The yen hovered just below the psychologically important level of 145 per U.S. dollar on Monday, while the dollar weakened after U.S. economic data showed easing inflation and consumer spending. The yen weakened 0.03% to 144.38 per dollar, and against the euro, it hovered at 157.495. The yen briefly passed 145 per dollar on Friday, hitting an eight-month low of 145.07. Japanese authorities have signaled that they may intervene in the currency market if the yen weakens excessively. Investor focus this week will be on the minutes of the U.S. Federal Reserve's June meeting.
