* Swiss central bank may book Q4 loss of 11 bln Sfr
* Figure based on Swiss newspaper's own calculation
* SNB lost money on its reserves due to franc's rise
ZURICH, Jan 2 (Reuters) - The Swiss National Bank lost nearly 11 billion Swiss francs ($11.77 billion) on its currency reserves in the fourth quarter due to the franc's rapid rise against major currencies, a paper reported on Sunday based on its own calculations.
The Swiss central bank would likely post a full-year book loss of 32 billion francs, its largest ever, the newspaper Sonntag said.
The SNB has been criticised for running up massive losses on its holdings in its bid to combat a big appreciation of the Swiss unit against the euro.
The central bank, which dropped its pledge to intervene in June, recorded exchange-rate related losses of 21.2 billion francs in the first nine months of the year. [ID:nWEA9112]
The SNB's foreign currency reserves crept up to 212.4 billion Swiss francs at the end of November from 211.9 billion at the end of October, data published by the SNB showed. [ID:nWEA6003]
The SNB was unavailable to comment.
