Factors affecting sentiment There were a lot of factors affecting sentiment this week. The recent correction in crude oil is the notable positive for the global markets. The U.S. Federal Reserve left its key fed funds rate unchanged at 2%. The Fed said "economic activity expanded in the second quarter, partly reflecting growth in consumer spending and exports," and that it expects "moderate economic growth" over time. But on Thursday, U.S. stocks slumped as investors considered reports showing higher borrowing costs, weaker spending, rising jobless claims and more bad news on the financial sector.
