Federal Reserve policy makers began their two-day meeting on Tuesday and are expected to announce tomorrow a third US$10 billion reduction in their monthly bond-purchase programme, which would reduce it to US$55 billion. Janet Yellen will lead her first post-FOMC-meeting press conference as Fed chairman on Wednesday.
"Yellen's Fed will be revealed in detail tomorrow," Pimco's Bill Gross wrote on Twitter. "Expect focus on inflation, less focus on employment."
Investors were relieved, for now, that Russian President Vladimir Putin said he would respect the independence of what's left of Ukraine as he signed a treaty annexing Crimea following Sunday's referendum in which voters opted to rejoin Russia.
"The words that market participants wanted to hear were that he'll respect Ukraine's sovereignty and will be satisfied with Crimea, and won't go for more," Benno Galliker, a trader at Luzerner Kantonalbank in Lucerne, Switzerland, told Bloomberg News. "These words were heard, and we're seeing a relief nudge up."
In Europe, the Stoxx 600 Index finished the day 0.6 per cent higher than the previous close, as did the UK's FTSE 100. Germany's DAX gained 0.7 per cent, while France's CAC 40 rose 1 per cent.
Gold dropped as a result as the need for a perceived safe-haven investment diminished. Gold futures for April delivery fell 1.3 per cent to US$1,355.40 an ounce.
To be sure, the relief might prove temporary.
Investors "don't know how bad the sanctions are going to be, or if it escalates into a military buildup from the West," Michael Franzese, senior vice president of fixed-income trading at ED&F Man Capital Markets in New York, told Bloomberg News. "That's where the fear is."
A report showed German investor confidence slid for a third month in March, declining more than expected to 46.6, down from 55.7 in February. Germany relies heavily on Russia as an energy supplier.
