South Korea’s won has had a rough stretch. The currency recently dropped to near 17-year lows against the dollar.
SK hynix, South Korea’s dominant memory chipmaker, completed what is now the largest American Depositary Receipt listing in US history on July 10, 2026. The company priced 177.9 million ADRs at $149 each, raising approximately $26.5B in a single transaction.
How a chip listing becomes an FX event
When SK hynix raises dollars through a US listing, those proceeds eventually need to find their way back to South Korea. That means converting dollars into won, which increases demand for the Korean currency and, all else equal, pushes its value higher.
The Bank of Korea estimates that total dollar inflows related to the listing could reach as high as $30B when factoring in associated capital movements.
Forward hedging is already happening. SK hynix and local banks began initiating forward sales as early as July 2026, a standard practice where sellers lock in an exchange rate today for a transaction that settles later. That activity alone is already showing up in spot rates.
The won appreciated 0.5% in direct response to news that dollar conversion preparations were underway.
Why the timing matters for South Korea
The won’s slide to near 17-year lows has been a persistent source of concern for Korean policymakers. A weaker currency raises import costs, contributes to inflationary pressure, and can spook foreign investors who do not want their returns eroded by exchange rate moves.
SK hynix sits at the center of South Korea’s export-driven semiconductor economy, particularly given its position in high-bandwidth memory chips, which have become essential infrastructure for AI model training and inference. The Nasdaq listing is partly a bet that Western investors want direct exposure to that AI hardware supply chain.
What investors should watch now
For FX traders specifically, the forward hedging activity is the key variable to track. As settlement dates approach and actual dollar-to-won conversions are executed, the spot rate impact will be felt in phases rather than all at once. The Bank of Korea’s $30B inflow estimate suggests there is more currency-positive flow still in the pipeline.
