Mortgage rates inched lower Thursday in quiet trading ahead of next week’s key Fed meeting. In economic news, weekly Jobless Claims declined sharply to 292,000, but the figures were of little comparative value as the totals lacked data from two states that were updating their computer systems. August Import Prices were unchanged from July, which was below forecast. Stocks were mixed. Results from today’s 30-year Treasury auction will be released at 1:00 PM.
