When markets bounce on ceasefire optimism, a well-documented psychological mechanism pushes investors toward a mistake they will regret the moment the next headline arrives.

WTI below $100 and core CPI at a five-year low handed the Bank of Canada its clearest signal yet. The bond market saw it. The currency saw it. The equity market told a more complicated story than the headline suggested.

Energy gained 2.3%. Mining lost between 2% and 6%. Financials dropped. Tech retreated. The index nearly flat is an arithmetic accident produced by one sector offsetting everything else. The US 30-year yield at a 19-year high is what drove the session.

Saudi Arabia, Qatar, and the UAE convinced Trump to stand down from a planned Tuesday strike on Iran. The ceasefire is alive. The Strait of Hormuz remains closed. For Canadian energy investors, the calculus depends on which scenario resolves this standoff: a deal in weeks, or stalemate through the summer.

Core inflation cooled to 2.1% in April, handing the Bank of Canada the cover it needs to hold at its June 10 meeting. The harder question is the one the data does not answer: the Bank's April MPR assumed Brent oil at $90. It is at $111.

The first session back from Victoria Day opens with a below-consensus CPI print, a Brent selloff on the Iran postponement, and a GoC 10-year yield at a two-year high. Three sectors are pointing in three different directions.

Trump called off a planned Iran strike overnight. Brent fell 2%. The structural impasse between Washington and Tehran remains exactly where it was, and the Hormuz timeline for Canadian energy portfolios has not changed.

The TSX shed 435 points on May 15 as a global bond rout and stalled Hormuz talks punished miners, banks, and rate-sensitive names. Energy was the lone sector standing. The TSX is closed today for Victoria Day. Tuesday opens with April CPI and the Iran NSC meeting outcome landing simultaneously.

Trump convened a national security review of military options against Iran on Sunday. A meeting with advisors is scheduled for Tuesday. The IRGC has threatened to "deactivate" US Gulf bases. Day 80 of the Hormuz closure arrives with the ceasefire visibly fraying — and with it the oil premium that has driven every major market move of 2026.

Statistics Canada releases April inflation data on May 19 — the first reading after the carbon levy base-effect clears and the first test of whether the March energy shock is feeding into broader price pressures. The Bank of Canada's May 13 deliberations identified the precise conditions that would shift its rate path.

Eleven weeks of elevated crude has recalibrated what investors call "normal." The research on anchoring explains why that shift is dangerous — and why the most costly portfolio decisions of 2026 are still ahead.

The Trump-Xi summit produced framework language, not Hormuz progress. Kevin Warsh inherits the Fed chair today into an oil-at-$103 inflation environment. The traditional safe haven trade inverted. The implication for Macklem's June 3 decision is not what the morning frameworks could have seen.

U.S. futures are down sharply on summit disappointment. Brent crude is up 2% above $107. The TSX faces a split-market session: energy names should outperform while technology and rate-sensitives take the hit. The Canadian read is more complicated than the headline suggests.

The Trump-Xi summit ended without China committing to pressure Iran on the Strait of Hormuz. Peace negotiations are on life support. For Canadian portfolios, the geopolitical story is now about how long the oil premium persists, and what that means for the Bank of Canada's June 10 calculus.

The TSX fell 0.5% Wednesday as technology names dropped 2% to a one-month low while energy stocks held steady above $100 oil. The divergence tells a specific story about how the Canadian market is pricing the Hormuz supply shock versus the inflation-driven rate re-rating.

The Strait of Hormuz has been effectively closed to normal commercial traffic since late February. Seventy-six days in, the IEA says the market will remain significantly undersupplied until October even if the conflict ends next month. The Canadian portfolio implications run deeper than the oil price.
