German Finance Minister Wolfgang Schäuble has warned that spiralling levels of global debt and liquidity present a major risk to the world economy.

In an interview with the Financial Times, the minister said that there was a danger of “new bubbles” forming due to the trillions of dollars that central banks have pumped into markets.

Schäuble also warned of risks to stability in the eurozone, particularly those posed by bank balance sheets burdened by the post-crisis legacy of non-performing loans.
