Iran's safe passage guarantee for commercial shipping has a literal expiration date, Israel has not signed on, and a $24 billion dispute remains open. None of that is in this week's oil price.

The disposition effect predicts how clients will misread both moves, and it is not the same mistake twice.

The Hormuz MOU and a hawkish Fed dot plot arrived at the same time. The TSX did not average them. It picked a side.

The TSX dropped 0.75% to 35,125 Wednesday as energy and gold miners absorbed a collapsing oil price while new Fed Chair Kevin Warsh delivered a hawkish surprise that hit banks too.

WTI has fallen nearly 30% since the Hormuz memorandum was signed. On June 17, Trump warned bombing could resume. The market has not adjusted, and that gap is the tail risk Canadian portfolios are not pricing.

WTI has fallen from a war-era anchor above $100 to the mid-$70s in days, while a hawkish Fed surprise hit equities on the same week. Clients are processing two opposite shocks as one signal, and that confusion has a name.

Falling oil was supposed to be the good news story today. By 2pm it had become the second blade of a two-sided squeeze on the Canadian dollar, and almost nobody framed it that way.

The composite touched roughly 35,408 in the late morning, its fourth straight June record, before a firmer-than-expected Fed signal pulled the index down through the early afternoon. Materials held the gains. Energy gave back ground it had already lost this week.

WTI has fallen below $77 and Brent below $79 on the prospect of Friday's Geneva signing. The gap between that price move and the physical reality of restoring tanker traffic is the risk Canadian energy investors are not pricing.

Oil collapsed 4% on the ceasefire. The five-year GoC barely moved. That gap is the most important signal in the Canadian market today, and nobody is talking about it.

The TSX closed at 35,297 on June 15, a fresh all-time high, while Suncor fell 3.2% and WTI dropped more than 5%. A record set on a day when the index's largest commodity sector declines is not a uniform rally. It is a structural rotation, and it changes what the second half of 2026 looks like for Canadian portfolios.

The US-Iran agreement signed June 15 ends the blockade phase and begins a 60-day nuclear negotiation window. For Canadian portfolios, the immediate read-through is lower oil, a recovering loonie, and a BoC that can finally look past its inflation constraint. The tail risk is that the deal does not hold.

Oil down 5.5%, the 5-year yield at 3.01%, and the inflation constraint evaporating in real time. But the Fed meeting Wednesday changes the calculus before Macklem can act.

The Iran deal drove global markets sharply higher Monday morning. But the TSX is split: energy names are selling off while financials and rate-sensitives surge. Understanding the rotation is the analysis.

Trump and Iran announced a framework overnight. The signing is Friday in Switzerland. The Strait of Hormuz will not normalize for months. Canadian portfolios need to hold both of those facts at once.

When geopolitical relief arrives, investors don't exhale. They reach for yield. Research on the overreaction cycle explains why the most dangerous moment is right now.
