Gold Swaps

Já aqui tinham os leitores deixado esta informação mas aqui fica um link para a notícia no Telegraph.

Gold swaps spook the market.

At first it looked like the BIS was swapping gold with a troubled central bank. After all, the institution is the central bankers' bank and its purpose to conduct transactions with national monetary authorities.

Central banks in the troubled southern zone of Europe were considered the most likely perpetrators [...] leading analysts to point fingers at Portugal, or a combination of the three.

Mas mais provavelmente:
[T]he counterparty was the IMF, making sense because the lender of last resort is historically prone to cash shortages and has been quietly selling off gold in the first half of the year.
