Oil Shock Meets Earnings Season: What Actually Moved Markets This Week

The single biggest story of the past week wasn't an earnings beat or a Fed leak — it was a tanker chokepoint. When the U.S. reinstated its blockade of the Strait of Hormuz and Iran responded with fresh strikes, Brent crude jumped 9.6% in a single session to $83.30 a barrel, its best day since May 2020, while the S&P 500 fell 0.79% and the Nasdaq dropped 1.55%. That's the kind of move that reminds you macro risk hasn't disappeared just because earnings season is humming along.

The Hormuz Shock Reset the Narrative

For most of the year, the market's story has been AI capex and resilient consumer spending. This week, geopolitics forced its way back to the top of the list. Trump's announcement that the U.S. would reimpose the blockade and charge a 20% fee on cargo shipped through the strait sent both Brent and WTI crude surging roughly 9%, with WTI settling near $78. Stocks and bonds fell together — a classic sign that the market was pricing in an inflation risk, not just a demand shock. Energy names were the one clear beneficiary, catching a bid as traders priced in tighter supply and higher shipping costs.

The knock-on effect matters more than the headline. Higher oil directly threatens the disinflation trend the Fed has been leaning on to justify holding rates steady, which is exactly why this shows up again in the next section.

Semiconductors Bore the Brunt of the Selloff

Chip stocks led the week's weakness, with SK Hynix's slide spilling over into the broader semiconductor complex as the Hormuz tensions escalated. That's a reminder that the AI-and-chips trade, which has powered most of this year's gains, is also the most crowded and most vulnerable to a risk-off shock. When energy and geopolitical risk spike, high-multiple growth names — semis especially — tend to give back gains first, even if their underlying earnings trajectory hasn't changed.

Underneath the Volatility, the Earnings Backdrop Is Genuinely Strong

It's worth separating the macro shock from the fundamentals. S&P 500 earnings are on track to grow around 24% this year, a pace not seen outside of post-recession rebounds, and the first wave of Q2 reports has come in mostly solid. That's the tension defining this market right now: a genuinely strong earnings cycle running into a geopolitical and inflation risk that could force the Fed's hand. Neither story cancels the other out — they're both true at the same time, and next week's data and earnings will tell us which one dominates.

The Fed Meeting Just Got More Interesting

Going into July, the consensus was a straightforward hold. That consensus is now shakier. With oil spiking and inflation still running above the Fed's 2% target, CME's FedWatch tool showed the odds of a quarter-point hike at the July 29 meeting rising to 46.5% — nearly a coin flip against the base case of no change. The Fed's decision on July 29 is a non-SEP meeting, meaning no updated dot plot or economic projections, so the post-meeting statement and press conference will carry outsized weight for how markets read the Fed's tolerance for an oil-driven inflation bump. The GDP report lands the very next day, July 30, adding a second high-stakes data point in 48 hours.

What's on the Calendar Next Week

• Alphabet and Tesla report after the close on Wednesday, and their results will help set the tone for the broader semiconductor and AI-capex trade heading into the Fed meeting.
• Intel reports Thursday after the close; analysts are looking for roughly 22 cents per share versus a year-ago loss, with revenue expected near $14.4 billion, up about 11.6% year-over-year. Susquehanna's Christopher Rolland recently raised his price target on the stock, citing improving server demand.
• Watch whether energy prices stabilize or keep climbing — that single variable now has more influence over the Fed's July 29 decision than almost anything else on the calendar.

This is not financial advice — always do your own research before making investment decisions.

The Takeaway

This week showed how quickly a strong, earnings-driven market can get knocked off its footing by a geopolitical shock that hits energy prices directly. The underlying corporate fundamentals — 24% earnings growth, solid Q2 reports so far — haven't broken. But the path to the July 29 Fed decision just got a lot less predictable, and semiconductor stocks in particular are likely to stay the most reactive part of the market to any further escalation around the Strait of Hormuz. Big tech earnings from Alphabet, Tesla, and Intel next week will be an early test of whether fundamentals or macro risk wins out heading into the Fed meeting.
