Kristalina Georgieva, IMF managing director, speaks on a panel at the World Economic Forum in Davos, Switzerland.

The Federal Reserve kept its key interest rate unchanged as officials grappled with uncertainty caused by inflation and President Trump's plans.

The biggest threat to the world economy in the next year is the prospect that inflation turns out to be persistent, former Swiss central bank chief Philipp Hildebrand said.

The Fed held interest rates steady as it continues to combat inflation. President Trump wants to see lower rates, but some of his policies could fuel more price hikes.

Economists and analysts aren’t convinced that an expansion of oil and gas production will lower consumer prices.

Consumers and traders are waiting to learn if the Fed’s pause is a one-meeting hold or the start of a longer stretch.

At the World Economic Forum, President Trump's return to the White House overshadowed traditional talk on climate change, trade and development.

Treasury yield surpassed 5%, it could "shock" the stock market and "force a revaluation," BlackRock's Larry Fink said.

I mean, get over it,” JPMorgan Chase CEO Jamie Dimon told CNBC on Wednesday from the World Economic Forum in Switzerland. “National security trumps a little bit more inflation.”

Global policymakers have made remarkable progress in tackling inflation without inducing a recession, but some work remains to be done, International Monetary Fund Managing Director Kristalina Georgieva said in Davos.

The Republican has promised strong growth, high tariffs, income tax cuts and booming oilfields. But despite the solid job market and low 4.1% unemployment rate, he has to contend with headwinds like inflation, a budget deficit, increased tensions over trade, the fallout from his plans to curtail immigration and a persistent wealth gap.
