Mortgage rates rose quickly this morning after stronger than expected manufacturing data put pressure on the bond market. This places 30-year fixed rate mortgages at the highest level since August 22nd. Most lenders have reasonably priced 30-year loans starting at 4.625%.
House Speaker Boehner spoke this morning about the President's push for military action in Syria. This pushed stocks sharply lower, but mortgage rates were able to gain back some of their earlier losses of the day. Some banks and lenders offered slightly better rates by this afternoon, but the initial change in the market this morning caused enough damage to keep most investors unwilling to negotiate better prices.
Uncertainty over the Federal Reserve's bond-buying plans is also causing volatility in rates markets and generally leading rates higher.
Data to be released tomorrow, which may have an impact on rates, is the Federal Reserve's Beige Book. This is a survey of economic conditions. This is generally an indicator of how the Fed may act in its upcoming meeting.
