Where is the money going? Is this 'sell America'?
The shift from the dollar has helped to fuel a surge in the price of gold, sending its price doubling over the last year, as investors seek a low-risk place to put their money.
And though other national currencies appeared to get little boost from redirected funds last year, there are signs that could be starting to change.
The Euro and pound were among the currencies to see their values leap against the dollar this month, while eleven of the 19 emerging market currencies tracked by Oxford Economics also gained more than 1%.
Global investors might also be turning against the US, with pension funds in Amsterdam and Denmark cutting back holdings of US Treasuries.

However, Turner of ING said he thought markets were still well way from a "full 'sell America' narrative", noting that the sell-off action has been largely limited to the dollar.
He and others noted that the US stock market is still hovering around record highs, while moves in the market for US government debt have been relatively contained.
Still, ING is expecting the dollar to fall another 4% to 5% this year, as growth prospects outside of the US improve.
Does Trump actually want a weaker US dollar?
For now, the dollar's falls remain small enough that the impact for American consumers is likely to amount to "noise", Brooks said.
But what happens next will depend in part on US economic performance and how quickly the US central bank will lower interest rates.
Trump has mounted an intense campaign for lower interest rates more quickly and is expected to install someone more sympathetic to those demands to lead the bank in the next few months.
If rates do fall, that might lower the dollar further as investors chase higher returns elsewhere.
But the White House could see that as a good thing, as Trump and other White House officials have previously welcomed the idea of a weaker dollar, which can help make US exports more competitive.
"It doesn't sound good, but you make a hell of a lot more money with a weaker dollar... than you do with a strong dollar," Trump said in July. This week, asked about the falls, he said he thought the currency was "doing great".
Brooks said a sustained drop in the dollar's value could help boost US firms - but warned that the pay-off might be limited if it happens for the "wrong reasons".
If it's the market rendering a verdict on poor policies, he warned "that is probably a very important signal".
