JPMorgan CEO Dimon Warns Bull Market Is Like a "Small Tsunami," Expressing Concern Over Accumulating Global Risks
Miles Bennett
JPMorgan CEO Jamie Dimon compared the current bull market to a 'little tsunami' — once it starts, it's nearly impossible to stop — while warning that geopolitical 'tectonic plates' are shifting beneath the surface and may take years to hit.
The market keeps climbing — why is Dimon uneasy?
The S&P 500 has gained nearly 80% over five years; the Nasdaq is up over 86% — despite the Ukraine war, Middle East conflict, oil shocks, and U.S.-China tensions.
Speaking at the Council on Foreign Relations, Dimon said the market's resilience surprised him.
This means → his worry is not about an imminent crash. It is that the market's immunity to bad news is itself a risk signal — the longer it shrugs off threats, the more energy builds up.
What does 'tectonic plates' mean?
Dimon described Ukraine, Iran, Russia, oil prices, and U.S.-China relations as 'tectonic plates' in motion.
In plain terms = these risks are like deep fault lines shifting slowly underground — you feel no tremor, but pressure is accumulating and could release in a year, or several years.
He placed himself squarely in the 'more cautious' camp, but left room: these risks "could also be resolved in some way."
So what is holding the market up right now?
AI capital expenditure is running at roughly $700 billion this year and is expected to keep expanding — the single hardest pillar under the rally.
Unemployment sits at 4.3%, GDP growth at about 2%, and the "Big Beautiful Bill" has added some consumer stimulus.
But Dimon noted that the bill's boost has already been offset by oil-price rises triggered by the Middle East conflict. This means → the consumer tailwind is being eaten by geopolitical costs, leaving a net effect near zero.
What is the 'little tsunami' metaphor really saying?
Dimon's words: "We're in a bull market, and it's like a little tsunami — once it happens, it's hard to stop."
In plain terms = a bull market's momentum works like a wave — it does not keep rising because fundamentals are fine; it keeps rising because the motion itself carries force, until it hits a wall.
This reflects Dimon's core conviction: all cycles end. The question is not *whether* this one stops, but *when and what stops it*.
What does this mean for ordinary investors?
Two variables sit at the center of the market right now: whether AI capex can keep delivering returns + when geopolitical 'tectonic plates' transmit their force into the real economy.
The intersection of those two variables is the test point for Dimon's warning — if AI returns disappoint while geopolitical risks materialize, the bull market's 'tsunami' hits its wall.
Put simply = no need to panic today, but recognize this: a market that doesn't fall is not the same as a market with no risk — the risk just hasn't arrived yet.
