consolidated in a 1,350-1,400 range.
USD/KRW traded 1,350-1,400 through late 2025.
Practical takeaway
For Koreans traveling abroad (or international visitors to South Korea), USD/KRW's volatility is unusually tied to global tech-export cycles and Korean political events. Watch semiconductor industry data, Chinese consumer trends, and BoK monetary policy meetings. The pair has settled into a 1,300-1,450 range that's historically weak for KRW — making Korea relatively affordable for foreign visitors compared to 2018 levels.

Frequently asked questions
Why is the Korean Won so volatile?
Korean Won volatility is driven by: high sensitivity to global tech-export cycles (semiconductors, smartphones), Korean equity-market flows (foreigners hold ~30% of KOSPI), persistent foreign-investor activity, and political risk episodes. The combination produces larger USD/KRW daily moves than most other Asian-EM pairs. Korean carry trade is also material — KRW serves as a regional carry currency.
How does the BoK manage USD/KRW?
The Bank of Korea (BoK) intervenes selectively to smooth volatility rather than defend specific levels. BoK's FX reserves of $400B+ provide substantial intervention capacity but are deployed sparingly. BoK rate policy typically tracks Fed cycles with 25-50bp differentials, and verbal intervention through governor speeches is common during stress episodes.
What was the December 2024 USD/KRW shock?
On December 3, 2024, President Yoon Suk Yeol declared martial law in response to a parliamentary deadlock — a stunning move that lasted only 6 hours before parliament forced its withdrawal. USD/KRW spiked 40 won (3%) overnight, the largest single-day move in years. The political crisis that followed (impeachment proceedings, constitutional court referral) kept USD/KRW elevated above 1,440 for weeks.
