Lender Processing Services (LPD) will be reporting a huge spike in the U.S. Loan delinquency rate when it releases its Mortgage Monitor for June. Its usual advanced release of some Monitor data shows the total delinquency rate for June was 6.68 percent, a 9.91 percent increase, month over month,  in the rate which includes loans 30 or more days past due but not in foreclosure. This jump follows five straight months of decline. The company offered no explanation for the surge beyond referring to it as "seasonal".

There were 3,328,000 mortgage loans in the 30+ delinquent category at the end of June. Of these loans, 1,345,000 ​ are seriously delinquent, that is 90 or more days past due.

There is better news for the foreclosure pre-sale inventory rate, the number of mortgages in some stage of foreclosure, which continued to decline and is now at 2.93 percent. This is a month-over-month change of -3.92 percent. There are 1,458,000 loans in this category.

Delinquencies are down 6.50 percent from the rate in June 2012 and the foreclosure inventory has decreased by 28.4 percent.

LPS will release its complete report by August 5 and perhaps will then clarify the reason for the sudden increase in delinquencies.
