South Korea’s benchmark KOSPI index tumbled more than 5% in early trading on Friday,
triggering a wave of panic across Asian markets, after rumours began swirling overnight
that the world’s largest cryptocurrency exchange, Binance, had suffered a multi-billiondollar hack. Within hours, bitcoin, ether and major altcoins were in freefall as traders
scrambled to pull funds from exchanges across the region.
The sell-off, which began in the pre-dawn Seoul session, extended beyond crypto.
Semiconductor giants Samsung Electronics and SK Hynix led a broader equities rout, with
investors unwinding risk positions amid worries that the suspected breach could cascade
into traditional financial markets. The Korean won slipped against the dollar, while Japan’s
Nikkei opened sharply lower in sympathy.
Binance has not yet issued a formal statement confirming or denying a hack, though social
media posts from users unable to withdraw funds have been multiplying since the early
hours of Friday. On-chain analysts pointed to several unusual wallet movements overnight,
with billions of dollars in stablecoins reportedly shifting between addresses in rapid
succession.
The timing could not be worse for a crypto market already battered by this year’s volatility.
Bitcoin, which had traded above $120,000 earlier in the week, briefly plunged below
$100,000 in the hours after the rumours surfaced before clawing back some losses. Ether
and solana saw double-digit percentage drops.
South Korea has one of the world’s most active retail crypto markets, with household names
regularly trading tokens alongside stocks. That retail concentration helps explain why the
KOSPI absorbed such a sharp blow: when crypto wobbles, Korean portfolios tend to feel it
fast.
Regulators in Seoul reportedly held emergency conversations through the night. The
Financial Services Commission is understood to be in contact with major domestic
exchanges, including Upbit and Bithumb, to assess exposure. European regulators and the
U.S. Securities and Exchange Commission have yet to comment publicly, though sources
suggest they are monitoring the situation closely.
This latest shock lands against a backdrop of jittery global markets. Investors are already
contending with the fallout from a renewed Iran conflict, Spain’s deadly high-speed rail
crash earlier this week, and worries that AI-sector spending has outpaced returns. A
confirmed Binance breach, if it materialises, would be the largest exchange hack in crypto
history, dwarfing the 2022 FTX collapse.
For now, the picture is a swirl of rumour, panic withdrawals, and plunging prices. Binance’s
silence has only amplified the anxiety. Whether this becomes the defining crypto event of
2026 or a false alarm driven by social-media contagion should become clearer in the next
24 hours. Until then, markets are flying blind.
Investors are advised to treat unverified reports with caution and watch official statements
from Binance and regional regulators before acting.
