A South Korean chipmaker will get paid in dollars for a shipment that closes three years from now. Nobody — not the CFO, not the bank, not the analysts — knows what the won-dollar rate will look like by then. This is exactly the kind of uncertainty a forward currency contract exists to solve.
Instead of waiting and hoping, the company calls its bank and locks in a rate today for a settlement years away. That agreement — pay a fixed number of won for one dollar in 2029, regardless of what the market does between now and then — is a forward currency contract. In Korean markets, this is what’s meant by “선물환 매도,” a company selling its future dollars forward. The exchange rate stops being a variable and becomes a number the company can build a budget around.
The bank isn’t doing this out of generosity. It takes the other side of the trade, then looks for a client who needs the opposite position — an importer who will owe dollars in 2029, for instance — and matches the two. The spread between what it charges each side is where the bank’s profit sits. If it can’t find a perfect match, it hedges the leftover risk elsewhere in the market. Either way, the risk doesn’t disappear. It moves to whoever is willing to hold it, for a price.
This matters more than usual right now. As of July 2026, South Korea opened won-dollar trading to a full 24 hours a day for the first time, replacing a market that used to close at 2 a.m. local time. Exporters like SK Hynix and Samsung, whose deals often close during U.S. afternoon hours, can now lock in a rate the moment a contract is signed instead of waiting for Seoul’s market to reopen. More hours to trade doesn’t remove currency risk — it just gives companies more chances to hand that risk to someone else, at a price both sides agree on.
That’s the part easy to miss in any hedging conversation: certainty isn’t free, and it isn’t created out of nothing. It’s transferred. Someone takes on the risk you just gave up, and prices it accordingly. If a deal looks like it protected everyone, that usually means you haven’t found where the risk actually landed.
When everyone seems to win, check who’s paying for it.
Not advice. Just how I see it.
