ML-Implode News - Currency Spikes at 4 P.M. in London Provide Rigging Clues

The same pattern -- a sudden surge minutes before 4 p.m. in London on the last trading day of the month, followed by a quick reversal -- occurred 31 percent of the time across 14 currency pairs over two years, according to data compiled by Bloomberg. For the most frequently traded pairs, such as euro-dollar, it happened about half the time, the data show.
...
The recurring spikes take place at the same time financial benchmarks known as the WM/Reuters (TRI) rates are set based on those trades. Now fund managers and scholars say the patterns look like an attempt by currency dealers to manipulate the rates, distorting the value of trillions of dollars of investments in funds that track global indexes.

But of course there's no way this could be happening in the precious metals... and no way that governments could be involved!
