German Finance Minister Wolfgang Schäuble | Sean Gallup/Getty Images Wolfgang Schäuble: World economy at risk of new financial crisis ‘Economists all over the world are concerned,’ says outgoing German finance minister.

Global debt and unstable loans could throw the world into another financial crisis, outgoing German Finance Minister Wolfgang Schäuble said in an interview with the Financial Times published Sunday.

“Economists all over the world are concerned about the increased risks arising from the accumulation of more and more liquidity and the growth of public and private debt," Schäuble said. "I myself am concerned about this, too.”

Schäuble, who is slated to become speaker of the Bundestag in Germany's new government, warned of new market bubbles forming, fueled by money pumped into the economy from central banks.

He also raise caution about potential weaknesses in the eurozone as banks struggle to deal with underperforming loans.

Schäuble will attend his last Eurogroup gathering of finance ministers on Monday.
