Yen

Shall we buy yen? Yes

The reason, in additional to the Japanese domestic economy, is that the govt/central bank is also debating the delink between US and the rest of the world/ asia I particular. Evidence is it is possible. If we have a delink, weaken or moderating US economy will discourage money flow into the US markets. Those extra money has to go somewhere. From currency prospective, Yen is the only outlier in the developed world. From geographical prospective, the delink is beneficial to Japan as its trade with Asia is highly connected. Both encourage the capital inflow to Japan. From the rest of the world prospective, reserve accumulation is slowing down. The major buyers in the past are either diversifiying or slowing down its rate of accumulation. I don't know how the global inflation and domestic US economy will play out in the US interest rate dynamic, but the long end of the US treasury will eventually feel the pressure from external.

The only problem is the Japanese policy makers are not 100% certain that delink will be the case. At this point, they are conservative because if delink has not yet be confirmed, earlier rate hike will be harmful to the economy. It will not materialize until the day it comes. Given the current oil price is highly uncertain, It looks like the bank wants to confirm the delink hypothesis before acting (which of course the mirror image of domestic economy pick-up).

Yes. It is expensive today. It will become cheap once the delink hypothesis is confirmed.
