Having watched the currency markets for long enough to know, I am certain that they are among the most regularly interfered-with of them all.
In this article it is openly speculated that perhaps a joint support of the dollar is in the works:
[quote]Sept. 29 (Bloomberg) — A growing number of currency traders and strategists are starting to speculate that finance ministers from the world’s biggest economies will join to support the dollar.
"We’re getting closer to the right conditions for authorities to step in and prop up the dollar,” said Maxime Tessier, who manages $151 billion as head of foreign exchange in Montreal at Caisse de Depot et Placement. "The nightmare scenario will be a wholesale loss of confidence in the dollar.”
"The central banks of the world have embarked on all sorts of extraordinary interventions,” said Stephen Jen, the global head of currency research at Morgan Stanley in London. "Currency joint intervention would be the least surprising. And it would probably be the cheapest.” [/quote]
I find it remarkable that they did not find a single quote from somebody who thought that the 9% gain in the dollar against the Euro was already a clear sign of manipulation.
To me it is utterly improbable that the dollar rose, even as the US lost all but two of its investment banks, bailed out its largest insurance company, and suffered the largest bank failure in history. To explain this, I have to assume that whomever was buying the dollar and selling the Yen and the Euro was doing so for reasons that were not economic in nature.
