The South Korean won fell to 1,511 won per dollar on Monday, its weakest level since March 2009, as the war in Iran sent investors rushing into safe-haven assets.
The dollar’s surge is real — but in Korea’s crypto markets, the kimchi premium on tether has quietly collapsed.
Won Freefall Drives Dollar Demand
Seoul’s foreign exchange market opened at 1,504.9 won before spiking to 1,511.8 won intraday. The dollar index climbed from the mid-97 range to nearly 100 since the Iran conflict began on March 1.
Iran’s blockade of the Strait of Hormuz is pushing oil prices higher, adding another layer of inflationary pressure on the won. Foreign investors sold a net 335.7 billion won worth of KOSPI shares in early trading, triggering the sixth circuit breaker of the year.
Historically, Korean retail investors have treated USDT as a convenient dollar surrogate, bidding it above parity during periods of won weakness and crypto volatility. The kimchi premium — which spiked as high as 7.47% on Bithumb during October’s market panic — served as a reliable gauge of retail euphoria, with traders buying USDT to rotate into bitcoin and altcoins during volatile periods.
Why USDT Isn’t Following the Script
On Upbit, South Korea’s largest exchange, USDT trades around 1,503 KRW — roughly 0.5% below the spot dollar rate. Normally, Korean retail investors pay a premium for tether during dollar rallies, treating it as a dollar proxy.
This time, the dynamic has reversed. Rising geopolitical risk has dampened speculative appetite for crypto, reducing demand for USDT as a trading vehicle. Investors are moving into actual dollars and dollar-denominated assets rather than stablecoin positions.
The result is a rare “USDT discount” — the stablecoin tracking below its peg in Korean won terms — signaling that crypto markets are not participating in the safe-haven trade driving traditional FX.
Trump’s 48-hour ultimatum to Iran over the Hormuz Strait, and Tehran’s threat of permanent closure in response, suggests the pressure on the won is far from over.
