Korean Corporations Dump Dollars at Record Pace — The Won Crisis Is About to Hit Exporters

The export windfall is turning into a chokehold.

Korean companies sold dollars at a staggering pace in the second quarter — nearly 3.7 times the volume they moved a year earlier — flooding the foreign-exchange market with proceeds that were supposed to strengthen the won and relieve pressure on import costs. Instead, they’ve set off a chain reaction that threatens the very exporters the government was trying to shore up.

According to data obtained by lawmaker Kim Nam-jun from the Bank of Korea, non-financial private corporations sold $263.59 billion in spot and forward dollars in Q2, up 71.5% from $153.67 billion a year prior. But their dollar purchases — money they’d need for imported inputs, overseas investment, and debt repayment — grew a far more modest 23.9%, from $124.2 billion to $153.94 billion. The gap between selling and buying exploded. Net dollar selling hit $10.965 billion, compared with $2.947 billion in the same quarter last year.

For the first half of the year, the picture was even starker: $186.9 billion in net dollar selling, roughly triple the $58.49 billion recorded in H1 2024. The market has been drowning in dollars.

The sheer scale of this outflow is difficult to overstate. To put it in context, the combined value of Korea’s merchandise exports in June alone comes to roughly $50 billion. These corporations didn’t just sell dollars — they dumped them in a torrent that no single week of export earnings can explain. Something structural shifted.

How we got here.

The dollar-won spike to the 1,500 level earlier this year forced the government’s hand. In June, officials convened meetings with major exporters and explicitly urged them to convert export receipts quickly and repatriate funds held overseas. The message was clear: a weaker won was raising consumer prices and squeezing household budgets, and the state wanted the dollar tide reversed.

The request worked. Shipbuilders accelerated forward-dollar sales. SK Hynix brought in proceeds from American Depositary Receipts issued in the United States. Exporters who had been holding dollars offshore to hedge future receivables decided now was the time to bring them home.

But there’s a subtler force at play that goes beyond government messaging. Companies that had accumulated dollar holdings during the 2022–2023 currency crisis were sitting on unrealized gains as the dollar weakened through the spring. Locking in those positions became not just a patriotic act but a financially rational one — especially when the cost of hedging against further dollar strength rose sharply alongside broader volatility in global markets.

The market responded within weeks. The dollar-won rate dropped below 1,500 in mid-July for the first time in over a month, then sliced through 1,400 on August 19. On that day, it touched 1,376.50 won — the lowest level since September 17, 2024, when it briefly dipped to 1,375.70 won.

Kim Nam-jun praised the outcome, arguing that the stability reflected a virtuous cycle: strong AI and semiconductor exports brought dollars in, which stabilized the currency, which in turn should feed back into domestic investment.

That logic sounds clean on paper. It doesn’t account for what happens when the dollar keeps falling.

The second-order effects no one is talking about.

Here’s where the story gets compounding. A stronger won doesn’t just make exports more expensive abroad — it quietly deteriorates the competitive position of Korean firms in ways that take months or years to materialize. When the won strengthens sustainably, multinationals like Samsung and Hyundai face a choice: absorb the margin compression or raise prices. Raising prices cedes market share to Japanese and Chinese competitors who aren’t fighting the same currency headwind. Absorbing the compression erodes the very earnings that fund R&D and capacity expansion.

Smaller suppliers are hit even harder. They lack the hedging sophistication of the chaebols and often operate on razor-thin margins. A move from 1,500 to 1,376 represents roughly a 9% shift in the won’s purchasing power relative to the dollar. For a supplier pricing contracts in dollars with won-denominated costs, that’s not a rounding error — it’s a structural margin kill.

Then there’s the capital-flow dimension. A strengthening won attracts carry-trade flows from investors who borrow cheaply in yen or dollars to buy won-denominated assets. But these flows are fickle. They arrive quickly and vanish at the first sign of geopolitical risk or central-bank uncertainty. The BoK has watched this movie before — the 2022 capital outflow spiral didn’t materialize in a vacuum, and history suggests it could recur if expectations shift.

Finally, there’s the psychological feedback loop. Exporters who saw their dollar revenues worth significantly fewer won this quarter will revise their earnings forecasts downward. Revised forecasts depress stock prices. Depressed stock prices weaken corporate balance sheets. Weaker balance sheets reduce the ability to invest or service debt. The strong won that was meant to protect the economy begins to undermine it from the inside.

Who wins. Who loses.

Importers and consumers win, at least in the short term. A weaker dollar means cheaper energy, food, and raw materials — exactly what the Bank of Korea needed to see before considering rate cuts. It also reduces the pain of servicing dollar-denominated debt, which has been a quiet strain on corporate balance sheets.

But exporters lose. Every step the won takes toward 1,350 or lower erodes the price competitiveness of Samsung Electronics, Hyundai Motor, LG Energy Solution, and the thousands of suppliers in between. Korea’s export-dependent economy — where exports account for roughly 40% of GDP — cannot sustain a prolonged strong won without seeing margins compress and order books soften. That has already begun. Semiconductor exporters, the crown jewels of the trade surplus, are watching their won-equivalent revenues shrink even as nominal dollar earnings hold steady.

Shipbuilders, ironically, are among the groups the government encouraged to sell dollars forward. Now they face a dual pressure: a stronger won makes their contracts less competitive in global bidding, while their own hedging strategies have contributed to the very currency movement that undermines them.

The Bank of Korea’s trap.

This is where the story gets tighter. The BoK has faced persistent criticism for keeping rates too high for too long, even as growth slows. A strong won gives the central bank an exit ramp — lower inflation from cheaper imports creates room to cut without reigniting price pressures. But cutting rates into a strengthening won is a recipe for capital outflows and renewed currency volatility. And if the BoK intervenes to prop up the won by buying dollars, it reverses the government’s own policy and drains its FX reserves.

There is no clean move. Raise rates to defend the currency and risk deepening a growth slowdown. Cut rates to stimulate the economy and risk another currency spiral. Stay put and let the won drift, watching exporters bleed competitiveness.

The data suggests the BoK is already weighing its options. The net dollar selling figure — $186.9 billion in the first half alone — is large enough to move markets for months. Whatever the central bank does next, it will be responding to corporate behavior that it cannot easily reverse.

What comes next.

The trend is unlikely to pause. Q3 data is tracking along similar lines, and with semiconductor export revenues still running hot, there will be more dollars hitting the market. Unless the won strengthens enough to naturally dampen export earnings — or the government shifts its stance on currency intervention — the pressure on exporters will intensify through year-end.

The critical window is closing. If the won breaches 1,350 before the BoK signals a clear framework for managing the exchange rate, we could see a credibility crisis develop — not just for the central bank but for the broader institutional architecture that has managed Korea’s open economy for three decades. Exporters who once trusted the state to balance competing priorities will lose faith in that balancing act.

The Bank of Korea stands at a fault line. It can let the market run its course and watch the export sector erode gradually. It can intervene aggressively and risk triggering the very capital-flight dynamics it fears. Or it can signal a shift in posture — hinting that the dollar-selling campaign has achieved its purpose and that future policy will tolerate a weaker won — and let expectations adjust without a dramatic policy pivot.

None of those options are easy. All of them require acknowledging that the policy which solved one problem has simply migrated the risk elsewhere. The export windfall that was meant to be a blessing is now a double-edged sword, and the blade is swinging back.
