Most interest rates were down again during the week ended August 17 and 18, but the changes were not nearly as aggressive as immediately after the Federal Reserve Board's decision to pause in its long term pattern of quarter-point rate increases.
This was the fourth week in a row that rates have dropped and the long term fixed rate products are down at least 20 basis points over that period. Frank Nothaft, Freddie Mac vice president and chief economist commented "This week's news that July housing starts fell 2.5 percent added conviction to Fed Fund futures traders who are currently pricing contracts to suggest the chances of another rate increase from the central bank this year are about fifty-fifty. As a result, 30-year fixed-rate mortgages are down for the fourth straight week and are the lowest they've been since mid-April. Meanwhile, ARM rates have gone down less. All of which could help persuade homeowners with ARMs on the verge of resetting to make the decision to lock into a fixed-rate mortgage now rather than take a chance of a higher rate on the adjustment date."
