Trump's Hormuz Blockade Reignites Oil Shock as Chip Stocks Lead Wall Street Lower

Oil Spikes, Chips Slide as Trump Reimposes Iran Blockade to Open the Week

Trump Reimposes Iran Blockade, Adds 20% Toll on Hormuz Shipping

• President Trump said on Truth Social that the U.S. is reinstating its blockade on Iran and will charge a 20% "toll" on all cargo shipped through the Strait of Hormuz, framing the move as reimbursement for the region's defense costs.
• WTI crude jumped roughly ▲ 9% to around $77–78 a barrel, and Brent gained a similar amount to near $83 — oil's largest one-day move since early April — as traders priced in the risk of disrupted shipping through the world's most important oil chokepoint. Analysts described the move as a genuine repricing of geopolitical risk rather than a short-lived trading pattern, given how directly it ties into Tuesday's CPI report and the incoming Fed chair's first testimony before Congress.
• Treasury yields rose as bond investors weighed oil-driven inflation risk: the 2-year yield climbed to roughly 4.27% and the 10-year added nearly 3 basis points to 4.598%.
• The announcement landed just three trading days after SK Hynix (SKHY) raised $26.5 billion in the largest-ever U.S. listing by a foreign company — turning Monday's session into a pivot from IPO euphoria back to geopolitical risk.

Memory Chips Give Back Friday's Gains as SK Hynix Slides 15%

• SK Hynix (SKHY) tumbled ▼ 15.4% in its first day of full Nasdaq trading — just three sessions after its record-setting debut — after a brokerage report questioned whether the company can meet its own quarterly profit estimates.
• The selloff started overnight in Seoul, where the KOSPI fell 9.0% and is now down 20.5% from its June 22 peak, dragging Samsung Electronics down roughly 10.7%.
• Micron Technology (MU) fell ▼ 5.76% and SanDisk (SNDK) dropped ▼ 9.62% as the memory-chip trade unwound on signs that production yields are improving faster than expected, easing the supply shortage that had been driving premium pricing.
• Weakness spread across the broader chip tape: Nvidia (NVDA) slipped alongside peers as the Technology Equipment sector fell roughly 2.1% and the semiconductor-focused SOXX ETF dropped about 4.8%.

Energy Majors Were the Rare Bright Spot

• Exxon Mobil (XOM) climbed ▲ 3.10%, outperforming Chevron (CVX) ▲ 1.96% and Occidental Petroleum (OXY) ▲ 1.61%, as the day's oil spike lifted energy majors' profit margins; the sector was the best-performing group on the day, up roughly 2.2%.
• Biogen (BIIB) advanced after Jefferies, RBC Capital, and Bank of America raised price targets ahead of Phase 2 Alzheimer's data due at the AAIC conference in London later this month.
• Fastenal (FAST) rose about ▲ 1.2%, one of the steadier industrial names on an otherwise red day.
• Apple (AAPL) inched up ▲ 0.6%, one of the only mega-cap tech stocks to hold gains as chipmakers absorbed the brunt of the selloff.

Gold Breaks From the Safe-Haven Script Ahead of CPI and Fed Testimony

• Gold fell about ▼ 1.8% to roughly $4,000–$4,045 an ounce, and silver dropped ▼ 3.6% to under $58 — an unusual break from typical safe-haven behavior, as traders positioned for Tuesday's inflation data instead of reaching for havens.
• Treasury yields rose across the curve: the 2-year near 4.27% and the 10-year near 4.60%, both reflecting inflation risk tied to the oil spike.
• Market breadth stayed negative into the close, with decliners outnumbering advancers on the Nasdaq roughly 3,060 to 1,620 — about 65% of the tape lower on the day.
• Incoming Fed Chair Kevin Warsh testifies before the House Financial Services Committee Tuesday and the Senate Banking Committee Wednesday — his first major public remarks on rate policy will be parsed closely alongside the CPI print.

What to Watch Tuesday, July 14 and Beyond

• June CPI (Tuesday, July 14, 7:30 AM CT). The first major inflation read since oil's Iran-driven spike — markets are watching for any pass-through into energy and core prices.
• Fed Chair Kevin Warsh testifies before Congress Tuesday before the House Financial Services Committee and Wednesday before the Senate Banking Committee — his tone on rate policy could move yields and equities through the back half of the week.
• Q2 bank earnings open Tuesday before the bell with JPMorgan Chase and Goldman Sachs, followed by June PPI data on Wednesday.
• SK Hynix's first full week of regular trading continues — expect more volatility as the market digests Friday's record IPO pricing against Monday's 15% slide.
• The Strait of Hormuz situation remains the biggest wildcard for oil and risk sentiment; further escalation or a walk-back of the blockade could swing markets sharply this week.
