The yen experienced a bullish trading session yesterday, as it appreciated against most of its major currency pairs. The JPY extended gains versus the USD during yesterday's trading session and closed at 81.85. The Japanese yen also saw bullishness against the GBP as it jumped around 90 pips and closed at 0.8560.

Investors worry over a recent rise in the JPY as it makes Japanese products less competitive abroad and hurts the value of overseas sales when translated back into the Japanese currency. With steady gains primarily against the Dollar, much of the Yen's bullish movement could be contributed to the repatriation of overseas earnings by Japanese companies into the local economy. This has had a positive effect on major JPY currency pairings, as the rising turmoil in the market is leading to more investment in the Japanese currency.
