Is anyone here actually reading the article? Yes, they really made a gain of $15B:

> But instead of refining and transporting the gold, it opted to sell the bars and purchase new bullion in Europe. […] Due to rising gold prices, the move helped the bank to generate a capital gain of 13 billion euros ($15 billion),

Did they buy before selling? Otherwise that doesn’t make sense.
The gold price is fluctuating. It doesn't always go up.
