The Rotation Started in February. Wednesday Just Made It Visible
Reuters reported Thursday morning that Canadian financials now account for 37% of the TSX composite, the highest share in eight years and up from 31% as recently as March. Since the US struck Iran on February 28, financials have climbed 22%, energy has gained 7%, and materials, which includes the mining stocks that make up most of gold's index representation, has fallen 25%, though miners have clawed back some of that loss in the past week. The Big Six banks now trade at an average 15 times forward earnings, versus 12 times for the top five US banks, the widest premium since 2010.
The Market Desk's account of Wednesday's record close, carried by Shopify and a narrow band of gold miners while Thomson Reuters and Suncor fell despite beating estimates, described a single session. Thursday's data shows that session was not an anomaly. It was one data point in a six-month capital rotation out of the sectors most exposed to the Hormuz war and into the sector least exposed to it. Wednesday's gold miner rally was a partial, week-scale reversal inside a five-month decline in materials. The concentration the Market Desk flagged is structural, not a one-day quirk of the index's weighting.
Financials' share of the TSX composite rose to 37% in August from 31% in March. Miners have recovered part of the materials decline in the past week, a partial reversal inside the broader five-month drop.
The Same Concentration Undercuts the Tax Desk's Rate Math
The Tax and Wealth Desk cited the TSX's 29.46% one-year return as the reason the arithmetic favours a prescribed rate loan right now: invested funds comfortably outrun a 3% borrowing cost. That comparison assumes something close to a diversified Canadian equity bet. An index that is 37% financials, priced at the widest premium to US bank peers since 2010, is a narrower bet than the label "TSX composite" implies. Veritas Investment Research's Shalabh Garg upgraded Canadian banks to market-weight in July, arguing the group is largely insulated from AI-driven disruption and unlikely to face a systemic credit event soon. Raymond James portfolio manager Michael Dehal has flagged the opposite concern: if bank earnings growth cannot keep pace with the current multiple, the price adjustment that follows would weigh on the TSX itself, precisely because financials now carry more of the index's weight than they have since 2018. An advisor recommending TSX index exposure inside a prescribed rate loan structure this quarter is recommending a more concentrated position than the same recommendation would have been in March.
Thursday's Oil Swing Shows the War Premium Hasn't Actually Cleared
WTI jumped to $77.83 a barrel shortly after 5 a.m. ET Thursday, a 3.5% intraday spike, after Yemen's Houthis claimed a new attack on a Saudi tanker in the Gulf of Aden. By late morning it had settled back toward $75, as Iran and Oman moved a narrower shipping-route agreement, covering two to four months and explicitly described by Tehran as short of a full reopening, into final drafting. WTI's daily series, extended through Thursday's whipsaw, sets the two moves side by side.
WTI rose to $77.83 shortly after 5 a.m. ET Thursday on a claimed Houthi tanker attack, then eased back toward $75 by late morning as the Iran-Oman shipping route agreement moved toward final drafting.
The same forces are pricing three different assets in the same direction on the same unconfirmed premise. Gold opened Thursday above $4,300 for the first time since June 17, up more than 4% from Wednesday's own opening level, on the same Hormuz negotiation reports. Financials' 22% advance since February has been supported partly by the market pricing an eventual resolution of the same conflict. None of the three, gold's rally, the bank premium, or Wednesday's TSX record, depends on the strait actually reopening. All three depend on the market's confidence that it will. Thursday's Houthi attack, arriving hours after the Geopolitical Desk's reporting on a near-final deal, is the same pattern that broke the prior near-deal three weeks ago. WTI is pricing the outcome before the outcome exists, in the same underlying asset that has driven every one of this week's desk stories.
