US OvernightThe Nasdaq fell 1.55% to 25,873.18, the S&P 500 dropped 0.79% to 7,515.34, and the Dow slipped 0.26% to 52,498.64. The session was hit by two forces simultaneously.

US Overnight
The Nasdaq fell 1.55% to 25,873.18, the S&P 500 dropped 0.79% to 7,515.34, and the Dow slipped 0.26% to 52,498.64. The session was hit by two forces simultaneously. First, the Korea-driven chip rout continued: SK Hynix's US-listed ADRs plunged 9.3% on their second trading day, falling to within a few dollars of their $149 IPO price, after Seoul shares crashed 15.37% — the worst day in the company's history — on a brokerage report questioning quarterly profit estimates. The KOSPI fell 5.5%, triggering circuit breakers for the 35th time this year. Second, Trump posted on Truth Social that he was reinstating "THE IRANIAN BLOCKADE" and that the US would serve as "GUARDIAN OF THE HORMUZ STRAIT," collecting a 20% toll on all cargo shipped through the waterway. Oil surged roughly 9%: WTI jumped to $78.09 and Brent to $83.15 — the sharpest single-day move since the war began. The chip index fell 4.78% while the software ETF gained 0.37%, extending the hardware-to-software divergence.
Key Movers
SK Hynix ADR (SKHY) -9% — SK Hynix's Nasdaq ADRs fell 9.3%, erasing nearly all of Friday's 13% IPO debut gains. The $26.5 billion IPO — the largest by a foreign company in US history — is now underwater relative to last week's euphoria. Bloomberg noted the decline "underscores growing investor concerns that the boom is overextended." A brokerage report questioning SK Hynix's quarterly estimates triggered the Seoul crash that spilled into the US session.
Memory / Chips: SanDisk -12%, ARM -8%, AMD -4% — SanDisk plunged over 12%, extending its correction to roughly 35% from recent highs. ARM dropped nearly 8%, AMD fell 4.21%, and Nvidia declined 3.52%. Micron sank as much as 7% intraday. The SOX has swung violently in both directions over the past two weeks, erasing a significant chunk of Q2's 88% rally.
Oil +9%: WTI $78, Brent $83 — Trump's blockade reinstatement sent crude surging to levels not seen since early July. The 20% toll announcement adds a new structural cost to Hormuz shipping. Energy stocks rallied while the rest of the market fell. The timing — one day before CPI — could not be worse for inflation expectations.
SGX Preview
The STI was near 5,070. DBS near S$62.18, UOB near S$37.91. Oil spiking 9% to $83 is a significant headwind for Singapore's import-dependent economy, reversing weeks of declining energy costs. The chip selloff pressures Venture Corp. Tonight's CPI and bank earnings will dominate sentiment: a cool CPI reading despite the oil move would be very bullish, while a hot print plus Trump's new blockade could trigger a broader risk-off.
Asia Pre-Market
Brent at $83 and WTI at $78 mark the sharpest reversal since the June MOU signing. The 20% Hormuz toll is a new variable that no model has priced in. Gold fell to ~$4,016 and the 10-year yield rose to 4.60%. The market enters CPI day with oil 15% above where it was a week ago — a dramatic shift that complicates the disinflation narrative.

Data Spotlight: June CPI — May CPI was 4.2% with oil averaging ~$95. June oil averaged ~$72 before this week's spike. If the data captures the mid-June peace discount, headline CPI could drop below 4% — a milestone. But Trump's blockade reinstatement means any relief is temporary: July CPI will re-accelerate if Brent stays above $80. The five bank earnings will reveal whether rate hike fears are translating into credit tightening or whether loan demand remains healthy despite the 4.5%+ yield environment.
One More Thing
Trump reinstating the blockade the day before CPI is either terrible timing or deliberate. If June CPI drops below 4% on the old oil data, markets rally — but the rally is immediately capped by $83 Brent and a 20% Hormuz toll that will push July inflation right back up. The market is trapped between backward-looking data (good) and forward-looking policy (bad). Tonight's CPI number is already stale. The real inflation story is being written on Truth Social.
