Bank of Japan Deputy Governor Shirakawa â€“ the acting BoJ Governor â€“ today said (Japanâ€™s economy) is now facing many risks from both within and outside the country, such as the global financial market instability caused by the U.S. subprime loan issues and dwindling profits of Japan's mid- and small-sized companies. In making policy, the BOJ must analyze these risks broadly, and also take into considerations the mid- and long-term economic conditions, as well as the current ones. Shirakawa touched on exchange rates saying The recent volatility is reflecting the process of adjustments and risk-reassessment in the international financial market. It may take some time. Some traders believe the central bank will be forced to reduce interest rates this year.
