Episode Description:
A $50 billion Nvidia lease reignited circular-financing fears just as China's chip breakthrough sent the Kospi into its third circuit breaker of the month.
Kospi fell 10.84% to 6023.66 after news that a Chinese state-linked firm has begun producing its own DUV lithography equipment, while Nvidia's data center lease with Hut 8 deepened concerns over AI-sector circular financing. Samsung Electronics and SK Hynix posted their sharpest one-day losses of the year, and Nvidia's credit default swap premium spiked to levels not seen since last year. Foreign investors sold heavily while retail investors bought the dip, setting up a critical earnings week for Korean chipmakers and the Fed.

00:063 Numbers That Should Worry Anyone Holding Korean Assets Today
00:11Nvidia just locked in a $50 billion data center lease, and circular financing fears are back.
00:18Korea's Kospi crashed more than 10% today, triggering the market's third circuit breaker this month.
00:24A Chinese state-linked firm just started building its own lithography equipment,
00:30and Washington and Seoul just found a $200 billion reason to build LNG plants together in Texas.
00:37It's Wednesday, July 29th. Here's why global investors are paying attention to Korea today.
00:45Nvidia has agreed to lease Hut 8's entire 1-gigawatt Texas data center for up to $50 billion over 30
00:53years,
00:54deepening its role as both chip supplier and infrastructure backer.
00:58On the same day, reports emerged that a Chinese state-linked firm has begun producing
01:04immersion DUV lithography tools for domestic memory makers.
01:09Together, the two stories reignited fears that AI chip demand is inflated by circular financing,
01:16and that China's chip self-sufficiency is arriving faster than expected.
01:20Here's what the numbers show.
01:23The Kospi dropped 732.09 points, or 10.84%, to close at 6,023.66, its third circuit breaker this
01:36month.
01:37Samsung Electronics fell 13.39% to 220,000 won, $159, and SK Hynix dropped 14.65% to 1
01:51,555,000 won, $1,127,
01:56the sharpest one-day semiconductor sell-off of the year.
02:01Nvidia's five-year credit default swap premium jumped to around 0.82%,
02:07up from a 0.35% to 0.50% range since December, pricing in fresh circular financing risk.
02:17Foreign investors sold $4.97 trillion won, $3.6 billion, of Korean stocks,
02:26while retail investors bought $4.33 trillion won, $3.1 billion, the same day.
02:34Citadel Securities forecast a surprise Fed rate hike on July 30th,
02:39a move that would raise funding costs for CapEx-heavy tech firms.
02:43So what does this mean for global investors watching Korea?
02:48Earlier, we said Nvidia's $50 billion lease revived circular financing worries.
02:54Here's what that actually means for you.
02:57If AI infrastructure spending is being financed in a closed loop between chip makers and their own customers,
03:05real demand may be harder to verify than headline CapEx numbers suggest.
03:10For now, that argues for watching upcoming earnings from Samsung, SK Hynix, and big tech hyperscalers
03:18for hard evidence of order books, not pledged CapEx.
03:23Three things to watch.
03:26First, SK Hynix reports earnings on July 29th, followed by Samsung Electronics on July 30th.
03:33Second, the FOMC decision lands July 30th, with Citadel already flagging surprise hike risk.
03:42Third, Alphabet's CapEx guidance, already raised to $205 billion for the year,
03:50will set the bar for how markets judge the rest of big tech's AI spending this earnings season.
03:55That's today's AI Prism, Global Investors.
