March’s US Consumer Price Index (CPI) data showed a surprising decline, offering the Federal Reserve some relief as it navigates the delicate balance between inflation and economic growth.
The headline CPI dropped by 0.1% last month, the largest monthly drop since May 2020, primarily driven by a sharp 6.3% decrease in gasoline prices.
The drop in prices gave Fed officials a momentary reprieve as they continue to evaluate their monetary policy stance amid persistent economic uncertainties.
The CPI data was unexpectedly soft in March, which gives the FOMC “a bit of breathing room,” according to analysts at Wells Fargo.
Even when excluding volatile food and energy prices, core CPI rose a modest 0.1%, marking the smallest increase since January 2021.
“Big declines in some of the more volatile travel-related components contributed to the slowdown,” Wells Fargo noted, highlighting deflation in airfares, lodging away from home, and used autos.
Assessing impact of tariff increases
This easing in inflation is somewhat at odds with ongoing tariff-related concerns. Wells Fargo cautioned that the decline in CPI may not reflect the full impact of recent tariff hikes. "Our current working assumption is that the year-over-year rate of core CPI will be back to nearly 4% at the end of the year.”
Analysts are predicting a potential rise in inflation once the full effect of tariffs, including a 125% tariff on Chinese imports, take hold. Chris Zaccarelli, chief investment officer at Northlight Asset Management, echoed this concern. "What a difference 24 hours makes – not only is the immediate tariff threat pushed off for three months, but imminent inflation threat has been avoided for now."
Zaccarelli emphasized that while the March CPI data provide a temporary respite, the situation remains fluid. "It’s much too soon to blow the all-clear – both on tariffs or on inflation," he cautioned, noting that the full impact of tariffs has yet to be fully realized.
Despite the easing in headline inflation, concerns about the long-term inflation trajectory remain. Wells Fargo pointed out that although core CPI has fallen to a four-year low of 2.8% year-over-year, the rise in tariffs could push inflation higher in the coming months. "The average effective tariff rate is set to jump to 27% this year from just over 2% last year, and we continue to expect a meaningful pickup in inflation," the bank’s analysts stated.
Narrow window for rate hikes
For now, the Fed appears to have a narrow window to remain cautious on rate hikes, with the March CPI figures offering some relief. However, as Zaccarelli pointed out, the real test will come in the coming months as the full effects of tariffs and global economic shifts play out.
"We will be keeping a close eye on PPI tomorrow in order to determine whether or not future inflation is already in the pipeline," he said.
This uncertainty around inflation adds further complexity to the Fed's decision-making. Wells Fargo projects that the central bank will likely cut the federal funds rate by 125 basis points by year-end to support the labor market if economic growth slows further.
