Markets shrug off U.S.-Iran strikes as earnings season opens
The S&P/TSX Composite closed up 116 points on Monday while the S&P 500 gained half a percent. Not the behaviour you'd expect on a day when U.S. jets hit Houthi targets in Yemen and Iranian state media confirmed American strikes on weapons facilities near Tehran.
Markets ignored the headlines. Or more precisely, they priced them as noise.
The simplest explanation is that investors have watched this movie before. October 2023 brought the initial Hamas attack. November brought Houthi disruptions in the Red Sea. January 2024 saw direct U.S. strikes on Houthi positions. February brought more. Each time, oil spiked for a few sessions, defence stocks ticked up, and then everything reverted. The pattern trained the market to treat Middle East escalation as a headline risk that doesn't consistently translate into earnings risk. So when Monday's strike news hit the tape, the reflex was to buy the dip, not flee to Treasuries.
Earnings season absorbs the oxygen
The other reason Monday's geopolitical flare-up got downplayed is simple timing. Earnings season opened this week. The big Canadian banks report starting Wednesday. In the U.S., the financials kick off Thursday. When quarterly results are about to hit, markets care more about what JPMorgan's net interest margin did last quarter than what happened in the Strait of Hormuz last night. It's not that Iran doesn't matter. It's that it matters less than whether North American consumers kept spending through December.
An iA Financial advisor quoted in the Monday session wrap framed it plainly: markets are "downplaying" the Middle East developments. That's not complacency in the behavioural sense. It's probability-weighting. The range of outcomes from a limited U.S. strike on Iranian weapons infrastructure is wide, but the modal outcome, the one the market assigns the highest likelihood, is that nothing structurally changes. Iran responds with a statement. The U.S. calls it contained. Oil wobbles but doesn't break $90. Equities resume pricing corporate fundamentals within 48 hours.
That modal outcome has been correct often enough over the past 18 months that it's now the default.
What would actually move the needle
The scenario that would break this pattern is the one where something in the supply chain actually snaps. A closure of the Strait of Hormuz lasting more than a few days. A sustained disruption to Saudi or Kuwaiti export terminals. A direct hit on energy infrastructure that takes offline a meaningful percentage of global crude supply for weeks, not days. Those are tail risks. They would reprice everything. But Monday's strikes didn't trigger any of them, and the market behaved accordingly.
Canadian investors have an added layer of insulation here. The TSX energy-heavy weighting means geopolitical oil shocks often show up as a net positive in the index, at least in the near term. If crude rallies on supply-disruption fears, Canadian producers benefit. That dynamic flipped the usual risk-off reflex. Instead of defensiveness, you got modest gains led by the same sectors that would benefit from sustained crude strength.
So the headline "markets shrug" is accurate, but it's worth naming what the shrug actually consists of. Not ignorance. Not recklessness. A calculated bet that this escalation will follow the script of the last five, and that the thing worth watching this week is whether bank earnings show consumer stress, not whether Tehran's next move includes closing a shipping lane.
