The Fed lowered the Fed Funds Rate by 0.250%. The rate decrease was not well-received, though, as many investors were calling for a deeper cut of a half-percent.
In response, dollars moved from stock markets to bond markets and, therefore, mortgage rates fell.
Because it is tied to the Fed Funds Rate, Prime Rate fell by 0.250% yesterday, too. Holders of home equity lines of credit and credit card debt benefited from the change and will see lower interest costs in next month's statements.
In the statement above -- as explained by The Wall Street Journal -- the Fed expresses concern about the consumer and business slowdowns. This leaves the possibility of future Fed Funds Rate cuts open.
