Korean Stocks Hit Circuit Breaker as SK Hynix Drops 7%; Leveraged ETFs Amplify Sell-Off
Claire Weston
Meta's plan to sell spare compute capacity shattered the 'absolute chip scarcity' narrative, triggering a global semiconductor rout: KOSPI 200 futures plunged 5% and hit a circuit breaker, SK Hynix tumbled 7.6% at the open, and leveraged ETFs are mechanically amplifying the damage far beyond fundamentals.
Who fired the first shot in this sell-off?
The catalyst was Meta's strategic pivot: Bloomberg reported that Meta is building a new business to sell excess compute capacity to outside clients.
This means → the market's core belief in "absolute compute scarcity" took a direct hit. If compute can be rented like a commodity, hardware makers lose pricing power.
Meta's stock surged 10% on the day — its best performance this year. On the flip side, Nvidia, Micron and other AI hardware names were hammered; the U.S. semiconductor index fell 6.3% in a single session.
Why did Korea take the worst beating?
KOSPI opened down 4.5% on July 2, then widened to over 6%, breaking through 7,800. KOSPI 200 futures fell 5% and triggered a circuit breaker, halting programmatic trading for five minutes.
SK Hynix dropped 7.6% at the open; Samsung Electronics fell 6.5%. SK Hynix carries a 28% weighting in KOSPI — its share price has become a barometer for global AI sentiment.
In plain terms = one stock accounts for nearly a third of the index. When it drops, the entire benchmark gets dragged down with it.
How are leveraged ETFs making the drop worse?
The $13 billion CSOP SK Hynix leveraged ETF can account for two-thirds of SK Hynix's total trading volume on volatile days.
Nomura estimates that for every 1% move, leveraged ETFs generate roughly $9 billion in rebalancing demand. This means → a 1% decline forces the ETFs to mechanically sell $9 billion in positions, which pushes the stock lower, which forces more selling — a self-reinforcing loop.
In plain terms = leveraged ETFs act like a magnifying glass — they amplify gains on the way up and losses on the way down, and the process is fully automatic, with no human in the loop.
Korean regulators have expressed regret over 16 copycat leveraged ETFs tracking chipmakers approved in May, noting that over 90% of their investors are retail traders.
How hard were other Asian markets hit?
The sell-off spread beyond Korea: the Nikkei 225 widened its decline to 2% intraday, and the MSCI Asia-Pacific index fell 1% overall.
S&P 500 futures slipped a further 0.2% during the Asian session, signaling that overnight U.S. selling pressure had not fully dissipated.
Is there any good news on the macro front?
Fed Chair Kevin Warsh told the ECB's annual forum in Sintra that inflation expectations have eased over the past month and price risks have declined in recent weeks.
Evercore analyst Krishna Guha read this as "the new Fed chair sees no reason to raise rates immediately," and expectations for a July hike cooled accordingly.
Oil fell in tandem: Brent dropped 0.8% to $71 a barrel; WTI fell 1.1% to $67.80, the lowest since late February, driven mainly by progress in Middle East peace talks. Gold edged up 0.3%, holding above $4,000.
What is the market watching next?
Two key checkpoints lie ahead: ① whether Meta's compute-selling plan materially changes the pace of data-center buildout; ② whether the mechanical rebalancing pressure from leveraged ETFs eases once liquidity improves.
SK Hynix is planning a $29 billion U.S. listing. This reflects the company's search for additional liquidity — if the listing succeeds, trading spread across two markets could dilute the squeeze effect of leveraged ETFs in any single venue.
Goldman Sachs warned: once compute supply rises and rental prices fall, the scarcity narrative will be upended outright — and hardware will feel the pain first.
