The Swiss National Bank has reported a 20 per cent increase in profit to SFr1.86 billion ($2.13 billion) for the first quarter of 2011.
The result rests largely on profits from foreign currency positions, which increased to SFr1.6 billion compared with a loss of SFr872 million for the same period a year earlier.
The bank said strong fluctuations in the results were normal as its business depends mostly on gold, foreign exchange positions and capital markets.
The SNB, which holds 1,040 tonnes of gold in the form of currency reserves, said the net result from gold was low at SFr11.5 million as the price of gold had not moved significantly compared with the previous year.
