I think the markets expect just about any outcome, though I don't think an ECB or a Swedish rate hike would be seen as a surprise. However, a U.K. hike would be a surprise, given what sterling has done since the last rise.
The monetization of debt will reverse yen strength and release money to leave Japan, which has always been the big problem.
All of this adds ammunition to the argument that the ECB will tighten (monetary policy).
