The overview of the January Euroyen markets is follows:
Euroyen prices went up gradually on the first half of January with growing speculation that Bank of Japan(BoJ), Japanese central bank, might return to so called "zero interest rate policy" to sustain Japanese economy.
On 19th, the prices of Euroyen futures soared after an announcement of Chairman's instruction to the BOJ's staff that "...the staff will examine the possible room for further improvements in the way of liquidity provision to the market...". Prices remained high level to the end of January.
