Bloomberg reports: U.S. MBA's Mortgage Applications Index Fell 2.6% Last Week

U.S. mortgage applications fell last week to the lowest level since April as higher interest rates slowed both refinancing and home purchases, according to a private group's survey released today.

The Mortgage Bankers Association's gauge of applications declined 2.6 percent to 694.8 in the week ended Oct. 7 from 713.5 the previous week. The last time the index was as low was April 15, when it was 672.6.

The average 30-year fixed mortgage increased to 5.98 percent, the highest since the end of March and the fifth straight rise, according to the bankers group. Higher borrowing costs have caused purchase applications to decline in each of the last four weeks, suggesting home sales are starting to cool.

According to the Mortgage Bankers Association (MBA) the refinance share of activity declined as did the share of ARMs:

The refinance share of mortgage activity decreased to 43.5 percent of total applications from 44.5 percent the previous week. The adjustable-rate mortgage (ARM) share of activity decreased to 29.5 percent of total applications from 29.8 percent the previous week.
...
The average contract interest rate for one-year ARMs increased to 5.26 percent from 5.13 percent one week earlier.

The spread between the 30 year interest rate and the 1 year ARM is now 0.72 basis points; the lowest spread since March 9, 2001.

The Riddles

With rising interest rates, why is the refinance activity so high?

With the narrow spread between fixed rate loans and ARMs (and rising rates) why is anyone using an ARM?

From Bloomberg: Bob Walters, chief economist at Quicken Loans Inc. said they are seeing more people refinance out of their adjustable rate mortgages to fixed-rate mortgages in anticipation of higher borrowing costs. That is a similar explanation as in the LA Times article, "Thinking long-term" that described similar motives of homeowners refinancing their variable rate loans to lock in the security of a fixed rate loan.

This can at least partially explain why refinance activity remains so strong, but I expect that activity to diminish rapidly. With both adjustable and fixed rates rising (and widely advertised to keep rising), those homeowners motivated by locking in a fixed rated will probably refinance soon.

But that doesn't explain the high level of ARM activity. Why is anyone using an ARM today?

Here are two possible explanations: 1) new homebuyers are continuing to stretch to buy a home and 2) existing ARM users are refinancing with ARMs to get a new low teaser rate.

If new homebuyers are using ARMs that is most likely a sign of speculation. With the current spread and direction of rates, I would expect new buyers to use fixed rate loans if they could afford the payments.

The second explanation was described in this LA Times article: Risky 'Exotic' Loans Fostering a Refi Cycle. Apparently many borrowers are desperately replacing existing ARMs and IOs with new ARMs and IOs to forestall higher payments. They are hoping the price appreciation in their homes will bail them out. This is a short term strategy and the day of reckoning is probably soon.

If the riddles are solved, the solutions are not healthy for the housing market. I expect the refinance activity to diminish rapidly and speculation (ARM users) to almost disappear as short term rates rise and the housing market slows.
