The rate of option ARM delinquencies is already spiking

According to a recent analysis by Lehman Brothers, option ARMs that originated in 2006 performed about as well as fixed-rate Alt-A debt for the first 12 months. But by the time they were 2 years old, about 2.1% of performing loans were going 60-days delinquent each month. Compare that to a 1.2% of current loans going delinquent with other Alt-A loans. The rate of increase in delinquencies is even beginning to approach that of subprime, which is about 2.5%.

“It’s a better quality borrower but the rate of increase in delinquency is looking closer to subprime than Alt-A,” said Akhil Mago, the head mortgage credit strategist for Lehman Brothers, said.

Looks like these borrowers might simply be giving up on the mortgages because they have less and less of an incentive to keep paying. Option ARMs give borrowers a choice of making a minimum payment that only covers a small portion of the interest, the rest of which is added to the loan balance. With years of unpaid interest accumulating and house prices falling, some homeowners have seen their equity disappear and now owe more than their initial loan balance.
