Mortgage rates were little changed Monday as today’s economic data came in close to expectations. January Core PCE price index, the Fed’s preferred measure of inflation, rose 0.1%, matching forecast, and was a tame 1.1% higher than one year ago. The Institute for Supply Management manufacturing index increased to 53.2, a bit higher than expected. Readings above 50.0 indicate expansion in the manufacturing sector. No other key data will be released today.
