“It’s been no secret that China views FATCA very unfavorably and negotiations towards compliance are going nowhere. It seems unlikely that the US would hit China with the 30% withholding tax for non-compliance. With China holding roughly $1.2 trillion in US Treasuries, it’s not as if it lacks its own leverage over the US government. This leaves the FATCA juggernaut stuck in a Sino-US standoff. It appears the US will have to either make serious concessions to win China over or back down on the 30% non-compliance tax. Should China stand its ground and not compromise on FATCA, it would punch a massive hole in global compliance.”
