The Rally Believes a War That Isn't Over

The market spent last week constructing a narrative around a war it decided to declare over. The S&P 500 notched its third consecutive record close on Friday, ending at 7,126. The Nasdaq ran 12 straight sessions of gains, its longest streak since 1992. Brent crude, which had traded north of $110 as recently as two weeks ago, plunged to $90.38 on Friday — down 9% in a single session — after Iran declared the Strait of Hormuz "fully open to commercial traffic" following the Israel-Lebanon ceasefire. Traders bought everything that had been punished and sold every hedge they owned. It felt like a settlement.

Then Sunday arrived.

Overnight, the U.S. seized an Iranian cargo vessel attempting to run the naval blockade. Iran responded by announcing the Strait was closed again and refusing to participate in second-round peace talks. Trump, posting from Mar-a-Lago, warned he would "knock out every single Power Plant, and every single Bridge, in Iran" if Tehran did not agree to Washington's terms. WTI surged 7.8% in Sunday futures trading to $90.38. The stock market's peace dividend — a 12% gain off the March 30 lows — now sits on a fault line.

A Rally Built on Borrowed Assumptions

It's worth slowing down to understand what the market actually priced in last week — because it matters enormously for the week ahead. Equity investors did not buy stocks because the war ended. They bought stocks because the marginal headline skewed toward de-escalation: a ceasefire between Israel and Lebanon, Trump's comment that a deal was "very close," oil reversing sharply off its highs. The inference became the trade. What Steve Sosnick at Interactive Brokers called a "feeding frenzy" was FOMO logic made structural. Nobody wanted to be short into a peace announcement. The problem is: the announcement hasn't come.

The U.S. naval blockade of the Strait of Hormuz remains in place. Trump confirmed as much Friday. Iran's Supreme National Security Council still has not agreed to any framework. What happened Friday was an options expiration event and a short squeeze that produced the visual signature of a peace deal without any of the substance. The market bought the vibe. The vibe may not survive Monday morning.

What the Warsh Hearing Actually Changes

Tuesday at 10 a.m. ET, Kevin Warsh sits before the Senate Banking Committee. His prepared remarks, published in advance, are calibrated to a narrow needle: acknowledge Fed independence without alienating the administration that nominated him, signal rate-cut openness without triggering inflation credibility concerns. The hearing matters less for what Warsh says than for what it reveals about the path to Powell's May 15 exit.

The blocking vote remains Senator Thom Tillis, who has pledged to vote no until DOJ drops its criminal probe into Powell. The Banking Committee split is 12-12 without Tillis, meaning Warsh cannot clear committee. Senate Banking Committee Chairman Tim Scott has said he believes "the DOJ will wrap this up in the next several weeks" — language that implies a deal is being negotiated, not a verdict being handed down. Markets are watching this sub-plot almost as closely as the Hormuz negotiations. An independent Fed with a hawk-leaning chair in a stagflationary environment is one script. A Warsh who signals aggressive rate cuts is an entirely different one.

Earnings Season: The Week That Prices Everything Forward

Over 100 S&P 500 companies report this week. The headline names are Tesla, Boeing, IBM, American Express, Texas Instruments, ServiceNow, Procter & Gamble, Intel, and UnitedHealth — a cross-section of the economy broad enough to function as a proxy referendum on whether corporate America has absorbed the oil shock or merely delayed recognizing it.

Two names carry outsized significance. UnitedHealth has already declined nearly 50% over the past year, with 2026 revenue expected to fall for the first time in three decades. Whatever UNH reports will crystallize healthcare sector sentiment for the quarter. And Tesla, still treated by the tape as a bellwether for consumer discretionary and EV adoption globally, will tell us whether demand destruction from $100+ oil has reached the goods economy or remains confined to gasoline stations.

FactSet data through Friday showed Q1 earnings growth tracking at double-digit rates for the sixth consecutive quarter, with Financials leading on positive revenue surprises. But the forward P/E of 20.9× — above the five-year average — means the earnings bar is already priced. Any guidance cut, particularly from consumer-facing names, will hit disproportionately hard in a tape that has rallied 12% off the lows on geopolitical optimism alone.

The Structural Question the Market Keeps Postponing

The deeper tension that no headline can resolve: the Strait of Hormuz carries roughly one-fifth of the world's oil supply. Even a partial, uneven reopening — which is the most likely near-term scenario — leaves a risk premium permanently embedded in energy costs. That premium is inflationary. It is also deflationary for discretionary spending. The combination is exactly what central bankers fear most: a supply shock that tightens the consumer wallet while simultaneously raising input costs for every goods-producing company in the index.

The market's current read is that the worst is over and we're settling into a $85–95 WTI range with gradual normalization. That may be correct. But it requires a very specific sequence: a Hormuz framework deal within weeks, Iranian compliance, no further escalation from either navy, and an inflation print that confirms oil's decline is flowing through to headline CPI. That is a lot of sequence to price in advance.
