Mortgage rates were little changed Friday in quiet trading. The August Consumer Price Index (CPI) increased 0.3%, matching forecast. The more closely watched “Core” CPI, which excludes food and energy components, rose at a lower than expected 0.9% annual rate, easing inflationary concerns in the near term. Consumer Sentiment fell to 66.6 this month, the lowest level since August 2009. A reading of 70.0 had been expected. Next week’s big event will be Tuesday’s FOMC meeting of the Fed. While no rate changes are expected, investors will be watching closely for clues on the future direction of monetary policy. No other data will be released today.
