LONDON (AFX) - The dollar's rapid appreciation against the yen continued in early trade following further intervention by the Bank of Japan, dealers said. The dollar has also gained ground as the safe haven flows into the Swiss franc continue to be unwound and the threat of unfocused military action against those thought to be behind the terrorist attacks in the US recedes. The latest confirmation by the Japanese authorities was confirmed earlier by Zenbei Mizoguchi, the Finance Ministry's senior deputy director general. Finance Minister Masajuro Shiokawa also said the government may ask the country's major economic partners to intervene in the forex market if necessary. Yesterday the ECB intervened for the second time on behalf of the Bank of Japan, as part of a long-standing arrangement. Jeremy Hawkins, chief economist Europe for Bank of America, said the European Central Bank may intervene once again on behalf of the BoJ, which he said would like to see dollar-yen somewhere back up the 120 level. The dollar has also been boosted by another slide by the Swiss franc. "The general pattern remains that the Swiss franc's safe haven status has been undermined by Monday's decision to cut rates," said Hawkins. "This has provided support for the euro and especially the pound." Sterling has rallied all week and today's GfK consumer confidence data provided some support, offset somewhat by the latest Mori findings. The markets will also be digesting the latest money supply figures from the eurozone countries, which showed adjusted June-August M3 up 6.4 pct year-on-year against 5.9 pct in the three months before. Even though there has been some weakening in Eurozone inflationary pressures, which was evident in Germany, economists don't expect the ECB to cut its key refi rate from 3.75 pct. Last week the ECB cut rates by 50 basis points.
