Imagine you teach English in Busan and earn 4 million won a month. On July 2, your paycheck was worth about $2,571. By mid-October, the same paycheck was worth roughly $2,989. You did not get a raise. Your boss did not change a thing. The only thing that moved was the Korean won exchange rate.
In the summer of 2026, the won went from its weakest level since the 2008 crisis era to its strongest in two years. On July 1, one US dollar briefly bought 1,559.2 won. On September 9, it bought just 1,336.1 won at the close. That is a swing of more than 200 won in about ten weeks, and a gain of roughly 16% for the won.
For most Koreans, this was a headline. For foreigners living in Korea, it was personal. It changed the value of salaries, rent, savings and money sent home. It also changed how cheap Korea feels to tourists, and how much foreign investors really earned from Korean stocks. Here is what happened, why it happened and what to watch next.
The Korean Won Exchange Rate in 2026: A Timeline
Korean won exchange rate, selected daytime closes, July to October 2026
The year started weak and got weaker. In early February, the won traded near 1,450 per dollar, close to a 17-year low. Then war broke out in the Middle East at the end of February, and oil prices jumped. Korea imports almost all of its energy, so that was bad news for the currency. In March, the won crossed 1,500 for the first time in 17 years, as we reported in our story on Korean won volatility.
The pressure did not ease in spring. The won averaged about 1,466 per dollar in the first quarter and about 1,490 in the second, according to Investchosun. Then came the bottom. On July 1, the won hit 1,559.2 during the session, its weakest level since March 2009. The next day, it ended the daytime session at 1,555.8.
What followed surprised almost everyone. On July 8, the won-dollar exchange rate slipped back below 1,500. By August 19, it closed in the 1,300s for the first time in about 11 months. On September 9, it finished at 1,336.1, the lowest weekly close since October 2024.
The won has held most of those gains since. On October 12, it briefly touched 1,333.2 per dollar, according to SBS. That was its strongest level since October 2024. Two days later, it closed at 1,338.3.
Why the Korean Won Exchange Rate Slumped in the First Half
To understand the rebound, you first need to understand the slump. It was not caused by a weak economy. In fact, Korea was exporting chips at a record pace. That contradiction puzzled many analysts.
The Korea Times explained several reasons in early July. First, foreign investors were selling Korean shares at a record pace. They sold 150.3 trillion won of KOSPI stocks between January and early July, even as the index nearly doubled. When foreigners sell shares, they convert won back into dollars, which pushes the won down.
Second, the dollar itself was strong. The dollar index rose about 3% in the first half as markets stopped expecting US rate cuts. Meanwhile, the Japanese yen fell to its weakest level since 1986. The won tends to move with the yen, so that dragged it down too.
Third, Koreans themselves were buying dollars. Exporters held on to their dollar earnings instead of converting them. Dollar deposits at four major banks rose from $41 billion at the end of March to $48.3 billion in early July. Ordinary investors were sending money abroad as well. Korean retail investors held about $171 billion in overseas stocks by late January. We explored that trend in our report on Korea US stock investors.
Seoul Pushes Back
Officials were alarmed, too. Back in February, US Treasury Secretary Scott Bessent had said the won’s weakness did not match Korea’s strong fundamentals. Seoul pushed exporters to convert more of their earnings into won. It also nudged the National Pension Service to sell dollars. On July 2, Vice Finance Minister Huh Chang called the rate misaligned with the economy and said the government was ready to step in.
By early July, some forecasters had turned very gloomy. Nomura and Kyobo Securities both warned that the won could weaken to 1,600 per dollar. Instead, it turned around within days.
What Turned the Won-Dollar Exchange Rate Around
What weakened and what strengthened the Korean won in 2026
No single event explains the reversal. Rather, several forces lined up at the same time.
A $26.5 Billion Chip Deal
The first trigger was a single company. On July 10, SK hynix priced 177.9 million American depositary receipts on Nasdaq at $149 each. The offering raised about $26.5 billion, roughly 40 trillion won. Crucially, the company planned to spend most of the money in Korea, including on its chip cluster in Yongin. That meant billions of dollars would need to be converted into won.
The Bank of Korea estimated that related dollar inflows could reach up to $30 billion. Traders who had bet on a weaker won rushed to close those positions. As a result, the won gained ground quickly.
Japan Steps In
The second force came from Tokyo. Between July 30 and August 26, Japan spent a record 15.4 trillion yen, about $96 billion, buying its own currency. Before the intervention, the yen had sunk to 163.99 per dollar. By July 31, it had recovered to 157.40. Because the won often follows the yen, Japan’s move helped Korea too.
Exporters Finally Sell Their Dollars
The third force was the end of dollar hoarding. Once the rate started falling, exporters who had been waiting for a better price began selling their dollars. Corporate tax payments in late August added more demand for won.
Export income kept flowing, too. In August alone, exports jumped 68.7% from a year earlier to $98.25 billion. The trade surplus reached $34.75 billion, the third straight month above $30 billion, according to Financial News. On September 9, a Woori Bank researcher pointed to two main forces. In his view, dollar weakness against the yen and steady exporter selling were driving the won higher, Asia Business Daily reported.
The Bank of Korea Raises Rates
Finally, Korean interest rates rose. In July, the Bank of Korea raised its base rate from 2.5% to 2.75%, its first hike since January 2023. It cited inflation of 3.2%, high oil prices and a weaker won. Then, in August, it raised rates again to 3.00%. Higher Korean rates make won deposits more attractive relative to dollar ones.
The Paradox: Foreigners Kept Selling
Here is the strange part. Foreign investors did not come back. In September, they sold another 21.5 trillion won of KOSPI shares, mostly SK hynix and Samsung Electronics. Over five months, their net selling reached about 135 trillion won. Even so, the Korean won exchange rate held near its strongest levels of the year. Simply put, the dollar supply from exporters and corporate deals was larger than the dollar demand from departing investors.
The Yen Cross Rate: The Story Japanese Visitors Are Living
Korean won per 100 Japanese yen, 2026
Most foreign coverage focuses on the won-dollar exchange rate. However, Korea’s second-largest group of visitors comes from Japan. For them, the yen cross rate matters far more.
In late June, 100 yen bought about 954 won. By late August, it bought only about 860 won. On October 12, the rate fell to 845.21 won per 100 yen. That is close to the record low of 833.40 set in January 2008.
In plain terms, Korea has become noticeably more expensive for Japanese tourists. On the other hand, it has rarely been cheaper for Koreans to visit Japan. If you live in Korea and have been thinking about a trip to Tokyo or Osaka, the timing has seldom been better.
What the Korean Won Exchange Rate Means for Expats
Foreign residents feel these swings more directly than almost anyone. Whether the move helped or hurt you depends on one simple question. Which currency do you earn in, and which do you spend in?
If You Earn in Won
What a 4 million won monthly salary was worth in US dollars
For teachers, engineers and office workers paid in won, the summer was good news. A monthly salary of 4 million won was worth about $2,571 at the July peak. At the October 14 close, it was worth about $2,989. That is about $418 more every month, without any change in pay.
The gain matters most if you send money home, repay a loan in another currency or save for a move abroad. Of course, the benefit only lasts while the won stays strong. If you plan to convert a large sum, many expats split it into several smaller transfers. That way, a sudden swing in either direction does less damage.
If You Earn in Dollars
For remote workers, freelancers and digital nomads, the story is reversed. Imagine you rent a small studio in Seoul for 1.2 million won a month. At the July rate, that cost about $771. At the October rate, it cost about $897. Your rent did not change in won. It simply got about 16% more expensive in dollars.
That matters if you are weighing a move under the Korea digital nomad visa. It also matters for anyone comparing Seoul monthly rent with other Asian cities. For long-term stays, a strong won can quietly erase much of Korea’s price advantage.
Large Deposits and Jeonse
Housing deposits make the stakes even higher. Many foreigners pay key money of tens of millions of won when they sign a lease. Some even choose jeonse, Korea’s large lump-sum rental deposit. If you brought that money from abroad when the won was weak, you got more won for your dollars. When the deposit is returned and sent home, a stronger won will also give you more dollars back. The timing of both conversions can make a difference worth thousands of dollars.
Sending Money Home: The Rules
Korea still has strict rules on cross-border transfers, and they apply regardless of the rate. According to the Korea Herald’s guide to overseas transfers, foreign residents must register a designated foreign exchange bank. They can send up to $50,000 a year abroad without proving where the money came from. Above that, they must report the transfer with supporting documents.
Smaller thresholds apply as well. A single transfer above $5,000 requires documents showing the source of funds and the reason for the transfer. Transfers above $10,000 are reported to the National Tax Service and the Korea Customs Service. Therefore, keep your employment contract and tax records handy before you move large sums.
What the KRW to USD Swing Means for Tourists
For visitors, the weak won of the past two years was a gift. The Korea Culture and Tourism Institute noted that between January 2024 and May 2026, the US dollar gained about 12.6% against the won. The euro gained about 20.5%, and the Taiwanese dollar about 11.5%. That made shopping, food and hotels in Korea feel cheap for many travelers.
Visitors responded. In the first four months of 2026, Korea welcomed 6.77 million foreign tourists, up 21.4% from a year earlier. The institute now expects about 22 million visitors this year, well above the pre-pandemic peak. We covered the wider boom in our report on Korea inbound tourism.
The summer rally in the Korean won exchange rate has taken back part of that discount. A trip priced in won now costs American visitors roughly 16% more than it would have in early July. Still, the won remains weaker than it was for much of the last decade. For most tourists, Korea is still good value. It is simply not the bargain it was in June.
Three Money Tips for Visitors
- Always pay in won. Card terminals and ATMs sometimes offer to charge you in your home currency. Decline. That option, called dynamic currency conversion, usually comes with a worse rate.
- Use local money changers for cash. Licensed exchange counters in areas such as Myeongdong often beat airport rates. Compare a few before you change a large amount.
- Claim your tax refund. Many shops offer instant tax refunds on eligible purchases for foreign visitors. Bring your passport, because a refund can offset part of a stronger won.
For Investors: KRW to USD Is Part of the Return
For foreign investors, the Korean won exchange rate is not a side issue. It is part of the return. A foreign fund that bought Korean shares in early July earned the stock gain and the currency gain together. One that sold in the spring, by contrast, converted its won at some of the worst rates in 17 years.
There is also a valuation question. In late 2025, the IMF estimated the won’s fair value at about 1,330 per dollar, according to the Korea Herald. After the summer rally, the market has nearly reached that level. In other words, the easy part of the recovery may be over.
Policy differences matter, too. The US Federal Reserve raised rates on September 16 to a range of 3.75% to 4.00%, its first hike since July 2023. As long as US rates stay higher than Korean ones, the dollar keeps an advantage. The Bank of Korea meets again on October 22, and most economists expect one more hike before the end of the year.
Korean Won Outlook: Where Does It Go Next?
Forecasters are split, and the gap between them is wide.
The case for a weaker won. IBK Investment & Securities expects the rate to climb back to around 1,400 by the end of the year. It points to the widening interest-rate gap with the United States and a stronger dollar. It also expects more dollar demand as Korean companies build factories in America. If global conditions get worse, it sees a risk of the mid-to-high 1,400s by next year. Other analysts warn that pressure could stay high until the US midterm elections in early November.
The case for a stronger won. Others focus on Korea’s huge trade surplus. KB Securities, for example, expects the won-dollar exchange rate to drift gradually toward the 1,200 to 1,300 range over the medium term. Its argument rests on record trade and current account surpluses, a strong chip cycle and growth of 3% or more.
The structural wildcards. Several long-term forces could tip the balance either way. Korean households will keep investing abroad, which creates steady dollar demand. On the other hand, more global investors may buy Korean bonds and stocks as markets open further. New experiments, such as the won-backed stablecoin race, could eventually change how the currency moves across borders.
Three Dates to Watch
First, the Bank of Korea’s rate decision on October 22 will show whether it keeps tightening. Second, the US midterm elections in early November could move the dollar, which some analysts expect to stay firm until then. Third, Korea publishes its export data on the first day of each month. If the chip boom keeps the trade surplus near $30 billion a month, the dollar supply that powered the summer rally should continue.
For individuals, the lesson is less about prediction and more about planning. Few professionals called the July top. Even fewer predicted how fast the won would recover. If you need to move money across currencies, it may help to spread conversions over time and keep a buffer for sudden swings. This article is not financial advice, so consult a licensed adviser before making major currency decisions.
A Currency That Moves Your Life
Ten weeks in 2026 showed how much a single number can matter. The Korean won exchange rate moved salaries, rents, tourist budgets and investment returns, all without anyone changing a price tag.
For foreigners in Korea, the practical takeaway is simple. Know which currency you earn in and which one you spend in. Understand the transfer rules before you need them. Above all, do not assume that today’s rate will last. Recent history suggests the next big move may come just as quickly as the last one.
