South Korea and the United States are in a decisive phase of negotiations over a $350 billion investment fund. The investment fund aims to lower US tariffs on Korean exports and strengthen economic ties.
Finance Minister and Deputy Prime Minister Koo Yun-cheol, joined by Presidential Policy Chief Kim Yong-beom and Industry Minister Kim Jeong-kwan, visited the White House Office of Management and Budget on Thursday. They sought to finalize the legal and administrative language for the investment fund.
Negotiations have lasted months, focusing on the fund’s structure and safeguards against currency volatility. Both sides agreed on a framework in July, but disagreements over technical details delayed the final deal.
President Trump demanded upfront cash investments. South Korea proposed a hybrid model with loans, guarantees, and a foreign-exchange safety mechanism to stabilize the won. Options include an unlimited swap line with the Federal Reserve or phased funding via Korea’s Foreign Exchange Stabilization Fund.
Treasury Secretary Scott Bessent said Wednesday that officials expect a breakthrough “within 10 days.” Korean leaders noted that Washington now understands Korea’s financial market better.
The investment fund negotiations carry broader economic implications. Analysts say the currency mechanism would prevent market disruption and boost investor confidence. They also stress that resolving technical issues strengthens regional economic stability.
Officials plan to use the Asia-Pacific Economic Cooperation summit, starting October 27 in Gyeongju, to formalize the investment fund agreement. Leaders aim to signal commitment to trade and financial cooperation during the summit.
In conclusion, the investment fund talks mark a key moment in South Korea–US relations. Finalizing funding and currency safeguards will support trade, stabilize the won, and reinforce bilateral economic ties.
