Consumer prices posted the biggest increase in June in five months and are likely to keep the Federal Reserve from cutting interest rates soon, but there only scattered signs of tariff-related inflation.

The U.S. is expected on Tuesday to report that rising costs for imported goods lifted overall consumer prices in June, kicking off what might be several months at least of such increases and giving Federal Reserve officials highly awaited data on whether the Trump administration's tariffs are boosting inflation.

“While any tariff induced boost to inflation is likely to be short-lived, with higher tariffs being announced it would be wise for the Fed to remain on the sidelines for a few more months at least,” said Seema Shah, chief global strategist at Principal Asset Management.

Inflation rose last month to its highest level in four months as the cost of gas, food, and groceries rose, reversing several months of cooling price pressures.

Minutes from the Fed’s June policy meeting tease at a looming split over whether and when officials will resume rate cuts.

The emerging divide among Federal Reserve officials over the outlook for interest rates is being driven largely by differing expectations for how tariffs might affect inflation, a record of policymakers’ most recent meeting showed.
