The US dollar weakened against the Japanese yen, with the yen rising 0.3% to a one-week high of 162.88 per dollar. This movement occurred as market attention shifted to the upcoming US Personal Consumption Expenditures (PCE) Index report, which investors will scrutinize for clues on future interest rate paths. Economists anticipate the index to show a 3.7% annual rise in June, down from 4.1% the previous month. Traders have increased their expectations for the Federal Reserve to keep interest rates unchanged in September, with the probability now at 34.8%.
