Interest rate news

Commentary & News:

Mortgage bond prices are higher mid-morning erasing some of the losses seen yesterday afternoon. This despite strong economic data released at the open.

In news released this morning, retail sales rose 1.4%, much stronger than expectation for an increase of 0.6%. Strong retail sales can be viewed as inflationary. Traders initially sold bonds in the face of the data, however buyers finally emerged and have stabilized rates.

Traders are now waiting for the release of Fed Beige Book data set for 2:00 ET. This report details economic conditions across the US. If the report indicates either strong economic activity or rising inflation, rates may suffer.

When asked if he believes rates will climb above 7 percent, Connelly said, “I think [they will]. The economy is strong enough that the Federal Reserve has decided not to lower interest rates.”
