Germany on Saturday rejected media reports that Bundesbank reserves would be used to fund the Eurozone's rescue facility after German newspapers said Group of 20 leaders had discussed the idea of tapping central banks.

The Frankfurter Allgemeine Sonntagszeitung reported that Bundesbank reserves -- including foreign currency and gold -- would be used to increase Germany's contribution to the European Financial Stability Facility (EFSF) by more than 15 billion euros ($20 billion).

The European Central Bank would own the reserves, according to the paper, citing sources at the G-20 meeting held this week in Cannes, France.

The Welt am Sonntag newspaper, citing similar plans, said 15 billion euros would come from special drawing rights (SDRs) that the Bundesbank holds.

Germany's gold and foreign-exchange reserves, which the Bundesbank administers, were not at any point up for discussion at the G-20 summit in Cannes, government spokesman Steffen Seibert said.

G-20 leaders in Cannes discussed the idea that the European System of Central Banks could pawn their total foreign-exchange reserves of 50-60 billion euros to a trust of the European crisis fund in the form of SDRs from the International Monetary Fund, the newspapers said.

We know this plan, and we reject it, a Bundesbank representative said.

Seibert said several partners had raised the question in Cannes whether SDRs could be used to strengthen the EFSF, but Germany had rejected this plan, and discussions at a Eurogroup meeting on Monday would not include this topic.

The newspapers had said the issue was taken off the agenda at the G-20 following Bundesbank opposition, but that it would be debated on Monday at a Eurogroup meeting of Eurozone finance ministers.
