Two of the summer's most consequential developments landed within hours of each other on Monday. Treasury Secretary Scott Bessent unveiled a sweeping sanctions campaign aimed at severing Iran's remaining trade links, and Canada's retaliatory tariffs against the United States moved a step closer to their September 8 start date. The Cboe Volatility Index rose 0.72 points to close at 15.85.
That is the entire market reaction to two live shocks landing in the same week. It is not calm. Amos Tversky and Daniel Kahneman named this exact mechanism in 1973: the availability heuristic. The more readily examples of an event come to mind, the higher people rate its probability of recurring.
When shocks keep arriving without a matching drawdown, each additional shock becomes less available as a felt risk, not more. The market is not concluding the risks have passed. It is losing the ability to notice them.
Twenty-One Trading Days of Compression
The VIX has not cleared 21 since the last week of July. It spiked to 20.66 on July 29, the day three regional Federal Reserve presidents dissented in favour of an immediate rate hike, the first three-way FOMC split since 2016. Within two weeks it fell below 15, and it has stayed in a narrow band since.
That compression held through the collapse of US-Canada trade talks on August 21, the imposition of 50 percent US tariffs on roughly $20 billion of Canadian goods, and Monday's Iran sanctions announcement. Each of these would have been a standalone volatility event a year ago. Together, they moved the index four tenths of a point.
The Cboe Volatility Index has traded inside an eight point range since July 29, and the two heaviest shocks of the summer landed inside that range without pushing it back toward its high.

Bank of America's August 18 Global Fund Manager Survey backs up what the VIX shows. Cash levels among the money managers surveyed fell to 3.5 percent, a reading BofA strategist Michael Hartnett called among the lowest in years, while global equity allocations rose to their highest since late 2021.
The Divergence That Should Worry an Advisor
Gold is not behaving the same way. The metal traded near $4,681 an ounce Monday, within reach of its cycle high, supported by the same Iran sanctions news that left the VIX untouched. Gold is the asset institutional buyers use to hedge exactly the kind of geopolitical escalation the VIX is currently ignoring.
That divergence, an equity volatility gauge sitting near a one year low while gold sits near a record, is the availability heuristic operating on two different investor populations at once. Equity positioning reflects a market that has stopped updating on Iran and trade headlines. Gold demand reflects buyers who have not.
What Would Actually Move It
Two events this week test whether the compression holds. Federal Reserve Chair Kevin Warsh delivers his first Jackson Hole keynote Friday, three weeks ahead of a September FOMC meeting where markets currently price roughly one in three odds of a hike. The Bank of Canada's own decision follows on September 2, widely expected to hold at 2.25 percent.
Neither event needs to surprise markets to matter. The recalibration point is what matters, not the surprise itself. A single reminder that these risks were never resolved, only unpriced, is enough to move the felt probability back toward where the fundamentals already sit.
