Fixed-rate mortgages soared this week and are now at their highest level in nearly 10 months.

The average 30-year fixed-rate mortgage jumped 26 basis points, to 6.52 percent. A basis point is one-hundredth of a percentage point.

The average 15-year fixed — a popular option for refinancing — shot up even higher, rising 28 basis points, to 6.12 percent. The average jumbo 30-year fixed was up 13 basis points, to 7.6 percent.

The one-year adjustable-rate mortgage was up just 2 basis points, to 6.16 percent. However, the popular 5/1 ARM jumped 27 basis points, to 6.07 percent.

Mortgage applications rose sharply after three straight weeks of decline, according to the Mortgage Bankers Association. For the week ending June 6, applications rose a seasonally adjusted 10.9 percent when compared to one week earlier.

Refinancing grew by 8.4 percent while applications for new purchases increased 12.8 percent.
