Tariffs and the Second Inflation Scare

Liberation Day

On April 2 2025 in the Rose Garden of the White House President Trump announced what he called Liberation Day a sweeping tariff package covering nearly all of the United States' trading partners. rate It is a tax on imported goods paid at the border by the importing company and through 2025 the average rate the United States actually collected had remained around 2.4 percent for decades. The new package set a 10 percent minimum for virtually all imports with much higher country-specific rates applied to China the European Union Japan and dozens of others

Scale is the point.Based on actual customs revenue the average effective tariff rate for 2025 was 7.7 percent more than triple the previous year and the highest level since 1947. Whatever one thinks of the policy it was the biggest change in American trade policy in the postwar era executed in months

One Week of Freefall

Markets didn't take it easy. In the days after April 2 the S&P 500 fell about 12 percent the kind of drop that typically occurs in a recession as investors tried to price in a worst-case scenario in which retaliation escalated into a global trade war. Then on April 9 the administration announced a 90-day pause on most country-specific rates to allow for negotiations and the S&P500 rose 9.5 percent in a single session one of the largest one-day gains since World War II

That whiplash taught traders a pattern they would lean on throughout the year selling the ad and buying the pause. The tariffs that remained were mostly the basis of the 10 percent plus high rates levied on China while the Rose Garden cartel's more extreme figures never fully took effect. Courts also spent the year arguing whether the emergency powers used to impose them were legal adding another layer of uncertainty that markets learned to ignore

The Inflation Everyone Watched For

The second inflation scare is why this article is part of a series on markets rather than politics. The first scare covered in our 2021 and 2022 entries came from stimulus and supply chains and peaked at over 9 percent. The tariff scare took a different form. Headline CPI the consumer price index stood at about 2.6 percent in the year after Liberation Day which at first glance is unremarkable.The tariff signature appeared in basic goods Prices for physical products excluding food and energy had been falling in 2024 and started rising after April 2025 peaking at around 1.5 percent annual growth in August 2025

Fed Chair Powell estimated the tariff contribution at between half a percentage point and three-quarters of a point of additional inflation which was largely the reason inflation ran above the Fed's 2 percent target instead of meeting it. That estimate was important because it framed the tariff effect as a one-time change in the price level rather than a persistent inflationary spiral which is why the Fed held rates in place instead of raising them

A Worked Example: Turning a Tariff Rate Into a Price Level

Powell's half a point to three-quarters of a point sounds like the result of a large model. This is a rough enough estimate that you can check it yourself and doing so is the quickest way to understand why tripling tariffs produced such a modest inflation figure

Step one the size of the tax increase. The average effective rate went from 2.4 percent to 7.7 percent. The increase is 5.3 percentage points applied to the value of imported goods

Step two what part of the economy it touches. This is the step everyone skips. The United States imports a lot in absolute terms and comparatively little as a proportion of what it consumes. Total imports of goods and services are around 14 percent of GDP and goods alone are closer to 11 percent. The other 86 to 89 percent of what Americans buy which is overwhelmingly services housing and domestically produced goods is not directly affected by a border tax

Step three multiply. If every dollar of tariff were passed through directly to prices the direct effect on the overall price level would be 5.3 percent times the share of imports

This is a range of about 0.58 to 0.74 percentage points which falls almost exactly on the estimate of half a point to three-quarters of a point given by the chairman of the Federal Reserve. Two lines of arithmetic reproduced the official number

The exercise is worth more than the answer for what it reveals about the shape of the effect. Note that this is a level change once not an inflation rate. Prices rise 0.7 percent and then stop rising because the tariff will not increase again next year. Twelve months after the full transfer the tariff does not contribute at all to the year-over-year inflation rate

That distinction is the only reason the Federal Reserve held its rates in place instead of raising them. Central banks respond to persistent inflation that is a rate that continues to rise. A change in the price level is painful for households and has already happened. Entering into it would have suppressed demand to fight a price increase that had already finished occurring

These figures are rounded and assume a full step which as shown in the next section did not occur in its entirety. Both simplifications tend to exaggerate the effect which is presumably why the real number is at the lower end of a range that arithmetic sets at the top

Who Actually Paid

The textbook question about any tariff is incidence that is who ultimately bears the cost between foreign exporters importing companies and consumers. The evidence from 2025 suggests that the cost was divided. Some exporters reduced prices to maintain their market share some importers consumed the margin and the rest moved to shelf prices which is exactly what the commodity data shows. The federal government for its part collected record customs revenues whichwhich supporters considered a victory and critics called the tax increase by another name

Case Study: The Washing Machines That Made Dryers More Expensive

The 2025 package is too recent and too complicated for clear measurement. There is an earlier U.S. tariff that economists were able to study almost like a lab experiment and what they found is the most useful thing you can know about the incidence

In January 2018 the United States imposed safeguard tariffs on large imported residential washing machines. The market was concentrated the product was easy to identify and prices were tracked in detail making it an unusually measurable policy

Washing machine prices rose about 12 percent. That was expected. The finding that made the study famous is that dryer prices rose by a similar amount over the same period and the dryers were not subject to any tariffs

The explanation is that washers and dryers are sold in pairs and manufacturers raised the price of the duty-free add-on because they could. Domestic producers who did not face any tariffs also raised their prices toward the new import price because the tariff had eliminated the cheaper competitor that had been holding them back. Both effects are invisible in any calculation that focuses solely on taxed goods

Researchers estimate the total cost to consumers at about $1.5 billion a year compared to about 1,800 jobs created in the domestic manufacturing sector which equates to a cost per job of about $800,000 a year

Two lessons will carry over directly to the year 2025. First the transfer was substantial and reached beyond the taxed product to domestic complements and substitutes meaning that the example worked above almost certainly underestimates the cost to the consumer when looking only at the share of imports. Second the policy achieved its stated objective. Jobs were created. They were simply extraordinarily expensive and the bill was footed by the people who bought laundry appliances and not those who voted for them

What It Did Not Do

It's worth recording what didn't happen because the comments in the spring of 2025 predicted much worse. There was no recession in 2025. Unemployment did not skyrocket. The dollar did not collapse. Supply chains were diverted rather than broken and import patterns shifted to countries with lower rates. The economy absorbed the biggest trade shock in generations with a rise in the price level and a lot of noise at corporate margins which is really surprising and worth it.worth remembering the next time a policy change is described as a guaranteed catastrophe

What it did do was leave a higher cost floor under the economy just as 2026 produced a true oil shock and that combination tariff costs plus war-driven energy prices is what pushed inflation back above 4 percent and locked in the new Fed chair. Policies interact. The tariff story didn't end in 2025 it just passed the baton to the next shock

Where the Reassuring Reading Breaks

I've written most of this as a story about a shock that turned out to be less than feared. That reading is defensible and also convenient so here's the case against it

The announced policy was never tested. The April 9 pause eliminated most country-specific tariffs in a week. What the economy absorbed was a 10 percent base plus elevated rates from China not the Rose Garden sign. Concluding that the economy shrugged off the biggest trade shock in generations is not entirely correct because the larger version was withdrawn before it took effect. We tried the small version and passed

One year is too short for a change in the price level. Long-term supply contracts existing inventory and annual price cycles mean that a tariff imposed in April 2025 was still working in supply chains well into 2026. Stating that the effect of inflation is limited to twelve months of data measures the part that moved the fastest

Changing routes may involve relabeling. Shifting import patterns toward countries with lower rates sounds like a healthy adaptation. Some of it is. Some of it is transshipment where goods take an extra leg through a third country to change their documentation which raises real costs produces no domestic benefit and shows up in statistics as successful diversification

The washing machine finding suggests that the measured effect is too low. If tariffs raise the prices of untaxed complements and allow domestic producers to raise prices under the umbrella then by attributing only taxed goods to the policy a significant part of the cost is lost. Reading the CPI for basic goods captures the direct channel well and the umbrella effect poorly

No recession is not the same as no cost. The corporate margin takeover is a real transfer it simply lands in places that do not have their own monthly data release. The absence of a catastrophe in the headlines is weak evidence of the absence of damage

My honest read is that 2025 was actually less bad than predicted and that the reason is more pause than resilience which is a much less comforting conclusion

How I Actually Read a Tariff Headline

Trade policy generates more noise per unit of information than almost any other topic so I have a short filter

The first question is always what is the effective rate not what is the advertised rate. Advertised rates are negotiating positions subject to exemptions exclusions quotas pauses and litigation. The effective rate calculated from the actual customs revenue divided by the actual value of imports is the only number that has already survived all that. In 2025 the gap between the two was enormous and the entire history of the market lived in it

Second I run the two-line calculation in the example above before reading anyone's analysis. The rate change times the import share gives a ceiling to the direct price effect and it takes thirty seconds. Any comment that predicts an effect well above that ceiling is an argument about second-round effects and should say so explicitly

Third I look at commodities rather than the overall CPI because that's where a tariff signature would show up and the core is dominated by things a tariff doesn't touch

Fourth I try to separate the level from the rate. Most public arguments about tariffs and inflation are two people talking over each other one describing a permanent increase in prices and the other describing a temporary increase in the inflation rate both correct and about different things

My own opinion and it is just an opinion is that the lasting cost of 2025 was not rising prices but uncertainty and that uncertainty is not reflected in the CPI at all. It shows up years later in investments that never happened

The Bottom Line

2025 reshaped American trade policy at a speed no one thought possible tripling the effective tariff rate to its highest level in nearly eighty years. The market crash it caused lasted a week the inflation it caused was real but limited and the uncertainty it caused never completely disappeared

Arithmetic explains the modest inflation figure better than any narrative. A 5.3-point increase in the effective rate applied to imports worth 11 to 14 percent of the economy gives between 0.58 and 0.74 percentage points of the price level. This is a one-time step and not an interest rate which is precisely why the Federal Reserve held its rate instead of raising it

The 2018 washing machine tariff is a reminder that the measured cost is a floor. Prices rose about 12 percent on washing machines and a similar amount on dryers that were never taxed at a cost of about $1.5 billion a year and something close to $800,000 per job created. The honest scorecard is a mixed bag: no disasters no free lunches and a permanently higher cost of the imported goods it still fueled.inflation figures a year later.For anyone learning how markets digest policies Liberation Day is the best case study of the decade
