Today’s CPI report signals deflation, or a prolonged price slide, may become another hazard facing Federal Reserve Chairman Ben S. Bernanke and President-elect Barack Obama. Deflation could worsen the economic downturn by making debts harder to pay off and countering the impact of Fed interest-rate cuts.

“The economy’s really just in horrific shape,” said Joseph LaVorgna, chief U.S. economist at Deutsche Bank Securities in New York. Fed officials will “take rates as low as they have to” to avoid “a deflation-type scenario, which now all of a sudden is very possible.”

LaVorgna predicts the Fed will cut its main rate to 0.5 percent from its current 1 percent when it meets on Dec. 16.

Fed Vice Chairman Donald Kohn said today that while the risk of deflation is “still small,” policy makers must be “aggressive” in fighting the danger. The economy “is declining right now” and will record a couple of quarters of contraction, he said in answering questions after a speech in Washington.

Fed policy makers last month forecast the U.S. economy will contract through the middle of 2009, with some officials prepared to cut interest rates further in response, according to a record of the group’s meeting.

If the Fed’s thinking of cutting rates further, why aren’t San Marino mortgage rates going down?  I think it’s because the Fed has done all it can do.  Future rate cuts are like that eighth scotch.  Drinking that eighth scotch isn’t going to make you feel any better than the seven prior.  It just might make you feel worse.

I advised folks, right after the election, to lock loans with rates under 6% if they were closing within 30 days.  Today, I”m suggesting that you lock any loan on a home that you are purchasing in San Marino that is closing this year.  Today, a 45-day lock for a 6.0% rate would costs 1.25%.  While you may see rates drop below 6% , in the next 45 days, the risk of them moving higher is greater.

Take 6% and run.
