Pallade Veneta - Stocks rally before key Fed update, oil hits $90

Meanwhile, the main international oil contract hit $90 per barrel amid continued geopolitical tensions.

Wall Street's main indices snapped higher Wednesday, rebounding from Tuesday's losses, with the Dow up 1.1 percent in late morning trading.

Europe's major indices also ended the day with strong gains.

After weeks of uncertainty, the US central bank delivers Wednesday its views on the state of the world's top economy and how officials plan to tackle decades-high inflation without knocking its recovery off course.

While Fed boss Jerome Powell has pledged that interest rate rises would be carefully calibrated, the prospect of higher borrowing costs has rattled markets across the world.

Most key indices have been deep in the red from the start of the year -- with Wall Street particularly hard hit.

Powell's comments Wednesday will be pored over for signs of the Fed's plans, which most commentators believe include a first hike in March.

"The big question going into this meeting for traders and investors is whether the Fed will increase... four times this year and when the first interest rate hike will take place," said Naeem Aslam, chief market analyst at Avatrade.

Part of the market's exuberance may also be speculation that Powell may tone down his remarks about the need to aggressively raise interest rates.

"There is even some buzz that Fed Chair Powell won't sound as hawkish as feared when he holds his press conference," said analyst Patrick J. O'Hare at Briefing.com.

"That view may come back to bite the market," he added.

Despite recent stock market volatility, analysts believe investors remain relatively upbeat about the prospects for the global economy once the current wave of the Covid-19 pandemic wanes.

"Providing (a) boost to the stock markets is optimism that the economic recovery is going to speed up in the months ahead," said Fawad Razaqzada at ThinkMarkets.

Pent up demand for holiday travel will be unleashed as "travel restrictions continue to ease across Europe as Omicron cases decline and more people get double or triple vaccinated," he added.

Nevertheless, authorities are currently downgrading growth forecasts as the impact of the Omicron variant becomes clear.

Germany on Wednesday trimmed its 2022 growth forecast to 3.6 percent, down from 4.1 percent.

The International Monetary Fund on Tuesday lowered its forecast for global growth by half a point to 4.4 percent due to the Omicron variant and geopolitical tensions.

Included in those tensions is the standoff on the Ukraine-Russia border, with Moscow building up troop numbers and the West led by the United States warning the risk of an invasion "remains imminent" and urging its citizens to leave Ukraine.

The West has threatened to impose severe sanctions on Russia in case it goes forward with an invasion.

Those tensions helped push the price of Brent crude above $90 for the first time since October 2014.

"The fundamentals (of supply and demand) remain bullish for oil prices and the prospect of a Russian invasion of Ukraine will only increase the risk premium," OANDA analyst Craig Erlam told AFP.

"With the price now above $90 and gathering momentum once more, it may just be a matter of time until it's flirting with $100."
