There is plenty of anticipation for a QE
upgrade from the BoJ, but it sounds more like hope from speculators rather than concise analysis as to why more stimulus would generate long-elusive economic objectives. Without more stimulus, we may find the Yen crosses start to retreat in earnest. Without the BoJ's QQE program ( Apr
4, 2013) and its subsequent upgrade (Oct 31, 2014), USDJPY
and other Yen crosses may have been much lower than current price.
