"Capital controls"? Bureaucratic heavy-handed disclosure rules, yes. But that isn't capital controls. From what I see, there are no restrictions there on taking money out of the USA. There is no unilateral withholding tax increase. They are being heavy-handed in trying to stop tax evasion by US citizens. They are not even taxing foreign or domestic capital on exit from the USA, let along outlawing it.
So why the capital controls headline? Unless I've missed something, it looks like more poorly-checked hyperbolic attention seeking from Zerohedge, which is becoming more and more like a conspiracy-theory obsessed rumour mill, and less a place of genuine financial reporting, as each day goes by.
