May 28, 2026 | Issue #17 | Day 90 of the Iran war

Iran escalation. President Trump on Wednesday rejected a report that he was close to a compromise deal with Tehran, said Iran was "negotiating on fumes," and left open the possibility of ordering U.S. forces to "go back and finish it" (CBS). Early Thursday, a U.S. official said the military shot down four Iranian drones and struck a ground control station near Bandar Abbas; Iran's Revolutionary Guard said it retaliated against a U.S. air base, and Kuwait, which hosts a large U.S. base, said it intercepted an incoming attack (Reuters). The early-April U.S.-Iran ceasefire is under growing strain.

Markets. All three major U.S. indexes closed at record highs together on Wednesday for the first time in 2026: the Dow at 50,644.28 (+0.36 percent), the S&P 500 at 7,520.36 (+0.02 percent), and the Nasdaq Composite at 26,674.73 (+0.07 percent). Stock futures fell Thursday morning as the strikes resumed and inflation data landed.

Energy. West Texas Intermediate was around $90.26 per barrel and Brent around $95.92, each up roughly 1.7 percent intraday Thursday, rebounding after a Wednesday drop of about 6 percent that followed a since-rejected report of a Hormuz framework deal (CNBC). Brent is down roughly 12 percent over the month on deal hopes.

Inflation. The Fed's preferred gauge, the April PCE price index, rose 0.4 percent on the month and 3.8 percent from a year earlier, the highest since May 2023, driven by the Strait of Hormuz energy shock (BEA). Core PCE rose 0.2 percent on the month and 3.3 percent annually. Both monthly prints came in a touch below consensus.

Federal Reserve. Traders now price the Fed's next move as possibly a rate increase, with no cut expected through the rest of 2026, under new chair Kevin Warsh, sworn in May 22 by President Trump (CNBC). The 30-year Treasury yield was near 5.02 percent and the 10-year near 4.50 percent at midweek, down from the roughly 5.2 percent on the 30-year reached May 20.

Lebanon. Israel ordered the forced displacement of Tyre, one of Lebanon's largest cities, and surrounding areas, then began striking what it called Hezbollah targets; it declared all areas south of the Zahrani River combat zones (Al Jazeera). Prime Minister Netanyahu said a large ground force was pushing in to "fortify" a security zone. More than 1.2 million Lebanese are displaced; the April 16 U.S.-brokered truce has not held.

Earnings. Snowflake surged about 37 percent after beating and raising guidance, paired with a $6 billion commitment to Amazon Web Services. Best Buy rose about 8.4 percent on an earnings beat. Dell gained nearly 4 percent after winning a $9.7 billion Defense Department contract and reports after the close; Costco also reports tonight. Salesforce guided lighter on the year (TheStreet).

AI and chips. Memory leader Micron was up roughly 73 percent month-to-date on AI demand. The May 20 Nvidia blockbuster carried SoftBank, Arm, and Qualcomm sharply higher in the days after.

Gas. The AAA national average was $4.49 per gallon as of May 26, down 4 cents on the week but still near four-year highs and $1.32 above a year ago.

War powers. House Republican leaders pulled a planned war powers vote and delayed the matter into June after a Democratic resolution to compel withdrawal appeared to have the votes to pass, with Rep. Jared Golden signaling he would now support it (NPR, CBS).

For the first time in 2026, the Dow, the S&P 500, and the Nasdaq all closed at record highs on the same day. They did it Wednesday, the same session in which crude fell about 6 percent on a report that Iran would restore traffic through the Strait of Hormuz as part of a framework deal with Washington. By Thursday morning the report was dead. Trump rejected it, said Iran was "negotiating on fumes," and left open ordering forces to "go back and finish it." The U.S. struck a drone control station near Bandar Abbas, the Revolutionary Guard hit a U.S. air base, Kuwait reported intercepting an attack, oil rebounded, equity futures fell, the dollar rose, and gold dropped. The market had priced a peace the war had not signed.

That is the board-level fact of the week, and it is different from last week's. Issue #16 framed two ceilings pressing at once: the war's resolution and the bond market. The bond ceiling has eased on the surface. The 30-year has come off its May 20 peak near 5.2 percent to roughly 5.02 percent, Brent is down about 12 percent on the month, and pump prices have slipped to $4.49. Each of those moves was a bet on a deal. The melt-up to simultaneous records was the same bet, amplified by an AI complex that has run hard since the May 20 Nvidia print. Wednesday was the bet's high-water mark. Thursday was the reminder that the underlying event has not occurred.

The bet is not unreasonable, but it is a bet. Both sides remain apart on the two issues that matter most, Iran's nuclear program and its control of the strait, and the ceasefire that took effect in early April has been violated repeatedly by both sides. The thing markets discounted, a signed and durable reopening of Hormuz, is precisely the thing the parties have not agreed. Meanwhile the inflation that any deal is supposed to relieve printed at 3.8 percent on the headline PCE, the highest in three years, and traders have moved from pricing Fed cuts to pricing a possible hike. A deal would help oil and sentiment. It would not obviously move a 30-year yield that is being driven by inflation persistence, the fiscal trajectory, and the new Warsh framework.

The board question is not whether to believe the rally. It is whether the company's plan has quietly been rebuilt on the assumption the rally encodes: that the war ends soon, oil normalizes, and conditions return to the pre-war baseline. That assumption is now sitting inside asset prices at record highs. The war just tested it.

1. Record highs are priced for a resolution that has not been signed. The simultaneous all-time highs Wednesday discount a Hormuz reopening and a wind-down that the parties have not agreed and that Thursday's strikes pushed further out. The gap between the market's central case and the conflict's actual state is the exposure. Directors should ask whether the company's 2026 plan, hedging book, and resumed-war scenario have been re-baselined since Wednesday's close, or whether they have been allowed to drift toward the optimistic case the market is now quoting. The cheapest insurance is bought when the market is priced for peace, not after the next escalation reprices it.

2. The index is carrying a concentrated AI and chip bet. The path to records ran through Nvidia, Snowflake, Micron, and the memory complex, not through breadth. Micron alone is up roughly 73 percent on the month. For boards, this cuts two ways. Companies on the build side or the consumption side of AI are riding a thesis that is now doing the heavy lifting for the whole tape; companies outside it are nonetheless exposed through index funds, treasury allocations, and customer concentration. Directors should know how much of the company's own enterprise value, and its pension and treasury exposure, rides on the AI capex thesis holding through a higher-rate, higher-oil environment.

3. Inflation at 3.8 percent has moved the Fed conversation from cuts to hikes. April headline PCE reached its highest level since May 2023, and core held at 3.3 percent, even as both monthly prints came in slightly below consensus. Traders now see the next Fed move as possibly an increase, with no cut expected this year. The financing assumptions embedded in long-cycle capital plans, refinancing schedules, and covenant headroom should be stress-tested against a Fed that hikes rather than holds. The board treasurer's report should state plainly which 2026 and 2027 commitments were underwritten to a cut that is no longer the base case.

4. The constitutional question on the war slid into June, and toward passage. House Republican leaders pulled a planned war powers vote rather than lose it; the Democratic resolution to compel withdrawal appears to have the votes, and at least one prior Democratic holdout has flipped. Trump would still veto, and no war powers resolution has ever overcome a presidential veto. But a resolution that passes a chamber for the first time changes the political ceiling on the strike option that Thursday's "go back and finish it" language invokes. Boards with Middle East operations or defense and dual-use exposure should track the June calendar as a genuine inflection, not a procedural footnote.

5. "After the war" is not a clean line for operations. Even a signed deal leaves two open fronts. In Lebanon, Israel has ordered the forced displacement of Tyre and declared everything south of the Zahrani River a combat zone under a truce that is not holding, with more than 1.2 million people displaced. Beneath the strait, Iran is asserting sovereignty over the subsea cables that carry regional internet and financial traffic, with proposed fees and Iranian-only repair rights. Both persist independent of any Hormuz reopening. Directors whose continuity plans assume that a deal restores the pre-war operating environment should separate the war's end from the regional conditions that will outlast it.

The records on Wednesday did not require a board vote, and neither did the optimism they encode. Optimistic assumptions enter a plan quietly: a hedge not renewed, a refinancing nudged later, a resumed-war scenario softened because the deal "looks close." The question forces the team to find where the market's peace has been imported into the company's own numbers, and to decide on purpose whether to keep it there. Thursday's strikes are a free stress test of the answer.

Next week's Board Brief (Issue #18, June 3) will cover: whether the ceasefire survived the weekend, the bond market's response to the 3.8 percent PCE print and Fed-hike pricing, the Dell and Costco read-through on AI capex and the higher-income consumer, the June war powers calendar, and the Lebanon ground operation.
