Investors around the world once again turned to the Fed for clues about monetary policy.
Yellen testified before the Senate Banking Committee this morning. She blamed recent lackluster economic data on unusually bad weather, but said it is difficult to pinpoint exactly what effect the weather had on the economy overall.
The Fed has asserted that the economy is steadily improving. As such, it began dialing back, or tapering, the size of its monthly bond purchases in December. It currently is buying $65 billion in bonds per month, down from $85 billion a month last year.
Market strategists expect the Fed to keep scaling back its bond-buying program, but listened in to Yellen for hints about when the central bank may raise interest rates. To that end, Yellen maintained the Fed's stance that interest rates will stay low for some time. Still, minutes from the Fed's January meeting showed some internal debate about whether rates should be raised sooner rather than later.
Yellen was originally scheduled to speak two weeks ago when she also testified before the House, but her appearance was delayed due to bad weather. Stocks rallied following her comments two weeks ago.
Investors were also keeping a close eye on the tension in Ukraine. European markets finished the day mixed as traders fretted about the formation of a new Ukrainian government and its increasingly dire economic situation. Asian markets also ended with mixed results.
