Gold fell to $4,040 on Friday. Oil fell to $68.86, its lowest since February 27. Both moves were caused by the same event: accelerating tanker traffic through the Strait of Hormuz as the U.S. Iran ceasefire appeared to hold. Then over the weekend, Iran struck two more tankers, the U.S. struck back twice, and by Monday morning oil had recovered to $70.53 while gold kept falling, touching $4,040.
An investor scanning headlines this weekend saw the same noun in every story: Strait of Hormuz attack. The instinct is to expect the same asset to respond the same way each time. Gold did not. This is the availability heuristic doing exactly what the research says it does, and the cost of trusting it shows up specifically in how a client reads a four day chart.
The Availability Heuristic Is Reading One Story, Not Two
Kahneman and Tversky's 1973 work on the availability heuristic describes a specific failure: people judge the likelihood and meaning of an event by how easily a similar example comes to mind, not by the actual mechanism producing it. The mechanism here split cleanly into two separate channels, and the heuristic erases the split.
Oil responds to the supply channel. A tanker attack is a direct, physical threat to barrels moving through a chokepoint, so the price moves on flow risk. Gold responds to the policy channel. A regional flare up that raises headline inflation expectations and therefore raises the odds of a Fed rate hike makes gold, which pays no yield, less attractive relative to cash and bonds. The same event pushes the two channels in opposite directions. The investor who has filed away "geopolitical shock, buy gold" from prior cycles is applying a rule that was built for a different rate environment.
What the Client Actually Remembers
This is where recency bias compounds the heuristic. Gold ran from roughly $4,400 in mid June to a four month low near $4,040 by June 26, a decline of close to ten percent in two weeks. A client who bought gold in the spring as a hedge against exactly this kind of weekend has now watched the hedge lose money on the weekend it was supposed to prove itself. The client's lived experience of the last fourteen days, not the underlying mechanism, is what shapes the next phone call.
CME FedWatch data has the probability of a Fed hike by September near 73 percent, up sharply since the June 17 dot plot under new chair Kevin Warsh signalled nine of eighteen officials expected at least one increase this year. That is the actual driver of gold's slide. It has very little to do with whether a tanker was hit on Thursday or Saturday.
Gold's fourteen day round trip against WTI's much smaller net move over the same window shows the size of the divergence in relief.

The Disposition Effect Sets Up the Next Mistake
Shefrin and Statman's disposition effect, the tendency to sell winners early and hold losers too long, has a specific entry point in a moment like this. A client holding gold at a loss relative to its mid June high is now deciding whether to hold through what looks like continued bad news, anchored to the price they paid rather than to where rate expectations are heading. The instinct to wait for gold to "come back" before reconsidering the position is mental accounting, not analysis. The position should be evaluated against the current Fed path, not against the entry price.
The same client may be watching energy holdings rally on the identical weekend's news and concluding that the portfolio's geopolitical hedge worked after all, when in fact the energy exposure and the gold exposure responded to two different transmission mechanisms that happened to point in opposite directions this particular weekend. Crediting the right hedge for the wrong reason sets up a worse decision the next time a chokepoint headline appears and oil does not move the way gold did this time.
The Mechanism Survives the Next Headline, the Pattern Recognition Does Not
Talks between U.S. and Iranian officials are scheduled to resume in Doha on June 30. Whatever happens there will generate another headline that an availability heuristic will try to fold into the same mental file as the last one. The distinguishing question for an advisor having this conversation is not whether the news is good or bad. It is which channel, supply or policy, actually carries this particular piece of news, because that determines whether oil or gold is the asset that should move.
