After falling below 6%, matching their lowest level in several years, mortgage rates reversed course Monday, hitting their highest point in two weeks. The average rate on the popular 30-year fixed loan rose 13 basis points to 6.12%, according to Mortgage News Daily. It had fallen to a recent low of 5.99% on Feb. 23 and pretty much sat there all week. The drop was welcome news as the all-important spring housing market gets underway. Potential buyers have been sidelined by high home prices and concerns over the broader economy. Mortgage rates crossing into the 5% range broke an emotional barrier for some, suggesting buyers might jump at the opportunity. Mortgage rates loosely follow the yield on the U.S. 10-year Treasury, which rose back above 4% on Monday. The growing conflict with Iran caused a spike in oil prices, raising inflation worries and pushing yields higher.
