US Inflation Unexpectedly Slows Down Ahead of Tariff Impact

Greg Boutle, Head of US Equity & Derivative Strategy at BNP Paribas, joins to react to CPI and talk about his outlook for equities. He speaks with Bloomberg's Tom Keene and Paul Sweeney.

US inflation cooled broadly in March, indicating some relief for consumers prior to widespread tariffs that risk contributing to price pressures.

The consumer price index, excluding often volatile food and energy costs, increased 0.1% from February, the least in nine months, according to Bureau of Labor Statistics data out Thursday. The overall CPI declined 0.1% from a month earlier, the first decrease in nearly five years.

The inflation slowdown reflected a decline in energy costs, used vehicles, hotel stays and airfares. The cost of motor vehicle insurance — a main source of inflation in recent years — also retreated.

The 10-year Treasury yield were little changed after the figures, while the S&P 500 opened lower and the dollar remained weaker.

The report showed little impact so far from tariffs already in place — in categories like toys and appliances that are more exposed to China — although that may change in coming months as President Donald Trump’s higher levies filter through the economy.

And price declines for services like hotel stays and airfares may be a warning sign that some consumers are cutting back on discretionary spending. Trump seized on the good news, noting in a Truth Social post: ‘Just out: “INFLATION IS DOWN!!!”’

“It is the calm before the inflation storm. We’re going to get some higher inflation out of the tariffs,” said David Kelly, chief global strategist at JP Morgan Asset Management, on Bloomberg Television. “What we’re seeing is a lot of softness in the travel industry, which I think is going to get worse over the course of this year.”

While Trump announced 90-day pause on higher reciprocal tariffs on Wednesday — less than 24 hours after they came into effect — imports from most countries are now subject to 10% duties. The US began collecting tariffs last month on imported steel and aluminum, and levies on China now stand at 125% after retaliation from Beijing earlier this week.

Some of the higher import costs will ultimately be passed on to the consumers, and companies from Target Co. to Volkswagen AG have warned higher prices are in store for Americans.

The uncertainty is keeping Federal Reserve officials in wait-and-see mode as they look for more clarity on the impact the levies will have on inflation — and the economy more broadly.

Even with some tariffs already in place in March, some of the categories more exposed to China posted declines, including toys, appliances and smartphones. The CPI report showed core goods prices dropped 0.1% last month, the first decrease since August.

“The experience of tariffs on washing machines in 2018 suggests that it takes three months for consumer prices to respond to new tariffs, after which pass through is rapid,” Samuel Tombs, chief US economist at Pantheon Macroeconomics, said in a note. He added that the impact should be felt with the May CPI report.

While all eyes have been on the impact tariffs will have on goods prices, one of the key drivers of inflation in recent years has been housing costs — which are the largest category within services. Shelter prices rose at a moderate pace, reflecting the steepest drop in hotel stays in more than three years.

There were still signs of lingering price pressures facing households. Owners’ equivalent rent accelerated to a 0.4% monthly pace and grocery costs increased 0.5%, matching the biggest gain since October 2022. Meat prices accelerated, while the cost of eggs posted a smaller advance than a month earlier.
