South Korea's Finance Minister Koo Yun-cheol on Friday, 19 June said the memorandum of understanding (MOU) signed between Washington and Tehran to end their conflict opens both fresh economic opportunities and significant challenges for Seoul. Speaking at a ministerial meeting on international economic affairs, Koo confirmed the government would move swiftly to implement post-conflict economic policies.

Seoul's Strategic Response to the US-Iran MOU

Minister Koo outlined a dual-track approach: securing long-term cooperation with Middle Eastern nations on reconstruction and fiscal recovery, while simultaneously reinforcing South Korea's economic security and supply chain resilience. 'We will aim to secure areas of cooperation with Middle Eastern nations on reconstruction and improving their fiscal health,' Koo said. 'We will address risks in the global supply chain highlighted by the recent conflict.'

This comes amid a broader recalibration of South Korean foreign economic policy, as Seoul attempts to position itself as a key partner in any post-conflict rebuilding effort in the region.

US Tariff Pressure Adds to Seoul's Burden

Separately, Minister Koo addressed proposed US tariffs targeting 60 trading partners — including South Korea, Asia's fourth-largest economy — over alleged failures to enforce import bans on goods produced with forced labour. The Office of the US Trade Representative (USTR) has proposed levies of 10% or 12.5% on products from the affected nations.

Koo said Seoul would take a proactive stance in bilateral trade negotiations. 'By thoroughly addressing overall trade-related agendas with the US, we will make efforts to ensure South Korean companies are not placed at a disadvantage,' he said. The minister signalled a preference for a balanced resolution that serves both countries' interests, rather than a confrontational posture.

Strait of Hormuz and Shipping Security

At a separate economy-related meeting, Koo acknowledged that while external uncertainties appear to be easing following the US-Iran MOU, the economic fallout from the conflict continues to weigh on South Korea. The government pledged to closely monitor developments in the Middle East and to support the safe and timely passage of South Korean vessels through the Strait of Hormuz — a critical chokepoint for global energy and trade flows.

Impact on Jobs, Prices and Financial Markets

Koo highlighted that the conflict's economic ripple effects — including slowing employment, consumer price hikes, and volatility in foreign exchange markets and key interest rates — continue to linger. 'The government will spare no effort to ease the burden on people's livelihoods,' he said. Notably, South Korea is among the economies most exposed to Middle East energy disruptions given its heavy reliance on Gulf crude imports.

What Comes Next

Seoul is expected to engage actively with both US trade officials and Middle Eastern partners in the coming weeks as the post-conflict economic landscape takes shape. The government's ability to convert the MOU into tangible reconstruction contracts — while managing US tariff pressure — will be the key test of its economic diplomacy in the second half of 2025.
