The composite touched a fresh intraday record near midday, minutes before the Fed delivered a tone investors were not positioned for. The research on what happens between the high and the headline is specific and well documented.

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.

The US-Iran ceasefire removes the primary inflation risk the Bank of Canada has been managing around since February. The June 22 CPI print, the first under updated basket weights, will tell the Bank whether its "look-through" on energy inflation was vindicated or whether pass-through has already embedded in core.

Canadian energy names have shed 20-plus percent from their 2026 peaks in two weeks. For clients holding appreciated oil sector positions inside CCPCs, the capital gains inclusion rate and the timing of any disposition decision are suddenly back in play.

WTI crude has fallen more than 23% from its 2026 peak in two weeks. Clients who rode Canadian energy stocks from February to June are now facing a decision the research says they will almost certainly get wrong.

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.

The June 10 hold statement left Governing Council a live wire in both directions. The US-Iran deal this morning cuts one of them. What the peace framework means for the July 15 decision and the Canadian rate path.

The peace announcement changes the oil inflation calculus precisely when 1.8 million Canadian mortgages are hitting their renewal peak. The planning implications are time-sensitive.

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.

WTI's 3% drop on Iran deal proximity is not the Market Desk story today. It is the Economy Desk story for July 15, and the Bank of Canada's communications framework has not caught up yet.

WTI dropped 4% premarket Friday. The S&P 500 added 1.75% Thursday. Nasdaq jumped 2.54%. The TSX faces the same sector rotation it saw in April, only this time the war premium has further to unwind.

Trump cancelled Thursday's strikes and said a deal is basically done. Brent fell below $86. The Hormuz re-rating that lifted Canadian energy for three months is now running in reverse.
