The story so far
The first half of 2026 was defined by a war. A US–Iran conflict closed the Strait of Hormuz, sent oil briefly to $120, and pushed inflation back up — harder in America than in Europe. Both central banks reversed course: the ECB hiked for the first time in three years, and the Fed, under a new chair, stopped cutting.
Through all of it, stocks kept climbing, powered by an enormous bet on AI infrastructure whose payoff is genuinely contested. This book explains the machinery, not what to buy. By midsummer the story cooled into data-watching, as a weak June jobs report left the Fed split over whether its next move is a hike or a cut. Two weeks on, a large AI-memory listing put a face on the trade.
Chapter 1 · July 2026
A war, two central banks, and a market that climbed anyway
The macro story of 2026 starts in the Strait of Hormuz. The US–Iran war closed the world’s most important oil chokepoint, briefly spiking Brent crude toward $120 a barrel before a fragile June ceasefire brought it back near $73. That shock pushed US inflation to 4.2% in May, a three-year high, driven almost entirely by energy; core inflation, stripping out food and fuel, was a calmer 2.9%. Europe felt it too but is cooling faster — eurozone inflation eased to 2.8% in June, and Germany’s to 2.3%.
The central banks flipped
Both of the world’s major central banks reversed direction. The European Central Bank raised rates in June for the first time in three years, taking its deposit rate to 2.25%. The US Federal Reserve — now chaired by Kevin Warsh, who replaced Jerome Powell in May after the most partisan confirmation vote in the Fed’s history — held at 3.50–3.75% and signaled that its next move might be a hike, not a cut.
Stocks didn’t care
Despite war and sticky inflation, the S&P 500 sits near 7,490, up about 9% on the year, powered by roughly $690 billion in planned AI infrastructure spending from the big five tech firms. Whether that spending is rational is the market’s central argument, covered on the left. Meanwhile the euro trades near a one-year low around $1.14, and borrowing costs diverged sharply across the Atlantic: American mortgages run about 6.4%, German ones 3.3–3.7%, with German home prices rising again on chronic undersupply.
In the background
Two slow stories are worth watching. The US federal deficit is tracking near $1.9 trillion — about 5.9% of GDP — with interest payments alone now topping $1 trillion a year, a path the government’s own auditors call unsustainable. And crypto finally got its rulebook moving: the CLARITY Act, handing the CFTC authority over digital-commodity spot markets, advanced out of committee toward a Senate floor vote.
The open questions
The AI build-out: bubble or justified?
BubbleCapex is growing far faster than the revenue it should produce — a wider gap than the 2001 telecom bust — and the giants are starting to borrow to fund it.
Forbes JustifiedUnlike 1999, the spenders are the most profitable companies in history and can fund the build from cash flow, while cloud backlogs surge on real demand.
Guinness Global Investors The US deficit: slow-motion crisis or absorbable?
CrisisPeacetime deficits near 6% of GDP are unprecedented, interest already tops $1 trillion a year, and auditors call the path unsustainable.
CRFB AbsorbableThe US borrows in its own reserve currency, markets keep absorbing record issuance with the 10-year near 4.5%, and the likeliest path is slow drift, not rupture.

A soft jobs report reshuffles the Fed’s summer
The third quarter opened with a labor-market wobble. U.S. employers added just 57,000 jobs in June, well under the 110,000–115,000 economists expected, even as the unemployment rate ticked down to 4.2% from 4.3% and average hourly earnings rose 0.3% on the month and 3.5% over the year. A cooling hiring pace alongside still-firm wages is exactly the mixed signal that makes the next policy move hard to call.
Stocks split down the middle
Markets took the weak report in stride, but unevenly. The Dow jumped nearly 600 points — about 1.1% — to a record to start July, while the Nasdaq slid roughly 0.8% as chip stocks extended a sell-off and Tesla fell; the S&P 500 finished close to flat. The rotation away from the priciest AI names, even on an up day for the broad market, is the kind of divergence worth watching.
A divided Fed
The Federal Reserve held rates steady in a unanimous June vote, but the committee is split on where they go next: roughly nine members saw one or two hikes as appropriate for the rest of 2026, while about as many favored holding or even a single cut. The soft jobs data gives the Fed room to stay patient and let the numbers decide rather than commit early.
The open question
Which way does the Fed lean now?
Toward patience or cutsHiring has clearly slowed, and a labor market adding only 57,000 jobs is hard to square with raising rates into it.
24/7 Wall St. Still tilting to hikeWith inflation running above 4% and wages firm, half the committee still sees hikes ahead — one weak month may not be enough to change that.
Schwab Chapter 3 · July 2026
A record listing puts a face on the AI trade
Rather than use a rolling market recap to freeze a fast-moving return, this chapter follows one dated transaction in the AI trade. SK hynix’s final prospectus, filed July 10, records the price and size of its U.S. offering; Nasdaq records when trading began and the opening price. Those are fixed points a reader can check after the market has moved on.
The memory king comes to New York
SK hynix — a South Korean memory-chip maker whose prospectus describes high-bandwidth memory as a core product for AI systems — began trading on Nasdaq under SKHY on July 10. Its final SEC prospectus records 177.9 million American depositary shares offered at $149 each, for a $26.5071 billion public offering price before underwriting costs. Nasdaq says the shares opened at $170 and calls the sale the second-largest U.S. share sale at the time. Claims about oversubscription, a near-$1 trillion valuation and a sevenfold one-year rise are left out because the filing and exchange record cited here do not establish them.
Plumbing, and a pivotal week
Two official calendars set the next checkpoints as this chapter closed. BLS scheduled the June CPI release for July 14 at 8:30 a.m. Eastern, and the Federal Reserve calendar placed Chair Kevin Warsh’s semiannual monetary-policy testimony before the House Financial Services Committee later that day. On crypto market structure, Congress.gov showed the House-passed CLARITY Act still referred to the Senate Banking Committee; it did not establish a July floor vote. No rate-probability estimate is included because the draft did not identify a dated futures contract or calculation.
The open question
What does a record-sized AI-memory listing tell us?
What the record showsInvestors bought 177.9 million ADSs at $149, and Nasdaq recorded a $170 opening trade. That establishes strong demand at the offering; it does not measure future chip demand.
SEC prospectus What remains uncertainThe prospectus itself lists cyclical demand, competition, customer concentration and large capital needs among the risks. A large sale can fund growth without resolving those uncertainties.
