Even as overall weekly mortgage applications decelerated, refinance share reached a 10-week high. The spread between conforming and jumbo interest rates was at its widest in 15 weeks.

A seasonally adjusted 5 percent increase from the preceding week was recorded for the Market Composite Index for the seven-day period ended June 22.

When seasonal factors are disregarded, however, the index — a measure of retail residential loan applications — retreated 6 percent from the week ended June 15.
