The Slow Climb

You don't remember when it changed.

There wasn't a day it happened. No single trip where you looked at the receipt and thought: this is different now. It was slower than that. It was the kind of change that folds itself into routine until routine is all you feel.

You used to buy the same laundry detergent every two weeks. Same brand, same size. You didn't check the price because the price never moved enough to notice. Then sometime — was it May? June? — you noticed the number was different. Not dramatically. Just enough to register for one second before you put it in the cart anyway.

Then the rice was a little more. Then the paper towels. Then the off-brand shampoo your kids don't complain about.

None of it felt like a crisis. None of it made the evening news. Nobody protested in the parking lot of the grocery store. You just — adjusted. You stopped comparing. You stopped tracking. You adapted your baseline, one quiet Tuesday at a time.

That's how it works. Not with a bang. With a receipt that costs eleven dollars more than it did last spring and no single line item you can point to.

The Federal Reserve just named the mechanism. And the name is precise: the slow climb.

On March 5, 2026, the Fed's Board of Governors published a FEDS Note by economists Hacıoğlu-Hoke, Malladi, and Feler^[1] using item-level retail data from 200,000 U.S. households — the Numerator consumer panel — combined with country-of-origin product tracking. The finding was definitive: tariffs imposed in 2025 did not produce a one-time price shock. They climbed gradually, almost invisibly, into consumer prices beginning around April 2025 and accelerating through the fall.

The methodology matters. The researchers used a Fisher Price Index — the same approach underlying the Fed's preferred PCE inflation measure — and validated their retail panel against the Bureau of Economic Analysis PCE deflator for food, achieving a 0.96 correlation.^[3] This isn't a think-tank estimate. It's the Federal Reserve measuring its own economy with its own tools and finding a tax it didn't impose working exactly as economic theory predicted.

The statutory effective tariff rate on Chinese goods reached approximately 30%. The realized effective rate, accounting for exclusions and reclassifications, landed at roughly 26%. The difference didn't save consumers — it just slowed the climb by a few weeks.

The data also reveals what didn't move. Canadian goods showed muted price changes, likely reflecting the different tariff structure under USMCA. U.S.-produced goods stayed below 2% annual increases. The climbing was concentrated precisely where the tariffs were concentrated — on imported consumer products, especially from China.

The "others" category is particularly instructive. Countries not named China or Canada — the trade diversion destinations — saw goods prices climb 5%+ year-over-year by December. Tariff evasion through rerouting didn't eliminate the cost. It dispersed it across more supply chains. The slow climb has no single origin anymore. It arrives from everywhere.

This is not a new finding. It is the confirmation of a pattern economists have documented since the first round of tariffs in 2018.

Cavallo et al. (2025) estimated tariff pass-through rates using earlier data and found substantially similar results: consumers absorbed the majority of tariff costs, with minimal evidence that foreign exporters lowered prices to compensate.^[4] Dvorkin et al. at the St. Louis Fed reached the same structural conclusion — tariffs function as a consumption tax, not a production incentive.^[5]

What's new is the granularity and the timeline. The FEDS Note tracks the 2025 tariff wave with item-level precision across 200,000 households. It shows that cumulative inflation from 2018 through 2025 reached 28–38% across all product origin categories. The tariff contribution is layered on top of pandemic-era inflation, supply chain recovery markups, and monetary tightening. The slow climb didn't start the fire. It added fuel so gradually that most people thought the fire was out.

For real estate, the mechanism matters directly. Households adjusting to higher consumer costs have less margin for housing. Mortgage applications don't collapse because rates spike — they erode because the grocery bill, the gas bill, the household goods bill each took a quiet step up. The slow climb reaches the housing market the same way it reaches the shopping cart: without announcement.

The most dangerous inflation isn't the kind that makes headlines. It's the kind that becomes normal. When the Federal Reserve itself documents how tariff costs passed through to your receipt — slowly, steadily, with no single moment you could point to — the mechanism is no longer debatable. It's measured.

The slow climb is also a slow squeeze. And the squeeze doesn't end when you stop noticing it.
