Mortgage markets improved last week in response to mostly negative data about the U.S. economy, and the Federal Reserve’s acknowledgement that Eurozone financial ills could cross the Atlantic.

Conforming and FHA mortgage rates fell last week, extending a rate rally that dates to early-April.  Mortgage rates have fallen to several, new, all-time lows during this period and last week was no different.

The best rates of last week hit Thursday morning.

This week, mortgage rates should be volatile, and may rise, too.  There’s a bevy of data due for release, and market volume will be light with the long weekend looming.

Monday, the Personal Consumptions Expenditures Price Index is published. More commonly known as “PCE”, the index is the Federal Reserve’s preferred inflation gauge. When inflation is running higher than expected, mortgage rates tend to rise.

Conversely, when inflation is running lower than expected, mortgage rates tend to fall.

Tuesday, the Case-Shiller Index will be released for April’s home prices, along with two consumer confidence reports.  As with PCE, strength tends to lead mortgage rates higher and weakness draws them lower.

Thursday, the National Association of REALTORS® releases its Pending Home Sales Index for May and the Department of Labor releases initial and continuing jobless claims number.

Then, Friday, the Bureau of Labor Statistics publishes June’s jobs report, including the Unemployment Rate.  This number is always a market-mover, but with the long vacation weekend looming, it’s expected that Friday’s volume will be light on Wall Street, creating extra volatility. 

Mortgage rates may be erratic, in other words.

If you’ve been shopping for mortgages, you’ve been rewarded with falling rates. However, will rates cutting new lows almost weekly and expected to reverse soon, it may be a good time to lock up your savings.

Talk to your loan officer ASAP about locking in your rate.

Mortgage markets improved last week as economic reports painted a less-than-stellar portrait of the U.S. economy and concerns of a looming monetary policy change eased. Mortgage pricing improved dramatically, despite a late-Friday retreat.

Mortgage rates are now at their lowest levels since early-February.

Last week was heavy on negative data:

• Consumer Confidence posted 16% short of expectations
• New Home Sales posted 13% short of expectations
• Initial Jobless Claims were higher than expected

In addition, both the Case-Shiller and Home Price Indices showed a slight pullback in the housing sector.

The impact of these statistics was muted, however. This is because Fed Chairman Ben Bernanke gave his semi-annual outlook to Congress and markets focused more on the chairman verbiage than hard data, looking for clues about the future of Fed policy.

Bernanke stayed on message — the Fed Funds Rate will stay low for an extended period of time.

Mortgage rates were also helped by a strengthening U.S. dollar and demand for U.S.-denominated bonds. When demand for mortgage-backed bonds is strong, mortgage rates fall.

This week, mortgage rates will jockey around Friday’s Non-Farm Payrolls report.

Jobs are playing a large role in mortgage bond trading and markets expect that 30,000 jobs were lost in February.  If the actual figure is better than 30,000 jobs lost, mortgage rates will rise. If it’s worse, rates will rise.

Other important data this week include Personal Consumption Expenditures — the Fed’s preferred inflation gauge — plus the Fed’s Beige Book release.  Mortgage rates remain in flux so float with caution.

Mortgage rates look good today, but by Friday, they could be much, much worse.
