South Korean Won Strengthens: Hawkish BoK & KOSPI Correction Impact | BBH Analysis (2026)

The South Korean Won: A Currency on the Rise

The Korean Won (KRW) is having a moment in the sun, and it's all thanks to a combination of factors that are making it a currency to watch. In my opinion, the recent hawkish move by the Bank of Korea (BoK) has been a game-changer, and it's not just about the interest rate hike. Let's dive into why this matters and what it implies for the future of the KRW.

A Hawkish Move with a Twist

The BoK's decision to raise the policy rate by 25 basis points to 2.75% is a clear signal of its commitment to tackling inflation. But what makes this move particularly fascinating is the context. South Korea's real GDP growth of 3.8% year-over-year in Q1 and core inflation of 2.5% in June are already exceeding the BoK's 2026 projections. This means that the BoK is not just reacting to current conditions but is also looking ahead, which is a smart move in my view.

The KOSPI Correction: A Double-Edged Sword

The KOSPI index's sharp correction of 7.6% is a double-edged sword for the KRW. On one hand, it reduces the need for global investors to trim their Korean equity exposure, which removes a key source of KRW selling pressure. But on the other hand, it also means that the KRW's undervaluation is now more attractive, as the currency's value is supported by both policy tightening and valuation.

The Undervalued Currency: An Opportunity

The KRW is significantly undervalued, with an 11% deviation from its real effective exchange rate trend. This undervaluation is a key factor in the currency's strength, and it's not just a coincidence that the BoK has started to tighten policy at the same time. The South Korean government's efforts to internationalize the won are also a significant factor in the currency's appeal.

The Broader Implications

The KRW's strength has broader implications for the region. It suggests that the South Korean economy is on a solid footing, with strong growth and inflationary pressures. This, in turn, could lead to further policy tightening in the region, which could have a knock-on effect on other currencies. But it also raises a deeper question: is the KRW's strength sustainable in the long term?

The Future of the KRW

The future of the KRW is uncertain, but one thing is clear: it's a currency to watch. The BoK's hawkish move, the KOSPI correction, and the currency's undervaluation are all factors that could contribute to its strength in the short term. But in the long term, the KRW's future will depend on a range of factors, including the South Korean government's efforts to internationalize the won and the broader economic conditions in the region.

In my opinion, the KRW's strength is a sign of the South Korean economy's resilience and its ability to adapt to changing conditions. But it's also a reminder that the currency markets are complex and dynamic, and that there are no easy answers when it comes to predicting the future. So, let's keep an eye on the KRW and see where it takes us.
