Yen is falling v the dollar I think ...
Someone should do an essay comparing the trajectories of US and Japanese (net) public debt, and the forward looking forecasts of Japan's primary balance v that of the US ...
I would believe a fiscal story for JPY/ KRW a bit more!
How can you explain the continuously falling Yen even though Japan's interest rates are rising? The explanation is that Japan's shadow yield - the yield markets require to compensate them for the risk of a debt crisis - is rising faster than actual yields.
