One year ago this week, I was watching tariff policy change in real time and thinking the same thing every CFO and controller I know was thinking: there’s no way to model this.
April 2, 2025. Trump stands in the Rose Garden and calls it Liberation Day. Sweeping tariffs on virtually every trading partner. China hits 145% for a stretch. Then rates come down. Then they go back up. Then the Supreme Court rules the whole legal framework unconstitutional in February 2026 — and the administration reimposed roughly equivalent rates under a different statute the same week.
By the time the dust settled, tariff policy had changed more than 50 times in 12 months. Fifty. That’s not policy. That’s weather.
The Lesson Isn’t About Tariffs
Here’s what I keep coming back to when I look at the data from 2025: three in four goods-producing companies raised prices. Three in four still saw their margins shrink. Raising prices wasn’t enough.
The companies that came through the year intact weren’t the ones with the best tariff forecasts — because you can’t forecast something that changes 50 times. They were the ones built to handle not knowing. The ones with an umbrella in the car regardless of what the weather app said.
The data makes this concrete. By year-end, only 1 in 5 companies with heavy international supply chain exposure reported a good or great year. Compare that to nearly 2 in 3 companies with primarily domestic sourcing. Same tariff environment. Same policy chaos. The difference was visibility — specifically, how much visibility those companies had into their exposure before any of it started.
Three Things That Separated the Winners
I’ve been working closely with finance teams through a lot of volatility over the past few years, and the pattern that showed up in 2025 is one I’ve seen before. It comes down to three things.
First: data infrastructure that reflects how you actually buy. More than half of CFOs cited limited data access as their primary blocker when tariffs hit — not strategy, not headcount, not capital. Data. They literally couldn’t answer “what does a 25% tariff on goods from this country do to our margin?” in a timeframe that was useful. If that’s where your team is, that’s not a tariff problem. That’s a data problem, and it’ll show up the next time there’s a shock, whatever form that takes.
Second: scenario planning as a standing capability, not a one-time exercise. The companies that absorbed 2025 well weren’t necessarily the ones who had tariffs in their scenario set. They were the ones whose planning muscle was developed enough to rebuild assumptions quickly. There’s a meaningful difference between doing a scenario analysis when a crisis hits and having pre-built, modular models you can re-parameterize on short notice. You don’t need a massive, board-ready model for this. Sometimes a smaller, more directional model — something you can tweak to get a sense of the magnitude before deciding whether to go deeper — is exactly what you need to start answering questions fast.
Third: the CFO role has permanently shifted. What 2025 showed is that reporting what happened is becoming table stakes. The value is in modeling what might happen next and how fast you can help the organization pivot. The finance functions that will have a seat at the table going forward are the ones built for that role — with the data, the tools, and the planning cadence to support it.
The Home Depot Story
The example that sticks with me from 2025 is actually Home Depot. Years before Liberation Day — not in response to it — they had made a deliberate strategic decision to cap any single non-U.S. country at no more than 10% of their total purchases. That’s a sourcing diversification policy. When tariffs hit, they had options. They could shift volume. They could renegotiate. They had runway.
Companies that had spent years consolidating sourcing into a single low-cost region — optimized for efficiency, lowest unit cost — had no play. Fully exposed, nowhere to go. That’s not a tariff story. That’s a supply chain design story. And the finance function either has visibility into that design or it doesn’t.
It’s Not Over
One more thing worth saying: the tariff environment isn’t resolved. Section 122 tariffs run through at least July 2026. The USTR has already opened new Section 301 investigations. Policy volatility as a baseline condition is probably here to stay. The question isn’t whether the next shock is coming — it’s whether your FP&A infrastructure is ready for it.
Key Takeaways
- Tariff policy changed 50+ times in 12 months. The lesson isn’t about tariffs — it’s about what your finance function looks like when the rules change that fast.
- 3 in 4 goods companies raised prices in 2025. 3 in 4 still saw margins shrink. Margin protection came from supply chain design and data work done before the crisis.
- The #1 blocker CFOs cited was limited data access — not strategy, not capital. If you can’t model a major cost variable quickly, that’s the gap to close first.
- Scenario planning is a muscle, not a project. Companies with pre-built flexible models absorbed Liberation Day. Everyone else spent 2025 in reaction mode.
- The tariff environment isn’t resolved. Section 122 tariffs run through July 2026 minimum. Build the infrastructure now, before the next shock arrives.
