Hormuz on the Edge: Trump Kills the Iran Deal, Oil Climbs
President Trump just killed the Iran ceasefire, and markets woke up to the bill: futures pointing to a negative open, WTI crude holding near $85 a barrel, and the 10-year Treasury yield pressing 4.72%. The June memorandum of understanding — a 60-day window to negotiate a lasting peace and reopen the Strait of Hormuz — expired Monday, and Trump's one-word answer to a renewal was 'no.' That's the macro weight bearing down on a session that already has Home Depot earnings in hand.
Monday's session closed with the S&P 500 at 7,745.06 (−0.52%), the Dow at 53,459.78 (−0.51%), and the Nasdaq at 26,644.91 (−0.32%), as oil climbed and Treasuries sold off after Trump signaled no interest in extending a soon-to-expire Iran ceasefire. Overnight, he made it official — no renewal — leaving the Strait of Hormuz standoff unresolved and WTI holding near $85 a barrel. The 10-year Treasury yield is pressing 4.72%, near a 19-month high, as bond markets price in prolonged energy-driven inflation. Equity futures are lower across the board (S&P futures −0.41%, Nasdaq 100 futures −0.76%) with Polymarket giving only a 27% chance of a positive open. The lone premarket bright spot: Home Depot beat Q2 estimates on revenue ($47.9B vs. $47.3B expected) and adjusted EPS ($4.92 vs. $4.73 consensus), with comps up 1.7% — its best comp since Q3 2022 — and shares rose 2% premarket. The consumer story, however, stays contested: foot traffic fell, customers skewed to smaller projects, and Walmart, Target, and Lowe's still report later this week.
Iran Truce Expires, Crude Climbs, Bonds Sell Off — Three Drivers Hit at Once
President Trump flatly rejected extending the 60-day US-Iran memorandum of understanding, which technically expired Monday. WTI crude rose 0.6% to near $85 a barrel during Monday's session as oil prices climbed on dimming peace prospects. Brent ended Monday above $90. The Strait of Hormuz — through which roughly 25% of global seaborne crude and 19% of global LNG passed in 2025 — remains contested, with tanker attacks and stalled negotiations keeping a structural premium in energy prices.
Treasuries sold off sharply alongside the oil move. The 10-year yield closed Monday at approximately 4.72%, near a 19-month high. Concern is no longer just about the Fed — it is also about fiscal supply and the inflationary tail risk of a prolonged Hormuz blockade. University of Michigan year-ahead inflation expectations hit 4.3% in August, a fifth consecutive month above 4%, adding pressure to the long end of the yield curve.
Home Depot reported Q2 2026 results before Tuesday's open: revenue of $47.9 billion beat the $47.3 billion consensus, and adjusted EPS of $4.92 cleared the $4.73 estimate. Comparable sales rose 1.7% — ahead of the 0.9% expected — the company's strongest comp since Q3 2022. HD shares rose roughly 2% in premarket trading. Note: the beat versus consensus was meaningful but not outsized, driven by genuine volume in outdoor categories rather than one-time items.
The Ceasefire Wasn't Just a Peace Deal — It Was the Market's Inflation Anchor
When the US and Iran signed their June memorandum of understanding, markets quietly exhaled. Oil pulled back from its 2026 peaks. Inflation expectations softened. The Fed's rate-hike calculus looked less urgent. That relief trade is now being unwound in real time.
Trump's refusal to extend the agreement does not mean imminent military escalation — but it means the Strait of Hormuz stays in limbo indefinitely, with no mechanism to restart formal negotiations. For markets, the Strait is not just a geography lesson; it is a price lever. Roughly one in four barrels of seaborne crude transits that chokepoint. With the naval blockade continuing and tanker attacks still occurring, the global energy supply chain remains structurally tighter than it was before February 2026. That keeps headline inflation elevated, keeps the Fed cautious about cuts, and keeps long-end Treasury yields bid upward.
The 10-year yield near 4.72% is not just a borrowing cost — it is a discount rate for every equity valuation on the board. The S&P 500 sits roughly 0.5% below its all-time closing high of 7,798.99, set just last Thursday. That proximity to a record while rates surge is a tension the market has to resolve, and today may be where it starts.

Higher-for-Longer Just Got a Geopolitical Co-Pilot
The 10-year yield near 4.72% reflects two compounding pressures: the Fed's reluctance to cut while inflation stays above 3%, and a term premium bid by fiscal supply and geopolitical uncertainty. A ceasefire breakthrough would be the most potent near-term rate catalyst — not a Fed pivot. Watch the 4.75% level, which has been tested as a 19-month ceiling.
The S&P 500's resilience near record highs despite 4.7%+ yields is entirely a function of AI-driven earnings growth. Q2 S&P 500 earnings are on pace to rise roughly 43% YoY per Zacks estimates (or ~50% YoY per FactSet), with Tech contributing the lion's share. That cushion exists — but it is not infinite. If yields keep climbing and energy costs re-accelerate, multiple compression becomes the path of least resistance.
National average gasoline prices have already climbed to over $4.00/gallon. Consumer sentiment dropped to 51.0 in August — down from 55.2 in July and near a historic low — with year-ahead inflation expectations at 4.3%. July retail sales fell 0.6% MoM, a significant miss. The consumer is not broken, but they are clearly rationing. Home Depot's result (smaller projects, fewer trips) is a micro-confirmation of that macro signal.
Three things this week: (1) Wednesday's FOMC minutes — especially any language on the inflation trajectory and the dissent dynamic around rate hikes; (2) Walmart's Thursday report and its read on trade-down behavior; (3) any diplomatic signal from Iran or the Gulf states that restarts a Hormuz negotiation framework.
Wednesday's FOMC minutes. Cleveland Fed President Beth Hammack has been explicit that the Fed should raise rates now. If the minutes reveal broader sympathy for that view inside the committee, expect the 10-year yield to break above 4.75% and equities to reprice sharply lower.
Energy Wins, Tech Holds, Consumer Discretionary Waits for Its Verdict
The only sector with a clear structural tailwind from the geopolitical backdrop. WTI near $85 and Brent above $90 keeps energy company cash flows elevated. The sector was up nearly 6% week-to-date through last Thursday's close. With no ceasefire extension, that bid stays intact unless a diplomatic breakthrough materializes out of nowhere.
The sector is caught between two vises: high gasoline prices squeezing household budgets and rising long-term yields compressing valuations. Home Depot's beat is encouraging, but comp transaction volume actually fell 1.0% QoQ — consumers came less often and spent more per trip. That is not a growth story; it is a mix shift. Target (reporting Wednesday) and Walmart (Thursday) will tell us whether discretionary spending is holding or cracking.
Tech (XLK) is up more than 7% month-to-date through last Friday and has been the primary engine of S&P 500 earnings growth in Q2. But Nasdaq 100 futures are down 0.76% this morning — more than the broader market — suggesting the sector is not immune to rate-driven multiple pressure. AI spending narratives remain intact, but the sector needs rates to stabilize to sustain its premium valuation.
Geopolitical Risk Is No Longer a Background Variable — It's the Thesis
The Iran-Hormuz story is a real-world illustration of how geopolitical risk flows through commodity markets, into inflation, into central bank behavior, and finally into asset prices. Knowing that transmission mechanism — and being able to explain it in an interview — is a genuine differentiator right now.
Clients with concentrated energy exposure are sitting on outsized gains. The conversation this week is whether to harvest those gains or ride the geopolitical premium longer. The counter-argument: energy-driven inflation erodes real purchasing power across the rest of a portfolio. That tradeoff — tactical energy upside vs. structural inflation drag — is exactly the kind of multi-dimensional discussion that distinguishes a good advisor. Be ready to talk through it.
Home Depot's result is a textbook exercise in reading through a beat. Adjusted EPS of $4.92 cleared consensus of $4.73 — but operating margin actually slipped from 14.5% to 14.3% YoY, and SG&A grew 8.5% YoY against 5.7% revenue growth. The beat was real, but the margin trend is worth flagging. For analysts covering consumer discretionary, the question to model is how a prolonged elevated energy cost environment flows into comp transaction counts over the next two quarters.
Geopolitical uncertainty freezes deal-making — CEOs don't sign large acquisitions when their input cost outlook has a binary geopolitical outcome attached to it. Watch for the Hormuz resolution (or non-resolution) to function as a gating factor for M&A activity in energy, industrials, and logistics. If the standoff extends into Q4, expect more "wait-and-see" postures from corporates, which translates directly into deal pipeline softness. Conversely, a ceasefire breakthrough would be a significant catalyst for transaction activity.
Three Questions You Should Be Ready to Answer This Week
- "Walk me through how an oil price shock affects the equity market." — The answer is not just "energy stocks go up." It's a transmission chain: higher oil → higher input costs and gasoline prices → weaker consumer spending → lower revenue expectations → lower earnings forecasts → multiple compression driven by higher inflation expectations → higher long-end yields → lower present values. Be specific about each link.
- A strong answer on Home Depot acknowledges the top-line beat and comp strength, but also flags the margin compression (operating margin 14.3% vs. 14.5% a year ago, SG&A growing faster than revenue) and the drop in transaction count (−1.0% comps QoQ). Saying "Home Depot crushed it" without those nuances signals you read the headline, not the 10-K.
- "What would you watch to know if the Fed will hike in September?" — Point to three things: Wednesday's FOMC minutes (committee tone on the inflation trajectory), the September CPI print, and energy prices. If Hormuz stays closed and oil re-accelerates, the hawks' argument strengthens regardless of soft retail data.
- Do not say: "The market dropped because of geopolitical uncertainty" — that is the headline, not analysis. Connect the uncertainty to the specific asset prices it moved and explain why through the mechanism, not the mood.
A bear steepener is a yield curve shift in which long-end yields rise faster than short-end yields, causing the curve to steepen while bond prices fall across the board (hence "bear"). It typically signals that markets are pricing in higher inflation or growing fiscal risk over the long term — not necessarily an imminent rate hike at the short end. Today's environment is a textbook bear steepener in action: the 10-year Treasury yield is pressing 4.72%, near a 19-month high, driven by persistent energy-inflation fears from the Hormuz standoff and rising fiscal supply, while the 2-year yield has moved less dramatically. When an interviewer asks you to describe the current yield curve dynamic, this is the term and the logic to reach for.
Sound Prepared Before the Open
"The Iran ceasefire expiry is the real story this morning — not the Home Depot beat. Trump's refusal to extend the MOU means the Strait of Hormuz standoff has no diplomatic runway left, and that keeps a structural premium in oil that the Fed can't ignore. The 10-year yield near 4.72% is the market pricing that inflation risk into the long end. Home Depot's result tells us the consumer is still spending, but selectively and on smaller-ticket items — which is exactly the kind of softening that makes Walmart's Thursday report the more important read on where the American consumer actually stands."
