The market is still underpricing a tariff-driven inflation second wave

Investors are still treating tariffs like a temporary headline risk when the more important story is the interaction between sticky price pressure, higher yields, and a weakening consumer. That mix matters less for the next CPI decimal than for who leads the market in a higher-for-longer regime — and recent retail and pricing data suggest that repricing is not finished.

The market is still underpricing a tariff-driven inflation second wave

The market is still too relaxed about tariff inflation. Not because every tariff dollar will show up neatly in the next CPI print, but because the second-order effects are already lining up: input prices are hot, yields are sensitive to renewed inflation fears, and the consumer is showing strain just as companies start talking more openly about cost pressure. That is the setup for a higher-for-longer regime, and markets still look positioned as if tariffs are a one-off nuisance rather than a force that can reshape sector leadership. Monday’s ISM prices data matters for exactly that reason: it is a regime signal, not just a macro trivia point.

The cleanest evidence is not in a single inflation release. It is in the way cost pressure is moving through the system before it fully hits the broad price indexes. The ISM manufacturing prices paid index surged to 84.6 in early May, the highest since April 2022. That is not the reading of an economy shrugging off a temporary trade shock. It is the kind of forward-looking pricing signal that says companies are absorbing more pressure now and will either pass it through later or accept weaker margins into a softer consumer backdrop. Neither outcome is benign for the market’s current higher-for-longer complacency.

That is why the recent retail and staples prints matter more than the next hot take on whether tariffs add a few tenths to CPI. Walmart and Costco are usually treated as safe havens when consumers trade down, but their latest results also show the mechanics of inflation stress. Walmart grew revenue 7.3% to $177.8 billion in its latest quarter, yet operating income rose only 5.0%, with management citing a 250 bps hit from higher fuel costs in distribution and fulfillment. Costco posted net sales up 11.6% to $69.15 billion, but gross margin still slipped 21 bps to 11.04%. That is the point investors are underestimating: even the winners are not escaping the squeeze cleanly.

The market has partly recognized that staples and discounters are relative shelters, but it has not fully priced what that shelter really looks like. These are not cheap, bombed-out defensives waiting to be rediscovered. WMT trades at 41.07x earnings and COST at 49.81x, both rich multiples for businesses with net margins of just 3.2% and 3.0%, respectively. Investors are paying up for resilience, but resilience is not the same as immunity. In a tariff-driven second wave, these companies can still outperform more cyclical parts of the market on a relative basis while facing margin pressure that limits how much absolute upside those valuations deserve.

  • WMT: 41.07x P/E, 3.2% net margin, +3.5% YTD
  • COST: 49.81x P/E, 3.0% net margin, +12.1% YTD
  • PG: 21.16x P/E, 19.2% net margin, +2.1% YTD
  • KO: 25.15x P/E, 27.8% net margin, +15.7% YTD
  • TLT: -1.5% YTD

That comparison is where the higher-for-longer argument gets sharper. If tariff pressure keeps inflation expectations sticky, the market should reward pricing power and punish duration. Procter & Gamble and Coca-Cola look better positioned than the low-margin retail defensives because they have much more room to protect profitability if costs rise again. PG’s net margin is 19.2%; KO’s is 27.8%. By contrast, Walmart and Costco live on razor-thin margins, which makes them operationally strong but financially more exposed to cost pass-through friction. And if yields stay elevated because inflation fears revive, TLT remains vulnerable. The market is still acting as if tariff inflation is mostly a growth scare with some headline noise attached. It looks more like a regime where quality defensives and long duration stop moving together.

Yes, the pushback is real. Bulls can argue that tariffs may hit margins without creating a full second inflation wave, and there is some evidence businesses have absorbed costs before rather than passing them straight into final prices. They can also argue the tariff impulse may peak soon. But that misses the market point. Investors do not need a dramatic CPI breakout for this thesis to matter; they only need a world where inflation stays sticky enough to keep yields elevated, consumers cautious, and sector leadership narrow. May retail sales disappointment and the record-low consumer sentiment narrative already fit that pattern.

That also explains why the financials are not an easy escape hatch. JPMorgan at 14.16x earnings looks far cheaper than staples, but cheapness alone is not the signal if the macro mix is slower growth plus stubborn inflation pressure. Banks can benefit from higher rates up to a point, yet a more strained consumer and a market repricing around inflation risk is not the clean cyclical backdrop equity bulls want. JPM is already down 9.1% YTD, while KO is up 15.7% and COST is up 12.1%. The leadership message is already there. The market has started to rotate, but not decisively enough to say the inflation second-wave risk is fully reflected.

The mistake is thinking this debate hinges on whether the next CPI print is hot enough to trend on financial television. The more important question is whether tariffs are arriving into an economy where price pressure, yields, and consumer fatigue can reinforce one another. Right now, the answer looks closer to yes than the market wants to admit.

Our verdict is bearish on the broad market’s pricing of this theme. We would watch Monday’s ISM prices print, consumer-facing commentary from large retailers and staples companies, and whether long-duration Treasurys can stabilize in the face of renewed inflation chatter. What would change our mind? A clear cooling in forward pricing signals and evidence that companies are protecting margins without further weakening demand. Until then, the safer assumption is that higher-for-longer is still being underpriced.
