Japan is one of the largest holders of US treasuries outside of America. Japan has had quantitative easing for over a long period of time, much more than what we've had in Europe and in the US. It's not clear how risk sentiment would do well if they were to suddenly abandon yield curve control. The local market handle it? How much do JGB sell off? That's a significant daily selloff. But you know what markets are like in these sort of shock scenarios,. You can get a sort of non-linear market reaction, then it feeds through to US Treasuries.
