The skunk in the markets

Jamie Dimon’s economic outlook reeks: After flagging “cockroaches” in the system last year, he’s now warning about a skunk.

In his annual letter to shareholders, Dimon laid out a growing list of risks facing the US economy, comparing them to “tectonic plates, always moving and periodically causing earthquakes and volcanoes when they crash into each other.” Among his biggest concerns:

• Geopolitical uncertainty: Conflicts in Ukraine and Iran are fueling volatility in energy markets, with knock-on effects across critical commodities like helium and fertilizer, further disrupting global supply chains.
• Rising debt levels: Global deficits are at “extreme” highs. “The right way would be to deal with it now before it becomes a problem,” he warned. “The wrong way would be to let it become a crisis, which, in my opinion, is probably the likely outcome.”
• Private credit: The $1.8 trillion private credit market is small relative to the $13 trillion bond market and thus does not pose a systemic risk, but weakening standards and poor transparency could drive higher-than-expected losses when the credit cycle turns, especially if interest rates rise.

Not everything stinks

But enough with the doom and gloom. Dimon also highlighted some meaningful tailwinds:

• US resilience: The economy is far less energy-dependent today, with energy use per unit of GDP down to roughly 40% of the usage seen 45 years ago.
• Fiscal boost: The “big beautiful bill” could inject roughly $300 billion (1% of GDP) into the economy.
• Liquidity support: The Fed is purchasing about $40 billion in securities each month. While that’s set to taper to $20 to $25 billion this month, it still helps prevent a liquidity squeeze in the system.
• Deregulation: Looser regulations are freeing up capital and boosting confidence, with spillover effects across sectors from banking to energy to housing.
• AI spending boom: Hyperscaler capex surged from $450 billion in 2025 to $725 billion in 2026—likely inflationary in the short-term, but a long-term driver of productivity gains.

A smell-test for markets

Despite the hints of optimism, the big picture still looks uncertain even to Jamie Dimon’s well-trained nose. But the real wildcard he’s watching right now is inflation.

“The skunk at the party—and it could happen in 2026—would be inflation slowly going up, as opposed to slowly going down,” Dimon noted. “This alone could cause interest rates to rise and asset prices to drop. Interest rates are like gravity to almost all asset prices. And falling asset prices at one point can change sentiment rapidly and cause a flight to cash.”

From cockroaches to skunks, it probably won’t be long before a few more critters follow—Dimon’s a notoriously pessimistic investor, and not all of his warnings over the years have been accurate. Let’s just hope the next animal he chooses for a metaphor is a little easier to stomach.—SY
