The S&P/TSX Composite touched an intraday record near 35,408 shortly before noon Wednesday, extending a run that has now produced four straight record closes in June. By 2:15 PM, a chunk of that gain was gone. The reversal traces a single cause: the Federal Reserve's 2:00 PM statement and an updated dot plot that leaned firmer than markets had positioned for heading into new Chair Kevin Warsh's first meeting.

The Morning Belonged to Materials

Gold traded above $4,350 an ounce Wednesday, up roughly half a percent on the day and extending a third straight session of gains tied to continued safe-haven flows even as the broader geopolitical premium in oil unwound. That strength carried the materials sector to the top of the TSX leaderboard through the morning session, with gold producers among the standout names as the index pushed to its fresh high.

The move fits a pattern that has held for most of June: a TSX setting records with materials and financials doing the heavy lifting while energy lags. Wednesday was the fourth straight session in that pattern, and the morning high reflected the same mix that has driven each of the prior three.

Energy Could Not Catch a Bid Even Before the Fed

Canadian energy names were already lower well before the afternoon reversal. Suncor traded down toward $79.89, off close to 2% on the day. Cenovus extended a slide sharp enough that some analysts have begun describing the stock as oversold relative to its underlying asset base. Canadian Natural Resources fell more than 1%. The driver in every case was the same: Brent crude sliding toward $78 and WTI below $77, both benchmarks at their lowest levels since early March, as markets priced Friday's scheduled Geneva signing between the US and Iran ahead of the event itself.

That energy weakness was a known headwind heading into Wednesday's session, distinct from anything the Fed did. It explains why the TSX's record was driven entirely by strength elsewhere in the index rather than broad-based participation.

The Fed Statement Changed the Afternoon

The Federal Reserve held its target rate at 3.50% to 3.75%, the outcome nearly the entire market had priced. The reaction was not to the rate. It was to the updated Summary of Economic Projections, which showed nine of eighteen officials now projecting a 2026 rate hike rather than the cut the median forecast had shown as recently as March.

US equity benchmarks turned negative within minutes of the 2:00 PM release. The S&P 500 was down roughly 0.6% by 2:05 PM, the Nasdaq Composite down about 0.7%, and the Dow off roughly 160 points. The two-year US Treasury yield rose nearly 11 basis points to 4.153%, and the 10-year added about 4 basis points to 4.469%. The TSX, already trading off its noon high, extended that decline through the same window, falling from a level near 35,381 just before the announcement to roughly 35,296 by 2:30 PM before stabilizing modestly into the close.

Why the CAD Reaction Matters as Much as the Index Move

USD/CAD weakened the loonie to its softest intraday level in roughly seven months, touching 1.4036 before settling near 1.4030, a 0.3% move on the day. The mechanism is straightforward and compounding rather than singular. Oil's slide has been removing a structural support for CAD for more than a week, as the prospective Iran settlement reduced the energy premium baked into the currency. A Fed that just signalled a firmer rate path adds a second, simultaneous source of pressure, since it widens the yield advantage US assets carry over Canadian ones at the exact moment Canadian energy revenues are also softening.

Neither pressure on its own would be unusual. Both arriving on the same trading day, with the TSX simultaneously sitting at a fresh record before the Fed news landed, is the specific combination that makes Wednesday a session worth holding onto for context rather than filing away as a single bad afternoon.

The composite and its energy sub-index tracked closely through the morning before diverging sharply once the Fed statement landed, with energy extending its existing slide while the broader index found a partial floor on materials strength.

The energy sub-index was already declining through the morning on falling oil prices, independent of the Fed. Both series accelerated lower after the 2 PM statement, with energy losing ground faster than the broader composite.
