So we now have the break above 152.
Question is will this hold (will BOJ/MOF) intervene to try to keep a lid on it. I suspect at this moment the verbal intervention will continue but massive physical intervention is unlikely. Historically the Japanese have tried to dampen sharp moves and volatility and have not been married to particular "levels". there is nothing "special" about 152. If anything /Yen likes big round numbers so perhaps we shall see 160 in coming weeks/months.
