Ueda's Speech to Test Yen's Lows Against Dollar

The yen's relentless slide has investors looking to Bank of Japan Governor Kazuo Ueda for guidance. After the central bank's policy meeting on Friday, Ueda's comments will be closely watched by traders who are waiting for any indication that he might try to calm the market.

While the BOJ is expected to keep interest rates unchanged, a misstep in Ueda's words could trigger further weakness in the yen. It has already fallen to its lowest level against the dollar since 1986 in June and continues to decline this month.
