The Yen underwent a bearish session against most of the major currencies yesterday. The JPY dropped over 100 pips versus the Dollar, and over 200 pips against the Pound.

The Yen dropped yesterday on poor Retails Sales data. The report showed that the total value of sales at the retail level dropped by 3.0% in June, failing to reach expectations for a 2.5% drop. Furthermore, Japan's retails sales fell for a 10th month in June, making the longest losing streak since 2003. It seems that even though the Japanese economy is showing signs of recovering, mainly due to the positive export figures, the Japanese citizens are reluctant to resume last year's consumption levels, an indication that optimism may be lacking in Japan.

As for today, a batch of data is expected from the Japanese economy. Traders are advised to follow the Tokyo Core Consumer Price Index report. This report is a leading inflationary indicator for Japan, and thus tends to have a large impact on the JPY's value. If current expectations for a 1.7% drop will be similar to the real result, the Yen might continue to weaken against the major currencies in late-trading today.
