The average interest rate on the most popular US home loan rose to its highest level since 2001 as tightening financial conditions weigh on the housing sector, data from the Mortgage Bankers Association (MBA) showed on Wednesday. The average contract rate on a 30-year fixed-rate mortgage rose by 22 basis points to 7.16% for the week ended 21 October while the MBA’s Market Composite Index, a measure of mortgage loan application volume, fell 1.7% from a week earlier. Mortgage application activity is at its slowest pace since 1997. Mortgage rates have more than doubled since the beginning of the year, as the Federal Reserve pursues an aggressive path of interest rate hikes to rein in stubbornly high inflation. The central bank is expected to raise rates by 75 basis points for a fourth straight time at the conclusion of its next policy meeting on 1-2 November. Those actions, designed to cool the economy sufficiently to curb price pressures, have weighed heavily on the interest-rate-sensitive housing sector as expectations for Fed tightening have led to a surge in Treasury yields.
