Internet reported that the U.S. dollar fell slightly but remained within a narrow trading range as investors awaited Tuesday's U.S. consumer price index inflation data. The dollar fell last week, mainly due to weak jobs data and Milan's temporary appointment as a Fed governor, raising the possibility of a rate cut. Tuesday's data may show the early impact of U.S. trade tariffs on inflation. Pepperstone's Chris Weston said the market is concerned about the extent to which core commodity inflation is affected by tariffs.
