Japan's finance minister dismissed as speculative on Monday a newspaper report that Japan was ending its massive intervention in the foreign exchange market, saying there was no change in the government's policy. "It is a speculative article. There is no change in our policy," Finance Minister Sadakazu Tanigaki told . The yen jumped earlier on Monday on a report in Britain's Times newspaper that quoted Bank of Japan officials as saying Japan was officially ending its intervention campaign. The Ministry of Finance, not the BOJ, is responsible for determining Japan's foreign exchange policy.////
