English/Nat The American dollar has recovered slightly from record lows against the yen following intervention by the Japanese central bank. The central bank intervention also helped to boost the depressed Tokyo stock exchange with the index rising by more than 1.5 per cent. Exchange rates on Tokyo's foreign exchange market gyrated as the Japanese central bank tried to support the ever weakening dollar. Japanese Finance Minister, Masayoshi Takemura, released a written statement early on Tuesday morning pledging continued contact with other monetary authorities in a bid to stabilize developments in the world economy. Stocks traded down for the first hour of trading but picked up by the close of the morning session. Since the beginning of the year, the dollar has lost 13 percent of its value against the yen, pushing up the price of Japanese exports beyond competitive prices. The erratic trends on both the stock and foreign exchanges casts doubts on Japan's economic recovery which was making slow progress. SOUNDBITE: It seems to us that appreciation of the yen is a factor common to other currencies against the dollar. We still see the currency market being one of dollar weakness rather than just yen strength. But with regard to the domestic situation, the strong yen is just one of a number of factors which is helping to depress the stock market. But of those factors undoubtedly the currency is the greatest. SUPER CAPTION: Chris Calderwood, Barclays Bank Chris Calderwood believes it will take policy changes to curtail the current trend SOUNDBITE: It seems to us like the US policy makers are beginning to become more concerned by the weakness of the dollar. But it is important to remember that because most American imports are priced in dollars anyway the inflationary impact of a weak dollar is relatively limited. So in terms of how much U.S. policy makers should be concerned by the dollar weakness is not that great. And the halting of the dollar slide really depends on a shift in policy in currency as well as a shift in policy in Japan and Germany. SUPER CAPTION: Chris Calderwood, Barclays Bank The Bank of Japan intervened again on Tuesday morning, and the dollar had rallied to trade just above the 86 yen line by the end of trading.
