The South Korean won remains weak against the U.S. dollar despite a recent memorandum of understanding to end the war between the U.S. and Iran [1].

This persistence of high exchange rates is concerning for South Korea because it threatens to drive up the cost of imports and fuel domestic inflation. While a peace agreement typically stabilizes markets, the currency is not responding as expected.

In the New York market early Saturday, the won-dollar exchange rate closed at 1,531 won [1]. This figure represents an increase of nearly four won compared to the closing price of the Seoul market [1].

Several complex factors are contributing to this volatility. Market analysts point to uncertainty regarding U.S. monetary policy and delays in follow-up negotiations between the U.S. and Iran [1]. Additionally, disruptions in oil supplies and profit-taking by foreign investors in the KOSPI market have played a role, alongside speculative trading [1].

The Bank of Korea is monitoring the situation closely as it projects inflation trends for the remainder of the year. The central bank forecasts an average inflation rate of 3% for the second half of the year [1]. The projected core inflation rate stands at 2.6% [1].

Kim Young-joo, head of the Bank of Korea's Price and Employment Department, said that the impact of currency fluctuations on consumer prices is not immediate. Kim said that prices for industrial products and services typically show the strongest reaction after a time lag of approximately 14 to 18 months [1].

Despite the diplomatic breakthrough between Washington and Tehran, the financial markets in Seoul are still grappling with the ripple effects of the conflict and the unpredictability of global trade [1].

The won-dollar exchange rate closed at 1,531 won.

The disconnect between a diplomatic peace agreement and currency stability suggests that the market is prioritizing monetary policy and supply chain risks over geopolitical relief. For South Korea, the delayed transmission of exchange rate hikes into consumer prices means the full economic impact of the current won depreciation may not be felt for over a year, potentially creating a long-term inflationary tail.
