Inflation’s Next Shoe May Be Tariffs

Written by Mark Malek | June 09, 2026

Markets may think tariffs are old news, but a new tariff structure is quietly forming just as inflation risk returns.

KEY TAKEAWAYS

  • The market has largely moved on from tariffs, but the tariff structure has not disappeared. It has been rebuilt through other legal channels.

  • The current 10% global surcharge expires July 24th, and new USTR actions appear timed to replace or extend the pressure. That makes the timeline look less like coincidence and more like a relay race.

  • Existing tariffs already include Chinese goods, metals, and a coming 100% tariff on patented pharmaceutical imports. That stack exists before any new Section 301 action.

  • Inflation risk is being underestimated because tariffs have not fully hit earnings or consumers yet. Record corporate margins suggest the bill may still be working its way through the system.

  • Energy risk makes the tariff problem more dangerous. A Strait of Hormuz escalation layered on top of new tariffs could trap the Fed and squeeze consumers.

MY HOT TAKES

  • Wall Street is treating tariffs like a solved problem because the headlines moved on. That is exactly when the risk becomes most dangerous.

  • The Supreme Court ruling changed the legal route, not the policy destination. The tariff vehicle was replaced almost immediately.

  • A 15% to 30% tariff structure on Europe would not be abstract. It would hit pharma, luxury goods, autos, industrials, and investor portfolios hiding inside international allocations.

  • Corporate margins may be telling a comforting story for now, but they may also be masking delayed tariff costs. Somebody eventually pays.

  • The real second-half risk is not just tariffs or oil or the Fed in isolation. It is the combination arriving at the same time.

  • You can quote me: “The bill has a funny habit of arriving right when everyone has stopped watching the mailbox.”

 

Bills coming due. My long time followers know about my now-famous Old Wall Street Sayings notebook–tattered, edges soft from years of folding it into briefcase pockets (lol, I used to use a briefcase, actually still in my garage 🤣)–and one page I more recently keep coming back to that reads: "The market forgets before the bill arrives." My friends, that is where we are with tariffs.

 

Somewhere between the bond market's preoccupation with a 10-year yield that just punched back through 4.50%, the Fed's paralysis, and the AI earnings parade, the pending mega-IPO superstorm, and the on-again-off-again Strait of Hormuz closure, the financial press decided the tariff war was yesterday's story. The Supreme Court ruled. The president pivoted. The headlines moved on. One of my friends called me last week and told me the trade uncertainty was "largely resolved." I wrote that down too.

 

What he missed, and what I'm going to walk you through today, is that the tariff architecture hasn't been dismantled. It has been rebuilt–quietly, methodically, and using legal authorities that have no rate caps, no expiration dates, and no Supreme Court precedent blocking them. The 10% global surcharge sitting on virtually every import into this country expires July 24th. The administration knows that. Which is why, on June 2nd, the USTR quietly proposed a new round of tariffs covering sixty trading partners, including the EU, Canada, Mexico, and the UK, framed around forced labor enforcement ( 👀 that’s not a typo). The comment period closes July 6th. One day after the hearing. Two and a half weeks before the current tariff clock runs out. That is not a coincidence. That is a relay race.

 

Meanwhile, the inflation picture looks exactly like what you'd expect when the market has decided the hard part is over. Headline CPI is running at 3.8% year-over-year. PCE is at 3.77%. Corporate margins just hit their highest level in fifteen years–which tells you the tariff costs haven't landed on earnings yet. They've been absorbed, passed through selectively, or simply ignored by a market too busy celebrating the AI earnings parade to notice that a new permanent tariff architecture is being quietly assembled in the background. Tomorrow morning we get the May CPI print. I'll be watching it closely. Not because one number changes everything. Because the most dangerous moment in markets is when everyone is certain the problem went away.

Let me tell you what is actually on the books right now, because the stack of tariffs currently sitting on imports into this country would surprise most people who think the story ended in February.

 

The Section 301 tariffs on Chinese goods–the ones from the first Trump term–never went away. They are still there, still accumulating, still embedded in the cost of everything from electronics to industrial components. On top of those sit the Section 232 metals tariffs, which were just overhauled in April and now cover steel, aluminum, and copper in restructured form. And then, effective July 31st for large companies, comes the one that has received almost no mainstream coverage: a 100% tariff on patented pharmaceutical imports. Also, not a typo. 100%! The default rate on the branded drugs that tens of millions of Americans depend on, sourced from manufacturing operations in Europe, Japan, and elsewhere. Generics are excluded for now, but the administration has mandated a formal review of that exclusion within a year. The clock on that one is also ticking.

 

This is the tariff stack that exists today, before a single new Section 301 action takes effect.

Now let's talk about the Supreme Court ruling, because the mainstream narrative got it badly wrong. Yes, the Court struck down the IEEPA tariff regime in February with a 6-3 decision that ruled the president had exceeded his constitutional authority. That part is accurate. What got buried is what happened next. Within hours of the ruling, the administration had a new 10% global surcharge in place under a different legal authority entirely. And within weeks, it had launched investigations under Section 301, a statute with no rate cap and no expiration date, covering sixty trading partners simultaneously. The legal vehicle that SCOTUS blocked has already been replaced! The target hasn't changed.

 

The EU situation deserves its own moment of attention. The administration is pushing for a minimum tariff of 15% to 20% on European goods even if a trade deal is reached, and has threatened 30% or higher if the July 4th deadline passes without agreement. Many retail investors have loaded up European equities in the past year and many more have indirect European exposure, and I fear that they have little or no clue about it. It's sitting inside the international allocation of virtually every balanced fund on the market, in the form of European pharma, luxury goods, autos, and industrial equipment. A 20% to 30% tariff on that supply chain is not an abstraction. It is a cost that lands somewhere, whether on corporate margins, on consumer prices, or both.

 

And here is where the energy picture makes all of this worse. The Strait of Hormuz situation has not resolved. Brent crude is hovering just below the threshold that analysts describe as the level where energy costs stop being a market variable and start being an inflation shock. We are one escalation away from that line. If you layer an energy price spike on top of a new permanent tariff regime landing in late July, you get a Fed that cannot cut, a consumer that is already stretched, and a bond market that has to reprice everything it thought it knew about the second half of 2026.

 

The reason I decided to write about this today was to remind you that inflation, which is the most powerful source of potential market and economic risk right now, is still very much under the control of not just energy but also tariffs that, while they have all but disappeared from the mainstream media narrative, they are still very much present in your monthly budget, and they are likely going to increase the wrong side of it as summer waxes and wanes.

 

That is not a prediction. It is a description of the risk that is already assembled and waiting.

The market has decided tariffs are solved, energy is contained, and margins will keep climbing. That may be right. But the bill has a funny habit of arriving right when everyone has stopped watching the mailbox.
