2026.6.18 US Stock Daily | The Strait Reopened, Chips Went Ballistic

The Nasdaq closed up 1.91% at 26,517.93, the S&P 500 rose 1.08% to 7,500.58, and the Dow gained just 0.14%. All three indices moved in the same direction but with wildly different magnitudes — the gap was entirely semiconductors. The semiconductor ETF surged 5.76% in a single session, dragging the Nasdaq out of the hole left by yesterday’s Waller debut.

Two things collided. Trump announced a partnership between Intel and Apple, and Intel simultaneously announced it would spin off its foundry and advanced packaging business as an independent operation. The chips-made-in-America narrative now has a concrete corporate vehicle, and the market cast its vote in the most direct way possible: the Technology Select Sector ETF (XLK) rose 3.04%, and the semiconductor ETF jumped 5.76%.

The other development was bigger. The US-Iran deal landed, and the Strait of Hormuz reopened to traffic. WTI crude fell to $75.52, down 1.65% — Reuters headlined it as “pre-Iran-war lows.” The energy sector (XLE) dropped 1.65% tracking oil, but for the broader market this was a tailwind: shipping lanes cleared, energy cost expectations declined, and one inflation variable was taken off the table.

This also explains today’s most counterintuitive data point: oil down, dollar up. The US Dollar Index rose 0.69% to 100.78. As geopolitical supply-side risk premium faded, capital read it as diminished safe-haven demand flowing back into the dollar — not as a signal of global demand weakness. The VIX plunged 11.06% to 16.40, same logic.

Yesterday’s hawkish shadow from Waller’s debut hasn’t disappeared. The 10-year Treasury yield stood at 4.45%, down 3 basis points from yesterday, but directional pressure remains. Bloomberg’s June 17 headline still reads “Traders See Fed Hike by October,” and media surveys show the long end expected to reach 5% by year-end. Rate hike expectations are still sitting right there — it’s just that today’s geopolitical tailwind and industrial policy noise were louder, temporarily drowning out the monetary tightening narrative.

Sector divergence was extreme. While tech gained 3.04%, financials fell 0.89%, energy dropped 1.65%, and healthcare lost 0.87%. Consumer discretionary rose 1.45% riding tech sentiment, industrials, utilities, and communication services posted small gains, while consumer staples, real estate, and materials weakened. The Dow at 51,564.70 barely moved — dragged down by exactly these legacy sectors.

Individual stocks and credit markets each produced a pricing signal. Meta signed an AI compute deal with data center company Crusoe, expected to secure approximately 1.6 GW of capacity. Moody’s assigned SpaceX its first-ever rating at Baa1, investment grade.

International capital flow data also came in. Japan held $1.2099 trillion in US Treasuries in April, up $18.3 billion from March. China trimmed its holdings slightly to $651.1 billion, a reduction of $1.2 billion. Net international capital inflows to the US totaled $26.1 billion in April, a sharp drop from March’s $150.7 billion, but net long-term capital inflows actually strengthened to $103.1 billion from $81.3 billion in March. Short-term hot money is pulling out; long-duration capital is still coming in.

Today’s price action was fundamentally the monetary tightening narrative yielding to geopolitical and industrial catalysts. The Strait of Hormuz reopening is a tangible supply-side improvement, and the Intel-Apple partnership is an industrial policy signal. But Waller’s hawkish tone hasn’t been disproven — only temporarily overshadowed. If no fresh bullish catalysts emerge next week while rate hike expectations continue to build, whether this rally holds becomes a real question. Two things to watch: whether the 10-year yield reclaims 4.50%, and whether the selling pressure in energy stocks — after oil broke below 75 — bleeds into the high-yield credit market.
