EUR/JPY - This is the forex quote for the Euro vs. Japanese Yen exchange rate. EUR (the 'base currency') is quoted in terms of JPY (the 'counter currency'). The Yen is a historically low-yielding currency, making an attractive vehicle to fund carry trades (where traders borrow cheaply in JPY to buy higher-yielding currencies, including EUR. Investors tend to favor carry trades at times of optimism about global economic performance and stability; they shun them at times of market stress. This makes EUR/JPY sensitive to swings in broad-based market sentiment trends. The pair may likewise find volatility in news-flow related to the Eurozone debt crisis as well the extraordinary anti-deflation policy efforts from the Bank of Japan introduced in 2013.
The US data today will do little to change Fed rate expectations, but Q4 should change the complacent state of the market.
