The holiday-shortened week marked the third out of 4 during which rates worsened and last week's action happened to be especially harsh.
Monday's action was the worst for rates since July, for example.
Tuesday's was only slightly less worse.
Today, conforming, 30-year fixed mortgage rates have reached at a 15-week high -- well off the lows set in early-December.
Normally, when mortgage markets worsen this badly, this quickly, it's because of strong economic data, or growing inflationary expectations. Last week saw neither.
- Existing Home Sales showed strength, but was offset by New Home Sales
- 3rd Quarter GDP showed the economy growing at a slower-than-expected pace
- Inflationary data wasn't as high as was expected
And yet -- stock markets gained. All 10 sectors improved and they did so at the expense of mortgage bonds.
This week is again holiday-shortened so expect the same low-volume, high-volatility trading as last week. There's few data releases save for Tuesday's Case-Shiller Index. Therefore, watch for momentum trading in either direction.
Markets close early Thursday and re-open Monday, January 4, 2010. If you need to lock a rate, make sure of your loan officer's hours.
