The yen hit a record low versus the euro and eight-year troughs against sterling and the Swiss franc on Monday, after reports of a coming missile test by North Korea and uncertainty on the timing of a Japanese rate hike. Against the dollar, the yen struck an eight-week low, with the U.S. currency supported across the board by expectations that the Federal Reserve will raise interest rates this month and then perhaps once more later in the summer. Japan warned Pyongyang of a "harsh" response from Tokyo and Washington if it went ahead with a test of a long-range missile amid reports that a launch was at hand. U.S. officials said North Korea appeared to have completed fuelling for a test of a long-range ballistic missile that could possibly reach as far as Alaska. "(North Korea) had a headline effect and the main thing today is geopolitical jitters which brought the dollar some support, in particular against the yen," said Adam Cole, currency strategist at Royal Bank of Canada Capital Markets. "The feeling is that the Bank of Japan will probably raise interest rates in July but it is in the price." By 1145 GMT, the dollar was up 0.25 percent on the day at 115.46 yen having hit an eight-week high of 115.77 earlier in the session. The euro rose as high as 145.86 yen , the strongest since the single currency was first launched in 1999. The yen was also under pressure as some in the market questioned whether the Bank of Japan would raise interest rates from virtually zero as soon as July or August. A sharp fall in Japanese equities could prompt it to delay tightening. Tadao Noda, new member of the BOJ's policy board, said the timing of a rate rise will depend on data and debate within the board.
