The Bank of Japan surprised the markets by adding more stimulus, including an increase of asset purchases to ¥80-trillion from the ¥60-70-trillion range. This move came after 18-months of inactivity, as the bank waited for the already existing historical stimulus measures to work toward the 2.0% target inflation rate. The surprise stimulus caused a sharp JPY-sell off, as one would expect. Let's take a look at couple of reactions, which basically represent all the JPY-pair reactions.USD/JPY 4H Chart 10/31 After a bearish correction in the first half of the month from about 110 to 105.19, USD/JPY has been recovering. Mid-week, the FOMC announced the end of QE and the pair rallied further. Then the BoJ announcement boosted it above the previous 2014-high around 110. At this point, the next common support/resistance area will be around 114.87-115. Furthermore, the 109.50-110 area might now become support upon a pullback.EUR/JPY Daily Chart 10/31While the USD/JPY has already been in stride, most JPY-pairs have been consolidating in 2014. Take EUR/JPY for example. It has been in an uptrend since 2012, but has been in a slightly downward channel since Dec 2013's high at 145.69. This looks like a pennant, a consolidation pattern, which is now being tested after the latest reaction to the BoJ announcement. A break above 141 should clear the consolidation pattern and bring the 143.78 and 145.69 highs into play, with risk of further upside to extend the uptrend since 2012.
