Speaking at a banking conference in Frankfurt on Friday, Mr Schäuble said it would be “naive” to assume the next asset price bubble would take the same guise as the last.
He said: “More likely today is a scenario in which excess liquidity globally creates a new [sort of] asset market bubble.”
He added: “That low interest rate currencies such as the US dollar are increasingly being used as a basis for currency carry trades should give pause for thought. If there was a sudden reversal in this business, markets would be threatened with enormous turbulence, including in foreign exchange markets.”
