Critics of President Trump's tariff policies have been waiting for the import taxes to raise the inflation rate. That effect may be beginning.

A fresh report on Tuesday marked two consecutive months of rising inflation. Consumer prices rose 2.7% in June compared to a year ago, marking a notable surge of price increases as President Donald Trump's tariff policy took hold and some retailers warned they may pass some of the tax burden onto shoppers.

New data showing price increases last month could foreshadow even higher costs if the president imposes steep tariffs on Aug. 1.
