South Korea has announced a significant expansion of its foreign-currency bond issuance program, more than tripling the planned ceiling to $5 billion as part of its 2026 budget plan. This marks a substantial increase from the previously planned cap of $1.4 billion.
The government's primary objectives are to stabilize the South Korean won (KRW) and attract foreign investment. This policy shift comes in response to increased pressure on the currency market, driven by a surge in U.S. dollar demand following a recent major trade deal with the United States. The won has faced sustained depreciation pressure due to robust dollar demand, high oil prices, and global trade concerns.
Proceeds from the overseas bond sales will be used to manage foreign exchange pressures and support the implementation of a $350 billion U.S. investment deal. The bond program is also aligned with South Korea's broader 20-year, $200 billion investment plan with the United States.
To appeal to a wide range of investors, South Korea is offering Korea Treasury Bonds (KTBs) with maturities ranging from 2 to 50 years. This strategy allows the government to spread its debt obligations over time and caters to both long-term investors like pension funds and shorter-term participants such as banks.
The country's strong credit ratings are a key selling point. Fitch rates South Korea's long-term debt at "AA-", while S&P assigns ratings of "AA" for long-term and "A-1+" for short-term debt. These ratings are expected to help attract an estimated $15 billion to $20 billion in foreign investment. The bonds offer attractive yields; for instance, the five-year dollar bonds issued in October 2025 paid a slightly higher rate than comparable U.S. Treasury bonds.
The Ministry of Economy and Finance is coordinating with key domestic institutions, including the National Pension Service and major exporters like Samsung and SK Hynix, to balance foreign currency supply and demand and maintain won stability. The government has also imposed a strict $5 billion cap on the issuance to protect the currency from excessive volatility and has reached an agreement with the U.S. to avoid unfair currency manipulation.
