U.S. forces sank Iranian attack boats inside the Strait of Hormuz on Monday in a bid to keep tanker traffic moving. Tehran retaliated by hitting tankers in the same waters. By Tuesday's close, Brent crude was up 5.8% to $114.44, the Dow was down 557 points, and the 10-year Treasury yield had punched through 4.44%. This is the energy shock we've been positioned for.
What happened, in one paragraph
The Strait of Hormuz is the single most important shipping chokepoint on earth: roughly 20 million barrels of crude oil per day — about 20% of global supply — transit a 21-mile-wide passage between Iran and Oman. The U.S. Fifth Fleet operates there to keep traffic moving. On Monday, U.S. forces engaged Iranian fast-attack boats that had moved into the strait. Tehran responded by attacking commercial tankers (no confirmed sinkings, multiple hits). President Trump is publicly threading the needle — he wants negotiation, not bombing — but he has "little choice" after Iran's provocations.
Market read
The simultaneous moves tell you everything:
- Energy up 5%+: Brent +5.8%, WTI +4.5%. Refiners and integrateds caught the bid.
- Equities down: S&P -0.4%, Dow -1.13%. Risk-off, but not panic-off.
- Yields up: 10Y +6.8bp to 4.445%. Inflation fear is winning over recession fear.
- Gold up 1.78%: classic Hormuz hedge.
- Dollar mixed: EUR/USD slightly weaker; the dollar is the partial safe-haven, but not a full one because U.S. is a participant.
Portfolio actions today
We had energy and defense already overweight from Friday. Today we add:
- Schlumberger (SLB) — 2% in 250k/500k. Brent above $114 reignites the upstream re-investment cycle. SLB is the cleanest oilfield-services play.
- +1% to each of XOM, CVX, COP, OXY. The integrateds capture both upstream margins and refining spread.
- GLD 3% → 5% in the conservative model. Gold is exactly what gold is for.
- Hold on LMT, RTX, GD, HII. Already overweight; defense order books don't expand on a single news cycle. They expand on appropriations.
The three scenarios
| Scenario | Probability | Brent target | Portfolio impact |
|---|---|---|---|
| De-escalation in 2 weeks | ~30% | $95–$100 | Trim energy adds; keep defense. |
| Sustained skirmish | ~50% | $110–$120 | Hold today's book; monitor inflation. |
| Strait closure | ~20% | $140+ | Add SLB to 4%; add GLD to 7%; trim discretionary. |
What we are not doing
We are not panic-trimming tech, not aggressively shorting, not buying short-dated VIX. The book is already positioned defensively. The discipline is to let our existing overweights do their work.
Energy + defense in your model
250k model is now 14% energy / 11% defense / 5% gold. 500k model: 16% energy / 13% defense / 5% gold. Conservative model: 8% energy / 6% defense / 7% gold. We'll re-evaluate at the next escalation point.
