A Flock of Black Swans

How Many Surprises Does It Take to Spook the Market?

Markets do not usually fall apart because of a single surprise. More often, they unravel when one shock lands on top of another. That is what investors mean when they begin to worry about a Flock of Black Swans. It is not just one rare, destabilizing event. It is a cluster of low-probability, high-impact risks arriving close together and dialing up the FUD (Fear Uncertainty and Doubt).

A war in Iran, a spike in oil, sticky inflation, delayed rate cuts, strained supply chains, and weakening consumer confidence can form exactly that kind of chain reaction. Any one of those problems might be manageable on its own. Together, they can change the market’s mood in a hurry.  

These geopolitical dips create drama in the short-term, but the downside usually doesn’t last for more than a few months.  

War rarely ends when one side gets everything it wants. It usually ends when the price of continuing becomes too high. That is the most likely path here as well. The Iran war is most likely to end not with a clean victory, but with an ugly, negotiated pause: fewer direct strikes, partial reopening of shipping lanes, and heavy outside pressure from the U.S., Gulf states, and major importers that cannot tolerate a prolonged energy shock.

The key variable is oil flow. As long as the Strait of Hormuz remains constrained and energy infrastructure stays at risk, the world has a strong incentive to force de-escalation.

Here’s the script:

• Oil still tends to jump first and hardest because supply risk is immediate and physical.
• Gold can be more complicated. Instead of rising on safe-haven demand, it may sell off as investors raise cash, lock in gains, or respond to shifting rate expectations.
• Stocks usually fall lower as higher energy costs act like a tax on consumers, businesses, and overall economic growth.

Oil is the transmission mechanism that matters most. If disruption persists, the inflation impact will not stay confined to gasoline. It spreads into freight, chemicals, food, fertilizer, and manufacturing inputs. That is how a geopolitical event becomes a macro event.

Will this create another bear market in stocks? It could, but it does not have to. History suggests geopolitical shocks often produce sharp drawdowns without always becoming lasting bear markets. The difference is duration. A brief war with reopening supply routes is more likely to produce a shock, then recovery.

My best guess is that this time of worries may not be over yet. A further -3% to -10% decline in the S&P 500 would not be surprising. If that happens, it could create a very attractive entry point for cash that is still waiting on the sidelines.
