Mortgage rates retreated from record lows following a sharp sell off of mortgage-backed securities (MBS) late Thursday. Analysts attributed the increase in MBS yields to high refinancing demand. Friday’s economic data came in close to expectations. July Retail Sales rose 0.4%. The Consumer Price Index (CPI) rose 0.3%, while Core CPI, which excludes volatile food and energy components, rose at a slim 0.9% annual rate. Consumer Sentiment came in at 69.6, slightly above forecast. Next week will be relatively light in terms of new economic data. The Producer Price Index and Industrial Production will be released on Tuesday.
