The yen is the worst-performing G10 currency this year, with a 6.4% slide on the dollar. For the week the yen is down 0.6% on the euro, touching its weakest for three months overnight at 163.45 per euro . Yen moves against the dollar were more modest due to the risk its slide could prompt intervention in markets from Japan, with officials reminding traders they stand ready in recent days. The dollar gained 0.1% to trade at 150.41 yen this week. Investors can earn interest, or carry, by borrowing yen around 0% and buying income-bearing assets in other currencies.
