Mortgage rates rose last week to the highest level in four weeks, but mortgage demand didn’t really move. Total mortgage application volume increased 0.8% last week from the previous week, according to the Mortgage Bankers Association’s seasonally adjusted index.

The average contract interest rate for 30-year fixed-rate mortgages with conforming loan balances, $806,500 or less, increased to 6.84% from 6.82%, with points remaining unchanged at 0.62, including the origination fee, for loans with a 20% down payment.

Applications to refinance a home loan, which are most sensitive to weekly rate moves, fell 3% for the week and were 22% higher than the same week one year ago, when interest rates were just 2 basis points lower. While the annual jump may seem large, that’s only because the volume is so very small.
